Fire Door Regulations Flats must meet the Fire Safety Order and Fire Safety (England) Regulations 2022, with doorsets installed to BS 8214 and tested to EN 1634/BS 476. We guarantee self‑closers to BS EN 1154 operate reliably, gaps are typically 2–4 mm at head/jambs (≤3 mm preferred) and controlled at thresholds, and smoke/intumescent seals are intact. Mandatory blue “Fire door keep shut/locked” signs must be on both sides at eye level. We also cover inspections, defects, and evidence landlords often miss.
Key Takeaways
- Flat entrance doors to common areas must be fire-resisting, smoke-sealed doorsets with compliant self-closers per BS EN 1154/1155 and maintained operational.
- Gaps at head and jambs should generally be 2–4 mm (not exceeding 3 mm for many systems); thresholds typically ≤10 mm unless smoke-sealed per manufacturer.
- Self-closers must fully close and latch the door from any position; adjust or replace immediately if slamming, dragging, or failing to latch.
- Mandatory blue “Fire door keep shut/locked” signs must be on both sides at eye level, clearly visible, using standard wording and symbols.
- Regular checks: daily/weekly for obvious defects, monthly closer/latch tests, and six-monthly competent inspections with documented records and unique door IDs.

Why Fire Doors Matter in Flats
Although they’re easy to overlook, fire doors are the primary passive fire protection in a block of flats, controlling smoke and flame spread, preserving compartmentation, and protecting escape routes. We stress fire door importance because performance relies on certified doorsets, compatible hardware, and correct installation. If a leaf, frame, intumescent seal, or self-closer is compromised, the door won’t achieve its rated integrity or smoke control, reducing available safe egress time.
We also prioritise tenant awareness. Residents must keep doors shut, never wedge them open, report damage, and recognise compliant signage. Routine inspections should verify gaps, latching, self-closing action, and seal continuity. Under safety regulations, responsible persons must manage maintenance, document checks, and rectify defects promptly. Vigilance keeps compartmentation intact and evacuation routes tenable.
Key Legal Framework and Standards
Because compliance rests on knowing exactly what’s required, we anchor fire door strategy to the UK’s core legal duties and referenced standards. For flats, the Regulatory Reform (Fire Safety) Order 2005 and the Fire Safety Act 2021 extend duties to flat entrance doors, common parts, and structure. The Fire Safety (England) Regulations 2022 mandate routine checks in high‑rise and quarterly checks in buildings with common areas.
We specify to BS 8214 (installation), BS 9991/BS 9999 (fire safety design), EN 1634/BS 476 (fire resistance/door set testing), and EN 1154/EN 1155 (self‑closers/hold‑open). Third‑party certification and CE/UKCA marking evidence performance. We track legal updates and address compliance challenges with documented inspections, maintenance, and change control. Expect enforcement actions where records, compartmentation integrity, or signage fall short.
Responsibilities: Landlords, Agents, and Residents
With the legal framework defined, we assign clear duties across those who own, manage, and occupy the building. We treat landlord obligations, agent duties, and tenant rights as interlocking controls that keep doors compliant and effective. Landlords set policy, fund works, and evidence compliance; agents operationalize inspections and maintenance; residents cooperate, report defects, and avoid interference.
Clear, interlocking duties ensure compliant, effective doors: landlords lead, agents execute, residents cooperate and report.
- Landlords: commission competent fire risk assessments, maintain self-closers, seals, and signage, keep records, and act on defects within defined timescales.
- Managing agents: schedule inspections, verify installer competence, control key access, log remedial actions, and issue notices when doors are compromised.
- Residents: preserve door integrity, permit access for inspections, report damage immediately, and attend safety training where provided.
We document responsibilities in tenancy packs, management agreements, and house rules, ensuring accountability and audit trails.
Where Fire Doors Are Required in Blocks of Flats
Once we map a block’s layout and evacuation strategy, we can locate where fire-resisting doors are mandatory under the Building Regulations and the Fire Safety Order. We prioritise fire door placements to protect common parts forming emergency exit routes and to compartment floors and risers. Flat entrance doors opening onto common corridors, lobbies, or stairwells must be fire-resisting and smoke-sealed. Doors enclosing protected stair cores, firefighting lobbies, lift lobbies, plant rooms, bin stores, meter rooms, and service risers also require rated sets.
We guarantee doorsets between car parks and residential circulation routes are appropriately rated. In maisonettes, internal doors to protected routes leading to final exits may be specified. Where a stay-put strategy applies, robust compartmentation via compliant doors at flat entrances is critical to flat safety measures and overall means of escape effectiveness.
Self-Closing Devices: Types and Performance Requirements
Although a door leaf may be perfectly rated, it only protects life if it closes reliably and latches. We specify self closing mechanisms that comply with BS EN 1154/1155 and are suitable for the door mass, width, and location.
Options include surface-mounted automatic closers, concealed cam-action units for low opening force, and electromagnetic hold-open or swing-free devices released by the fire alarm per BS 7273-4. All door hardware must be compatible and CE/UKCA marked.
Fire doors save lives only if they close and latch. Specify compliant, compatible, and reliably releasing self-closing systems.
- Types: overhead rack-and-pinion, cam-action concealed, floor springs, and electrically released units for communal areas.
- Performance: consistent closing force against seals, reliable latching from any open angle, and endurance per Grade 1 test cycles.
- Suitability: power size selection (EN 1154), temperature stability, corrosion resistance, and accessibility compliance.
Checking and Adjusting Closing Speed and Latching
Before signing off any fire door, we verify and, if necessary, adjust the closer so the leaf closes under control and latches securely every time. We begin with functional testing: open to 90°, release, and observe sweep, check, and final latch phases. We perform closing speed adjustments so the door neither slams nor stalls, typically achieving a controlled sweep of 5–7 seconds from 90° to 0°. We set the backcheck to prevent damage from forceful opening.
