To help improve air quality, an Ultra Low Emission Zone (ULEZ) operates 24 hours a day, 7 days a week, every day of the year, except Christmas Day (25 December), within the same area of central London as the Congestion Charge.
Most vehicles need to meet the ULEZ emissions standards or you must pay a daily charge to drive inside the zone:
From 25 October 2021, the ULEZ is expanding from central London to create a single, larger zone up to, but not including, the North Circular Road (A406) and South Circular Road (A205). Find out how to prepare for the ULEZ expansion.
