Commercial Intruder Alarm Servicing from AVA Fire & Security

Keeping your premises secure isn’t just about installing an intruder alarm — it’s about maintaining it to UK regulatory standards. At AVA Fire & Security, we work with businesses, landlords, and property managers across South Wales and the South West to ensure intruder alarm systems stay compliant, reliable, and ready to respond.

Why Regular Servicing Matters

UK regulations BS EN 50131 and BS 4737 outline the mandatory standards for the installation and maintenance of commercial intruder alarm systems. To stay compliant (and covered by insurance), you’ll need systematic checks of:

✅ PIR sensors
✅ Door and window contacts
✅ Control panels and user interfaces
✅ Communication paths (GSM, IP, etc.)
✅ Battery health and signal reliability

When your system is maintained correctly, you reduce false alarms, avoid system downtime, and strengthen your insurance position.

Key Compliance Takeaways
- Servicing must follow BS EN 50131 & BS 4737
- Only certified engineers from NSI or SSAIB-accredited companies can legally service your system
- Maintenance includes full inspection, testing, and documentation
- Contracts typically include annual or bi-annual inspections, emergency callouts, and insurance certification
- Insurance premiums may be reduced by 5–20% with proper documentation and servicing
How Often Should You Service Your Alarm?
Most insurance policies and risk assessments require at least annual servicing — sometimes more frequently depending on your risk profile.
Every visit should include:
- Sensor testing and recalibration
- System health check
- Backup battery and power supply testing
- Review and update of control panel software
- Full service report for your compliance records
Common Issues We Catch Early
False alarms, weak signals, drained batteries, and outdated software can all compromise your protection. These issues often go unnoticed until a real event — or an inspection — reveals a fault. Regular servicing identifies and fixes problems before they become liabilities.
Insurance & Legal Compliance
Insurers expect to see:
- Current certification
- Proper documentation
- Service history performed by qualified professionals
- Evidence that your system performs as intended
Failing to meet these standards could risk invalidating your policy — and increasing premiums.
Choosing the Right Service Partner
Not all alarm companies are equal. Look for a provider that offers:
- ✅ NSI or SSAIB accreditation
- ✅ Fully insured engineers
- ✅ Fast response times
- ✅ Transparent contracts and clear reporting
- ✅ A track record with businesses like yours
At AVA Fire & Security, we offer all of the above — and local support you can count on.
What Does It Cost?
Service plans vary by system size and support requirements, but most contracts include:
- Routine inspections
- Emergency callouts
- Certification for insurers
- Compliance checks
- Software updates
We offer flexible pricing, clear service terms, and no hidden fees

Don’t Wait for a Break-In to Test Your Alarm
