“Royal warrants of appointment have been issued for centuries to those who supply goods or services to a royal court or certain royal personages. The warrant enables the supplier to advertise the fact that they supply to the royal family, so lending prestige to the supplier. In the United Kingdom, grants are currently made by the three most senior members of the British Royal Family to companies or tradesmen who supply goods and services to individuals in the family. Suppliers continue to charge for their goods and services – a warrant does not imply that they provide goods and services free of charge. The warrant is typically advertised on company hoardings, letter-heads and products by displaying the coat of arms or the heraldic badge of the royal personage as appropriate. Underneath the coat of arms will usually appear the phrase “By Appointment to...” followed by the title and name of the royal customer, and then what goods are provided. No other details of what is supplied may be given. The earliest recorded British royal charter was granted to the Weavers’ Company in 1155 by Henry II of England. Food and drinks suppliers have always been some of the most important warrant holders to the palace. One of the first monarchs to grant a warrant was King George IV, who turned Buckingham Palace into his residence”. – Wikipedia

The warrant holders can display the certificate and use the royal coat of arms in their marketing. The warrants lasting five years can help businesses break into new markets overseas, using their role as supplier to the royal family as a gauge of quality. On September 9, Queen Elizabeth will overtake Queen Victoria as Britain's longest-serving monarch. (Photo by Toby Melville/Reuters)
