Fire Alarm Servicing ![Ceiling smoke detector being tested with a service pole during a fire alarm service](/assets/img-08-Df11UZFX.jpeg) [South Wales & Bristol](/) # Six-Monthly Fire Alarm Servicing & Certification Scheduled, documented servicing that keeps your system compliant, your insurer satisfied and your licence intact, delivered on-the-date, every date, with the certificate emailed before our van leaves your kerb. [Request an Estimate](/contact-us) [07360 538643](tel:07360538643) Trusted by landlords, developers & letting agents across South Wales & Bristol. 15+ Years on the tools BS 5839 Certified to standard 24–48h Typical callout window 100% Insured & DBS-checked Service overview ## Fire Alarm Servicing, explained without the jargon ### What it is A BS 5839 inspection and test of every device, sounder, panel battery and cause-and-effect routine on your fire alarm system, carried out at six-monthly intervals by a qualified engineer. ### Who it's for HMO landlords with active licences, letting agents managing third-party portfolios, commercial occupiers, schools, care providers and anywhere the Responsible Person under the RRFSO needs an audit trail. ### When it's needed BS 5839-1 (commercial) requires service visits at intervals not exceeding six months. BS 5839-6 (domestic/HMO) recommends annual professional servicing plus weekly user tests, most licensing schemes require six-monthly. ### Why professional matters Without dated, signed service records your fire alarm is technically non-compliant the moment the previous certificate expires. Insurers will use the gap to repudiate a claim. The cost of ignoring it ## What happens when servicing slips ### Risks if left unchecked - ● Licence enforcement action and immediate prohibition notices from local fire authorities. - ● Insurance cover void on the date the last certificate expired, not the date of the incident. - ● Battery failures during a real activation, the system simply does not sound. - ● Detector contamination that silently raises false-alarm rates and trains occupants to ignore the bells. ### Common mistakes - ● Relying on the alarm company's reminder email, there isn't always one. - ● Letting a non-competent handyman 'test' the alarm by pressing a single call point. - ● Skipping a service after a panel was replaced, breaking the certificate chain. - ● Storing certificates in a desk drawer instead of a digital, dated log accessible to inspectors. An expired servicing record is the first thing a fire safety officer asks for after an incident. There is no retrospective fix, the date is on the certificate. Our process ## A clear path from enquiry to certificate 1. Step 1 ### Schedule We diary your next two service dates at handover. You get a calendar invite and a 7-day reminder, no nagging, no missed slots. 2. Step 2 ### Pre-visit checks Engineer reviews the previous report and any logged faults so the visit fixes problems rather than just documenting them. 3. Step 3 ### On-site test 100% device test on a six-monthly rotation, panel battery load test, sounder dB readings, cause-and-effect verification and visual condition check. 4. Step 4 ### Faults & quote Any minor faults rectified on the spot; larger items quoted in writing the same day so you can decide before we leave. 5. Step 5 ### Certificate & log update BS 5839 service certificate issued digitally, your site log book signed and a copy filed to your portal, ready for inspection. Why clients stay with us ## Specific, measurable benefits ### Compliance, on time We diary the dates and turn up. You don't need to chase. ### Fewer false alarms Detector cleaning and zone management cuts unwanted activations and stops occupants ignoring bells. ### Insurance protection An unbroken certificate chain that your insurer can verify on demand. ### Lower long-term cost Catching a failing battery at a planned service is far cheaper than catching it after an emergency callout. ### Single portal All your properties, all certificates, one login, useful for portfolios and letting agents. ### Honest reporting We list every device tested. No 'sampled and assumed compliant' shortcuts. Technical detail ## Everything that goes into a proper fire alarm servicing A fire alarm service visit is a technical inspection governed by section 45 of BS 5839-1 and section 25 of BS 5839-6. Below is what we actually do, and what some lower-priced providers quietly skip. ### What a compliant six-monthly visit includes Visual inspection of panel, batteries, devices and cabling; functional test of at least 25% of automatic detectors each visit (100% over the year); test of every manual call point annually; sounder dB readings in sleeping areas; standby battery load test; cause-and-effect verification for any interfaces (door holders, AOVs, lift recall). ### What we do that others skip Detector head removal and contamination check, panel firmware version log, battery serial and date recording, and full-loop quiescent current measurement. These add 20 minutes and they are the difference between a service and a sticker. ### Servicing wireless and hybrid systems Wireless detectors carry their own 5-year sealed batteries, we record install date and forecast replacement at the next-but-one service so it is never a surprise cost. ### Multi-site servicing for portfolios Letting agents and landlords with 5+ properties get a single quarterly schedule, consolidated invoicing, and a portal listing certificate dates so you can prove compliance across the portfolio in one screen. ### Taking over from another provider We never charge to take over, a free takeover inspection lists any compliance gaps in writing, and we quote remediation separately before adopting the contract. ### Out-of-hours and emergency cover Contract clients get a priority phone line with a rapid response for total system failures and a 48-hour SLA for partial faults.
