As the countdown to the enforcement of Martyn’s Law – The Terrorism (Protection of Premises) Act 2025 continues, organisations across the UK are reviewing how prepared they are to respond to an emergency situation.
While procedures, staff training, and risk assessments are all vital, there’s one area that’s often overlooked: the performance and maintenance of the building’s audio and emergency voice communication systems.
When every second counts, being heard can save lives. But that only happens if the technology is reliable.
Coming into force in 2027, Martyn’s Law introduces new legal duties for publicly accessible premises and events to improve preparedness for terrorist incidents.
The legislation adopts a proportionate, tiered approach based on expected occupancy:
- Standard duty premises, where 200–799 people may be present, must have documented public protection procedures covering evacuation, invacuation, lockdown, and effective communication.
- Enhanced duty premises and qualifying events with 800 or more occupants face additional obligations, including terrorism risk assessments and appropriate security measures.
Why Your Audio Systems Matter
In an emergency, alarms alone may not provide enough information. Occupants need clear, intelligible instructions that tell them exactly what action to take, whether that’s evacuating, remaining in place, or moving to a designated safe area.
That’s where Public Address and Voice Alarm (PAVA) systems can make a significant difference.
Unlike conventional PA systems, which are primarily designed for routine announcements or background audio, PAVA systems are engineered for life-safety applications. They integrate with fire detection systems, continue operating during power failures, and deliver live or pre-recorded voice messages that guide occupants quickly and clearly.
For many buildings, they form an important part of a wider emergency communication strategy.
Don’t Confuse PA with PAVA
Many buildings already have public address systems in place, but not all are suitable for emergency use.
Basic PA systems are designed for announcements and background music. They are not necessarily intended to operate during life-safety events or integrate with fire alarm infrastructure. By contrast, PAVA systems combine everyday functionality with emergency resilience, providing dependable voice messaging when occupants need clear direction the most.
Understanding this distinction is an important step when reviewing your building’s preparedness strategy.
Installation is Only Half the Story
Even the most sophisticated system can become a liability if it’s neglected.
Without regular inspection, testing, and preventative maintenance, faults may go unnoticed until the moment the system is needed most. Ageing batteries, damaged speakers, configuration issues, or degraded audio quality can all undermine performance when clear communication is critical.
A system that isn’t maintained cannot be relied upon to deliver the reassurance and guidance occupants need during an emergency.
The Hidden Costs of Poor Maintenance
Failing to maintain emergency communication systems can lead to:
- Reduced speech intelligibility during critical incidents
- Equipment or backup power failures
- Unexpected downtime and expensive reactive repairs
- Undetected faults across different zones or speakers
- Shortened equipment lifespan
- Greater operational risk and reduced confidence in emergency procedures
Supporting Compliance Through Ongoing Maintenance
Martyn’s Law isn’t about installing a single piece of technology and considering the job done. It encourages organisations to take a considered, proportionate approach to preparedness, ensuring that procedures, people, and supporting systems work together effectively.
That means any emergency communication infrastructure should be regularly tested, maintained, and reviewed as buildings evolve.
Changes to occupancy levels, layouts, or operational requirements can all affect system performance, making periodic assessments essential.
Preparing Before 2027
With enforcement approaching, now is the ideal time for facilities managers, building owners, and responsible persons to ask:
- Could we communicate clearly with everyone in the building during an emergency?
- Is our existing audio infrastructure fit for purpose?
- Are our systems tested and maintained on a regular schedule?
- Have building changes affected performance or coverage?
- Do our maintenance records demonstrate a proactive approach to system reliability?
Addressing these questions now can help reduce future risk and ensure your organisation is better prepared.
