Fire doors are one area of joinery where price should never be considered in isolation.
A fire door is not simply a heavier version of an internal door. It forms part of a fire-resisting assembly, and its performance depends on the door leaf, frame, hinges, seals, ironmongery, gaps and installation all working together correctly.
That means the cost of fire-door installation can vary considerably depending on what is already present and exactly what needs replacing.
As a broad guide, labour for fitting a fire door into a suitable existing frame might start from around £150–£250+ per door.
Where a complete fire doorset, frame alterations, specialist ironmongery or remedial work is required, the overall project cost can be considerably higher.
Here is what determines the price.
What Is Included in Fire Door Installation?
The scope of a fire-door installation can vary substantially.
At the simplest level, the work may involve replacing an existing door leaf where the existing frame has been assessed as suitable for the required installation.
More extensive work can involve:
- removing the existing door
- removing or modifying the existing frame
- installing a suitable new frame or lining
- fitting the fire-door leaf
- fitting suitable hinges
- installing intumescent seals
- installing smoke seals where specified
- fitting handles and latches
- fitting a suitable door closer where required
- installing other specified ironmongery
- checking and adjusting door gaps
- making good around the installation
This is why comparing fire-door prices without comparing the specification can be misleading.
Typical Fire Door Installation Costs in Leeds
There isn’t one universal rate, but the following provides a useful starting point.
Fire Door Leaf Into a Suitable Existing Frame
Where an existing frame is appropriate and only the door leaf and associated components require installation, labour might broadly start around:
£150–£250+ per door
The actual price depends on the door, frame condition, ironmongery and work required.
Fire Door and New Frame
Replacing both the door and frame is a more substantial job.
The existing frame needs removing, the opening prepared and the new assembly installed accurately.
Once materials, ironmongery and labour are included, a complete installation can cost several hundred pounds per opening, with specialist or higher-specification doorsets costing considerably more.
FD60 and Specialist Fire Doors
Higher-rated or specialist doors can be significantly more expensive.
An FD60 door, for example, may involve heavier construction and a different specification from a typical FD30 installation.
Bespoke dimensions, glazing, acoustic requirements, security hardware and specialist finishes can increase the cost further.
For these installations, the actual specification should be established before meaningful pricing is attempted.
Why Is a Fire Door More Expensive to Fit Than an Internal Door?
An ordinary internal door primarily needs to fit, operate correctly and look good.
A fire door has additional performance requirements.
The installer needs to consider things such as:
- door certification and specification
- permitted trimming
- frame compatibility
- hinge specification
- intumescent protection
- smoke control where required
- door gaps
- ironmongery
- closing action
Fire doors are also commonly heavier than standard internal doors.
Installation therefore requires more than simply trimming the door and hanging it on a pair of hinges.
The Door Leaf Is Only Part of the Cost
It is easy to compare the price of fire-door leaves online and assume that represents most of the project cost.
It doesn’t.
Depending on the installation, you may also need:
- a suitable frame or lining
- fire-rated hinges
- intumescent seals
- smoke seals
- door closer
- latch or lock
- handles
- signage
- glazing
- specialist hardware
- architraves and finishing materials
The labour involved in removing the existing installation and preparing the opening also needs to be considered.
Does the Existing Frame Need Replacing?
Not necessarily, but it needs to be suitable for the proposed installation.
The condition and construction of the existing frame matter.
An installer may need to consider:
- frame material
- dimensions
- condition
- rebates
- existing damage
- door stops
- fixing
- required seals
- compatibility with the proposed door
If the existing frame cannot form part of the required fire-resisting assembly, simply hanging a new fire-door leaf into it does not solve the problem.
Replacing the frame may therefore be necessary.
How Much Do Fire Door Materials Cost?
Material costs vary enormously.
A relatively straightforward FD30 timber door is very different from a bespoke FD60 glazed doorset with specialist hardware.
Factors affecting the door price include:
- fire-resistance rating
- size
- construction
- timber species
- veneer
- glazing
- acoustic performance
- security requirements
- finish
- certification
- bespoke manufacturing
For this reason, we prefer to price the actual specification rather than quote a generic material allowance.
FD30 vs FD60: What’s the Difference in Cost?
An FD30 door is designed to provide a minimum level of fire resistance of approximately 30 minutes under its applicable test conditions.
An FD60 door is intended to provide approximately 60 minutes.
The higher performance requirement can result in different door construction, frames, seals, glazing and ironmongery.
FD60 doors can therefore be more expensive to supply and install.
However, the required rating should come from the relevant specification or fire-safety requirements.
Choosing FD60 simply because it sounds better is not a substitute for establishing what the building actually requires.
Does a Fire Door Need Intumescent Seals?
Fire-door assemblies commonly incorporate intumescent protection.
Intumescent material expands when exposed to high temperatures, helping close the gap between the door and frame.
The required seal size, location and arrangement depend on the particular doorset or door assembly.
They should therefore be installed according to the relevant specification rather than selected arbitrarily.
What About Smoke Seals?
Where smoke control is required, smoke seals may also form part of the installation.
These are commonly combined with intumescent strips.
The purpose is different: intumescent material reacts to heat, while smoke seals are intended to restrict smoke passing through the gaps around the door.
