Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether he has made an estimate of the amount of non-residential building roof space that is (a) available and (b) suitable for the installation of solar panels.

No such estimate has been made.

However, deploying rooftop solar remains a key part of the Government’s clean power mission, and it continues to be one of the most popular and easily deployed renewable energy sources. Solar is also an important part of the Government’s strategy for increasing energy performance of buildings, and the Future Standards this year will ensure our new buildings are fit for a Net Zero future. The Warm Homes plan will set out pathways for decarbonisation of all buildings, including non-domestic ones. Further details on the Warm Homes Plan will be set out soon.
