To ask His Majesty's Government what assessment they have made of the quality of Thames Water's supply and its potential impact on health and well-being of children in the area.
- Answer

Thames Water achieved 99.97% compliance with the drinking water standards in 2025. Customers should have confidence that their drinking water is safe.

Where there is an unmanaged or unmitigated risk to public health, the DWI will take appropriate enforcement action to protect the public.
