Security Industry Authority - Approved Contractor Scheme (SIA-ACS)

The 2001 Private Security Industry Act required the SIA to establish a

"system of inspection for providers of security services, under which those organizations who satisfactorily meet the agreed standards may be registered as approved, and may advertise themselves as such."

What is SIA-ACS?

From 20th March 2006 Licenses or Approved Contractor Certificates were legally required for most security companies and staff. Failure to comply is a criminal offence. Without a License or Approved Contractor Certificate it will be illegal to offer or supply many security services.

The SIA Approved Contractor Scheme is a process intended to offer companies the opportunity to both simplify their licensing and to save money. The ACS process demonstrates that a company is competent, well-managed and able to deliver a quality service. BSI is able to verify that a company has reached the required standard. Full details of the scheme can be obtained from the SIA. 

Once accredited, your company will be able to display the Approved Contractor plaque and certificate in your reception or boardroom.
