This outfit appear to be a classic bunch of rogue traders. They take payment from members of the public upfront, then hold an online auction between energy assessors who live in the postcode area and then don't pay the assessor for doing the work!! I did 3 EPC's and haven't been paid for any of them despite several contacts via telephone originally and then via e-mail. They are no longer contactable via telephone! My advice is don't touch them with a bargepole!!!
