We do not add fluoride to the water we supply.  Fluoride can occur naturally in some water supplies but it is normally only present at low levels.

You can check this naturally occurring background level of fluoride in your drinking water using the search facility below, which provides general information on the fluoride levels of the water supplied to more than 80,000 postcodes in our area.
