The Liberal Democrats would change that. Zero carbon must be the default. Every new home should have solar panels and renewable energy as standard. Planning must include climate resilience and flood mitigation, as the hon. Member for Congleton (Mrs Russell) mentioned in reference to section 42 of the Flood and Water Management Act 2010. Retrofitting must be a priority.

I thank the hon. Member for his intervention, which gets to the heart of this debate. Whether it is building a damp-proof course correctly or installing cutting-edge climate technology, the Government have a responsibility to ensure that a strong regulator holds developers to account when they fail. As Members around the Chamber have said, we have seen failure, but that should not prevent us as Members of this House from setting a high bar for developers to reach.

The introduction of the new future homes standard represents a considerable improvement in energy efficiency and standards for new homes. From 2025, new homes will be future-proofed with low-carbon heating and high levels of energy efficiency. These homes will be zero-carbon ready, meaning that no further work will be needed to ensure that they have zero carbon emissions as the electricity grid continues to decarbonise.
