Mandatory reconsideration: how to challenge a benefits decision
If you disagree with a decision about benefits such as Universal Credit or PIP, the first step is usually to ask the Department for Work and Pensions (DWP) to look at it again. This is called a mandatory reconsideration.
The time limit
You normally need to ask within one month of the date on your decision letter. Later requests may be accepted if you explain why you were late, but there are limits, so act promptly.
How to ask
Your decision letter explains how to ask — for many benefits you can phone, write, or use a form. For Universal Credit you can usually ask through your online journal. Keep a record of when and how you asked.
Making your case
- Say which decision you disagree with and why.
- Point to specific parts of the decision that are wrong.
- Include new evidence, such as medical letters or statements from people who support you.
- Ask for a copy of the evidence DWP used, if you do not have it.
What happens next
DWP sends a 'mandatory reconsideration notice' with the outcome. If you still disagree, you can appeal to an independent tribunal; the notice explains how. Free help is available from Citizens Advice and local welfare rights services.
