The SIA’s quality assurance scheme for the private security industry.

To achieve certification under the SIA’s Approved Contractor Scheme (ACS), each applicant needs to meet the requirements of the seven main headings beginning with “Criterion 1 – Strategy” through to “Criterion 7 – Leadership”. All of the criteria consist of key indicators of good practice, which can be found here, alongside the ACS audit process.
