If you manage a business, rental property, or public building in the UK, keeping your fire alarm system in good working order isn’t optional—it’s a legal requirement under the Regulatory Reform (Fire Safety) Order 2005.
However, many people confuse fire alarm testing with fire alarm servicing. While both are essential to ensuring your fire alarm system remains reliable and compliant, they are not the same. Understanding the difference can help you stay on the right side of the law and, more importantly, help protect lives and property.
This article explains what each process involves, who should carry them out, and why both are necessary.
What is a Fire Alarm Test?
A fire alarm test is a routine check—usually performed weekly—to make sure the system is functioning as expected. It’s a simple and brief procedure that focuses on confirming the alarm sounds can be heard clearly throughout the building.
A typical fire alarm test includes:
-
Activating a manual call point (break glass unit) to trigger the alarm.
-
Checking that the alarm is audible in all areas.
-
Resetting the system once the test is complete.
-
Recording the test in your fire safety logbook.
This type of test should be carried out by a competent person on-site, such as the designated fire warden, building manager, or responsible person as defined in fire safety legislation. There is no need for a specialist fire alarm engineer to attend.
To comply with British Standard BS 5839-1, a fire alarm test should be performed once a week. Each week, a different call point should be tested to ensure every device is checked over time.
Weekly testing is vital for early detection of faults, and it demonstrates your ongoing commitment to fire safety.
What is a Fire Alarm Service?
In contrast, a fire alarm service is a more comprehensive inspection and maintenance process carried out by a qualified fire alarm engineer. It involves a detailed check of all components in the system and ensures everything complies with current regulations and industry standards.
A fire alarm service typically involves:
-
Inspecting the control panel, detectors, call points, sounders, wiring, and connections.
-
Testing the function of each device across all zones.
-
Cleaning detectors to prevent dust-related faults or false alarms.
-
Checking and, if necessary, replacing standby batteries.
-
Verifying cause-and-effect operations, such as automatic door releases or shutdowns.
-
Providing a full service report with details of any faults, repairs carried out, and recommendations.
This should be carried out by a qualified fire protection company or certified engineer who understands BS 5839-1 and has experience working with fire detection systems.
BS 5839-1 recommends that fire alarm servicing is carried out at least every six months. In higher-risk environments or larger buildings, more frequent servicing may be needed.
Regular servicing ensures your system remains compliant, effective, and ready to respond in an emergency. It can also help you avoid unexpected failures, fines, or invalidated insurance claims.
Why You Need Both Testing and Servicing
It’s not a case of choosing between the two—both fire alarm testing and fire alarm servicing play critical roles in your fire safety strategy.
Weekly testing ensures your system is operational and alerts you to any immediate issues. Professional servicing provides a deeper level of maintenance and compliance assurance, identifying problems that might not be obvious during a routine test.
Skipping either could result in:
-
A system that appears to work but fails during a real emergency.
-
Breaches of legal responsibilities under the Fire Safety Order.
-
Challenges when making an insurance claim related to fire damage.
-
Increased risk to people, property, and business continuity.
In Summary
Fire alarm testing and servicing are not interchangeable—they serve different purposes and are both legally and practically necessary. By carrying out weekly tests and arranging professional services at least twice a year, you can ensure your system remains compliant, reliable, and fully prepared to protect lives.
