The Drinking Water Inspectorate, part of Defra, has published the second 3-yearly report on the quality of drinking water supplies in England, covering 2020 to 2022. It summarises the quality of public supplies and the largest private supplies serving more than 5,000 consumers or 1,000 cubic metres (m3) a day. The Drinking Water Inspectorate regulates drinking water quality in England.

This report demonstrates the high quality of drinking water in England. Of the many thousands of samples taken by water companies (water supply licensees and wholesale licensees) during 2020 to 2022, 99.98% of public supplies met the regulatory standards. Every sample that did not meet the standards was investigated and, where required, actions were put in place to protect consumers and prevent recurrence.
