What Is SafeRec Certification and Why Does It Matter to Recruitment Agencies?

Compliance has always mattered in recruitment, but the level of visibility expected across the labour supply chain is changing.

Recruitment agencies are increasingly expected to understand not only who they are working with, but how workers are being paid, how deductions are being handled and whether the suppliers within their chain can provide clear evidence of compliant practices.

That is where SafeRec Certification comes in.

What is SafeRec Certification?

SafeRec is a compliance framework designed to give recruitment agencies, and end clients greater visibility over the umbrella companies operating within their supply chain.

Rather than relying solely on periodic checks or self-declared compliance, SafeRec uses ongoing auditing and verification to assess how certified umbrella companies operate.

This includes real-time payslip auditing, verification against RTI information submitted to HMRC, checks of HMRC tax accounts and legal and operational reviews of contracts, policies and processes.

Certified umbrella companies are also required to provide transparency around their operations, giving recruitment agencies access to due diligence information and ongoing audit data.

Why does real-time compliance matter?

A traditional compliance review can provide a useful snapshot of a business at a particular point in time.

The challenge is that payroll does not happen once a year.

Workers are paid every week or month, tax information is continually submitted and circumstances across a supply chain can change.

SafeRec’s model is designed to provide ongoing visibility by auditing payroll data as it is generated and comparing payslips with RTI information submitted to HMRC. SafeRec also carries out additional verification throughout the certification period.

For recruitment agencies, that provides another level of evidence when assessing the umbrella providers they choose to work with.

What does SafeRec Certification mean for recruitment agencies?

Recruitment businesses already have plenty of competing responsibilities, from candidate experience and client relationships to payroll, legislation and internal compliance processes.

Having independently verified information available can make supplier due diligence clearer and easier to evidence.

SafeRec gives agencies access to information covering areas such as:

• Ownership and company structure
• Payment models and tax treatment
• Insurance and compliance documentation
• Contracts, policies and processes
• Legal review information
• Ongoing payroll and payslip auditing

Agencies can also receive compliance alerts and maintain records of their due diligence activity through the SafeRec platform.

This is particularly valuable when clients, procurement teams or internal stakeholders want greater reassurance about how workers within the supply chain are being engaged and paid.

Protecting contractors as well as agencies

Strong compliance processes are not simply about reducing commercial risk.

Ultimately, there is a worker at the end of every payroll process.

SafeRec’s forensic auditing is designed to identify discrepancies within payslips and check areas including gross pay, statutory deductions, tax and National Insurance.

Workers using a SafeRec Certified umbrella can also access information relating to the auditing of their pay, helping create greater transparency around how their earnings have been calculated.

For recruitment agencies, choosing suppliers that provide this level of visibility can support both contractor protection and the reputation of the agency itself.

Why is supply chain visibility becoming more important?

The direction of travel across the recruitment and labour market is clear: organisations are being expected to understand their supply chains in greater detail.

The Fair Work Agency launched on 7 April 2026, bringing together several existing labour market enforcement functions. Its first delivery plan sets out an increasingly joined-up and intelligence-led approach to enforcement and information sharing.

For recruitment businesses, this makes robust supplier selection and documented due diligence increasingly important.

The question is no longer simply, “Is this provider accredited?”

It is also, “What evidence do we have that they continue to operate compliantly?”

What does Sterling’s SafeRec Certification mean for our partners?

For The Sterling Group, SafeRec Certification adds another independent layer of scrutiny to the compliance processes already embedded within our business.

It means agencies working with Sterling have access to greater transparency around how payroll is processed and can draw on independent due diligence and ongoing auditing as part of their own compliance procedures.

For us, that matters because compliance should never rely on reassurance alone.

It should be demonstrable.

Our recruitment partners need to know that the providers within their supply chain are prepared to open their systems and processes to scrutiny, maintain high standards and provide the evidence to support them.

SafeRec Certification is another way we can provide that confidence.

Building a stronger, more transparent supply chain

No individual accreditation should replace an agency’s own due diligence.

But strong independent verification can provide valuable evidence and help recruitment businesses make more informed decisions about the suppliers they choose.

As scrutiny across the sector continues to increase, transparency will only become more important.

For agencies reviewing their umbrella PSL, strengthening their compliance processes or simply looking for greater visibility across their supply chain, working with providers that can demonstrate how they operate is a sensible place to start.

Payroll rarely gets a standing ovation.

Nobody gathers around the office kitchen to celebrate a perfectly processed timesheet. Recruiters do not usually send congratulatory messages because every contractor was paid correctly and on time. And there are very few awards for “most satisfyingly straightforward payslip”.

But maybe there should be.

Because when payroll works properly, everything else works better.

Contractors feel confident. Recruiters spend less time chasing answers. Clients have fewer reasons to worry. Finance teams can get on with their day. And everyone involved in the supply chain gets the reassuring feeling that somebody, somewhere, knows exactly what they are doing.

That is why National Payroll Week is worth celebrating.

At The Sterling Group, payroll is not background admin. It is one of the things that keeps recruitment businesses moving.

And after 27 years in the industry, we have learned a thing or two about what makes a genuinely good payroll partner.

Payroll Might Be Behind the Scenes, but Its Impact Is Everywhere

Payroll is one of those functions that tends to stay invisible when everything is running well.

The moment something goes wrong, it becomes extremely visible.

A missing payment does not stay inside the payroll department.

It becomes a contractor query.

Then a recruiter query.

Then potentially an account manager query.

And before long, something that should have been routine is eating into several people’s day.

That is why choosing the right payroll partner matters.

For recruitment agencies, payroll affects:

• Contractor experience
• Internal administration
• Compliance confidence
• Agency reputation
• Client relationships
• The overall quality of every placement

Good payroll keeps things moving.

Great payroll helps make the whole recruitment process feel easier.

That is the standard Sterling aims to deliver.

Reason One: We Believe Reliability Is a Habit

Reliable payroll is not about getting it right once.

It is about getting it right again.

And again.

And again.

Every week.

Contractors expect to be paid accurately and on time. Agencies expect payroll to happen without unnecessary drama. Nobody wants Friday afternoon to become an investigation.

Sterling provides fast and accurate weekly payroll processing across our umbrella and CIS services, supported by experienced teams who understand how important consistency is.

Because reliability is not the exciting part of payroll.

Until it disappears.

Then suddenly it is the only thing anyone wants to talk about.

Our job is to keep payroll boring in the best possible way.

Accurate. Consistent. Dependable.

Just how it should be.

Reason Two: Compliance Is Built Into the Conversation

Payroll compliance should never be treated as a nice extra.

For agencies, contractors, and end clients, strong compliance processes help protect the entire labour supply chain.

That means agencies need payroll partners who can demonstrate how they work, explain their processes clearly, and provide confidence that compliance is taken seriously behind the scenes.

The Sterling Group is FCSA approved, and Sterling Solutions Umbrella Limited, Sterling Solutions Rail Limited and Sterling CIS Limited have achieved Workforce Assured accreditation.

Those standards matter because agencies should not have to rely on vague claims.

If a payroll provider says they take compliance seriously, there should be something behind the statement.

Processes.

Checks.

Documentation.

Expertise.

Evidence.

