Fire alarm systems play an essential role in safeguarding lives and property. Whether in commercial buildings, residential blocks, or industrial sites, these systems are designed to detect early signs of fire and alert occupants, enabling quick evacuation and emergency response. However, like any technical system, fire alarms require regular maintenance and servicing to ensure they remain effective. Fire alarm servicing is not just a best practice—it is a legal obligation under UK fire safety law.

In this post, we’ll explore why fire alarm servicing is vital, what it involves, how often it should be performed, and what benefits it brings to property owners and businesses.

Understanding Fire Alarm Servicing

Fire alarm servicing refers to the scheduled inspection, testing, and maintenance of a building’s fire alarm system. It is a proactive measure that ensures every component of the system functions correctly. This includes smoke and heat detectors, control panels, sounders, manual call points, power supplies, and communication links. The goal is to identify any faults, wear and tear, or potential failures before they lead to serious consequences.

Fire alarms that are not regularly serviced are more likely to malfunction. This may result in missed detections, delayed alerts, or false alarms that cause unnecessary disruptions and costs. In worst-case scenarios, neglected fire systems can fail entirely during an emergency.

Legal Requirements in the UK

UK legislation requires that all commercial and most residential buildings comply with fire safety standards outlined in the Regulatory Reform (Fire Safety) Order 2005. One of the key components of compliance is ensuring that fire detection and alarm systems are adequately maintained.

The British Standard BS 5839-1:2017 outlines the minimum requirements for the servicing of fire alarm systems in non-domestic premises. It recommends that fire alarms be inspected by a competent person at least twice a year. In some high-risk settings, quarterly inspections may be necessary.

Failure to comply with these standards can result in enforcement actions by fire authorities, including fines, prohibition notices, and in severe cases, criminal prosecution. Additionally, insurance companies may reject claims if systems are found to be poorly maintained.

What Happens During a Fire Alarm Service?

A professional fire alarm service includes a thorough check of the entire system. A certified technician will inspect each component to verify that it operates according to its intended function.

This process generally includes:

• Visual inspection of all fire detection equipment and control units
• Testing of smoke and heat detectors to confirm proper sensitivity and response
• Testing of manual call points for correct activation
• Function testing of alarm sounders and strobes
• Verification of control panel indicators and battery power supply
• Cleaning of sensors to remove dust or contaminants
• Checking system logbooks and updating service records

Any faults identified during the inspection will be logged, and recommendations will be made for corrective action. If a fault presents an immediate safety risk, it should be repaired or replaced without delay.

Frequency of Fire Alarm Servicing

The standard frequency recommended by BS 5839 is every six months. However, this is the minimum standard. In environments where the risk of fire is higher or where the system is subject to frequent use, more frequent servicing may be appropriate.

In addition to biannual servicing by professionals, a responsible person within the building should perform weekly tests. These tests typically involve activating a manual call point to ensure that the alarm sounds and that the system panel responds appropriately. Each test should target a different call point each week, with results recorded in the fire logbook.

Monthly visual checks of backup batteries and the system’s power supply are also advised to confirm continuous operation.

Common Issues Found During Servicing

Routine servicing helps uncover a variety of issues that can affect the reliability of fire alarm systems. Some common problems include:

• Dead or failing batteries in control panels
• Obstructed or dusty smoke detectors
• Faulty wiring or loose connections
• Disabled sounders or strobes
• Programming errors on the control panel
• Outdated or missing signage and call points

Left unresolved, these faults can compromise the entire system and increase the risk of harm during a fire emergency. Regular servicing ensures these problems are addressed early.

The Risks of Skipping Fire Alarm Servicing

Neglecting fire alarm maintenance comes with serious consequences. Beyond the potential legal penalties and insurance implications, there is the fundamental risk to life and property. A non-functioning alarm could delay emergency evacuation, leading to injuries or fatalities.

False alarms are another consequence of poor maintenance. These can disrupt operations, lead to evacuation fatigue, and reduce response urgency in actual emergencies. Repeated false alarms may also result in fines from local fire brigades if they are forced to respond unnecessarily.

From a business perspective, reputational damage, operational downtime, and liability claims could all result from an avoidable failure in fire protection systems.

How to Choose a Fire Alarm Servicing Provider

Choosing a reliable and experienced provider is critical for maintaining fire alarm systems to the appropriate standards. When selecting a service provider, consider the following:

• Are their technicians certified and experienced in BS 5839 standards?
• Do they offer tailored service plans based on building size and usage?
• Are emergency call-outs available if faults occur outside routine inspections?
• Do they provide clear service reports and documentation for compliance?
• Are they insured and accredited by relevant fire safety organizations?
