Fire doors are one of the most critical life safety systems in any commercial or residential building. Yet they are also one of the most commonly neglected. A fire door that fails to close properly, or has damaged seals, can allow fire and smoke to spread far faster than occupants can evacuate, with potentially fatal consequences.

For facilities managers, keeping fire doors in working order is not simply good practice. It is a legal requirement under UK fire safety legislation. This guide sets out a practical fire door inspection checklist, explains how often checks should be carried out, and outlines what to look for during each inspection, whether you are managing a small office, a multi-tenanted building, or a large industrial site.

What Is a Fire Door and Why Does It Matter?

A fire door is a specially constructed fire-resisting door assembly, often referred to as a fire doorset when supplied as a complete tested system, that has been tested and certified to resist the spread of fire and smoke for a specified period, typically 30 minutes (FD30) or 60 minutes (FD60). Where smoke control performance has also been tested, the door will carry an S suffix, such as FD30S or FD60S.

The assembly consists of the door leaf, the frame, seals, ironmongery, and any glazing, all of which must work together as a tested and certified system. Replacing individual components with non-compatible products can invalidate the assembly's performance certification, even if the replacement appears physically similar.

Fire doors serve two key functions. First, they contain a fire within a compartment, slowing its spread and giving occupants more time to escape. Second, they keep escape routes free from smoke inhalation, which is a leading cause of death in fires.

Critically, a fire door is only effective when it is closed. A propped-open or damaged fire door offers no protection at all.

Legal Requirements for Fire Door Inspections in the UK

The legal framework for fire door maintenance in the UK is set out primarily in the Regulatory Reform (Fire Safety) Order 2005 (RRO), which applies to all non-domestic premises. Under the RRO, the Responsible Person, typically the employer, building owner, or occupier, is required to carry out and regularly review a fire risk assessment, and to implement any remedial measures identified.

The Fire Safety (England) Regulations 2022, which came into force on 23 January 2023, introduced additional requirements for residential buildings. Responsible persons for residential buildings whose top storey is over 11 metres above ground level must undertake quarterly checks of communal fire doors, and annual checks of flat entrance doors on a best endeavours basis.

Many organisations in higher-risk or taller buildings also adopt monthly visual checks as a matter of operational policy or because their fire risk assessment requires it, though these are not a separate statutory mandate under the 2022 Regulations.

The guidance document Fire Safety (England) Regulations 2022 published by the Home Office provides further detail on these obligations.

Failure to comply can result in enforcement action by the local fire and rescue authority, improvement notices, prohibition notices, and, in serious cases, prosecution.

How Often Should Fire Doors Be Inspected?

Inspection frequency will depend on the type of premises and the level of foot traffic the doors experience. The table below provides a general guide.

Frequency	What to Check
Monthly	Visual check by a competent person; check self-closer, gaps, seals visible condition, and that doors close and latch correctly
Every 6 months	Detailed inspection by a fire door inspector or suitably trained person; check all components, certification labels, ironmongery, and gap tolerances
Annually	Formal inspection and written record; consider third-party accredited inspector for high-risk or complex premises
After any incident	Inspect immediately after a fire, impact, flood, or significant building work affecting the door or its frame
After modifications	Re-inspect any fire door that has been altered, rehung, or had new ironmongery fitted before returning to service

Doors in high-traffic areas, such as stairwells, communal corridors, and main entrances, will typically need more frequent inspection than those in low-use parts of a building. Your fire risk assessment should inform the appropriate frequency for your specific premises.

Fire Door Inspection Checklist

The following checklist covers the key items that should be assessed during a formal fire door inspection. It can be used by a competent in-house inspector or adapted for use by a third-party fire door inspector.

