NMW compliance is about to become a matter of statutory enforcement for umbrella companies. From April 2027, the Fair Work Agency will take on oversight of umbrella companies under the Employment Rights Act 2025, enforcing deductions, National Minimum Wage, holiday pay and payslip transparency. Umbrella firms and the agencies that use them have the period before then to get deduction models and per-assignment pay calculations in order.
What Will the Fair Work Agency Enforce?
The Fair Work Agency will bring umbrella company pay practices under direct statutory oversight for the first time. NMW compliance sits at the centre of that remit, alongside deductions, holiday pay and payslip transparency.
The areas most exposed are the ones where umbrella pay models have historically been least transparent:
- Whether every worker receives at least the National Minimum Wage once deductions are applied
- How deductions are described, justified and disclosed on the payslip
- Whether holiday pay is correctly calculated, accrued and, critically, actually paid
- Whether the worker can understand their pay from the payslip alone
This is enforcement with teeth, backed by a single body with the power to investigate and act. The informal latitude that some operators have relied on will not survive contact with it.
Why Does NMW Compliance Trip Up Umbrella Firms?
NMW breaches in the umbrella model rarely come from paying a low headline rate. They come from deductions that quietly erode pay below the minimum once applied.
The National Minimum Wage is assessed after certain deductions and payments are taken into account. Where charges, so-called salary sacrifice arrangements, or opaque “margin” deductions reduce a worker’s pay below the statutory floor for the hours worked, the firm is in breach — regardless of the rate quoted at onboarding.
From April 2026 the National Living Wage rose to £12.21 per hour for workers aged 21 and over. Every assignment must be checked against the correct rate for the worker’s age and the hours actually worked, not a notional figure. A deduction model that works at one rate can fail at another, which is why per-assignment verification matters rather than a single blanket calculation.
How Should Umbrella Firms Prepare Before April 2027?
Umbrella firms should audit their deductions models now, not in the quarter before enforcement begins. The time between today and April 2027 is preparation time, and it is finite.
Priorities:
- Audit every deduction. Identify each deduction applied to worker pay, confirm it is lawful and properly authorised, and remove anything that cannot be clearly justified.
- Verify NMW per assignment. Check pay against the correct statutory rate for each worker and each set of hours, after deductions, for every assignment rather than relying on the headline rate.
- Fix holiday pay. Confirm holiday pay is correctly calculated, visibly accrued and actually paid, not retained or rolled up in a way the worker cannot follow.
- Make payslips transparent. Ensure the worker can read the payslip and understand exactly what they have earned and what has been taken from it, and why.
Agencies carry a stake in this too. Joint and several liability rules from 6 April 2026 already place PAYE and NI accountability on recruitment agencies and end clients rather than the umbrella. A supplier with weak NMW compliance is a supplier whose problems can become yours.
What This Means for Agencies and Workers
Agencies should treat umbrella NMW compliance as part of ongoing due diligence, not a one-off onboarding tick. The Fair Work Agency’s arrival raises the cost of placing workers through a non-compliant provider, and that cost does not stay neatly with the umbrella.
For workers, the direction is firmly toward protection: clearer payslips, deductions that must be justified, and a statutory body willing to enforce the minimum. For compliant firms, none of this should be a shock. It formalises standards that FCSA Accreditation has required of Members for years.
Conclusion
The Fair Work Agency does not change what good practice looks like — it makes poor practice enforceable. FCSA’s position is that NMW compliance, transparent deductions and properly paid holiday pay are baseline obligations, and the firms that already meet them have little to fear from April 2027. Those that do not should use the time remaining.
