What law protects workers against unlawful wage deductions in the UK?
Part II of the Employment Rights Act 1996 (ERA 1996) prohibits employers from making deductions from a worker's wages unless the deduction is required or authorised by a statutory provision (such as income tax), authorised by a written term of the worker's contract of which the worker has been given written notice before the deduction, or consented to in writing by the worker before the deduction is made. The protection applies to workers, not just employees, covering casual workers and those on zero-hours contracts.
What counts as an unlawful deduction from wages?
Common examples of unlawful deductions include: failing to pay the agreed wage in full; deducting money for breakages, till shortages, or customer complaints without contractual authority; deducting training costs on termination without prior written agreement; failing to pay accrued but untaken holiday pay on leaving; underpaying the National Minimum Wage; and making deductions not authorised by the contract. Non-payment of wages entirely is also classed as an unlawful deduction.
Are holiday pay shortfalls covered by unlawful deductions law?
Yes. Workers are entitled to 5.6 weeks of paid annual leave under the Working Time Regulations 1998. Holiday pay must reflect normal remuneration including regular overtime, commission, and allowances — not just basic pay. A consistent pattern of underpaying holiday pay can be claimed as a series of unlawful deductions going back as far as the 2-year backstop under the Deduction from Wages (Limitation) Regulations 2014 allows. Non-payment of holiday pay on termination is a straightforward unlawful deduction.
How does HMRC enforce National Minimum Wage underpayment?
Workers who are paid less than the National Minimum Wage (currently £12.21 per hour for workers aged 21 and over from April 2025) can complain to HMRC's National Minimum Wage enforcement team. HMRC investigates complaints confidentially, can require employers to repay arrears going back up to six years, and can issue financial penalties of up to 200% of the underpayment capped at £20,000 per worker. Workers can also bring their own ET1 claim for unlawful deduction of wages independently.
Must I contact ACAS before bringing a wages claim at the Employment Tribunal?
Yes. Before submitting an ET1 claim form you must notify ACAS to start Early Conciliation. ACAS will contact both sides and attempt to reach a settlement without the need for a Tribunal hearing. The Early Conciliation period lasts up to six weeks and pauses your time limit. If conciliation fails you will receive an ACAS Early Conciliation certificate with a unique reference number, which you must include on your ET1 form.
What is the time limit for bringing an unlawful deduction of wages claim?
You must contact ACAS within three months less one day of the deduction (or the last in a series of deductions). This is a strict limitation period. Missing the deadline means your claim will almost certainly be rejected unless you can show that it was not reasonably practicable to present the claim in time and that you acted as soon as reasonably practicable after that. The Deduction from Wages (Limitation) Regulations 2014 cap backdated claims at two years.
How do I complete and submit the ET1 claim form?
Once you have your ACAS Early Conciliation certificate number, complete the ET1 form online at employment.tribunals.gov.uk. The form asks for your personal details, your employer's details, the ACAS reference number, and a description of your complaint and the amount claimed. There are no fees for Employment Tribunal claims. Once submitted you will receive an acknowledgement and your claim will be allocated to a region for case management.
What remedies can the Employment Tribunal award for unlawful wage deductions?
The Employment Tribunal can order the employer to pay the amount of any unlawful deduction plus interest. There is no cap on the amount of a wages claim, though the two-year backstop limits how far back a claim can reach. The Tribunal cannot award additional compensation for injury to feelings or aggravated damages in a pure wages claim, but if the deduction is connected to a protected characteristic such as sex or race you can also bring a discrimination claim alongside it.
What is tip theft and what does the Employment (Allocation of Tips) Act 2023 do?
Tip theft occurs where an employer retains or redirects customer tips that workers expect to receive. The Employment (Allocation of Tips) Act 2023, which came into force on 1 October 2024, requires all employers to pass on 100% of tips, gratuities, and service charges to workers without any deduction. Employers must have a written tips policy and maintain records of tip allocation for three years. Workers can bring a claim at the Employment Tribunal for failure to comply within 12 months of the breach.
