DVLA have made changes to the legalities of black and silver number plates as of 1st January 2021. In their statement, they’ve said; “The change seeks to prevent any vehicle constructed after 1 January 1980 from the ability to display the black and silver number plate despite being recorded in the DVLA’s historic tax class. Those vehicles with a construction date prior to 1 January 1980 will continue to be able to legally display black and silver number plates to avoid any undue costs of replacement.”
From “1st January it will no longer be permissible to fix a new number plate displaying a Euro symbol. Number plates already fixed to vehicles are unaffected. We will also be introducing a new British Standard for number plates produced from 1 September 2021 which will mean all current style number plates that are first fixed to a vehicle from that date must meet the technical requirements contained in that standard.”
