Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential merits of allowing listed building owners to install uPVC double glazing to improve energy efficiency.

Changes to improve the energy efficiency of a listed building need to be sensitive to the character, appearance and specific characteristics of the building depending on individual circumstances. Listed buildings are generally exempt from energy efficiency requirements where compliance would unacceptably alter the character or appearance of the existing building.

Further guidance on improving the energy efficiency of windows of listed buildings can be found on the Historic England website.
