Fire Door Cost

This guide breaks down the cost of fire doors in 2026, covering interior fire door cost, external fire door cost, installation and the factors that move prices up or down, so you can budget with confidence. The prices below cover the timber and steel doors most people are pricing up for a home or a straight replacement. Certified aluminium and glass doorsets are a different specification and are quoted per project rather than sold at a fixed unit price.

Fire door prices in 2026 typically range from £65 to £350+ for the door leaf alone, while a fully fitted fire door, including a compliant frame, intumescent seals, fire rated ironmongery and professional installation, generally costs between £450 and £1,200 per door. The final figure depends on the fire rating, the material, the size and configuration of the doorset and whether glazing is included. Specialist products such as aluminium and glass fire rated doorsets for commercial and residential developments are priced by quotation, as every doorset is manufactured to the requirements of the project.

How Much Does a Fire Door Cost in 2026?

There is no single answer to the cost of a fire door because the term covers everything from a basic timber door for a domestic hallway through to a double leaf glazed aluminium doorset for a commercial escape route. As a general picture of fire door prices across the UK market in 2026:

• Budget timber fire doors start from around £65 to £150 for the leaf only, often unfinished or primed ready for painting
• Mid range options such as oak veneer or panelled designs typically sit between £150 and £400
• Premium fire doors, including glazed designs, solid wood fire doors and custom made fire doors, can range from £400 to £800+
• Steel fire doors for commercial and industrial settings can cost £1,000 to £3,500 including the frame, with double fire doors at the upper end of that range

Aluminium fire rated doorsets sit in their own category. Because the leaf, frame, glass, seals and hardware are manufactured and certified together as a complete tested system, they are quoted per project rather than sold at a fixed unit price.

As a benchmark, a single leaf EI30 glazed aluminium doorset starts from around £3,000. Configuration has a big effect on the final price: toplights, sidescreens, wider spans and additional hardware can all push the cost well above that starting figure.

What Affects the Cost of Fire Doors?

Several factors determine fire rated doors price points, and understanding them helps explain why two doors that look similar can carry very different price tags.

Fire Rating

The level of fire resistance is the biggest single influence on price. Timber fire doors are commonly sold as half hour fire doors (FD30) or 1 hour fire doors (FD60), with FD90 and FD120 available for higher risk applications, and prices rise with each step up in rating. 

Aluminium glazed systems are classified under the European standard EN 13501-2 instead, with EI ratings that confirm both integrity and insulation. An EI 60 fire rating means the doorset holds back flames and smoke for 60 minutes while also limiting heat transfer to the protected side, which is a higher specification than an integrity only rating. 

Material

• Timber is usually the most affordable material, which is why wooden fire door price points start so low. 
• Steel sits at the top end for industrial use. 
• Aluminium offers a slim, modern alternative that supports large glazed areas, and its cost reflects the engineering involved in keeping a lightweight metal frame stable at extreme temperatures. Systems such as MB-78EI use specialist insulating inserts within the profile to achieve this.

Glazing

A fire door with glass costs more than a solid leaf because the glazing must be certified fire rated glass, not standard safety glass. A small fire door vision panel adds a modest premium, while fully glazed leaves and sidelights increase the fire rated glass door price considerably. The benefit is natural light and visibility, which is why glazed fire doors are so widely specified alongside fire rated glass partitions in offices, schools and healthcare buildings.

Size and Configuration

Standard single doors are the most economical. Double door fire door configurations, oversized leaves, overpanels and sidelights all add material and certification complexity, which increases the fire door and frame cost.

Frame and Hardware

A fire door only performs as tested when it is hung in a compatible fire rated frame with certified hardware. Fire door frames, intumescent strips, hinges, closers, locks and signage can add £100 to £300+ to the total and FD30 fire door frame kits are often sold separately from the leaf. Every component must carry test evidence for the complete assembly.

Certification and Compliance

Third party certified doorsets cost more than uncertified alternatives, but they are the only reliable way to evidence compliance. Fire door certification cost is built into the price of a certified product, whereas separate inspection and sign off for uncertified doors adds expense later. Fire door inspection cost typically runs from £10 to £25 per door for large portfolios, or more for one off surveys.

