We work hard to improve the quality of your drinking water.
Every year we carry out more than 500,000 tests. We take samples from our water mains and pipes, as well as from customers’ taps.
Since 2010, more than 99.95% of tests taken from customers’ taps met the standard required by UK and European legislation.
If you want to check out the water quality in your local area, all you need is your postcode.
Our range of water quality topics

Our water passes through soft chalky limestone. That’s why our water is hard.

There could several reasons why your water is a different colour or taste.
