Asked to Provide a Fit Note having been on long term sick!

Long story, but ultimately I’ve been asked to provide a Fit Note AGAIN to kick start the assessment process for Universal Credit. I have Relapsing MS and was diagnosed 12 years ago. There has been several errors made by DWP in my case and this is a longstanding issue. I have to go pleading again to my GP and the Practice Manager for another fit note, just so I can gain back my Support Group status that I was getting when I was on ESA. I’ve lost out on thousands of pounds waiting for the DWP to sort it, yet I have to go crawling asking for another fit note.

Anyway, I was wondering if anyone ever considered obtaining a Private Fit Note to the DWP??.. My GP is going to go crazy when I ask her for another one. I’d rather just pay for it.
