Do you have to repay a benefit overpayment? 

Not necessarily. If the Department for Work and Pensions (DWP) or your local council has asked you to repay thousands of pounds in overpaid benefits, the figure isn’t automatically correct or automatically recoverable. Here’s how to check, and what you can do if you think it’s wrong. 

Key takeaways 

• Not every overpayment demand from the DWP or your council is legally recoverable. 
• If the mistake was an official error, and you couldn’t reasonably have known you were being overpaid, recovery may not be allowed. 
• Overpayment figures are often miscalculated, particularly where earnings or deductions are involved. 
• You can challenge a decision through a Mandatory Reconsideration and, if needed, an appeal to the First-tier Tribunal. 
• Speaking to a solicitor can tell you where you stand before you agree to repay anything. 

The short answer 

If you’ve received a letter demanding repayment of overpaid Universal Credit, Housing Benefit, PIP, or another benefit, you don’t have to accept the figure at face value. Overpayment decisions may be wrong in law, wrong in calculation, or both.

Before you agree to anything, it’s worth having the decision checked. You may be able to argue that the overpayment isn’t recoverable at all, that the amount is incorrect, or that repayment should be reduced because of the hardship it would cause. 

What counts as a benefit overpayment?

An overpayment is where the DWP or your local authority says you received more benefit than you were entitled to. This most commonly comes up with: 

• Universal Credit (UC) 
• PIP, DLA, or Attendance Allowance 
• ESA or Incapacity Benefit 
• Carer’s Allowance 
• Housing Benefit or Council Tax Support 
• Historic Tax Credits (Tax Credits ended in April 2025, but HMRC and the DWP continue to recover past overpayments) 
• Pension Credit 

The DWP will usually issue a demand with little explanation of how the figure was reached. These demands can run into tens of thousands of pounds. 

Four reasons an overpayment might not be recoverable 

Official error

If the overpayment happened because the DWP or council made a mistake, and you couldn’t reasonably have known you were being overpaid, recovery may not be allowed. For example, you gave correct income details, but they weren’t processed. 

Misapplied law

Overpayments are sometimes calculated using the wrong rules. This turns up often in Housing Benefit cases, where councils misapply capital disregard rules or non-dependant deductions. 

Incorrect figures

The overpayment amount itself is often wrong. Earnings may have been averaged incorrectly, deductions misapplied, or dates assessed wrongly. 

Hardship and proportionality

Even where recovery is technically lawful, you may be able to argue that repayment in full would cause undue hardship, and that it should be reduced or waived.

“In my experience, overpayment figures are frequently wrong, wrong in law, wrong in calculation, or both. Before you agree to repay a penny, let someone who knows the regulations check the decision.” – Prakash Ruparelia, Consultant Solicitor at Setfords

 What you can do before you pay anything back 

• Ask for the decision in writing, including how the figure was calculated. You’re entitled to this. 
• Check the time limits. A Mandatory Reconsideration usually needs to be requested within a set window of the decision, so don’t sit on the letter. 
• Gather your evidence. Payslips, correspondence with the DWP or council, and anything showing you reported changes on time. 
• Don’t assume you have to agree a repayment plan straight away. You can request more time while the decision is being checked. 

Common mistakes to avoid 

• Paying without checking. Many people repay simply because a letter told them to. If in doubt, always have the decision reviewed first. 
• Missing the reconsideration deadline. Waiting too long can close off your right to challenge the decision. 
• Not requesting the calculation in writing. Without it, mistakes in the figure are hard to spot. 
• Assuming an overpayment is always your fault. Official error is a recognised and often successful ground for challenge. 

When to speak to a solicitor 

If you’ve received an overpayment demand and any of the following apply, it’s worth getting advice before you respond: 

• The figure seems too high, or you don’t understand how it was calculated. 
• You believe the overpayment happened because of an error by the DWP or council, not you. 
• You’ve been asked to repay tens of thousands of pounds. 
• Repayment would cause serious financial hardship. 
• Your Mandatory Reconsideration has already been refused and you’re considering an appeal. 

Prakash Ruparelia, expert welfare benefits solicitor at Setfords, can help by reviewing the decision and the evidence behind it, checking whether the figures are right, and preparing Mandatory Reconsiderations and appeals to the First-tier Tribunal (and, where there’s an error of law, the Upper Tribunal) where needed.
