To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential merits of the reuse and retrofitting of existing buildings as a lower carbon alternative to demolition and new build construction.

The Department recognises that the reuse and retrofitting of existing buildings can offer significant carbon benefits compared to demolition and new build, by avoiding emissions associated with new materials and construction. Improving the efficiency of existing homes and buildings, currently responsible for around one-fifth of UK emissions, is key to reducing energy demand, cutting Bills and supporting energy security.

Through the Warm Homes Plan the Government is prioritising upgrades to existing buildings including insulation, solar panels, batteries and low-carbon heating, alongside reforms to standards and advice to support high quality retrofit. New development will continue to play a role, and the Government has recently published the Future Homes Standard to ensure that new homes and non-domestic buildings are built with low carbon heating and high levels of energy efficiency.
