South East Water's Communication Failures Exposed During Winter Outages

The Communication Crisis

South East Water failed to adequately communicate with customers during outages last winter that left tens of thousands of people without water, a report has concluded. Fewer than one in 10 SEW customers were satisfied with how the company handled the water supply crisis that stretched across parts of Kent and Sussex last winter, the consumer council for water said. The report found communication was the company's greatest failing.

Customer Impact and Dissatisfaction

Mike Keil, the chief executive of the consumer council for water said: "Our research lays bare the scale of disruption inflicted on the lives of tens of thousands of South East Water customers last winter. People understand that things can sometimes go wrong with their water and sewerage services, but they expect their water company to minimise the impact – not make it worse. With the right handling, companies can build trust during challenging incidents, but when the response falls short, it can make a bad situation even more difficult."

The Scale of Water Disruptions

The winter disruption to water supplies hit in November and December when around 24,000 customers lost water supply or pressure in the Tunbridge Wells area after a water quality failure at the Pembury Water Treatment Works. A formal precautionary boil water notice was issued from 3 December 2025 and lifted on 12 December 2025. Then weeks later in January this year some 69,000 properties were hit with water shortages and low pressure.

Customer Experiences During Outages

One customer surveyed for the report said: "You suddenly realise how much you rely on water for everything." Another customer shared: "If we had known it would be several days, I'd have planned things very differently... I was starting to think if it goes on much longer then I just have to move out because this is not an option for me to live here." A third customer noted: "I think the messaging from the very beginning was very confusing and then coupled with the constant 'it'll be back later today, back tomorrow morning, back tomorrow evening.' We weren't fed accurate information."

Vulnerable Customers Left Without Support

People with health vulnerabilities also highlighted concerns about the outage, especially in relation to maintaining hygiene. The report found that about half of customers in vulnerable circumstances who were registered for priority services said they did not receive the support they expected. This failure to protect the most vulnerable customers has become a significant point of criticism against the company.

Regulatory Consequences

The report was published as South East Water faced further criticism for water outages which saw hundreds of households across Kent and Sussex without water during the hottest days of the year last week. The company, which faces a £22m fine from the industry's regulator, Ofwat, over serious disruptions to the water supply over many years, had comprehensively failed to deliver for the consumers it served, according to MPs who accused senior executives of incompetence.

Future Outlook for South East Water

As the company continues to face mounting criticism and regulatory action, the future of South East Water's leadership and operations remains uncertain. With the CEO stepping down and significant financial penalties looming, the company will need to fundamentally reassess its customer communication strategies and infrastructure maintenance to restore public trust in its services.
