A livery company is a type of guild or professional association that originated in medieval times in London, England. Livery companies comprise London's ancient and modern trade associations and guilds, almost all of which are styled the "Worshipful Company of" their craft, trade or profession. There are 113 livery companies as of March 2025. They play a significant part in the life of the City of London, not least by providing charitable-giving and networking opportunities. Liverymen retain voting rights for the senior civic offices, such as the Lord Mayor and Sheriffs of the City Corporation, London's ancient municipal authority with extensive local government powers.
The term livery originated in the designed form of dress worn by retainers of a nobleman and then by extension to special dress to denote status of belonging to a trade. Livery companies evolved from London's medieval guilds, becoming corporations by royal charter responsible for training in their trades, as well as for the regulation of aspects such as wage control, labour conditions and industry standards. Early guilds often grew out of parish fraternal organizations, where numerous members of the same trade lived in close proximity often congregating at the same church. Like most organisations during the Middle Ages, these livery companies had close ties with the Roman Catholic Church (before the Protestant Reformation), endowing religious establishments such as chantry chapels and churches, observing religious festivals and hosting ceremonies as well as well-known mystery plays. Most livery companies retain their historical religious associations, although nowadays members are free to follow any faith or none.