That is especially important as agencies continue to strengthen due diligence and review the partners operating within their supply chains.

National Payroll Week might be a celebration, but compliance is one area where we are very happy to keep things serious.

Reason Three: We Make Life Easier for Recruitment Agencies

Recruiters have enough to do.

Payroll should not quietly become another full-time job.

A good payroll partner should reduce administration, not create it.

At Sterling, we support agencies with dedicated account management, straightforward processes, and clear communication.

That means your team has somewhere to go when they need an answer.

No mystery inbox.

No unnecessary bouncing between departments.

No “we’ll try to find out who deals with that”.

Just clear routes to support.

The aim is simple.

Let recruiters focus on recruitment.

Let payroll people focus on payroll.

Everybody wins.

Reason Four: Contractors Matter Too

The agency relationship does not stop when a contractor is referred to a payroll provider.

The contractor experience continues.

And every interaction they have with that provider can reflect back on the recruitment agency that introduced them.

That is why contractor support is such an important part of choosing the right payroll partner.

At Sterling, we focus on making the process clear from the beginning.

That includes:

• Simple onboarding
• Transparent communication
• Access to account information
• Responsive customer support
• Clear payroll processes

Our Contractor Portal also gives contractors the ability to view their account information whenever they need it.

Because the fewer mysteries surrounding payroll, the better.

Contractors should know what is happening.

Recruiters should know their contractors are being supported.

And nobody should need a detective board and three red strings to understand a payslip.

Reason Five: Good Customer Service Is Part of Payroll

Payroll technology is useful.

Portals are useful.

Processes are useful.

But sometimes you just need a person who understands the problem and can help fix it.

That is why customer service remains such a big part of Sterling’s proposition.

Our UK-based support team currently resolves 92% of queries on first contact.

That matters because payroll queries are rarely something people want to revisit six times.

If a contractor has a question about their pay, they want an answer.

If an agency needs support, they want somebody to take ownership.

If something needs resolving, everyone wants it resolved.

Good customer service should not sit beside payroll as an optional bonus.

It is part of delivering payroll properly.

Reason Six: Technology Should Make Things Simpler

Technology in payroll should remove friction.

Not add another password, another portal, and another reason to shout at a laptop.

At Sterling, our technology is designed around the people actually using it.

That means helping contractors access information more easily and helping processes run more smoothly.

The aim is not technology for the sake of technology.

It is clarity.

Visibility.

Less chasing.

Fewer unnecessary questions.

And more time for everyone to focus on what they are actually there to do.

Very futuristic.

Almost suspiciously sensible.

Reason Seven: We Understand the Recruitment Industry

A payroll provider can understand payroll without necessarily understanding recruitment.

There is a difference.

Recruitment moves quickly.

New contractors onboard.

Assignments change.

Timesheets arrive.

Questions come in.

Clients have expectations.

Recruiters need answers.

Your payroll partner needs to understand that pace.

With 27 years of experience, Sterling has built its service around the realities of working with recruitment agencies and contractors.

That means understanding that payroll is not operating in isolation.

It sits inside a much wider relationship.

And the better your payroll partner understands that relationship, the easier it becomes to support everyone involved.

What Should You Expect From a Payroll Partner?

National Payroll Week is a good opportunity to ask whether your current provider is genuinely helping your agency.

A strong payroll partner should help you answer yes to questions like these:

• Are contractors paid accurately and consistently?
• Is onboarding straightforward?
• Can contractors access support easily?
• Are compliance processes clear and demonstrable?
• Does your agency have a reliable point of contact?
• Is payroll reducing administration or adding to it?
• Are problems dealt with quickly?
• Do you feel confident recommending the provider to contractors and clients?

If those questions are difficult to answer, your payroll relationship might deserve a closer look.

Because payroll should support your business.

Not create a weekly obstacle course.

Compliant. Reliable. Trusted.

National Payroll Week might put payroll centre stage for a few days.

At Sterling, it stays centre stage all year.

Because behind every successful payment is a contractor relying on it.

Behind every contractor is an agency whose reputation matters.

And behind every strong agency partnership should be systems, processes, people, and support you can trust.

That is what Sterling brings to the table.

Compliant payroll solutions.

Reliable weekly processing.

Dedicated agency account management.

Contractor-first support.

Transparent communication.

Experienced people.

And a service built around making payroll simpler for everyone involved.

Payroll might not always get the applause.

We are fine with that.

We would rather it simply works.

Every week.

FAQs

Why is National Payroll Week important?

National Payroll Week celebrates the role payroll professionals play in keeping businesses and workers moving. For recruitment agencies, it is also a useful opportunity to review how effectively payroll supports contractors, internal teams, compliance, and client relationships.

What should recruitment agencies look for in a payroll partner?

Agencies should consider compliance, payroll accuracy, contractor support, onboarding, communication, account management, and how much administration the relationship creates. A good payroll provider should make the process easier for both agencies and contractors.

Why does payroll affect contractor experience?

Contractors rely on clear onboarding, accurate payments, understandable information, and responsive support. Poor payroll experiences can quickly affect their perception of the recruitment agency that introduced the provider.

Does The Sterling Group support both Umbrella and CIS payroll?

Yes. The Sterling Group provides compliant umbrella payroll and CIS solutions, allowing agencies to work with an experienced partner across different contractor arrangements.

What makes Sterling different from other payroll providers?

Sterling combines 27 years of experience with FCSA approval, Workforce Assured accreditation across key Sterling companies, dedicated agency support, a UK-based customer service team, contractor technology, and a strong focus on compliance, reliability, and transparency.

Because payroll is too important to become the problem everyone is talking about.

Choosing a payroll partner is no longer just about finding someone who can process payments on time.

For recruitment agencies, the wrong umbrella or CIS provider can create unnecessary administration, contractor complaints, compliance concerns, and reputational risk. The right partner should do the opposite. They should make payroll easier to manage, improve the contractor experience, and give your agency confidence that the processes behind every payment stand up to scrutiny.

That means agencies need to look beyond surface-level promises.

A compliant payroll partner should be able to demonstrate strong processes, reliable weekly payroll, transparent communication, responsive support, and a genuine understanding of UK payroll legislation.

At The Sterling Group, we believe agencies should expect more from their payroll provider.

Here is what to look for when choosing a compliant payroll partner.

Why Choosing a Compliant Payroll Partner Matters

Payroll sits much closer to your agency reputation than it may initially appear.

When a contractor has a poor payroll experience, they rarely see it as an isolated issue with a third-party provider. They associate that experience with the agency that introduced them.

Late payments, confusing deductions, poor communication, difficult onboarding, or unresolved queries can quickly affect contractor confidence.

The same applies to clients.

Agencies need to know that the suppliers operating within their labour supply chain are working to appropriate standards and following robust processes.

A strong payroll partner can help your agency:

Reduce internal administration

Improve contractor satisfaction

Strengthen compliance processes

Protect your reputation

Support stronger client relationships

Create a more consistent contractor journey

The relationship should therefore be treated as a genuine partnership rather than simply another outsourced service.

1. Compliance Should Be Demonstrable, Not Assumed

Every payroll provider can say they take compliance seriously.

The more important question is whether they can demonstrate it.

