Why This Certificate Matters

SIA ACS approval puts your business on the SIA's official list. Clients and government buyers check this list before they hire a security company.

Without it, you could lose contracts to companies that already hold ACS, even if your work is just as good. Clients simply can't trust what they can't verify.

SIA ACS FAQ's

Working with an experienced consultant significantly reduces the risk of failing and speeds up the entire process.
The SIA Approved Contractor Scheme is a voluntary quality standard for private security companies in the UK, managed by the Security Industry Authority. It assesses businesses against 78 achievement indicators covering staff vetting, training, health and safety, financial management, and operational procedures. Achieving ACS approval places your company on the official SIA register, which is checked by clients, government buyers, and large procurement teams before awarding security contracts.
The benefits of becoming an SIA-approved contractor include improved credibility, access to higher-value contracts, and increased client confidence. It also strengthens your business systems, operational processes, and competitive position within the UK security industry.
You will need a signed health and safety policy, staff vetting records confirming BS 7858 screening, SIA licence records for all operational staff and directors, training and competence evidence, financial accounts, and a quality management policy. You will also need documented operational procedures, complaint handling systems, and evidence of regular management reviews. All documents must be current, properly maintained, and specific to your actual business operations rather than generic templates.
