Day Centre Contributions

I have just received a letter from my local council which states, as my son got an increase in his ESA in November last year of £16.40 a week his day centre contributions are going up from £11.55 a week to £28.39 a week from 06/04/2020, (not giving me much notice to sort this out).
Does this make sense to anyone?

They should do a proper financial assessment annually. Are you claiming any disability related expenditure to get this figure reduced?
