Mental health & housing advise

Hi

i don’t know if this is the correct place, to share this but I’m looking for some advise I currently live in a flat and have been medically assessed and banded B priority homes are coming up on the bidding site but I’m no where near the top, I’ve been to my local MP and councillor but that doesn’t seem to do much, my 3yr old is autistic and our 4th floor balconey is a big safety issue he loves to climb and can walk along to neighbours balconeys and it’s just no safe. Is there anyone I can contact to help us get a move as I want to stay in the LA as we are in process of completing EHCP. 
once the weather get nicer I will struggle with my mental health as I have to restrain my son as he will try to get out on the balcony and will climb window ledges to get out there and my home becomes so hot in summer with my son very little sense of danger I become a prisoner in my home not being able to have balcony door and windows open so he can’t escape
