Martyn’s Law, officially known as the Terrorism (Protection of Premises) Act 2025, is one of the most significant pieces of public safety legislation in recent UK history. It is designed to ensure that venues and public spaces take reasonable steps to reduce the risk of harm from acts of terrorism.
While the law is not yet in force, it is expected to be introduced in 2025. This article outlines the timeline, key responsibilities for businesses, and what you should do now to prepare.
Timeline for Martyn’s Law
Although a specific enforcement date has not been set, the government has made it clear that the legislation is moving forward. Here are the key milestones:
- May 2023 – The draft bill was published and opened for consultation.
- July 2024 – The government confirmed its continued commitment to the legislation.
- 2025 (expected) – The law is anticipated to come into force, requiring venues and event operators to comply with new public protection duties.
The Security Industry Authority (SIA), which will oversee enforcement, is currently finalising processes related to guidance, compliance inspections, and penalties.
Who Will Mrtyn's Law Apply To?
Martyn’s Law will apply to public venues and events based on their capacity:
Standard Tier (100–799 capacity):
These venues will be required to introduce basic safety procedures, including evacuation plans, lockdown protocols, and staff communication systems.
Enhanced Tier (800+ capacity):
Larger venues will face more extensive obligations, such as formal risk assessments, security infrastructure reviews, monitoring of access points, and protective measures for people and information.
The law is likely to affect a wide range of venues, including entertainment arenas, shopping centres, places of worship, schools, healthcare facilities, transport hubs, and public events.
Why Is Martyn’s Law Being Introduced?
Martyn’s Law is named in honour of Martyn Hett, one of the victims of the 2017 Manchester Arena terrorist attack. The legislation is a response to the gaps identified in venue preparedness at the time. It aims to make counter-terrorism a mandatory part of venue and event management, so that staff and the public are better protected.
What Happens If You Don’t Comply?
Non-compliance will carry significant financial penalties:
- £5,000 for failing to attend interviews or answer questions
- £10,000 for breaches involving standard-tier venues
- Up to £18 million or 5% of global turnover for enhanced-tier venues or qualifying events
In addition, venues must submit detailed documentation to the SIA outlining their procedures, risk assessments, and ongoing reviews. These documents must be kept up to date and re-submitted within 30 days of any revisions.
How to Prepare Now
With implementation expected in 2025, now is the time to act:
- Identify whether your premises fall under Standard or Enhanced Tier
- Appoint a responsible person for compliance
- Prepare public protection procedures and plans
- Document your emergency response and mitigation measures
- Engage with a qualified security consultant for support and staff training
