What Cars Are ULEZ Compliant? A Complete Guide
If you are wondering what cars are ULEZ compliant, the answer depends on your vehicle's emissions standard rather than its age or where it was registered. The Ultra Low Emission Zone (ULEZ) is designed to clear the air by encouraging the use of cleaner vehicles.
Checking if your vehicle meets these standards is simple, free, and provides peace of mind before you travel.
What Is the ULEZ?
The ULEZ (Ultra Low Emission Zone) is an area where vehicles must meet strict exhaust emission standards or pay a daily charge to drive within the zone. The goal is to improve public health by reducing harmful emissions.
Operates 24/7: The zone is active every day of the year
Daily Charges: If your vehicle is non-compliant, a charge applies for every day it is driven within the zone.
Resetting at Midnight: The charge period runs from midnight to midnight.
Where Are ULEZ Zones?
Currently, the ULEZ covers all boroughs within Greater London, extending up to (but not including) the M25. While you don’t need to live in London to be affected, anyone visiting or commuting in these areas must ensure their vehicle is compliant.
While Leicester does not currently operate a ULEZ, many of our customers regularly travel to London or other cities with Clean Air Zones (CAZ) like Birmingham. Choosing ULEZ compliant cars is a smart, future-proof way to ensure you can travel anywhere in the UK without unexpected costs.

What Happens If Your Car Is Not ULEZ Compliant?
ULEZ Daily Charges
If your vehicle doesn't meet the standards, you must pay a £12.50 daily charge. This applies to cars, motorcycles, and smaller vans.
ULEZ Penalty Charges
Failing to pay the daily charge can result in a Penalty Charge Notice (PCN). In 2026, the penalty is typically £180, though this is reduced to £90 if paid within 14 days. It is always more cost-effective to check your compliance in advance.
Which Cars Are ULEZ Compliant?
Understanding which cars are ULEZ compliant comes down to their "Euro" emissions rating.
Petrol Cars
To be a ULEZ compliant car, a petrol vehicle must generally meet Euro 4 standards. Most petrol cars registered after January 2006 meet this requirement, though some compliant models were available as early as 2001.
Diesel Cars
When asking what diesel cars are ULEZ compliant, the rules are stricter. Diesels must meet the Euro 6 standard. This usually applies to cars registered from September 2015 onwards. This is the most common area of confusion for drivers, as many relatively modern diesels still fail to meet this threshold.
Hybrid, Plug-In Hybrid & Electric Cars
Electric Vehicles: These are fully compliant and exempt from ULEZ charges.
Hybrids: Most petrol hybrids are compliant as they meet Euro 4 standards, but always double-check the specific model.

What Year Cars Are ULEZ Compliant?
Many people ask what year cars are ULEZ compliant, but the registration year is only a guide:
Petrol: Generally 2006 onwards.
Diesel: Generally September 2015 onwards.
Because some manufacturers met these standards early, and others sold older stock late, the year on the plate isn't definitive, so its always best to check.
Examples of ULEZ Compliant Cars
While compliance depends on the specific engine, here are some popular ULEZ compliant cars for sale often found in our showroom:

How to Check If a Car Is ULEZ Compliant
The most reliable way to check if a car is ULEZ-compliant is to use the official Transport for London (TfL) checker.
Visit the TfL website.
Enter your vehicle registration number.
Confirm the country of registration.
Knowing how to check if a car is ULEZ compliant before you travel, or before you buy, is the best way to avoid fines.
Are Older Cars Ever ULEZ Compliant?
Some older petrol cars (pre-2006) were built to Euro 4 standards early. Never assume a car is non-compliant based on age alone; always run a check.
Servicing & MOTs for Emissions and ULEZ Readiness
Maintaining your vehicle’s efficiency is key to ensuring it remains as clean as possible on the road. Regular servicing plays a vital role in this by keeping your engine running at peak performance, which helps maintain lower emissions levels over time.
During an annual MOT, the emissions test acts as a crucial health check, highlighting potential issues with your exhaust or fuel system before they become costly repairs. It is important to clarify, however, that passing an MOT does not automatically mean your car is a ULEZ compliant car, as compliance is determined by the vehicle's original Euro standard. By choosing preventative servicing rather than reactive repairs, you can ensure your vehicle stays reliable and efficient.
Buying a ULEZ Compliant Used Car
If your current vehicle isn't compliant, upgrading to a used ULEZ compliant car is often the most practical solution. The Sturgess Stamped programme ensures our used cars undergo rigorous inspections and come with a 3-month warranty for total peace of mind. We also offer flexible HP and PCP finance options to help you make the switch.
