This learning path takes you through the regulatory framework for security and investigation businesses in order. Each step links to a guide that covers one part of your obligations. Follow them in sequence to build a complete picture.

Step 1 — Work out which rules apply

Identify whether your business falls under SIA licensing, installer certification, or both, and understand the universal workplace duties that apply to every security business.

Step 2 — Set up your workplace safely

Work through the five universal duties every security and investigation business must meet: health and safety, fire safety, employers' liability insurance, equality and data protection.

Step 3 — Meet your sector-specific duties

If you provide licensable security activities, install alarm or CCTV systems, or carry out private investigations, follow this guide for the SIA licensing regime, the Approved Contractor Scheme, installer certification and the current status of private investigator licensing.

Step 4 — Confirm you are compliant

Work through the compliance checklist to confirm every obligation is in place before you begin or continue trading.
