Question to the Department of Health and Social Care:

To ask His Majesty's Government what assessment they have made of the cost to water companies of adding fluoride to the water supply.

My Rt Hon. Friend, the Secretary of State for Health and Social Care is responsible for reimbursing water undertakers for the reasonable costs associated with water fluoridation schemes. In the financial year 2023/24, these costs were £4,109,521 in revenue and £348,351 in capital for the estimated six million people in England covered by such schemes.
