The Royal Warrant
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 three members of the British Royal Family to companies or tradespeople who supply goods and services to individuals in the family. Several other royal families allow tradespeople to advertise royal patronage, including the ruling dynasties of the Netherlands, Belgium, Thailand, Denmark, and Sweden.
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.