Recruitment agencies should look for payroll partners that can explain their processes clearly, provide evidence where appropriate, and show that compliance is built into the way they operate.

That includes areas such as payroll procedures, onboarding, record keeping, contractor communication, and an understanding of current UK payroll legislation.

Independent standards and accreditations can also help agencies assess whether a provider’s claims are backed by external scrutiny.

The Sterling Group is FCSA approved, and Sterling Solutions Umbrella Limited, Sterling Solutions Rail Limited and Sterling CIS Limited have achieved Workforce Assured accreditation.

These standards provide additional evidence of the systems, processes, and controls operating behind the service.

For agencies reviewing suppliers or Preferred Supplier Lists, this matters.

Compliance should never rely entirely on trust.

There should be proof behind it.

2. Reliable Payroll Is Non-Negotiable

Payroll is one of those services that becomes extremely noticeable when something goes wrong.

Contractors expect to be paid correctly and on time. Agencies expect payroll to run smoothly without creating unnecessary queries or additional workload.

That is why reliability needs to be one of the first things an agency considers when choosing a payroll provider.

Look at how the provider manages:

Weekly payroll processing

Timesheet deadlines

Contractor information

Payroll queries

Escalations

Communication when issues arise

The Sterling Group provides fast and accurate weekly payroll processing across its umbrella and CIS services, supported by teams who understand the importance of consistency.

Reliability is not about performing well during an easy payroll week.

It is about maintaining the same standard week after week.

That consistency helps contractors feel confident in their pay and gives agencies one less operational issue to manage.

3. Look at the Contractor Experience

A payroll provider can meet its basic obligations and still deliver a frustrating contractor experience.

That should matter to recruitment agencies.

Contractors interact directly with the provider through onboarding, payroll, documentation, queries, and ongoing support. Every one of those interactions contributes to their perception of the wider recruitment process.

Good contractor support should therefore include:

Simple onboarding

Clear explanations

Transparent communication

Easy access to account information

Responsive support when questions arise

The Sterling Contractor Portal allows contractors to view their account information at any time, giving them greater visibility without needing to rely on their recruiter for routine information.

Clearer access can reduce uncertainty and prevent simple questions from becoming unnecessary problems.

A positive contractor experience also benefits agencies.

When contractors feel informed and supported, there are fewer frustrations for recruiters to manage and a stronger relationship between everyone involved.

4. A Good Payroll Partner Should Reduce Your Administration

Outsourcing payroll should reduce workload.

If your internal team spends significant time answering payroll questions, chasing information, resolving onboarding problems, or escalating contractor issues, something is not working properly.

A payroll partner should make the process easier for your recruitment consultants and operations teams.

That means providing:

Straightforward onboarding

Dedicated agency support

Clear communication routes

Reliable payroll processes

Responsive issue resolution

The Sterling Group provides dedicated agency account management, giving recruitment teams a clear point of contact when support is needed.

That matters because communication becomes much easier when everyone knows where responsibility sits.

Rather than recruiters being passed between departments or chasing multiple contacts, there should be a clear route to resolution.

Less administration means your team can spend more time on recruitment and less time troubleshooting payroll.

5. Transparency Should Run Through the Whole Relationship

Transparency is often discussed in relation to contractor payslips and deductions.

But for recruitment agencies, transparency needs to go further.

Your payroll provider should be clear about how its processes work, what contractors are told, who handles different queries, and what happens if an issue needs escalating.

Agencies should never feel like payroll disappears into a black box once a contractor has been referred.

Clear communication creates confidence.

Contractors know what is happening with their pay.

Recruiters know where to direct questions.

Agency teams know who owns an issue.

Clients know the supply chain is being managed responsibly.

That clarity helps prevent small misunderstandings from becoming bigger problems.

At Sterling, transparency is part of how we approach both contractor support and agency relationships.

Good payroll should not require guesswork.

6. Ask What Happens When Something Goes Wrong

The real quality of customer service is rarely tested when everything is running perfectly.

It becomes obvious when something needs fixing.

Payroll is time-sensitive. A contractor asking about a payment, timesheet, onboarding requirement, or payslip often needs a clear answer quickly.

That is why agencies should ask potential payroll partners how they manage problems.

Questions worth asking include:

Who handles contractor queries?

Does the agency have a dedicated contact?

What is the escalation process?

How quickly are queries normally resolved?

Will contractors speak to someone who understands the issue?

The Sterling Group has a UK-based support team and currently resolves 92% of queries on first contact.

That figure reflects something we believe strongly.

Customer service should not simply acknowledge a problem.

It should help solve it.

Strong support protects the contractor experience and reduces the number of problems that eventually make their way back to recruitment consultants.

7. Consider the Wider Partnership

The best payroll relationships go beyond payroll processing.

A strong provider should understand how their service affects your recruitment business.

That includes contractor satisfaction, client confidence, internal efficiency, compliance, and reputation.

For agencies, the wider benefits of choosing the right partner can include:

Greater operational efficiency

Reduced administration

Improved contractor satisfaction

Stronger client relationships

Better supply chain confidence

Increased trust in your agency

This is particularly important when reviewing a Preferred Supplier List.

A PSL should not simply be a list of providers that technically meet minimum requirements.

It should be made up of partners that strengthen the service your agency provides.

When contractors are supported properly, payroll is reliable, and communication is clear, the relationship reflects well on everyone involved.

Questions to Ask a Potential Umbrella or CIS Payroll Partner

1. What evidence supports your compliance claims?

Look beyond statements on a website. Ask about independent standards, accreditations, processes, and how compliance is monitored.

2. How do you stay up to date with UK payroll legislation?

Your provider should have clear expertise in UK payroll requirements and be able to explain relevant changes in plain English.

3. What support does our agency receive?

Find out whether you will have a dedicated contact and what happens if an issue needs escalation.

4. What does contractor onboarding look like?

The process should be clear, consistent, and easy for contractors to understand.

5. What information can contractors access themselves?

Self-service portals and clear documentation can help reduce unnecessary queries.

6. How are payroll queries handled?

Ask who owns contractor questions, how quickly they are normally dealt with, and whether your agency needs to become involved.

7. How do you reduce administration for recruiters?

A good provider should remove work from your team rather than create more of it.

8. What happens when something goes wrong?

Good providers should have clear processes for taking ownership, communicating updates, and resolving problems.

Compliant. Reliable. Trusted.

For recruitment agencies, choosing a payroll provider is ultimately about confidence.

Can you trust the provider’s compliance processes?

Can contractors rely on their payroll?

Will your team receive responsive support?

Will the relationship reduce administration rather than add to it?

And will the provider strengthen the experience your agency offers contractors and clients?

Those are the standards agencies should be measuring.

At The Sterling Group, our umbrella and CIS services are built around compliant processes, reliable payroll, transparent communication, contractor support, and dedicated agency account management.

Because good payroll should do more than process payments.

It should support your people, protect your reputation, and make your agency easier to run.

FAQs

How do recruitment agencies choose a compliant umbrella company?

Agencies should look at more than price or headline claims. A strong umbrella partner should be able to demonstrate robust compliance processes, clear contractor communication, reliable payroll, responsive support, and appropriate independent standards or accreditations. Agencies should also consider how the provider supports contractors and how much administration the relationship creates internally.

