Yes, that's absolutely correct, it was the same with us. I'm not sure of the exact figures, but last year, as my husband needed to go into care, and he had less than about £14000 in savings, they took all of his State Pension, half of his private pension, and he lost his Attendance Allowance.
If the person going into care has between about £14000 and £24000 in savings, there's a sliding scale of how much extra you pay - over about £24000 means you are self funding. After John went into care, I changed my will, and left my half of the home, plus all my savings, to my children. That way, if I had predeceased John, the children would have had the value of half the home.
As there is nobody who wants to buy half a home, had I died first, the LA would have put a charge against the "half" that was still my husband's. I think it might be called a lien. Should your spouse go into care, and you are visited by someone from the finance department of the LA, you do not have to disclose any of your private information. Hope this helps.
