TL;DR

The UK National Minimum Wage (NMW) and National Living Wage (NLW) are statutory pay floors set by the National Minimum Wage Act 1998 and updated annually. From April 2024, the NLW for workers aged 21 and over is £11.44 per hour. Staffing agencies operating as the employer of record for temporary workers bear primary liability for NMW/NLW compliance, including for any deductions or arrangements that bring effective pay below the legal minimum. HMRC enforcement can require back-payment for up to six years and carries naming and shaming provisions.

What This Means in Practice

The NMW/NLW is not just a pay floor - it is a compliance calculation that accounts for all working time and all deductions, not just the hourly rate on a payslip. A worker paid £12.00 per hour can still be below the NMW if deductions for equipment, uniform, or tools bring their effective hourly rate below £11.44. The legal calculation compares total remuneration (after all relevant deductions) to the total number of NMW-qualifying hours worked in the pay reference period.

The rates from April 2024 are: £11.44 per hour for workers aged 21 and over (the National Living Wage); £8.60 for workers aged 18-20; £6.40 for workers aged 16-17 and apprentices in their first year or under 19. These rates are reviewed annually by the Low Pay Commission and typically increase each April. The government's stated target is for the NLW to reach two-thirds of median earnings by 2024, meaning rates are expected to continue rising.

NMW-qualifying working time includes all time the worker is required to be at the employer's disposal, including waiting time between jobs for workers on standby or zero-hours contracts, time spent travelling between work sites where travel is required as part of the job, and training time required by the employer. Travel from home to a fixed place of work is not qualifying working time. However, travel between assignments on the same day, or travel to an assignment on a new site that the worker was not informed about in advance, typically qualifies.

Deductions that reduce NMW pay include: charges for accommodation (capped at £9.99 per day as of April 2024 under the accommodation offset), uniform costs deducted from wages, tool rental deducted from wages, and penalties or charges imposed by the employer as a disciplinary mechanism. Deductions made for the employer's own use or benefit are caught by the NMW calculation; deductions for the worker's own use (such as pension contributions or salary sacrifice for benefits) are treated differently. Salary sacrifice arrangements can create NMW compliance issues if the sacrificed amount brings hourly pay below the minimum - pension auto-enrolment contributions at minimum statutory levels do not typically breach the NMW, but higher voluntary contributions from salary sacrifice may.

Why Recruitment Agencies Need to Know This

Agencies are the primary employer of record for the temporary workers they supply, which means NMW liability sits with the agency in the first instance, even when the client controls the worker's working time. An agency that pays a worker £11.44 per hour but then deducts a compliance fee, an umbrella margin, or a tool rental charge that brings effective pay below the minimum faces HMRC enforcement regardless of what the client pays the agency in the bill rate.

HMRC's NMW enforcement team operates a named-employer scheme under which businesses found to have breached the NMW are publicly named and shamed on GOV.UK. The scheme operates separately from any financial penalty. Agencies named in past rounds have included some of the UK's largest volume recruiters - the scheme does not reserve itself for small operators. Named rounds are published annually and generate significant press coverage, making NMW compliance a reputational issue as well as a financial one.

The financial penalty for NMW underpayment is 200% of the underpayment (halved if paid within 14 days), subject to a maximum of £20,000 per worker. In practice, for large agencies running thousands of placements at marginal pay rates, aggregate penalties across a workforce can run to seven figures. HMRC arrears orders cover the full underpayment period up to six years.

For agencies operating umbrella payroll arrangements - where the umbrella company is technically the employer - the NMW calculation is applied at the umbrella level, not the agency level. But agencies that direct the umbrella on how to structure fees or deductions carry reputational and, in some structures, legal exposure if the umbrella's arrangement breaches the NMW.

In Practice

A logistics staffing agency supplies warehouse pickers on zero-hours contracts at £11.44 per hour. The agency deducts £0.50 per shift as a "safety equipment maintenance contribution" and requires workers to purchase their own hi-vis vest at £12.00 during the first week of employment, deducted from the first payslip.

The compliance team reviews the arrangement ahead of an HMRC audit. The £0.50 per shift deduction constitutes a deduction for the employer's benefit - it funds agency-owned PPE, not the worker's personal property. The hi-vis deduction on the first payslip, where the worker is paid for 37.5 hours at £11.44, amounts to £428.50 in earnings before the £12.00 deduction. Effective hourly rate: £11.12. Below the NMW.

The agency removes the equipment maintenance deduction and absorbs the hi-vis cost as a business expense. Retrospective payments are calculated for affected workers over the previous pay periods. HMRC is notified voluntarily, which reduces the penalty applicable. Total retrospective liability: £4,200 across 84 affected workers. The agency avoids naming. The compliance team updates the onboarding deductions policy and adds a monthly NMW calculation check to the payroll sign-off procedure.
