My father is down to 24K in savings, what now?

He is in England.

He receives lifetime DLA middle rate daily, living, and higher rate mobility. He has pension credit and a couple of private pensions coming in.

The background is he inherited £100,000 from the sale of his mothers house about 10 years ago . He has been using that for his living expenses alongside his pension, DLA, and private pensions.

He pays for council care, which is about 2 1/2 thousand pounds a month. We have asked them to review it but they say he needs that level of care. (The carers don’t provide the time stated)

I know we have to apply for a reduction of his care once they savings hit below 26,000 . Is there anything I need to do benefit wise at this moment? Or is the threshold lower than 26 thousand?
