A complete guide to fire door ratings, regulations, maintenance requirements and compliance obligations for UK businesses.
Fire doors play a vital role not only in a building's evacuation procedure but also in its passive fire protection. By stopping flames and smoke from spreading room-to-room, they give occupants the critical extra time needed to evacuate safely, and give emergency services the time needed to respond effectively.
Whether you manage a hospital, office, school, hotel or industrial facility, understanding your fire door obligations is essential. This guide covers everything you need to know: what fire doors are, how they are rated, where the law stands, and how to keep them compliant.
A fire door is a specially designed door assembly that helps prevent the spread of fire and smoke between different areas of a building for a specified period of time.
Unlike a standard door, a fire door is tested and certified as a complete assembly. This means the door leaf, frame, glazing (where fitted), intumescent and smoke seals, hinges, locks and self-closing device are all designed and tested to work together to provide the required level of fire resistance.
Fire doors serve a dual purpose. They act as a passive barrier, containing a fire within a compartment to limit structural damage, while simultaneously forming part of the escape route, allowing occupants to evacuate safely.
A fire door is not simply a fire-resistant door leaf. The entire assembly, including all hardware and seals, must meet the required standard to be effective.
Fire doors are classified according to how long they can resist the spread of fire under standard test conditions. The most common ratings in the UK are:
FD90 / FD120 - 90 to 120 minutes of fire resistance. Used in specific high-risk or critical infrastructure settings such as data centres, hospitals or multi-storey buildings with complex evacuation needs.
The "S" suffix (e.g. FD30S or FD60S) indicates that the door also provides smoke control, restricting the passage of cold smoke as well as fire. In most commercial buildings, doors with the "S" designation are required along escape routes.
The appropriate rating for your building depends on the outcomes of a fire risk assessment. Higher ratings are typically required in areas of greater risk, in taller buildings, or where evacuation may be slower due to the nature of the occupants.
Fire doors in the UK are governed by a clear regulatory framework. The main pieces of legislation and guidance include:
The FSO is the primary legislation covering fire safety in non-domestic premises in England and Wales. It requires the designated "responsible person", typically the employer, building owner or managing agent, to carry out a fire risk assessment and implement adequate fire safety measures. This includes ensuring that fire doors are correctly installed, regularly inspected and properly maintained.
These more recent pieces of legislation significantly tightened requirements for multi-occupied residential buildings, particularly following the Grenfell Tower fire in 2017. If you own or manage a high-rise residential building over 11 metres in height, you are subject to more stringent requirements, including quarterly checks of all fire doors in communal areas and annual checks of flat entrance doors.
Approved Document B outlines where fire doors must be installed, how they should perform and the standards they must meet in new and significantly altered buildings. It works alongside the FSO to provide a comprehensive framework for compliance.
British Standards provide guidance on fire resistance testing, performance and fire safety in buildings. BS EN 1634 covers fire resistance and smoke control testing for door and shutter assemblies. BS 9999 provides a risk-based framework for fire safety in the design, management and use of buildings.
Failure to comply with fire door regulations can result in significant penalties, enforcement notices from the Fire and Rescue Service, and, in the event of an incident, potential liability for injury or loss of life. Non-compliance may also invalidate your building's insurance.
Fire doors are typically installed in key locations throughout a building. Their placement is determined through a fire risk assessment and must take into account the building's layout, occupancy type and escape strategy. Common locations include:
The specific locations required in your building will be identified during a professional fire risk assessment. At Scutum, our experts carry out comprehensive assessments and advise on the correct fire door placement for your premises.
Having the right fire doors installed is only the first step. Regular inspections and fire door maintenance are a requirement of fire safety regulations, and neglecting this obligation is one of the most common compliance failures identified during Fire and Rescue Service inspections.
Fire doors are subject to daily wear and tear. Hinges loosen, seals degrade, self-closing mechanisms weaken and door frames can warp over time. A fire door that is not properly maintained may fail to perform when it matters most.
A professional fire door inspection and maintenance service checks all mechanical and passive components of the door assembly, including:
checked for correct installation, alignment and secure fixing
tested for correct operation and compliance
inspected for wear, damage or incorrect fitment
verified to ensure fire integrity is maintained at the letterbox aperture
assessed for ease of operation and compliance with escape requirements
inspected for excessive wear, damage or loss of integrity
tested to ensure the door closes fully and latches correctly from any open position
checked for warping, gaps or structural damage that could compromise fire resistance
inspected for cracks, missing beads or damaged intumescent seals
Both one-off inspections and regular maintenance programmes are available. For most commercial premises, an annual inspection is the minimum recommended. For higher-risk environments or buildings subject to the Fire Safety (England) Regulations 2022, more frequent checks are legally required.
Fire doors must be installed and maintained by a "competent" person, defined under the Fire Safety Order as someone who has the appropriate training, experience and knowledge to carry out the task correctly. This is not work that should be carried out by non-specialist building maintenance staff.
At Scutum, all our fire safety technicians are fully qualified to inspect and maintain fire doors, whether or not they were originally supplied and installed by us. We operate across a wide range of sectors and facilities, from offices and retail properties to schools, healthcare and industrial sites.
Under the Regulatory Reform (Fire Safety) Order 2005, responsibility for fire door compliance sits with the "responsible person". In most cases, this will be:
where the premises are a workplace
in the case of residential buildings
where they have control over the premises
The responsible person must ensure that fire doors are correctly installed, meet the required standards, are regularly inspected, and are properly maintained. They must also ensure that fire doors are not 'wedged' open or otherwise compromised; a common issue that can have serious consequences in the event of a fire.
Where buildings have multiple occupiers or landlords, responsibility can be shared. In these cases, it is important that all parties are clear on their respective obligations and that maintenance programmes are coordinated accordingly.
Fire and Rescue regularly identify the same recurring issues during inspections. Being aware helps avoid the most common pitfalls:
often due to worn or damaged closing mechanisms
which prevents the door from expanding to seal against fire and smoke
undermining their entire purpose as fire compartmentation
fire doors must be clearly labelled in accordance with regulations
a common issue when building maintenance teams replace ironmongery without checking compliance
Many of these issues are easily preventable with a regular maintenance programme. Identifying and rectifying them before an inspection, or before an incident occurs, is far less costly than the alternative.
Yes. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for any non-domestic premises must ensure that fire doors are regularly inspected and properly maintained. For high-rise residential buildings over 11 metres, the Fire Safety (England) Regulations 2022 impose additional requirements, including quarterly checks of communal fire doors.
For most commercial premises, a minimum of one professional inspection per year is recommended. In higher-risk environments, or where doors are subject to heavy use, more frequent checks may be appropriate. Current regulations stipulate communal fire doors in qualifying high-rise residential buildings must be checked at least every three months .
A full fire door inspection covers all mechanical and passive components: hinges, push bars, push pads, handles, letterboxes, self-closing devices, intumescent and smoke seals, door frames, and any glazing. The aim is to confirm that the door assembly will perform as intended in the event of a fire.
No. Fire door maintenance must be carried out by a competent person with the appropriate training and experience. Using unqualified staff to inspect or repair fire doors risks non-compliance and could result in doors that fail to perform in an emergency.
Non-compliance fire doors can result in enforcement action from the local Fire and Rescue Service, including improvement notices or prohibition orders. In serious cases, prosecution and fines may follow. Beyond regulatory consequences, non-compliant fire doors put lives at risk and may also invalidate your insurance in the event of a fire.
