New Clean Air Zones in London, Portsmouth and Oxford

London’s Ultra Low Emission Zone (ULEZ) will be expanding in the coming weeks, Portsmouth are looking to schedule their CAZ for late November and Oxford will launch Britain’s first Zero Emission Zone (ZEZ) in February 2022.

London ULEZ expansion


London’s ULEZ first came into force in April 2019. The zone is in operation 24 hours a day, seven days a week, every day of the year (except Christmas Day).


At this current moment, the zone covers central London but from Monday 25th October, the zone will expand to encompass the areas between the North Circular Road and South Circular Road – but not the roads themselves.


Vehicles that will be affected are petrol cars and vans that aren’t up to Euro 4 standards, diesel cars and vans that don’t meet Euro 6 standards and motorbikes that don’t meet Euro 3 standards.


The current ULEZ charges will remain the same upon the expansion. For all the information regarding ULEZ payments, go to the link here.


Portsmouth Clean Air Zone


Portsmouth will be the 3rd area in the country to receive a CAZ. The new CAZ is likely to commence at the end of November.


39 Automatic Number Plate Recognition (ANPR) cameras were installed back in March and were set up across the area in preparation.



Any diesel vehicle that does not meet Euro 6 emission standards and petrol vehicles that don’t meet Euro 4 emission standards will be charged for driving through the zone.

Oxford Zero Emission Zone


Oxford will pilot the first ZEZ in the country in February next year. The ZEZ was approved in March and was set for an August 2021 launch but the deadline was put back to avoid disruption to struggling businesses post pandemic.


The new ZEZ will be in operation from 7am to 7pm, seven days a week. New Road, Bonn Square, Queen Street, Cornmarket Street, New Inn Hall Street, Shoe Lane, Market Street, Ship Street and St Michael’s Street are the roads that will be covered in the zone.


Ultra-low emission vehicles will be charged £2 per day, Clean Air Zone compliant vehicles will be charged £4 per day, mopeds & motorcycles will be charged £2 per day and vehicles not meeting any of these standards will be charged £10 per day.


All of these rates will change in August 2025. For all the details on the ZEZ go to the link here.
