My brother claimed this for my mother, who had Alzheimer's and was still living alone at the time. We had power of attorney and he specifically told the council NOT to send the letter to my mother, but to him, since (as so often) she was not aware that there was anything wrong with her, and would be incandescent at any suggestion that she was 'mentally impaired'.
They ignored him, and she was! Luckily I was staying at the time, and was able to pacify her by saying it was the useless council, they must have muddled her up with someone else - I would sort it out.
