Quick answer

Servicing quotes compare on five axes: visit frequency (6-monthly is the BS 5839-1 standard), testing scope (100% of devices annually via rotation — ask the percentage), callout terms (response hours, included or chargeable), parts/batteries policy, and certification deliverables per visit. Cheap quotes usually hide in scope: 50% annual testing and premium-rate callouts reverse the saving.

The five comparison axes in detail

  • Frequency: twice yearly per BS 5839-1's recommendation — annual-only quotes are a different (lesser) product for commercial premises; some risk classes (care) warrant quarterly attention
  • Testing percentage: every device functionally tested across the year (50%/visit rotation) is the standard — quotes silent on percentage are answering a question you didn't ask; sub-100% annual cycles leave devices unproven for years
  • Callout terms: response time in hours (and the out-of-hours reality), included-vs-chargeable attendance, rates published — the line where lowball contracts recoup
  • Parts and batteries: panel batteries (~4-yearly), device batteries (wireless), head replacements — included, stocked-on-van, or quoted-and-deferred? Battery-excluded contracts generate the deferred-maintenance estates we inherit
  • Deliverables: BS 5839-1 inspection/servicing certificate each visit, log book completion, defect reports with quotes — paper is the product's proof (insurers and inspectors read it, per the maintenance guide)

Where cheap quotes actually save (their) money

The economy patterns, named: rotation theatre (testing 25%/visit = full proof every two years — meets nobody's standard); drive-by servicing (panel-only checks, devices untested — fast, certificated-looking, hollow); callout harvesting (£45/visit headline, £180/hour attendance for everything found); parts mark-up structures (batteries at 3× trade, head replacements 'requiring' return visits); and certificate-without-scope documents that read right until a fire officer asks what was actually tested. None are illegal; all are answerable by the five axes asked in writing. The takeover surveys we run behind departed cheap contracts find the same estate every time: aged batteries, untested wings, log books of rubber stamps — deferred cost wearing a saving's clothes.

Comparing fairly and switching cleanly

Get quotes against a stated scope (device count from your log book/asset register — or have bidders survey; guessing estates produce guessing prices), require the five axes explicitly, and weight whole-cost: visit fees + realistic callout exposure + parts policy across a 3-year view. Switching mechanics are easier than incumbents imply: certificates and log books are yours, takeover condition surveys (industry standard, ours included) baseline the estate honestly, and open-protocol systems (the panels guide's theme) transfer without drama — closed-protocol handcuffs are themselves a finding worth knowing. Bands for calibration: small conventional £200–£400/yr; single-loop addressable £300–£500; medium commercial £400–£900 — materially below those bands, re-read the axes; the gap is hiding somewhere you'll meet it later.

Frequently Asked Questions

Is annual-only servicing ever acceptable?
BS 5839-1 recommends 6-monthly for commercial systems; very small/simple premises sometimes argue annual via risk assessment — but insurers and inspectors expect the standard rhythm, and the price difference rarely justifies the exposure.
What should a servicing visit cost standalone?
Per-visit equivalents: £100–£250 small systems, £200–£450 medium — halves of the annual bands. Hourly-rate servicing without scope commitments isn't comparable; you're buying outcomes (tested estate, certificates), not hours.
Our quote says 'maintenance' — same as servicing?
Language varies; scope governs: inspection/test/certificate cycles (servicing) vs repair provisions (maintenance) vs both (comprehensive). Make the document define itself against the five axes — titles are marketing.
Can we hold a contract but use others for remedials?
Usually yes (check terms) — competitive remedial quoting keeps everyone honest, though single-accountability has operational value. What matters: defects quoted transparently enough to compare at all.
