The Ultra Low Emission Zone to clean up London’s air has been expanded.

The new zone covers up to, but not including, the North Circular and South Circular roads and is the largest zone of its kind in Europe.

It is estimated that 87 percent of vehicles travelling in the zone already meeting ULEZ standards, up from 39 percent in February 2017 when plans for expansion were first announced.

This high compliance rate also means that, as the scheme launches, it is expected only 110,000 vehicles each day are likely to need to pay the £12.50 charge.

There are a number of options to avoid paying the charge including walking, cycling, taking public transport, using shared mobility such as a car club or upgrading to a cleaner vehicle.

The scheme operates 24 hours a day, every day of the year except Christmas Day.
