Been diagnosed a couple of years, with fairly moderate symptoms.
I decided to apply for pip last Dec, quite a lengthy process of mainly waiting rather than doing - I completed a form in Dec and had an assessment recently. I was awarded standard rate on both criteria, which equates to around £330 per month, a useful sum which is fixed for five years and not means tested.
So I still get it paid if I return to work.
I found it all quite painless and would encourage pwp who live in the UK to claim this useful support.
