Number plate warning labels
Find out about the requirements for displaying warning labels on gaseous fuelled vehicles and electric and hydrogen vehicles.
Gaseous fuelled vehicles (LPG, LNG, and CNG)
All vehicles powered by gaseous fuels, such as liquefied petroleum gas (LPG), liquefied natural gas (LNG), or compressed natural gas (CNG), must be fitted with warning labelling on their number plates.
Manufacturers and owners of hydrogen and electric-powered vehicles, including hybrids, must also display a number plate warning label.
Electric (EV) and hydrogen (H) fuelled vehicles including hybrids
Owners of hydrogen and electric-powered vehicles, including hybrids, built or modified after 1 January 2019 are legally required to display a number plate warning label.
Owners of electric and hydrogen-fuelled vehicles including hybrids built prior to 1 January 2019 are also encouraged to display number plate warning labels.
The warning label must be placed on the number plate as displayed below.
