Uniforms, tools and till shortages : calculate what you are owed

• ERA rules: a wage deduction is only lawful if statute requires it, your contract authorises it (and you were told), or you agreed in writing beforehand (GOV.UK / Acas).
• Retail till or stock shortfalls: while you stay employed, deductions are generally capped at 10% of gross pay per pay period; the full balance can come from final pay when you leave.
• Uniforms and tools required for the job usually reduce pay for NMW purposes if you bear the cost and are not reimbursed, whether you pay the employer or a shop (GOV.UK calculating guidance).
• Some contractual "fault" deductions (for example a till shortfall your contract says you are liable for) may not reduce NMW pay, but they still need a lawful ERA basis and the retail 10% limit may still apply.
• Accommodation has a special offset (£11.10 a day / £77.70 a week from April 2026). Charging above the offset can cut NMW pay.
• Keep payslips and receipts. Raise the issue with the employer, then Acas. Tribunal clocks for most pay claims remain 3 months minus 1 day now; from 1 October 2026 most become 6 months minus 1 day if the clock starts on or after that date.

1. Was the deduction lawful under the ERA?

GOV.UK (deductions from your pay) and Acas (deductions from pay and wages) summarise Part II of the Employment Rights Act 1996. In plain terms, an employer can deduct only if:

• the law requires it (tax, National Insurance, student loan via PAYE, court orders)
• your contract specifically allows that deduction and you were notified
• you agreed in writing before the deduction
• other listed situations apply (for example recovering an accidental overpayment, or unpaid strike time)

A verbal "everyone pays for shirts here" is not enough. If the deduction fails this test, you may have an unauthorised deduction from wages claim even before NMW maths starts.

2. Does it still leave National Minimum Wage intact?

Separately, GOV.UK's calculating the minimum wage guidance explains which deductions and worker payments reduce pay that counts for NMW. A deduction can be contractually mentioned and still create an underpayment if it knocks the average hourly rate below £12.71 (or the correct younger / apprentice band).

GOV.UK also lists limited situations where a deduction may take pay below NMW (tax and NI; certain contractual liabilities for something you have done; loan or advance repayment; accidental overpayment recovery; shares; accommodation within the offset rules; some voluntary third-party payments that are not a job requirement). Uniform and tool costs required for the job are not a free pass under that list.

GOV.UK is blunt: if the employer requires specific workwear and does not supply it free (or reimburse you), deductions or unreimbursed purchases always reduce minimum wage pay. That covers:

• branded shirts, aprons, or logo kit bought from the employer
• the same items bought from a third party because the employer insisted
• reasonable laundry or wear-and-tear charges when the employer provides a uniform

It does not matter whether the requirement sits in a contract or is "just how the shop runs". Generic "black trousers and a plain black top from any high-street shop" can still be an employment-related expense if it is a requirement of the job; GOV.UK notes employers may set a reasonable reimbursable limit when costs vary.

Exception flavour (misconduct / loss): if you negligently damage, lose, or fail to return a provided uniform, a reasonable contractual charge may not reduce NMW pay. That is a narrow path. Ordinary replacement of a worn shirt is different.

GBP example (uniform vs £12.71): You are 28, work 35 hours in a week, paid £12.71 an hour.

• Gross wages before the kit charge: 35 × £12.71 = £444.85
• Employer deducts £40 for two mandatory branded tops
• Pay left for NMW maths: £444.85 − £40 = £404.85
• Hourly rate for NMW: £404.85 ÷ 35 = £11.57

That is below £12.71. The headline rate looked compliant; the kit charge broke the floor.

GOV.UK treats tools, equipment and many job-related expenses the same way: if you spend money connected with the employment and are not repaid within a reasonable time, that amount reduces NMW pay. Personal Protective Equipment the employer must provide under health and safety rules cannot be shifted onto you without reducing NMW pay either.

GBP example (tools): Same 35-hour week at £12.71 (£444.85). You buy a required toolkit for £95 from a DIY store and are not reimbursed.

