What cars are exempt from the ULEZ? All electric cars are ULEZ exempt, along with all petrol cars which meet Euro 4 emissions standards and Euro 6 diesel models. All petrol models built after 2005 will be Euro 4 compliant, whereas diesel models built from 2015 onwards will be Euro 6 compliant.

In 2026, the most reliable way to check your vehicle's status is through the official Transport for London (TfL) "Check Your Vehicle" website, where you enter your Number Plate (VRM). The Ultra Low Emission Zone (ULEZ) standards in 2026 require petrol cars to meet Euro 4 standards (generally those registered after 2005) and diesel cars to meet Euro 6 standards (generally those registered after September 2015). If your car does not meet these criteria, you are required to pay a daily charge of £12.50 to drive anywhere within Greater London. In 2026, the zone is enforced by a massive network of ANPR (Automatic Number Plate Recognition) cameras. If you drive a non-compliant vehicle and fail to pay the charge by midnight on the third day following the journey, you will receive a Penalty Charge Notice (PCN). For international visitors or those with non-UK plates, you must manually register your vehicle with TfL's partner, EPC plc, to prove compliance and avoid automatic fines.

To determine if your car is compliant with London's Ultra Low Emission Zone (ULEZ) in 2026, the most reliable method is to use the TfL (Transport for London) vehicle checker website. You simply enter your vehicle's registration number (number plate), and the system will cross-reference it with DVLA records. Generally, the standards are: Petrol cars must meet at least Euro 4 standards (usually cars registered after January 2006) and Diesel cars must meet Euro 6 standards (usually registered after September 2015). Most Hybrid and Electric vehicles are automatically compliant, though some older hybrids might still trigger a charge if they don't meet the specific Euro rating. In 2026, the ULEZ covers the entire Greater London area, and driving a non-compliant vehicle results in a daily charge of £12.50. If you fail to pay by the third day after your journey, you will receive a Penalty Charge Notice (PCN) of £160 (reduced to £80 if paid within 14 days). Always check before you drive, as the ULEZ cameras use ANPR technology to scan every car that enters the zone.
