Alexa You are completely wrong. The reason that recipients aren't told what the money is to be spent on is because people's conditions are so variable and often there is very little they can do to improve the situation.
If you are crippled with arthritis and in constant pain, there is very little a carer can do to help you, but if the AA can pay to replace the curtains your sheltered flat came with and you hate, with some that you like, it does a lot to make life better for you, because when you are racked with pain and trying to watch television, to not have curtains you hate in full sight does so much to lift your spirits and maintain your mental health. The same thing applies to the examples I gave above of a lonely old man living in one room with severe arthritis. He bought a tv with a remote control, fish and chips once a week and a neighbour put a bit of money on the horse for him each weekend, which meant he had three visitors during the week, all of whom would spend time talking and chatting to him and it broke up his solitude.
No one knows what the home conditions are of people on AA, what help they need that will make life better, so if having a gardner in, or a cleaner or whatever helps then that is what the money should be spent on - and by not tying strings to AA, that is exactly what the government intended.
