No. You are free to come and go as you please.
You are required to pay a deposit as an integral part of the acceptance process to book your room in halls. The deposit is non-refundable, the payment is reserved and credited against your final instalment of residential fees (minus any deductions or charges). All or part of the deposit may be retained by QMUL as a contribution towards any loss or costs suffered by QMUL, as a result of a cancellation made outside of the licence cancellation period.
All loss/damage charges will be charged via your residential account and an invoice will be sent to inform you of this charge by email, where you will be required to pay this amount immediately. A list of standard charges can be found in the Residents' Handbook.
