This isn't the first time the zone has expanded. Originally launched in 2019 and covering the same area as the central London congestion charge zone, the ULEZ was first enlarged in October 2021 to cover all areas within the North and South Circular ring roads.
This latest expansion is the largest yet, however, bringing all London authorities within the M25 into the clean air zone.
Unlike the congestion charge zone, which remains unchanged, the ULEZ operates 24 hours a day, 364 days a year (the exception being Christmas Day).
Read on to find out exactly where the zone applies and to ensure you're not caught out by the new changes.

The Ultra Low Emissions Zone was introduced to tackle air pollution and lower vehicle emissions – particularly harmful NOx and particulate matter - within London. It has also become a template for similar clean-air zones in Bristol and Birmingham.
Automatic numberplate recognition cameras can identify cars driving both in and out of the zone (as well as within it), with a daily £12.50 charge applied to vehicles that don't meet the required ‘Euro’ emissions standard for their fuel type.
Currently, petrol cars have to meet the Euro 4 official standard, which was introduced in 2005.
Diesel cars are penalised more heavily due to their greater particulate matter emissions and must meet the much newer Euro 6 standard (2014 onwards), which saw many diesel vehicles fitted with additional exhaust-cleansing technologies.
Drivers who fail to pay the ULEZ fee are liable for a £180 penalty charge, reduced to £90 if paid within 14 days.

The London Mayor’s office claims that around 84% of cars registered within the Greater London area already meet the required emissions standard and won’t be charged.
