Conclusion
South East Water did not have the right processes in place to identify and mitigate risks at Pembury Works, despite previous warnings from the DWI. That the company had “normalised” critical risks and was “flying blind” in the lead up to the crisis is a fundamental failure for a water company responsible for a critical natural resource. In a perverse sense, Mr Hinton was right in saying that the events were “unforeseeable”; but only because the company had actively chosen to not put in the essential monitoring processes that would have enabled action before the outages began. As a result, the company failed to properly monitor threats such as ineffective coagulant dosing systems. A failure to have the right jar test processes meant that manageable problems escalated unnecessarily, undermining routine coagulant treatments, eventually and unnecessarily turning off the taps for businesses, essential services and tens of thousands of customers. (Conclusion, Paragraph 16) 39

As the Committee will be aware, on the 28 May, Moody’s published their decision to downgrade South East Water’s credit rating to Ba1 (outlook negative). This has resulted in a breach of Condition P26 of the company’s licence, triggering Ofwat’s duty to issue an enforcement order or agree suitable undertakings. South East Water is also subject to multiple ongoing enforcement proceedings via Ofwat and the Drinking Water Inspectorate (DWI). On 5 March 2026, Ofwat proposed a £22 million penalty for South East Water’s supply resilience failures following its investigation into major customer supply disruptions between 2020 and 2023. Ofwat’s consultation on this decision closed on 13 April 2026, and Ofwat are now considering the representations made. In April 2026, the Drinking Water Inspectorate concluded that the Tunbridge Wells incident in November/December 2025 was foreseeable and preventable, citing systemic operational failures, and placed the company into a formal Transformation Programme. Following the major outages in late 2025 and early 2026, in May, elevated temperatures drove increased demand, leading to significant disruption, with around 20,000 properties, mainly in Kent, experiencing intermittent supply. The disruption highlights my serious concern about the company’s resilience under predictable seasonal pressures. South East Water’s performance is clearly below the standard that customers and Government are entitled to expect. Repeated disruption to supply, weaknesses in operational resilience and the company’s ongoing regulatory breaches point to serious and unacceptable failings. The company is funded to deliver the necessary improvements, and it must now show credible leadership, a robust plan and early evidence of delivery. Government is working closely with Ofwat and the Environment Agency to ensure a strong, coordinated response that protects customers and restores confidence. Those affected must also be compensated promptly. Last year we doubled or more the compensation companies must pay to customers when they fail to meet standards, including incidents of supply outages or low pressure, and we also introduced new standards including for the issuing of ‘boil water’ or ‘do not drink’ notices. The incident in Tunbridge Wells was the first time a ‘boil water’ notice had been issued since the introduction of the new standard, meaning South East Water had to make mandatory payments to affected customers.