What should an agency check before adding an umbrella company to its PSL?

Review compliance standards, onboarding processes, payroll reliability, contractor support, communication routes, escalation procedures, and the provider’s ability to explain its processes clearly. The strongest PSL partners should help protect your agency’s reputation while improving the contractor experience.

Why does contractor experience matter when choosing a payroll provider?

Contractors often associate their payroll experience with the recruitment agency that referred them. Poor onboarding, confusing communication, or unresolved payroll queries can therefore affect the agency relationship. Choosing a provider that supports contractors properly can improve satisfaction and reduce the number of problems recruiters need to manage.

What makes a payroll provider reliable?

Reliability means accurate and consistent payroll processing, clear communication, strong processes, accessible support, and ownership when an issue needs resolving. It is not simply about getting payroll right once. It is about maintaining that standard week after week.

Can one payroll partner support both umbrella and CIS contractors?

The Sterling Group provides both umbrella payroll and CIS support, allowing agencies to work with a partner that understands different contractor arrangements while maintaining a consistent focus on compliance, communication, and service.

Workforce Assured Accreditation: Why Agencies Need Evidence of ComplianceEvery payroll provider can say it takes compliance seriously. The more important question is whether it can prove it.

For recruitment agencies, supplier compliance is no longer something that can be assessed through reassuring conversations, polished policies or a logo on a website. Agencies need evidence that the businesses within their labour supply chains have the right systems, controls and governance in place.

This matters even more following the introduction of new PAYE rules for labour supply chains involving umbrella companies. From 6 April 2026, an agency with the direct contract to supply a worker to an end client can be held responsible where the correct PAYE has not been paid by an umbrella company.

Due diligence must therefore go further than taking a provider’s claims at face value.

Workforce Assured accreditation supports this shift towards evidence-led compliance. It provides independent recognition that a provider has been assessed against a standard designed around temporary labour and employment practices.

For agencies choosing payroll partners, that independent assessment can provide something increasingly valuable: confidence supported by evidence.

Why compliance claims are no longer enough

Most payroll and workforce providers use similar language.

They talk about trust, transparency, accurate payroll and robust compliance. Those principles matter, but the words alone reveal very little about how the provider operates behind the scenes.

A provider may have policies in place, but are those policies followed consistently? Are its systems subject to proper oversight? Can it demonstrate how workers are engaged and paid? Would its records and processes stand up to external scrutiny?

These are the questions agencies now need to ask.

HMRC advises employment businesses to carry out due diligence before using an umbrella company. Its guidance recommends identifying every business within the labour supply chain, understanding how workers are engaged and checking that PAYE is being operated correctly.

The new PAYE rules have increased the commercial importance of these checks. Where an umbrella company fails to account for the correct PAYE, HMRC can recover the amount from the responsible agency or, where no agency is involved, the end client.

Compliance claims may begin the conversation, but they cannot finish it.

Agencies need evidence that supports the promises being made.

What is Workforce Assured accreditation?

Workforce Assured is an accreditation focused on temporary labour and employment practices within the built environment.

It is designed to support legal compliance, good governance and better employment practices across labour supply chains. The accreditation provides independent recognition that a business has been assessed against a compliance-focused standard.

Workforce Assured was launched with support from leading UK construction contractors to raise standards around how companies recruit, engage and pay their workforces.

This makes the accreditation particularly relevant to recruitment agencies, contractors, payroll intermediaries and end clients operating within construction and related sectors.

Rather than relying entirely on a provider’s own description of its standards, agencies can see that an independent organisation has examined the business against defined expectations.

Accreditation does not remove the need for an agency’s own supplier checks. It should instead form part of a broader due diligence process, providing another meaningful source of evidence.

How Workforce Assured supports evidence-led due diligence

Strong due diligence is not a single form completed when a new provider joins a Preferred Supplier List.

It is an ongoing process of understanding who is within the labour supply chain, how each organisation operates and whether the appropriate controls remain in place.

Workforce Assured accreditation can strengthen this process in several ways.

Independent assessment

Self-assessment has limitations. A provider reviewing its own standards may have good intentions, but it cannot offer the same objectivity as an external assessment.

Independent accreditation introduces another level of scrutiny. It demonstrates that the provider has been prepared to open its processes to review rather than asking agencies simply to accept its assurances.

Defined standards

Vague commitments are difficult to measure.

An accreditation framework provides defined expectations against which a provider can be assessed. This helps move supplier conversations away from broad promises and towards systems, controls and evidence.

Stronger procurement decisions

When agencies compare potential payroll providers, price and speed should not be the only deciding factors.

Accreditation can help procurement and compliance teams identify providers that have made a demonstrable investment in responsible employment practices and supply chain governance.

Better client conversations

Agencies are increasingly expected to explain how they select and oversee their payroll partners.

Being able to reference independent accreditation can support discussions with end clients, particularly where those clients have strict procurement, governance or labour compliance requirements.

It gives the agency more than a verbal assurance to pass along the supply chain.

Why evidence matters under the PAYE rules introduced in April 2026

The PAYE rules for labour supply chains involving umbrella companies changed on 6 April 2026.

Where workers are supplied through an umbrella company, the agency holding the contract with the end client is responsible for making sure PAYE is operated correctly. If HMRC finds that the umbrella company has not paid the correct PAYE, it can recover the unpaid amount from that agency.

Where there is no recruitment agency in the supply chain, that responsibility sits with the end client.

The umbrella company remains responsible for calculating PAYE correctly and paying HMRC. However, the consequences of a failure can now travel further through the supply chain.

This makes supplier selection a financial and commercial risk decision, not simply an administrative one.

Agencies need to know:

• Who is employing and paying each worker
• Whether additional businesses appear within the payment chain
• How PAYE calculations and payments are controlled
• What information the provider will supply for verification
• Whether processes are documented and consistently followed
• What independent evidence supports the provider’s claims

Workforce Assured accreditation cannot replace these checks. No single accreditation should be treated as a shortcut around proper due diligence.

It can, however, contribute useful independent evidence that a provider takes governance, compliance and responsible workforce practices seriously.

What should agencies ask their payroll providers?

A credible provider should be comfortable answering detailed questions.

Agencies reviewing an existing supplier or considering a new payroll partner should ask for practical evidence, not simply a standard sales presentation.

Useful questions include:

• Which legal entity will employ or engage the worker?
• Will any other businesses be involved in the payment chain?
• How does the provider calculate and report PAYE?
• What controls are used to identify payroll errors?
• How are compliance responsibilities assigned internally?
• How often are policies and procedures reviewed?
• What documents can the provider supply to support agency checks?
• Has the business been independently assessed or accredited?
• What happens when an issue or discrepancy is identified?
• How will the provider support ongoing monitoring?

The quality of the response matters as much as the answer itself.

Clear documentation, transparent processes and a willingness to provide evidence indicate a very different compliance culture from vague assurances or defensive answers.

A reliable partner should make due diligence easier, not treat it as an inconvenience.

Accreditation should support due diligence, not replace it

Independent accreditation is valuable, but agencies should avoid treating any badge as a complete compliance strategy.

A strong approach combines several layers of scrutiny.

