Water regulator Ofwat has announced plans to impose a £22 million fine on South East Water following supply failures that affected more than 286,000 customers between 2020 and 2023.

The regulator determined that the water company was unable to cope during periods of high demand, resulting in service disruptions across its coverage area. Ofwat stated that these failures caused significant stress for affected customers who experienced water supply interruptions.

The proposed penalty reflects the scale and duration of the supply problems, which persisted over a three-year period. The fine represents one of the regulatory actions taken by Ofwat to hold water companies accountable for service standards.

South East Water serves customers across parts of Kent, Surrey, East Sussex, West Sussex, Hampshire, and Berkshire. The company has faced scrutiny over its ability to maintain adequate water supplies during peak demand periods.

The £22 million fine is subject to consultation processes before being finalized. Ofwat's enforcement action underscores the regulator's commitment to ensuring water companies meet their obligations to provide reliable services to customers.
