TSG and sister brand Definitive Security have won Approved Contractor Scheme (ACS) accreditation, the set of standards overseen by the Security Industry Authority (SIA).

Independently monitored, the ACS endorsement process examines how well an organisation is managed, how effectively it services its customers and how well it treats its employees.

Companies are judged across nine categories including Strategy, Commercial Relationship Management, Resources, People and Leadership.

TSG achieved ISO 9001 for a second successive year in December, but ACS, recognised by clients/potential clients and the police, is another marker for the agency.

A spokesperson for the SIA said: “Approved contractors are committed to customer service and the compulsory licensing of their staff. This means their customers can rest assured that every private security operative deployed on their premises will be working within the law.”

TSG managing director David Boswell, added: “It is a great feeling to achieve Approved Contractor status. It allows us to engage prospects, which might otherwise have been unable to consider deploying our resources. Now, any organisation that wants to can bring our solutions into their security and safety plans.”

Built on a platform of relevant industry codes of practice, the SIA’s Approved Contractor Scheme is a universally recognised mark of quality for private security suppliers, designed to raise performance standards and to assist in developing new opportunities.

Developed in consultation with representatives from across the industry, ACS specifically covers the elements regulated by the SIA and the Private Security Industry Act 2001.
