The organisation was originally a trade association for makers of metal parts for bridles, harnesses, spurs and other horse apparel; hence the company's name, which comes from the Latin word lorum through the French word lormier.

The Loriners' Company is permitted (by the Court of Aldermen) a Livery complement of up to 500 and currently comprises over 400 members (including assistants, liverymen, freemen and apprentices).

Whilst no longer authorised to regulate lorinery business throughout the London area, the company still administers examinations for students of its trade within the United Kingdom.

[1] The Loriners' coat of arms is Azure on a Chevron Argent, between three Manage-bits Or, as many Bosses Sable, supported asymmetrically by a single Horse, between Foliage of Palm and of Juniper.

Many other well known equestrians belong to its number including Captain Mark Phillips CVO and Samuel Vestey (Master of the Horse).
