Key Summary
ULEZ was introduced in 2019. The aim was to charge people if they used a car deemed as polluting in London. Charges vary, with the main aim being to deter people from polluting cars.
Any car registered after 2006 must meet certain standards to be ULEZ compliant. For petrol cars, this is Euro 4 emission, and for diesel this is Euro 6 emission standards.

As we continue to face the impacts of global warming, more and more measures have been taken to reduce emissions. Clean air zones have appeared across the UK, and London is no exception. The introduction of the ultra-low emission zone (ULEZ) in 2019 has left many wondering whether they’ll have to pay to drive around London. Fear not, Marsh Finance has provided everything you need to know about ULEZ, including whether your car is exempt from any charges.

ULEZ Explained
To understand ULEZ it is important to go back to 2017. At this point, London has been declared a very high pollution threat for the first time. The air was polluted by emissions and the mayor at the time, Sadiq Khan, felt it necessary to intro duce the Toxicity Charge (T-Charge). This charge was £10 per day and was applied to anyone who entered a certain zone. As a result of the charge, emissions dropped by 20% and high-polluting cars entering London fell from around 36,000 to 26,000. This significant fall showed the success of such a policy and started the journey towards ULEZ. In 2019, ULEZ was launched. This charge covered the same area as the T-Charge but was in effect 24/7, all year round. The charges you will face under ULEZ are as follows;
- £12.50 a day for cars, vans and motorcycles
- £100 a day for buses, coaches and lorries
The ULEZ charge attempts to deter people from driving in the area and with that reduce emissions.
The zone covers central London and the surrounding Greater London area. Anyone who enters the area, whether they live there or not, will be subject to the charge. If you’re driving to London any time soon, you may be wondering what your charge will be. Fortunately, not all vehicles are liable to this charge, and so you may be wondering if you are ULEZ compliant. With that, we have covered what makes a vehicle exempt from ULEZ charges.

To better help you understand how ULEZ is set up around London, Transport for London have produced a handy map 👇.

What Makes A Car ULEZ-Compliant?
Any car registered after January 2006 must meet certain standards to be ULEZ compliant. For petrol cars, they must meet the Euro 4 emission standards. These standards are as follows:
- Petrol cars have to produce CO of no more than 1.0g/km,
- Total Hydro Carbon (THC) emissions of no more than 0.10g/km
- NOx emissions of 0.08g/km.
If your petrol car meets Euro 4 standards, you won’t have to pay to enter a ULEZ zone.
For diesel cars, they must meet Euro 6 standards to avoid ULEZ charges. Euro 6 standards state the following:
A diesel car cannot emit more than 80mg/km of NOx gases.
Again, any diesel car that meets this standard will be able to miss out on ULEZ charges.

How Can I Check If My Car Is ULEZ-Compliant?

What Is ULEZ? - FAQS
What is ULEZ?
ULEZ stands for Ultra Low Emission Zone, and is an area covering the inner city of London and its outskirts. Cars that are not ULEZ complaint and enter the zone will have to pay a fee: £12.50 a day (cars, vans, motorcycles) and £100 a day (buses, coaches and lorries).
The aim of ULEZ is to push people to making their cars ULEZ compliant, whilst reducing trips in and out of the zone, whether that be walking or alternate transport.
Where is the ULEZ zone?
The ULEZ is focused on London, going from the capital to neighbouring areas like Buckinghamshire, Hertfordshire, Essex, Kent, and Surrey.
Any non-compliant ULEZ cars that travel through this area will have to pay the charge, depending on their type of vehicle.
How much is ULEZ charge/fine?
The fine depends on what transport you are in:
- £12.50 a day for cars, motorcycles and vans.
- £100 a day for buses, coaches and lorries.
Is my car ULEZ compliant?
If you have a petrol car, it must meet Euro 4 Emission standards to be ULEZ-compliant.
If you own a diesel car, it must meet Euro 6 Emission standards.
Electric vehicles (EVs) are ULEZ-compliant.
You can check if your car is ULEZ-compliant via a free online tool: https://motorway.co.uk/ulez-checker.
How to pay ULEZ
You have two options when it comes to ULEZ payments. You can either:

Why do we have ULEZ?
