Tap water

Water quality

We constantly clean, disinfect and carefully test your drinking water to ensure before it makes the journey to your taps it’s safe for our seven million customers to use.

Occasionally, you may experience issues with your water, such as discolouration. Often this is harmless, with a simple explanation for the change and an easy way to resolve any issues. 

If your water looks unusual or has an abnormal taste or smell, there are some quick ways you can identify what's causing the problem and, in many cases, fix it yourself.
