Water quality

We work hard to ensure 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.
