Until the Security Industry Authority brings locksmiths under the Regulation of the Private Security Industry Act, the MLA licences its Approved Company to use its highly esteemed logo. To gain this licence, applicant locksmithing companies undergo the MLA’s inspection procedures.

By having its own inspectorate the MLA demonstrates that its high standards are being met by all Approved Companies and, to ensure maintenance of these standards, every company is inspected on a regular basis. The main subject of an inspection is the workmanship of its members and their operatives. It is also important to the Association that all members conform to legal requirements and that systems exist to service customer satisfaction.

The Master Locksmiths Association now has a comprehensive national network of Approved Companies and the Association's Head Office directs enquirers to their nearest licensed locksmith company on a daily basis.

The logo depicted right is the one that is advertised by an approved company on their premises, vehicles and stationery, confirming to the public the standards expected of them.

The MLA operates schemes whereby discounts may be available to policy-holders of most well known insurance companies and they provide the service behind many major help-lines.
