Under the provisions of the Gun Barrel Proof Act, all guns sold in the United Kingdom must undergo proof to test the basic soundness of barrel and action. Together with Birmingham, the London Proof House provides proofing and other services to the British gun trade. The Proof Master may also be requested to investigate accidental gun and barrel failures.

Since 1675, the Worshipful Company of Gunmakers has been located at its present location, just outside Aldgate and the old walls of the City of London. For directions visit our Contact page.


The Company operates the Proof House, which has statutory powers to test and regulate the safety of firearms.


Members of the Livery serve as trustees of the Gunmakers Company Charitable Trust, which provides assistance for training gunmakers and advancement of the art and technology of gunmaking and related trades.


The Company organises formal dinners and other activities and events for its liverymen (which includes women).


The Livery participates in the governance of the City of London, including the election of the Sheriffs and the Lord Mayor.


No gun can be legally sold in the United Kingdom without having undergone proof.


The Proof House is called in to investigate accidents caused by firearms malfunction.


The Proof House ensures and certifies that guns wanted for display purposes, rather than use, have been made permanently unusable in the manner required by law.
