Quick answer

Fire alarm maintenance runs £200–£400/year for small systems, £400–£900 for medium commercial, four-figure for large estates — covering the twice-yearly servicing BS 5839-1 recommends, certificates after each visit, and callout terms. Unlike security alarms, this isn't optional in practice: unserviced fire systems void insurance positions and breach the Fire Safety Order's maintenance duty.

What the 6-monthly visits must actually cover

  • Functional testing of a rotating proportion of devices so every detector/call point proves over the cycle (100% annually is the working norm)
  • Panel health: batteries load-tested, charger checked, fault log reviewed and chased
  • Sounder coverage spot-verified; visual alarm devices checked
  • Cause-and-effect sampled: door releases, AOV triggers, interfaces actually operated, not assumed
  • False alarm review against the log — with detector relocation/type recommendations where patterns show
  • Battery replacements scheduled (panel ~4-yearly, wireless device rounds)
  • Certificate of inspection/servicing issued each visit + log book entries — the documents your insurer and fire officer ask for by name

Fair pricing and what moves it

The honest bands: small conventional (shop/HMO panel): £200–£400/yr over two visits; single-loop addressable office: £300–£500; medium commercial (schools, care, multi-floor): £400–£900; networked estates: priced per panel/device count. Movers: device count (testing time scales), site access hours (out-of-hours servicing for care/retail), interface complexity, travel, and whether emergency callout response (4-hour SLAs etc.) is included or per-incident. Watch the structural trick of underpriced contracts recouped via mandatory call-out charging and parts mark-ups — per-visit pricing with parts at list, disclosed, compares cleaner than 'all-in' mysteries.

Contract terms that matter when it matters

Read for: response time to faults in hours with out-of-hours reality (a fire panel in fault is an insurance exposure every night it persists); parts inclusion tiers; emergency attendance pricing; engineer competence/third-party certification of the firm (BAFE SP203 maintenance scope or equivalent); takeover terms (most contracts start by inheriting someone else's system — a documented initial condition survey protects both sides); and exit/renewal honesty (rolling annual beats long lock-ins; auto-renewal windows noted in your calendar). Multi-discipline bundling is the quiet saver: fire alarm + emergency lighting + extinguishers + (our combined offer) security systems on one schedule cuts windscreen time you'd otherwise fund — the compliance packages page shows that model.

Frequently Asked Questions

Is 6-monthly servicing legally required?
BS 5839-1 recommends it and the Fire Safety Order requires maintenance 'in efficient working order' — in enforcement and claims, the 6-monthly certificated regime is the evidence standard. Annual-only servicing of commercial systems is a gap inspectors notice.
Can we test the system ourselves between services?
You must: the weekly call point test (rotating) and log are the user side of BS 5839-1 — see the weekly test how-to. It complements, never replaces, competent servicing.
What if the maintainer finds defects?
You get them in writing with remedial quotes — and the duty to act lands on the responsible person. Sitting on defect reports is how prosecutions start; phased remedial plans are how budgets cope.
Can you take over maintenance mid-life?
Routinely: condition survey, certificate to current state, contract forward — open-protocol systems (MxPro, C-Tec, Kentec) make this clean. We're straight about closed systems before you sign anything.
