SIA Approved Contractor Scheme (ACS) Routes to Approval

CCAS is one of only two certification bodies approved by the Security Indusrty Authority (SIA) to carry out assessments to either the ACS Standard Route or ACS Passport Scheme. 

To date, CCAS has assessed in excess of 250 security firms to the Approved Contractor Scheme across the United Kingdom, since it was first launched in February 2006.

The SIA Approved Contractor Scheme is based upon widely recognised business improvement models: ISO 9001 and the European Foundation for Quality Management (EFQM) Excellence Modelâ„¢. The Scheme also references the British Standard codes of practice applicable to the private security industry and conformance to the relevant codes is built into the ACS requirements.

There are two routes to approval, either the Standard Route or the CCAS Passport Scheme, each designed to meet the same challenging requirements.

CCAS two routes to approval are as follows:

      ACS Standard Route          

              CCAS Passport Scheme Approval

Organisations that already hold approval to the SIA ACS Standard Route can transfer their approval to the CCAS Passport Scheme. This is particularly advantageous for companies that hold additional approvals such as ISO 9001:2015, who are looking to reduce their assessment costs - this can be achieved by combined assessments being undertaken through the Passport Scheme.
