Clean Air Zone exemptions

Drivers and operators of non-compliant buses, coaches, heavy goods vehicles, taxi and private hire vehicles are required to pay a daily charge to enter the CAZ unless their vehicle has been granted an exemption.

Exemptions for some vehicles have been set nationally, and others are only applicable to the Portsmouth CAZ. In Portsmouth some vehicles are also being offered a time-limited ‘sunset period’ which will give drivers and operators a short time to replace or retrofit their vehicle once the CAZ is launched.

If you operate a non-compliant vehicle that would normally be charged to drive in the CAZ, applying for an exemption or sunset period will allow you to avoid a charge. Your exemption will only be valid once you’ve received confirmation from Portsmouth City Council.

You’ll need to apply for an exemption or sunset period through an online form. You’ll also need to supply evidence to prove you’re eligible, which is outlined below.

You can check your registration on the government’s CAZ checker. Vehicles which are nationally exempt or non-chargeable don’t need to apply for a local exemption. However, if your vehicle is appearing with a charge for travel through the Portsmouth CAZ, you may be eligible for a local exemption.

Some vehicle types, such as Non-Commercial Vintage Buses and Horse Transporters, are exempt for up to ten days per year. If you intend to apply for this exemption, you should still apply now, even if you don’t know the exact dates you’ll be travelling. You can tell us later when you’ll be entering the CAZ.

If you’re not sure what Euro standard your vehicle is, please check your vehicle log book.

The zone is approximately 3km2, and is located to the south west of Portsmouth.
