The Low Emission Zone (LEZ) operates to encourage the most polluting heavy diesel vehicles driving in London to become cleaner. The LEZ covers most of Greater London and is in operation 24 hours a day, every day of the year.
From 8 April 2019 new, tighter emission standards - Ultra Low Emission Zone (ULEZ) standards - will affect petrol and diesel vehicles in central London. You may not meet the new ULEZ standards even if your vehicle currently meets the LEZ emission standards.
