Emissions standards

Vehicles need to meet the LEZ emissions standards based on vehicle type and the type of emission.

Current LEZ emissions standards set a limit for how much particulate matter (PM) - very fine particles of pollutants - a vehicle can emit. From 26 October 2020 the standards for heavy vehicles will also set a limit for nitrogen oxides (NOx) which form harmful nitrogen dioxide (NO2) in the atmosphere.

PM can contribute to asthma, heart and lung disease, other respiratory illnesses and even early death. Breathing in high levels of NO2 over a long period of time is associated with an increase in symptoms of bronchitis in asthmatic children and reduced lung development and function.  

From 26 October 2020, LEZ standards will be:

  • Euro VI for buses and coaches over 5 tonnes, lorries and other specialist vehicles over 3.5 tonnes. This is the same as the ULEZ standard - the separate daily ULEZ charge will no longer need to be paid for vehicles meeting this standard
  • Euro 3 for larger vans and minibuses - the same as the current LEZ standard

If you drive a larger van or minibus within the ULEZ area from 8 April 2019, you will need to pay the ULEZ charge if you do not meet the ULEZ standard of Euro 4 petrol/Euro 6 diesel.

Meeting the standards

Your vehicle registration document (V5C) will help identify your vehicle's Euro emission standard.

The LEZ is enforced based on declared emissions of the vehicle rather than age, but Euro VI engines are generally those registered with the DVLA after 2014.

Vans and minibuses registered on or after 1 January 2002 will meet the existing Euro 3 emissions standard, which is not changing.

Vehicles which meet the ULEZ standards will already meet the tighter LEZ standards.

How charges and penalties will change

From 26 October 2020

  • Does not meet Euro VI - you will need to pay a daily charge of £100
  • Does not meet Euro IV PM standard - you will need to pay £300
  • Meets Euro VI - you will no longer have to pay the separate ULEZ charge

If you drive a larger van or minibus within the LEZ and it:

  • Does not meet Euro 3 - you will need to pay a daily LEZ charge of £100
