Royal warrant of appointment in the context of "Royal Charter"

A royal charter is a formal grant issued by a monarch under royal prerogative as letters patent. Historically, they have been used to promulgate public laws, the most famous example being the English Magna Carta (great charter) of 1215, but since the 14th century have only been used in place of private acts to grant a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as boroughs (with municipal charters), universities and learned societies, and were historically used to establish companies.

Charters should be distinguished from royal warrants of appointment, grants of arms, and other forms of letters patent, such as those granting an organisation the right to use the word "royal" in their name or granting city status, which do not have legislative effect. The British monarchy has issued over 1,000 royal charters. Of these about 750 remain in effect.

Royal Worcester is a porcelain brand based in Worcester, England. It was established in 1751 and is believed to be the oldest or second oldest remaining English porcelain brand still in existence today, although this is disputed by Royal Crown Derby, which claims 1750 as its year of establishment. Part of the Portmeirion Group since 2009, Royal Worcester remains in the luxury tableware and giftware market, although production in Worcester itself has ended.

The Worcester Royal Porcelain Co. Ltd. (known as Royal Worcester) was formed in 1862, and although the company had a royal warrant of appointment from 1788, wares produced before that time, as well as those produced at two other factories in Worcester, are known as Worcester porcelain. The enterprise has followed the pattern of other leading English porcelain brands, with increasing success during the 18th and 19th centuries, then a gradual decline during the 20th century, especially the latter half.

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. 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 have usually been made by the monarch, their spouse, and their 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.
