To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 21 May 2025 to Question 51132 on Water Charges, what assessment he has made of the potential impact of the rollout of (a) progressive water metering or rising block tariffs and (b) seasonal water metering in addition to the planned trials on its guidance entitled Charging guidance to Ofwat, published in January 2016.

The Government supports innovative approaches aiming to make bills more affordable for their customers.

Defra are not conducting separate assessments.

Ofwat regulates the trials by requiring companies to ensure all trials are consistent with good practice principles. Companies must also consult with the Consumer Council for Water to protect or exclude vulnerable customers, which ensures customers are protected while these important trials take place.
