Water: Prices
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 10 July 2025 to Question 64768 on Water: Prices, what estimate Ofwat has made of the average increase in water bills for homes with gardens affected by seasonal water metering.
Answered by Emma Hardy
Ofwat has not conducted a specific bill impact assessment for homes with gardens for companies trialling this method of charging.
South West Water estimated that 55% of household customers would save on its seasonal saver tariff and 95% of customers would save on its summer peak tariff; South West Water has designed the trial to be revenue neutral within the trial groups. Anglian Water has estimated that 2 out of every 3 customers would be no worse off or marginally better off under its seasonal tariffs, compared with its standard charge.
