We will provide a detailed breakdown of any deductions from your deposit on a room-by-room basis so you can easily negotiate any discrepancies with your housemates. There will be separate sections for items such as keys, unpaid admin fees etc. Each room will also be itemised and there will be a cost per item listed. As the deposit is treated as a whole (due to a joint and severally liable tenancy agreement) this will help you to divide up who is responsible for each deduction, if at all.
