TDS still valid on contract extension? in Residential and Commercial lettings/Freehold issues Posted June 5, 2011 I can't find anything on TDS regarding this (and have never come across them before) so hopefully someone here with more experience knows the answer. Our rental contract was coming to an end and we found a new rental house to move to. Unfortunately, the new house fell through. An alternative rental house was found but we couldn't move in until a week after our previous rental contract would have expired (leaving us homeless for a week). So we asked our landlord if we could stay an extra week and pay him the same rental rate that we always had, for that extra week. He agreed. I didn't really think about the fact that there was no formal tenancy agreement/contract for that extra week. Or that we hadn't involved the lettings agency. The landlord managed the property and the rent always went straight to him. A lettings agency had set up the original contract a year before. We made all this agreement through email. We are now having a dispute with the landlord over the tenancy deposit (despite the property being in immaculate condition and professionally cleaned top to bottom when we left with receipts to prove it). We have tried to reach an agreement over the last three weeks but he is being totally unreasonable and uncontactable and I think arbitration is the only way to go now. The deposit was protected by the TDS. However, when I looked at raising a dispute, it said we could only do this if the deposit was protected when we vacated the property. If our formal tenancy agreement had run out, does that mean that our deposit was not protected when we left? Perhaps I'm being paranoid but does that stop us being able to open a dispute with the TDS?
