For anyone responsible for a larger venue, Martyn’s Law has moved from a distant piece of legislation to a pressing operational reality. While much of the early conversation focused on the Standard Tier that captures smaller premises, it is the Enhanced Tier that places the most significant duties on the biggest venues, and getting it right demands genuine planning rather than a box-ticking exercise. Understanding the Martyn’s Law Enhanced Tier is essential for any organisation operating at scale, and in this guide we set out what it involves, who it applies to, and how to prepare properly. As security specialists who advise venues across the UK, this is a conversation we are having with clients every week.
A Quick Recap: What Is Martyn’s Law?
Martyn’s Law, formally the Terrorism (Protection of Premises) Act, is named in memory of Martyn Hett, one of the victims of the 2017 Manchester Arena attack. Its purpose is to improve public safety by requiring those responsible for certain premises and events to take proportionate steps to prepare for, and reduce the harm from, a potential terrorist attack. It marks a significant shift, placing a clear legal duty on venues to think seriously about protective security.
The legislation is deliberately tiered so that the requirements are proportionate to the size of the venue. Smaller qualifying premises fall under the Standard Tier, with lighter-touch obligations, while larger premises fall under the Enhanced Tier, where the duties are more substantial. Knowing which tier you sit in is the essential first step, because it determines exactly what is expected of you.

Which Venues Fall Under The Enhanced Tier?
The Enhanced Tier is aimed at larger premises and events, those where a greater number of people gather and where, consequently, more thorough preparation is expected. Broadly, it applies to qualifying premises and events with a capacity at or above the higher threshold set out in the legislation, typically much larger gatherings than those captured by the Standard Tier.
In practice this brings a wide range of venues into scope. Think of large entertainment and sports venues, sizeable conference and exhibition centres, major visitor attractions, and other premises where substantial crowds assemble. If your venue regularly hosts events at this scale, it is very likely that the Enhanced Tier applies to you, and the responsibilities that come with it are correspondingly more detailed. Because the thresholds and definitions carry real legal weight, it is always worth confirming your position with a professional rather than assuming.
Key Requirements Of The Enhanced Tier
The Enhanced Tier goes beyond the awareness-focused expectations of the Standard Tier and asks for a more structured, documented approach to protective security. The core duties generally include:
- A documented risk assessment: assessing the specific terrorism risks to your venue and the vulnerabilities that need addressing.
- A security plan: setting out the measures you have in place to reduce the risk of harm and respond effectively in an incident.
- Appropriate protective measures: putting practical steps in place, which may cover matters such as monitoring, access control, physical security and incident response.
- Staff training and preparedness: ensuring your people understand the plan and know how to act, because even the best plan fails if staff are not prepared.
- Nominating a responsible person: a clear point of accountability for compliance within your organisation.
The thread running through all of these is documentation and evidence. It is not enough to have good intentions or informal arrangements; the Enhanced Tier expects you to be able to demonstrate what you have assessed, what you have put in place, and how your staff are prepared.
How To Prepare Your Venue For Enhanced Tier Compliance
Preparation is far easier when approached methodically and early, rather than as a last-minute scramble. The sensible starting point is a thorough, professional risk assessment that reflects the reality of your venue, its layout, its events and its people. From there, a practical security plan can be built that is proportionate to the risks you have actually identified.
Just as important is embedding that plan into daily operations. Protective measures need to be appropriate and workable, and staff at every level need training so that the plan lives in practice, not just on paper. We say to clients regularly that compliance and genuine safety are the same journey: a venue that prepares properly for Martyn’s Law is not simply avoiding a legal problem, it is becoming a genuinely safer place for the public. Bringing in experienced security professionals early takes the uncertainty out of the process and ensures nothing important is overlooked.

Frequently Asked Questions About The Martyn’s Law Enhanced Tier
What is the difference between the Standard and Enhanced Tiers?
The Standard Tier applies to smaller qualifying premises and focuses on awareness and simple, proportionate steps. The Enhanced Tier applies to larger venues and requires a documented risk assessment, a security plan and more substantial protective measures. The duties scale up with the size of the venue.
How do I know if my venue is in the Enhanced Tier?
It depends on your venue’s capacity and the nature of your events against the thresholds in the legislation. Larger venues hosting substantial crowds are most likely to fall into the Enhanced Tier. Because the definitions matter legally, it is best to confirm your position with a security professional.
Do I need to train all my staff?
Staff preparedness is central to the Enhanced Tier. Your people need to understand the security plan and know how to respond, so appropriate training across your team is an essential part of compliance and of keeping the public safe.
When do I need to be compliant?
Martyn’s Law includes an implementation period before the duties are fully enforced, but preparation takes time, especially for larger venues. It is far wiser to start early than to wait, so that your risk assessment, plan and training are properly in place well ahead of any deadline.
