Fire Door Services for Every Building Type

Fire doors are the most frequently used component in any building’s passive fire protection system. They are opened and closed dozens of times a day, propped open, damaged by everyday use, and often overlooked during building maintenance programmes. A fire door that does not close properly, has a damaged intumescent strip, or is missing a functioning closer is not a compliant fire door — it is a gap in the building’s fire compartmentation.

For Business Owners and Commercial Operators

Under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006, dutyholders in non-domestic premises must ensure appropriate fire safety measures are maintained in effective working order. Where a fire risk assessment identifies deficient fire doors, the dutyholder should take appropriate action through inspection, repair, upgrade, or replacement.

Bell carries out fire door inspections for commercial buildings, produces written reports identifying every deficiency on every door, and provides repair, upgrade, or replacement services to help bring deficient doors back into compliance. Every inspection is documented in the format required for a fire safety file.

For Facilities Managers

Managing fire doors across a multi-floor building or a property portfolio requires a systematic inspection programme, not an ad hoc response to visible damage. Scottish fire safety duties and the recommendations of BS 9999 and BS 8214 both support planned inspection schedules — typically six-monthly for high-traffic doors and annually for lower-frequency doors.

Bell’s planned fire door inspection contracts cover all fire doors in your buildings on a fixed schedule. We produce a deficiency report after every visit, prioritise remediation recommendations by risk level, and track outstanding items between visits. One contractor, full audit trail, complete documentation.

For Property Managers & Landlords

Fire door legislation for landlords has tightened significantly in recent years. In Scotland, landlord duties arise under Scottish housing legislation, fire safety legislation, HMO licensing requirements, and the specific fire safety obligations that apply to residential care and multi-occupied premises.

For landlords managing HMOs, apartment blocks, and residential care facilities, fire door compliance is increasingly subject to regulatory inspection. Bell provides inspection and maintenance services with documentation in the format required for compliance files, licensing applications, and regulatory returns.

What Is a Fire Door and How Does It Work?

A fire door is a door assembly — leaf, frame, hardware, and seals together — that has been tested and certified to resist the passage of fire and smoke for a defined period. It is not simply a thicker or heavier door. Every component of a fire door assembly must meet the required performance standard, and the assembly must be installed correctly for the certification to apply.

How a Fire Door Works

In the event of a fire, a fire door performs two functions: it prevents the spread of fire through a building by maintaining the integrity of fire compartment boundaries, and it protects escape routes by stopping smoke from filling corridors and stairwells. Both functions depend on the door being closed, undamaged, and correctly fitted with all required components in working order.

When the building temperature rises, the intumescent strips around the door leaf and frame expand, sealing the gap that would otherwise allow flames and hot gases to pass. Cold smoke seals prevent cold smoke from penetrating the gap even before temperatures rise high enough to activate the intumescent material.

1
Fire begins Temperature rises rapidly on one side of the door
2
Cold smoke seals activate Brush seals close the perimeter gap, blocking cold smoke immediately
3
Intumescent strips expand Heat causes strips to swell, sealing the frame gap against flames and gases
4
Compartmentation maintained Fire and smoke contained for the rated period — 30 or 60 minutes

Fire Door Components

Every component of a fire door assembly must be present, correct, and in working order. A single deficiency can compromise the entire assembly’s rated performance.

Door Leaf

The door panel itself, manufactured from fire-rated materials to the thickness required for the specified fire rating.

Common deficiency

Damage to the core, holes drilled without fire-rated plugs, or replacement with a non-certified leaf.

Door Frame

The frame into which the door is hung, certified as part of the door set. The leaf and frame must be from a certified assembly.

Common deficiency

Frame not part of the certified door set, or frame damaged or incorrectly modified.

Intumescent Strips

Strips fitted into grooves in the door leaf or frame that expand under heat to seal the gap and prevent fire passage.

Common deficiency

Missing, damaged, painted over, or the wrong specification for the door rating.

