The London Ultra low emission zone (ULEZ) made a big impact when it was implemented in April 2019, initially covering the same geographical area as the London Congestion charge Zone. Now, even more drivers are affected, as the zone has expanded to cover the entire area of London within the North circular and South circular roads.

Owners of affected automobiles have to pay a daily charge to drive into the zone, which, unlike the Congestion charge Zone, operates 24 hours a day, 365 days a year.

Euro 6 emissions standards: what do they mean for you?

The ULEZ was introduced in London to cut emissions of nitrous oxides and particulates in the city with the aim of improving air quality.
But what is the ULEZ charge, what area does it cover and which types of vehicle are affected? We answer these questions and more in our ULEZ guide below.
What is the ULEZ?
The Ultra low Emissions zone is an area of London where the most polluting vehicles must pay a levy in order to use the roads. The ULEZ charge initially replaced the previous T-Charge.
While at first the ULEZ covered the same area as the Congestion charge zone in central London, it expanded on Monday 25 October 2021 and now covers all areas inside the North and South circular roads.

The charge, which must be paid on top of the £15 daily Congestion Charge, is set at a conventional rate of £12.50 – although this varies depending on the vehicle – and is in effect 24 hours a day, seven days a week.
