I am sure that my hon. Friend will agree that we can tackle the issue of energy efficiency in new homes through building regulations, but it is important that we have a policy to deal with energy efficiency in existing houses. By including energy efficiency certificates as part of home information packs, are the Government not demonstrating that those certificates are a vehicle through which we can try to raise public awareness of existing energy-efficient homes across the board? If the Government, while pretending to be green, rejected a measure as modest as making energy certificates part of home information packs, that commitment to being green and to tackling climate change would be nothing more than skin deep.
