The rules apply to any new number plate fixed to a vehicle from 1 September 2021. This includes both those fixed to new vehicles and any replacement number plates. Number plates already fixed to vehicles before 1 September 2021 do not need to be replaced but must still fully comply with the legal standards, including complying with the British Standard that applied when the number plates were fixed to the vehicle.
