The question

To ask the Secretary of State for Environment, Food and Rural Affairs, how she plans to monitor compliance with proposed water efficiency standards.

Answered by Emma Hardy

We are consulting on tighter water efficiency standards for new homes in Building Regulations. Within this we have assessed the policy’s impact on home construction and will be considering developer responses to enable a smooth transition. Our assessment considered the policy at a national level and not specifically its impact on Buckinghamshire and Milton Keynes. Industry research found the cost of water efficiency is low for developers in comparison with the cost of development blockages caused by subsequent water scarcity. The cost of retrofitting water efficient devices is around £40-100 and can be offset by the incentives offered to developers by water companies.

The proposed measures will unlock stalled developments in areas of water scarcity and could unlock 1,000 homes for every 5,250 built, while saving households over £100 a year on bills.

The Government response to the consultation will outline how we propose to monitor and evaluate the final policy.
