What Happens If You Fail
a Fire Door Inspection?

Published 12 April 2026 • DE Fire Compliance • 5 min read

Most buildings fail their first fire door inspection. That isn’t necessarily a crisis — but it does mean you need to understand the findings, prioritise remedial works, and demonstrate that you’re taking compliance seriously.

This guide covers what a failed inspection actually means, the severity ratings used, what remedial actions are required, and what happens if you ignore the results.

What Does “Failing” a Fire Door Inspection Mean?

When a fire door is inspected against BS 8214:2016, each door is assessed individually. There’s no pass or fail for the whole building — each door gets its own status. A single fire door can fail for a range of reasons, from minor issues to critical defects.

Common reasons fire doors fail inspections include:

• Gaps between the door and frame exceeding 3mm
• Missing or damaged intumescent strips and cold smoke seals
• Self-closing devices that don’t fully close the door into the frame
• Missing fire door signage or certification labels
• Damaged door leaves, splits, or holes
• Incorrect or non-fire-rated glazing
• Fewer than three hinges, or non-fire-rated hinges
• Letterboxes or cat flaps that compromise fire integrity

Understanding Severity Ratings

A professional fire door inspection report will categorise each defect by severity. While exact terminology varies between inspectors, most reports use a system like this:

Severity	What It Means	Action Required
Critical	The door cannot perform its fire safety function. Compartmentation is compromised.	Immediate remediation or replacement
Major	Significant defects that reduce fire performance. The door may not contain fire for its rated duration.	Remediation within 4–6 weeks
Minor	Defects that should be addressed but don’t immediately compromise fire safety.	Remediation at next scheduled maintenance
Advisory	Best practice recommendations or cosmetic issues.	Recommended but not urgent

Key point: A critical or major defect means the fire door is not functioning as intended. In a fire, it may not contain smoke and flame for the rated period — typically 30 or 60 minutes. This directly endangers occupants and compromises escape routes.

What Remedial Works Are Typically Needed?

The good news is that most fire door defects can be fixed without replacing the entire door. Common remedial works include:

• Intumescent strip and seal replacement — strips that are missing, painted over, or degraded can be replaced in situ
• Gap adjustment — rehinging, planing, or adjusting the frame to bring gaps within the 3mm tolerance
• Self-closer replacement — fitting a new overhead closer that pulls the door fully into the frame
• Hinge replacement — upgrading to three fire-rated hinges per door
• Signage — adding “Fire Door Keep Shut” or “Fire Door Keep Locked” signs
• Full door replacement — required when the door leaf itself is compromised, uncertified, or beyond economic repair

A good inspector will scope remedial works in the report, giving you a clear list of what needs doing, door by door, so you can price and schedule the work.

What If You Ignore a Failed Inspection?

Ignoring fire door defects is a serious risk — both legally and practically.

Legal consequences

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must maintain fire safety measures in working order. If your fire doors have been inspected and found defective, you’re now on notice. Failing to act can lead to:

• Enforcement notices from the fire and rescue authority, with a deadline for remediation
• Prohibition notices restricting use of the building until defects are resolved
• Prosecution for serious non-compliance, with unlimited fines and up to two years’ imprisonment

Insurance implications

If a fire occurs and your insurer discovers that fire doors were inspected, found defective, and not repaired, your claim could be reduced or rejected. Fire door compliance is increasingly a condition of building insurance policies.

Civil liability

If someone is injured or killed in a fire and failed fire doors contributed to the outcome, the responsible person faces personal civil liability. Post-Grenfell, courts have taken an increasingly hard line on fire safety negligence.

How Quickly Do You Need to Act?

This depends on the severity of the findings:

• Critical defects: Immediately. Consider taking the door out of service or implementing interim measures (e.g., a fire warden) until the door is repaired or replaced.
• Major defects: Within 4–6 weeks. Document your remediation plan and start scheduling works.
• Minor defects: At the next scheduled maintenance window. Log the findings and track progress.

The key is demonstrating that you’ve received the report, understood the findings, and taken proportionate action. Keep records of everything — the inspection report, remedial quotes, completion dates, and follow-up inspections.

What Should You Do After a Failed Inspection?

1. Review the report carefully. Understand which doors failed, the severity of each defect, and the recommended remediation.
2. Prioritise critical and major defects. These need action first.
3. Get remedial quotes. A competent fire door contractor can usually fix most issues on-site.
4. Schedule the work. Keep a documented programme of remediation with target dates.
5. Re-inspect after remediation. Once works are complete, a follow-up inspection confirms the doors now comply.
6. Keep records. Store the original report, remedial invoices, and follow-up inspection results. These are your evidence of compliance.

Most Buildings Fail — That’s Normal

If your building has never had a professional fire door inspection, expect defects. It’s extremely common, even in well-maintained buildings. The important thing isn’t whether you fail — it’s what you do about it.

A failed inspection is actually the first step toward compliance. You now have a documented record, a clear action plan, and a defensible position if the fire authority ever asks what you’re doing about fire door safety.
