Clean Air Zones (CAZ) are being implemented across many cities in the UK to tackle air pollution and improve public health. While these zones are designed to reduce harmful emissions, they come with costs that directly affect drivers. Understanding the cost of Clean Air Zones is essential to avoid unexpected charges and make informed decisions about driving in these areas.

What Are Clean Air Zones?

Clean Air Zones are specific areas in cities where measures are taken to reduce air pollution. Depending on the type of vehicle and its emissions level, you may be required to pay a fee to drive through these zones.

There are four types of Clean Air Zones:

1. Class A: Includes buses, coaches, taxis, and private hire vehicles.
2. Class B: Includes Class A vehicles plus HGVs (Heavy Goods Vehicles).
3. Class C: Includes Class A and B vehicles plus vans and minibuses.
4. Class D: Includes all vehicle types, including private cars.

Cities such as Birmingham, Bath, and Manchester already have Clean Air Zones in place, and more cities are expected to follow suit.

How Much Do Clean Air Zones Cost?

The cost of Clean Air Zones varies depending on the city and the type of vehicle you drive. For example:

• In Birmingham’s Class D zone, non-compliant vehicles are charged £8 per day for cars and £50 per day for HGVs and buses.
• Bath’s Class C zone charges £9 per day for vans and minibuses and £100 for larger vehicles, though private cars are exempt.

These charges can add up quickly, especially for regular commuters or businesses that rely on vehicles for daily operations.

Are You Affected?

Whether you’ll need to pay depends on your vehicle's emissions rating. Generally, the following vehicles are exempt from charges:

• Euro 6 diesel vehicles (registered after September 2015).
• Euro 4 petrol vehicles (registered after 2005).
• Fully electric or hydrogen-powered vehicles.

It’s important to check your vehicle’s compliance status before entering a Clean Air Zone. Tools like Rooster can help by providing insights into whether your car meets the required standards.

How to Avoid or Reduce CAZ Costs

1. Drive a Compliant Vehicle
   If you’re frequently driving in Clean Air Zones, consider upgrading to a compliant vehicle. While this requires an upfront investment, it can save you significant money over time by avoiding daily charges.
2. Plan Your Routes
   Use navigation apps or tools like Rooster to plan routes that avoid Clean Air Zones whenever possible. This is especially helpful if you’re only passing through a city and don’t need to enter the central areas.
3. Consider Public Transport or Park-and-Ride
   If driving through a Clean Air Zone is unavoidable, consider leaving your car in a park-and-ride facility and completing your journey via public transport. This can significantly reduce your costs and environmental impact.
4. Use Rooster’s Tools
   Rooster provides tools to help you navigate the cost of Clean Air Zones, including alerts for CAZ boundaries and insights into vehicle compliance. By staying informed, you can avoid unexpected charges and make smarter decisions about when and where to drive.

The Bigger Picture

Clean Air Zones are a key part of the UK’s effort to combat climate change and improve air quality. While they come with costs, they also encourage drivers to adopt greener habits, such as carpooling, using public transport, or transitioning to electric vehicles.

By understanding the cost of Clean Air Zones and using resources like Rooster, you can minimise your expenses while contributing to a cleaner environment.