Inspection Item	Pass	Fail	N/A	Notes / Action Required
Door leaf closes fully without manual assistance
Door leaf closes and latches securely from both sides
Self-closing device operates correctly on full release
Door does not drag on the floor or frame
Intumescent strips are present and fully intact
Cold smoke seals are present and undamaged
Glazing and glazing beads are secure and intact
Ironmongery (handles, locks, hinges) is complete and secure
All three hinges are present, undamaged, and correctly fixed
Door leaf shows no signs of warping, damage, or holes
Frame is secure, plumb, and free from damage or gaps
Certification label / plug is present and legible
Door signage (Keep Shut / Fire Door) is in place and legible
Gaps between door leaf and frame are within tolerances permitted by the doorset's certification (typically 2-4mm sides/top; threshold tolerance depends on seals and test evidence)
Any hold-open device is linked to the fire alarm system
Door is free from wedges, props, or unauthorised modifications

Step-by-Step: What to Check on a Fire Door Inspection

1. Door Leaf and Frame Condition

Begin by visually examining the door leaf and frame. Look for any holes, cracks, splits, or areas where the door has been damaged or modified. Even small holes compromise the fire resistance of the assembly. Check that the frame is securely fixed to the wall and that there are no gaps between the frame and the surrounding structure.

2. Gap Tolerances

Using a gap gauge or ruler, check the gap between the door leaf and the frame on all three sides (both vertical edges and the top). Unless the manufacturer's certification states otherwise, gaps at the sides and head are typically expected to be between 2mm and 4mm. At the threshold (bottom of the door), the gap should generally be no more than 8mm, though this depends on whether a drop seal or intumescent threshold strip is fitted, and on the specific test evidence for that doorset.

Gaps that fall outside the tolerances permitted by the doorset's certification indicate that the door may not seal correctly in the event of a fire.

3. Intumescent Strips and Cold Smoke Seals

Check that intumescent strips are present around the full perimeter of the door edge or frame, that they are continuous, and that there are no missing sections, cuts, or areas where the strip has lifted away. Damaged or missing intumescent strips must be replaced like for like, using a product of equivalent specification.

Cold smoke seals, usually a brush or rubber seal, should also be checked for damage or deterioration. Note that not all fire doors are required to have cold smoke seals, but where they are fitted, they must be maintained in good condition.

4. Self-Closing Device

Open the door fully and release it. The door should close completely and latch without any manual assistance. Check that the self-closer is correctly adjusted so that the door does not slam, but also does not slow to a stop before reaching the frame. A door that fails to close fully is non-compliant and unlikely to perform as intended in a fire, regardless of the condition of the rest of the assembly.

Where a hold-open device is fitted, check that it is linked to the fire alarm system and that the door releases and closes correctly when the alarm is activated.

5. Ironmongery

Check all hinges, handles, locks, letter plates (if present), and other ironmongery. All items should be present, secure, and undamaged. Most fire doors require a minimum of three fire-rated hinges in accordance with the door's certification and manufacturer instructions, though hinge requirements for steel doorsets or specialist assemblies may differ.

Any ironmongery that has been changed since the door was installed should be checked against the original certification to confirm it is compatible with the tested assembly.

6. Glazing

Where glazing is present, check that the glass is intact and that glazing beads are fully secured. Fire-rated glazing must not be replaced with standard glass. Check the edges of the glazing for any gaps or damage to fire-rated intumescent glazing seals.

7. Certification Label

A fire door should carry a certification label or plug, usually located on the top edge of the door leaf. This confirms the door has been manufactured and tested to a recognised standard. If no label or plug is visible, certification may still be verifiable through other sources, such as operation and maintenance manuals, installer records, or schedule documentation held by the building owner. If certification cannot be established through any of these means, a specialist assessment will be required to determine whether the door is suitable for continued use.

While third-party certification is strongly recommended and widely regarded as best practice, some older fire-resisting doors may rely on historical test evidence or documented assessment rather than a modern certification scheme. The key question is whether adequate evidence exists to demonstrate that the door assembly meets the required fire resistance standard.

8. Signage

Check that appropriate signage is in place. Self-closing fire doors in communal areas should carry a 'Fire Door Keep Shut' sign, while doors on escape routes that are normally held open should display 'Fire Door Keep Clear'.

9. Door Operation

Finally, check that the door operates smoothly. It should not drag on the floor or frame, should not stick, and should align correctly with the frame when closed. Any binding or misalignment may indicate that the door has dropped on its hinges, that the frame has moved, or that the building has settled, all of which require investigation.

Common Fire Door Defects and How to Address Them

The Fire Door Inspection Scheme (FDIS) and the BWF Fire Door Alliance regularly highlight the most common defects found during fire door inspections. Being aware of these can help you prioritise remedial work.

