If you own or manage a business in Surrey — whether it’s a shop in Caterham, an office in Guildford, a care home in Farnham, or a warehouse in Leatherhead — your fire alarm system is your first line of defence when something goes wrong.
But here’s a question many business owners get wrong: how often should fire alarms actually be tested and serviced?
Too many think it’s enough to press the red button every now and then or wait until the system starts beeping. Unfortunately, that’s not how the law (or Surrey Fire & Rescue) sees it.
Let’s make this simple — we’ll walk through exactly how often to test, service, and record maintenance of your fire alarms, why it matters, and how to make sure you stay compliant under BS 5839-1:2025.
The Legal Duty for Fire Alarm Testing
Under the Regulatory Reform (Fire Safety) Order 2005, every business or non-domestic premises in Surrey must have:
✅ An appropriate fire detection and alarm system in place, and
✅ A maintenance regime to ensure it works properly at all times.
The law places the duty on the Responsible Person — usually the employer, landlord, or managing agent — to keep systems maintained “in efficient working order.”
Failing to do so can result in Enforcement Notices, Prohibition Orders, or even prosecution if people are put at risk.
Surrey Fire & Rescue inspectors will ask for evidence of testing and maintenance records during an audit — not just a working alarm.

The Key British Standard: BS 5839-1:2025
The national standard governing commercial fire alarms is BS 5839-1:2025, which sets out how systems must be designed, installed, and maintained.
It defines the testing and servicing intervals that ensure your alarm system stays effective and legally compliant.
The standard divides maintenance into weekly, quarterly, and annual checks — each with a specific purpose.
🔹 Weekly Fire Alarm Testing
This is your in-house test — a quick, simple check to make sure everything’s functioning.
What to do:
- Test at least one manual call point each week.
- Rotate through different call points so every one is tested over time.
- Confirm that alarm sounders and visual indicators operate correctly.
- Record the test in your fire logbook, including date, time, and tester’s name.
Why it matters:
This confirms the system can raise an alarm throughout the building — and it keeps staff familiar with the sound of the alarm.
If you manage multiple sites across Surrey, stagger tests so they don’t all happen at the same time — this helps avoid confusion with false alarms.
ESI Tip:
Pick a consistent time each week, e.g. every Tuesday at 10 a.m., and let your staff know. Consistency helps build a routine and ensures tests aren’t missed.
🔹 Quarterly Fire Alarm Servicing
Every 3 months, your fire alarm system should be professionally inspected by a competent engineer — usually a third-party certified fire alarm contractor.
What the engineer does:
- Checks all call points, detectors, sounders, and control panel functions.
- Tests standby power supplies (batteries).
- Reviews any logged faults and rectifies them.
- Confirms correct audibility levels and visual alert operation.
Why it matters:
This ensures the system’s integrity between full annual services and catches early signs of failure before they become dangerous.
Many Surrey Fire & Rescue enforcement notices are issued because quarterly tests were skipped — particularly in multi-tenant office buildings and HMOs.
🔹 Annual Fire Alarm Servicing
Once a year, your entire system must undergo a comprehensive service and inspection in line with BS 5839-1.
This includes:
- Testing every device (detectors, call points, sounders).
- Verifying circuits and wiring integrity.
- Cleaning and calibrating detectors to remove dust build-up.
- Testing batteries under load.
- Checking interface connections (e.g. door release, lifts, HVAC).
- Issuing a service certificate for your records.
This inspection must be carried out by a competent, qualified fire alarm engineer — not a general electrician.
Keep the service certificate with your fire safety documentation. You’ll need it for:
- Insurance renewals
- Fire officer inspections
- ISO or BAFE audits
ESI Tip:
If your system is large (multiple zones or devices), consider alternating between two service engineers to catch potential oversights.
🔹 Additional Checks
Depending on your system, you may also need:
- Monthly battery voltage checks (if not self-monitoring).
- Monitoring connection tests (if your system is linked to a remote alarm centre).
- Detector sensitivity testing — every 2 years for smoke detectors.
Your maintenance contractor should advise which apply.
The Fire Logbook — Your Best Friend in an Inspection
Surrey Fire & Rescue officers nearly always start an inspection with one question:
“Can I see your fire logbook?”
This document records all your tests, maintenance, servicing, and faults.
Your logbook should include:
✅ Weekly tests (which call point, date, and initials).
✅ Quarterly and annual service records.
✅ Notes of any faults, actions taken, and rectifications.
✅ Certificates from your fire alarm contractor.
If you can’t produce this, inspectors may assume you’re not maintaining your system properly — even if your alarms work fine.
You can download a free fire safety logbook template from the GOV.UK Fire Safety Guidance Collection.
Common Mistakes Found in Surrey Premises
From our 20+ years at ESI: Electrical and Fire Safety Specialists, these are the fire alarm mistakes we see most often in local businesses:
🚫 Skipped weekly tests because “the alarm always works.”
🚫 Missed quarterly services (especially during staff turnover).
🚫 Untrained staff silencing alarms incorrectly.
🚫 No maintenance contract or expired service certificates.
🚫 Control panels with fault lights ignored for months.
All of these can lead to enforcement action — or worse, a system that fails when it’s needed most.
How Often Should You Replace Your Fire Alarm System?
Most systems have a 10–15 year lifespan, depending on environment and maintenance quality.
You may need an upgrade sooner if:
- You’ve had frequent faults or false alarms.
- Spare parts are obsolete.
- Your building layout or use has changed.
- Standards or risk assessments recommend improvement.
A Fire Risk Assessment will identify whether your system still meets the required standard.
The Surrey Fire & Rescue Perspective
Local fire officers don’t expect perfection — but they do expect proactive management.
If you can show:
- A current Fire Risk Assessment,
- A valid maintenance certificate, and
- A complete logbook,
You’ll demonstrate that you’re taking fire safety seriously — and that goes a long way during inspections.
