From Legislation to Action: Key Security Responsibilities

Here’s the practical bit. Understand your category, write a plan that people can actually follow, and make sure it works in the real world (Martyn's law or Terrorism (Protection of Premises) Act 2025).

1) Identify your venue’s category

Capacity and usage drive what’s expected. If you want the background and “why”, start with Why Martyn’s Law exists.

2) Implement a lockdown plan

Keep it clear and brief: who triggers, who leads, where people go, and how you communicate. For an alarm-first view, see The role of lockdown alarms.

3) Lockdown alarms in compliance

The duty is about effective communication under stress. A dedicated lockdown alarm system is the simplest way to meet that requirement without confusion.

4) Train your staff

  • How to trigger from anywhere (fob, wall point, mobile trigger).
  • Where to direct the public (safe areas).
  • How to keep messaging calm and consistent.

5) Test and maintain

Short drills. Regular checks. Fix what fails. Record what you do.
