South East Water Fined £22.5M for Repeated Supply Failures

South East Water has been fined £22.5 million by the industry regulator, Ofwat, for repeated supply failures in Kent and Sussex between 2020 and 2023. The failures affected over 280,000 customers, with some experiencing repeated disruptions.

Investigation Findings

Ofwat’s investigation revealed that the water shortages were exacerbated by South East Water’s failures to develop and maintain an efficient water supply system, despite the root cause being extreme weather events The Guardian. The regulator found the company did not adequately plan for potential disruptions, learn from past incidents like the 2018 “Beast from the East” cold weather wave, or analyze the underlying causes of the problems BBC News.

Specifically, Ofwat highlighted failures to maintain key infrastructure, including service reservoirs, boreholes, and major pipes BBC News. The company’s response to supply problems between 2020 and 2023 was described as “unhurried and disorganised,” with shortages of bottled water and insufficient support for vulnerable customers BBC News.

Recent and Ongoing Investigations

The proposed fine covers issues from 2020 and 2023 and does not include more recent incidents. Ofwat is currently conducting a separate investigation into major supply interruptions between November 2025 and January 2026, which left up to 16,000 homes without water for almost a week in December and affected approximately 30,000 properties in January Sky News.

Environment Secretary Emma Reynolds has called for a review of South East Water’s operating license following the recent outages The Guardian.

Company Response

South East Water initially filed for a judicial review of Ofwat’s draft decision and sought an injunction, but the court rejected the injunction BBC News. The company stated it is now considering Ofwat’s draft decision and will respond through the appropriate channels Sky News.

Financial Impact

Ofwat’s interim chief executive, Chris Walters, confirmed the fine will be paid by the company and will not be reflected in customer bills The Guardian.

Broader Context

This penalty follows a similar case involving South West Water, which admitted to supplying water unfit for human consumption due to a parasite outbreak in Devon, sickening almost 150 people. Last year, Thames Water received a record £104 million fine for environmental breaches related to sewage spills Sky News.
