We do not add – and currently have no plans to add – fluoride to the water we supply.

The water we supply naturally contains between 0.1 and 0.3 mg/l (parts per million) of fluoride, which is not removed during treatment. The maximum concentration of fluoride allowed in the water is 1.5 mg/l. There is no minimum limit.

In the past, local health authorities could ask water companies to artificially fluoridate the water supply, but the companies could refuse. Legislation in 2008 gave the authorities the power to compel companies to fluoridate the water supply, after public consultation.

Fluoride is a health issue. We believe that health professionals should make decisions about health measures, not water companies.
