Excuse my ignorance of such issues, but is the principle of disability benefits to make up, at least in part, for extra costs incurred from having a chronic condition and/or disability where one has to pay for help?
After GTS suggested as we are over 70 we may be entitled, I went through the claim form as if I were my OH, with a long standing heart condition. If either of us get to a point where we can do very little for ourselves, then I'll have a look again. At present, he couldn't claim, in truth, to need help with anything on the form. It made me realise how incapacitated someone must be to qualify!
We have a nephew with early onset, fairly severe Parkinsons. I'd like to think that someone in his situation, with a family to support, gets the long term financial help he needs. His condition won't improve. He gets the top level everything, but it in no way compensates for his salary.
