Fire Door Costs: Supply and Fit Prices for FD30 and FD60
By the DC Fire & Security engineering team — installing and maintaining fire and security systems since 2010. Updated June 2026.
Quick answer
Supply and fit in 2026: an internal FD30 door costs £600–£1,200 installed, a flat entrance FD30S doorset £850–£1,600, and FD60 adds 30–60%. A glazed aperture adds £150–£400. On volume programmes — blocks, schools — per-door rates come down 15–30%. What actually separates a fire door from an expensive door is the certification chain: either a certified doorset or a certificated installer.
The price menu, decomposed
| Item | Range installed | Notes |
|---|---|---|
| Internal FD30 (corridor/office) | £600–£1,200 | Leaf, frame works, seals, furniture, certification |
| Flat entrance FD30S doorset | £850–£1,600 | Complete certified doorset + closer + letterplate/viewer rated |
| FD60 doors | +30–60% on FD30 | Heavier cores, spec hardware |
| Glazed vision panels | +£150–£400 | Fire glass + certified glazing system |
| Riser/cupboard doorsets | £500–£900 | Smaller leaves, keep-locked logic |
| Volume programmes (10+ doors) | −15–30% per door | Mobilisation amortised; blocks and schools |
| Frame replacement where needed | +£150–£400 | Fire doors are assemblies — rotten frames void leaves |
Doorsets vs door blanks: the certification fork
Two compliant routes exist: certified doorsets (leaf + frame + seals + hardware tested and supplied as one unit — fitted per manufacturer instructions, certification travels with the product; the post-Grenfell direction of travel, mandatory thinking for flat entrances) versus leaf-and-frame assembly by certificated installers (FIRAS/BM TRADA installer schemes evidencing the workmanship that makes components perform as tested). Doorsets cost 10–25% more in product, less in labour risk; site-assembled doors lean entirely on installer competence and documentation. What fails inspections later is the third route — a fire-rated leaf hung by a general chippy into an existing frame with whatever hinges were van-stock: each component arguably fine, the assembly unevidenceable (the identification guide's 'cannot prove' bucket, freshly manufactured).
Getting quotes that mean something
Fire door quotes compare only when they state: certification route (doorset product certification or installer scheme — named), full assembly scope (frame condition addressed, seals, closers per the closers guide, rated furniture and any letterplates/viewers per the modification rules), gap-setting to tolerance (the 3mm discipline — installation is where gaps are born), documentation deliverables (installation certificates, doorset data, photographic records — the golden-thread expectation in blocks), and making-good/decoration boundaries. Volume buyers (agents running flat-entrance programmes per the flats regulations guide, schools phasing per budget years) should demand per-door schedules with condition-dependent pricing bands — survey-light volume quotes hide condition risk in either their price or your variation orders. Our installation page details the certificated process; the survey produces door-by-door honesty before any number is promised.
