If you get to your house and its uninhabitable there is a proceedure whereby the uni can give you accommodation.
You'll get more info about it soon i believe (cant guarantee - dont work in off campus accommodatino personally).
If you do find that you cant live in it, get hold of the union's Welfare Sabb straight away and they can get warwick to help you quickly.
I dont think the uni can help you in getting out of your contract, but they can put you up.
