How long should adult disability payment review take?

Hi,

I was moved from PIP to ADP. I am on enhanced rate mobility and care. I was due a review in October of last year, I got the forms in September. On the advice of my Welfare rights worker, I ticked the box to say "No change". I am still getting full payment without any problems. The only issues I have is my bus pass is also due to expire and I need a letter to say that I am in receipt of ADP and when it is due to run out. I called SSS and they said, they have received it but no one has picked up my form yet and I am not priority as I am being paid full amount. I also wanted to use the mobility component to get a car on Motability as my mobility is deteriorating but I can't unless I have a letter detailing I have at least a year's award.
Anyone any idea how long this should take?

Just as an update because it might be helpful to others.
I heard from Social Security Scotland today. I have been re-awarded high rate for both care and mobilty for five years. This is following a simple "no change" application.
It is such a relief as we have never used the mobilty component for a car, preferring to use buses, taxis or hiring cars when necessary but my ability to use public transport is greatly diminished and not likely to get better. We are sussing out a car next week

Hi , I’m in the same situation regarding bus pass , expires March . Also send ADP form September, no reply. I will ask Money matters who helped complete my form about this. Fingers crossed 🤞🏼
