Martyn's Law software for readiness and evidence

EventGen is Martyn's Law readiness and evidence-management software for events. It helps organisers scope a case, map responsibility, maintain a workforce register, publish procedures, collect briefing acknowledgements, and export evidence. It does not certify compliance and is not legal advice.

Martyn's Law is the common name for the UK Terrorism (Protection of Premises) Act 2025, which received Royal Assent in April 2025. It requires those responsible for qualifying public premises and events to take proportionate steps to reduce the risk of harm from a terrorist attack - including having public-protection procedures and, for larger premises and events, additional measures and documentation. It is named after Martyn Hett, one of the victims of the 2017 Manchester Arena attack.

Premises and events have different tests. Qualifying premises generally have a standard tier at 200–799 people and an enhanced tier at 800 or more, based on people reasonably expected at the same time and subject to exceptions. A qualifying event requires 800 or more people reasonably expected at the same time, including staff, plus public access, entry checks, and the other statutory conditions; it must not already take place at enhanced-tier premises or excluded premises. Total ticket sales alone do not determine scope. Confirm your circumstances against the official guidance.

As checked on 9 October 2026, the SIA expects the Act to come into force in spring 2027 and will confirm the exact date. Its substantive public-protection duties are not yet in force. Organisers can use the preparation period to assess scope, organise procedures, brief their workforce, and collect readiness evidence.

It manages the operational side of readiness as a case in your dashboard: scope assessment, responsibility mapping, an event-day workforce register (including agency staff and volunteers), published procedures with per-person briefing acknowledgements, and an exportable evidence pack for inspection or review.

The specialist Martyn's Law case, workforce register, briefings, procedures, and evidence pack remain their own compliance workflow. If a participant needs to submit or accept supporting evidence, the organiser can manage that participant-facing document or form through Obligations Management, with its audience, enforcement, Campaign reminders, progress, and optional AI review for uploaded documents.

No. EventGen manages evidence and readiness - it records what you did and lets you demonstrate it. It does not certify compliance with the Act and is not a substitute for legal advice.

Anyone working your event on the day can be registered in the workforce register and asked to acknowledge the briefing - including agency staff and volunteers who don't have EventGen accounts. They acknowledge via a briefing code, so there's no account setup.
