How to Price Fire Door Installation: Labour, Materials and Margin Guide

Summary

Fire door pricing trips up tradespeople because a fire door is not a door — it is a certified system, and the certification only holds if every component and every gap is correct on the day it is signed off. A genuine FD30 or FD60 doorset is the leaf, the frame, the correct intumescent and (where needed) cold-smoke seals, fire-rated hinges, closers, locks and any glazing, all installed to BS 8214 with the right perimeter gaps and the right packing. Quote it as a loose leaf plus "some seals" and you have mispriced the job and potentially created a door that will fail an inspection and a fire.

The market splits into two very different jobs. The first is a one-off domestic fire door — a loft conversion, an integral garage door, a door onto a protected stairway in a house — where you fit a single certified set and make good. The second, and where most fire-door work and margin now sits, is communal and commercial replacement: flat entrance doors and corridor/stairwell doors in blocks of flats, schools, care homes and HMOs, driven hard since the Fire Safety (England) Regulations 2022 put fire-door inspection duties on responsible persons. That work is repetitive, volume-priced, and demands evidence — certification, photos, and a clear paper trail per door.

This guide gives realistic 2026 UK material and labour costs, labour hours per door, regional rates, the labour/materials split, the typical net margin, the red flags that change the price, what to itemise on a fire-door quote, and the pricing mistakes that quietly turn a profitable job into a liability. The golden rule: never break the certification to save money, and never imply a fire rating you cannot evidence.

Key Facts

• FD30 certified doorset (leaf + frame, supply only) — £250–£550 each depending on finish and glazing
• FD60 certified doorset (supply only) — £400–£900 each; heavier leaf, more hardware
• FD30 fire door leaf only (no frame) — £120–£300; cheaper but you must verify frame/seal compatibility
• Intumescent + cold-smoke seal set (per door) — £15–£45 supplied; the cheapest critical component
• Fire-rated hinges (set of 3, CE-marked) — £15–£40; minimum three hinges on a fire door
• Fire-rated overhead door closer — £35–£120; required on most communal fire doors
• Fire-rated lock/latch and intumescent pads — £20–£70 per door
• Fire-rated glazing (per vision panel, supplied) — £80–£250 depending on size and rating
• Labour per door (replacement, communal) — 2–4 hours per leaf in volume; 0.5–1 day for a one-off domestic set
• Day rate (carpenter/joiner) — £180–£280/day most regions; £280–£420/day London and South East
• Labour share — typically 30–45% of the installed cost; the doorset dominates materials
• Typical net margin — 20–35%; volume communal work runs leaner, one-offs richer
• Maximum leaf-to-frame gap — commonly 2–4mm consistent around the leaf
• Threshold gap — typically no more than 3mm to a non-combustible floor, or with a threshold seal
• Door tag / plug — most certified doors carry a colour-coded label or plug evidencing rating — never paint over or remove it
• VAT — 20% standard; reduced rate may apply on some qualifying conversions and certain residential works
• Inspection frequency (communal, England) — flat entrance doors annually, common-area doors quarterly under the 2022 Regs

Detailed Guidance

Labour time

For a one-off domestic fire door — say a new FD30 onto a loft stair or an integral garage — budget half a day to a full day. That covers surveying the opening, hanging the certified leaf in (or with) the correct frame, fitting three fire-rated hinges, the closer if required, the lock/latch with intumescent protection, the intumescent and smoke seals, checking every perimeter gap, and making good and decorating. FD60 sets are heavier and usually a two-person hang, pushing the time up.

Communal replacement work is priced per door in volume, and the per-door time falls sharply once you are set up on site. A straight leaf swap into a sound existing frame is roughly two to three hours; a full doorset replacement (frame and all) is three to five hours for FD30 and four to six for FD60. The hidden time is the evidence: photographing the door tag, the gaps, the seals and the finished install for the responsible person's records. On a 40-door block, that paperwork is real time — price it in. Always factor mobilisation, making-good and waste removal, which are easy to forget when you are quoting a clean per-door rate.

Materials & prices (2026 UK)

The certified doorset is the dominant cost. An FD30 doorset (leaf and compatible frame) is £250–£550 supply-only depending on finish, core and any glazing; FD60 is £400–£900. You can buy a leaf only from £120–£300, but only do so if you can evidence that the leaf, frame, seals and ironmongery together still hold the certification — mixing components from different systems can void the rating.

