Certifire Fire Doors: What Certifire Certification Means (and How to Check It)

If a fire door specification names one certification scheme, it is usually Certifire — often written as "Certifire or equivalent". Run by Warringtonfire, Certifire is the most widely specified third-party certification scheme for fire doors and passive fire protection products in the UK. But a Certifire logo on a brochure is not the same as a certified door in your frame. This guide explains what Certifire certification actually covers, how the BWF-Certifire scheme relates to it, and how to check that the CF number on a door label is genuine. For how Certifire sits alongside the other UK schemes, see our fire door certification hub and the full certification schemes guide.

What is Certifire?

Certifire is a third-party product certification scheme operated by Warringtonfire from its UKAS-accredited Warrington office. Third-party certification goes further than a one-off fire test: as well as initial type testing to BS 476-22 or BS EN 1634-1, the manufacturer's factory production controls are audited on an ongoing basis, so every door leaving the line should match the specification that passed the furnace. Each certified product is issued a Certificate of Approval with a CF number — for example CF271 — which records exactly what was tested: leaf constructions, sizes, glazing options, intumescent seals and the ironmongery the door may be fitted with.

What a Certifire certificate covers

A Certifire certificate is a technical document, not a badge. It defines the certified doorset or door leaf, its fire rating (FD30, FD60 and above), the permitted size envelope, and the components — hinges, closers, locks, seals and glazing systems — it has been proven to work with. This matters in practice: a certified FD30 leaf hung on non-approved hinges, or trimmed beyond the certificate's tolerances, is no longer the assembly that was tested. Certifire also certifies the components themselves, which is why specifiers often look for certificated seals and ironmongery as well as the leaf.

Certifire and BWF-Certifire: what's the difference?

BWF-Certifire — today operating as the BWF Fire Door Alliance — is the British Woodworking Federation's scheme for timber fire doors, built on Certifire certification. Member manufacturers' doors carry Certifire certificates plus the Alliance's colour-coded plugs and labels, and the Alliance publishes widely used best-practice guidance on installation, maintenance and keeping certification intact. In short: Certifire is the certification engine; BWF Fire Door Alliance is the timber industry scheme wrapped around it.

How to verify a Certifire fire door

Look for the label or plug on the top or hinge edge of the leaf. It should carry the manufacturer, the fire rating and the CF certificate number. That number can be checked against Warringtonfire's public Certifire product register, and the Certificate of Approval — with its permitted sizes, glazing and ironmongery — can be downloaded or requested from the supplier. Keep it with your building's fire safety records: inspectors, insurers and Building Control will ask for it, and fire door inspections are far simpler when the paperwork matches the door. Treat any door without a verifiable certificate as uncertified, whatever the sales listing claims — and note that certification also depends on correct installation, which is why the certificate's fitting instructions take precedence over general guidance.

Certifire and BM TRADA Q-Mark are equally respected — most specifications accept either. Every door we supply comes with its third-party certification evidence, so if you need the certificate before ordering, browse our certified FD30 fire doors or ask us and we will share the documents for the exact door you are buying.
