Christ so much info in this thread which isn't something to go along with and pretty useless and time wasting in some cases.
Essentially the onus is on THEM to prove you caused the damage. If there is no signed DETAILED inventory of condition with pictorial evidence from the start of the tennancy then you could in theory have turned it into a dump. As there is no baseline showing its condition before you moved in then there is NO WAY to prove is wasn't left in the state it was at the start. Thus all deposit should be returned and most of it will be if going through teh deposit scheme arbitration.
Questions (please answer these):
1.) Is there a DETAILED starting inventory and leaving inventory (describing condition not just listing assets) with pictures? Are they signed?
2.) As asked earlier, what is being taken off your deposit by the LL (landlord) / LA (Letting agent), and what did you apparently damage?
Next stages
- Check the links regarding deposit schemes. if you have no paperwork saying that you are with one of them then call then up and speak to them to find out if it is protected (only 3 of them so shouldn't take too long)
- You need to send a formal letter/e-mail requesting the return of the full deposit within 10 days.
- Gather all your evidence, photos, inventories (before/after), tennancy agreement (READ IT!!!!).
- If you don't receive your money back, or they only call rather than write (you NEED written evidence), or they just fob you off saying X,Y,Z damage neglect etc, DON't get worked up and emotional. Send another letter saying they have 10 further days to send the full deposit back, you have sought advice from the deposit company and will be raising a dispute if the monies isn't received.
- Can explain the rest when we get there

FYI, I have won back money from student LLs used for betterment (had them squirming and sending cheques through just before going through with small claims, plus after moving out of London this year I got every single penny back froma thieving one who also wanted betterment, through the mydeposits arbitration scheme.)
