Regulations and requirements for inspecting fire doors

Fire doors are an integral part of a building’s passive fire protection strategy, although their role in day-to-day fire safety often goes unnoticed. In the event of a fire, they are designed to resist the spread of smoke and flames for a defined period, protecting escape routes and enabling safe evacuation. Their performance also contributes to compartmentation, which can help limit the spread of fire within the building.

Understanding the regulations governing fire door inspections in the UK is essential for building owners, facilities managers, Responsible Persons and others with control over premises or fire safety measures. Compliance begins with correct specification and installation, but it also depends on ongoing inspection, maintenance and clear record keeping once the building is in use.
This article breaks down the legal framework for fire door inspections, clarifies common areas of uncertainty and provides a structured fire door inspection checklist to help organisations manage compliance with confidence.

Fire door inspections: key questions for compliance

Are fire door inspections a legal requirement?

In legal terms, the duty under the Regulatory Reform (Fire Safety) Order 2005 is to maintain fire safety measures, not to carry out inspection as a separate requirement in itself. The Responsible Person, broadly the employer or person in control of the premises, must ensure that fire doors are kept in efficient working order and good repair as part of a wider system of fire precautions within a building.

This can be achieved through regular inspections. Without checking the condition of a fire door, it is difficult to know whether it remains effective, if defects have developed, or whether maintenance is needed to keep it fit for purpose.

Specific inspection duties arise under the Fire Safety (England) Regulations 2022 for multi-occupied residential buildings in England over 11 metres in height. In those buildings, Responsible Persons must carry out quarterly checks of fire doors in common parts and use their best endeavours to check flat entrance doors at least every 12 months.

How often do fire doors need to be inspected?

Inspection intervals should be proportionate to risk, accounting for building type, occupancy levels and any relevant findings from prior inspections.

Guidance within BS 9999:2017 recommends regular inspection and maintenance of fire doors as part of a building’s wider fire safety management plan. Industry best practice generally aligns with:

• At least every six months in standard commercial environments
  
• More frequently in high-traffic or high-risk buildings, such as hospitals or schools
  
• Quarterly in common areas of residential buildings over 11 metres, as required by legislation

Inspection frequency should be proportionate to risk and guided by occupancy, legal duties and fire risk assessment findings. Factors such as high footfall, vulnerable occupants, frequent door use or previous defects may justify shorter inspection intervals.

Do you have to be certified to inspect fire doors?

While UK fire safety regulations do not specify a particular certification, it is stipulated that inspections must be undertaken by someone with appropriate competence.

The Fire Safety Order requires relevant measures to be maintained and obliges the Responsible Person to designate someone with the competence to assist in carrying out preventive and protective measures.

In legal and practical terms, competence is generally understood to mean having the necessary skills, knowledge, experience and behaviours (SKEB) to identify defects, interpret relevant standards and assess whether a fire door assembly remains fit for purpose. A competent inspector should be able to:

• Interpret fire test evidence, certification labels and manufacturer information
• Understand the relevant guidance, including standards such as BS 8214 and BS 9999
• Assess gaps, clearances and hardware against the tested specification or certified scope
• Identify modifications, replacement components or remedial works that fall outside the available evidence or guidance

Competence should be demonstrated through relevant fire door knowledge, training and experience that is supported by an understanding of the applicable standards, certification evidence and test data. The key point is that competence attaches to the individual carrying out the work.

Third-party certification or accreditation can still be useful, but it generally applies to the company rather than the individual inspector. For the Responsible Person, appointing a contractor from a recognised certification scheme may help show that reasonable steps were taken to select a provider with assessed systems and technical oversight. It does not, however, remove the need to establish that the individual inspecting the doors has the necessary skills, knowledge and experience.

What are the certification requirements for installing and inspecting fire doors?

Fire door certification applies at several levels: the door itself, its installation and the competence of those responsible for ongoing inspection and maintenance.

1. Product certification

Fire doors must be tested to recognised standards to demonstrate fire resistance performance. In the UK, this typically includes:

• BS 476-22 – Fire resistance of non-loadbearing elements
  
• BS EN 1634-1 – Fire resistance and smoke control tests for door assemblies

These standards set out controlled laboratory test methods that measure how long a complete door assembly can resist fire under test conditions, usually expressed as a time rating such as FD30 (30 minutes) or FD60 (60 minutes).

Importantly, fire test evidence applies only to the specific door assembly – including the door leaf, frame, glazing (if present), seals, hinges and other hardware. Changes to any of these components may affect whether the door continues to meet its stated fire resistance rating.

