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

To ask the Secretary of State for Environment, Food and Rural Affairs, when the table with health advice for each band of the Daily Air Quality Index was removed from the DEFRA UK AIR webpage; and for what reason.

The table setting out health advice for each band of the Daily Air Quality Index (DAQI) was removed from the UK-AIR DAQI webpage in December 2025 as part of the ongoing migration of air quality information from UK-AIR to newer digital services.

The change was made to improve the accessibility, usability and maintenance of air quality information, it occurred in parallel with updates to the DAQI health advice based on advice made by Committee on the Medical Effects of Air Pollutants (COMEAP) to the Air Quality Information System (AQIS) review, ensuring that the information provided to the public reflects the latest clinical evidence.