Timber or Aluminium Fire Doors?

Price is the obvious difference between the two, but it is rarely the deciding factor. On larger projects the door type has already been specified by an architect, so the question is not which material to buy, it is what the specification demands.

Where there is a real choice, the case for aluminium is about what the door does for the building. A fire rated aluminium door does not read as a fire door. There is a lasting assumption in the industry that fire doors have to be bulky and visually heavy, and many people are not aware a fire rated aluminium door exists at all. Slim profiles carry large areas of certified fire rated glass, so far more daylight reaches the space behind the door than a solid timber leaf allows, which is why these doors sit comfortably in high end projects.

One system also covers a range of fire ratings, with clear glass, obscure glass or solid panels depending on the room. The polyester powder coated finish can be specified in any colour, including dual-coloured profiles with one colour inside and another outside, which a standard timber fire door does not offer.

Interior Fire Door Cost

The internal fire door cost for a typical UK home or flat starts at around £65 to £150 for a basic FD30 leaf, rising to £150 to £400 for oak veneer and panelled styles and £400 to £800+ for glazed or bespoke designs. Interior fire doors are most commonly specified for flat entrance doors, doors onto escape stairways, kitchens and integral garages.

In commercial interiors, glazed aluminium fire doors are frequently chosen over solid timber because they preserve sightlines and daylight across a floor plate. These are supplied as complete certified doorsets, so the cost of internal fire doors in this category is always quoted against the specification of the project.

External Fire Door Cost

External fire doors must do two jobs at once: resist fire and stand up to the weather. That dual role makes the external fire door cost noticeably higher than internal equivalents, with prices for external quality fire doors commonly starting around £1,000 and rising with size, glazing and security requirements. A fire exit door price will also reflect hardware such as panic bars and access control.

Aluminium performs particularly well in external applications because it does not warp, swell or rot and a polyester powder coated finish protects the outside fire door from corrosion for decades. Our guide to external fire rated doors explains the performance criteria in more detail.

Fire Door Installation Cost

Fire door installation cost in the UK averages around £400 per door fitted, with labour alone typically £75 to £300 depending on region, complexity and whether the frame needs replacing. A full supply and fit, including frame, seals and ironmongery, generally lands between £450 and £1,200 per door, and most installations take two to three hours. The cost to replace fire door assemblies is usually higher than a straight swap because the existing frame often needs modification or renewal.

The fire door fitting cost matters because an incorrectly installed fire door cannot be relied upon to perform. Gaps, missing seals and non certified hardware are among the most common defects found during inspections. 

There is no legal requirement for the person fitting a fire door to hold a specific certification. What matters is competence: the installer must understand how fire doors work and fit the doorset exactly to the manufacturer’s instructions, as any deviation can invalidate the fire rating. Many duty holders choose third party certificated installers because it makes competence easier to evidence, but a knowledgeable joiner or contractor working to the installation guidance can fit a fire door correctly.

One point to be clear on: Aluminium Fire Systems is a manufacturer and supplier rather than an installer, so installation is not a service we offer. We can, however, recommend contractors, fabricators and installers so that you can get a cost for installation. 

Why Are Fire Doors More Expensive Than Standard Doors?

A fireproof door is an engineered system rather than a slab of material. The thickness of a fire door is typically 44mm or 54mm against 35mm for a standard internal door, and the core is built from fire resisting materials. Every doorset must pass furnace testing, and that test evidence must cover the exact configuration supplied, from the leaf and frame through to the hinges and seals.

The Fire Safety (England) Regulations 2022 introduced routine fire door checks in multi occupied residential buildings, and the Building Safety Act 2022 raised documentation standards across the industry. Certified products with full traceability cost more to produce, but they protect duty holders as well as occupants. Our article on the new law on fire doors in the UK covers what building owners now need to evidence.

Aluminium Fire Rated Door Costs

For commercial projects, glazed escape routes, high specification residential developments and external applications, fire rated aluminium doors offer slim sightlines, large glass areas and EI rated performance from EI30 up to EI90. Single leaf, double leaf and fire rated sliding door configurations are available, manufactured to the exact dimensions of the opening.