Many manufacturers also obtain third-party product certification through schemes such as Certifire. This does not replace fire testing; it simply confirms that ongoing production matches the tested specification through factory production control and independent oversight.

2. Installation certification

Fire performance depends not only on how a door is manufactured, but on how it is installed. A fire door is tested as a complete assembly, and its rating applies only when it is fitted in accordance with the tested specification. Incorrect gaps, incompatible hardware or unauthorised alterations can undermine the original fire test evidence and affect performance in a real fire.

Installation must therefore be carried out by someone with the appropriate competence and in accordance with the tested specification, relevant guidance such as BS 8214, and the fire safety requirements of relevant building regulations. In current building safety practice, competence is increasingly understood in terms of skills, knowledge, experience and behaviours for the individual carrying out the work, alongside organisational capability where a company is involved.

Third-party certification can support this by evidencing assessed company procedures and technical oversight, but it does not remove the need to ensure that the individual installer is competent for the work in question.

3. Inspection certification

For inspection, legislation focuses on competence rather than naming a mandatory qualification. As set out above, this depends on the individual having the appropriate skills, knowledge, experience and behaviours, supported by an understanding of relevant fire door evidence and guidance.

There is no universal statutory requirement for a specific inspection certificate. However, accredited training or third-party certification may help demonstrate competence, particularly in higher-risk premises or where more formal evidential records are required.

Why are these requirements linked?

Compliance depends on consistency between testing, manufacturing, installation and maintenance. A certified product can fail if installed incorrectly, and a correctly installed door can lose performance if it is not properly maintained. Each stage supports the integrity of the original fire test evidence and the building’s wider fire safety strategy.

Regulations and legal requirements for inspecting fire doors

1. Regulatory Reform (Fire Safety) Order 2005

This legislation applies to most non-domestic premises in England and Wales. It requires the Responsible Person to ensure that fire safety measures are maintained in efficient working order and good repair. Fire doors form part of those measures, so their condition must be monitored and maintained so that they remain effective.

2. Fire Safety (England) Regulations 2022

These regulations impose additional duties for residential buildings over 11 metres in height. They require quarterly checks of fire doors in common parts and use best endeavours to check flat entrance doors at least every 12 months. This establishes defined inspection intervals for higher-risk residential buildings.

3. Building Regulations – Approved Document B

Approved Document B outlines how buildings should meet fire safety requirements, including where fire-resisting doors are required and the performance they must deliver. Regular inspection helps ensure that those design intentions remain effective in practice.

4. BS 9999:2017

BS 9999:2017 sets out a comprehensive framework for fire safety in the design, management and occupation of buildings. Rather than prescribing fixed intervals, it supports a risk-based approach, linking inspection and maintenance activity to the nature of the building and its occupants. Although it does not carry statutory force, it is frequently referenced when establishing procedures for structured fire safety management.

5. BS 8214

BS 8214 focuses specifically on timber-based fire door assemblies and the practical realities associated with fitting and maintenance. It addresses issues such as installation tolerances, compatible components and ongoing upkeep, reinforcing the principle that performance depends on adherence to the tested specification. In practice, it serves as a technical benchmark for ensuring fire doors remain effective over time.

Taken together, these documents establish the regulatory and technical framework governing fire door inspection in the UK across commercial and residential premises.

Fire door inspection checklist

1. Certification and identification

• Check whether the door can be identified as a fire door through a certification label, plug, data plate or other available documentation.
  
• Confirm the stated fire resistance classification where this information is available (e.g. FD30, FD60, FD30S or FD60S).
  
• Check that the main components of the assembly, including the leaf, frame, glazing and hardware, appear consistent with the available product information.

If documentation is missing, the door may need a more detailed review against any available manufacturer information, certification evidence or relevant guidance.

2. Door Leaf Condition

• Inspect the door leaf for visible damage such as cracks, splits, holes, delamination or distortion.
  
• Check that any glazing is intact, securely fixed and appropriate to the assembly.
  
• Look for signs of wear or unauthorised alteration that could affect performance.

Damage to the leaf or glazing can affect the integrity of the assembly and should be assessed in the context of the original specification.

3. Gaps and Clearances

• Check perimeter and threshold gaps against the manufacturer’s data, certification evidence or other available supporting information.
  
• Where smoke control is required, pay particular attention to the threshold and perimeter clearances.
  
• Note any variation that appears inconsistent, excessive or likely to affect closing, latching or sealing.

