Thames Water, Yorkshire Water, and Northumbrian Water will face unprecedented fines totalling £168 million following a major investigation by the water regulator Ofwat. The fines—£104 million for Thames Water, £47 million for Yorkshire Water, and £17 million for Northumbrian Water—are the largest ever imposed by Ofwat. They result from a “catalogue of failure” related to illegal sewage discharges into rivers and the sea.
Investigation Findings And Regulatory Action
The probe found that all three companies routinely discharged sewage into water bodies, failing to restrict these discharges to exceptional circumstances as legally required. This continued violation has led to substantial environmental harm and affected customers. Ofwat’s probe was prompted by public outcry and evidence suggesting that illegal sewage dumping was significantly worse than initially believed.
According to the Environment Agency, sewage spills in England rose by 54 percent in 2023 compared to the previous year. The increase has led some residents to withhold their water bills in protest.
Government And Industry Reactions
Environment Secretary Steve Reed welcomed Ofwat’s action, describing it as essential for addressing the “unacceptable destruction” of waterways. Reed also announced plans for fundamental reforms in the water sector to reduce sewage pollution, protect consumers, and encourage investment in infrastructure upgrades.
Ofwat’s investigation found a direct correlation between high levels of illegal discharges and outdated or poorly maintained treatment works. Thames Water had operational issues at nearly 70 percent of its treatment plants, while Yorkshire Water had problems at 16 percent of its sites and faced breaches at 45 percent of its storm overflows.

Future Regulations And Company Responses
In response to the investigation, Ofwat has proposed raising water bills by an average of £94 over the next five years, a measure described as “a bitter pill” by Chancellor Rachel Reeves. This increase is part of a broader plan to reduce sewage spills by 44 percent by 2030 compared to 2021 levels. Critics argue that these measures are insufficient and unfairly burden consumers.
Thames Water reported increased pollution incidents, attributed to delays in investment for capacity upgrades.
Charles Watson, the chair and founder of the campaign group River Action, said:
“Last year sewage was discharged across England, Northern Ireland, Scotland and Wales more than 596,666 times. That’s over 1,600 times a day – and with many of these discharges being illegal, this situation is completely unacceptable.
“Thankfully the water regulator, for so long toothless, is finally waking up to the scale of the public’s outrage and we are starting to see some meaningful penalties being imposed upon the worst offenders.”
Thames Water said:
“We take this matter very seriously and have cooperated at every stage of Ofwat’s investigation. We regard all untreated discharges as unacceptable, even when they are permitted, and are taking action to improve the health of our rivers as a key area of focus and investment.”
Northumbrian Water has been contacted for a statement regarding the fine.
