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

To ask the Secretary of State for Housing, Communities and Local Government, what assessment his Department has made of the potential energy-efficiency benefits derived from using natural stone in public and private construction.

Energy efficiency requirements for new dwellings and buildings are set through the Building Regulations, which specify overall performance standards rather than mandating particular materials. This allows designers and developers to select the most practical and cost-effective materials for each project, including the use of natural stone where appropriate.
