London’s ULEZ: Your Questions Answered 

The Ultra Low Emission Zone (ULEZ) has been in operation in London since April 8, 2019, in order to combat hazardous air pollution and earn cash for the capital’s public transportation network.

The ULEZ is a zone in which drivers of vehicles that do not meet certain emissions criteria must pay £12.50 per day to travel. The ULEZ was expanded to cover all of London’s boroughs on August 29, 2023.

In this post, we’ll go through the most frequently asked questions about the ULEZ, including where it functions, where the money goes, and how to determine whether or not your car is compliant. Let’s get this party started.

When and where is the ULEZ in effect?

ULEZ will be implemented in all London boroughs from August 29, 2023, and will be in effect 24 hours a day, 364 days a year (except Christmas Day).

If you live in Westminster, Wandsworth, Enfield, Croydon, Barking, or Bromley, you must now verify if your vehicle is ULEZ-compliant. Don’t forget that if you don’t pay the penalty within three days of entering the zone, you could face a £180 punishment (or £90 if paid within 14 days).

How much does the ULEZ fee cost?

The ULEZ tax will be £12.50 per 24 hours of travel in the zone beginning in August 2023. Except for Christmas Day (December 25th), the charge is in effect every day.

If you frequently drive into London and the ULEZ in a non-compliant vehicle, consider enabling AutoPay. You can pay online if it is a one-time transaction.

The ULEZ charge can be paid up to 90 days before your journey, or by midnight on the third day after your journey (source: TfL). It’s always a good idea to pay for your trip ahead of time so you don’t forget.

What is the distinction between ULEZ, LEZ, and Congestion Charge?

Simply put, if you’re traveling into London in a passenger car, motorcycle, or van (up to and including 3.5 tonnes), you should check to see if you’ll be required to pay ULEZ and the Congestion Charge – you can do so here. You don’t need to be concerned about the LEZ because it only applies to HGVs and trucks in London.

If you intend to drive into London with an HGV or Truck, you must first determine whether you are required to pay the LEZ. You can do so right here.

Visit Transport for London’s website for further information on which charges you should pay and how much you should pay.

What types of vehicles are ULEZ compliant?

Entering your license plate into Transport for London’s online vehicle checker is the quickest way to see if your car is ULEZ-compliant.

To be compliant, petrol vehicles must meet Euro 4, Euro 5, or Euro 6 emission criteria. The majority of gasoline vehicles registered after January 2006 are compliant.

To be compliant, diesel vehicles must fulfill Euro 6 emission criteria. The vast majority of diesel vehicles manufactured after January 1, 2015 are compliant.

Some drivers and vehicles are exempt from the ULEZ. TfL’s ULEZ exemption and discount guide contains a comprehensive list of which drivers and vehicles are exempt from paying the charge.

If you’re unsure if your vehicle is compliant or not, don’t wait until it’s too late – you might face a £180 fine. Check your registration plate ahead of time with TfL’s online registration plate check service.

How can I tell if I’ve entered the ULEZ?

The ULEZ is prominently marked throughout London, and signs will warn you if you are about to enter the ULEZ. If you use a mapping app on your smartphone to navigate about London, it should alert you when you enter the zone.

To avoid unpleasant surprises or fines, always check ahead of time if your route will take you into ULEZ or Congestion Charge zones. You can do so by visiting Transport for London’s website and using the postcode checker function.

Is ULEZ a scam?

The ULEZ is not a ruse. The initiative is intended to make London’s air cleaner, and it is expected to become obsolete as more people switch to electric and low-emission automobiles.

According to Sadiq Khan, Mayor of London, any ULEZ revenue will be used to strengthen London’s public transportation network through new initiatives such as the proposed Superloop bus routes.

According to the BBC, the ULEZ produced over £224 million in 2022 alone (before to the August 2023 extension). It’s worth noting that a large portion of this cash is returned back into the ULEZ to fund the installation and maintenance of ANPR cameras, signs, marketing, and operating expenditures.

