UK water company with 3 million customers slapped with £44.7m payout
The provider supplies water and sewerage to more than three million customers in over 1.4 million homes and business across Wales.
A major UK water and sewarage provider with millions of customers will pay out £44.7million after failures in its sewage network and oversight led to a series of spills and must now focus on “putting things right”, regulator Ofwat has announced. Welsh Water, a not-for-profit company which supplies more than three million customers in over 1.4 million homes and business across Wales, acknowledged that its service had “fallen short of the standards that our customers and regulators rightly expect” and said it was investing to improve spills, leaks and water quality.
Ofwat said it had accepted the Welsh Water's redress package, which was first proposed in March, following consultation. The water regulator said the supplier failed to properly operate, maintain and upgrade its wastewater network to ensure it could cope with levels of sewage and wastewater, and did not have adequate processes in place or oversight by senior bosses.
The enforcement package will include £40.6 million to reduce spills at specific overflows and reduce the environmental damage caused, tackle groundwater entering the sewer network, as well as an extra £4.1million to improve river quality in “extremely sensitive catchments”.

Ofwat said the package was more than the £40 million that would otherwise have been imposed as a fine and stressed it would be funded by the company, without adding to customer bills.
Ofwat's senior director for enforcement, Lynn Parker, said: “Our investigation found serious and unacceptable breaches in how Dwr Cymru Welsh Water has operated its wastewater assets which has resulted in excessive spills to the environment.
“With this investigation now concluded, we expect the company to focus on putting things right so that customers can regain trust in their water company.”
A Welsh Water spokesperson said: “The investigation considered both historic and more recent compliance, and we recognise that improvements are needed.
“Over the past year, we have already begun a major transformation programme across the business, including our wastewater services, focused on improving governance, strengthening operational oversight, accelerating investment and delivering better outcomes for customers and the environment.
“While we know there is much more to do and that it will take time to get to the level of performance our customers and regulators rightly expect, we are beginning to see early signs of progress in some key areas of performance.
“During 2025/26, leakage has started to reduce following increased repair activity and progressive metering, customer complaints relating to water quality have reduced following targeted work on our network, and incidents of internal sewer flooding have reduced.”
