Hi Mark
Welcome.
This is not my forte I am afraid. I come into the category of being a doctor but, unfortnately, this avenue is outwith my field.
However, here is a website which may be of use.
http://www.gpss.tripoduk.com/nhscare/I did not see the programme so cannot comment. So far as I am aware ( and someone will correct me if I am wrong and if I am then apologies for misleading) but in Scotland I did not think we paid social charges.
From experience, my uncle has alzheimers and I know that my aunt pays a subsidised rate to his care home and the local authority pick up the rest. There is also "free care" for the elderly and infirm but, again, it depends on your circumstances whether this applies. In my aunts case she would be worse off going down this road as the local authority would then not pay a brass farthing.
Sorry I cannot be more specific but as I say it is outwith my field. You could try contacting this website and see if they could put you in touch with Pamela or perhaps they could even give you advice.
Keep us posted and let us know how you get on. I should not say this but although a doctor I am first of all one of the many disabled and like to see the "fat cats" getting their noses put out of joint. Please dont anyone tell my boss that!
Regards.
