Why Fire Alarm Servicing Matters in the Workplace
Fire alarms are one of the most critical life safety systems in any business.
They provide vital early warning in the event of a fire — but only if they’re correctly maintained and regularly tested.
A working fire alarm can be the difference between a safe evacuation and a serious incident.
Without proper servicing, faults can go unnoticed, and the system may not operate when it’s needed most.
That’s why every business in Harefield must take fire alarm maintenance seriously — not just for legal compliance, but to protect people and property.
Servicing Your Alarm System Helps:
Safeguard lives and assets
Minimise disruption and downtime
Prove compliance with fire safety regulations
Avoid costly enforcement action or insurance issues
UK Legal Requirements for Fire Alarms
Under the Regulatory Reform (Fire Safety) Order 2005, businesses in Harefield are required to:
Install a suitable fire detection and alarm system
Ensure the system is maintained by a competent person
Test the system weekly and service it at recommended intervals
Keep clear records of inspections, tests, and maintenance
Take action on faults and non-conformities
At ESI: Fire Safety, we carry out all fire alarm servicing in accordance with the latest BS 5839-1:2025 standard, ensuring your system is compliant, reliable, and up to date with the most current fire safety best practices.
How Often Should Fire Alarms Be Serviced?
To comply with BS 5839-1:2025, your fire alarm system should be:
Tested weekly by a responsible person on-site
Serviced at least every 6 months by a competent, qualified engineer
Inspected quarterly in higher-risk or complex premises (best practice)
Regular servicing ensures components such as detectors, call points, sounders, and batteries are functioning properly — and that your system will perform as expected in a fire emergency.

Visual inspection of all accessible components
