I got standard rate daily living PIP a couple of years ago and have been on it for some years before. However I can't find the letter and need it for proof for something. If I call the PIP helpline will it trigger a review? I really couldn't cope with that right now. There is also some Government service to request letters of benefits and pensions, I heard, but I don't know how to access that. If it is a simple sign in and download service I would prefer that. Many thanks.
