The Terrorism (Protection of Premises) Act 2025, commonly referred to as Martyn's Law, mandates comprehensive emergency response procedures for educational institutions with a capacity of 200 or more persons. Implementation of these requirements presents several distinct challenges for school leadership.
Understanding Your School’s Requirements
Guidance Interpretation
The Department for Education guidance provides statutory requirements but offers limited prescriptive instruction. Schools must translate legislative requirements into operational procedures appropriate to their individual circumstances.
Resource Allocation
Implementation requires capital investment for infrastructure, procurement timescales, and dedicated staff training. Schools must balance compliance requirements against competing budget pressures and operational constraints.
Solution Suitability
Short-term or standalone measures may satisfy immediate requirements, but often lack the resilience, scalability and reliability needed to support coordinated emergency communication across larger or multi-building school sites.
Technical Integration
Existing telecommunications infrastructure may not be designed to support emergency communication protocols. Solutions must integrate with or operate independently from established systems according to school requirements.

The Critical Role of Communication Infrastructure
Emergency response procedures for evacuation, invacuation, and lockdown all depend upon effective communication infrastructure. Communication is not an ancillary requirement; it is the operational foundation that enables coordinated emergency response across the school environment.
✔ Immediate Message Delivery ensures all staff receive consistent, pre-composed instructions simultaneously rather than relying on verbal relay or individual interpretation.
✔ Targeted Zone Communication allows differentiated instruction to specific building areas, ensuring staff and students in each location receive appropriate, contextually relevant direction.
✔ Priority Alert Functionality delivers critical notifications that interrupt routine communications, ensuring no staff member misses essential information regardless of their current activity.
✔ Documented Procedures provide schools with records of training, testing, and system capabilities for inspection and compliance verification purposes.
✔ Reliable Scaling ensures communication infrastructure functions reliably, whether coordinating 30 staff or 300, without degradation or reliance on manual relay processes.

Frequently Asked Questions
Q: Does Martyn’s Law apply to our school?
A: Martyn’s Law applies to schools with a capacity of 200 or more people. This includes most secondary schools and many primary schools. If your school expects to have 200+ people on site at any time (including events), you must comply.
Q: What does “effective communication” mean?
A: Effective communication means staff can be alerted quickly and given clear instructions during an emergency. This must work for evacuation (getting people out), invacuation (moving people to safe zones inside), and lockdown (securing the building). Walkie-talkies or word-of-mouth are not sufficient because they do not scale reliably across a whole school.
Q: Can we use walkie-talkies to meet the requirement?
A: Walkie-talkies alone do not meet Martyn’s Law because they cannot reliably communicate with all staff at once, cannot deliver pre-recorded messages, and do not provide documentation of procedures. A proper emergency communication system is required to meet the law’s standard for “effective communication.”
Q: Will this disrupt our existing phone system?
A: No. SelectVoice integrates with your existing system, and Algo works as a standalone solution. Either way, emergency communication runs independently, so it does not interfere with day-to-day phone use. We’ll design it specifically for your school’s setup.
Q: How long does installation take?
A: Installation timescale depends on your school’s size and existing infrastructure. Most schools can be operational within 2-4 weeks. We’ll provide a detailed timeline during the planning phase. Early action means you have time for staff training and procedure refinement before April 2027.
Q: Will staff training be included?
A: Yes. We provide comprehensive staff training, documentation, and templates. We’ll help you design your emergency procedures, create pre-recorded messages, and build confidence in your team. This is part of our support, not an add-on.
Q: How much does this cost?
A: Cost depends on your school’s size, existing infrastructure, and chosen solution. We’ll provide a detailed, transparent quote after understanding your needs. Many schools view this as an essential safeguarding investment, not an optional expense. Get in touch for a consultation.
