Martyn’s Law: A Guide for Installers

Are you ready for Martyn's law?

Martyn’s law, officially the Terrorism (Protection of Premises) Act 2025 is landmark UK legislation designed to improve public safety at publicly accessible venues and events. It is named after
Martyn Hett, one of the 22 victims of the 2017 Manchester arena terrorist attack, and was championed by his mother Figen Murray.

The law places a legal duty on venue operators to take reasonable and proportionate steps to reduce the risk of terrorist attacks. As a result, many venues will need to upgrade or introduce security measures — creating a clear opportunity for professional security installers.

What we know about implementation timings

• A 24-month implementation period is expected once the law comes into force
• Full compliance is likely to be required around 2027
• Statutory guidance is expected in early 2026
• The Security Industry Authority (SIA) will regulate and enforce compliance

Where does Martyn's law apply?

The law applies to publicly accessible venues and events, split into two tiers based on capacity:

Typical venues in scope include:

• Theatres, cinemas, and entertainment venues
• Retail centres and large stores
• Hotels, bars, restaurants, and nightclubs 
• Stadiums and sports grounds
• Universities and education sites 
• Places of worship
• Visitor attractions and events

Protective Security Recommendations: Standard Tier (200–799 capacity) 

The emphasis at standard tier is on simple, reliable, and affordable solutions that support a rapid response. Requirements focus on procedures, staff training, and evacuation planning rather than complex infrastructure.

• Communication: PA or voice alarm systems, two way radios, mass notification apps 
• CCTV: Entry level IP CCTV with recording and remote viewing 
• Signage & Wayfinding: Clearly marked exits, evacuation routes, and lockdown instructions 
• Lighting: Emergency lighting and basic external security lighting 
• Access Control: Door closers, basic electronic locks, key fob or keypad systems on critical doors
• Training Support: Access to ACT (Action Counters Terrorism) elearning for staff

Installer Tip: Sell solutions that support the “Run, Hide, Tell” approach — clear escape routes, doors that can be secured quickly, and reliable communication for staff. Keep it simple, affordable, and easy to maintain. 

Protective security recommendations: enhanced tier (800+ capacity) 

Enhanced tier venues need integrated, professional-grade security systems and ongoing expert support. These sites require documented risk assessments, formal security plans, and physical and electronic security measures working together.

• Advanced CCTV:  High resolution cameras with analytics (crowd monitoring, behaviour detection, etc.) 
• Access Control:  Networked access control, turnstiles, visitor management, mantrap entries
• Intruder & Perimeter Detection: PIRs, glass-break sensors, perimeter beams and fencing sensors
• Hostile Vehicle Mitigation (HVM): Bollards, rated planters, vehicle blockers and barriers  
• Screening:  Walk-through metal detectors, Xray scanners, handheld wands 
• Blast Mitigation:  Anti-shatter film, reinforced glazing, protective façade elements 
• Lockdown Systems: Automated door locking, panic hardware, designated secure refuge areas 
• Mass Notification: Integrated PA/VA systems, digital signage alerts, SMS and appbased alerts
• Control & Monitoring: Central control rooms, alarm receiving centre (ARC) integration

Installer Tip: Position yourself as more than just an installer. Help clients identify risks during site surveys and match solutions to their legal obligations. The most successful installers will become trusted, long-term security partners.
