Fire doors are a critical element of passive fire protection in residential buildings. They form part of the compartmentation strategy, containing fire and smoke within defined areas and protecting escape routes. The Fire Safety (England) Regulations 2022 introduced specific, mandatory requirements for fire door inspection in residential buildings, placing clear obligations on the responsible person to ensure that all fire doors are maintained to a compliant standard.
The Fire Safety (England) Regulations 2022, which came into force on 23 January 2023, introduced the following fire door inspection requirements for residential buildings in England. For buildings over 11 metres in height, the responsible person must carry out annual checks of all flat entrance doors. For buildings over 18 metres, flat entrance doors must be inspected annually and all communal fire doors (including those to stairways, lobbies, plant rooms and service cupboards) must be inspected quarterly.
These inspections must be carried out by a competent person. While the regulations do not prescribe a specific qualification, the responsible person must be satisfied that the inspector has the knowledge, skills and experience to carry out the inspection to a competent standard. Using a qualified fire door inspector with relevant accreditation is strongly recommended.
A compliant flat entrance fire door in a residential building should achieve a minimum of FD30S performance — 30 minutes of fire resistance with smoke seals. The door must be self-closing, fitted with intumescent strips and cold smoke seals, hung on at least three hinges, and have gaps between the door and frame of 2 to 4mm (with a maximum of 8mm at the threshold). The door leaf, frame, glazing (if any) and all hardware must be compatible and tested together as a complete doorset. Third-party certification from an accredited body provides the strongest evidence of compliance.
The inspector checks the door leaf for damage, warping, delamination, holes and signs of alteration. The frame is assessed for integrity, correct fixing and alignment. Any damage that could compromise the fire resistance of the door or frame is recorded as a deficiency. The inspector also checks that the door has not been modified in a way that invalidates its fire performance, such as cutting for cat flaps or letter boxes without fire-rated protection.
Intumescent strips expand in heat to seal the gap between the door and frame, preventing fire passage. Cold smoke seals prevent smoke spreading through gaps at ambient temperature. The inspector checks that both are present, correctly positioned, undamaged and of the correct specification. Missing, damaged or painted-over seals are a very common finding and render the door non-compliant.
Fire doors in residential buildings must be self-closing. The inspector checks that the self-closer is present, functional and of adequate strength to close the door fully from any open position into its frame. Missing or broken self-closers are one of the most common fire door deficiencies. Doors that are wedged or held open (unless with a hold-open device linked to the fire alarm) represent a serious compartmentation breach.
Gaps between the door leaf and frame should be 2 to 4mm on the hinge side, lock side and top edge. Excessive gaps allow fire and smoke to bypass the seals. Glazed panels must use fire-rated glass in fire-rated beading, and the aperture size must comply with the door's tested specification. Non-fire-rated glass in a fire door is a critical deficiency.
For managing agents and RMCs responsible for multiple buildings, a structured fire door inspection programme is essential. This should schedule annual inspections of all flat entrance doors, quarterly inspections of communal fire doors in buildings over 18 metres, and maintain a database recording the location, type, condition and compliance status of every fire door in the portfolio. The programme should integrate with the building's fire risk assessment and any Building Safety Act obligations.
Where inspection identifies non-compliant doors, the responsible person must develop a prioritised remediation programme. Minor deficiencies such as missing seals, broken self-closers or damaged signage can often be remedied quickly. More significant issues such as non-certified doors, excessive gaps, warped leaves or doors that cannot be upgraded may require full door replacement. The remediation programme should be costed, prioritised by risk and implemented within reasonable timescales. Records of all inspections and remedial works should be maintained as evidence of compliance.
Buildings over 11 metres: flat entrance doors annually. Buildings over 18 metres: flat entrance doors annually and communal fire doors quarterly. These are minimum frequencies under the Fire Safety (England) Regulations 2022. More frequent inspection may be appropriate for buildings with known issues or high wear.
The inspector checks the door leaf, frame, intumescent strips, smoke seals, self-closing device, gaps, hinges, glazing, signage and overall condition. They also verify certification and assess whether the door has been modified in ways that compromise its fire performance.
The responsible person under the Fire Safety Order — typically the freeholder, managing agent or RMC — is responsible for fire doors in common parts and for ensuring flat entrance doors are checked at the required frequency. Individual leaseholders are responsible for the fire performance of their flat entrance door.
Non-compliant doors should be recorded with specific deficiencies noted. Minor defects can often be remedied quickly. Significant failures may require door replacement. The responsible person should develop a prioritised remediation programme addressing the most critical deficiencies first, with records maintained as evidence of compliance.
