Royal warrants of appointment have been issued since the 15th century to those who supply goods or services to a royal court or certain royal personages.[1] The warrant enables the supplier to advertise the fact that they supply to the royal family, thereby lending prestige to the brand or supplier. In the United Kingdom, grants are usually made by the monarch, spouse, and heir apparent to companies or tradespeople who supply goods and services to individuals in the family.
Suppliers continue to charge for their goods and services – a royal warrant of appointment does not imply that they provide goods and services free of charge. The warrant is typically advertised on billboards or company hoardings in British English, 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.
