Water in your home

The water we supply is high quality but once it enters your home it can deteriorate due to the condition of pipes and fittings.



Our drinking water is of the highest quality but we know that customer's pipework can affect the quality of the water and also if we're working in your area, this can sometimes affect the appearance of your water. If you're concerned about your water quality or want to find out more, please see our factsheets below. 

We encourage anyone having work done on their household plumbing to use trusted and qualified plumbers, registered with the industry body WaterSafe. These plumbers have undergone specific training in the Water Fitting Regulations and Byelaws which are designed to keep customers’ drinking water safe and in the same quality condition that is supplied to their home or business.

For advice on keeping the water in your home at its best, download the water industry guide 'Looking after water in your home' - it includes everything from tips on tap hygiene to advice on safe water storage and how to prepare for winter.

There are regulations which specify how plumbing systems should be designed and maintained without causing contamination or wastage. For more information go to our Water Fittings Regulations section. You will also find details of the Water Industry Approved Plumbers Scheme, which contains a list of local plumbers who have a qualification in Regulations compliance.
