To poppy, calcotti and everyone else who contributed advice to any queries I have posted here.
Today I (finally) received my letter from DWP. Rather than go to the tribunal, they have "reviewed" my application and have changed it from Daily Living enhanced, 4 points for mobility and a review early 25 to enhanced for both Daily Living & Mobility and they`ve also made it an ongoing claim.
I`m not a fan of champagne, but I might have to make an exception

Thank you everyone who contributed.
Andy
