No benifits for being type1. Only if there are compilations from it.
If you go down the route of private rent, which is high, would mean having to put down a high deposit and a months rent in advance. Only very occasionally you might get help with some housing benefit, but most private landlords won,t except housing benifits.
Other option is, to go onto the council house list. Each council is different as into how long you wait for a place and most councils now put you into a band ie a to H where a is usually for homeless people, but again that varies with each council. To give you an example, where I live, I was on the council list in band B, and I waited almost 11 years for a place.
The other option is, are there any family that can help out money wise to start you off to find a private let place
