My Lords, I declare my interests as set out in the register. If we are to improve the uptake of heat pumps, does the Minister agree that we need to improve the uptake of energy efficiency measures, so that the pumps are more effective in the homes they are installed in? At ping-pong on the then Social Housing (Regulation) Bill, his colleague the noble Baroness, Lady Scott of Bybrook, promised that the Government would issue a consultation on heat efficiency standards in the social housing sector within six months of Royal Assent. That six months has now run out, but the consultation has not even started. I wonder if he knows when it is going to start?
