Can my landlord demand extra money- in the UK?

yes he can sue if you refuse to pay the additional monies. he will have to show proof of the damage and cost to repair, in order to win. Do you have pictures of the condition of the place when you moved in and when you moved out, or any other proof you did not cause the damages he is claiming? In the USA, tenants do a final walk through with the landlord to make sure everyone agrees on the condition of the place and what the tenant may be responsible for repairing or paying for repairs. Some landlords still try to stick the tenant with extra charges etc but the burden of proof is on them.

UK: For a landlord to get all or any of the deposit the landlord has to prove you left damage as the landlord legally doesn't hold the deposit it legally has to be held in an insurance scheme and you legally need to be told which one.......... so if this is a slumlord who has illegally held the deposit they are not taking you to court as they face legal action for breaking the deposit laws. The tenant can ask to be shown receipts or estimates for items that have been deducted from the deposit.

The answer is yes a landlord can take you to court for costs of damage you left that is over and above your deposit and they have to prove in court the damage from photographs take prior to your living there and photographs after you left and quotes or invoiced from trade people to repair the damage

He can if he can prove there was damage caused after you left.

This is why my husband and I take pictures on the last day we leave anywhere to prove the condition we left it in. That way if anyone comes after us and says we left a huge hole in the wall and a big stain on the carpet we can say "Um, no, we most certainly did not", and pull up the pictures.

Generally within a month or two would be reasonable.

Ask him to provide a full breakdown of the damage costs so you can review

tell him to get lost

He does not have to wait at all.
