I had no problem getting my PIP 3 years ago. The local council here has a benefits advisor and he filled in the form for me asking me the relevant questions and advising me how to deal with the face to face assessment. That was no problem as a lovely lady visited me at home and went through the process with a great deal of understanding as she was a nurse of some years experience. In Scotland, these assessments are no longer carried out by ATOS or any other private company. The Scottish Government decided that they would deal with assessments directly and have employed their own staff to deal with claimants. This means that they are more sympathetic towards claimants as they are no longer chasing targets.
I also had a letter recently advising me that instead of the benefit running for 3 years as previously, it would continue for 10 years before I was reassessed. That was a great relief as I was in a bit of a panic about whether I would still qualify even though my condition is a lot worse now.
For many reasons, I am grateful to live in Scotland as the Government here have the health and well-being of the people as one of their priorities unlike the uncaring, money driven policies pursued by Westminster.
