Internal fire door regulations are a cornerstone of fire safety in the UK yet they are often misunderstood or applied inconsistently across different building types. Whether you manage a block of flats, oversee a commercial building or operate a public space, knowing exactly which rules apply to your premises is essential. Compliance is a legal requirement and a critical component in protecting occupants, controlling the spread of fire and safeguarding property.
The legal framework
Internal fire door regulations in the UK are governed by three main frameworks, each with its own scope and obligations. Understanding which applies to your building is the first step in ensuring compliance.
- Regulatory Reform (Fire Safety) Order 2005 (RRFSO)
This legislation is the primary reference for non-domestic buildings, including offices, commercial premises, public buildings and the common areas of blocks of flats. Under Article 17, the designated responsible person—often the building owner or manager—must ensure that fire doors are “subject to a suitable system of maintenance and are maintained in an efficient state, in efficient working order and in good repair.” Neglecting these duties is not a technical breach; it is a criminal offence. - Fire Safety (England) Regulations 2022
Introduced following recommendations from the Grenfell Tower Inquiry, these regulations focus specifically on multi-occupied residential buildings containing communal areas. They place particular emphasis on flat entrance doors, requiring quarterly checks in communal parts and annual inspections of individual flats on a best endeavours basis. Residents must also be informed about the role of fire doors and how they contribute to overall fire protection measures. - Approved Document B (Building Regulations)
For new builds, extensions and significant refurbishments, Approved Document B sets technical standards for internal fire doors, including placement, fire rating, construction and materials. Volume 1 applies to dwellings and Volume 2 to all other buildings, ensuring that new installations meet the required minutes of protection against fire.
What internal fire door regulations cover
A compliant internal fire door is more than just a labelled leaf. It encompasses the entire doorset or assembly: the door leaf, door frame, hinges, intumescent strips, smoke seals, glazing panels and self-closing device. Each component must meet the required fire resistance rating. Installing a door with incompatible hardware invalidates the rating and breaches fire door regulations.
The primary function of fire doors is to slow the spread of fire and smoke, protecting escape routes and giving occupants valuable time to evacuate. The FD rating specifies the duration of this protection under test conditions. For example, FD30 doors should provide a minimum of 30 minutes while FD60 should provide a minimum of 60 minutes. The correctly required rating for each door is determined by the fire risk assessment, not by cost or convenience.
Responsibilities of building owners and managers
The “Responsible Person” which can include Property owners and facilities managers carry legal accountability for fire door safety. This includes:
- Ensuring all internal doors intended as fire doors are in good working order
- Carrying out regular inspections including checks on self-closing devices, door frames, intumescent and smoke seals
- Maintaining records of inspections and remedial work
- Including fire doors in the building’s fire safety strategy and risk assessments
For blocks of flats, this covers both the front doors of individual flats and doors in common parts. In commercial buildings, fire doors protect habitable rooms and means of escape, which makes regular checks equally vital.
Inspection and maintenance
Quarterly checks of communal fire doors and annual inspections of flat entrance doors are considered best practice under current regulations. Competent professionals should carry out inspections to identify faults such as warping, missing intumescent strips, damaged frames or malfunctioning self-closers. British Standards like BS 8214 guide correct installation and maintenance, ensuring that doors continue to provide their rated protection.
Neglecting maintenance can result in serious consequences. Beyond the risk to life and property damage, enforcement action may include fines, notices and prosecutions under the Fire Safety Order.
Practical considerations for different building types
- Residential flats: Flat entrance doors must prevent fire and smoke from spreading into communal areas. Inspections are essential and residents should be informed about fire door signage and the importance of keeping doors closed.
- Offices and commercial buildings: Fire doors protect escape routes and habitable rooms. Regular checks and a robust fire safety strategy are critical.
- Public buildings: Due to higher occupancy and variable risk profiles, fire doors must be maintained meticulously. Fire risk assessments can often identify additional requirements such as higher fire ratings, stricter inspection intervals and control of the premise’s responsibilities.
Stay informed
Understanding internal fire door regulations is essential for anyone responsible for the safety of people and property. Legal compliance, combined with professional inspections and maintenance, ensures fire doors function as intended, slowing fire, protecting escape routes and supporting safe evacuation in the event of a fire.
