Quick answer

Fire door installation is certificated work in all but law: FIRAS and BM TRADA installer schemes audit fitting competence the way BAFE audits alarm firms — and post-Grenfell procurement increasingly requires them. Verify scheme membership and scope, demand per-door documentation (photos, gap records, certificates), and treat 'any carpenter can hang it' as the red flag it is.

The schemes and what they audit

  • FIRAS (installer certification): audited fire door installation competence — site inspections, documentation standards, workmanship sampling; the scheme name procurement frameworks cite
  • BM TRADA Q-Mark installer scheme: parallel audited certification, doorset-aligned (pairs naturally with Q-Mark doorset products — chain-of-custody logic)
  • What audits cover: gap-setting discipline (the 3mm religion), seal and hardware fitting per certification, frame works, documentation habits — the difference between fitted and evidenced
  • Adjacent competence: fire-stopping around frames (the wall-to-frame junction is a compartmentation joint — the fire-stopping guide's territory meeting joinery), and survey literacy (condition grading per the inspection discipline)
  • The law's shape: no licence exists, but the Fire Safety Order's competence expectations, building-control scrutiny and (for blocks) golden-thread documentation make scheme certification the practical standard — the who-can-install logic from fire alarms, doored

Red flags and the questions that sort installers

Walk-away signals: 'fire door's just a heavy door' energy (the assembly-not-leaf principle absent), no scheme membership and no documentation offer (photos? certificates? gap records? — blank looks), merchant-leaf-into-existing-frame defaults (the cost guide's third route to non-compliance), furniture improvisation (van-stock hinges and unrated letterplates — the modification rules unread), and price-led scope silence (frame condition unaddressed, making-good unmentioned). Sorting questions that work: 'which scheme are you certificated under, and can I see a recent audit?'; 'what documentation do I receive per door?'; 'how do you handle a frame that turns out rotten?'; 'what gap tolerances do you set and record?' — fluent answers pattern-match to the inspection guides' content; hesitation patterns to future remedial invoices.

Procurement structure for door projects

Process echoing our quote-comparison playbooks: like-for-like briefs (door schedule with conditions noted, certification route required — doorset or certificated assembly, documentation deliverables named), 2–3 scheme-verified bidders, references in your building type (blocks' liaison demands differ from school summers — the programme guides' realities), and contractual documentation hooks (per-door evidence as a payment condition, not a courtesy). Weight the survey quality heavily: installers whose quotes grade each door (repair/replace/upgrade per the remedials economics) demonstrate the competence the schemes certify; flat-rate-per-door quotes across ungraded stock demonstrate optimism. Our installation and remedial services run FIRAS-aligned with the documentation packs as standard — and the verification invitation stands here as everywhere: check schemes, check references, make every bidder pass the same gate.

Frequently Asked Questions

Is FIRAS legally required to fit fire doors?
No statute names it — but competence requirements, procurement frameworks and insurer/building-control expectations converge on scheme certification as the evidence standard (the fire-alarm installer logic exactly). Unverifiable competence is the liability you keep.
Can our maintenance carpenter do fire door remedials?
Simple closer swaps and seal replacements with the right components and records: defensibly, if competent. Gap corrections, glazing, anything touching certification scope: scheme-certificated work (the remedials guide grades the tasks).
What documentation should installation leave behind?
Per door: installation certificate, doorset/product certification, photographic record, gap measurements, hardware schedule — filed to the building's fire safety records (golden thread for blocks). No documents, no evidence, no defence.
Do you survey before quoting door works?
Always — door-by-door condition grading drives honest scopes (repair-vs-replace per the economics guides). Quotes without surveys are guesses; ours come with the evidence attached.
