The Security Industry Authority (SIA) introduced the Approved Contractor Scheme (ACS) to raise performance standards within the security industry. The ACS is the quality benchmark within security, and sets out criteria that companies must adhere to in order to be SIA ACS Approved.

SIA ACS approval is not only a source of confidence for buyers of security services as they seek to select a trusted provider, it also provides an excellent framework for setting, improving and monitoring your own standards. SIA ACS approval is voluntary and instantly positions your company as having been independently assessed and meeting a recognised level of performance.

Being approved to SIA ACS demonstrates your company is committed to customer service and compulsory licensing of your staff. Your customers can rest assured your private security operatives deliver a quality service in any of the following areas in which you choose to be assessed:

How would a SIA ACS Accreditation benefit my Organisation?

  • Provides a competitive edge over others in the market and gives confidence in the service you will provide.
  • Inclusion in the Register of Approved Contractors published on the SIA website.
  • Authority to use the ACS Accreditation Mark on stationery, livery and websites.
  • Approval may provide access to tender processes where ACS is a pre-requisite.
  • Displaying the standard assures your customers, partners and employees of your position as an exemplary private security service provider.
