Thames Water is the UK’s biggest water and wastewater services provider, providing 2.7 billion litres of drinking water and safely removing 4.6 billion litres of wastewater every day. Our people provide essential services around the clock to c.16 million customers across London, the Thames Valley, and surrounding areas. In 2025, we started the biggest upgrade to our network in 150 years, which will see a record-breaking investment of over £20 billion, fixing leaks, reducing pollution and protecting water quality, over the next five years. In 2024/25, we invested £2.2 billion, and we will continue to spend wisely on improving resilience, service, and efficiency, as well as provide more support for customers in vulnerable circumstances. We also have additional responsibilities to society and the natural environment. What we do and how we do it delivers significant public value, which is why we have ambitious plans to self-generate more of our own power, reduce our carbon emissions and increase biodiversity across our sites.

Water is wonderful. Without it we’d be lost. With it, everything’s possible. For every toothbrush, for every loo flushed. For the hot showers, the cool drinks, the cups of tea. But it’s not just at the heart of our homes. It’s at the heart of everything — our schools, our businesses, our hospitals. Saving lives, helping communities thrive. We’re Severn Trent, a diverse and amazing group of people who want to keep it that way. We bring you clean water and we take it away safely too. But it’s not just what we do — it’s how we do it: not just talking, but going over and above. Stepping up and rolling our sleeves up. It’s because we care. Not only about our water, but about our corner of the country. And we care for the amazing people who make all this possible. Don’t just take our word for it; we’re in the top 5% of utility companies worldwide for employee engagement, and we’re equally proud of our strong Glassdoor score — reflecting how much our people love working here. At Severn Trent, we do more, because we care.
