For too long, investment has not kept pace with the challenges of an ageing infrastructure system, a rapidly growing population and climate change. Bills will therefore now need to rise to invest in our crumbling infrastructure and deliver cleaner waterways.

Ofwat published their final determinations for Price Review 2024 on 19 December. This will deliver substantial, lasting, improvements for customers and the environment through a £104bn upgrade for the water sector.

These bill rises equate to around £3 additional per month on average. This will pay to fix crumbling infrastructure, which will dramatically reduce sewage spills and lead to cleaner rivers, lakes and seas.

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.

All water companies offer affordability support for customers struggling to pay their bills and companies have more than doubled the number of customers that will receive help through social tariffs, from 4% to 9%, between 2025-30. The Government is working with industry to keep current support schemes under review to ensure that vulnerable customers across the country are supported.
