There are essentially three steps to the process:
Call the Department of Work and Pensions (DWP). You will be asked a number of questions in order to confirm your identity and to find out whether you satisfy the basic PIP qualifying conditions. Once this has been established they will send you a form entitled “How your disability affects you” (PIP2) for you to complete.
Accurately and truthfully complete the “How your disability affects you” (PIP2) form, sign the confirmation declaration, attach a copy of all supporting medical or other evidence, for example, GP letters, therapist reports, visual impairment certificates etc, and send all relevant documents directly to the DWP.
Be prepared to attend an Assessment Centre for a face-to-face consultation, normally conducted by the healthcare professional assigned to your case.
