COVID-19 Update: Our Locksmiths Are Open More Info

MLA Membership Categories & Logos

There are 2 main categories of membership of the Master Locksmiths Association where you’ll see the logo being used.

1. MLA Approved Companies

MLA Approved Company Logo
These are locksmith companies who have met the stringent “Vetted, Inspected and Qualified” criteria of the MLA.

By having met the criteria it helps the end user rest assured that they are using a bonafide locksmith, who have met some minimum standards.

Approved Companies can be found on our find a locksmith page.

With the lack of government-backed regulation within the locksmithing industry, we think it’s vital that the public is protected and hence we recommend the use of MLA Approved Companies whenever somebody needs a locksmith.

2. MLA Affiliate Members

MLA Affiliate Member Logo
These are companies who supply the locksmith industry.

They may be a) manufacturers or b) distributors of security products, c) wholesalers to the locksmith industry or even insurance companies.

Some may even have the MLA Affiliate logo on their products or the packaging of their products to highlight their affiliation with the MLA. MLA Approved Company Locksmiths will often purchase their products from MLA Affiliate members.

Other Logos To Look Out For 

In terms of other logos that you may want to watch out for there are the following:

 1. Sold Secure

Sold Secure - the approval for security devices
Sold Secure is one of the leading suppliers of test and certification services for security-related products.

2. Kitemark

Kitemark Logo

The British Standard kitemark is another approval that you may want to look out for on certain security products.

Run by the British Standards Institute it’s a stamp of approval to demonstrate that certain standards have met. For example, the most common BS standard for mortice locks is BS3621.

In fact, many insurance companies stipulate you need a BS3621 lock to comply and the easiest way to check is to get your local MLA licensed locksmith to confirm the locks are indeed Kitemarked to BS3621, and if not to upgrade them.

A number of locksmiths also do alarm work, and in the same way that the MLA runs its accreditation scheme for locksmiths, there are 2 main companies that do the same for Alarm work.

3. NSI

NSI Approved Company Logo
The National Security Inspectorate (NSI) operates a 2 tier approach to approvals. This allows companies to grow and develop their business whilst consistently developing the NSI reassurance to their customers.

Companies can enter at either level:

Silver is designed for ‘Product Certification’ Refers to the ‘Product Certification’ against sector-specific standards, e.g. BS7858, BS8243.