Cold Smoke Seals

Brush or fin seals that close the perimeter gap to prevent cold smoke penetration before heat activates the intumescent strip.

Common deficiency

Missing from doors that require them, or damaged so the seal no longer makes contact.

Door Closer

A mechanical device that ensures the door returns to the closed position after being opened. Required on all fire doors.

Common deficiency

Missing, adjusted to prevent full closure, or damaged so the door does not close fully.

Hinges

Three fire-rated hinges are required for most fire doors. The number and specification depend on the door weight and rating.

Common deficiency

Only two hinges fitted, non-fire-rated hinges, or hinges that allow the door to drop and fail to close fully.

Latch or Lock

A latch that holds the door closed in its frame. A door that bounces open is not providing fire compartmentation.

Common deficiency

Missing latch, broken latch mechanism, or incorrect strike plate alignment preventing engagement.

Glazing & Glazing Beads

Where glass is present, it must be fire-rated glazing with fire-rated beads. Standard glass is not acceptable.

Common deficiency

Standard float glass in place of fire-rated glazing, or glazing beads not certified for the door rating.

Certification Label

A plug or label in the door leaf confirming the door set's certification, manufacturer, and fire rating.

Common deficiency

Missing or obscured certification label, making it impossible to verify the door's rated performance.

Fire Door Ratings — FD30 vs FD60

Fire doors in the UK are rated by the number of minutes of fire resistance they provide when tested under standard conditions. The two most common ratings are FD30 and FD60.

Fire Door Ratings — FD30 vs FD60

Fire doors in the UK are rated by the number of minutes of fire resistance they provide when tested under standard conditions.

FD30
30 minutes resistance

Fire and smoke resistance for 30 minutes when fitted with appropriate smoke seals.

Typical locations

Domestic premises, offices, corridors in lower-risk buildings, flat entrance doors in residential blocks.

FD30S / FD60S
With smoke control

As above, with the 'S' suffix indicating the door has also been tested for smoke control at ambient temperature.

Typical locations

Any location where smoke spread is a specific concern — required in most commercial applications.

E / EI
European classification

E denotes integrity (fire containment). I denotes insulation (heat transfer). Equivalent to FD ratings for practical specification purposes.

Usage

Increasingly used in new build specifications alongside or replacing FD designations.

The correct rating for any given door position is determined by your fire risk assessment and the building's fire strategy. Where doubt exists, a higher-rated door is always preferable. Our engineers can advise on the correct specification during a site survey.

How Our Fire Door Installation Works

Fire door installation is not the same as fitting a standard internal door. Every component of the assembly must be compatible with the certification, the installation must follow the manufacturer’s installation instructions for the specific door set, and the completed installation must be documented. Here is how Bell manages the process.

1

Free Site Survey

A surveyor visits your building to assess the locations requiring fire doors, the door openings, the required fire ratings, the traffic volumes at each location, and any access or aesthetic requirements. For new build projects, we review the architectural drawings and fire strategy. No charge and no obligation.

2

Door Set Specification and Selection

We specify the correct certified door set for each opening — leaf and frame combination, fire rating, core type, and hardware package — in accordance with the fire strategy, the building's risk assessment, and BS 8214. Where specific aesthetic requirements apply (flush veneer, glazed panels, colour-matched frames), we source door sets that meet both the visual specification and the fire performance requirement.

3

Fixed-Price Quote

You receive a fixed-price quote covering the door sets, all hardware (closers, hinges, latches, intumescent strips, smoke seals), installation labour, and certification. For projects involving multiple doors, the quote includes a schedule of doors with the specification and location of each.

4

Professional Installation

Our certified engineers install the door sets in accordance with the manufacturer's installation instructions and BS 8214. The frame is fitted correctly, the leaf is hung on the correct number of fire-rated hinges, intumescent strips and smoke seals are fitted to the correct grooves, the closer is set to ensure full closure from any angle of opening, and the latch engagement is confirmed.

