Don’t give up hope
when I first applied for PIP and the assessor cane to my house , she was very nice and as part of the assessment asked how far I could walk ( on a good day ) I think I was pretty doped up to be honest , but I kind remember her saying 30 something , can’t remember if it was 30 feet or metres ( big difference I know ) but in the heat of the moment and being doped up I think I just said yeah that one!
anyways fast forward to the decision letter , enhanced for daily living and standard for mobility
I realised a mistake had been made , probably genuine on both parts , I didn’t have any extra medical evidence to send for the MR but I wrote a heartfelt genuine letter and explained the misunderstanding between the 30ft and 30m
not long after I recieved a reply saying they had accepted this and award enhanced rate mobility
pip award was for 3 years and that was about 6/7 years ago in my early 30s
now I’m on an ongoing award for both components
so don’t give up hope and maybe do what I did and send a genuine letter explaining what you disagree with on your decision letter and explain in the most basic terms what you can and more importantly cannot do! Along with any extra medical evidence you have too
it’s a horrible time, but wishing you the very best of luck ??
