Why Fire Door Inspections Are Legally Required
Under the Fire Safety (England) Regulations 2022, fire door inspections are not optional — they are a legal obligation for most landlords and property managers in London. A fire door that looked compliant when installed can become non-compliant through normal use, damage or building movement within months.
UK Legal Inspection Frequencies — Buildings over 11 metres: communal fire doors every 3 months, flat entrance doors every 12 months. HMOs: annual inspection strongly recommended. All properties: immediately after any fire, flood or structural work.
What Our Inspection Service Includes
This page now works as a service page, not just a guide. A proper fire door inspection in London should end with something useful: a clear record of what was checked, what failed, what can be repaired and what may need replacing.
- On-site inspection of the door leaf, frame, closer, hinges, seals, gaps, glazing and signage
- Photo-backed findings so landlords, agents and block managers can see the defects clearly
- Written report with practical notes rather than vague pass/fail language
- Remedial advice showing what can be adjusted, repaired or replaced
- Follow-on quotation for remedial work if you want one supplier to inspect and fix
Most clients want three things: a clear list of defects, supporting photos, and a practical next step. That may be an adjustment, a hardware upgrade, a new closer, a seal replacement or a full door-and-frame replacement if the opening is fundamentally wrong.
Who Uses This Service
We carry out fire door inspections for London landlords, HMOs, flat blocks, freeholders, RTMs, managing agents and private owners who need clarity before ordering replacements. Some clients book us after a council request, some before licensing, and some because they want a second opinion before spending money on new doors.
Turnaround And Next Steps
For most London enquiries, we can advise quickly, arrange an inspection slot, and then issue a written summary with the findings and the likely remedial route. If the inspection shows urgent defects, we can also advise on priority actions first rather than making you wait for a full replacement programme.
Do not replace doors blindly after a failed inspection. Some failures are hardware, closer, seal or gap issues rather than full replacement jobs. A good inspection should help you avoid overspending as well as help you avoid under-specifying the opening.
The Complete Fire Door Inspection Checklist
Use this checklist for every fire door in your London property:
- Certification label present — look for CERTIFIRE, BWF or BM TRADA label on top edge of door
- Door closes fully — must latch completely with no gaps, without being held
- Self-closer working — door must return and latch from any open position
- Gap around door edges — maximum 3mm on sides and top, 4mm at threshold
- Intumescent strips intact — no gaps, splits or sections missing
- Smoke seals present and intact — brush or rubber seals around full perimeter
- Minimum 3 hinges fitted — all fire-rated, no loose screws
- No damage to door leaf — no holes, splits, repairs or glazing changes
- Frame in good condition — no warping, gaps between frame and wall
- Glazing fire-rated — if door has glass, must be fire-rated glass only
- Signage present — "Fire Door Keep Shut" sign on both sides
- No wedges or props — door must never be propped open
Common Failures Found During Inspections
1. Door Not Closing Properly
The most common failure. Caused by a faulty self-closer, building settlement, or door warping. A fire door that doesn't fully close provides zero fire protection. Doorz can adjust, repair or replace on the same visit.
2. Missing Or Damaged Intumescent Strips
Strips can be damaged by cleaning, painting or normal use. Without intact strips, fire and hot gases pass through the frame gap within minutes. This is a fail — immediate action required.
3. Incorrect Gap Tolerance
Gaps over 3mm around the door allow smoke through. Gaps under 1mm cause the door to bind and not close properly. Both are a fail. Requires rehinging or frame adjustment.
4. No Certification Label
Without a visible certification label, you cannot prove the door is fire-rated. Common in older properties where doors were fitted before certification labelling was standard. These doors should be replaced.
What Happens If You Fail An Inspection?
If a fire door fails inspection you have a legal obligation to remediate immediately — particularly in HMOs and buildings over 11 metres. Continued occupation with known fire door defects can result in:
- Prohibition notice — tenants ordered to vacate
- Unlimited fine
- Potential criminal prosecution
- Invalidated building insurance
- HMO licence revoked
