Tax rates have changed in 2020 to reflect the improved emission tests. These tests now sit in line with what is known as WLTP - Worldwide Harmonised Light Vehicle Test Procedure - which is based on more realistic conditions than the previous testing standard. The tests now take into account the difference between driving in suburban and urban areas, longer distances, higher average and max speeds, and more realistic driving behaviour.
Due to the more rigorous nature of the test, higher emissions will be recorded. This means that all VED rates will need to be reassessed, and drivers of petrol and diesel cars will have to pay a higher amount.
Tax rates last changed in April 2017, with VED being calculated purely on a vehicle’s carbon dioxide emissions. Only cars with 0g/km CO2 emissions will be exempt from paying. The reason for this change is down to the large amount of CO2 still being emitted from the country’s cars.
