To help improve air quality, an Ultra Low Emission Zone (ULEZ) operates 24 hours a day, 7 days a week, every day of the year,except Christmas Day, within the same area of central London as the Congestion Charge. Most vehicles, including cars and vans, need to meet the ULEZ emissions standards or their drivers must pay a daily charge to drive within the zone:

£12.50 for most vehicle types, including cars, motorcycles and vans (up to and including 3.5 tonnes)

£100 for heavier vehicles, including lorries (over 3.5 tonnes) and buses/coaches (over 5 tonnes)