This may include:

• Verifying company and legal entity details
• Mapping the complete labour supply chain
• Reviewing contracts and employment documentation
• Checking relevant insurance
• Examining sample payroll records and payslips
• Understanding how tax and National Insurance are handled
• Confirming how workers receive support
• Reviewing independent accreditations
• Repeating checks at suitable intervals
• Recording findings and actions clearly

This distinction is important.

Evidence-led due diligence does not mean collecting certificates and storing them in a folder. It means understanding what those certificates represent, combining them with direct checks and continuing to monitor the relationship.

Workforce Assured accreditation is most useful when it forms part of that wider process.

What Sterling’s Workforce Assured accreditation demonstrates

Sterling Solutions Umbrella Limited, Sterling Solutions Rail Limited and Sterling CIS Limited have achieved Workforce Assured accreditation.

For The Sterling Group, this is not simply a marketing statement. It provides independent recognition of the systems, controls and standards that sit behind our services.

It demonstrates our willingness to have those standards examined rather than asking agencies and clients to rely solely on what we say about ourselves.

That distinction matters.

Recruitment agencies need payroll partners that understand the pressure they face. They must protect workers, meet client expectations, maintain clear records and manage an increasingly complex compliance environment.

Our Workforce Assured accreditation supports the evidence agencies need when assessing their supply chain. It sits alongside our commitment to clear communication, accountable processes and doing things properly at every stage of the contractor journey.

The commercial value of choosing partners that can provide evidence

Compliance failures rarely remain confined to the payroll department.

They can lead to financial exposure, disrupted contractor relationships, difficult client conversations and damage to an agency’s reputation.

The reverse is also true.

A well-managed and transparent payroll partnership can support:

• Stronger contractor confidence
• More effective client procurement conversations
• Clearer audit trails
• Fewer surprises within the supply chain
• Better-informed supplier decisions
• Greater confidence when reviewing a PSL

Evidence gives agencies a firmer foundation for those decisions.

It helps compliance teams demonstrate why a provider was selected. It allows account teams to answer client questions more confidently. It also shows contractors that the businesses responsible for their employment and pay have been chosen carefully.

That is why independently assessed standards matter commercially, not only operationally.

Frequently asked questions

What does Workforce Assured accreditation mean?

Workforce Assured accreditation provides independent recognition that an organisation has been assessed against a standard focused on temporary labour and employment practices. It is intended to support legal compliance, governance and better practices within labour supply chains.

Does Workforce Assured accreditation replace agency due diligence?

No. Agencies should continue to carry out their own checks on umbrella companies and other labour supply chain partners. Accreditation can provide valuable supporting evidence, but it should form part of a wider, ongoing due diligence process.

Why is Workforce Assured relevant to recruitment agencies?

Recruitment agencies need to understand how workers are engaged and paid throughout their supply chains. Workforce Assured accreditation gives agencies additional independent evidence when assessing the standards, governance and compliance approach of a potential partner.

Can an agency be liable for unpaid PAYE?

Under the rules in force from 6 April 2026, the agency with the direct contract to supply a worker to the end client is responsible for making sure the umbrella company operates PAYE correctly. HMRC can recover unpaid PAYE from that agency where the umbrella company has failed to pay the correct amount.

Which Sterling companies are Workforce Assured accredited?

Sterling Solutions Umbrella Limited, Sterling Solutions Rail Limited and Sterling CIS Limited have achieved Workforce Assured accreditation.

Choose compliance that can be evidenced

Agencies should not have to choose payroll partners based on promises alone.

In a market where responsibility is increasing and supplier decisions can carry significant financial and reputational consequences, evidence matters.

Workforce Assured accreditation gives agencies another independent source of confidence when assessing payroll and workforce providers. It shows that compliance standards have been opened to scrutiny and assessed against defined expectations.

It is not a replacement for robust due diligence. It is evidence that can make that due diligence stronger.

The Sterling Group is proud to be Workforce Assured accredited and to give agencies greater confidence in the processes behind our umbrella, rail and CIS services.

To discuss your current payroll arrangements, review your Preferred Supplier List or learn more about our Workforce Assured accreditation, contact The Sterling Group.

A preferred supplier list should do more than organise approved providers. For recruitment agencies, it should reduce risk, protect contractor experience, support compliance, and give internal teams confidence in the partners they are recommending.

The problem is that too many PSLs are built around habit. Familiar names. Historic relationships. Providers that have “always been there”. That may feel convenient, but convenience is not the same as control.

In a market where payroll compliance, transparency, and contractor expectations are under increasing scrutiny, agencies need more than a list of umbrella companies. They need evidence that those suppliers are operating properly, communicating clearly, and supporting workers in a way that reflects well on the agency.

That is where a proof-led approach matters.

What is a preferred supplier list?

A preferred supplier list, often shortened to PSL, is a list of approved suppliers that an agency recommends or allows contractors to use.

In recruitment, this often includes umbrella payroll providers, outsourced PAYE providers, compliance partners, and other businesses involved in supporting contractors. The purpose is simple: to give the agency and its contractors a controlled, reliable group of suppliers to work with.

A strong preferred supplier list helps agencies:

• Choose partners that meet clear standards
• Reduce compliance and reputational risk
•  Improve consistency across contractor onboarding
• Give contractors clearer choices
• Create a more reliable process for internal teams

The issue is not whether agencies should have a PSL. Most should. The real question is whether that PSL is actively protecting the business or simply sitting there as an admin document.

A good PSL should be reviewed, challenged, and strengthened over time. It should reflect current risk, current legislation, current contractor expectations, and current standards across the umbrella payroll market.

If it does not, it can create a false sense of security.

Why PSLs matter more than ever for recruitment agencies

Recruitment agencies operate in a supply chain where decisions do not stay isolated. The umbrella company a contractor uses can affect payroll accuracy, tax compliance, onboarding speed, worker confidence, and the agency’s reputation.

When payroll goes wrong, contractors rarely see it as “just a supplier issue”. They often associate the experience with the agency that introduced or approved the provider.

That is why PSL decisions matter.

A weak PSL can lead to:

• Confused contractors
• Slow onboarding
• Unclear deductions
• Payment queries
• Compliance concerns
• Reputational damage
• More pressure on recruitment consultants and support teams

A strong PSL does the opposite. It gives agencies a clearer framework for who they work with, why they work with them, and what standards those suppliers must maintain.

This is especially important as expectations around umbrella payroll continue to rise. Agencies are being asked to show stronger due diligence, clearer processes, and better supply chain awareness. Contractors also expect more transparency around their pay, deductions, holiday pay, and employment rights.

A PSL should sit at the centre of that control.

Not as a tick-box exercise. As a working part of the agency’s risk and contractor experience strategy.

The problem with a PSL that only looks compliant

Some PSLs look organised on the surface. There may be a list of supplier names, a few approval dates, and some historic checks in a folder somewhere.

But looking compliant is not the same as being protected.

The real value of a preferred supplier list comes from the quality of the checks behind it and the standards suppliers continue to meet after they are approved.

An agency should be asking:

1. When was each supplier last reviewed?
2. What evidence supports their approval?
3. How do they handle contractor queries?
4. What systems support payroll transparency?
5. Can they evidence compliance, not just claim it?
6. Do contractors receive clear explanations of deductions?
7. Are onboarding and support processes consistent?
8. Does the supplier strengthen or weaken the agency’s reputation?

