The ULEZ initially covered the same central area as London's Congestion Charge zone but has now been expanded to cover all parts of the city within the North and South Circular roads. It takes in all parts of the city from Haringey in the north and Southwark in the south to Newham in the east and Ealing in the west.

What area will the new ULEZ cover?

On 25 October 2021, the Ultra Low Emission Zone (ULEZ) expanded from central London up to (but not including) the North Circular and South Circular roads. The new zone is 18 times the size of the central London zone and now covers 3.8 million people.

What areas are affected by ULEZ?

The ULEZ currently covers most of Central London, including the City and Westminster areas, and operates 24 hours a day, seven days a week, 365 days of the year. It will be expanded to cover most of Greater London from October 25 2021, accounting for the entire area between the North and South Circular roads.
