The Ultra Low Emission Zone (ULEZ) replaced the T-Charge on 8 April 2019. It operates 24 hours a day, 7 days a week, every day of the year (except Christmas Day), within the same area as the Congestion Charge zone. 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. As of January 2020, the fees are: £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).