The risk with a passive PSL is that it can become outdated quickly. A supplier that looked suitable two years ago may no longer meet the standards the agency needs today.

That is why agencies should avoid building PSLs around assumptions. “We have used them for years” is not enough. “They are well known” is not enough. “No one has complained loudly yet” is definitely not enough.

A PSL should be built on evidence, not comfort.

What agencies should look for in a PSL partner

When reviewing an umbrella payroll provider for a preferred supplier list, agencies should look beyond basic service claims.

Every supplier can say they are compliant. Every supplier can say they care about contractors. The difference is whether they can demonstrate it in the way they operate.

A strong PSL partner should be able to show:

• Clear compliance processes
• Transparent payroll information
• Reliable communication
• Accessible contractor support
• Fast, consistent onboarding
• Documented procedures
• Strong industry credentials
• Technology that improves visibility
• A service model that reduces admin rather than adding to it

This is where the conversation needs to move from “Can this provider process payroll?” to “Can this provider protect our agency and support our contractors properly?”

For agencies, a supplier is not just a back-office choice. It becomes part of the contractor journey. If the supplier is difficult to reach, slow to respond, vague about deductions, or inconsistent with documentation, that friction often lands back with the agency.

The best PSL partners make life easier for everyone involved. They help consultants focus on placements, give contractors confidence in their pay, and give leadership teams a stronger grip on compliance and reputation.

Sterling’s approach is built around that kind of partnership. It combines compliant payroll, UK-based support, in-house technology, contractor-first service, and visibility through veriPAYE.

Where Workforce Assured status strengthens agency confidence

Workforce Assured status adds an important layer to the PSL conversation because it gives agencies another proof point when reviewing supplier standards.

For agencies, external recognition and independent assurance matter. They help move the discussion away from vague supplier promises and towards evidence that a provider has been assessed against meaningful expectations.

That matters because PSL decisions need to stand up to scrutiny.

When an agency chooses an umbrella payroll partner, it is trusting that provider with contractor pay, employment processes, communication, and compliance-sensitive information. If something goes wrong, the impact can travel quickly across the contractor relationship and the agency’s brand.

Workforce Assured status supports agency confidence because it shows a commitment to high standards, responsible processes, and ongoing accountability.

It should not be the only factor in a PSL decision, but it should form part of the wider evidence picture. Alongside credentials such as FCSA approval, strong service performance, proven contractor support, and transparent technology, it helps agencies make better informed choices.

The message is simple: a PSL should not depend on trust alone.

Trust is important, but it is stronger when it is backed by proof.

How veriPAYE adds transparency to the payroll process

Payroll transparency is one of the most important parts of a strong PSL.

Contractors want to understand what they are being paid, what deductions have been made, and why those deductions appear on their payslip. Agencies want confidence that payroll is being handled properly, with the right checks and visibility behind the process.

That is why Sterling’s partnership with veriPAYE fits naturally into a proof-led PSL strategy.

veriPAYE supports greater transparency by helping agencies and contractors gain clearer visibility across payroll information and compliance processes. It strengthens confidence because it gives people more than verbal reassurance. It supports the idea that payroll should be clear, traceable, and easier to understand.

For agencies, that can reduce uncertainty. For contractors, it can reduce confusion. For both, it helps create a smoother working relationship.

The important point is that technology should never replace service. It should support it.

At Sterling, veriPAYE sits alongside a UK-based support team, contractor-focused systems, and a service model built around clarity, confidence, and consistency. That combination matters because payroll is not just data. It is people’s income, people’s questions, and people’s trust.

When used properly, technology gives structure to that trust.

Why contractor experience belongs in every PSL decision

A PSL is often discussed as a compliance tool, but it is also a contractor experience tool.

That matters because contractors judge agencies by the full journey, not just the role they are placed into. If onboarding is clunky, payroll is confusing, or support is hard to reach, the overall experience suffers.

Even if the issue sits with an umbrella provider, the contractor may still connect that frustration to the agency.

That is why contractor experience should be part of every PSL review.

The best PSL partners understand that their role is not just to process payments. It is to support confidence.

For contractors, that means knowing what is happening with their pay and having someone to speak to when questions come up. For agencies, it means fewer escalations, fewer repeated queries, and stronger trust across the contractor relationship.

This is where Sterling’s service-led approach is important. With UK-based support, a contractor app, continuity of employment support, and in-house technology built around contractor needs, the aim is to make the experience clearer and more reliable from the start.

A strong PSL should not just protect the agency from risk. It should help contractors feel properly supported.

Building a PSL that protects your agency and your contractors

The strongest preferred supplier lists are built with intention.

They are not just lists of names. They are frameworks for better decision-making.

A modern PSL should help agencies answer three important questions:

Are our suppliers compliant and able to evidence their standards?
Do our suppliers give contractors a clear, reliable experience?
Can our team confidently explain why these providers are approved?

If the answer to any of those questions is uncertain, it may be time to review the list.

A proof-led PSL should bring together compliance, transparency, service, and accountability. It should include partners who can show how they work, explain their processes clearly, and support both the agency and the contractor when it matters.

Sterling brings together several key proof points for agencies reviewing their PSL:

• 27 years of industry experience
• FCSA approval
• Workforce Assured status
• veriPAYE partnership
• UK-based support
• In-house technology
• Contractor app support
• Continuity of employment support
• A service-led approach built around clarity, confidence, and consistency

For agencies, this means more than adding another name to a supplier list. It means choosing a partner that understands the commercial importance of payroll, the pressure on recruitment teams, and the expectations contractors now have.

A PSL should make your agency stronger.

It should reduce uncertainty, improve contractor trust, and give your team confidence that the providers you recommend are doing things properly.

That is the standard worth building around.

FAQs

What is a preferred supplier list in recruitment?

A preferred supplier list is a group of approved suppliers that an agency works with or recommends to contractors. In recruitment, this often includes umbrella payroll providers. The aim is to create a controlled list of trusted partners who meet the agency’s standards for compliance, service, communication, and contractor support.

Why do recruitment agencies use PSLs?

Recruitment agencies use PSLs to reduce risk, improve consistency, and give contractors access to approved providers. A strong PSL helps agencies manage supplier quality, support compliance, and protect their reputation. It also makes it easier for internal teams to recommend providers with confidence.

What should agencies check before adding an umbrella company to a PSL?

Agencies should check compliance credentials, service standards, payroll transparency, onboarding processes, contractor support, and evidence of ongoing performance. Approval should not be based on claims alone. A good umbrella provider should be able to show how they operate and how they protect both contractors and agencies.

How does payroll transparency support PSL compliance?

Payroll transparency helps agencies and contractors understand how pay is calculated, what deductions are made, and where information can be evidenced. This reduces confusion and supports stronger confidence in the process. Tools such as veriPAYE can help provide greater visibility and assurance across payroll activity.

Can contractors request to use Sterling if an agency has a PSL?

In many cases, contractors can ask their agency whether Sterling can be used or added as an approved provider. Agencies reviewing their PSL can speak to Sterling about compliant payroll, contractor support, continuity of employment, veriPAYE-backed visibility, and how Sterling can support a stronger supplier framework.

