Low Emission Zone

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.

The LEZ is separate from the Ultra Low Emission Zone (ULEZ) which is in place in central London and operates 24 hours a day, every day of the year except Christmas Day.

Tougher LEZ emissions standards for heavy diesel vehicles will come into force from 1 March 2021.

This was postponed to give affected businesses more time to meet the new standards as they face intense demands from the coronavirus pandemic.
