Ofwat launches investigation into South West Water leakage performance

Ofwat has launched an enforcement investigation into South West Water, relating to the accuracy of information reported by the company for its performance on leakage and per capita consumption (PCC).

Ofwat sets performance targets for companies on leakage and PCC. Companies are assessed against these targets annually and can be penalised or rewarded, depending on their performance.

In November 2022, Ofwat deferred a decision on the progress South West Water has made towards its leakage performance commitment, as it sought to understand how the company calculated its reported performance.

Ofwat will not provide further information on the investigation until it reaches a conclusion.

David Black, Ofwat CEO, said: “We are committed to holding companies to account for performance and for sharing timely, accurate, and complete data with us and their customers. We want to ensure that is the case here. A thorough investigation will now be carried out and we will provide updates in due course on our findings and whether there is any further action Ofwat needs to take.”
