Can a DWP Debt Be Written Off or Disputed?

Yes, DWP debts can be challenged or waived under certain conditions. Individuals facing financial hardship, long-term health issues, or experiencing errors in overpayment calculation may be eligible for partial or full debt write-offs. However, this requires communication with DWP and submission of supporting evidence.
When Can a DWP Debt Be Waived?
A DWP debt may be waived if repayment would cause severe financial hardship or if the overpayment resulted from official error. In cases where the person is terminally ill or unable to manage daily living due to health conditions, waivers are also considered.
The DWP evaluates waiver applications on a case-by-case basis. To be eligible, you must demonstrate that repayment would significantly affect your ability to cover essential costs like rent, food, and utilities.
It’s important to provide documentation, such as medical records or income statements, to support your claim during the waiver request process.
How to Appeal an Overpayment Decision?
If you believe the DWP’s decision is incorrect, you can appeal.
- Start with a mandatory reconsideration, this is the first step before a formal appeal.
- You must request this within one month of receiving the overpayment letter.
- Submit written reasons explaining why you think the decision is wrong.
- Include any new evidence, such as payslips or medical documents.
- If not satisfied with the reconsideration outcome, proceed to an independent tribunal.
Keep copies of all correspondence and maintain a record of phone calls and reference numbers. You can seek free assistance from debt help services to prepare your appeal.
What Does DWP Debt Management Actually Do?
