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

Quick Answer: A complete FD30 fire doorset (door, frame, intumescent seals, fire-rated ironmongery) supplied and fitted typically runs £450–£900 per opening in 2026, with FD60 sets at £650–£1,400. The headline going rate for replacing a fire door in a communal block is £400–£750 per leaf when working in volume. Labour is usually 30–45% of a fire-door install — the certified doorset is the big material cost, and the margin lives in getting the certification, gaps and seals right, not in cheap hardware.

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.
