ULEZ & Clean Air Zone Checker
Is your car ULEZ compliant? Check in seconds.
Enter any UK registration. We pull the DVLA fuel type and first-registration date and tell you instantly whether the vehicle meets the Euro 4 (petrol) or Euro 6 (diesel) standard required for London ULEZ and the major UK Clean Air Zones.
How the ULEZ rules work
Generally any petrol car first registered from 1 January 2006. Most cars registered in 2005 also qualify if the manufacturer met the standard early.
Diesel cars and vans first registered from 1 September 2015. Older diesels typically pay £12.50 per day inside the London ULEZ.

Before you buy a used car
ULEZ compliance is one factor — finance, write-offs, mileage anomalies and theft markers matter just as much. Run a full vehicle history check or the free MOT history check before you put money down.
ULEZ compliance is inferred from DVLA fuel type and registration date. For official confirmation, use the TfL vehicle checker. Charges and zones change — figures are accurate at time of writing.
