Fire Door Regulations & Requirements in the UKStandards, Certification & What Is Changing

There is no single document called "the fire door regulations". UK fire door requirements arise from a combination of fire safety legislation, building regulations, Approved Documents, fire risk assessment duties, product performance standards, installation requirements, maintenance requirements and certification evidence. In England the key instruments are the Regulatory Reform (Fire Safety) Order 2005, the Fire Safety Act 2021, the Fire Safety (England) Regulations 2022, the Building Regulations and Approved Document B.

Legal requirements depend on the building, its use and where the door is located. Generally, fire doors must be suitable for their intended purpose, correctly specified as complete doorsets, installed in line with the relevant evidence, maintained in efficient working order, and supported by appropriate test evidence and certification. Responsible Persons must also carry out fire risk assessments and, in certain residential buildings, meet the routine fire door checking duties in the Fire Safety (England) Regulations 2022.

Regulation 10 applies to buildings containing two or more domestic premises with common parts. For relevant buildings where the top storey is more than 11 metres above ground level, it requires communal fire doors to be checked at least every 3 months and flat entrance doors to be checked at least every 12 months on a best-endeavours basis. It applies in England and does not apply identically across the whole UK.

There is no single UK-wide frequency for every door. Under the Fire Safety (England) Regulations 2022, in qualifying residential buildings above 11 metres, communal fire doors are checked at least quarterly and flat entrance doors at least annually. All fire doors should also be maintained in efficient working order as part of the fire risk assessment. The government guidance treats these routine checks as distinct from a detailed technical assessment of fire-resistance suitability.

England is moving away from BS 476 national classifications toward the European classification framework referenced through BS EN standards. References to BS 476 for reaction to fire and roofs were removed from Approved Document B from 2 March 2025, and references to BS 476 for fire resistance are due to be removed on 2 September 2029, subject to transitional arrangements. This does not mean existing BS 476 doors automatically become non-compliant.

The Government’s current timetable removes references to BS 476 fire-resistance classifications from Approved Document B on 2 September 2029, subject to transitional provisions for qualifying projects. After that date the EN classification framework becomes the sole route of specification within ADB for fire-resistance classifications.

BS EN 1634-1 is the European standard associated with fire resistance testing of door and shutter assemblies. It is a test method that produces evidence; it is not itself the classification standard. Test evidence generated under EN 1634-1 feeds into classification under EN 13501-2.

BS EN 13501-2 is the European classification framework used to classify the fire resistance and smoke-control performance of construction products and elements, including doorsets, based on relevant test evidence. It uses coded performance criteria such as integrity (E), insulation (I) and smoke (S). It is the classification standard, not the fire test itself.

BS 476 is the historical UK national testing and classification route. EN 13501-2 is the European classification framework that uses BS EN test methods such as EN 1634-1. The Government is moving Approved Document B away from BS 476 national classes toward the EN classification framework, with fire-resistance references due to be removed from ADB on 2 September 2029 subject to transitional arrangements.

Certifire is a third-party fire certification scheme operated by Warringtonfire. Its register lists certified products and systems together with their field of application, so specifiers and enforcement authorities can check suitability for intended use. Certification includes ongoing factory auditing. Certifire is a certification scheme, not a government regulator.

BM TRADA operates Q-Mark third-party certification schemes covering fire door and doorset manufacturing and processing, including schemes based on EN 13501-2. Q-Mark provides assurance within the scope of the relevant certification scheme through ongoing auditing and traceability. It is not compulsory in every project, but third-party certification provides additional assurance of consistency and conformity.

No. There is no universal requirement that every fire door must hold Certifire certification. Requirements depend on the building, the applicable guidance and any project-specific specification. Third-party certification such as Certifire or Q-Mark provides additional assurance of consistency and conformity, but whether it is required depends on the specific circumstances and should be verified against current guidance.

Not automatically. Hinges, closers, locks, seals, glazing and frames may all form part of the evidence supporting a particular doorset configuration. Because two components are individually fire-rated does not mean they can be substituted for one another. The field of application is controlled by the relevant EXAP and classification evidence, so substitutions should be checked against the tested configuration.

Not necessarily. A change in standards does not automatically mean every existing door must be replaced. Government guidance contains transitional provisions, and existing evidence may remain relevant under applicable transitional arrangements. Whether a particular door needs action depends on its condition, location, the applicable requirements and any transitional rules that apply to the project.

Useful records include door identification and reference, location, rating/classification, manufacturer, door leaf and frame specification, glazing, hardware, installation information, test evidence, classification report, certification, installation records, inspection records, maintenance history, remedial work, photographs and relevant certificates. The exact evidence required depends on the door, the project and the applicable requirements.

Manufacturers should understand how their existing product evidence maps to the EN-based environment, including EN 13501-2 classification, EN 1634 test evidence, EXAP and classification reports, component traceability, manufacturing controls, third-party certification, documentation, product marking and supply-chain evidence. Existing evidence may remain relevant under transitional arrangements, so manufacturers should plan rather than assume every product must be immediately retested.