It remains to be seen how the additional cash generated by the ULEZ extension in August 2023 will be reinvested in London’s public transportation network. We will update this post as new information becomes available.

What happens to the money earned by the ULEZ?

According to Transport for London, the ULEZ revenue is reinvested back into the program and London’s public transportation network.

The ULEZ scheme is not free to use. Operating expenditures include anything from ANPR camera installation to marketing and customer service. As a result, the cash earned by drivers who pay the ULEZ charge is initially utilized to keep the program running.

Money earned by the ULEZ after running costs can be utilized to invest in London’s public transportation system.

Is it possible to refuse to pay ULEZ?

Failure to pay the ULEZ charge will result in the issuance of a Penalty Charge Notice (PCN). This would cost £180 (£90 if paid within 14 days). If you do nothing about the PCN for 28 days, it will rise to £270.

If you continue to disregard repeated requests and refuse to pay the PCN, Transport for London may refer you to enforcement agencies (bailiffs) to retrieve payments owed to you.

You have 28 days from the date you receive the PCN to pay it or appeal it. If you want to learn more about PCNs related to ULEZ and how to dispute them, go here:

Which vehicles are affected by the ULEZ?

In general, the ULEZ affects pre-Euro 6 types of diesel (those constructed before roughly 2016) and pre-Euro 4 kinds of petrol (those built before 2006). However, certain petrol vehicles that met Euro 4 criteria were available beginning in 2001.

In the event that a car is compliant but not recognized as such by Transport for London (TfL), the onus is on the owner to show documentation verifying its Euro standard – known as a Certificate of Conformity – in order for the car to be given an individual exemption from the levy.

If you don’t already have a copy, you may usually request one from the manufacturer of your vehicle. You risk being fined if you do not register your vehicle with TfL and enter the zone without paying the daily payment.

Non-Euro 6 diesel vehicles and vans, as well as non-Euro 4 petrols and non-Euro 3 motorcycles, are targeted. Historic automobiles (those manufactured before 1983) are free from the ULEZ if they have been granted historic vehicle tax status.

Vehicles built before January 1, 1973, whether for commercial or noncommercial use, are also excluded.

What are the penalties for entering the ULEZ without paying?

To determine your vehicle’s emissions standard status, utilize the TfL checker tool. Drivers who fail to pay the £12.50 ULEZ penalty will be fined £180, which will be reduced to £90 if paid within 14 days.

The LEZ also applies to Euro VI lorries, buses, and coaches, which are vehicles manufactured before 2013 or 2014. They must pay between £100 and £300 (depending on the vehicle emission status) to enter the zone, with failure to pay resulting in a £1,000 punishment (reduced to £500 if paid within 14 days).

According to the most recent data, nine out of ten cars and eight out of ten vans spotted driving in the zone on an average day are already in compliance with the ULEZ limits.

What will the result of the ULEZ be?

According to TfL’s latest estimates, 100,000 vehicles, 35,000 vans, and 3,000 lorries pay the ULEZ tax every day, but the majority of them are “infrequent” visitors who only enter the zone roughly once a year.

According to TfL, ULEZ is especially advantageous to the young, the elderly, and those with respiratory difficulties, as well as residents of high-pollution areas. TfL data previously indicated that about 70% of vehicles entering the zone were compliant.

According to research from February 2023, dangerous nitrogen dioxide (NO2) levels are 46% lower in central London and 21% lower in inner London than they would have been without the ULEZ scheme. Since 2019, nitrogen oxide (NOx) emissions in London have decreased by 23% (13,500 tonnes) compared to what they would have been without the ULEZ.


We hope this guide has helped to answer some of your pressing ULEZ queries. Whether you like it or not, it appears to be here to stay. The good news is that the vast majority of vehicles entering London on a daily basis are already compliant. There are other exceptions for specific situations.
