Understanding the SIA ACS Accreditation Process and Safety Standards


The SIA Approved Contractor Scheme (ACS) is a benchmark for excellence in the UK private security industry. As a voluntary accreditation, the ACS aims to enhance overall performance standards and professionalism among security companies. This scheme rigorously assesses these companies against a set of criteria, ensuring they meet specific standards of quality and competence.

Obtaining ACS Accreditation:

To obtain ACS certification, a security company needs to undergo a thorough evaluation of its operations, management systems, and performance based on specific criteria. The criteria include many aspects of the company’s activities, such as quality management, staff training, screening procedures, customer care, and compliance with laws and regulations.

Assessment Process of ACS:

The ACS assessment process is systematic and thorough. It includes reviewing documents, conducting interviews, and visiting sites. Independent assessors appointed by the SIA lead this process. These assessors meticulously evaluate the company’s adherence to ACS standards and its capability to deliver high-quality security services.

Upon successful completion of the assessment, the security company is bestowed with ACS certification. The certification shows that the company follows professional, competent, and high-quality standards in its security operations. Clients are reassured that the company operates at elevated standards and is steadfast in delivering dependable and effective security services.

ACS Coverage:

The ACS spans a spectrum of security services, including but not limited to:

  • Manned Guarding
  • Key Holding
  • Door Supervision
  • CCTV Operation
  • Close Protection


Standards Assessed by ACS:
  1. Staffing and Training: The company needs enough trained and qualified staff, with proof of their qualifications and training records.
  2. Screening and Vetting: Rigorous procedures are necessary to check staff thoroughly for criminal records, employment history, and identity verification.
  3. Management and Operations: Evaluation of management systems and processes for effectiveness and compliance.
  4. Customer Care: Implementing a comprehensive feedback management system, leveraging efficient communication channels, and ensuring swift resolution of customer issues.
  5. Continuous Improvement: The ACS promotes ongoing advancement, urging companies to regularly assess their services and operations through training programs, performance monitoring, and iterative refinements.

The ACS accreditation is more than a certification; it is a testament to a security company’s commitment to excellence. Clients gain assurance that a certified company operates at the pinnacle of industry standards, showcasing competence and professionalism. The ACS enhances the reputation of security companies and drives the industry towards a future of consistent quality and reliability.
