Zero and Ultra Low Emission Vehicles (ULEVs)

ULEVs are currently defined as having less than 75 grams of CO2 per kilometre (g/km) from the tail pipe. These are listed at Pure electric vehicles, and other plug in electric vehicles when driving in the electric mode, produce no tailpipe CO2 or pollution, are cheaper to run than conventional vehicles and can attract financial incentives, for example  ULEVs (which meet euro 6 standards and have a 20 mile zero emission capable range) are currently eligible for the 100% cleaner vehicle discount when entering  the London’s Congestion Charging Zone  and there is no charge for access to the Ultra Low Emission Zones for all ULEVs.

Recognising advances in technology from 2021 we expect to define an ULEV as a car or van that emit less than 50g/km CO2.  New cars with CO₂ emissions of less than 50g/km and a zero emission range of at least 70 miles are eligible for a government grant.  The Plug-in Vehicle grant will pay 35% of the purchase price up to a maximum of £3,500 (the Plug in Car Grant ) for eligible vehicles .To see a list of vehicles eligible for a grant click on the following link:  Note that not all low-emission vehicles will get a grant.  Only vehicles that been approved by the government are eligible.  Pure electric vehicles attract a zero first year Vehicle Excise Duty rate (car tax) and for those under £40,000 a zero rate for supplementary years.  Electricity used to recharge a plug-in vehicle at home attracts only a 5% level of VAT, much lower than road fuels (20%).
