Fire Door Installation

Who can legally install a fire door?

There is no statutory licence, card or mandatory qualification for fitting a fire door in the UK — unlike gas work or notifiable electrical work. Anyone can, in principle, hang a fire door. What the law actually requires is competence, and that duty sits in more than one place at once, so it is not optional in practice.

In England, Regulation 11F of the Building Regulations 2010 — introduced following the Building Safety Act 2022 — requires any individual carrying out building work to have "the skills, knowledge, experience and behaviours" necessary for it. Fitting a fire door the Building Regulations require is building work, so the duty applies directly. Once a building is occupied, government guidance under the Fire Safety (England) Regulations 2022 is explicit that fire door repairs and replacements must be carried out by a competent contractor.

The recognised way to evidence that competence is third-party installer certification. Two UK schemes dominate: FIRAS (operated by Warringtonfire and UKAS-accredited) and BM TRADA Q-Mark Fire Door Installation. Both audit companies — office systems, site workmanship and staff competence — rather than issuing personal licences. For the full picture, see our guides to who can install fire doors and fire door certification schemes.

What does compliant fire door installation involve, step by step?

A fire door is tested and certified as a complete assembly — leaf, frame, seals, glazing and ironmongery working together. Compliant installation is the discipline of reproducing that tested configuration in a real structural opening, and then evidencing that you did. When we open in 2026, our supply-and-fit process will run through the stages below, each one producing a record that feeds the building's fire safety information.

The heart of the job is stage 3. BS 8214:2016 is the code of practice for installing timber-based fire doorsets, and it governs the details that decide whether the door performs: frame fixings correctly spaced and penetrated into the supporting construction, frame-to-wall voids packed with the right material, perimeter gap tolerances held to the certificate (typically 2–4 mm at head and jambs), and an intumescent perimeter seal and ironmongery matched to the tested design — not the nearest substitute.

What's included, and what does good look like?

"Fitting a fire door" is scoped very differently by different contractors, which is why quotes vary so widely. Our supply-and-fit service is designed around the compliant version — the doorset, the installation and the evidence, not just the labour of hanging a leaf. When we open, a standard installation will include:

• Laser survey of each structural opening and confirmation of the correct doorset specification before anything is ordered.
• A complete certified doorset — leaf, frame, seals, glazing and ironmongery supplied as one unit under a third-party scheme (see our fire doorsets), rather than a leaf hung in a mismatched frame.
• Installation to BS 8214 and the manufacturer's instructions, including packing frame voids, setting perimeter gaps and fitting the intumescent seal and self-closer.
• Matched, certified ironmongery — hinges, closer, locks and latches from within the doorset's certification scope, not swapped for uncertified alternatives.
• Photographic gap and fixing records and a per-door completion checklist.
• A Regulation 38 handover pack and golden-thread-ready records for the responsible person.
• Making good and waste removal so the opening is left complete, not part-finished.

What "good" looks like on a finished door

A correctly installed doorset has even perimeter gaps within the certified tolerance; a continuous, undamaged intumescent seal; a frame packed and fixed so it does not move; a self-closer that closes the door fully from any angle onto an engaged latch; and ironmongery that matches the certificate. Crucially, it comes with paperwork identifying the exact doorset, its certification and how it was fitted — because a door you cannot evidence is a door you cannot prove is compliant. Our fire door inspection service checks exactly these points on doors already in service.

Why does installing to the tested specification matter?

This is the single most important point on the page: a certified fire doorset only performs as tested if it is installed to its tested configuration. Certification proves the product was tested and manufactured under audit — it says nothing about the person fitting it or the opening it goes into. An FD30 doorset that carries a valid certificate but is hung with oversized gaps, unpacked frame voids, missing intumescent protection or a substituted closer is not a compliant fire door, however good its certificate looks.

The failure mode is invisible. A poorly fitted fire door looks identical to a well-fitted one until there is a fire, at which point the difference is measured in minutes of protection lost. This is why the industry treats installation as "life critical as the product specification itself", and why the distinction between a tested doorset and a site-assembled door assembly matters so much: the doorset removes the compatibility guesswork, but only correct installation preserves it.

What will our fire door installation service offer when we open in 2026?

We are honest about where we are: pre-launch, opening in 2026, with no completed projects, no accreditation numbers and no reviews yet. What we can describe is what the service is being built to deliver. When it goes live, it will be a UK-wide supply-and-fit service for certified fire doorsets — from single flat entrance doors to whole blocks and commercial refurbishment programmes — with the evidence trail built in from survey to handover.

• UK-wide coverage — we intend to work across England, Wales, Scotland and Northern Ireland, applying the fire door standard relevant to each nation's building regulations.
• Supply and fit as one accountable package — the same business surveys, supplies the certified doorset and installs it, so responsibility for the tested configuration is not split across parties.
• Evidence-led handover — photographic records, a Regulation 38 pack and golden-thread-ready documentation with every installation.
• Programme capability — flat entrance door replacement programmes for blocks over 11 metres, where recurring checks apply, are a core focus.
• Certification published on grant — the day our FIRAS / Q-Mark installer certification is granted, the scheme, scope and number will appear on this page.

For buildings that fall under the Building Safety Act, the installation records we produce are designed to slot straight into the golden thread. For blocks in England over 11 metres, the same records support the responsible person's ongoing duty under regulation 10 of the Fire Safety (England) Regulations 2022 — communal fire doors checked at least every three months, and best endeavours to check flat entrance doors at least every twelve months. If that is your building, register your interest now and we will make contact as the service opens.

What does fire door installation cost?

We are pre-launch and do not publish our own prices yet — so the figures here are typical UK market ranges from independent 2026 cost guides, not quotes from us. Published guides put compliant supply-and-fit for an internal FD30 door at roughly £300–£600 per door, with higher-specification, glazed or entrance doors at £600–£1,200+, and composite flat entrance doorsets higher again once installation and making-good are included. The full sourced breakdown, with the origin and year of every figure, is in our fire door cost guide.

The wide spread is almost entirely about scope. The cheapest quotes usually assume the existing frame is reused, no making-good is needed and no certification evidence is supplied — not the same product as a certified doorset installed to BS 8214 with a handover pack. So compare deliverables, not just totals: is it a certified doorset, is the frame included, are gaps and firestopping signed off, and what documentation arrives at handover? Silence on any of those is a price signal, not a saving.
