Fire Door Installation Cost – UK Prices, Fitting and Replacement Guide 2026

The cost of fire door installation in the UK depends on the fire rating, door construction, frame condition, ironmongery and whether the job involves a straightforward replacement or a complete certified doorset. A fire door is a life-safety component, so correct specification and installation are more important than simply choosing the cheapest door.

Through FraserBond.com, homeowners, landlords, freeholders, managing agents and commercial property owners can explore fire-door installation, replacement and wider property-maintenance services across London and the UK.

How Much Does Fire Door Installation Cost?

For budgeting, a straightforward internal FD30 fire-door replacement can commonly run from several hundred pounds per opening, while complete installations involving a new frame, certified ironmongery, closer, seals and making good can cost considerably more.

The final quotation depends on exactly what is being replaced. A price advertised for a fire-door leaf alone should not be compared directly with a quotation for an entire compliant doorset.

Typical Fire Door Cost Breakdown

A quotation may need to cover:

Ask for an itemised quotation so it is clear whether the price is for the door alone or the complete installation.

FD30 Fire Door Installation Cost

FD30 generally refers to a fire door designed and tested to provide at least 30 minutes of fire resistance when installed as part of the appropriate assembly.

FD30 doors are widely encountered in residential buildings, including certain flats, houses in multiple occupation and other locations where the building's fire strategy requires them.

The cost increases where the existing opening requires:

• New frame
• Adjustment to structural opening
• Intumescent strips
• Smoke seals
• New closer
• Fire-rated hinges
• New lock or latch
• Fire-resistant glazing
• Decoration

The correct specification should be determined from the requirements applying to the building rather than simply replacing an existing door with something that looks similar.

FD60 Fire Door Installation Cost

An FD60 fire door is designed for a higher period of fire resistance than an FD30 assembly and can therefore be more expensive.

FD60 doors may require heavier or different:

• Door leaves
• Frames
• Hinges
• Seals
• Closers
• Glazing systems
• Ironmongery

They are commonly associated with situations where the building's fire strategy requires a higher level of compartmentation.

Never downgrade an existing fire-door specification without appropriate professional justification.

Fire Door Replacement Cost

Replacing only the door leaf may initially appear cheaper.

However, the existing frame must be suitable for the replacement door and required fire performance. Problems can arise where an old frame is:

• Damaged
• Warped
• Incorrectly sized
• Poorly fixed
• Incompatible with the new doorset
• Unable to accommodate the required seals

In these situations, replacing the complete door and frame may provide a more appropriate solution.

Fire Door and Frame Installation

A complete fire-door installation can involve:

Survey → Door/Frame Specification → Removal → Opening Preparation → Frame Installation → Door Hanging → Seals → Ironmongery → Closer → Adjustment → Inspection → Making Good

This is more involved than hanging an ordinary internal door.

The effectiveness of the finished installation depends on the complete assembly, including the door, frame, seals, ironmongery and surrounding construction.

Flat Entrance Fire Door Cost

Flat entrance doors require particular attention because they may form an important part of the building's compartmentation and escape strategy.

A replacement can involve:

• Fire-rated doorset
• Smoke-control requirements
• Self-closing device
• Fire-rated hinges
• Locks
• Letter plate
• Door viewer
• Threshold details
• Intumescent and smoke seals

In blocks of flats, do not replace an entrance fire door solely on the basis of appearance or price. Freeholder or managing-agent requirements and the building's fire-safety arrangements may need to be considered.

Fire Doors in Blocks of Flats

Fire doors in multi-occupied residential buildings are subject to important safety requirements.

Under the Fire Safety (England) Regulations 2022, responsible persons for residential buildings over 11 metres must undertake checks of communal fire doors at least every three months and use best endeavours to check flat entrance fire doors at least every 12 months.

The government guidance emphasises checking that self-closing devices operate effectively and that doors, frames and glazing are not damaged or defective.

Fire Door Installation for Landlords

Landlords should not treat a fire door as an ordinary replacement joinery item.

Depending on the property, fire doors can be relevant to:

• Flat entrance doors
• HMOs
• Protected escape routes
• Doors between certain risk areas
• Converted buildings
• Purpose-built blocks

The required arrangement depends on the property, its use, layout and applicable fire-safety requirements.

For HMOs in particular, the appropriate fire strategy should determine where fire doors are required and their specification.

Fire Door Installation in HMOs

Fire doors are frequently an important component of HMO fire precautions.

Depending on the building and fire-risk assessment, requirements can include:

• Fire-resistant doors
• Self-closing devices
• Smoke seals
• Intumescent seals
• Appropriate hinges
• Suitable locks and latches
• Protected escape routes

Local authority requirements and the specific property configuration should be checked rather than relying on a generic specification.

Fire Door Installation in Commercial Buildings

Commercial premises can require fire doors between:

• Corridors
• Staircases
• Plant rooms
• Offices
• Storage areas
• Kitchens
• Protected escape routes
• Different fire compartments

The correct fire resistance and door configuration should come from the building's fire strategy, risk assessment and applicable regulatory requirements.

Fire Door Installation in London

Fire door installation costs in London can be higher because of labour rates, parking, access, building-management requirements and the complexity of working in occupied apartment buildings.

Costs can also increase for:

• Bespoke door sizes
• Period properties
• High-end finishes
• Apartment entrance doors
• Multiple locks
• Access-control equipment
• Fire-rated glazing
• Restricted working hours

For several doors, request a schedule showing the specification and price for each opening.

What Makes Fire Door Installation Expensive?

Fire Rating

Higher-performance doorsets can cost more.

Door Size

Non-standard openings may require bespoke products.

Frame Condition

A damaged or incompatible frame can turn a door-leaf replacement into a complete doorset installation.

Glazing

Fire-resistant glazed panels require appropriately tested systems.

Ironmongery

Hinges, locks, latches and closers must be appropriate for the required installation.

Decoration

Some quotations include finishing while others leave the door ready for de
