  • Shareholders have agreed to provide a further £750 million of equity funding in AMP7, subject to satisfaction of certain conditions 1

Cathryn Ross and Alastair Cochran, Interim Co-CEOs of Thames Water said:
“It was an extremely challenging year for Thames Water and the water industry. Our network came under unprecedented pressure from record temperatures, a drought and a freeze / thaw event. At the same time, economic factors also impacted our financial results with high inflation driven by a surge in energy and chemical prices. In short, our performance was not as we – or our customers – wanted it to be.
“Despite this, we are in a robust financial position. We had £4.4bn liquidity as at 31 March 2023 and are extremely fortunate to have such supportive shareholders. Their commitment to delivering Thames’ turnaround and life’s essential service is reflected in the largest equity support package ever seen in the UK water sector, whilst taking no dividends out. 
“Given our performance, we launched a review of our turnaround two and a half months ago to identify what needs to change to deliver better performance, quicker. As a result, we are transitioning to a more focused Turnaround Plan – this targeted approach focuses expenditure on a smaller number of initiatives that will deliver substantial and sustainable improvements in key performance metrics over the next three years. 
“This plan builds on the foundations that have been put in place over the last two years and progress made this year. We have brought customer-facing teams back into our region and insourced the repair and maintenance of our water network. We’re fixing more leaks and customer complaints have continued to fall significantly. We have also increased investment in our networks and assets to record levels as we undertake a detailed review of our ageing Victorian asset infrastructure to determine what needs to be done to improve operational resilience and performance over the long-term.
“Our balance sheet remains robust and, while change will not happen overnight, we are confident we have the right strategy, team and support in place to deliver for our customers, communities and the environment in London and the Thames Valley.”
