Can an agent keep my holding deposit because my references failed, or because the move-in kept getting delayed?Beta*

Only in limited cases, and they must explain why in writing. If a landlord or agent decides to keep a holding deposit, they must tell you in writing within 7 days of deciding, giving the reason. If they don't, they lose the right to keep it, even if they would otherwise have had a good reason. A failed reference only justifies keeping it if you gave false or misleading information. Being turned down for a reason you had no control over doesn't. If the delay was on the landlord's or agent's side and the deadline for agreeing the tenancy (normally 15 days) passed because of them, the whole deposit must come back within 7 days.
