Moved into a new rented house last month. Just discovered that the agent has put only £950 in a deposit protection scheme, whereas I paid £1600 deposit (via bank transfer, so I can prove it, also the higher amount is on the tenancy agreement). The agent is nice and I'm sure this is just an oversight, but I can't work out whether it's in my interests to point out the mistake. Not protecting the deposit obviously means she is not entitled to hold any back at the end of the let, plus I could sue if I wanted. I should say that I've never had anything deducted from a deposit as I'm a very good tenant, nor do I plan on suing her, but since my last landlord turned out to be a total arsehole I'm aware if the possible benefit of keeping some powers in case I need them later! What would you do?