5

Commissioning, Documentation, and Handover

Each installed door is checked and documented — confirming the door set certification details, the hardware fitted, the installation date, and the competent person who carried out the work. An installation record is provided for every door. For new build projects, traceability documentation is provided in the format required for the building's golden thread information file.

Fire Door Features and Standards

A fire door installation is only as good as the components used and the care taken to install them correctly. Here is what defines a properly specified and installed fire door.

Certified Door Sets

Every fire door we install uses a leaf and frame that form a certified door set — tested together as an assembly to the relevant British or European standard. Substituting a non-certified frame, or fitting a certified leaf in a standard frame, voids the certification and means the door provides no guaranteed fire performance.

Correct Intumescent Strip Specification

Intumescent strips must match the specification of the certified door set — the correct width, depth, material, and expansion ratio. An incorrectly specified strip, even if physically fitted, may not seal the gap adequately under fire conditions. Bell uses only strips specified for the door set being installed.

Cold Smoke Seals

For any fire door where smoke control is required — which in practice means most commercial fire doors — brush or blade cold smoke seals are fitted around the perimeter of the door leaf. These close the gap between door and frame before heat activates the intumescent material, preventing cold smoke spread in the early stages of a fire.

Three Fire-Rated Hinges

Most fire doors require a minimum of three fire-rated hinges. The number and specification depend on the door weight, size, and rating. Bell specifies and fits the correct hinge count and specification for every installation. Using two hinges where three are required, or non-fire-rated hinges, is a certification failure and a commonly found deficiency at inspection.

Correctly Set Door Closers

Every fire door must have a functioning door closer that returns the door to the fully closed and latched position from any angle of opening. Bell sets closer tension during installation and confirms full closure before the installation is complete. A closer adjusted by building occupants after installation to reduce resistance — or removed entirely — is the most common reason a fire door fails its inspection.

Installation Documentation

Bell provides a written installation record for every door, including the door set manufacturer, the certification reference, the hardware fitted, the installation date, and the name of the competent person who installed it. This documentation forms the basis of the golden thread information for the building and is required for any subsequent inspection to be meaningful.

Why Choose Bell for Your Fire Door Installation?

Certified Competence

Fire door installation and inspection requires demonstrable competence — not just general joinery or building experience. Bell's fire door engineers hold recognised fire door competency qualifications and carry out installations and inspections in accordance with the guidance produced by the Guild of Architectural Ironmongers and the British Woodworking Federation's Fire Door Alliance.

The person installing or inspecting your fire doors can demonstrate their competence with documentation.

BS 8214 Compliant Throughout

BS 8214 is the British Standard covering fire door assemblies — timber-based fire doorsets. Every installation Bell carries out follows BS 8214's requirements for installation method, component specification, and documentation.

When a fire safety auditor, building control officer, or insurer asks for evidence that fire doors have been installed correctly, BS 8214 compliance is the benchmark they are working to.

Our fire door maintenance is independently certified under the BM TRADA Q-Mark Fire Door Maintenance scheme (STD058), giving you third-party assurance that our ongoing maintenance work meets this same standard.

Full Installation Documentation

Bell provides an installation record for every fire door we fit. This is not a generic completion certificate — it is a door-specific record identifying the door set, the hardware, the date, and the installer.

For higher-risk buildings where structured building safety records are required, this documentation supports the fire safety file and ongoing inspection history. For all other buildings, it is the evidence base that makes subsequent inspections meaningful.

Inspection Without Conflict of Interest

Bell carries out fire door inspections that identify deficiencies honestly — not with a commercial interest in recommending unnecessary replacement. Where a door can be brought back into compliance through hardware replacement, seal renewal, or closer adjustment, we say so and provide a cost for that work.

Where a door is beyond economic repair or where the door set is not certified for the required rating, we say that too. Building owners deserve an honest assessment, not a sales pitch.

Fire Door Inspection and Maintenance

A fire door that was correctly installed three years ago may not be a compliant fire door today. Hinges wear, closers are adjusted or removed, intumescent strips are painted over during redecoration, and doors are damaged by everyday use. Regular inspection is the only way to confirm that every fire door in a building is still performing its function.

