A ULEV vehicle is classed as a vehicle which has less than 75 grams of CO2 per kilometre (g/km) from its exhaust pipe.
Please note: as and when the Vehicle Certification Agency replace the required (g/km) level, the policy will match the latest national requirements.
If you currently own a licensed saloon hackney vehicle
- You can continue using your non ULEV saloon Hackney until the 31 of March 2021.
- You must replace your saloon vehicle with a ULEV or electric saloon vehicle. This means it must have less than 75 g/km of CO2.
If you currently own a licensed wheelchair accessible taxi
- Licensed non ULEV wheelchair accessible taxis can remain in use until the vehicle reaches 15 years old.
- From the 31 March 2026, all wheelchair accessible taxis are required to become ULEV or electric.
- You will be required to replace your non ULEV wheelchair accessible taxi with a ULEV vehicle (wheelchair accessible or saloon) by 31 March 2026, or when the vehicle reaches 15 years old – whichever date is soonest.
