Hi EMK123
I would start at your local Citizens Advice Bureau, they are very good at finding charitable grants, or try your local Welfare Rights Organisation;
advicelocal.uk If you were ever in the armed services then the Royal British Legion may be able to help.
I sometimes use Turn2us for help with grants, their contact number is 0808 802 2000 or website
