Responding to Benefit Overpayment Letters

An overpayment letter from the DWP will typically state:

• The benefit involved (Universal Credit, PIP, Housing Benefit, etc.)
• The period of the overpayment (the dates during which you were overpaid)
• The total amount of the overpayment
• The reason for the overpayment (change in circumstances, official error, suspected fraud, etc.)
• How the DWP proposes to recover the overpayment

Read the letter carefully and check the figures against your own records. Look at whether the period stated is correct, whether the reason matches your actual circumstances, and whether the amount appears to match what you were paid during that period. Errors in overpayment calculations are not uncommon.

If you believe the overpayment is wrong — either in the amount, the period, the reason, or because you believe you did report the relevant change — you can request a Mandatory Reconsideration. You have one month from the date of the decision letter to do so.

In your MR request, explain specifically what you believe is wrong. For example: "I reported a change in earnings on [date] via my UC journal, reference [X]. The overpayment should therefore only cover the period before that date." Attach evidence of any reports you made — UC journal screenshots, recorded delivery receipts, or confirmation emails.

If the MR does not resolve the dispute, you can appeal to the Social Security Tribunal. For Housing Benefit overpayments administered by your council, contact the council's benefits team first and then escalate to the Valuation Tribunal if necessary.

If the overpayment is confirmed and you need to repay it, you have options:

• Deductions from ongoing benefits: The most common method — the DWP deducts a fixed amount from your monthly Universal Credit. The standard rate is 15% of your standard allowance, rising to 25% for fraud-related overpayments.
• Request a lower deduction rate: If deductions cause financial hardship, contact the DWP and request a reduced rate. You will need to explain your financial situation. Reductions to as low as 5% are possible in genuine hardship cases.
• Lump sum payment: If you have savings or receive a windfall, you can pay off the overpayment in full. Contact the DWP for payment details.

If you receive a court summons for a benefit debt, seek urgent advice from Citizens Advice or a debt adviser. Court judgments carry additional costs and can affect your credit file.

Not all overpayments are your fault, and not all are legally recoverable. There are two important challenges you can make beyond a simple Mandatory Reconsideration about the amount.

Official error overpayments: If the overpayment was caused entirely by a DWP or HMRC official error — and you could not reasonably have known you were being overpaid — Housing Benefit overpayments caused by local authority error are not recoverable under the relevant regulations. For Universal Credit, official error does not automatically prevent recovery, but it strengthens a waiver application.

Applying for a waiver: Even if the overpayment is confirmed as recoverable, you can ask the DWP to write it off (waive recovery) if repaying it would cause severe hardship and it would be inequitable to require repayment. Waiver applications are considered on the specific facts of your case and are not granted routinely — but where there is genuine financial hardship, a serious health condition, or evidence of official error, they are worth pursuing. Submit a written waiver request explaining your circumstances with supporting evidence such as a budget sheet and medical evidence if applicable.

Challenging recoverability: If you received a Tax Credit overpayment, HMRC can only recover it in certain circumstances — for example, if you failed to report a change, provided incorrect information, or did not respond to annual renewal notices. If HMRC caused or contributed to the overpayment, you can dispute whether recovery is appropriate under the Tax Credits (Definition and Calculation of Income) Regulations 2002. Contact a tax credit specialist or Citizens Advice before agreeing to repay a disputed Tax Credit overpayment.