The supporting components are cheap relative to the doorset but non-negotiable: an intumescent and cold-smoke seal set is £15–£45 per door, a set of three CE-marked fire-rated hinges £15–£40, a fire-rated overhead closer £35–£120, and a fire-rated lock/latch with intumescent pads £20–£70. Fire-rated vision-panel glazing adds £80–£250 per panel supplied. None of these are places to cut — a £20 seal set is what stands between the door and a failed inspection. Quote the full ironmongery and seal schedule explicitly so the client sees you are pricing a certified system, not a bare leaf.

Regional rates

Fire-door work is priced either as a day rate plus materials for one-offs, or as a fixed per-door rate for volume communal contracts. Carpenter/joiner day rates run £180–£280/day across most of the UK and £280–£420/day in London and the South East. On volume communal work, going per-door installed rates are commonly £350–£750 for FD30 and £750–£1,400 for FD60, with London and the South East at the top of those bands and the North, Midlands, Wales and Scotland lower.

Volume sharpens the rate: a block of 40 flat-entrance doors lets you spread mobilisation, buy doorsets at trade volume and move quickly per opening, so your per-door price can sit well below a one-off. But do not let a keen per-door rate erode the evidence and making-good time — those costs are fixed per door regardless of volume.

Margin

A healthy net margin on fire-door work is 20–35%. One-off domestic installs sit at the upper end because the survey, fit and make-good carry real skill and the client is paying for certainty. Volume communal contracts run leaner per door (often 15–25%) because they are won competitively, but the total margin can be strong on a large block if your per-door time is tight.

Because the doorset dominates materials and labour is only 30–45% of the bill, your margin is more sensitive to material markup and procurement than on labour-heavy trades — buy doorsets well, mark them up 15–30%, and protect the labour rate against the temptation to absorb the evidence-gathering time. The accountability premium matters too: a fire door is a life-safety component, and a builder who installs and certifies correctly carries liability. Price that responsibility in rather than racing competitors to the bottom on a door that has to perform in a fire.

Red flags affecting price

• Mismatched components — a leaf from one system in a frame from another, or non-fire-rated ironmongery, can void the certification; budget to supply a complete compatible set.
• Out-of-square or damaged existing frames — a leaf swap becomes a full doorset replacement; survey before quoting a "swap" rate.
• Oversized or non-standard openings — bespoke certified doorsets cost more and have lead times.
• Existing intumescent gaps wrong — over-large perimeter gaps may mean the opening, not just the door, needs work.
• Glazing and vision panels — only certain doors are rated for glazing; cutting a panel into a solid fire door destroys the rating.
• Painted-over door tags — you cannot evidence the existing rating, so the door may need full replacement.
• Access and occupancy — occupied flats, schools in term time and care homes restrict working hours and slow the per-door rate.

What to quote (itemise)

Itemise so the responsible person can see a certified system: survey and measure; the certified FD30/FD60 doorset (state the rating); intumescent and cold-smoke seals; fire-rated hinges, closer, lock/latch with intumescent pads; any fire-rated glazing; removal and safe disposal of the old door; making-good and decoration; and — critically — the certification evidence pack (door tag photo, gap measurements, install photos) per door. For communal contracts, state the per-door rate, the inspection/evidence handling, and who holds the certification records. Spell out anything excluded (e.g. associated fire-stopping, frame builder-work) so it does not become a disputed variation.

Frequently Asked Questions

How much does it cost to fit a fire door?

A one-off domestic FD30 doorset supplied and fitted is typically £450–£900, and FD60 £650–£1,400. On volume communal work, FD30 doors run £350–£750 each installed and FD60 £750–£1,400. The certified doorset is the largest cost; labour is usually 30–45% of the total.

What is the labour/materials split on a fire door?

Labour is typically 30–45% of the installed cost and materials 55–70%, because the certified doorset and its fire-rated ironmongery dominate the bill. This is the opposite of labour-heavy trades — so accurate procurement and material markup matter more to your margin than the day rate alone.

Can I just swap the door leaf and keep the frame?

Only if you can evidence that the new leaf, the existing frame, the seals and the ironmongery together still form a certified system. Mixing components from different doorset systems can void the rating. If the frame is damaged, out of square, or its compatibility cannot be evidenced, price a full doorset replacement, not a leaf swap.

What net margin should I aim for?

Aim for 20–35% net on one-off domestic installs and 15–25% on competitive volume communal contracts. Protect the labour rate by pricing the certification evidence and making-good time explicitly, and buy doorsets well — material procurement drives margin more than the day rate on this work.
