Update : spoke to DWP today, I have to complete a manual ESA claim and they are sending me out the forms as, despite losing the appeal, they are still showing me as a live ESA claim.
I have downloaded some of the guides from here that are excellent for hints and tips so I will make sure I answer correctly !!
Was told though that I need a new Doctors certificate as despite the other one running till November they will not accept it as I lost my appeal.