Next, we conduct latching mechanism checks, confirming the latch engages the strike consistently without rebound. We confirm power size is appropriate for door mass and air pressure. As part of self closer maintenance, we inspect fixings, arm geometry, fluid leaks, and seals, then document settings and compliance outcomes.
Gap Tolerances: Head, Jambs, and Threshold Limits
Because fire doors rely on precise clearances to control smoke and fire spread, we verify gaps at the head, jambs, and threshold against the governing standard for the assembly. We apply gap assessment methods using calibrated feeler gauges and certified rulers, documenting tolerances to the millimetre. Typical limits: 2–4 mm at head and jambs, and 3–10 mm at thresholds when paired with an approved drop seal or threshold component. Anything outside tolerance triggers corrective fire door maintenance and compliance testing.
- Measure: Record head/jamb gaps at three points each; check threshold across the sweep.
- Confirm hardware influence: Hinges, latch throw, and closer preload must not distort clearances.
- Verify field conditions: Frame plumb/square, substrate fixings, and seal compression align with listing.
Intumescent Seals and Smoke Seals: What to Look For
While gaps control everyday leakage, seals do the critical work when heat and smoke arrive, so we verify that intumescent and smoke seals match the door-set’s listing and remain serviceable. We confirm intumescent seal types (graphite, sodium silicate, hybrid) align with the certification data, correct size, and activation temperature. We check continuity around head and jambs, hinge and latch interruptions correctly rebated, and no paint bridging.
For cold-smoke control, we assess smoke seal materials typically brush, elastomeric fins, or foam with consistent compression, undamaged carriers, and intact corners. Installation best practices require clean grooves, secure adhesion or mechanical fixing, and no gaps at joints. We reject retrofits that mix untested components, and we document date codes, manufacturer marks, and any heat or water damage.
Mandatory Signage: Locations, Wording, and Materials
With seals verified against the door-set listing, we turn to the mandatory signage that enforces correct use and compliance. We specify blue circular “Fire door keep shut” or “Fire door keep locked” legends to BS 5499/ISO 7010, positioned at eye level on both sides of door leaves serving escape routes and high-risk rooms. Signage visibility must be unobstructed, contrasting with the substrate, and consistent across the premises to pass compliance checks.
- Locations: fit signs on leaf surfaces near the leading edge; add corridor-directional repeats where sightlines are interrupted; include lobby doors and service risers.
- Wording: use standard pictograms and exact text; no improvisation; bilingual only where required by policy.
- Materials: choose rigid photoluminescent or aluminium substrates with tamper-resistant fixings; verify material durability via tested luminance and cleaning resistance.
Ironmongery: Hinges, Locks, Viewers, and Letterplates
Steel and brass components aren’t décor here they’re certified fire door ironmongery that must match the tested door-set. We specify compatible hinge types, lock mechanisms, viewer placement, and letterplates to preserve integrity and performance to the door’s certification. Components require CE/UKCA marking, intumescent protection where tested, and installation per manufacturer data and BS 8214.
| Item | Compliance requirement | Notes |
| Hinges | 3+ grade 13 hinges | Through-bolted; intumescent pads |
| Locks/latches | Fire-rated case | Correct backset; keeps aligned |
| Cylinders | Keyed or thumbturn | Security class; protected length |
| Viewer | Fire-rated, 180° | Centred at eye-level; sealed |
| Letterplate | Fire-rated with flap | Intumescent liner; restrictor |
We maintain tolerances: hinge screw patterns match evidence; spindle and forend dimensions suit the test. Viewer placement must avoid glazing apertures and reinforcement. Lock mechanisms must fail-secure or free-swing as specified by the strategy. Letterplates are prohibited on some doors—verify the door-set data sheet and certification schedule.
Common Defects That Undermine Fire Door Performance
Having specified compatible ironmongery to the tested door-set, we now need to recognise the faults that most often strip a fire door of its certification in practice. We see recurring, high-risk defects that compromise compartmentation and smoke control. Use our inspection checklists to verify door leaf, frame, ironmongery, and seals are all to the tested specification. Apply door maintenance tips that preserve tolerances and closing force while avoiding alterations that void evidence of performance.
- Excessive gaps and misalignment: leaf-to-frame gaps over 3 mm, uneven meeting stiles, warped leaves, or raked thresholds defeat cold-smoke seals.
- Damaged, painted-over, or missing intumescent/smoke seals: discontinuities at corners or hinges are common fire hazards.
- Compromised self-closer/ironmongery: incorrect power setting, missing fixings, non-compatible screws, or unlatched locks prevent reliable self-closing.
Inspection Frequencies, Record-Keeping, and Remedial Actions
Although inspection regimes vary by jurisdiction and risk profile, we should set and document a cadence that meets code and manufacturer guidance: daily/weekly local checks for obvious damage and obstructions, monthly functional checks of self-closing and latching, and 6‑monthly competent person inspections of the complete doorset (leaf, frame, hardware, glazing, seals) with measured gaps and verified compatibility. Our inspection protocols must reference standards, asset registers, unique door IDs, and baseline photographs.
We’ll maintain rigorous documentation practices: dated checklists, measured clearances, closer forces, latch engagement, seal continuity, deviations, and risk ratings. Record temporary mitigations and target dates.
When defects arise, implement corrective measures promptly: adjust or replace closers, hinges, latches, and seals; rectify signage; reinstate intumescent/smoke seals; repair frames; and verify fire-rating compatibility. Re-test, sign off, and archive evidence.