The required configuration depends on the application.
Fire Door Hinges
Hinges are another component that should not be treated as an afterthought.
Fire doors are generally heavier than standard internal doors and the hinges form part of the overall installation.
The number, type, positioning and fire performance of the hinges should correspond with the applicable door or doorset specification.
Using unsuitable hinges to save a relatively small amount of money is poor economy on a fire-door installation.
Door Closers
Where a fire door is required to be self-closing, a suitable closer will also need to be installed and adjusted correctly.
The door needs to close reliably from different opening positions and engage properly with the frame.
A closer that is badly adjusted can result in a door that slams aggressively or, more importantly, fails to close completely.
The final setup matters just as much as fitting the hardware.
Why Fire Door Gaps Matter
One of the most important aspects of installation is achieving appropriate gaps around the door.
Too little clearance and the door may bind.
Too much clearance can compromise the intended performance of the assembly.
The correct tolerances depend on the particular door and installation specification.
This means an existing opening sometimes requires more work than expected before the door can be installed correctly.
Can a Standard Door Be Upgraded Into a Fire Door?
You should not assume that adding intumescent strips and fire-rated hinges turns an ordinary door into a fire door.
A fire door is manufactured and tested to achieve a specified level of performance as part of an appropriate assembly.
Where an existing door needs to provide fire resistance, its suitability needs to be properly established.
Replacing it with an appropriate fire-rated product is often the correct solution.
What Can Increase the Installation Cost?
Several common conditions can make a fire-door project more expensive.
Poor Existing Frames
Damaged, twisted or unsuitable frames may require replacement or remedial work.
Non-Standard Openings
Unusually large or small openings can require bespoke doors or additional alterations.
Glazed Fire Doors
Fire-resistant glazing requires an appropriate tested glazing system and can significantly increase material costs.
Specialist Ironmongery
Access control, security locks, panic hardware and other specialist components can increase both supply and installation costs.
Higher Fire Ratings
FD60 and other specialist assemblies can cost more than standard FD30 installations.
Decorative Finishes
Premium veneers, hardwood finishes and bespoke designs can substantially increase the cost of the door itself.
Making Good
Removing an existing frame can disturb plaster, decorations, skirting or surrounding finishes.
The quotation should make clear whether making good and decorating are included.
Fire Door Installation in HMOs
Fire doors are commonly encountered in houses in multiple occupation.
The required specification can depend on the property’s layout, licensing requirements and fire-risk assessment.
Rather than assuming every door requires the same product, landlords should establish the required fire strategy for the particular property.
This can prevent both under-specification and unnecessary expenditure.
Fire Doors for Flats and Communal Buildings
Flat entrance doors and doors protecting communal escape routes can have particularly important fire-safety functions.
Projects involving blocks of flats may also be subject to additional inspection, management and documentation requirements.
Where work forms part of a wider fire-safety programme, the installation should follow the specification provided by the responsible person, fire-risk assessor, building professional or other relevant competent party.
Fire Doors in Commercial Properties
Commercial fire-door requirements can be considerably more varied.
Doors may need to incorporate:
- panic hardware
- access control
- vision panels
- security systems
- automatic closers
- specialist signage
- acoustic performance
- higher fire-resistance ratings
The cost should therefore be based on the actual doorset schedule and specification rather than a residential per-door price.
Should You Replace One Fire Door or Several at Once?
Where several doors require replacement, completing them as one project can sometimes be more efficient.
Site setup, deliveries and labour can be organised across the complete package.
However, each opening still needs to be considered individually.
It is common for doors within the same property to have different sizes, existing frames or hardware requirements.
A bulk project should therefore not become an excuse for treating every opening as identical.
How Long Does Fire Door Installation Take?
A straightforward installation into a suitable existing opening may potentially be completed within part of a working day.
More involved installations can take considerably longer.
Replacing frames, modifying openings and installing complex ironmongery all increase the time required.
On larger projects, the most efficient approach is usually to survey all openings first and establish the specification before installation begins.
What Should a Fire Door Quote Include?
A good quotation should make it reasonably clear what is being supplied and installed.
Depending on the project, this may include:
- fire-door rating
- door leaf
- frame or lining
- hinges
- intumescent and smoke seals
- closer
- handles
- latch or lock
- glazing
- removal of existing doors
- disposal
- making good
- finishing
- labour
- VAT
This makes it much easier to compare quotations properly.
A cheap quote that excludes frames, hardware and finishing may ultimately cost more than a higher quotation that includes the complete scope.
Don’t Choose a Fire Door Installer on Price Alone
Competitive pricing matters, particularly when a landlord or commercial client is replacing numerous doors.
But fire doors are safety-critical components.
Installation quality should therefore carry considerably more weight than it might when comparing purely decorative joinery.
The person undertaking the work should understand that the manufacturer’s installation requirements and relevant fire-door specification take precedence over simply making the door fit the opening.
Getting an Accurate Fire Door Installation Quote
For an initial quotation, useful information includes:
- number of doors
- photographs of each opening
- approximate door sizes
- required fire rating
- whether frames are being retained
- glazing requirements
- required ironmongery
- property type
- location
- any fire-risk assessment or door schedule available
Where the specification is unclear, that should be resolved before final pricing and installation.
