After your PIP assessment, a health professional sends a report to the Department for Work and Pensions (DWP), but the DWP makes the final decision about eligibility and rates. You can ask for a copy of the report and check the decision letter, including the reasons and deadline. If you disagree, request a mandatory reconsideration, usually within one month of the decision date, explaining what is wrong and providing relevant evidence. If the decision stays the same, you can appeal to an independent tribunal using GOV.UK guidance, although the outcome depends on your individual circumstances.
