London-wide Ultra Low Emission Zone Expansion 2023

To help clear London's air and improve public health, the Ultra Low Emission Zone (ULEZ) is expanding across all London boroughs from 29 August 2023.

The current ULEZ covers inner London up to (but not including) the North and South Circular Roads.

The new boundary will be the same as the existing London-wide Low Emission Zone.
