THE FIVE UK DRIVING ZONES MOTORISTS CONFUSE AND THE FINES THAT CATCH THEM OUT

ULEZ, LEZ, CAZ, ZEZ and the Congestion Charge may sound similar, but they cover different vehicles, operate at different times and carry substantially different charges and penalties.

The differences are particularly important for motorists travelling between cities, as a vehicle that can enter one area for free could be charged or prohibited from entering another.

One of the biggest mistakes drivers make is assuming that all clean air zones work in roughly the same way. They see a sign containing the words 'low emission' or 'clean air' and assume there will be a standard national charge. In reality, the amount you pay, the vehicles covered and what happens when you fail to pay can change completely from one city to another.

1. Ultra Low Emission Zone: £12.50 a day, with a £180 penalty

London's Ultra Low Emission Zone, commonly known as ULEZ, covers all London boroughs and operates 24 hours a day, every day of the year except Christmas Day.



Drivers of cars, smaller vans, minibuses and motorcycles that do not meet the required emissions standards must pay £12.50 for each day they drive within the zone.



Failing to pay the charge can result in a £180 Penalty Charge Notice, reduced to £90 when paid within 14 days. The ULEZ charge is separate from the Congestion Charge and any applicable tunnel charges.



2. Congestion Charge: £18 a day, or £21 when paid late

The London Congestion Charge is designed to manage traffic rather than vehicle emissions and applies within a smaller area of central London during its operating hours.



Since 2 January 2026, the standard daily charge has been £18 when paid in advance or on the day of travel. Drivers paying by midnight on the third charging day after travelling pay £21.
