The hon. Lady is making a characteristically good speech and raising many points on which I support her. She made a good point earlier on solid-wall insulation, and the price of oil in rural areas is at the moment beneficial in comparison to the past. With so many houses being heated like that, now, when the sun is shining—almost literally—is the time for this work to be done, as the oil price may go up again, in which case these houses will be in desperate times. We should act before the pain that could come later.
On the abandoning of the zero-carbon homes target, the hon. Lady will probably recall that that was a disappointment to many in the supply chain, who had geared up for zero-carbon homes only to be deflated on finding out that the Government had for some reason changed their policy.
