A fire door certificate is usually a document, report or record used to show that a fire door has been inspected, installed, manufactured or assessed against relevant fire safety requirements. For landlords, managing agents, freeholders and commercial property owners, it is often used as evidence that fire doors have been checked and that any visible defects, missing components or compliance concerns have been recorded.
In simple terms, a fire door certificate helps show whether a fire door is suitable, correctly fitted, properly closing and capable of supporting the building’s fire safety strategy.
However, there is one important point: the phrase “fire door certificate” can mean different things depending on the situation. It may refer to manufacturer certification, installation evidence, a fire door inspection report, or a compliance record following a competent inspection. It is not the same as a fire risk assessment, and it does not replace the legal duty to keep fire doors in good working order.
For London landlords, blocks of flats, HMOs, offices, shops and commercial premises, fire door certification is mainly about proving that the right checks have been carried out and that defects are being managed properly.

Fire Door Certification Explained
Fire door certification is the process of providing evidence that a fire door, doorset or fire door assembly has been tested, installed or inspected for fire safety performance.
A proper fire door is more than the door leaf itself. It normally includes the frame, hinges, intumescent strips, smoke seals, closer, latch, glazing, signage and any ironmongery fitted to the door. If one part is missing, damaged or incorrectly fitted, the whole door may fail to perform as expected during a fire.
A fire door certificate or report may confirm:
- the location of the fire door
- the type or rating of the fire door, where known
- the condition of the door leaf and frame
- whether the door closes fully into the frame
- whether smoke seals and intumescent strips are present and in suitable condition
- whether hinges, closers, latches and signage are suitable
- whether there are excessive gaps around the door
- whether glazing, letterboxes or vents are fire-rated
- whether repairs, upgrades or replacement are required
This gives the responsible person a clear record of what has been checked and what action is needed.
Is a Fire Door Certificate a Legal Requirement?
In many cases, the law does not use the exact phrase “fire door certificate” in the way landlords and property managers use it. The legal requirement is usually about having suitable fire precautions, carrying out a fire risk assessment, maintaining fire safety measures and keeping fire doors in effective working order.
For multi-occupied residential buildings, the responsible person must consider fire doors as part of the building’s fire safety arrangements. This is especially important for flat entrance doors opening onto common parts, communal corridor doors, stairwell doors and doors protecting escape routes.
For residential buildings over 11 metres in height, responsible persons must arrange quarterly checks of communal fire doors and annual checks of flat entrance doors. In all multi-occupied residential buildings, residents must also be given relevant fire safety instructions and information about the importance of fire doors.
So, while the exact document may be called a fire door certificate, fire door inspection report, fire door compliance report or fire door survey, the practical requirement is the same: you need evidence that fire doors have been checked, maintained and managed properly.
What Is the Difference Between a Fire Door Certificate and a Fire Door Inspection Report?
A fire door certificate and a fire door inspection report are often confused, but they are not always the same thing.
A fire door certificate may refer to evidence that the fire door or doorset was manufactured and tested to a recognised fire-resistance standard. This may include a label, plug, certificate number or manufacturer documentation.
A fire door inspection report is usually created after a competent person inspects the fire door on site. This report records the condition of the door, identifies defects and recommends remedial action.
A fire door installation certificate may be issued after a new fire door has been installed by a competent installer. This can help show that the installation was carried out according to the manufacturer’s instructions and relevant fire safety standards.
A fire door compliance report is often used by landlords, managing agents and property owners as a practical record following an inspection.
For most existing London properties, especially converted flats, HMOs and older blocks, a fire door inspection report is often more useful than asking only for a manufacturer certificate because the actual condition and installation of the door are what matter in day-to-day compliance.
Does Every Fire Door Need a Certificate?
Not every older fire door will have a visible certificate, plug, label or original manufacturer paperwork. That does not automatically mean the door is unsafe or must be replaced.
The important question is whether the fire door is suitable for its location, whether it matches the building’s fire safety strategy, and whether it is in good working condition.
A competent fire door inspection can help confirm whether the door appears suitable, whether any certification markings are visible, whether defects exist, and whether further evidence, repair or replacement is needed.
For new fire doors, certification and installation records are much easier to obtain and should be kept safely. For older properties, the inspection report becomes especially important because it gives the responsible person a documented record of the door’s current condition.
What Are Certificated Fire Doors?
Certificated fire doors are doors that have been tested and certified to show that they can resist fire for a specific period when installed correctly as a complete doorset or door assembly.
Common ratings include:
- FD30 – provides around 30 minutes of fire resistance
- FD60 – provides around 60 minutes of fire resistance
- FD90 – provides around 90 minutes of fire resistance
- FD120 – provides around 120 minutes of fire resistance
In many residential and commercial settings, FD30 and FD60 fire doors are common, but the required rating depends on the building type, layout, use, escape route and fire risk assessment.
