Fire doors are a legal requirement in many UK buildings to protect escape routes and support compartmentation. If you are budgeting for compliance, refurbishment or replacement, one of the first questions is:
How much does a fire door cost in the UK?
The total cost depends on whether you are purchasing a single internal fire door, installing a complete fire-rated doorset, or upgrading multiple doors as part of a compliance programme.
In the UK, supply-only fire doors typically range from £115 to £650+ per door, depending on rating and finish. When professionally installed, most compliant internal FD30 fire door installations fall between £300 and £600 per door, while flat entrance or higher-specification doors frequently range from £600 to £1,200+ depending on hardware, certification and complexity.
This guide explains supply prices, installation costs, factors that affect pricing, and how to budget for compliant fire door upgrades.

Fire Door Supply Costs
Fire door prices vary based on rating, material, finish and whether the door is supplied as a leaf only or as a complete doorset.
Typical Supply-Only Price Ranges
| Fire Door Type | Typical UK Supply Cost |
|---|---|
| Basic internal FD30 door (unfinished) | £115 – £250 |
| Oak veneer or finished FD30 | £200 – £450 |
| FD60 fire door | £250 – £650+ |
| Glazed fire door | £300 – £700+ |
| Composite or flat entrance fire door | £900 – £1,500+ |
Prices vary depending on:
- Material (oak, laminate, MDF, composite)
- Fire rating (FD30, FD60)
- Whether smoke seals are integrated (FD30S)
- Glazing panels
- Acoustic or security performance
- Manufacturer certification
Doors supplied as complete fire-rated doorsets (leaf + frame + hardware package) generally cost more but simplify compliance.
Fire Door Installation Costs
Professional installation is essential. Incorrect installation can invalidate certification and reduce fire resistance performance.
Installation pricing normally excludes the cost of the door leaf itself unless clearly stated. When comparing quotations, confirm whether the price includes supply, installation, hardware, seals and certification documentation.
Typical Installation Cost Per Door
| Installation Type | Typical Cost |
|---|---|
| Straightforward internal replacement | £150 – £400 |
| Full doorset installation | £300 – £700 |
| Complex installations (frame alterations, structural works) | £500 – £900+ |
Costs increase where:
- Frames require replacement
- Walls require modification
- Intumescent strips and seals must be routed
- Hardware must be upgraded
- Certification evidence is required
- Multiple site visits are needed
Flat entrance doors in residential buildings often cost more due to security hardware, self-closing devices and compliance requirements.
Total Cost: Supply + Installation
In practice, the fully installed cost of a compliant fire door in the UK commonly falls within:
- £300 – £600 for basic internal FD30 installations
- £600 – £1,200+ for higher-specification or entrance doors
Large volume projects may reduce per-door cost through economies of scale.
What Affects Fire Door Installation Costs?
Front-page competitors consistently show these factors influence pricing:
1. Fire Rating
- FD30 (30-minute fire resistance)
- FD60 (60-minute fire resistance)
Higher ratings often require heavier cores and stronger hardware.
2. Smoke Control (FD30S / FD60S)
Smoke seals increase specification and installation complexity.
3. Door Hardware
Certified hinges, self-closers, glazing systems and ironmongery must be compatible with the door’s fire test evidence.
4. Building Type
Residential blocks, care homes, schools and healthcare buildings may require higher compliance standards and detailed documentation.
5. Certification Requirements
Fire doors must be installed in accordance with the manufacturer’s certification and recognised UK guidance to ensure they perform as tested.
Where third-party certification schemes apply (such as CERTIFIRE or Q-Mark), installation must follow the tested configuration precisely to maintain validity.
Relevant guidance and legislation include:
- Regulatory Reform (Fire Safety) Order 2005
- Approved Document B
- BS 8214 (Timber-based fire door assemblies)
New Build vs Replacement Fire Door Costs
Fire door costs can differ significantly between new construction and retrofit replacement projects.
In new builds, door openings are usually prepared to correct tolerances, reducing labour time and remedial works.
In refurbishment or compliance upgrade projects, additional costs may arise from:
- Removing and disposing of existing doors
- Altering frames or surrounding walls
- Upgrading hardware to current standards
- Making good decorative finishes
- Managing access in occupied buildings
Replacement projects in residential blocks often cost more than new build installations due to coordination and compliance documentation requirements.
Additional Costs to Consider
When budgeting for fire door upgrades, you should also account for:
- Removal and disposal of existing doors
- Frame repairs or replacement
- Making good plasterwork or finishes
- Upgraded ironmongery
- Resident access coordination (for flat entrance doors)
- Certification documentation
Ongoing inspection costs should also be factored into lifecycle budgeting.
In residential buildings subject to Regulation 10 (England), ongoing quarterly and annual fire door checks should also be included within long-term compliance budgeting.
See our guide on fire door inspection costs for typical compliance pricing.
Fire Door Installation and Legal Compliance
Fire doors form part of a building’s passive fire protection system and are referenced within Building Regulations guidance such as Approved Document B, as well as ongoing maintenance duties under the Fire Safety Order.
Improper installation can:
- Compromise compartmentation
- Invalidate fire door certification
- Lead to enforcement action
- Increase liability following a fire
Installation should therefore be carried out by competent persons using certified components and correct tolerances.
Fire door installation and specification must also align with wider UK fire door regulations, including Building Regulations guidance and ongoing maintenance duties. For a detailed overview of the legislation affecting fire doors in commercial and residential buildings, see our guide to fire door regulations.
Fire Door Replacement vs Repair
Not all defective fire doors require full replacement. Minor issues such as seals, closers or hardware may be repairable.
However, replacement is often required where:
- The core is damaged
- Certification labels are missing
- Excessive trimming has occurred
- Unauthorised modifications have been made
For guidance, see our article on whether fire doors can be repaired or must be replaced.
Budgeting for Multiple Fire Doors
For landlords, managing agents and facilities teams, compliance often involves dozens or hundreds of doors.
Budget planning should include:
- Initial compliance survey
- Phased replacement programme
- Annual inspection costs
- Ongoing maintenance
- Regulation 10 inspection duties (where applicable in England)
A structured compliance plan often reduces long-term costs compared to reactive replacement following enforcement.
Installation is only part of the compliance picture. Responsible Persons must also understand their ongoing fire door maintenance responsibilities, including inspection frequency, defect management and record-keeping duties under UK fire safety law.
Is a Cheaper Fire Door a False Economy?
Lower-cost fire doors may reduce upfront expenditure, but specification shortcuts can increase long-term risk.
Doors that are incorrectly installed, incompatible with their hardware, or supplied without traceable certification may:
- Fail inspection
- Require costly remedial works
- Lead to enforcement action
- Increase liability following a fire
In many cases, investing in compliant supply and competent installation reduces overall lifecycle cost by avoiding repeat visits and corrective works.
Conclusion
The cost of fire door supply and installation in the UK varies significantly depending on rating, specification and complexity.
As a broad guide:
- Installed internal fire doors commonly range from £300 – £600 per door.
- Higher-specification or flat entrance doors typically range from £600 – £1,200+.
- Full doorset installations with enhanced hardware and certification documentation may exceed this range depending on complexity.
Accurate budgeting requires understanding both supply and installation costs, alongside inspection and ongoing compliance duties.
