If you’re responsible for a commercial property, this is one of those questions that’s easy to overlook — until it becomes a problem.
How often should your fire alarm actually be serviced?
It’s not just a recommendation. In the UK, fire alarm maintenance is a legal responsibility. And getting it wrong can lead to failed inspections, invalid insurance, or worse — a system that doesn’t perform when it’s needed most.
What Does UK Law Say About Fire Alarm Servicing?
Fire alarm systems in the UK are governed by the Regulatory Reform (Fire Safety) Order 2005, which places responsibility on the “Responsible Person” to ensure fire safety systems are properly maintained.
In practical terms, this means your fire alarm system must be:
Regularly tested
Properly maintained
Fully operational at all times
To support this, most systems follow the British Standard:
👉 BS 5839
How Often Should Fire Alarms Be Serviced?
According to UK best practice:
🔧 Professional servicing:
At least every 6 months for most commercial premises
Quarterly servicing may be required for higher-risk environments
🔍 Routine checks:
Weekly fire alarm tests (usually one call point)
Monthly checks of emergency lighting and backup systems
These checks ensure your system remains compliant and reliable.
What Happens During a Fire Alarm Service?
A professional fire alarm service isn’t just a quick check — it’s a full system review.
Typically, this includes:
Testing detectors and call points
Checking control panels and fault logs
Inspecting batteries and power supplies
Verifying system performance
Identifying any faults or compliance issues
Everything should be recorded in your fire logbook — something inspectors will often ask to see.
Who Is Responsible for Fire Alarm Maintenance?
The responsibility sits with the Responsible Person, which may be:
Business owners
Employers
Landlords
Facilities managers
Managing agents
Even if maintenance is outsourced, legal responsibility remains with you.
What Happens If You Don’t Service Your Fire Alarm?
This is where things become serious.
Failing to properly maintain your fire alarm system can lead to:
Enforcement notices
Fines or prosecution
Failed fire safety inspections
Insurance complications
Increased risk to life and property
In many cases, businesses only realise there’s an issue when an inspection highlights it.
Why Regular Servicing Matters
Beyond compliance, regular servicing ensures:
Early detection of faults
Reduced false alarms
Longer system lifespan
Confidence that your system will work in an emergency
It’s not just about ticking a box — it’s about reliability.
