If you've just appointed a new fire alarm contractor to look after a building you're responsible for, their very first visit shouldn't look like a routine service. Before they can start signing off six-monthly maintenance certificates, BS 5839-1:2025 requires them to carry out a special inspection: a full audit of the system they've just inherited, not just a quick look round. If your new contractor's first visit looked and felt identical to every visit after it, that's worth asking them about.
Where this comes from
Clause 44.1 of BS 5839-1:2025, headed "Special inspection on appointment of a new servicing organization," sets out what has to happen when a servicing contractor takes over maintenance of a system they didn't originally install or service. In practice, that's most new clients. A building's fire alarm system is very rarely brand new the moment a new contractor picks it up, and the standard treats that handover moment as a real compliance checkpoint, not an administrative formality.
The logic is straightforward. A new contractor has no history with the system. They don't know what's been fixed, what's been ignored, or what's quietly drifted out of spec since it was installed. Clause 44.1 exists to make them find out, and write it down, before they put their name to any future certificate for that system.
What it actually establishes
Under 44.1.1, the incoming contractor has to review whatever existing records they can get hold of, starting with whether a system log book even exists and where it's kept. If there isn't one, 44.1.3 requires a new one to be issued as part of this same visit. A system with no log book, no as-fitted drawings and no history of previous defects is not unusual for a client changing providers, and it's precisely the situation this clause is designed to catch and correct.
From there, the special inspection goes well beyond a records check. It's closer to what a surveyor would call a full asset survey and dilapidation report than a service visit: done once, thoroughly, before routine maintenance begins.
What actually gets audited
A proper special inspection covers the whole system, section by section:
| Covers | What's checked |
|---|---|
| Panel & asset record | Every control and repeater panel: make, model, age, protocol, software version, loop/circuit capacity in use vs. available, mains isolation, zone plan, and full standby battery details. |
| Device inventory | A full count of every detector, call point, sounder and interface device on the system, by type. This is the baseline every future visit gets measured against. |
| Category & coverage | What detection category the system is actually designed to (L1–L5, P1/P2, M) and whether real coverage on the ground supports that, including call-point spacing against Clause 19's 45m maximum travel distance. |
| Cabling | Fire-resistant cable used, correctly segregated and mechanically supported per Clause 25 and Clause 27, not just cable ties holding a containment run together. |
| Monitoring, power & sound | Fault monitoring, standby power supply calculated against Annex E, and audibility checked against Clause 15's sound-pressure thresholds throughout the building, including bedhead levels where relevant. |
| Log book & history | False alarm history assessed against the real Annex F thresholds, drawings and original design/commissioning certificates checked for availability, and any known variations from the original design recorded. |
| General condition | An honest overall rating: Excellent, Good, Operational, or Non-Operational. A Non-Operational finding here is treated with the same urgency as a Category 1 defect, so it doesn't wait for a follow-up visit to be flagged. |
| Remote monitoring | Whether the system reports to an Alarm Receiving Centre, and if so, exactly how: provider, contract number, signalling method. |
The whole thing is signed off by the engineer, just like any other certificate. What they're certifying is different, though. This isn't "the system was tested and works." It's "this is the true, documented state of what we've taken responsibility for."
Why this actually matters to you
As the responsible person, you carry personal legal liability under the Fire Safety Order 2005 for the building the system protects, regardless of who happens to be maintaining it this year. If your previous contractor left gaps (a missing zone plan, cable runs that were never properly segregated, a false alarm rate nobody investigated) those gaps don't disappear when you change providers. They become your new contractor's problem to find, and your problem to know about.
A properly done special inspection means you get a real, documented baseline the moment a new contractor takes over, not a slow discovery of "surprise" defects drip-fed to you over their first year on site. It's the clearest moment you'll ever get to see exactly what you actually own.
How FireCompliance Pro handles this
The platform tracks whether a client's special inspection has been completed as a real, structured fact, not a note in someone's inbox. The first time a job is created for a new client with an existing system, the engineer's visit form surfaces the full Clause 44.1 checklist automatically. Routine maintenance can't proceed as if it were any other visit until it's done, and sign-off marks it complete, permanently, against that client.
Because the special inspection and the routine six-monthly service happen in the same visit, you get both documents at once: the special inspection report and a standard servicing certificate, landing straight in your client portal rather than chased over email months apart. Every finding, every category assessment, every flagged non-compliance is there in your own record, searchable against the site it belongs to, for as long as you hold the building.
Whether you're onboarding a new client's system for the first time or reviewing one a contractor completed years ago, FireCompliance Pro keeps the special inspection as a permanent, queryable part of that building's compliance history, not a PDF that gets lost in an inbox.
