The right hon. Lady speaks powerfully for her constituency, which I know has a specific issue. We mentioned housing developers, and one housing developer has put its head above the parapet to support the Bill. I am grateful for the support of Thakeham, and it is to be applauded for supporting the measure. Developers should support the Bill for sound business reasons. There is a clear market preference for homes with solar panels, and a relatively small proportion of the price will be rewarded with a decent payback, and customers want them. Politically, there is demonstrable cross-party support. In the last Parliament, 79% of Members were found to be supportive, and I suspect the percentage is higher in this new Parliament. The climate barometer tracks support for mandatory solar panels on new builds and found a clear majority of support among all parties’ voters, so doing this would place us at the centre of political gravity. Some 80% of Conservative voters, 89% of Labour voters, 92% of Liberal Democrat voters and 63% of Reform supporters responded to the survey in favour of mandatory solar panels for new build homes. Those same constituents rightly look to us to make the right and logical decisions on these matters. They back the measure because all the evidence points to clear benefits at every level, including the Government’s positive agenda on energy and climate. MCS Foundation research has found that mandatory solar panels on 1.5 million homes would be the equivalent of two additional Sizewell C nuclear power stations, which should give us all pause for thought. For a country that struggles to build infrastructure, we must not look past these easier, small-scale wins.
