Fire Alarm Servicing
A fire alarm is only as good as its ability to function during emergency situations. That’s why, at Mercury Fire & Security, we provide professional fire alarm maintenance for businesses of all sizes, ensuring your system stays compliant, reliable, and ready to protect your property and the lives within it.
Our fully qualified and accredited engineers can deliver trusted commercial fire alarm servicing across the UK to ensure your fire alarm meets legal standards and continues to perform to the highest level.


Why Fire Alarm Maintenance Matters
UK fire safety legislation, such as the Regulatory Reform (Fire Safety) Order 2005, requires businesses to maintain their alarms in line with their fire risk assessment.
British Standards 5839-1 also set out a number of best practices around fire alarm maintenance, inspections, and services that businesses should adhere to.
With regular fire alarm system maintenance, not only does it show compliance with UK legislation, but also reduces the risk of faults, false alarms, and system failure.
By scheduling routine fire alarm systems maintenance, you will:
- Keep staff and visitors safe from the threat of fire with a reliable working system
- Reduce the risk of unexpected faults and costly downtime
- Extend the lifespan of your fire alarm equipment
- Ensure compliance with legal and insurance requirements
Using our asset based job management platform, we ensure all fire alarm devices are tested correctly in line with the latest fire alarm standards, BS5839-1:2025. Our customers can then use this data to prove their compliance with regards to having all devices tested within a calendar year.
At Mercury Fire & Safety, our team are on hand to deliver essential inspections, maintenance, and servicing of your fire alarm system, ensuring you meet your legal obligations of protecting your staff and visitors from the threat of fire.

Customer experience:
We recognise that clarity and simplicity are key when it comes to managing fire and security systems. Our smart reporting tools are designed to make information easy to interpret, so clients can focus on what really matters. For larger organisations, our dedicated customer portals provide real-time access to reports, service schedules, and quotes for remedial work or upgrades, helping to keep everything organised in one place.
Efficiency:
Our software gives engineers everything they need to complete servicing quickly and accurately. With access to floor plans, site imagery, asset registers, and equipment photos, they can identify the exact location of each device before arrival. Guided maintenance checklists ensure nothing is overlooked, supporting consistent quality and compliance across every visit.

This system enables us to deliver a service built on transparency, reliability, and precision, giving clients confidence that their assets are properly maintained and records are always up to date.

Floor Plan Integration
Digital floor plan mapping helps engineers locate equipment with pinpoint accuracy, saving valuable time on site and ensuring no area is missed. These plans are also available through our customer portal, giving our maintained clients the same visibility to review layouts and identify where any issues have been found.

Our guided maintenance forms provide engineers with a clear, step-by-step process for inspections. This not only standardises the quality of each visit but also highlights patterns and potential issues by referencing previous inspection data, helping to identify faults before they become failures.
Smarter Reporting
We’ve developed a structured approach to reporting that makes technical findings straightforward to understand. Every issue is classified under one of five clear categories:
- Critical Defect
- Non-Critical Defect
- Non-Conformance
- Recommendation
- Information
This format gives clients a quick overview of priorities, supported by photographs and linked quotations that can be reviewed and approved online. The result is an efficient, transparent process that simplifies ongoing asset management.
