Managing a UK Contingent Workforce? What Every Global Employer Needs to Review in 2026

By Abby Robbins, Founder, Yellow Bricks Talent Search

If you’re a workforce planning leader sitting outside the UK  or inside a global HQ trying to make sense of what’s happening on the ground here  you will know that the UK employment market has had a busy few years. And 2026 is no different.

The Employment Rights Act 2025 received Royal Assent last December. It’s been described as the most significant overhaul of UK employment law in decades. The Act is being implemented in phases running from April 2026 through to January 2027. For global workforce leaders managing contingent populations in the UK, the implications are significant, particularly if you’re relying on zero-hours arrangements, agency workers, or a mix of contractor and employed models to flex your headcount.

At Yellow Bricks we support global employers with UK payroll, EOR, temporary staffing and Pilot-to-Perm™ solutions, so we’ve been helping clients prepare for these changes for months.

Here’s what I think you need to understand.

The Ground Is Shifting on Flexible Work

The UK has always been a relatively employer-friendly market when it comes to flexible resourcing. That’s still true  but the rules are tightening.

Proposed changes will limit zero-hours contracts and the use of agency workers, making it harder to engage them for urgent resourcing needs. Workers meeting certain regularity tests will now have the right to a guaranteed hours offer, reasonable notice of shifts and shift changes, and payment for shifts cancelled at short notice.

This matters if your UK contingent workforce relies heavily on on-call or variable-hours arrangements. The operational agility you’ve built your model around now needs to be supported by better scheduling discipline, clearer communication, and contracts that actually reflect how people are being engaged.

I’ve spent 20 years helping organisations build teams and manage workforce challenges, and I’ll be honest a lot of businesses I talk to are still running flexible workforce models built for 2015. The compliance expectation has moved, and many haven’t caught up.

Costs Are Rising. That’s Not the Whole Story.

From April 2026, minimum pay for workers aged 21 and rose to £12.71 per hour. Statutory sick pay increased to £123.25 per week and is payable from day one of absence with no waiting period and no earnings threshold. Day-one rights now also cover paternity leave and unpaid parental leave.

These changes increase the employment cost base for UK contingent workforce. For global employers used to modelling UK headcount costs from a central finance template, those templates need updating.

But here’s the nuance: rising costs aren’t necessarily a reason to avoid UK hiring. They’re a reason to hire more deliberately. The businesses I see getting this right aren’t cutting corners on compliance, they’re thinking harder about whether the people they’re bringing in are genuinely the right fit, before they commit to longer-term employment obligations.

That’s part of why we built Pilot to Perm™. The principle is simple: hire someone into a role through a structured interim or temp engagement, with a clear pathway to permanent employment once they’ve demonstrated they’re the right person in the right seat. It gives both sides the evidence they need before a long-term commitment is made. In a market where day-one rights now attach to a broader range of entitlements, that decision matters more than ever.

EOR Is No Longer a Workaround – It’s a Strategy

There’s a persistent misconception I come across when talking to global workforce teams: that Employer of Record is a stopgap. Something you reach for when you don’t have the bandwidth or the right contacts to organise it correctly.

That’s not what EOR is in 2026.

Compliance has moved to the centre of UK contingent workforce strategy.

What I see consistently is that global workforce teams are spending more time navigating employment regulation, worker classification and payroll compliance than they were five years ago. As hiring becomes more international, local expertise matters more, not less.

UK employment law is not generic. IR35 still applies and HMRC enforcement is intensifying, with investigations increasingly targeting multinationals with UK contractor populations. The Employment Rights Act adds new layers on top of that. The question isn’t whether you need local expertise  it’s whether you have it.

The Human Element Is Not a Nice-to-Have

I want to say something that doesn’t always make it into the compliance-focused conversations about EOR and contingent workforce management: the way people experience their employment relationship directly affects how well they work.

This sounds obvious. It’s also consistently underweighted in global programme design.

The best EOR and workforce partners now recognise that employee experience directly impacts retention, engagement, and productivity. That means localised benefits, self-service access to payslips and documentation in workers’ own language, dedicated support, and wellbeing provisions that reflect regional norms.

Global hiring is accelerating faster than engagement strategy. Distributed work requires deliberate design, employee engagement doesn’t scale automatically.

Yellow Bricks have been placing people in interim, temp, and professional services roles in the UK for a long time. The assignments that go wrong  and the people who leave early  almost never fail because of a skills mismatch. They fail because someone didn’t feel like they belonged, or because the onboarding was a postcode lottery, or because nobody checked in. That’s true of permanent hires. It’s doubly true of contingent workers who are already one step removed from the core business.

If your UK EOR or payroll partner can’t tell you how your UK contingent workforce population is feeling, you’re flying blind.

What Good UK Contingent Workforce Support Actually Looks Like

When global workforce leaders talk to me about what they need from a UK partner, the list usually includes:

Compliance-first structure. UK employment law expertise that goes beyond a platform and a template. Someone who knows what the Employment Rights Act means for your specific workforce model, and who is watching the rolling implementation schedule through to 2027.

Flexibility that holds up to scrutiny. Temp, interim, and professional services solutions that are built compliantly from the start not in retrospect. If your flexible model would fall apart under an HMRC audit, it’s not actually flexible, it’s just undocumented.

A pathway to permanence. Not every contingent hire should become permanent. But when the fit is there, having a structured, fair mechanism to make that transition one that works for the individual as well as the business is a meaningful competitive advantage. It’s also the right thing to do.

