Martyn’s Law checklist – preparing for implementationimpact hr ident

Martyn’s Law (the Terrorism (Protection of Premises) Act 2025) introduces a new legal duty for organisations responsible for publicly accessible premises and events to take proportionate steps to reduce the risk of harm from terrorist incidents.

Although the Protect Duty is not yet in force, the Government has confirmed a minimum implementation period. This provides organisations with a valuable opportunity to prepare in a structured, proportionate way.

The impact HR Martyn’s Law checklist has been designed to support organisations during this period by helping them understand what is likely to be required, identify gaps, and demonstrate early due diligence.

Martyn’s Law checklist

What this checklist is for

This checklist provides a practical preparation framework, not a pass-or-fail audit.

It is designed to help organisations:

  • Understand anticipated duties under Martyn’s Law
  • Identify whether premises or events are likely to fall within scope
  • Prepare proportionate arrangements aligned to tiered requirements
  • Support risk management and governance discussions
  • Evidence reasonable steps taken during the implementation period

The checklist reflects the Government’s emphasis on proportionate, risk-based preparation, rather than prescriptive or security-heavy solutions.

  • Who the checklist is designed for

    The checklist is suitable for organisations that:

    • Control publicly accessible premises or events
    • Expect 200 or more people to be present at peak times
    • Operate venues, facilities or events open to the public
    • Have responsibilities for health and safety, facilities, events or operations

    It is particularly relevant for organisations in sectors such as hospitality, retail, leisure, education, events, culture, faith and visitor attractions.
