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

To ask the Secretary of State for Housing, Communities and Local Government, with reference to the building regulations review, what assessment he has made of the potential effect of lowering the water requirement to 100 litres per day on water efficiency.

In 2019 DEFRA launched a consultation and call for evidence on measures to reduce personal water use. The consultation sought views on labelling water-using products, building regulations for water efficiency, metering and smart metering and behaviour change.

DEFRA will be publishing a response shortly which will lay out proposals including those relating to building regulations.
