By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
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.
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.
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.
We install and maintain fire and security systems across Bedfordshire, Hertfordshire and London — with fixed written quotes, a 36-month warranty, and certification your insurer will accept.
