Tories pledge to scrap outer London Ulez

In August, Ulez was expanded to include outer London. It previously covered the area between the A406 North Circular and A205 South Circular roads.

Drivers of the most polluting vehicles must pay a £12.50 daily charge if they use almost any road within Greater London, on top of any tolls or the inner London Congestion Charge.

Drivers of Ulez-compliant vehicles do not have to pay the fee.

In London’s mayoral election last month, Conservative candidate Susan Hall also pledged to scrap the expanded zone.

The first assessment of the effect of Ulez – expanded to outer London – has yet to be released, with a spokesman for the Mayor of London Sadiq Khan stating that it would come after the mayoral election.

Last year, research published by the University of Bath said the 2008 low emission zone (Lez) for lorries and the 2019 Ulez had both produced health and economic benefits for the city.

Ulez proved controversial when Mr Khan fronted its expansion to cover outer London boroughs, including areas such as Bromley, Croydon, Heathrow Airport and Wembley.

Vandals have damaged Ulez cameras and signage, while anti-Ulez protesters have gathered on several occasions in Parliament Square, Trafalgar Square and Strand.
