ULEZ Boundary & UK Clean Air Zones

This interactive map shows the approximate boundary of London's Ultra Low Emission Zone (ULEZ), together with other Clean Air Zones (CAZ) and Low Emission Zones (LEZ/ZEZ) in cities such as Birmingham, Bristol, Bradford, Sheffield, Glasgow, Edinburgh and Aberdeen.

You can pan and zoom around the UK; the map allows some space around the country but is still roughly limited to the wider UK region so you don't get completely lost.

This map is for general guidance only. For the official and most up-to-date information, always check the UK government Clean Air Zone service and the relevant local authority websites for each Clean Air Zone or LEZ/ZEZ.

Map data © OpenStreetMap contributors • Boundary data © TfL / Greater London Authority (where applicable) • Clean Air Zone / LEZ boundaries based on public local authority data (combined into active and inactive layers).

Couldn't load one or more boundary layers. The base map still works, but you may need to add or fix data/ulez-boundary.geojson, data/uk-caz-active.geojson and data/uk-caz-inactive.geojson on the server.
