Is my car ULEZ compliant?

What is ULEZ and where does it apply?

ULEZ stands for Ultra Low Emission Zone. It is a charging zone in London designed to reduce air pollution by discouraging the most polluting vehicles. If your vehicle does not meet the required emissions standard, you pay a daily charge to drive inside the zone.

The zone now covers all London boroughs, extending out to the edge of Greater London but not including the M25 itself. It operates 24 hours a day, every day of the year except Christmas Day. The charge applies once per day no matter how many times you enter, exit, or move around the zone that day.

ULEZ is separate from the Congestion Charge, which covers a much smaller central area and has its own rules. It is possible to be liable for both on the same journey, so it is worth understanding which zones your route crosses.

ULEZ is enforced by automatic number plate recognition cameras. There is no barrier and no toll booth, so it is entirely your responsibility to check whether you owe a charge and to pay it. Driving a non-compliant vehicle without paying leads to a Penalty Charge Notice.

What Euro standard does my car need to meet?

ULEZ compliance is based on Euro emissions standards, a series of EU limits that have tightened over the years. The higher the Euro number, the cleaner the exhaust emissions the vehicle was certified to produce when new.

For cars, the rule is straightforward. Petrol vehicles must meet Euro 4 or better, and diesel vehicles must meet Euro 6 or better. Because diesel engines emit more nitrogen oxides, diesels are held to a much stricter standard than petrols.

As a practical rule of thumb, most petrol cars first registered from January 2006 meet Euro 4, and most diesel cars first registered from September 2015 meet Euro 6. These dates are guides, not guarantees. Some models met the standard earlier, and a small number registered around the cut-off may not, so the registration date alone should never be treated as proof.

• Petrol car: must meet Euro 4 (broadly registered from 2006 onward)
• Diesel car: must meet Euro 6 (broadly registered from September 2015 onward)
• Motorcycles: must meet Euro 3
• Fully electric cars: compliant (though London charging rules for EVs are changing, so check current policy before travelling)
• Date of registration is a guide only, not confirmation

How do I check if my specific car is compliant?

The only reliable way to know is to check your exact vehicle rather than guessing from its age. Two cars of the same model and year can have different engines and therefore different Euro standards, so a registration-based check is far safer than a rule of thumb.

Transport for London runs the official ULEZ vehicle checker, which is the definitive source for whether a charge applies to your registration. It is free and tells you directly whether your vehicle meets the standard for the London zone.

You can also look at what we already hold on your vehicle. A free check on MOT Checkup returns the official DVLA and DVSA data we have, including fuel type, engine size, and CO2 figures, plus MOT and tax status. That context helps you understand your car before you confirm its emissions standard.

Be clear about the limits of any free data. Knowing the fuel type and year narrows down the likely Euro standard, but it does not confirm ULEZ compliance on its own. For a definitive yes or no for the London zone, always cross-check the official TfL checker for your registration.

What is the charge, and what is exempt?

If your vehicle is non-compliant and not otherwise exempt, the ULEZ daily charge for cars, vans, and motorcycles is £12.50. You pay it for each day you drive inside the zone. Larger vehicles such as lorries, buses, and coaches fall under a separate, higher Low Emission Zone charge rather than ULEZ.

If you do not pay, you will receive a Penalty Charge Notice. The penalty is far higher than the daily charge, though it is usually reduced if you pay it promptly, so it is always cheaper to pay the daily charge on time.

Some vehicles are exempt or benefit from a grace period. Vehicles registered with the DVLA in the disabled or disabled passenger vehicle tax class currently have a grace period exempting them from the charge until October 2027, provided the tax class does not change. Certain historic vehicles over 40 years old in the historic tax class, and some specialist vehicles, are also treated differently.

• Daily charge for non-compliant cars, vans, and motorcycles: £12.50
• Operates 24/7 every day except Christmas Day
• Penalty Charge Notice issued for non-payment (much higher than £12.50, often reduced if paid quickly)
• Disabled and disabled passenger vehicle tax classes: grace period to October 2027
• Historic vehicles (40+ years, historic tax class): generally exempt
• Always confirm your own status, as exemptions and grace periods change

ULEZ versus other UK Clean Air Zones

ULEZ is London's scheme, but several other UK cities run their own Clean Air Zones, and the rules are not identical. If you drive outside London, do not assume the London standard or charge applies.

Clean Air Zones operate in cities including Birmingham, Bristol, Bath, Sheffield, Bradford, Portsmouth, Tyneside (Newcastle and Gateshead), and Sheffield, among others. They use a national framework of classes, lettered A to D, that determines which vehicle types are charged. Many of these zones do not charge private cars at all and instead target older taxis, vans, buses, and lorries.

The underlying Euro standards are broadly similar to ULEZ, generally Euro 4 for petrol and Euro 6 for diesel, but the charge amounts, which vehicle types pay, and the exact boundaries differ from city to city. Scotland also operates Low Emission Zones in cities such as Glasgow and Edinburgh, which can ban non-compliant vehicles outright rather than charge them.

Before any trip into an unfamiliar city centre, check that specific zone's rules. The safest approach everywhere is the same: find your car's Euro standard, then confirm it against the rules for the zone you are actually driving in. To get started, run a free check on your registration with our ULEZ checker to see the vehicle data we hold and head straight to the official emissions check.
