Hi, I am an accredited Energy Assessor who belongs to the Institute of Domestic Energy Assessors. Anyone contemplating using Express EPC would be well advised to check our forums on this company, especially the threads that enlighten you about the owner and his list of ccj's. It would appear that although people are paying to commission an EPC, previously carried out work is not being paid to the Energy Assessor doing the work, word has got round amongst our industry and not many aware DEA's will do the work. Please be aware that it would appear that Express EPC do not directly employ any DEA's. They take your money (Strangely enough always about £39.95 irrelevant of size of house) and then hold a dutch auction amongst registered DEA's. Work going to the lowest bidder, who does the work and then receives no payment. If you require a reputable DEA may I suggest you visit our website at whatstheidea dot org dot uk and click on the find an idea member link. We have members across the UK who will carry out an EPC at below Estate Agents fee's and usually within 48 hours of commission.
