Thames Water is a leading utility company responsible for the supply and treatment of water and wastewater services in the UK. Serving over 15 million customers across London and the Thames Valley, the company operates in a highly regulated market overseen by Ofwat, the water services regulation authority. Thames Water manages an extensive infrastructure that includes 100 water treatment works, 35,000 km of pipe network, over 110,000 km of sewers, and more than 6,000 pumping stations. The company treats approximately 2,700 billion litres of water daily, equivalent to 1,080 Olympic swimming pools.

Thames Water's business model revolves around the provision of essential water and wastewater services, funded through customer bills that are regulated and reviewed every five years. This regulatory framework ensures that customer charges are fair while allowing the company to invest in infrastructure improvements and environmental protection initiatives. The company generates revenue primarily through these customer bills, which are set within the limits approved by Ofwat.

In addition to its core services, Thames Water is actively involved in large-scale improvement projects such as the Thames Tideway Tunnel, aimed at creating a healthier river environment for London. The company also focuses on sustainability and green recovery, investing in projects that help the region recover from the Covid-19 pandemic by enhancing services and creating new jobs.
