@mikehughescq is totally correct Community Care Grants no longer exist in England, how confusing that the online guide published by the Job Centre doesn't make this clear.
For conformation of this fact see: https://www.turn2us.org.uk/jargon-buster/Social-Fund. Or for a more detailed look at the Local Welfare Assistance scheme that replaced it see: https://www.turn2us.org.uk/Benefit-guides/Emergency-Assistance/Local-Welfare-Assistance
Community Care Grants are still available for those living in Scotland https://www.citizensadvice.org.uk/scotland/benefits/help-if-on-a-low-income/scottish-welfare-fund-s/scottish-welfare-fund-community-care-grants-s/
Assuming you are in England, a Disabled Facilities Grant may well be the way forward, depending on your circumstances and the nature of the home adaptations you are assessed as needing. Definitely, the first step I would recommend you taking is requesting a home assessment by the Community Occupational Therapist.