Gaps should be judged against the tested or certified arrangement wherever that information is available, rather than against a single universal figure. Simple check guidance used in England also highlights the importance of excessive under-door gaps and damaged seals.

4. Intumescent and Smoke Seals

• Check that seals are present where required and appear continuous, secure and undamaged.
• Confirm that they are correctly fitted and not painted over, cut back or otherwise obstructed.
• Where smoke seals are part of the assembly, check that they remain intact and are serviceable.

Government fire door guidance notes that checks should help ensure doors remain in efficient working order and good repair, including seals and self-closing devices.

5. Hinges and Ironmongery

• Check that hinges, locks, latches, closers and other ironmongery appear suitable for the door and are securely fixed.
• Verify hinge type, size and quantity against the available specification where possible.
• Ensure screws are present, secure and appropriate to the hardware.

For timber fire doors, three hinges are commonly expected, but the controlling reference should still be the tested or certified specification for the particular assembly.

6. Self-Closing Devices

• Check that the door closes fully into the frame and latches from an open position.
• If relevant, test from more than one angle to confirm consistent closing action.
• Confirm that any electromagnetic hold-open device releases correctly on activation of the fire alarm system.
  

Government guidance for regulation 10 (under Article 24 of the Regulatory Reform (Fire Safety) Order 2005) specifically highlights checks to ensure self-closing devices are working and doors remain in efficient working order and good repair. Approved Document B also allows hold-open arrangements only in defined circumstances.

7. Door Frame and Surround

• Inspect the frame for damage, looseness or gaps at the junction with the surrounding wall.
  
• Check that any visible fire stopping around the frame appears intact and appropriate.
  
• Note signs of later works that may have disturbed the junction between frame and wall.
  

A fire door does not function in isolation; gaps or defects in the surrounding structure can undermine its ability to resist fire and smoke.

8. Signage and Labelling

• Check that any required fire door signage is present, legible and securely fixed.
  
• Ensure the wording is appropriate to the function of the door (for example, “Fire Door Keep Shut”) where relevant.
  
• Confirm that labels or plugs used for product identification have not been removed or obscured.

Signage helps support correct day-to-day use and reduces the risk of doors being misused or left in the wrong condition.

9. Modifications and Alterations

• Check for letterplates, grilles, replacement glazing, additional locks or other alterations.
• Confirm whether those changes are supported by the manufacturer, certification evidence or other relevant assessment.
• Record any alteration that cannot be matched to the available evidence.

Modifications outside the tested or assessed scope may affect the door’s fire resistance and should not be assumed to be acceptable without supporting evidence.

10. Record Keeping

• Record findings clearly, including location, condition, defects and any limits on the information available.
  
• Log recommended follow-up actions and timescales.
  
• Keep records in a form that can be reviewed alongside the building’s fire risk assessment and wider fire safety documentation.

The government’s fire door guidance makes clear that ongoing checks sit alongside, not instead of, the fire risk assessment, which considers the suitability of the doors in the first place.

Understanding compliance in context

Compliance is not achieved through a single inspection. Fire doors are subject to daily use, accidental damage, wear and refurbishment works, all of which can affect their condition over time. Even relatively minor changes to hardware, seals or clearances can compromise performance if not properly assessed.

This is where experienced specialists add value. Sharpfibre supports clients with structured inspection programmes, clear reporting aligned with relevant guidance, and practical recommendations for remedial action where defects are identified. That helps building owners and duty holders understand the condition of their fire doors, prioritise follow-up works and maintain a more robust approach to their ongoing compliance efforts.

Embedding inspection within a wider passive fire protection strategy helps ensure fire doors continue to perform as intended and remain aligned with the building’s broader fire safety arrangements.

Fire doors are engineered systems designed to perform under extreme conditions. Their effectiveness depends on correct installation, certified products, competent inspection and ongoing maintenance.

A thorough fire door inspection checklist, aligned with recognised standards and supported by competent professionals, forms the foundation of compliance.

For building owners and managers seeking clarity on fire door inspection requirements and wider UK legislation, working with experienced specialists can support a more informed and consistent approach to compliance. Any inspection findings and recommended works should be reviewed in the context of the building’s fire risk assessment and, where appropriate, detailed or approved by the fire risk assessor responsible for the premises.

Sharpfibre provides structured fire door inspections, detailed reporting and practical guidance tailored to the needs of commercial and residential premises. Their role is to help clients understand the condition of their fire doors and support the wider management of passive fire protection, with recommended actions considered alongside the fire risk assessor’s findings and the overall fire safety strategy for the building.
