How Often Should a Commercial Fire Alarm Be Tested and Serviced?
Making sure your fire alarm works properly is required by law. But how often should you test it? Who should do it? What kinds of checks are needed? This article breaks all that down clearly, with references to the current law, standard practices, and what you should actually put into your maintenance schedule.
| In summary: Know your legal duty under the Regulatory Reform (Fire Safety) Order 2005: your fire alarm must be maintained, tested, and kept in working order. Follow BS 5839‑1:2017 for non‑domestic premises: weekly tests, six‑monthly inspections, and annual full‑system checks are recommended best practice. Tailor your schedule based on your building’s size, use, risk, and occupancy. Higher risk means more frequent checks. Have staff do the simple checks (weekly, daily visual), use a contractor for more in‑depth inspections. Always keep records and a fire alarm logbook of all tests, failures, repairs. Use your fire risk assessment as the guide, and review it regularly (or when something changes, like building works or occupancy). |
What the Law Requires
The key law you need to know about is the Regulatory Reform (Fire Safety) Order 2005 (“Fire Safety Order”), which applies to most non‑domestic premises in England and Wales. Under Article 17 of that Order, the Responsible Person must ensure that “fire safety measures … are subject to appropriate maintenance” and are “kept in efficient working order” and good repair.
So the law doesn’t list specific intervals like “test every week, service every 6 months” in statute. It expects that your fire alarm system is maintained regularly and properly, and that you follow recognized good practice, which is where British Standards come in. These standards fill in the practical details.
The Fire Safety Order also requires that your checks and maintenance are carried out by competent persons; that faults are fixed; that systems are suitable for the building (size, usage, risk). The fire risk assessment you must carry out helps decide exactly what “suitable” means for your building.
What the British Standard BS 5839‑1:2017 Says
For commercial premises, the most relevant standard is BS 5839‑1:2017 (“Fire detection and fire alarm systems for buildings – Part 1”). This standard lays out detailed advice on how to test, service, maintain, and inspect fire alarms in non‑domestic settings.
Here are some of its key points:
- You should do weekly tests of a different manual call point (a “push‑glass” or “break‑glass” alarm actuation point) each week, rotating through all call points over time. That means each manual point gets tested periodically.
- You should carry out inspections and servicing by a competent person at least every six months. This is to check all the components (detectors, panels, sounders, wiring, batteries) are working properly.
- A full review or test (often called an annual test or full system check) is usually done once a year. In this test, the system is exercised under more demanding conditions (often including simulating faults or ensuring backup power works for the required period).

How Often Different Checks Should Happen
Putting the law + standards into practice means you’ll want a schedule of checks. How often depends on your building’s size, usage, risk, how many call points, whether staff are present at all times, etc. Below is a table summarising what many commercial premises do (or should do) to stay safe and compliant.
| Type of Check | Who Usually Does It | Typical Frequency | What Gets Checked / What’s Tested |
| Visual / Panel‑indicator check | On‑site staff, e.g. Facilities / Duty Person | Daily or at least every day the premises are operational | Look at the fire alarm control panel: are there any indicators, fault lights, warning messages, power supply status, battery faults, etc. |
| Manual Call Point test | Designated staff | Weekly | Activate a different manual call point each week; check alarm sounders, control panel response; reset system after test. |
| Sounder / Alarm functionality (quick test) | Staff or competent person | Monthly or as part of weekly tests | Ensure all alarm sounders/hooters work, particularly in far ends of the building; check volume, clarity. Maybe test backup or battery supply. |
| Professional inspection / servicing | Competent fire alarm contractor | Every 6 months | Technician checks detectors (smoke, heat), wiring, control units, power supplies & batteries; clean & replace parts as needed; ensure compliance with manufacturer specs. |
| Full system test (including duration & backup) | Contractor / fire safety specialist | Annually | Simulate faults; test battery or standby power for required time; test all zones; test or inspect all devices including detectors; full audit of system performance. |
| Extra checks after changes or incidents | Contractor / in‑house competent person | As soon as possible after layout changes, renovations, false alarm, or any event that might affect the system | Ensure call points still accessible, wiring not damaged, detectors not obstructed, alarm zones still correct, emergency response connections still functioning. |
What “Competent Person” Means
When the law says work must be done by a competent person, it means someone with the right training, experience, tools, and understanding to inspect, test, maintain or repair fire alarm systems safely and correctly. It could be a certified contractor or someone employed by the organisation who has special training. The important thing is that you can show the person is capable.
Also, you must keep records of all tests, inspections, repairs, etc., in a fire safety logbook (physical or digital). These records are often asked for if there’s a fire safety audit or inspection by authorities. If you can’t prove regular testing or repairs, that in itself can be a legal failing.
Is Weekly Testing Legally Required?
You’ll often hear that fire alarms in commercial premises must be tested every week. According to BS 5839‑1, this is best practice and strongly recommended. Weekly testing of manual call points is almost always expected.
However, statutory law (the Fire Safety Order) doesn’t explicitly say “weekly.” Instead it says “adequate maintenance.” But because BS 5839 is widely accepted and often used in audits, inspections, and court cases, applying weekly tests is the safest way to meet legal duty. If you don’t, you’ll need to justify your different schedule via your fire risk assessment (for instance, if you have fewer call points, fewer people, low risk, etc.).
Higher Risk Premises May Need More Frequent Testing
Some commercial settings have more risk (for example, hospitals, hotels, factories, large warehouses, care homes). If you’re in one of these, your fire alarm system may need more frequent checks than the base schedule.
Things that increase risk include:
- More people present (especially at night or continuously)
- Irregular usage patterns (e.g. shifts)
- Harsh environment (dust, heat, moisture) affecting detectors and wiring
- Multiple alarm zones or complex systems
- Legal/regulatory obligations (for instance in healthcare, where lives depend directly on immediate detection)
Riskier premises may choose or may be required (via risk assessment or insurer requirements) to do quarterly inspections, or more frequent detailed tests. Sometimes even monthly professional inspections might be justified.
Consequences of Not Testing or Servicing Properly
If a commercial fire alarm system goes untested or isn’t serviced regularly, the risks are serious:
- Someone could be injured or killed if the alarm doesn’t activate in an emergency.
- Legal consequences: under the Fire Safety Order, failure to maintain safety equipment can lead to enforcement notices, prohibition notices, prosecution, and fines. Responsible Persons are legally accountable.
- Insurance problems: insurers often require evidence of regular testing and servicing. If a claim arises after a fire, and you can’t show you followed best practice, you may have your claim reduced or refused.
- Higher repair costs: small faults caught early are far cheaper to fix than major failures.
- Reputational damage: safety failures can cause customer / staff distrust, business interruption, regulatory sanctions, or public exposure.

