Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to improve public awareness of drinking water (a) safety and (b) quality standards.

The Government is committed to ensuring a high level of protection for human health and the environment. Drinking water quality in England is exceptionally high and among the best in the world; the UK was ranked in the top 8 countries globally for drinking water safety in the 2024 Environmental Performance Index.

Public drinking water compliance with the Water Supply (Water Quality) Regulations 2016 has been consistently high for years. The most recent published figures show 99.97% compliance rate compared with between 98-98.5% in the early 1990s.

The Drinking Water Inspectorate (DWI) publishes advice on drinking water quality safety and standards online. In December 2024, the DWI published a report, with recommendations, on drinking water standards by an advisory group of specialists with wide-ranging technical expertise. Defra and the DWI will work together to consider potential regulatory updates to England’s drinking water quality legislation based on these recommendations.