• Pay for NMW: £444.85 − £95 = £349.85
• Hourly: £349.85 ÷ 35 = £10.00

One purchase in one pay reference period can create a large underpayment for that period, even if later weeks look clean.

Cash and stock shortfalls are common in shops, cafés and restaurants. Two constraints often apply together.

ERA / contract first. GOV.UK says a till shortfall deduction is only in play if the contract (or prior written agreement) makes you liable. Acas repeats that till or stock deductions need a contractual basis.

Retail limit. While you remain employed, the employer generally cannot take more than 10% of your gross pay in any pay period for shortfalls. GOV.UK's example: £50 shortfall, £250 weekly gross → only £25 that week, with the rest from a later payslip. When you leave, they may take the full remaining amount from final pay. Acas adds that the employer should tell you in writing what is owed and reclaim within 12 months of finding the shortage.

NMW interaction. GOV.UK and Acas both list contractual liability for something you have done (till shortfall is the classic example) among deductions that may take pay below NMW. That does not erase the 10% retail cap or the need for a clear contractual right. It means a lawful shortfall clawback can sit below the NMW floor without automatically being an NMW breach, while an unlawful or oversized deduction can still be challenged as unauthorised wages deduction (and uniform-style costs still hit NMW).

GBP example (retail 10%): Weekly gross £444.85. Alleged till shortfall £80.

• Maximum that pay period: 10% × £444.85 = £44.49
• Residual £35.51 must wait for a later period (or final pay if you leave)
• Taking the full £80 in one week while you stay employed breaches the retail cap on GOV.UK / Acas framing

Living accommodation is the main benefit in kind that can count toward NMW, but only up to the official accommodation offset. From April 2026, GOV.UK rates are £11.10 a day and £77.70 a week. If the employer charges more than the offset, the excess reduces pay that counts for NMW. Free accommodation can add the offset to pay for the calculation. Food, cars and most other benefits do not count toward NMW.

1. Compare the payslip line with your contract and any signed agreements.
2. Keep receipts for uniforms, tools and laundry you paid yourself.
3. Run the GOV.UK minimum wage calculator for the affected pay reference period.
4. Raise the issue in writing with the employer; Acas encourages an informal fix first, then a grievance if needed (a grievance does not pause tribunal time limits).
5. For a clear NMW underpayment you generally choose HMRC enforcement or an employment tribunal path for that same underpayment (see Acas / GOV.UK enforcement guidance), not both.
6. For unauthorised deduction claims, notify Acas for Early Conciliation in time. Most pay claims: 3 months minus 1 day from the deduction (or most recent in a linked series). From 1 October 2026, most claims become 6 months minus 1 day if the time limit starts on or after that date (Acas time limits).

Northern Ireland uses industrial tribunals; this article follows the Great Britain framing.

• "You signed the handbook, so anything goes." ERA still needs a relevant authorising term or prior written agreement for the specific deduction type.
• "It's only £25 for a shirt." Small kit charges still reduce NMW pay when the job requires them and you are not reimbursed.
• "Till shortfalls have no limit." Retail workers have the 10% of gross per-period cap while employed.
• "We agreed verbally at induction." Get the authorisation in writing; GOV.UK and Acas stress prior written agreement or a clear contract term.
• "Final pay can swallow everything including unlawful kit charges." Leaving may lift the retail 10% timing rule for shortfalls; it does not legalise every deduction or ignore NMW.
• "Salary sacrifice childcare / cycle schemes are free." Genuine salary sacrifice reduces contractual pay and can drop you under NMW if the employer does not cap it (Acas / GOV.UK).

List every deduction and unreimbursed work cost beside hours and the £12.71 floor (or your age band). Paye Mes Heures helps you organise that trail in pounds before you email payroll or open Acas Early Conciliation. It is a preparation aid, not a ruling. Cross-check GOV.UK and Acas, then decide whether the fight is ERA deduction, NMW, or both.
