The Congestion Charge Zone covers most of central London including the City of Westminster, the City of London and parts of the London Boroughs of Camden, Lambeth and Southwark.

How do you know if you went through congestion zone?

If you've driven into the Congestion Charging zone there's no way to find out if your vehicle's number plate was recorded or not, other than wait to see if you get a letter or fine through the post.

Where is the new congestion zone?

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.
