ULEZ Checker - Ultra Low Emission Zone

How does carwow’s ULEZ checker work?

carwow’s free ULEZ checker uses your vehicle’s registration to tell you if your vehicle is compliant and whether you’ll need to pay the £12.50 ULEZ charge. The ULEZ expanded in August 2023 and now covers most of London within the M25.

Our tool also shows you London’s Congestion Charge Zone so you can find out if you’ll need to pay an additional £15 daily charge to drive into certain areas of the capital.

What is the London ULEZ? 

The London Ultra-Low Emissions Zone (ULEZ) was brought in as a way to reduce the number of high-polluting cars entering the capital,. It used to stretch as far as the North and South Circular roads, but expanded on 29 August 2023, and now covers almost all areas within the M25.

If your car isn’t ULEZ compliant, you’ll have to pay a fee to enter the ULEZ. It currently costs £12.50 for cars, motorcycles and vans, and £100 for larger vehicles such as trucks and coaches.

Is my car ULEZ compliant?

The Ultra-Low Emission Zone mainly targets older vehicles which pollute more. If you have a petrol engined car, it needs to meet Euro 4 emissions standards to be ULEZ compliant. Euro 4 was introduced on every car built from 2005 onwards. 

The rules are much tougher on diesel models, as they need to meet Euro 6 emissions standards to be exempt from ULEZ charges. Euro 6 covers all diesel cars built after 2015. 

Electric cars are also ULEZ exempt. If you’re looking to change your car for something ULEZ compliant, carwow can help. You can sell your old car, and get a great deal on a new car or browse our stock of used cars, all from the comfort of your home.


If your car isn’t ULEZ compliant, it’ll cost you £12.50 for cars, motorcycles and vans. Larger vehicles such as trucks or coaches which aren’t compliant will cost £100 to enter the ULEZ.

You can pay the ULEZ charge online via the gov.uk website. Simply enter your number plate and follow the instructions.

From 29 August 2023, the ULEZ was expanded and now covers almost all areas within the M25.

The ULEZ applies 24 hours a day, everyday of the year, apart from Christmas day.

The ULEZ is enforced using number plate recognition cameras throughout London. If you drive past one and your car isn’t ULEZ compliant, it’ll be logged and you have to pay the charge.

The ULEZ is clearly signposted as you enter the capital. Keep an eye out for the green signs with ULEZ written in a white circle.

All electric cars are ULEZ exempt, along with all petrol cars which meet Euro 4 emissions standards and Euro 6 diesel models.

All petrol models built after 2005 will be Euro 4 compliant, whereas diesel models built from 2015 onwards will be Euro 6 compliant.

The ULEZ was first expanded in 2021 to include everything within the North and South circular roads, and it was expanded again on 29 August 2023. The expanded ULEZ now covers areas up to Waltham Cross in the north, Upminster to the east, West Drayton and Longford to the west, and as far south as Coulsdon and Biggin Hill.
