The Worshipful Company of Gunmakers was incorporated by Royal Charter in 1637 to promote and regulate gunmaking, a role it still fulfils today.
Governed by the Master, Wardens and Court of Assistants. Activities encompass four broad areas of operation: Regulatory, Charitable, Social and Civic.


From their earliest days, Livery Companies looked out for members who couldn’t work, or those who were sick, the elderly and the widows of members. These philanthropic objects have evolved to meet modern needs, but a key component of Livery activity today remains charitable giving. Many Companies have a dedicated charitable trust to which all members are expected to donate.

For the Gunmakers, the Gunmakers’ Company Charitable Trust was formed in 2003. Its principle object is the support of the heritage craft skills associated with traditional gunmaking by the award of bursaries to employers taking on apprentices. Other objective include support to those in the trade in need and the local community in which the community is situated.
