I have just experienced the same thing as Rena (please find it on the other reviews) had. I wish I had a chance to read this review before I have allowed them to do the so called "FREE assessment". Now I am facing a bailiff's unpleasant visit and a debt of over 2000. I contacted Hampton Lovett right after receiving the letter from DCBL which asked me to paid for the Administrative Fee for Non-Domestic Rates Review in March, but with no response from HL.
Today, the bailiff paid us a visit before we came to work. A letter sticked on the door to tell us to call them to discuss the matter, but giving no reason. I spent 10 minutes to find out what it is about. I then went on line to check the reviews on Hampton Lovett, and now I cannot tell how much I regret that I didn't do any research on this con company before I signed the FREE assessment paperwork.
I just want to tell anyone who is lucky enough to see this message: Please say no to them, avoid them and don't sign any paperwork, or otherwise you will be deeply regret!