How Often Should Fire Doors Be Inspected?

The frequency of fire door inspection depends on the building type and the level of use the doors receive. Guidance from the Fire Door Alliance and the recommendations of fire risk assessors generally point to:

Building / Door TypeRecommended Inspection Frequency
High-Traffic Commercial Doors Every six months minimum — including main corridors, stairwells, and busy floor areas.
Lower-Traffic Commercial Doors Annually — including plant rooms, store rooms, and less-used areas.
Flat Entrance Doors in Residential Blocks Inspection frequency should be determined by the fire risk assessment, building height, occupancy, and Scottish fire safety duties. Higher-risk or multi-occupied residential buildings may require more frequent checks.
Communal Fire Doors in Residential Blocks Typically every six months for higher-risk or heavily used communal areas, and annually for lower-risk blocks, subject to the fire risk assessment.
Care Homes, Hospitals, and Schools Every six months — high-traffic and high-consequence environments.

Remediation and Repair

Bell carries out remediation work as a follow-on from inspection: closer replacement or adjustment, intumescent strip replacement, hinge replacement, latch and strike plate adjustment, smoke seal replacement, and glazing bead replacement. Where a door leaf is beyond economic repair or where the door set is not appropriate for the required fire rating, we specify and install a replacement certified door set. Remediation is priced separately from the inspection visit and can be carried out on the same visit for minor items where the engineer carries the required parts.

What a Fire Door Inspection Covers

Bell's fire door inspection programme checks every door against a consistent checklist derived from BS 8214, PAS 24, and the guidance of the Fire Door Alliance. Each door is assessed on all of the following:

Inspection ItemPass Criteria
Certification Label Plug or label present and legible, confirming door set certification reference and fire rating.
Door Leaf Condition No damage to the door leaf surface or core, no holes, no cracks, and no modifications that could compromise the fire rating.
Frame Condition Frame undamaged, correctly fixed, and no gaps between frame and wall opening that would allow fire bypass.
Intumescent Strips Present on all four sides of the door leaf or frame as required, undamaged, not painted over, and correct specification visible or confirmed from installation record.
Cold Smoke Seals Present where required by the fire rating and specification, making full contact with the opposing surface on closure.
Hinges Correct number of fire-rated hinges, no loose fixings, door hanging squarely in frame, and no lateral movement.
Door Closer Fitted and functioning, door closes fully to the latched position from any position, and closing speed is appropriate — not so fast as to cause injury or so slow as to allow the door to stop before closure.
Latch Latch engages fully in strike plate on closure, no play in latch mechanism, and strike plate correctly positioned.
Gaps Around the Door Perimeter gap within the tolerances specified for the door set — typically 2–4mm at head and jambs, and 3–10mm at threshold.
Glazing Fire-rated glazing present where required, glazing beads fire-rated and correctly fitted, and no cracking or damage to glass.
Door Condition Overall Door closes fully to the latched position without manual assistance, with no warping or swelling affecting closure.

Deficiency Classification and Reporting

Bell's inspection reports classify every deficiency by risk level, allowing the dutyholder to prioritise remediation. A door that does not close is an immediate risk — it is providing no fire compartmentation at all. A door with a slightly degraded smoke seal is a lower but still real risk that should be addressed within a planned remediation programme.

Our reports are not generic pass/fail documents — they are actionable records that tell you what needs to be done, in what order, and why.

How Much Does Fire Door Installation and Inspection Cost?

Fire door costs depend on the door type, the fire rating required, the hardware specification, the number of doors, and whether this is a new installation into an existing opening or a replacement of an existing door. Inspection costs depend on the number of doors and the building layout. Here are the main factors.

Door Set Specification

A solid-core FD30 door set in a standard size with a basic hardware package costs less than a glazed FD60 door set with a rated vision panel, architectural ironmongery, and a concealed closer. The specification is driven by the fire strategy, the building's aesthetic requirements, and the location of the door.

