In May 2024 HM The King and HM The Queen granted their first Royal Warrants of Appointment of the new reign.
The grants were made to companies drawn from those previously holding a Royal Warrant of Appointment to His Majesty as Prince of Wales, who began granting Warrants in 1980.
Companies were reviewed and 145 were granted a Royal Warrant of Appointment to HM The King. Of these, 
seven companies were also granted a Royal Warrant of Appointment to HM The Queen.
The Made In Britain members below granted the honour of a Royal Warrant this year reflect some of the particular interests of the new King, His Majesty’s longstanding commitment to environmental and social values for example, and his love for Scotland and the great outdoors. These manufacturers produce goods in British factories and meet the quality criteria to also display the Made in Britain trademark. They are:
