A PIP claim usually starts with a phone application, followed by the ‘How your disability affects you’ form and any supporting evidence. If more information is needed, an independent health professional may assess you by phone, video or in person, asking how your condition affects daily living and mobility. The Department for Work and Pensions then considers the evidence and sends a decision letter explaining whether an award has been made. If you disagree, you can usually request a mandatory reconsideration within one month; check the latest guidance on GOV.UK for the current process.
