This may be long - apologies
We rent out our house in the UK while we are living abroad.
New tenants moved in a year ago, found by a letting agency. The lettings agent was particularly poor and was fired between finding and installing our tenant so we had to fight to get a copy of the tenancy agreement etc. We gave them our DPS number and asked them to log the deposit there which they agreed to. I didn't check - I didn't know how inept they were at the time and was seriously ill so it wasn't a priority.
A year later and the tenants have just moved out. They were poor tenants for lots of reasons. Our house manager who did the exit Inventory told us that they have stuck sound proofing to the lounge walls (without our permission). The paint had come off in massive several metre wide patches and they have repainted the patches in different colours.
They have been asked to repaint those patches in the original colour, we have even given them the paint to do it with, then we will return the deposit.
We have spent £1000 already just sorting out the garden as they hadn't touched it for a year so we feel we are being very reasonable.
We have just discovered that the DPS never got their deposit so it has sat in our UK bank account for a year. The tenants have been told this and have now stopped all contact and are, I suspect contacting a solicitor to demand their deposit back without doing the work as we should have logged the deposit with the DPS.
I don't want to return the full deposit until they do the work to rectify the damage as it is a huge room that will cost several hundred pounds to rectify. I realise we are in the wrong for not logging the deposit, despite it being unintentional by us.
Do we have legal standing to keep part of the deposit if they don't repair the damage or should we just hand it all over before we get into trouble with the DPS?
Any advice gratefully recieved.
