£0 remaining for debt arrears

D has come far from his homelessness and drug habits, and has started to rebuild his life. He still has disabilities, and claims Personal Independence Payment and Universal Credit, but is no longer drug taking. D is in supportive living, but has had to pay for extra support which he was not told about and, due to very low income, this has caught up with him and is in arrears. He has not been eating properly and not taking hygienic care of himself, due to trying to clear the arrears.