Damaged or missing intumescent strips: replace immediately using a like-for-like product

Incorrect gap tolerances: adjust hinges or have the door rehung by a competent installer

Defective self-closer: repair or replace the device; do not simply remove it

Propped-open doors: remove props and investigate the reason the door is being held open; consider whether a properly installed hold-open device is appropriate

Missing certification label: contact the original manufacturer or a specialist to assess the door

Damaged glazing seals: replace with fire-rated intumescent glazing tape or beads

Loose or incorrect ironmongery: replace with fire-rated equivalents compatible with the door's certification

Record Keeping and Documentation

Keeping accurate records of fire door inspections is essential for demonstrating compliance during a fire risk assessment review or an inspection by the fire authority. Records should include the date of each inspection, the name of the inspector, the condition of each door assessed, any defects found, and the remedial action taken and the date it was completed.

Where defects cannot be remedied immediately, a risk assessment should be carried out to determine whether the door can remain in use or should be taken out of service until it is repaired.

Maintenance management software can be particularly useful here. Systems such as Trefnus CMMS allow facilities teams to schedule recurring inspection activities, record findings against individual assets, attach photographs of defects, and track remedial work through to completion. This creates a clear audit trail that can be produced on demand.

Frequently Asked Questions

How often should fire doors be inspected in the UK?

There is no universal statutory minimum frequency for fire door inspections in non-residential premises. Inspection frequency should be determined by the fire risk assessment, taking into account the level of use and the risk associated with each door.

Many organisations adopt six-monthly formal inspections as good practice, and this frequency is commonly recommended by schemes such as the FDIS, but it is not a blanket legal requirement. Under the Fire Safety (England) Regulations 2022, responsible persons for residential buildings whose top storey exceeds 11 metres must carry out quarterly checks of communal fire doors and annual checks of flat entrance doors.

Who can carry out a fire door inspection?

A fire door inspection must be carried out by a competent person, meaning someone with the appropriate skills, knowledge, and experience to identify defects and understand their significance. This does not necessarily require a formal qualification, though for complex or high-risk premises it is advisable to engage a third-party inspector accredited through a recognised scheme such as the FDIS or the BWF Fire Door Alliance. Guidance on competence is set out in BS 8214, the British Standard covering fire door installation and maintenance.

What should I do if a fire door fails an inspection?

Any defect that prevents the door from performing its fire resistance function should be rectified as soon as possible. If the door poses an immediate risk, it should be taken out of service or secured in the closed position until repaired. All defects and remedial actions should be recorded in your maintenance log. Where the required repair is beyond your in-house capability, commission a competent fire door installer.

Can I repair a fire door myself?

Minor maintenance tasks, such as adjusting a self-closer or tightening loose ironmongery, can be carried out by a competent maintenance operative. However, any work that affects the structural integrity of the door, the frame, the seals, or the glazing should only be carried out by a specialist familiar with fire doorset requirements. Fire doors should be treated as tested systems; replacing components with non-compatible products, even apparently equivalent ones, can invalidate the assembly's fire resistance certification. BS 8214 provides guidance on installation and maintenance standards.

What is the difference between FD30 and FD60 fire doors?

FD30 fire doors are tested to resist the spread of fire for at least 30 minutes. FD60 doors provide at least 60 minutes of resistance. The appropriate rating for a given location is determined by your fire risk assessment, building design, and applicable building regulations. Higher-risk or taller buildings typically require FD60 doors in critical locations such as protected stairwells.

Do I need to keep records of fire door inspections?

Yes. Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person is required to record significant findings from the fire risk assessment and any measures taken. This includes fire door inspection records. Good record keeping also provides valuable evidence during enforcement visits and helps to demonstrate a proactive approach to fire safety management.

Conclusion

Fire doors save lives, but only when they are correctly maintained and regularly inspected. For facilities managers, a structured fire door inspection checklist is one of the most practical tools available for managing compliance and protecting building occupants.

By carrying out inspections at appropriate intervals, recording findings accurately, and acting promptly on any defects identified, you can demonstrate that your organisation is meeting its legal obligations under UK fire safety law and, more importantly, that you are providing a safe environment for everyone who uses your building.

If you manage a large portfolio of doors or multiple sites, consider implementing a maintenance management system to schedule, track, and document your inspection programme. Trefnus CMMS provides facilities teams with a straightforward way to build and maintain a compliant inspection record, without the need for complex software or cloud infrastructure.
