Shareholders have approved Thames Water's plan for an additional £2 billion of expenditure aimed at improving performance and outcomes for customers, leakage and river health.

The Board and shareholders of Thames Water have approved a £11.5 billion business plan for the current regulatory period ending 31 March 2025, developed by Thames Water’s Executive team to improve performance and outcomes for customers, leakage and river health and to accelerate delivery of Thames Water’s turnaround. The revised business plan represents a £2 billion increase in expenditure, compared to the £9.6 billion agreed in the water company’s final determination for 1 April 2020 to 31 March 2025.

The UK's largest provider of essential water and wastewater services, serving almost 25% of the UK's population, Thames Water launched its turnaround plan in March 2021. That plan is designed to significantly improve Thames Water’s operational performance, deliver on its regulatory obligations, increase resilience and deliver better outcomes for its customers, communities and the environment.

An initial £500 million of new equity will be subscribed by shareholders this financial year. The Executive team is working with shareholders on plans to provide a further £1.0 billion of equity funding, which will be subject to certain conditions, to drive Thames Water’s turnaround over the remainder of the current regulatory period, and establish a solid foundation for Thames Water’s long term growth.


The Executive team will continue to reflect the ongoing turnaround in its next business plan to be prepared for the five-year regulatory period starting in 2025. A focus of that business plan will be to maximise the likelihood that Thames Water receives a regulatory determination that supports the turnaround. Thames Water shareholders acknowledge that further shareholder support may be required to improve financial resilience.

Sarah Bentley, Thames Water’s Chief Executive said: "Since joining in September 2020 I have engaged in understanding the challenges that led to Thames Water's long-term underperformance. In March last year, I launched our turnaround plan, to tackle the issues directly, transform performance and build a better Thames Water for all of our stakeholders. I brought on board an almost entirely new Executive team and moved the business closer to customers by establishing separate operational teams in London and the Thames Valley. One year into the turnaround, we have made good progress in fixing the basics and tackling the structural challenges in our business as well as laying the foundations for our long-term recovery.

"However, everyone at Thames is aware that we’re only at the start of our journey and there remains a huge amount to be done and delivered. We're also aware that none of the programme can be delivered without significant capital investment. With this new, substantial equity investment programme our shareholders are both underpinning the investment vital for our improvement and also expressing their confidence in the long-term outlook for Thames Water. We warmly welcome their continued support.

"This equity investment programme is a major milestone in our recovery plan. It gives the capital to invest, that will match the passion and commitment that exists throughout Thames, to improve our operations, improve outcomes for our customers and enhance our environment. I look forward to working closely with the Board, our shareholders and Team Thames as we work together to deliver the turnaround plan and develop our plans for PR24, which will be the next step on our journey."
