I am a previous tenant of D&H and had to pull teeth in order to get what was left of my deposit back. I had to raise a dispute of nearly 800 pounds which they charged us for various fees. Needless to say they lost and nearly 5 months later I got the money that was rightfully mine in the first place.
I would just like to warn tenants to read the contract carefully before you sign. There are much fairer agencies out there!! D&H charges completely unnecessary fees on the way in and out! I am extremely glad I took the time and effort to dispute their claim, but if you want to save yourself the time and effort and money - stay away!
