Thames Water has revised its downgraded some of its commitments to customers. The company has published a Service Commitment Plan update.

It says that, despite some areas of performance improvement (including complaints and internal sewer flooding), the company’s original turnaround plan has not delivered the necessary improvements as quickly as hoped.

The Guardian has picked up the plan, noting that Thames Water expects to leak more water than previously thought, after its ageing pipes were overwhelmed by a deluge of rainfall.

The paper says that Britain’s largest water company has told regulators it now expects to leak 585m litres a day this financial year, up from a previous forecast of 550m litres a day.
