Livery Company

The livery companies of the City of London, currently 110 in number, comprise London's ancient and modern trade associations and guilds, almost all of which are styled the "Worshipful Company of..." their respective craft, trade or profession. London's livery companies play a significant part in City life, not least by providing charitable-giving and networking opportunities. Liverymen retain voting rights for the senior civic offices, such as the Lord Mayor, Sheriffs and City of London Corporation, its ancient municipal authority with extensive local government powers.

The term livery originated in the specific form of dress worn to 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 under Royal Charter responsible for training in their respective trades, as well as for the regulation of aspects such as wage control, labour conditions and industry standards. Like most organisations during the Middle Ages, these livery companies forged close ties with the Church of Rome (at least prior to the Protestant Reformation) by endowing religious establishments such as chantry chapels and churches, by observing religious festivals with hosting ceremonies and their well-known mystery plays. Most livery companies retain their historical religious associations, although nowadays members are free to follow any faith or none.

Most livery companies still maintain contacts with their original trade, craft or professional roles. Some still exercise powers of regulation, inspection and enforcement, while others are awarding bodies for professional qualifications. The Scriveners' Company admits senior members of legal and associated professions, the Apothecaries' Company awards post-graduate qualifications in some medical specialties, and the Hackney Carriage Drivers' Company comprises licensed taxi drivers who have passed the "Knowledge of London" test. Several companies restrict membership only to those holding relevant professional qualifications, eg. the City of London Solicitors' Company and the Worshipful Company of Engineers. Other companies, whose trade died out long ago, such as the Longbow Makers' Company, have evolved into being primarily charitable foundations.
