Complete guide to employer rights to recover overpayment. Learn about legal limits, the 10% rule, written consent requirements, Employment Rights Act s.13(1), and case law protections.
Employers have a legal right to recover overpayment (wages paid in error), but the right is limited. Under Employment Rights Act 1996 s.13(1), deductions must be: (1) authorised by contract in writing, (2) required by law, or (3) agreed in writing by you. The 10% rule: deductions cannot exceed 10% of gross weekly wages without written consent for each deduction. Sunderland Polytechnic v Evans (2007) limits claw-back to genuine mistakes (overpayment errors), not disputed payments. If employer took too much or without consent, you can claim repayment of the unlawful deduction at tribunal. Interest of 8% per annum applies.
Check if deduction meets three tests: (1) Is it in your contract in writing? (2) Is it required by law (tax, NI, court order)? (3) Did you agree to it in writing? If NO to all three, the deduction is unlawful. Even if yes to one, the 10% rule may apply. Gather your contract, payslips, and any written agreements about deductions.
Calculate 10% of your gross weekly wage. If employer deducted more than 10% in one week without your written consent for that specific deduction, the amount over 10% is unlawful. Example: gross weekly wage £500; deduction £60 (12%) exceeds 10% by £5. The £5 is unlawful unless you gave written consent. Collect evidence: payslips showing deductions, contract terms, any written agreements.
Send formal written request for repayment of unlawful deductions, calculated with 8% interest per annum from when deduction was taken. Give employer 14 days. If refused, file ET1 claim at Employment Tribunal (free) claiming unlawful wage deduction. Tribunal will order repayment plus interest and possibly costs if claim was frivolous to defend.
Your gross weekly wage is £400. Employer deducted £50 (12.5%) for an alleged overpayment without your written consent. The amount over 10% (£10) is unlawful. Claim £10 repayment plus 8% interest. The remaining £40 may be lawful if contractual and in writing.
You were paid £2,000 in salary on 1st and 15th of the month (paid twice in error). Employer deducted the duplicate £2,000 from next payslip without notice. This is a 10% rule violation unless your contract explicitly covers payroll errors. Claim the amount over 10% as unlawful deduction. If no contract clause, claim full amount.
Employer paid £3,000 bonus; later claimed it was not earned and deducted it. This is disputed payment, not genuine overpayment. You can claim it back - employer cannot unilaterally claw back disputed wages. File tribunal claim. Burden is on employer to prove bonus was not earned.
You were given final written warning for misconduct. Contract allows deduction for disciplinary purposes (exception to 10% rule). But deduction must still be reasonable and proportionate. If deduction wipes out your entire month's pay for a minor breach, tribunal may find it unfair under Sunderland Polytechnic v Evans.
Employer deducted £100 for uniform damage without any contract clause allowing it. This is unlawful - no written authorization. Even though it's under 10%, the deduction fails the first test (not in contract in writing). Claim full £100 repayment plus 8% interest.
Employer deducted notice pay owed (£800) from your final payslip as 'overpayment recovery'. Illegal. Notice pay and holiday pay cannot be clawed back as overpayment. These are wages you've earned. Claim full amount at tribunal. Termination overpayment claims are treated more strictly.
