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

To ask the Secretary of State for Environment, Food and Rural Affairs, whether she plans to take steps to support (a) households, (b) businesses and (c) developers to increase the re-use of greywater.

A consultation launched on 23 September 2025 proposes tightening Building Regulations to see new homes fitted with Water Saving features, such as aerated taps and showerheads, and dual flush toilets. Strengthened Water Efficiency Standards through updated Building Regulations will boost housebuilding and keep more money in families’ pockets. Updated standards will bolster drought resilience and unblock developments in water scarce areas. Future innovations such as using recycled greywater in homes, is also being considered in a call for evidence running alongside the consultation.

The Independent Water Commission Report published in summer recommended that Government work with regulators to develop a new policy and regulatory framework to drive the adoption of reuse infrastructure in the household and non-household space. The Government will respond to the commission’s recommendations through a White Paper and new water reform Bill.

Government is also working with Ofwat to encourage higher levels of water and wastewater efficiency in new developments through environmental incentives.
