Ultimate ULEZ Guide: Everything UK Drivers Need to Know

Ultimate ULEZ Guide: If you drive in or around major UK cities, you’ve probably heard about ULEZ — but understanding how it works (and whether your car is affected) isn’t always straightforward. Ultra Low Emission Zones are designed to reduce air pollution by charging higher-emission vehicles a daily fee for entering certain areas.

Whether you commute into a city, visit occasionally, or live inside a zone, knowing the rules can save you money and avoid unexpected charges.

What is ULEZ?

ULEZ stands for Ultra Low Emission Zone. It’s a charging scheme that applies to vehicles which don’t meet specific emissions standards. If your car doesn’t comply and you enter a ULEZ area, you’ll need to pay a daily charge.

The scheme was first introduced in London by Transport for London, but similar Clean Air Zones now exist in several UK cities.

The goal is simple: encourage cleaner vehicles and improve air quality in busy urban areas.

Which vehicles are affected?

ULEZ rules apply to most vehicle types, including cars, vans, motorcycles, and lorries. For cars, compliance is based on emissions standards rather than age alone.

Generally speaking:

• Petrol cars must meet Euro 4 standards (usually registered from 2006 onwards)
• Diesel cars must meet Euro 6 standards (typically registered from late 2015 onwards)

However, registration date isn’t a guarantee — some older cars already meet the standards, while some newer imports may not.

That’s why checking your exact vehicle is essential.

How much is the ULEZ charge?

If your vehicle doesn’t meet the emissions requirements, you’ll usually pay £12.50 per day for cars and motorcycles. Larger vehicles such as vans and lorries face higher charges.

Importantly, this is a daily fee — not per journey. Whether you drive five minutes or five hours within the zone, the charge is the same for that day.

Failing to pay on time can result in penalty charges.

Where does ULEZ apply?

London currently has the largest ULEZ, covering all boroughs. Other UK cities operate Clean Air Zones with their own rules and pricing structures.

Each city sets its own boundaries and enforcement methods, so it’s important to check before travelling. Some zones run 24/7, while others only operate during certain hours.

Vehicle compliance data is linked to your registration through the Driver and Vehicle Licensing Agency, which authorities use to determine whether charges apply.

How to check if your car is ULEZ compliant

The easiest way is through the Rooster app.

By clicking through to the CAZ Check, you can effortlessly view which cities your car is compliant with and which ones may require a daily charge, along with the exact amount you’ll need to pay.

Rooster also provides direct links to pay charges where required, helping you avoid fines and last-minute stress.

What happens if you don’t pay?

If you enter a ULEZ area in a non-compliant vehicle and don’t pay by the deadline, you’ll receive a Penalty Charge Notice (PCN). These fines can be significantly higher than the original daily charge.

Cameras automatically capture number plates, so there’s no manual checking — enforcement is fully automated.

Are there any exemptions or discounts?

Some vehicles are exempt, including:

• Certain historic vehicles
• Disabled passenger vehicles (with qualifying tax class)
• Emergency vehicles

Residents previously received temporary discounts in some areas, but many of these schemes have now ended.

If you think your vehicle may qualify for an exemption, always confirm before travelling.

Is it worth upgrading your car to avoid ULEZ?

That depends on how often you drive in affected areas.

If you only enter occasionally, paying the daily charge may be cheaper than changing vehicles. But if you commute regularly, upgrading to a compliant car — or switching to electric — can quickly become more cost-effective.

ULEZ has also impacted used car prices, with compliant vehicles generally holding their value better in urban areas.
