Our mission, purpose and values

Our mission is to support the lives of people and the places they love for generations to come by bringing water to life. And our purpose isn’t just what we believe in, it’s what we do every day. Continuing to ensure we’re doing the right thing for our customers and stakeholders, delivering fresh clean drinking water, protecting the environment and continuing to innovate will help us look after the South West now and into the future.

We know that it’s not only what we do, but how we do it that’s really important for our customers, colleagues, communities and the environment. That’s why we’re focused on living our values, every day.



We’re trusted by our customers and stakeholders to deliver the services that households and businesses depend on in a fair, responsible and sustainable way.



We work collaboratively with customers, regional organisations and agencies, suppliers and other stakeholders to identify and implement new and improved ways of working.



Our responsible leadership, governance and decision-making processes support the delivery of high quality services which bring positive social, economic and environmental benefits to the regions we serve.



To continually improve our services, we support a culture of innovation and utilise new technologies in order to better meet our customers’ needs and priorities.

The environment

Our commitment to Net Zero

We have ambitious plans to transform how we produce and use energy. Our mission? To bust our operational carbon emissions and hit Net Zero by 2030. For us, that means cutting up to 100,000 tonnes in carbon emissions.

From increasing our energy efficiency programme to decarbonising our fleet, purchasing 100% renewable electricity to planting 250,000 trees by 2025, we’re focused on how we create and use energy in the most efficient way – and how we can innovatively use our local environment to reverse carbon emissions for decades to come.

From championing innovative partnerships with wildlife charities to reducing pollution, we take our guardianship of the natural world very seriously.

Through our community initiatives we support local projects that matter most to our customers. Our community funds support the wellbeing of people, improve and protect our local environment, and champion new and innovative water-saving projects across the South West. We also support the communities we serve with our Give an Hour employee volunteering scheme.
