You won't get a home assessment without your GP writing to the Assessment Provider explaining why you cannot attend at their offices, the letter must be unambiguous about your abilities so phrases such as might have problems or could lead to a deterioration in the claimants conditions will not be helpful.
If the letter is available before you return your PIP2 then include, but don't delay returning the form to wait for it.
