Question to the Department for Levelling Up, Housing & Communities:

To ask the Secretary of State for Levelling Up, Housing and Communities, whether his Department has made an assessment of the effectiveness of water efficiency technologies for developments with (a) water scarcity and (b) nutrient concerns.

The department does not assess individual technologies, but the Government recognises the role water efficiency technologies can play in our efforts to address water scarcity and in supporting the delivery of homes affected by nutrient neutrality.

As set out in the Secretary of State’s written Ministerial Statement of 19 December 2023 (HCWS161), the Government is committed to reviewing building regulations to allow local planning authorities to introduce tighter water efficiency standards in new homes.
