The London Ultra Low Emission Zone expands, the Portsmouth Class B Clean Air Zone is due to launch next month, while Sheffield’s one gets approval.

London ULEZ

From Monday 25 October 2021 the London ULEZ has expanded and now includes all areas within the North and South Circular roads. Most diesel cars first registered after September 2015 and most petrol cars registered from 2005 onwards are exempt.

TfL has said four out of five vehicles registered within the new zone are compliant but it estimates 130,000 are not. Drivers who do not comply with minimum emissions standards will have to pay £12.50 daily to drive in the zone, those who fail to pay face being handed a Penalty Charge Notice of £160, reduced to £80 if paid within a fortnight.


Portsmouth’s Class B Clean Air Zone is due to launch on 29 November 2021. Non-compliant vehicles are bus, coach, taxi, private hire vehicle or heavy goods vehicles (HGVs) that do not meet Euro 6 standards for diesel vehicles and do not meet Euro 4 emissions standards for petrol vehicles.

You can keep up to date with news on the Portsmouth CAZ via the Portsmouth Cleaner Air website.

The Sheffield Council has agreed to introduce a Clean Air Zone from late 2022. Just like in Portsmouth, vehicles will need to meet Euro 6 diesel or Euro 4 petrol emissions standard to avoid the charge, but private cars will be exempt. The Clean Air Zone will start on the Sheffield Parkway and goes around the city

Charges will apply to drivers of vehicles which do not meet these emission standards:

  • Taxis (Hackney Carriages and Private Hire) which are Euro 6 Diesel or Euro 4 Petrol
  • LGVs (vans, campervans and pickup trucks) and Minibuses which Euro 6 Diesel or Euro 4 Petrol
  • Buses and coaches with Euro 6 Diesel
  • HGVs with Euro 6 Diesel
