ULEZ & Clean Air Zones
Compliance Check
Is my car ULEZ compliant?

Expert Written • 5 industry sources
Your car is likely ULEZ compliant if it is a petrol registered after 2006 or a diesel registered after 2015. The fastest way to confirm is to enter your number plate into the free TfL vehicle checker, which gives an instant pass or fail result.
The ULEZ Emission Standards
Petrol threshold:
Petrol cars must meet Euro 4 standard, which generally applies to vehicles first registered from January 2006 onwards.
2
Diesel threshold:
Diesel cars must meet Euro 6 standard, which generally applies to vehicles first registered from September 2015 onwards.

Registration year is a guide, not a guarantee:
Some cars registered close to those dates may not meet the standard, and a small number of older vehicles do comply. Always confirm using your number plate.

Check before every trip into London:
The ULEZ covers all roads within the Greater London boundary. Non-compliant cars face a £12.50 daily charge, with a £180 penalty charge if unpaid.

Other UK Clean Air Zones also apply:
Birmingham, Bristol, Bath and other cities operate their own Clean Air Zones with separate compliance rules. GOV.UK lists every active CAZ and links to local checkers.

What the Euro Standards Mean in Practice
Euro numbers indicate cleanliness:
Higher Euro numbers mean tighter limits on NOx and particulate emissions. Euro 6 diesel produces roughly 96% less NOx than a Euro 1 equivalent.

Hybrids and EVs always comply:
Battery electric vehicles are exempt from ULEZ charges. Most petrol hybrids registered after 2006 also meet the Euro 4 threshold.

Save Money Whether You Comply or Not
Compliant drivers still pay for fuel:
Passing the ULEZ check does not mean you should overpay at the pump. Prices across London stations vary by up to 10p per litre.
