Does your vehicle qualify for ULEZ exemption?

Emissions compliance is determined by European emissions standards (Euro status), not the fuel economy of your vehicle.

Euro 4+

Petrol Vehicles

Must meet Euro 4 standards. In practice, almost all petrol cars registered in the UK from January 2006 onwards meet this standard and are exempt.

🛢️Euro 6+

Diesel Vehicles

Must meet Euro 6 standards due to nitrogen oxide (NOx) limits. This generally includes all diesel cars registered from September 2015 onwards.

Zero Emission

Electric Vehicles (EV)

All battery-electric vehicles (BEVs) and hydrogen fuel cell cars are 100% exempt from all UK clean air zones and the London ULEZ.

Understanding London ULEZ & Clean Air Zone Rules

The Ultra Low Emission Zone (ULEZ) expanded in August 2023 to cover all 32 London boroughs within the Greater London Authority boundary, stretching out to the M25 motorway. Over 700 Automatic Number Plate Recognition (ANPR) cameras actively record registrations entering and driving within the zone.

Unlike the central London Congestion Charge (which only operates during peak daytime hours on weekdays and weekends), ULEZ operates 24 hours a day, 7 days a week, every single day of the year except Christmas Day (25 December).

If you drive a non-compliant vehicle across midnight, you will be liable for two daily charges (£25.00 total) because charges run on a calendar day basis (00:00 to 23:59).

Looking for cheaper motoring costs?

Beyond avoiding ULEZ penalty charges, fuel prices across London and the UK differ by up to 20p per litre between supermarket forecourts and branded motorway stations. Compare live forecourt rates with our UK Petrol & Fuel Price Tracker or search specifically for Diesel Prices Near Me to save money on every tank.

Frequently Asked Questions

How do I check if my car is ULEZ compliant?

Enter your vehicle registration number into Kermo's free ULEZ checker above. We inspect your vehicle's fuel type and Euro emissions standard directly against official DVLA specifications to determine whether you are exempt or subject to daily charges.

What are the emissions standards for London ULEZ?

To be exempt from the £12.50 daily London ULEZ charge, petrol cars and vans must meet Euro 4 emissions standards (mandatory on new cars from January 2006). Diesel cars and vans must meet Euro 6 emissions standards (mandatory on new cars from September 2015). All 100% electric vehicles are completely exempt.

Which other UK cities have Clean Air Zones (CAZ)?

In addition to London's ULEZ, Birmingham and Bristol operate Class D Clean Air Zones that charge non-compliant private passenger cars (£8/day in Birmingham, £9/day in Bristol). Sheffield, Bath, Bradford, and Newcastle operate Class C or B zones that charge commercial vehicles, taxis, and buses, while completely exempting private passenger cars.

Are hybrid vehicles exempt from ULEZ?

Hybrids are not automatically exempt. A hybrid must meet the standard for its combustion fuel type: a petrol hybrid must meet Euro 4, while a diesel hybrid must meet Euro 6. Most modern plug-in and self-charging hybrids meet these criteria.

What happens if I do not pay the ULEZ charge on time?

If you drive a non-compliant vehicle in the ULEZ and do not pay the £12.50 charge by midnight on the third day following your journey, Transport for London (TfL) will issue a Penalty Charge Notice (PCN) of £180, reduced to £90 if paid within 14 days.

Are historic classic cars exempt from ULEZ?

Yes. All vehicles constructed more than 40 years ago that are registered under the 'Historic' vehicle tax class with the DVLA are exempt from both London ULEZ and regional Clean Air Zones across the UK.