Review your PSL with confidence

Your preferred supplier list should do more than sit in a folder.

It should protect your agency, support your contractors, and give your team confidence that the partners you work with are clear, compliant, and reliable.

If you are reviewing your PSL, The Sterling Group can help you build confidence through compliant payroll, contractor-first support, Workforce Assured status, FCSA approval, veriPAYE-backed transparency, and 27 years of proven standards.

At the Core of The Sterling Group

In an industry where trust, accuracy and service matter every single day, what sits at the core of your payroll partner makes all the difference.

At The Sterling Group, that core is built around more than processes and systems. It is shaped by the values that guide the business, the people behind the service, and a commitment to doing things properly. From supporting contractors to working closely with agencies, everything Sterling does is grounded in a clear purpose: to deliver a service that is reliable, professional and built around people.

Because while payroll, compliance and technology are all essential, it is the way those things come together that defines the experience clients and contractors receive.

People at the heart of everything

At The Sterling Group, people are not an afterthought. They are at the centre of the business.

That means creating an environment where employees feel valued, motivated and empowered, while also making sure contractors and clients receive the same level of care and attention. Strong relationships are built on more than a service agreement. They are built on communication, support and consistency.

Sterling’s values reflect that approach. Being open, honest and respectful to all is not simply a statement on a wall. It is part of the day-to-day standard the team works to. Whether that is answering a contractor query, supporting an agency partner or helping someone navigate a process with confidence, every interaction matters.

The value “You Count” captures this perfectly. Everything the team does has an impact, and those small moments of support, clarity and responsiveness are often the things people remember most.

Accountability in action

In a compliance-focused sector, accountability is not optional. It is essential.

At The Sterling Group, accountability means taking ownership, maintaining high standards and doing things the right way, even when no one is looking. It is a value that runs through every part of the business and supports the confidence that clients place in the service.

As an FCSA Accredited provider, Sterling understands the importance of compliance not as a box-ticking exercise, but as a core part of protecting agencies, contractors and the wider supply chain. In a landscape where legislation and scrutiny continue to evolve, working with a partner that takes responsibility seriously matters more than ever.

This commitment is also reflected in Sterling’s partnership with veriPAYE, helping agencies strengthen their compliance processes and make informed decisions with greater confidence. It is part of a wider approach that puts integrity, transparency and accountability at the forefront.

Because when standards are built into the foundation, clients can move forward with greater peace of mind.

Progress that supports people

Technology has an important role to play in modern payroll and contractor support, but only when it genuinely improves the experience for the people using it.

At The Sterling Group, innovation is not about adding complexity for the sake of it. It is about creating practical solutions that make life easier. With an in-house tech team and a contractor app designed to support the end user, Sterling continues to invest in tools that improve accessibility, efficiency and convenience.

This is where values such as leadership, motivation and “You Count” come into play again. Sterling is committed to driving positive change, embracing smarter ways of working and continually looking for ways to improve the service it offers. That progress is not pursued for appearances. It is pursued because people’s time, experience and trust matter.

Good technology should support people, not replace them. It should remove friction, increase transparency and help make everyday processes feel simpler. That is the kind of progress Sterling believes in.

A culture that builds trust

Trust is not built through big promises alone. It is built through consistency.

It comes from doing what you say you will do, taking pride in your work and showing up with the same level of care every day. At The Sterling Group, that culture is shaped by values that encourage the team to be accountable, motivated and open in the way they work.

There is also something important to be said for enjoying what you do. A team that takes pride in its work and feels motivated to do its best will always bring more energy, more care and more commitment to the service it provides. That sense of pride is part of what helps Sterling build strong, lasting relationships with agencies and contractors alike.

It is also reflected in the reputation the business continues to build. Positive client feedback and five-star Trustpilot reviews do not happen by accident. They are the result of a team that understands that trust is earned, not assumed.

More than a service

At its core, The Sterling Group is about more than payroll.

It is about people, accountability, integrity and progress. It is about creating a business where employees feel empowered, where contractors feel supported, and where clients know they are working with a partner they can rely on.

These values shape the way Sterling works every day, from customer service and compliance to technology and long-term relationships. And in an industry where the details matter, that kind of foundation makes all the difference.

Because when the core is strong, everything built on it is stronger too.

 

At The Sterling Group, compliance has always been more than a requirement. It is a core part of how we operate, how we support our partners and how we build trust across the labour supply chain.

That is why we are proud to announce that Sterling Solutions Umbrella Limited, Sterling Solutions Rail Limited and Sterling CIS Limited have successfully achieved Workforce Assured accreditation.

This is a milestone we are incredibly proud of. It independently demonstrates our firm commitment to the highest standards of compliance for both employees and self-employed contractors, while strengthening our position as a trusted, compliant umbrella and self-employed solution for agencies and end clients alike.

In an increasingly regulated environment, confidence, transparency and reduced risk matter more than ever. Achieving Workforce Assured accreditation provides additional independent confirmation that our systems, controls and processes are robust, compliant and aligned with current legislative guidelines.

This is particularly important in light of the Joint and Several Liability changes, which came into force on 6 April 2026. HMRC’s new PAYE rules for labour supply chains that include umbrella companies place increased emphasis on supply chain transparency, lawful workforce practices and due diligence across the chain.

For us, this accreditation reflects the standards we have been working towards and the compliance-first approach that has always shaped our business.

What is Workforce Assured accreditation?

Workforce Assured describes its accreditation as a standard for temporary labour and employment practices for the built environment, designed to support legal compliance, governance and best practice across labour supply chains. It is intended to give businesses and their supply-chain partners greater confidence that the right systems, controls and processes are in place.

In simple terms, Workforce Assured accreditation provides independent recognition that a business has been assessed against a compliance-focused standard.

That matters because in today’s market, saying the right things is not enough. Agencies and clients want reassurance that the businesses they work with are backed by robust processes, clear governance and a genuine commitment to doing things properly.

For The Sterling Group, this is exactly why the accreditation matters. Compliance has never been an afterthought for us. It has always been built into the way we work, the way we support our partners and the standards we hold ourselves to every day.

Why Workforce Assured accreditation matters now

The timing matters.

HMRC’s guidance on the new rules for umbrella company supply chains makes it clear that from 6 April 2026, responsibility for unpaid PAYE can move up the labour supply chain in certain circumstances. Where the correct PAYE is not paid, HMRC may pursue the agency with the direct contract to the end client, or the end client where no agency is involved.

HMRC also says employment businesses should carry out regular, reasonable and proportionate due diligence on umbrella companies, including identifying entities in the labour supply chain, understanding how workers are engaged and paid, and assessing risks of non-compliance.

That means compliance is no longer something businesses can afford to keep at arm’s length.

For agencies and end clients, choosing the right supply-chain partners now carries even greater weight. Confidence needs to be earned. Standards need to be evidenced. And due diligence needs to stand up to scrutiny.

That is where Workforce Assured accreditation has real value. It provides additional independent assurance that the systems and controls behind a business have been reviewed and assessed against a recognised standard.

