Fire Door Inspection: BS 8214 Compliance Checklist UK

Quick Answer: Fire doors (FD30, FD60, FD90, FD120) must be inspected against BS 8214:2016 and the Fire Safety (England) Regulations 2022 in multi-occupancy buildings. Inspection focuses on integrity (intumescent strips, gaps, hardware, closer, glazing), labelling, and installation quality. Inspections required at least annually for high-risk premises (flats above 11m), six-monthly for flat entrance doors. Cost £15–£40 per door for routine inspection; £80–£250 for FDIS-certified detailed inspection.

Summary

Post-Grenfell, fire door compliance moved from a quiet area of building safety to one of the most regulated, scrutinised, and litigated. The Fire Safety (England) Regulations 2022 made flat entrance door inspections mandatory in multi-occupancy buildings above 11m. The Building Safety Act 2022 added long-term accountability for the "Accountable Person" — and downstream of them, the inspectors and trades who certified the doors.

Fire doors are not just doors. They're certified integrity assemblies — door leaf, frame, intumescent strips, smoke seals, hinges, closers, ironmongery, glazing, and signage — that must be installed and maintained as a system. Replacing a single hinge with a non-fire-rated alternative voids the entire assembly's certification.

This article covers the inspection standards, what trade inspectors check, what to do when defects are found, the FDIS (Fire Door Inspection Scheme) qualification, and how to offer fire door inspection as a billable service or refer it on responsibly.

Detailed Guidance

The legal framework

Three main pieces of legislation drive fire door inspections:

Regulatory Reform (Fire Safety) Order 2005 — The Responsible Person duty. Applies to all non-domestic premises and common parts of HMOs/flats. Requires fire risk assessment which includes fire doors.

Fire Safety (England) Regulations 2022 — From January 2023, in residential buildings over 11m (typically 4+ storeys):

Building Safety Act 2022 — For "higher-risk buildings" (18m+ or 7+ storeys), the Accountable Person must maintain a Safety Case demonstrating ongoing fire compliance, including doors.

What an inspector actually does

A typical fire door inspection takes 10–25 minutes per door:

  1. Identify the door — Location, plot number, last inspection date
  2. Check labels and certification — Manufacturer mark visible? FD rating? Certification body (BWF-CertiFire, IFCC, Warringtonfire etc)?
  3. Visual inspection — Door leaf for damage, swelling, repairs
  4. Frame inspection — Sound, properly fixed, no gaps
  5. Gap measurement — Use 2mm and 4mm gauges around perimeter
  6. Intumescent strip — Continuous, correct type, not painted over, not damaged
  7. Smoke seal — Continuous, not damaged
  8. Hinges — Count (3 minimum), check fire-rating mark, screw tightness
  9. Latch/lock — Operate, check for fire rating
  10. Closer — Open door 5°, 30°, 90°. Verify closes fully from each.
  11. Glazing (if present) — Fire-rated glass mark, intumescent bead intact
  12. Signage — Present, visible, legible
  13. Photograph defects — Each non-compliance with image
  14. Issue report — Pass / Fail with defect schedule and recommended action

The FDIS qualification

The Fire Door Inspection Scheme (run by FIS — Fire Industry Sector body) certifies inspectors at:

Training: ~5 days classroom + online + 2-day site assessment. Cost £1,000–£1,800. Renewal every 3 years.

FDIS-certified inspectors carry credibility with fire safety officers, insurance companies and tribunals. For high-stakes inspections (high-rise residential, public buildings, schools), FDIS certification is increasingly mandatory.

For domestic landlords / small HMOs, non-certified competent inspectors are accepted if the Responsible Person can demonstrate the inspector is "competent" — a documented training record and trade qualifications often suffice.

Defects — what they mean

Critical defects (immediate action):

These require IMMEDIATE remediation. Inform Responsible Person same day. Don't leave the building "open" overnight without escalation.

Major defects (action within 28 days):

Minor defects (next maintenance cycle):

Working as a tradesperson — what you CAN'T do

Carpentry trade competence does NOT make you a fire door inspector. Specifically:

These rules surprise carpenters who've worked on fire doors for years. The certification system is unforgiving.

When to refer

Refer to FDIS-certified inspector or fire door specialist when:

For small (sub-10 door) low-rise inspections, competent carpenter/joiner can carry out checks with appropriate training and clear scope documentation.

Common installation faults

These are the most-found defects in trade installations:

  1. Wrong gap at threshold — Door installed too high above floor. Threshold gap >8mm = fail. Need to drop door or add threshold strip.
  2. Painted-over intumescent — Painter rolls paint over intumescent. Strip can't expand correctly. Strip and replace.
  3. Wrong hinges — Carpenter uses standard hinges. FD30 needs Grade 13 fire-rated. Replace.
  4. Missing intumescent — Carpenter forgets to fit strips when machining frame. Must rebate and fit.
  5. Frame not packed — Frame fixed with shim packers but voids not filled with intumescent mastic. Must fill.
  6. Closer too weak — Closer doesn't close door against latch from 5°. Replace.
  7. Non-fire-rated viewer/letterbox — Standard letterbox without intumescent insert. Replace.

Quoting fire door inspections

Pricing models:

Volume work (housing association portfolios of 500+ doors) commands lower per-door rates but higher overall fees and longer-term contracts.

Worked example — 24-flat block, ground +4 storeys

Total annual inspections:

At £25 average per door = £3,100 annual contract value. With pricing flexibility, this can be a £4,500–£6,000 annual contract per block. Three blocks = £15,000 annual recurring revenue from one customer.

Frequently Asked Questions

Can I make a normal door into a fire door?

No — fire doors are tested assemblies, certified by manufacturer. A normal door cannot be retrofitted with intumescent strips and "made" fire-rated. The leaf construction (core material), frame, and overall assembly must all be tested. Buy a certified fire door.

How do I tell what FD rating a door is?

Look for the manufacturer's certification label, typically on the top edge or hinge edge of the door. Label shows manufacturer name, FD rating (FD30, FD60, etc), and certification body. If label is missing or painted over, treat the door as uncertified — it cannot be considered fire-rated without proof.

Are fire doors needed in private houses?

Generally no, except: doors from integral garage to dwelling (Part B 2025 requires FD30s); doors enclosing internal stairs in houses of 3+ storeys (Part B); and some HMOs (House of Multiple Occupation) which have specific fire door requirements.

What's the difference between FDIS and BAFE inspection?

FDIS is fire door specific — for inspecting and certifying individual doors. BAFE schemes (SP203, SP205) cover wider fire systems — sprinklers, alarms, suppression, AND active fire protection. For door-only work, FDIS is the relevant certification. For broader fire safety surveys, BAFE.

Can I paint a fire door?

Yes, but carefully. Standard intumescent strips can be painted but only with paint that won't impede expansion (light coats, water-based). Heavy paint build-up over intumescent strips fails. Best practice: mask the intumescent before painting; remove and replace strips if heavily painted-over.
