SIA Approved Contractor Scheme – SIA ACS

We have a team of consultants and auditors nationwide with a wealth of business experience.


Offer quality product with focus on adding value, not just consuming management time


Focus on making certification straightforward and relevant to your business.


Gap Analysis

Consultant will visit your Organisation to review and document your current processes and procedures, highlighting any areas that do not meet the requirements of the Standard.


Now it's time to make sure any required process or procedural changes are made, as highlighted in the Review. QMS can provide templates to assist you in doing this.


An Auditor must now visit to check that the documented processes are being followed and agreed.

Once they are satisfied, you will be awarded your certification.

The SIA ACS (Security Industry Authority Approved Contractor Scheme) 

The SIA ACS (Security Industry Authority Approved Contractor Scheme) is the only recognised scheme to standardise organisations operating within the private security sector.

The standard was designed by members of the security industry in consultation with the Private Security Industry Act 2001. The SIA ACS includes elements of widely recognised business improvement models including ISO 9001 and the European Foundation for Quality Management Excellence Model. The scheme therefore, proves not only your competency in security practices but also demonstrates your continuing investment in improving your operational efficiency.


Your potential clients are increasingly making SIA ACS approval mandatory for their security service providers. So, while the scheme is voluntary, achieving SIA Approved Contractor Scheme status strengthens your position in the private security industry and can improve your eligibility.


Being approved to SIA ACS…

Demonstrates that your service has been independently assessed against recognised standards and that security personnel have been properly trained for the role they will perform
Provides a competitive edge over others in the market and gives confidence in the service you will provide
Gives you entry to the SIA Register of Approved Contractors emphasising your status as one of the strongest providers of private security services available in the UK 

Advantages of becoming an SIA approved contractor


Display the approved contractor plaque and/or certificate at your premises
Add the relevant standards to your vehicle markings, social media and web pages
Purchase additional certificate copies for use during acquisition of new clients or for distribution to existing clients
Displaying the standard assures your customers, partners and employees of your position as an exemplary private security service provider

Based upon a combination of recognised quality standards and industry best practice
