Martyn’s Law Tiers Explained in Under 3 Minutes
The security landscape in the United Kingdom is undergoing its most significant shift in decades. Under the Terrorism (Protection of Premises) Act 2025: widely known as Martyn’s Law: thousands of venues across the country are now legally required to enhance their preparedness against terrorist threats. This legislation is not a suggestion; it is a mandatory framework designed to ensure public safety in accessible locations.
At KGFM Ltd, we understand that navigating new legislation can be daunting for business owners and facilities managers. Our expertise in martyn's law compliance and security guard services positions us as the premier choice for organisations looking to bridge the gap between current operations and new legal obligations. This guide breaks down the two-tier system of Martyn’s Law to give you the clarity you need to act immediately.
THE TWO-TIER SYSTEM: WHERE DO YOU FALL?
The core of Martyn’s Law is a tiered approach based on the capacity of the premises. This ensures that the burden of compliance is proportionate to the potential risk and the resources of the venue. Whether you manage a small local community hall or a massive stadium, you must identify your tier to begin the compliance process.
1. THE STANDARD TIER (200–799 PEOPLE)
The Standard Tier applies to qualifying public premises with a capacity of 200 to 799 people. The government’s objective for this tier is to implement straightforward, low-cost security measures that can be integrated into daily operations without requiring significant financial investment or structural changes.
KEY REQUIREMENTS FOR THE STANDARD TIER:
- Procedural Preparedness: Venues must establish clear procedures for evacuation, invacuation (lockdown), and internal/external communication during an incident.
- Staff Awareness: Employees must be trained on attack response protocols. This includes identifying safe routes and knowing how to secure the premises (e.g., locking doors and closing shutters).
- Documentation: While less intensive than the Enhanced Tier, Standard Tier venues must still demonstrate that they have considered the risks and implemented basic response plans.
For many in the Standard Tier, the focus is on "readiness." It is about ensuring that if the worst happens, staff are not caught off guard. KGFM Ltd provides tailor-made guidance for Standard Tier venues, ensuring your team is professionally trained and your procedures meet all martyn's law compliance standards.

2. THE ENHANCED TIER (800+ PEOPLE)
The Enhanced Tier applies to larger venues and events with a capacity of 800 or more people. Due to the higher potential impact of an incident at these locations, the requirements are significantly more rigorous. Failure to comply at this level carries heavy penalties and significant reputational risk.
KEY REQUIREMENTS FOR THE ENHANCED TIER:
- Detailed Terrorism Risk Assessments: A formal, site-specific risk assessment must be conducted to identify vulnerabilities and potential attack vectors.
- Security Plans: A comprehensive security plan must be documented, outlining both procedural and physical security measures.
- Physical Security Enhancements: Unlike the Standard Tier, Enhanced Tier venues may be required to implement physical measures such as CCTV, controlled access points, bollards, and bag checks where "reasonably practicable."
- Designated Senior Individual: Each venue must have a named senior person responsible for compliance.
- SIA Collaboration: Plans and assessments must be submitted to the Security Industry Authority (SIA) for assessment and audit.
Managing an Enhanced Tier venue requires a level of expertise that goes beyond basic facility management. This is where KGFM Ltd excels. Our security guard services are built on SIA Standards, providing the "manned guarding" and professional oversight necessary to satisfy the most stringent requirements of the Enhanced Tier.
THE IMPORTANCE OF "REASONABLY PRACTICABLE"
A phrase you will encounter frequently in the Terrorism (Protection of Premises) Bill is "reasonably practicable." This is the legal threshold for compliance. It means that while you are required to take action, the law acknowledges that security measures must be balanced against the resources available and the specific nature of the venue.
However, "reasonably practicable" is not an excuse for inaction. It is a call for a professional evaluation of what can and should be done. KGFM Ltd works closely with clients to determine exactly what this means for their specific site, ensuring that security solutions are both effective and sustainable.

THE ROLE OF PROFESSIONAL SECURITY GUARD SERVICES
While the law focuses on procedures and plans, the human element remains the most critical factor in security. Professional security guard services are the frontline of Martyn’s Law compliance.
At KGFM Ltd, our guards are more than just a presence; they are professionally trained assets integrated into your compliance strategy. For Enhanced Tier venues, manned guarding provides the necessary capacity for:
- Conducting thorough bag and person searches.
- Managing complex access control systems.
- Executing rapid lockdown procedures.
- Providing real-time intelligence and communication during an incident.
By employing SIA-approved professionals, you ensure that your venue isn't just following the letter of the law, but truly protecting its patrons. Our staff undergo continuous training to stay ahead of evolving threats, making KGFM the most reliable partner for your security needs.
STEPS TO TAKE NOW FOR MARTYN’S LAW COMPLIANCE
Do not wait for an inspection or an incident to begin your journey toward compliance. The following steps should be taken immediately:
- Confirm Your Capacity: Calculate the maximum safe capacity of your premises to determine if you fall into the Standard (200-799) or Enhanced (800+) tier.
- Review Existing Procedures: Look at your current fire safety and emergency evacuation plans. How would they adapt to a terrorist incident?
- Engage with Experts: Contact a security professional. KGFM Ltd offers comprehensive site surveys to identify gaps in your current security posture.
- Staff Training: Begin educating your staff on basic counter-terrorism awareness. Use official resources like the ProtectUK platform as a starting point.
- Audit Your Security Guard Services: If you currently use security staff, ensure they are trained to SIA Standards and are capable of fulfilling the requirements of the new legislation.
