Every child in London is breathing toxic air, mainly caused by road vehicles. Led by the Mayor, Sadiq Khan, we are committed to helping Londoners breathe cleaner air.

As part of this commitment, we will operate the Ultra Low Emission Zone in central London 24 hours a day from 8 April 2019.

How to meet air quality standards

If you drive in London, you may have to pay one or more of the charges aimed at improving our air quality. Find out what charges may apply by the type of vehicle you drive, or learn more about each charge.

Drivers going into central London may also have to pay the Congestion Charge.

Air quality consultation

Our latest consultation on proposals to clean up London's air - including an expansion of the ULEZ - closed on 28 February 2018.

The consultation report will be published later in 2018 on our ULEZ/LEZ consultation page.
