Check air pollution at your address

A new interactive tool - - is a free public service from Central Office of Public Interest (COPI). Every UK address is searchable, with  air pollution data pulled from a national 20m/sq resolution model created by Imperial College London (ICL). To ensure accuracy, COPI sourced and mapped real world pollution levels recorded at more than 19,500 council monitors in every major town and city across the UK. The scientists at ICL were then able to calibrate to these real world levels - resulting in the most detailed and accurate national model ever created.

The pollution data provided are annual average levels in 2019: the last ‘normal’ year uninterrupted by travel restrictions or national lockdowns. Concentrations of three toxic pollutants are displayed: PM2.5 (fine particles with a diameter of 2.5 microns or less), PM10 (particles with a diameter of 10 microns or less) and NO2 (Nitrogen Dioxide).