Hardware

The hardware package for each door — closer, hinges, latch, intumescent strips, and smoke seals — must be compatible with the door set certification. Architectural-grade hardware specified by the building designer carries a premium over standard commercial hardware.

Number of Doors

Single door replacements carry a higher per-door cost than a programme of ten or twenty doors in the same building, where mobilisation, access, and waste disposal costs are spread across the job.

Access and Working Conditions

Doors in occupied buildings requiring out-of-hours working, temporary protection measures, or complex access arrangements add to the installation cost.

Inspection Programme

Inspection costs are driven by the number of doors and the building layout. Bell quotes inspection costs per visit based on the door count and building layout confirmed at a survey.

A fixed-price installation quote requires a survey to confirm the openings, the specification, and the access conditions. Inspection costs can be quoted from a confirmed door count and building description. Contact Bell to arrange a no-obligation survey.

Fire Door Legal Requirements in Scotland

The legal framework around fire doors is more complex than most building owners and facilities managers realise, and it has tightened considerably in recent years following the Grenfell Tower inquiry and subsequent legislation. Here is the current position.

Frequently Asked Questions About Fire Doors

A fire door is a door assembly — leaf, frame, hardware, and seals tested together — that has been certified to resist the passage of fire and smoke for a defined period. The most common ratings in the UK are FD30 (30 minutes) and FD60 (60 minutes). A fire door is not simply a thicker door — every component of the assembly must meet the required standard and the assembly must be installed correctly by a competent person for the certification to apply.

High-traffic commercial fire doors should be inspected every six months. Lower-traffic doors can typically be inspected annually. For multi-occupied residential buildings in Scotland, inspection frequency should be guided by the fire risk assessment, building type, occupancy, management arrangements, and relevant Scottish fire safety duties. Care homes, hospitals, and schools should inspect fire doors at least every six months given the high-traffic and high-consequence environment.

A certified fire door should have a plug or label in the door leaf — typically visible on the top edge or hinge edge — confirming the door set’s certification reference and fire rating. If the label is missing, it is not possible to verify the door’s rated performance without reference to original installation records. Bell’s inspection service includes checking and recording certification labels as a standard item.

No — not by propping, wedging, or any other means that bypasses the door closer. A fire door held open provides no fire compartmentation. The only compliant way to hold a fire door open is with a certified hold-open device linked to the building’s fire detection system, which releases the door to close automatically when a fire alarm is triggered. Bell installs fire alarm-linked hold-open devices for locations where staff legitimately need doors held open during occupation.

FD30 doors resist fire for 30 minutes under standard test conditions. FD60 doors resist fire for 60 minutes. Most internal fire doors in lower-risk commercial and residential buildings are FD30. FD60 is required for protected stairwells in taller buildings, for higher-risk areas such as plant rooms in certain buildings, and where the fire strategy requires a longer evacuation time or a longer window for fire service intervention. The fire strategy for the building determines which rating is required at each location.

ThIn Scotland, responsibility sits with the dutyholder — typically the building owner, employer, occupier, landlord, factor, or managing agent, depending on who has control of the premises. For residential blocks, this is usually the building owner, landlord, management company, factor, or managing agent. Responsibility cannot be passed entirely to a contractor — the dutyholder remains accountable for ensuring fire doors are inspected, maintained, repaired, and documented properly.

The deficiency is recorded in a written report with a risk classification. High-risk deficiencies — such as a door that does not close at all — should be addressed as a priority, which in practice means immediately or within days. Lower-risk deficiencies can be addressed within a planned remediation programme. Bell carries remediation parts on inspection visits and will carry out minor repairs on the same visit where the engineer has the required parts. A door that cannot be made compliant through remediation should be replaced.

Our operations are currently focused exclusively within Scotland. At this time, we do not provide services across the wider United Kingdom, though future expansion into additional regions may be considered as part of our ongoing growth strategy.
