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 keeps the North West moving. From morning brews to hospital wards, school runs to factory floors, it's an essential part of everyday life and the businesses that power our region. At United Utilities, we supply 1.8 billion litres of clean water to 8 million people and 200,000 businesses across the North West every day. We also take away and treat wastewater, helping to protect public health, support communities and care for the environment we all share. But our role goes beyond the services we provide. Behind every drop of water is a vast network that spans the North West. From 184 reservoirs and 57,000 hectares of catchment land to 575 wastewater treatment works and more than 42,000 km of water pipes, we're responsible for infrastructure that stretches from Cumbria to Cheshire and supports millions of people every day. As our region faces some of its biggest challenges, from population growth to increasingly extreme weather, we're helping build a water system that's ready for the future. That's why we're investing more than £13 billion over the next five years, the biggest investment in our network for more than a century. This includes our Big North West Upgrade, one of the UK's largest infrastructure programmes, helping to modernise the network that millions of people rely on every day. Because this isn't just about infrastructure. It's about supporting communities, helping businesses thrive, protecting the environment and ensuring the North West has a resilient water system for generations to come. Because when you invest in water, you're investing in everything. And if you've ever wondered where your money is going, the answer is simple: It's going everywhere. Into communities. Into jobs and skills. Into rivers, coasts and the environment. Into homes and businesses. Into a water network that's ready for whatever the future brings.

Anglian Water supply water and water recycling services to more than six million domestic and business customers in the east of England and Hartlepool. Our services are at the heart of every single family and community in our region. We clean water to the highest standard, deliver it to millions of homes, and carefully manage it to ensure it never runs out. We’re the largest water and water recycling company in England and Wales by geographic area. We’re also one of the driest regions in the country, with just 600 millimetres of rain each year, on average a third less than the rest of England. In fact some areas have a lower annual rainfall than Jerusalem. That’s why it’s vital that we look after the water that we’ve got.
