yeah, but it's a hell of a lot different to have to download each EPC individually compared to having a spreadsheet that can be sorted to just give you a list of all the properties that have recommendations to have the loft insulation level increased / windows replaced etc.An EPC data is readily available from the EPC Register. It doesn't contain any details of the homeowner only the address and rating of the building and the assessors details.
At the very least, I'd hope that they only made the data accessible to legit accredited companies, with RECC type safeguards in place so that there's at least something to try to stop abuse of this data.
