The first stage of London’s Ultra Low Emission Zone (ULEZ) came into force on the 8 April 2019, all vehicles entering the ULEZ will need to meet Euro 6/VI diesel standard or Euro 4/IV petrol standard. Any vehicles which do not meet these standards will be charged. The ULEZ covers the same area as the congestion charge zone.

The ULEZ will then expand up to but not including the North and South circular roads from 25 October 2021.

The Low Emission Zone (LEZ) will be tightened up for buses, coaches and lorries from 26 October 2020, any vehicles entering the London-wide LEZ will need to meet Euro VI emissions limits.
