Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what steps she is taking to encourage developers establishing new buildings to have (a) solar panels, (b) batteries and (c) heat pumps fitted; and what support is available to those developers.

The Government is committed to ensuring that the 1.5 million homes we will build over the course of this parliament will be high quality, well designed and sustainable. Renewable and low carbon technologies, such as solar panels, batteries and heat pumps, are a key part of our strategy to get to net zero via a decarbonised electricity grid. We must therefore take the opportunity, where appropriate, to encourage their adoption in new buildings.

In 2021 the Government introduce an uplift in energy efficiency standards. New buildings are now required to produce significantly less CO2 emissions compared to those built to previous standards. Already we have seen many homes being built with solar panels and heat pumps.

Future standards, to be introduced later this year, will set new buildings on a path that moves away from relying on volatile fossil fuels, ensuring they are fit for a net zero future. These buildings will be future proofed with low carbon heating and high levels of energy efficiency. No further energy efficiency retrofit work will be necessary to enable them to become zero-carbon over time as the electricity grid continues to decarbonise.

A consultation setting out proposals for what the new standards should entail was published in December 2023 and closed in March 2024. We are carefully considering the feedback received and will publish the Government response, setting our more detail on the content of the standards, in due course.