Sample Maintenance & Test Schedule for Commercial Premises
Here’s a practical schedule you can adapt to your building, staff, and risk level:
| Task | Do It Yourself / In‑House | Professional Contractor | When |
| Visual check of fire alarm control panel | Yes — front desk, facility manager, or staff | — | Every working day or start of day |
| Test a manual call point (rotated each week) | Yes — designated staff | — | Weekly |
| Monthly functional check of sounders and backup power / battery health | Staff or maintenance team | — | Monthly |
| Inspection & service of all detectors, wiring, panels | — | Contractor | Every six months |
| Full system test including battery backup & all zones | — | Contractor | Annually |
| Extra inspection after alterations, renovations, or faults | Staff or contractor depending on scale | Contractor | As soon as possible after change |

Fire Risk Assessment and Records
Your fire risk assessment (required under the Fire Safety Order) should specify how often the alarms should be tested and serviced in your building. It should take into account how big your building is, how many people use it, how often systems are already tested, and past faults. If your assessment shows you need extra checks, then do them; that assessment carries legal weight.
Keeping good records is essential. Logs of weekly tests, monthly checks, six‑monthly services, annual tests, plus any faults and remedial work, all should be stored. If ever you have a fire investigation or inspection, those records are your proof you met your duty.

FAQs
To help with some common confusions, here are questions people often search and their answers:
Can staff do the weekly tests, or does it have to be a contractor?
Staff can do weekly tests (e.g. activating a manual call point, checking sounders, resetting panel), provided they are trained and competent to do so. What matters is that the test is done properly, safely, and recorded. The more detailed servicing (six‑monthly and annual) should be done by a professional with experience in commercial fire alarm systems.
What exactly must be included in a “professional service”?
A proper professional service should include a thorough inspection of all detectors (smoke, heat), manual call points, wiring connections, sounders and bells, control panel, standby and backup power (batteries or generator), checking for corrosion, damage or blockage, cleaning components, ensuring system meets the original performance specs and manufacturer guidance.
Is there ever a case where you can do less than weekly tests?
In theory yes, but only if your fire risk assessment justifies it. If your premises are very small, with limited manual call points, always staffed, low risk, you might argue fewer weekly tests. But because BS 5839‑1 is widely accepted and frequently used in audits, using anything substantially less without a strong reason is risky.
What happens if tests fail?
If a test fails (a call point doesn’t work, sounders are quiet, panel shows faults), you must treat it as urgent. The fault must be repaired by a competent person, re‑tested, and documented.
Are there extra requirements for higher risk buildings like hospitals, care homes or hotels?
Yes. Buildings with more occupants, more vulnerable people, continuous occupancy (e.g. care homes), or activities that increase the fire risk (e.g. kitchens, storage, manufacturing) often require more frequent inspections or servicing, possibly extra zones or more manual call points. Your fire risk assessment should determine that.
