Portsmouth 2026: Clean Air Zone Spares Cars at the Dockyard
Portsmouth, United Kingdom · CAZ
Portsmouth's Clean Air Zone charges higher-polluting buses, coaches, taxis, vans and lorries — but NOT private cars, which can drive in free. So for most visitors the considerations are parking on this densely built island city, and driving on the left. Portsmouth, Britain's great naval port, is home to the Historic Dockyard with HMS Victory and the Mary Rose, the Spinnaker Tower and the seafront. Park in a garage and walk; a ferry serves the Isle of Wight.

Frequently Asked Questions
No. Portsmouth operates a class B Clean Air Zone that charges higher-emission buses, coaches, taxis, private hire vehicles and heavy goods vehicles, but private cars and vans are not charged. So you can drive a car into Portsmouth without a CAZ fee. The practical considerations are parking in this compactly built island city and driving on the left, rather than the zone itself.
On the left, as throughout the UK. For overseas visitors that's the main adjustment, along with roundabouts taken clockwise. Rental cars are right-hand drive. Portsmouth is built on Portsea Island and is densely developed, so parking can be tight near the main attractions; many visitors park in a central or dockyard car park and walk or use local transport.
Use a multi-storey car park near the Historic Dockyard, Gunwharf Quays or the seafront, depending on what you're visiting. The main attractions are walkable from these. There are also park-and-ride options. Portsmouth is compact, so parking once near your destination and exploring on foot is the easy approach, with the CAZ not affecting private cars anyway.
Portsmouth is Britain's premier naval heritage city, home to Portsmouth Historic Dockyard with Nelson's flagship HMS Victory, the Tudor warship Mary Rose and her museum, and HMS Warrior, plus the Royal Navy museum. Add the Spinnaker Tower with its views over the harbour, the Gunwharf Quays shopping and dining, the seafront and the old town of Old Portsmouth, and Charles Dickens's birthplace. It's also the ferry port for the Isle of Wight and the Continent.
Not for the city — the compact island city and its attractions are walkable, with local buses and trains. A car helps for exploring the surrounding region — the South Downs, the historic towns of Hampshire, the New Forest, and the coast — driven from a central garage, and Portsmouth is a ferry port for the Isle of Wight and France/Spain. Remember to drive on the left, and that the CAZ doesn't affect private cars.
