Tap running water
We've had lots of questions about fluoride from our customers, so we've pulled all the information into one place.

The biggest question we get is do we add fluoride to the water supply?


The answer is yes, we do.


We add fluoride to around 40% of the water supply in the North East.


The decision on if, when and where it’s added is made by The Department for Health and Social Care in Government and the Local Authorities in our areas and we act under instruction from them.

Why is fluoride added?

It’s added to help prevent tooth decay and improve oral health.

The areas where the water supply is fluoridated include:


Chester le Street








You can check to see if the water supply where you live is fluoridated by clicking / entering your postcode within Your local area of our website. From here, download the water quality report to view the information about fluoride. 


For more information on fluoride schemes in your area then contact your Local Authority or The Department for Health and Social Care in Government.
