Thames Water

About the Company

We are the UK’s biggest water and sewerage company with around 15 million customers across London and the Thames Valley. You would be joining a company with an amazing history and an exciting future.

We provide clean and take away waste water for almost 25 per cent of the UK population every day – that’s more than 11,000 Olympic size swimming pools worth of clean water and 16,000 pools of waste.

We will not compromise on standards which is why we carry out more than 400,000 tests per year on our drinking water. We continue to invest and this year will be spending more than £1 billion to improve our networks and infrastructure – our pipes, sewerage treatment and clean water treatment plants, which are some of the biggest and most advanced sites in Europe. And we will spend the same again next year in our challenge to make sure that if our customers had a choice, they would choose Thames Water.

Planning for the future is a key part of our strategy and we already generate enough electricity to power more than 55,000 homes. We also understand the importance of speaking to our youngest customers through our sustainability and education programs in schools and effectively manage and maintain a number of nature reserves.

Above all this, Thames Water values its staff as number one and we can now look forward to welcoming you to our team.
