And make sure the deposit actually does go into a deposit scheme - there's a world of difference between being told it goes in, & it actually going in. You should be advised in writing where it is within 14 days of it going in.
You may also need to consider whether a new inventory check is needed. Presumably one was done when your tenancy started & the landlord may be happy to accept that & just deal with any deduction from deposit for repairs etc. when you eventually leave. If you don't have a copy of the inventory check docs. make sure you get them now.
