Well just had my phone assessment. Took about 50 minutes with a lady called Alice. She was nice and polite and went through a load of questions with me.
I did get the impression that she knew more about my condition than I did because she asked me if the hospital had mentioned anything about an eruption (cant remember the full medical term she used) in relation to my heart. Obviously the NHS tell the DWP more than they tell you lol. I had presumed they had probably requested my medical notes though

She told me at the end that its just a case of waiting now and to contact the DWP in 8 weeks time if I haven't heard anything by then.
Overall it was a fairly painless process regardless of the outcome.
