The LA are obliged legally to find him somewhere within the (invented) budget and if they can't tell you which homes these are then do like I did refuse to look at them as it's a waste of time (as I found out). Eventually they gave me some names that were within budget and my wife moved in about 6 weeks ago, it's not perfect but the staff are fantastic and essentially that's all that matters.
I think I looked at 9 places and everyone needed a top up, the highest was nearly £400 a week, the lowest about £150 so I told the social worker to up the budget or tell me the homes that fit, reluctantly she did and so far it's all working out quite well.
Along with my wife there are 3 other people there from the same assessment unit so I've known some of the other visitors for 6 months or more, we've compared notes as some of their partners/parents had been in care before and we're all pretty happy.
Getting them to pay more that they want to isn't easy if it can be done at all (I don't know anyone who has but they must be out there) I just stopped answering the social worker's calls until she stopped wasting my time and the time of all the homes I visited that were out of budget.
It's not that I wouldn't pay a top up, I could, but they don't seem to want to tell you what's in budget so presumably they don't want to overload anywhere with basic rate payers presumably so there's still rooms for the full paying self funders to subsidise them, cynical, who knows?
If, like me you're in the Greater Manchester West NHS region then I believe there are only 2 choices without a top up.
