What to do if…
your employer says you must repay an overpayment immediately

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Do not make an immediate separate payment under pressure. Ask for the claim and calculation in writing, check it against your payslips and bank payments, and reply quickly with a realistic repayment proposal if the amount is correct.

Do not do these things

  • Do not send a bank transfer or cash payment just because someone says it is urgent.
  • Do not agree to a repayment amount if they have not shown how it was calculated.
  • Do not sign anything new under pressure, especially anything that allows open-ended deductions.
  • Do not ignore the message; it may leave your employer to proceed without your input.
  • Do not assume the figure they quote is what you personally received; check whether they mean gross pay before tax or the net amount that reached your bank.

What to do now

  1. Ask for the details in writing today. Request:

    • the pay periods affected
    • the reason for the overpayment
    • the calculation showing how they reached the figure
    • whether the figure is gross or net
    • whether they plan to recover it through payroll deductions or by asking for a separate repayment
    • the proposed recovery date
    • the named payroll or HR contact handling it

  2. Save the demand and your records. Keep emails, messages, screenshots, payslips, bank statements showing wage payments, and any letters about pay changes, hours, bonus, sick pay, parental leave pay, holiday pay, or final pay.

  3. Check whether the amount looks right. Compare the employer’s calculation with:

    • what your payslip says you were paid
    • what actually reached your bank
    • your usual pay for the same period
    • timesheets, rota records, holiday records, or bonus information if relevant

  4. Reply in writing before you pay anything separately. You can say: “I am not refusing to repay any correct overpayment, but I need the written breakdown first. Please confirm the gross and net figures and do not make any separate repayment request until the amount and repayment schedule have been agreed.”

  5. Offer a repayment plan you can actually afford. If the overpayment looks correct, propose a fixed amount each payday or each month. If a lump sum would cause hardship, say that plainly and ask them to confirm an affordable schedule in writing.

  6. Ask them to talk before making deductions. Employers can generally recover genuine wage overpayments, including by wage deductions, but they should tell you and talk to you about how the money will be paid back. Ask them to confirm the amount and timing before any deduction is made.

  7. Check your contract, staff handbook, and any overpayment policy. Look for wording about payroll errors, deductions, final pay, repayment plans, and notice. If you are in a union, send the payroll message and policy to your rep and ask for help with the reply.

  8. If the amount is wrong or the deduction would be unaffordable, escalate calmly. Ask payroll or HR for a meeting and put the specific problem in writing: the amount is disputed, the calculation is missing, or the proposed recovery would cause hardship. If that does not resolve it, use the workplace grievance process and contact Acas for independent guidance.

  9. If you have left the job, keep everything in writing. Ask for a written statement of what they say is owed, how it was calculated, and why they say you are responsible for it. Do not agree to an immediate transfer until you have checked the figures and made an affordable written proposal.

What can wait

  • You do not need to decide today whether you will pay everything in one go.
  • You do not need to accept fault to start resolving this.
  • You do not need to agree a repayment schedule until you have seen the written calculation.
  • You do not need to escalate beyond payroll or HR immediately if you can first get the facts and put your position in writing.

Important reassurance

Payroll errors happen, and a sudden demand for money can feel alarming. Asking for the calculation, checking what was actually paid, and offering affordable instalments is a steady way to respond without refusing to deal with it.

Scope note

These are first steps only, to slow things down, verify the amount, and reduce the risk of a rushed agreement. If the sum is large, the calculation is disputed, deductions have already started, or you are facing threats or retaliation, get specialist employment advice.

Important note

This guide is general information, not legal, financial, or professional advice. What is reasonable can depend on your contract, workplace policy, how the overpayment happened, whether you are still employed, and the exact deductions being made.
