What is the Portsmouth Clean Air Zone?

The Portsmouth Clean Air Zone (CAZ) was launched on 29 November 2021 to help accelerate the uptake of low or zero-emission vehicles and reduce congestion in the city centre. The zone will charge high-polluting vehicles whose emissions contribute to over 50% of the city's air pollution.

Why does Portsmouth need a Clean Air Zone?

Portsmouth City Council was identified by the government as one of over 60 authorities that had excessively high air pollution levels.

To tackle this, a daily charge is issued to the most polluting vehicles for driving in the zone. For the Portsmouth charging CAZ, non-compliant vehicles are Heavy Goods Vehicles (HGVs), buses and coaches, taxis and private hire vehicles that:

  • Do not meet Euro 6 emissions standards (so are Euro 5 or older) if they are diesel.
  • Do not meet Euro 4 emissions standards (so are Euro 3 or older) if they are petrol.

Private cars, motorcycles and vans are not charged to drive in the zone.

Portsmouth CAZ Charge

What you need to know

Portsmouth is a Class B Zone, meaning buses, coaches, taxis, private hire vehicles and Heavy Goods Vehicles (HGVs) are all included in the charge.

Portsmouth CAZ operating times

Portsmouth's Clean Air Zone will operate 24 hours a day, seven days a week. All year round.

How much is the Portsmouth CAZ charge?

The charge you need to pay is dependent on your vehicle type. Taxis and private hire vehicles will need to pay a £10 fee. HGVs, buses and coaches will pay a £50 fee. Private cars or motorcycles are exempt from this charge.

Charges apply daily, so if you're entering and exiting the zone multiple times on the same day, you will only need to pay once.

But, if you drive in the zone across two days, for example before midnight and after midnight, you'll need to pay two daily charges.

Fines for the Portsmouth CAZ

If you forget to pay the fee, you’ll get a Penalty Charge Notice (PCN) in the post for a £120 fine. This is reduced to £60 if you pay it within 14 days.

The Penalty Charge is payable in addition to the Clean Air Zone daily charge dependant on your vehicle type.
