BS 8214:2026: what has changed?
Short answer: BS 8214:2026, published in March 2026, replaced BS 8214:2016. It covers fire-resisting and smoke control doors as a complete system across timber, steel, glazed metal and composite types, adds guidance for metal and composite doors, clarifies smoke seal advice in line with BS 9991, and gives clearer guidance on sealing frame-to-wall gaps.

- Clearer frame-to-wall sealing guidance
What is BS 8214?
BS 8214 is the British Standard code of practice for fire-resisting and smoke control doors. It gives recommendations on specifying, installing and maintaining fire doors so that they perform in use as they did in their fire test.
When was BS 8214:2026 published?
The revised standard was published in March 2026 and replaced BS 8214:2016, which has been withdrawn.
What are the main changes?
- Wider scope: fire doors are treated as a complete system, whether supplied as assemblies, doorsets or kits, across timber, steel, glazed metal and composite doors.
- Metal and composite doors: new guidance fills a gap left by the earlier, timber-focused edition.
- Evidence-led: the standard sets out what supporting evidence is needed for each door construction rather than prescribing every detail.
- Smoke control: clearer advice on seals and under-door gaps, aligned with BS 9991.
- Frame-to-wall sealing: improved guidance on sealing the gap between frame and structure, with examples of acceptable materials.
- Regulatory alignment: reflects UKCA and CE marking and duties under the Building Safety Act 2022 and Fire Safety Act 2021.
What does it mean for building owners?
Expect inspectors and installers to ask for evidence: what the door is, what it was tested with and what alterations it can accept. Keeping product evidence and installation records for every door will make inspections quicker and repairs more straightforward.
Do existing doors need replacing because of the new standard?
No. A code of practice does not make existing compliant doors non-compliant. It changes how doors should be specified, installed and maintained from now on, and gives inspectors a clearer reference.

What is the difference between a fire door and a fire doorset?
A fire door often means just the leaf. A doorset is the complete assembly, leaf, frame, seals and hardware, tested and supplied together. Doorsets remove much of the guesswork from installation and are usually the better choice for replacements.
What do FD30 and FD60 mean?
They describe how long the door is designed to resist fire in a test: 30 or 60 minutes. An S after the rating, such as FD30S, means the door also controls the passage of cold smoke.
Is expanding foam acceptable around a fire door frame?
Only a fire-rated foam with evidence for that use and gap size. Ordinary expanding foam is not suitable. BS 8214:2026 lists acceptable approaches such as suitable mastics, foams and stone wool.
Do you need to remove architraves?
Often, yes. The frame gap is usually hidden behind the architrave, so we remove and refit it to inspect and seal properly.