What Workforce Assured accreditation means for agencies

For agencies, Workforce Assured accreditation offers an extra layer of reassurance in an environment where compliance expectations are rising fast.

Agencies need partners they can trust. Partners who understand the regulatory landscape, take governance seriously and operate with strong internal controls. They also need to be able to show clients that they are working with businesses that support transparency and reduce supply-chain risk.

Independent accreditation helps support that position. It gives agencies added confidence that the provider they are working with has been assessed against a compliance-focused standard and is committed to lawful, transparent workforce practices.

In practical terms, that can help strengthen due diligence, support procurement conversations and provide greater confidence when selecting umbrella and self-employed solutions.

What Workforce Assured accreditation means for end clients

For end clients, Workforce Assured accreditation is another marker of trust, accountability and reduced risk.

Labour supply chains can be complex, and complexity creates exposure. As regulation tightens, end clients are placing greater focus on who sits within their supply chain and whether those businesses are operating in a lawful, transparent and well-governed way. HMRC’s 2025 policy paper on umbrella company reform explicitly framed the changes as a response to non-compliance in labour supply chains and an effort to encourage stronger due diligence.

An accredited provider offers added reassurance that compliance is not being left to assumption.

It shows that systems, controls and processes have been independently reviewed, helping end clients feel more confident in the partners supporting their workforce.

What Workforce Assured accreditation means for The Sterling Group

For The Sterling Group, this is a proud achievement and an important milestone.

It reflects the work that has gone on behind the scenes, the strength of the processes we have built and the standards we have continued to invest in. Workforce Assured accreditation is not about collecting a badge for the sake of it. It is about demonstrating, independently, what has always mattered to us as a business: compliance, accountability and doing things properly.

It also strengthens our position as a trusted compliance partner for agencies and end clients across the supply chain.

We understand that trust is earned through consistency. Through transparency. Through strong governance and a genuine commitment to lawful workforce practices. This accreditation reinforces that commitment and gives our partners even greater confidence in the way we operate.

A milestone worth celebrating

We are proud to have achieved Workforce Assured accreditation, and proud of what it represents.

This is a milestone for Sterling Solutions Umbrella Limited, Sterling Solutions Rail Limited and Sterling CIS Limited, but it is also part of a much bigger picture. It reflects the standards we have been working towards, the compliance-first culture we have built, and the responsibility we know comes with supporting agencies, end clients and contractors in a changing regulatory environment.

As the market continues to evolve, our focus will remain the same: strong governance, robust systems and compliant workforce solutions that give our partners confidence.

Because for us, compliance is not just part of the job.

It is part of who we are.

Celebrating 27 years at the top

Valentine’s Day is usually reserved for flowers, chocolates, and grand gestures. But in the world of recruitment, payroll, and compliance, love looks a little different. It looks like doing things properly, every time. It looks like showing up, delivering on promises, and keeping standards high even when nobody is watching.

That is exactly what The Sterling Group has been doing for 27 years.

This Valentine’s, we are celebrating a legacy built on premium service, hard graft, and a commitment to being the best, not just on the good days, but for the entire 27-year run.

In 2026, we are proudly celebrating 27 years at the top.

A relationship built on trust

In business, trust is not a slogan. It is the outcome of thousands of decisions made consistently over time.

Sterling’s story is simple in the best way: do right by people, build processes that stand up to scrutiny, and never cut corners. That approach is why so many recruitment agencies, contractors, and partners have stuck with Sterling year after year.

Because when things matter, like pay, compliance, and reputation, you do not want “good enough”. You want rock solid.

27 years of doing the work

Longevity is not an accident. It is earned.

For 27 years, Sterling has kept raising the bar through changing regulations, evolving expectations, and a market that never stands still. While trends come and go, Sterling’s work ethic stays the same: stay sharp, stay accountable, and keep improving.

It is not about chasing shiny shortcuts. It is about consistency, resilience, and a team that takes pride in getting it right.

Premium service, with standards to match

“Premium” gets used a lot. Sterling backs it up.

Premium is not just the service you provide, it is how you provide it. It is the responsiveness when clients need answers quickly. It is the clarity when things get complex. It is the confidence partners feel when they know the job is being handled by people who know the industry inside out.

Sterling’s approach is built around dependable service and high-touch support, with a focus on making life easier for recruitment agencies and contractors. Not with grand promises, but with proven delivery.

FCSA approved, because credibility matters

Compliance is not a box to tick. It is a standard to uphold.

Sterling is FCSA approved, a marker of credibility and a clear signal that processes, systems, and outcomes are held to rigorous expectations. For partners and clients, it means reassurance. It means transparency. It means knowing you are working with a business that takes compliance seriously and does not treat it as an afterthought.

In an industry where trust can be hard won and easily lost, that matters.

VeriPAYE: a trusted partner of The Sterling Group

Sterling has never been interested in doing things “almost right”. That is why the partners Sterling chooses matter.

VeriPAYE is a trusted partner of The Sterling Group, strengthening the standards Sterling is known for and supporting what matters most: compliance, clarity, and confidence for everyone involved.

In a space where regulations shift and expectations keep rising, having the right partners in place is not a nice-to-have, it is essential. VeriPAYE brings added reassurance through a shared commitment to doing things properly, with robust processes and transparent checks that help recruitment businesses and contractors operate smoothly.

It is a partnership that reflects Sterling’s wider approach: surround the service with the right expertise, keep standards high, and make it easier for clients to do business with confidence.

Rated Excellent on Trustpilot, because people have spoken

You can say you’re committed to service, but feedback tells the real story.

Sterling is rated Excellent on Trustpilot, and that is not down to one big moment. It is down to hundreds of everyday interactions handled with care, speed, and professionalism. It is the cumulative effect of a team that values relationships, takes ownership, and understands that reputation is built one experience at a time.

Great service is not a campaign. It is a habit.

The Sterling difference

After 27 years, you start to see what truly sets a company apart. It is not just what they do, but how they think.

Sterling’s commitment to being the best comes down to a few simple principles:

Consistency over compromise
Doing it properly is non-negotiable, even when it would be easier not to.

People first, always
Contractors, clients, partners, internal teams, everyone is treated with respect, clarity, and genuine support.

A culture of accountability
If something needs fixing, it gets fixed. If something can be improved, it gets improved. That mindset is why Sterling stays ahead.

Pride in the details
When you work in payroll and compliance, details are not small. They are everything. Sterling understands that, and it shows.

A Valentine’s toast to a team that never drops the standard

Valentine’s Day is about appreciation. So here it is.

To the Sterling team: thank you for 27 years of commitment, graft, and showing what “best in class” looks like when it is lived, not just claimed. Thank you for protecting clients, supporting contractors, and helping partners operate with confidence.

To Sterling’s clients and partners: thank you for trusting Sterling year after year. The relationships built over time are the real legacy, and the reason Sterling keeps pushing forward.

Here’s to the next chapter

If 27 years has proved anything, it is that Sterling is not interested in standing still. The same commitment that built this legacy is what will shape the next era.

So yes, this Valentine’s Day, we are celebrating love. The practical kind. The earned kind. The kind that comes from showing up, doing the work, and staying the best.

Love Sterling like we love Sterling. After 27 years at the top, it is safe to say: this is a long-term relationship.
