How The Fair Work Agency Has Changed What UK Compliance Looks Like

The Fair Work Agency went live on 7 April 2026. If you lead HR or People at a UK business, the question is no longer whether you're compliant. It's whether you can prove it, fast. That shift matters more than the legislation itself.

Most HR leaders already know the rules. They know the National Minimum Wage thresholds, the holiday pay calculations, and the Statutory Sick Pay obligations. What caught many off guard is that the FWA consolidates enforcement of all of these into a single body with the power to inspect without a complaint trigger, recover arrears going back six years, and levy penalties at 200% of underpayment. Compliance has always been a top priority, but now the pressure is on to be able to prove it, and quickly.

How the Fair Work Agency redefines compliance

The FWA changes what enforcement looks like. Previously, enforcement was largely reactive — a worker complained, a body investigated. Now, inspections are proactive. The FWA can walk in without a prior complaint, audit your payroll records, and hold you accountable for decisions made up to six years ago.

That's the evidentiary burden shift HR practitioners are talking about. Being compliant and being able to prove it on 24 hours' notice are completely different things. That gap is what HR leaders need to focus on now, to avoid future problems.

For businesses running payroll and HR data across spreadsheets, legacy systems, and disconnected platforms, a six-year audit trail isn't something you can assemble quickly. In many cases, it can't be assembled at all. That's a 200% penalty problem waiting to happen, not because the business was underpaying workers, but because it can't demonstrate that it wasn't.

Large employers with modern, integrated HR infrastructure may actually welcome the FWA, as it levels the playing field against competitors who've historically underreported or underpaid. For SME HR leads, the reality is more uncomfortable. Proactive inspection at this scale is a different operating environment entirely.

What six years of defensible records actually looks like

Six years is a long time, especially as it spans payroll system migrations, workforce restructures, contractor shifts, and changes in NMW rates. A defensible audit trail doesn't just mean payslips exist somewhere in the cloud. It means you can show:

• The correct NMW rate applied to each worker, at each point in time, including rate uplifts
• Holiday pay is calculated correctly for workers with variable hours or irregular schedules
• SSP records that reflect eligibility determinations and payment periods
• Agency worker records that meet equal treatment standards under the Agency Workers Regulations

Each of these requires structured, time-stamped, retrievable data — not a folder of PDFs and a spreadsheet someone built in 2021.

Ask your team this: if an FWA inspector asked for NMW compliance evidence for every worker from April 2020 onwards, how long would it take to produce it? If the answer is more than a few hours, you have a documentation problem — regardless of whether you have a compliance problem.

The three pressure points keeping HR leaders up at night

Holiday pay for variable-pay workers remains the highest-risk category. The rules aren't new, but the calculations are complex and historically inconsistent. Where commission, overtime, or irregular hours are involved, many businesses have never fully audited whether their methodology is correct — or applied consistently.

NMW for salaried workers sounds straightforward until you account for salary sacrifice arrangements, deductions, and unpaid working time. If workers are expected to complete tasks outside contracted hours and those hours aren't captured, the exposure is real.

Contractor and agency worker classification is where documentation is most often weakest. The FWA's scope extends to whether these workers are being treated in line with their legal entitlements. The onus is on you to show they are.

What a strong response looks like

HR leaders responding well to the FWA are doing three things.

First, they're auditing their evidence gaps before the FWA does. That means a structured review of the past six years of payroll data, focused on the four areas the FWA oversees: NMW, agency worker standards, holiday pay, and SSP. Then they’re looking for the gaps in the data rather than legal. Where is data missing, inconsistent, or not retrievable?

Second, they're consolidating HR and payroll onto systems that produce audit-ready records automatically. Manual records can't be defended at speed, and if your systems don't timestamp, version, and store worker pay data in a structured way, you're dependent on people — and people make errors, leave the business, and don't always follow processes consistently.

Third, they're briefing leadership on what the FWA means in financial terms. A 200% penalty on arrears is a material number. So is six years of back pay. This is a financial exposure that belongs in front of the CFO and the board, and not an HR risk to manage quietly.

Where Deel fits in

For businesses running global workforces — or UK teams alongside international contractors and employees — audit readiness is harder to achieve when HR and payroll data is spread across multiple systems and geographies.

Deel maintains structured payroll records across every country it operates in, including the UK, with time-stamped, retrievable data built for exactly this kind of scrutiny. Holiday pay calculations, NMW compliance tracking, and worker classification records are part of the platform, not managed manually on the side. That doesn't make compliance automatic, as the decisions still belong to you. But the evidence exists, and you can retrieve it fast.

If your UK HR and payroll infrastructure can't support a six-year audit on short notice, that's the problem to solve first.

If you’re looking to invest in an HR platform that centralises all of your people, payroll, and compliance records so you're never caught scrambling, Deel was built for exactly that. Whether you have people based solely in the UK or you’re running a globally distributed team, Deel removes compliance headaches and gives you the infrastructure you need to pull your people data fast.
