The Ultra Low Emission Zone (ULEZ) is a British government initiative to clean up the air in the City of London, due to the high levels of pollution and the health consequences it was causing.  

It began in April 2019, with London Mayor Sadiq Khan setting the world's strictest standard for air quality preservation. 

It is estimated that "air pollution costs the capital up to £3.7 billion a year, and £20 billion a year for the country as a whole. The Ultra Low Emission Zone (ULEZ) will help tackle the health crisis caused by toxic air in London, which currently causes thousands of premature deaths each year and increases the risk of asthma, cancer and dementia," according to the press release issued by the city's mayor. 

How does it work? 

Vehicles that do not comply with emissions regulations and are not exempt will be required to pay a daily charge of £12.50

Vehicles to which the regulations apply: 

  • Cars 
  • Motorcycles 
  • Vans 
  • Special vehicles up to 3.5 tonnes 
  • Minibuses up to 5 tonnes 
💡
The ULEZ zone is active 24 hours a day, 7 days a week, with the only day free to drive without restriction being 25 December each year. 

How to pay Ultra Low Emission Zone 

Many drivers have chosen to purchase vehicles that comply with the regulations, but if your vehicle does not comply, there are several ways to pay: 

  • Payment in advance 
  • Pay within 3 days of your journey (before midnight) 
  • Automatically, subject to prior configuration 

You can pay online or via the Android and Apple mobile apps. 

Another payment method is by telephone using the following numbers: 

  • National: 0343 222 2222 (charges may apply) 
  • International: +44 343 222 2222 
  • Text message: 020 7649 9123 (for hearing impaired) 

Where is the ULEZ zone in London? 

It covers the City of London and 32 boroughs, with the M25 orbital motorway as the boundary, but not including it.

If you are travelling near the boundaries and are unsure whether you have to pay the ULEZ charge, you can check by entering your postcode before starting your journey.  

This way, you can plan ahead and avoid paying the charge if possible. 

What cars are ULEZ compliant? 

Vehicles that comply with the relevant Euro standard will be exempt from paying the ULEZ charge and will therefore be able to circulate freely: 

  • Euro 3: for motorcycles, mopeds, tricycles and quadricycles (category L)  
  • Euro 4: (NOx) for petrol cars, vans, minibuses and other special vehicles 
  • Euro 6: (NOx and PM) for diesel cars, vans, minibuses and other special vehicles 

You can check whether your vehicle complies with the regulations in its documentation and on the official Transport for London website.  

How to apply for ULEZ exemptions 

Applications must be made online, attaching the documents supporting the application in the appropriate section. 

You may be eligible for a refund, discount or exemption from payment in the following cases: 

  • People with disabilities 
  • Private or rental wheelchair-accessible vehicles 
  • People who already receive disability benefits 
  • People who are responsible for people with disabilities 
  • Suffering from a terminal illness or severe blindness 
  • NHS (National Health Service) patients 
  • Taxis 
  • Community transport minibuses 
  • Historic vehicles with exemptions 
  • Other special vehicles (military, agricultural, excavators, cranes, etc.) 
  • Some vehicles used for travelling shows 

Difference between LEZ and ULEZ 

The ULEZ and LEZ (Low Emission Zone) cover exactly the same area. The difference lies in the vehicles assessed. 

While the former covers all vehicles under 3.5 tonnes or up to 5 tonnes for minibuses, the Low Emission Zone (LEZ) includes all vehicles over 3.5 tonnes, and buses, minibuses and coaches over 5 tonnes

These vehicles will be subject to the charge if they do not comply with Euro 6 emissions standards.  

If they do comply, they will be exempt, as in the case of ULEZ. 

Difference between ULEZ and Congestion Charge 

While ULEZ applies a pollution charge, the Congestion Charge zone applies a charge in areas where traffic is most concentrated, thus discouraging drivers from entering these areas during rush hour.  

This tax is applied during peak hours: 

  • Monday – Friday: 07:00-18:00 
  • Saturdays, Sundays and Bank Holidays: 12:00-18:00 
  • It will not apply on Christmas Day (25 December) or New Year's Day (1 January).
