Thanks.I’m not aware of any unpaid for help. It might be worth approaching AgeUK , Dementia UK or Carers Org in your area as they may have information. Very much a long shot but if you or your loved one are/were in a trade 7nion they sometimes have help. Real long shot ask Social Services or GP.
It’s another area where there seems to be little help or at least little advertised. Good luck
