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

To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 12 June 2025 to Question 57661 on Water Charges, what estimate he has made of the average household water bill in each year from 2025 to 2030.

The price controls set by Ofwat under Price Review 2024 came into effect on 1st April 2025. The average customer bill will increase by 36% over the next five years. These bill rises equate to around £3 additional per month on average, before inflation, over the next five years. This will pay to fix crumbling infrastructure, which will dramatically reduce sewage spills and lead to cleaner rivers, lakes and seas.

The Secretary of State has secured agreement with Ofwat that funding for vital infrastructure investment is ringfenced and can only be spent on upgrades benefiting customers and the environment. Ofwat will also ensure that when money for investment is not spent, companies refund customers, with money never allowed to be diverted for bonuses, dividends or salary increases.
