Air quality reports and data
We publish air quality reports that review air quality across Hillingdon, highlight key issues or developments, and track progress of improving air quality.
Our reports are publicly available and can be accessed by anyone, including residents, applicants of proposals for development, researchers, scientists and other organisations with an interest in local air quality.
Annual status reports
We are required by Mayor of London to produce an Annual Status Report that summarises local air quality monitoring results and the actions we take where national air quality objectives are not met.
