Quality Assurance

ISC has embedded quality into the core of its business and operations. Committing to excellence and continual improvement in everyday activities and strategic planning. Our Quality Certifications, as displayed below, have been held for many years. We are externally assessed every 6 months, supported by a robust internal assessment program.

SIA (Security Industry Authority)

The SIA is responsible for regulating the private security industry in the UK.


ACS (Approved Contractor Scheme)

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.
