ⓘ Ultra Low Emission Zone

The Ultra Low Emission Zone is a fee charged to the most polluting vehicles in Central London. Plans were laid out under Boris Johnson and introduced by Sadiq Khan on 8 April 2019. It led to the number of the worst polluting vehicles dropping from 35.600 to 23.000 and a 20% reduction in emissions in Central London. The zone will be expanded to cover the North and South Circular from October 2021.


1. History

Plans for an ultra–low emissions zone were under consideration since 2014 under Mayor Boris Johnson. In February 2017, Mayor Sadiq Khan announced plans to expand the Ultra Low Emission Zone ULEZ in April 2019 beyond Central London, one year ahead of schedule. Drivers do not pay both the ULEZ and the previous £10 T-charge, but they are still subject to the London Congestion Charge. The money raised from the ULEZ is invested in the transport network and improving air quality in London.


2. Introduction and effect

The zone was introduced in April 2019 and led to a 20% reduction in emissions by July 2019. The number of the worst polluting vehicles entering the zone each day dropped from 35.578, in March 2019, to 26.195 in April of the same year, after the charge was introduced. The number further dropped to 23.054 in July 2019. The proportion of vehicles which complied with the standards rose from 61% in March 2019 to 74% in September 2019.

The total number of vehicles entering Central London each day also dropped from over 102.000 in February 2017 to 89.000 in April 2019.


3. Reaction

The Ultra Low Emission Zone has been described as one of the most radical anti-pollution policies in the world. A poll in April 2019 by YouGov found that 72% of Londoners supported using emissions charging to tackle both air pollution and congestion. However, the Federation of Small Businesses said that many small firms were "very worried about the future of their businesses" as a result of the "additional cost burden".


4. Current charging scheme

The £12.50 charge applies 24 hours a day every day of the year, and is based on European emission standards:

  • Petrol cars and vans that do not meet Euro 4 standards vehicles pre-2006
  • Buses, coaches and lorries must meet or exceed the Euro VI standard or pay £100 a day
  • Diesel cars and vans that do not meet Euro 6 standards vehicles pre-2015
  • Motorbikes that do not meet Euro 3 standards pre-2007 vehicles

All road charging schemes in London including the ULEZ and Congestion Charge will be suspended for an unknown period of time from 23 March 2020 due to the Covid-19 pandemic.


4.1. Current charging scheme Exemptions

Residents of the zone will not pay the charge until October 2021 as long as they are registered for the residents Congestion Charge Discount and meet the T-charge standards. Vehicles in the "disabled" tax class are also exempt from the charge, as are London-licensed taxis, private hire vehicles which are wheelchair accessible and historic vehicles over 40 years old. There are also exemptions for agricultural vehicles, military vehicles, certain types of mobile cranes and non-road going vehicles which are allowed to drive on the highway e.g. excavators.


5. Future expansion

The zone will be extended to the North and South Circular from 2021 so that it would cover an area containing 3.8 million people. Once the zone is expanded, an estimated 100.000 cars, 35.000 vans and 3.000 lorries will pay the charge daily.