A certificated fire door should not be judged by the door leaf alone. The frame, seals, hinges, closer, latch, glazing and any fitted components must also be compatible. A certified door leaf fitted badly or with the wrong components may not perform properly. For more basics of fire door identification, read our blog post How to Identify a Fire Door.
What Should a Fire Door Certificate or Report Include?
A useful fire door certificate or inspection report should be clear, specific and practical. It should not simply say “passed” or “failed” without explaining what was checked.
A strong report should include:
- property address
- inspection date
- inspector or company details
- list of inspected doors
- door reference numbers or locations
- visible fire rating or certification details, where available
- condition of the door leaf
- condition of the frame
- hinge condition and suitability
- closer operation
- latch operation
- smoke seal and intumescent strip condition
- gap measurements or comments on excessive gaps
- signage condition
- glazing, letterbox or air transfer grille checks
- defects found
- recommended remedial actions
- priority level for repairs
- photographs where needed
This gives landlords and managing agents a proper compliance trail. It also helps contractors understand exactly what needs repairing.
Why Fire Door Certification Matters for London Landlords and Managing Agents
Fire doors protect escape routes and help slow the spread of fire and smoke. In blocks of flats, they are especially important because residents may rely on common corridors, stairwells and protected routes to escape or remain safe during an incident.
For landlords and managing agents, fire door certification matters because it helps prove that the building is being actively managed. Without records, it becomes harder to show that checks were carried out, defects were identified and repairs were arranged.
Fire door documentation can be important for:
- landlords managing rental properties
- managing agents responsible for blocks of flats
- freeholders and resident management companies
- HMO landlords
- commercial property owners
- offices, shops, restaurants and warehouses
- schools, clinics and care-related premises
- property sale, lease or insurance enquiries
- post-fire risk assessment remedial works
A fire door report also helps prevent small defects from becoming serious compliance issues. Common problems such as missing closers, damaged seals, excessive gaps or doors being wedged open can reduce the effectiveness of the fire door.
Who Is Responsible for Fire Door Compliance?
The responsible person is normally the person or organisation with control over the premises. This may be the freeholder, landlord, employer, managing agent, building owner, facilities manager or another person responsible for fire safety management.
In blocks of flats, the responsible person must make sure fire safety arrangements are suitable for the common parts. This includes considering flat entrance doors where they open into common areas. To know more in details, visit Who is Responsible for Fire Doors in Flats?
In commercial premises, the employer, occupier or person in control of the building may have duties to manage fire risks and maintain fire safety measures.
The responsible person should make sure fire doors are:
- suitable for their location
- kept in good condition
- checked at appropriate intervals
- repaired when defects are found
- not wedged open
- not altered without proper consideration
- included in the fire risk assessment where relevant
- supported by clear inspection and maintenance records
What Is Checked During a Fire Door Inspection?
During a fire door inspection, the assessor checks whether the door can close correctly and whether the door assembly appears capable of performing its fire safety role.
Typical checks include:
Door leaf
The inspector checks for damage, warping, holes, cracks, unsuitable alterations or signs that the door may not be a proper fire-resisting door.
Door frame
The frame must be secure, suitable and in good condition. Damage, movement or poor fitting can reduce the effectiveness of the door.
Gaps around the door
Excessive gaps around the top, sides or bottom of the door can allow smoke and fire to pass through. Gap issues are one of the most common fire door defects.
Hinges
Fire doors normally require suitable fire-rated hinges. Missing screws, damaged hinges or incorrect hinge types may be flagged.
Door closer
The door should close fully into the frame without sticking, slamming incorrectly or stopping short. A fire door that does not close properly cannot do its job.
Smoke seals and intumescent strips
The inspector checks whether seals are present, damaged, painted over, missing or loose. These components help restrict smoke and fire spread.
Latches and locks
The latch should engage properly. Incorrect locks or damaged hardware may affect the door’s performance.
Glazing and vision panels
Any glass in a fire door should be suitable fire-rated glazing and properly installed.
Letterboxes and vents
Flat entrance doors often have letterboxes. These should be suitable for use in a fire door. Unprotected openings can weaken the door.
Signage
Fire door signage may be required depending on the location and use of the door. Missing or incorrect signage may be listed as a defect.
How Often Should Fire Doors Be Checked?
The inspection frequency depends on the building type, risk level, use and legal duties.
For multi-occupied residential buildings over 11 metres, communal fire doors must be checked quarterly and flat entrance doors annually. For other buildings, the fire risk assessment should help determine a suitable inspection and maintenance routine.
High-use buildings may need more frequent checks because doors are more likely to become damaged. This includes hotels, schools, care settings, offices, commercial buildings and busy blocks of flats.
A practical approach is:
- regular visual checks by the building manager or responsible person
- formal fire door inspections at suitable intervals
- immediate checks after damage, works or tenant alterations
- follow-up inspections after repairs or replacements
The key point is that fire doors should not be ignored until the next fire risk assessment. They need ongoing management. For more details visit our blog post How Often Do Fire Doors Need to Be Inspected?
