I think the OP means the system whereby instead of social services supplying care, they give the disabled person money and they employ their own carers. I have never done it myself but professionally I have known people do it (I was an NHS community Occupational Therapist) and be very happy with the setup.
When my Mum came out of hospital she received a letter from the council saying that they would pay for her care at home, how much it amounted to, I have no idea.
