Dropping out of Uni - paying for accommodation Watch
if the uni successfully re-lets your room, that might minimise any fees (mine were just capped at 2000 swiss Francs, in a similar situation to yours - oh, and they arrived two months after having left, carefully & meeting every condition that was supposed to have been met, or so I thought)
So either you can put up a notice and ask if anyone wishes to take your room, phone 07-xxxxxx etc, sublet/find your new lessee for your uni
or ask the university themselves as they will surely have someone on a waiting list. Go and talk to Housing, try to avoid my large bill!
You may be able to get someone to take your room (check Facebook groups for your accommodation, etc). Stick it up on some housing sites where possible.
Worst case scenario is that you may just have to pay for your room. Maybe you could use it and get a job wherever you're living there? Earn the money back type thing.
Best of luck!
