Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, whether he plans to consult on Part G of the building regulations to improve water efficiency standards.

The Government is committed to enabling homes to be water efficient as part of the statutory Water Demand Target under the Environment Act 2021, to reduce the use of public water supply by 20% by 2037/38. The target is underpinned by a commitment to lower water usage in homes, to achieve a usage of at least 122 litres per person per day by 2038, on a trajectory to 110 litres per person per day by 2050.

Defra is working closely with the Ministry for Housing, Communities and Local Government to explore whether the Building Regulations 2010 could be amended to tighten water efficiency standards, enable consumers to use less water and save on their water and energy bills. Policy options on amendments to the Building Regulations have been collated into a draft consultation, and we are now working through steps to proceed to consultation.