Common Fire Door Defects Found in London Properties
Many London properties have older doors, converted layouts, shared hallways and high-traffic communal areas. This makes fire door defects common.
Typical issues include:
- door not closing fully
- door closer missing, disconnected or weak
- excessive gaps around the door
- damaged or missing smoke seals
- damaged intumescent strips
- unsuitable hinges
- missing screws
- damaged frames
- non-fire-rated glazing
- unsuitable letterboxes
- doors wedged open
- missing fire door signage
- holes drilled through the door
- tenant-installed locks affecting performance
- doors cut down too much after flooring changes
- poor previous installation work
These problems should be recorded and repaired by competent professionals. Fire doors should not be adjusted casually because small changes can affect their fire performance. Read the blog post How to Adjust a Fire Door Closer Safely in the UK?
Can a Fire Door Be Repaired, or Does It Need Replacing?
Some fire door defects can be repaired. Others may require replacement.
Minor issues such as damaged seals, missing signage, loose screws or closer adjustment may be repairable if the door assembly remains suitable. More serious issues such as major damage, excessive gaps, unsuitable door leaves, badly altered doors or unknown performance may require replacement.
The decision should be based on the inspection findings, the door location, the risk level and whether the door can be restored to a suitable condition.
A fire door inspection report should clearly explain whether repair, further investigation or replacement is recommended.
Is a Fire Door Certificate the Same as a Fire Risk Assessment?
No. A fire door certificate or inspection report is not the same as a fire risk assessment.
A fire risk assessment looks at the wider fire safety arrangements of the building. It considers escape routes, fire hazards, alarms, emergency lighting, fire doors, management procedures and people at risk.
A fire door inspection focuses specifically on the condition and performance of fire doors.
In many properties, both may be needed. A fire risk assessment may identify that fire doors need further inspection, repair or replacement. A fire door inspection report then provides more detailed findings for each door.
When Should You Book a Fire Door Certificate or Inspection?
You should consider booking a fire door inspection if:
- you manage a block of flats
- your fire risk assessment recommended fire door checks
- you are a landlord with an HMO
- you own or manage a commercial property
- doors are damaged or not closing properly
- tenants have changed locks or altered doors
- you do not have records for existing fire doors
- you need evidence for managing agents, insurers or compliance files
- you are completing fire safety remedial works
- your building is over 11 metres and requires routine fire door checks
Early inspection is usually cheaper than leaving defects until they become urgent.
Frequently Asked Questions
What is a fire door certificate?
A fire door certificate is a document, report or record that provides evidence relating to a fire door’s certification, installation, inspection or compliance condition. In practice, landlords and managing agents often use the term to mean a fire door inspection report showing whether the door has defects and what remedial work is needed.
Is fire door certification required by law?
The law usually focuses on maintaining suitable fire precautions and keeping fire doors in good working order rather than using the exact phrase “fire door certificate”. However, responsible persons should keep evidence of checks, inspections, maintenance and remedial action.
What is the difference between a certified fire door and a fire door inspection report?
A certified fire door usually has evidence that the door or doorset was tested to a fire-resistance standard. A fire door inspection report records the current condition of an installed fire door and identifies defects, missing parts or repair needs.
Do flat entrance doors need to be checked?
Yes, flat entrance doors opening into common parts are important in multi-occupied residential buildings. In buildings over 11 metres, responsible persons must arrange annual checks of flat entrance doors and quarterly checks of communal fire doors.
Can a normal door be upgraded into a fire door?
A normal internal door should not be assumed to be a fire door. Some doors may be upgraded in limited circumstances, but this depends on the door, frame, components and required fire performance. A competent inspection is needed before relying on any upgrade.
How long does a fire door inspection take?
The time depends on the number of doors, property layout and condition of the doors. A small property with a few doors may be completed quickly, while a block of flats or commercial building with many doors will take longer.
Who can issue a fire door certificate?
A competent fire door inspector, fire safety professional or qualified contractor may issue a fire door inspection report or certificate depending on the type of service provided. The person should understand fire door assemblies, inspection requirements and relevant fire safety standards.
What happens if a fire door fails inspection?
The report should list the defects and recommended remedial actions. Some issues may be simple repairs, while others may require replacement. The responsible person should arrange suitable remedial work and keep records.
Is a fire door certificate the same as a fire safety certificate?
No. A fire door certificate or report focuses on fire doors. A fire safety certificate is a broader term and may relate to wider fire safety checks, fire risk assessment or fire safety compliance evidence.
How often should fire doors be inspected?
Inspection frequency depends on the property type, use and risk level. In residential buildings over 11 metres, communal fire doors need quarterly checks and flat entrance doors need annual checks. Other buildings should follow a risk-based inspection routine.