A person who picks up the phone. I know that sounds basic. In a market full of platforms, dashboards, and AI-generated compliance alerts, it turns out that a human being who understands your business and can give you a straight answer is harder to find than it should be.

The UK Is a Complex Market. That’s Also What Makes It Worth Getting Right.

The UK remains one of the most significant destinations for global contingent workforce deployment. After years of rapid growth in global EOR, the market is consolidating  larger providers are acquiring niche specialists to deepen their expertise in complex markets. The UK is one of those markets.

Getting your UK contingent workforce strategy right  compliant, human-centred, and structured for the employment landscape that exists now, not the one from five years ago  isn’t just a risk management exercise. It’s how you build a workforce that actually performs.

At Yellow Bricks, we’ve been doing this for 14 years. We offer EOR, payroll, temp staffing, professional services, and our own Pilot to Perm™ model for clients who want to hire with evidence, not hope.

If you’re working through any of this whether you’re setting up in the UK for the first time, reviewing a contingent model that’s creaking under new legislation, or trying to find a better way to convert the right temp to permanent  I would be glad to talk.

Frequently Asked Questions

What is an Employer of Record (EOR) in the UK?

An Employer of Record is a third-party organisation that becomes the legal employer of your UK-based workers on your behalf. The EOR handles payroll, tax, statutory benefits, and compliance with UK employment law  including PAYE, National Insurance, and holiday pay  while you retain day-to-day control of how and what the individual works on. It means you can hire in the UK without needing to set up your own legal entity here. At Yellow Bricks, we provide EOR services for global businesses who want compliant UK employment without the administrative overhead of establishing a subsidiary.

What is the difference between EOR and PEO in the UK?

The terms are often used interchangeably, but they describe different arrangements. An Employer of Record (EOR) becomes the sole legal employer of the worker  the employment contract is between the EOR and the individual, and the EOR carries full legal liability. A Professional Employer Organisation (PEO) operates on a co-employment model, which means your company remains the legal employer and shares responsibility with the PEO. Critically, a PEO requires you to already have your own registered legal entity in the UK. If you don’t have one, EOR is almost always the right route. If you do, a PEO can help you outsource the HR administration. Most global businesses hiring into the UK for the first time  or managing a contingent population without a permanent subsidiary  are better served by EOR.

What does the Employment Rights Act 2025 mean for contingent workers in the UK?

The Employment Rights Act 2025 received Royal Assent in December 2025 and is being phased in across 2026 and 2027. For contingent workforce programmes, the most significant changes include: statutory sick pay becoming a day-one right with no earnings threshold or waiting period; paternity leave and unpaid parental leave becoming day-one entitlements; tighter rules on zero-hours contracts, with workers gaining the right to guaranteed hours offers after meeting regularity thresholds; and an increase in the maximum protective award for collective redundancy from 90 to 180 days’ pay. The Fair Work Agency, established in April 2026, also brings stronger enforcement powers across minimum wage, holiday pay, and agency worker rights. If your contingent workforce model hasn’t been reviewed against these changes, it needs to be.

How do I hire temporary or interim staff compliantly in the UK?

Compliant temp and interim hiring in the UK depends on correctly classifying the worker, operating the right payroll structure, and ensuring contracts reflect the actual nature of the engagement. Agency workers engaged through a staffing firm like Yellow Bricks are employed by us and supplied to you — we handle payroll, PAYE, NICs, holiday pay, and compliance with the Agency Workers Regulations. IR35 rules apply where contractors are engaged through intermediaries, and HMRC enforcement is intensifying for businesses with UK contractor populations. The new umbrella company tax legislation introduced in April 2026 also creates joint and several liability in some supply chain arrangements, so the compliance structure you use matters more than ever. Getting this right from the outset is significantly easier than unpicking it later.

What is Pilot to Perm™ hiring?

Pilot to Perm™ is Yellow Bricks’ proprietary hiring model. Rather than committing to a permanent hire upfront, a candidate is brought into a role on a structured interim or temporary basis, with a clear and agreed pathway to permanent employment once both sides have had the opportunity to test the fit. It removes the guesswork from permanent hiring decisions, the individual has the chance to demonstrate their skills in the actual environment, and the business has the evidence it needs before making a long-term commitment. In a market where day-one rights now attach to a broader range of employment entitlements, making that permanent decision with evidence rather than instinct is not just commercially sensible, it’s the right way to treat people.

Do I need a UK legal entity to hire staff in the UK?

Not if you use an Employer of Record. An EOR uses its own UK legal entity to employ workers on your behalf, which means you can hire compliantly in the UK without setting up a subsidiary, registering for PAYE, or navigating UK employment law independently. It is typically faster, lower cost, and lower risk than entity setup — particularly for businesses testing the UK market or managing smaller headcounts. If you plan to scale significantly in the UK over the long term, you may eventually want your own entity, and an EOR can serve as the compliant bridge while you get there.

What should I look for in a UK EOR or payroll partner?

Beyond the basics of payroll accuracy and legal compliance, the things that tend to separate good UK EOR and payroll partners from poor ones are: genuine UK employment law expertise (not just a platform with a template), the ability to guide you through complex scenarios like redundancy, IR35, and the Employment Rights Act changes, a clear point of contact who understands your business, and visibility into how your contingent workforce is actually experiencing their employment. A partner who can only tell you what they processed last month, but not how your people are doing, is missing the point. Compliance and people experience are not separate concerns  they reinforce each other.
