If you live or work in Portsmouth, you've likely heard about the Clean Air Zone (CAZ) that came into effect on 29th of November 2021. This is an initiative by the council to improve air quality across the city and protect the health of its residents. The CAZ will have an impact on drivers as it will charge a fee for some vehicles entering the zone. Don't worry though; this guide is here to help you understand the new rules and how they might affect you.

Find out if your car will be subject to CAZ charges

The zone covers the whole of Portsea island, including Portsmouth, Southsea, and parts of Hilsea, Copnor, and Cosham. If you're driving in this zone, you'll need to check your vehicle to see if it's compliant. The fee only applies to older, more polluting vehicles, so if your car is less than a few years old, it's likely to be compliant. You can use the government's online checker to confirm this.

How do I know if my vehicle is compliant with the Portsmouth Clean Air Zone?

The charges for the Portsmouth CAZ are classified as Class B and therefore the moment applies to:

  • Taxis
  • Private Hire Vehicles
  • Buses
  • Coached
  • Heavy Goods Vehicles


If these vehicles do not meet the current emissions standards - Euro 6 emissions for diesel and Euro 4 emissions standards for petrol - then they will be charged for entering the zone.

What vehicles are exempt from the Portsmouth Clean Air Zone?

  • Motorcyles
  • Passenger Cars
  • Passenger vans

How much is the charge for a non-compliant vehicle?

The charge for non-compliant vehicles is £10 per day for taxis and Private Hire Vehicles, and £50 a day for HGVs (including non-compliant motorhomes), buses, and coaches. The charge applies 24 hours a day, seven days a week.

Why was Portsmouth Clean Air Zone introduced?

The council has introduced the CAZ to improve air quality for residents, and it's working hard to encourage people to use alternative modes of transport. Portsmouth has an excellent public transport network, including buses, ferries, and trains, and there are also cycling and walking routes across the city. The council has invested in new park-and-ride sites and is promoting car-sharing schemes. If you're a regular commuter, why not consider switching to a greener mode of transport?

Portsmouth's Clean Air Zone is a crucial step towards making the city a healthier and safer place to live in. Compliance with the clean air zone helps to reduce harmful emissions and protect the environment, especially in the inner city. By following the guidelines and ensuring that your vehicle meets the required standards, you can help to reduce air pollution and make a positive impact on your health and the environment.
