Just posted this on the other thread about insulation also (by misake). Sorry, but feel it is a bit important, so, doing it twice.
I think you will find that although there are a number of agencies that have employed people to do this nationwide, they should be wearing ID badges. An appointment would be made by telephone for someone to come and inspect your home, and that appointment would be or should be confirmed by the surveyor, prior to the visit. So don't allow the door knocking folk into your home. If you are interested, it would be better to contact the Council direct or British Gas.
