The Private Security Industry Act 2001 requires the SIA to establish a "system of inspection for providers of security services, under which those organisations who satisfactorily meet the agreed standards may be registered as approved, and may advertise themselves as such".
The objective of the SIA's Approved Contractor Scheme is to raise performance standards and to assist the private security industry in developing new opportunities. The scheme is voluntary and was developed in consultation with representatives from across the industry; it only covers those parts of the industry that are regulated by the SIA and the Private Security Industry Act 2001 (as amended). There is a single scheme, with sector-specific approval based on a relevant set of qualifying criteria.

It is an offence for a company to claim it is an approved contractor when it is not; this includes indirectly claiming to be an approved contractor by displaying the ACS accreditation mark. The penalty is a fine of up to £5,000.
