Low Income Home Repair Help in England?

My sister Sheri lives in Nailsworth Glouster England. Sadly, my sis suffers very badly with huge mental health problems not helped by her lovely cottage falling into disrepair over the years. Currently my sis lives with no water, no heat, no kitchen, or bathroom, generally in the winter it is colder inside her home than outside.

I have very little money and the task is now to big, as it is almost a renovation project. Sadly my sis is very suicidal and self harms, she is very clever, but work never seems to work out, often not getting paid and hence has been left in financial ruin. Does anyone know of an agency that can help her with repairs?
