Steve Robertson, Chief Executive Officer, Thames Water said: “Our fundamental purpose is to serve our customers and I am pleased that we’ve made progress in 2017 that will benefit them now and over future generations. We’re committed to keeping customer bills as low as possible, so we will be returning £40 million of performance-related penalties to customers two years earlier than we needed to, keeping the expected 2018/19 bill increases below inflation.

"We’ve been investing heavily for more than a decade and we will continue to do so – we spent another £533 million on our infrastructure in the six months to 30 September. In areas where we’re not delivering we’ve committed to spending significantly more than planned to put things right, such as an extra £97 million on our largest ‘trunk’ water mains. Actions such as these will help us to get our leakage target back on track by 2020.

"Both our new and existing shareholders fully support the refreshed management team, and are aligned with our vision. They will not be paid a dividend this financial year, while we all focus on making the right long-term investment decisions for our customers.”
