Energy-efficient Housebuilding

What steps he is taking to promote energy-efficient house building.

I thank my hon. Friend for his question, not least because as a proud member of the Chartered Institute of Building I take a keen interest in all things related to energy-efficient house building, so I am personally delighted that from 2025 the future homes standard will ensure that new homes produce at least 75% less carbon dioxide emissions than those built to current standards. These homes will be future-proofed, with low-carbon heating, high levels of energy efficiency, and no further refit work needed to enable them to become zero-carbon over time, alongside the electric energy grid.

British architects such as Bill Dunster are building not only energy-efficient homes but zero bills homes, which are brilliant for the planet as well as helping us relieve poverty. Will the Government commit that we will aim for the very highest standards, not least so that we do not have to retrofit later?

We are indeed aiming for the very highest standards; I do not think anybody could accuse us of being anything other than very ambitious. While some of the sector is already leading the way by building highly efficient, low-carbon buildings, it is important that all parts of the industry are ready to build homes that are fit for a zero-carbon future. The timeline we have set out delivers on our net zero commitments while providing industry with the time it needs to develop the supply chains and skills that will be necessary. I am hoping that I will get to join my right hon. Friend the Minister for Housing on his visit to the ZEDfactory in due course.
