If your vehicle doesn’t meet the relevant emissions standards, you have to pay the following charge:
£8 per day for cars, taxis and LGVs (Light Goods Vehicles)
£50 per day for coaches, buses and HGVs
You must pay to drive through the Clean Air Zone either:
Up to 6 days before the day of your visit
On the day of your visit
Up to 6 days after the day of your visit
You won’t be notified if you have driven through the Clean Air Zone. As a driver, it is your responsibility to know whether your car meets the emissions standard and then to pay the right charge if necessary. If you fail to pay the charge within the 13 day allocated window, you will be subject to a £120 Penalty Charge Notice (PCN). You can reduce this to £60 if you pay it within 14 days.
You can pay the charge online. If you pay to drive through the CAZ in advance but decide not to enter on that day, you can also apply for a refund.
