Further details of the type of vehicles affected

Congestion Charge and T-Charge

Your vehicle may also be subject to the Congestion Charge and/or T-Charge. This is a daily charge for driving a vehicle within the charging zone between 07:00 and 18:00, Monday to Friday (two-wheeled vehicles are not affected).

Low Emission Zone (LEZ) compliance

Diesel lorries, buses, coaches, motor caravans, motorised horseboxes, larger vans, minibuses and other specialist vehicles must also comply with the emissions standards of the Low Emission Zone (LEZ). This covers most of Greater London and is in operation 24 hours a day, every day of the year.

If your vehicle meets the ULEZ emissions standards, it will also meet the LEZ emissions standards. You can check if your vehicle is affected with the LEZ vehicle checker.
