Water quality

We work hard to ensure the quality of your drinking water.

Every year we carry out more than 500,000 tests, taking samples from water mains, pipes and properties.

As part of our program, we carry out sampling from customers’ taps chosen at random in compliance with the Water Quality Regulations.

If our technicians arrive at your property to take a sample, they'll show you their ID card and explain what happens next.

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.
