How It Works

The Ultra Low Emission Zone (ULEZ) covers all of Greater London. Vehicles that do not meet the emission standards are charged £12.50 per day. For most petrol cars, the standard is Euro 4 (generally vehicles first registered after January 2006). For diesel cars, the standard is Euro 6 (generally first registered after September 2015).

Motorcycles and mopeds must meet Euro 3 (generally first registered after July 2007). Vans, minibuses and specialist vehicles under 3.5 tonnes follow the same petrol and diesel standards as cars. Larger vehicles (over 3.5 tonnes, buses and coaches) are subject to the separate Low Emission Zone (LEZ) and must meet Euro VI standards.

You can check your vehicle's compliance by entering your registration number on the TfL vehicle checker. Non-compliant vehicles driving in the ULEZ face charges of £12.50/day plus a £160 penalty if not paid by midnight the following day (reduced to £80 if paid within 14 days). This calculator estimates your annual ULEZ costs if your vehicle is non-compliant.

Example: 2012 diesel car, driving in London 3 days/week

  1. Vehicle: 2012 diesel (Euro 5, non-compliant)
  2. Daily ULEZ charge: £12.50
  3. Weekly cost (3 days): £37.50
  4. Annual cost (50 weeks): £1,875
  5. Scrappage scheme payment (if eligible): up to £2,000
  6. Upgrading to compliant vehicle saves £1,875/year
