Top 10 Common Fire Door Inspection Issues Found in UK Commercial Properties
Fire doors are one of the most important fire safety features in any commercial building. When they work properly, they help contain fire and smoke, protect escape routes, and save lives. When they fail, the consequences can be severe.
Despite their importance, fire door inspections across the UK frequently uncover the same issues time and time again. Many of these faults are easily preventable, yet they continue to put people and property at risk.
This guide outlines the ten most common fire door inspection issues found in UK commercial properties and explains why addressing them is critical for compliance and safety.
Why Fire Door Inspections Matter
Fire doors are designed to resist fire and smoke for a set period, usually 30 or 60 minutes. To achieve this, every component must work together as intended.
Under UK fire safety legislation, Responsible Persons must ensure that fire doors are:
-
Suitable for their location
-
Correctly installed
-
Properly maintained
-
Regularly inspected
Failing to maintain fire doors can result in enforcement action and serious safety breaches.
1. Fire Doors Wedged Open
One of the most common and dangerous issues is fire doors being wedged or propped open.
This completely defeats the purpose of the door by allowing fire and smoke to spread unchecked. While it may seem convenient for ventilation or movement, wedging open a fire door puts everyone in the building at risk.
2. Damaged or Missing Intumescent Seals
Intumescent seals expand when exposed to heat, sealing gaps around the door to prevent fire and smoke spread.
Inspections frequently find:
-
Missing seals
-
Painted-over seals
-
Damaged or incorrectly fitted seals
Without effective seals, even a well-built fire door can fail in a fire.
3. Excessive Gaps Around the Door
Fire doors must have gaps within specific tolerances, usually around 3–4mm.
Common issues include:
-
Gaps that are too wide
-
Uneven gaps due to poor installation
-
Warped doors or frames
Excessive gaps allow smoke to pass through quickly, compromising escape routes.
4. Incorrect or Missing Fire Door Closers
Fire doors must close fully and latch without assistance.
Inspections often reveal:
-
Broken or leaking closers
-
Doors that do not fully close
-
Closers removed due to noise complaints
If a fire door does not close properly every time, it cannot perform its safety function.
5. Non-Fire-Rated Door Hardware
Fire doors rely on compatible, fire-rated components to perform correctly.
Common hardware issues include:
-
Non-compliant hinges
-
Inappropriate locks or latches
-
Missing or incorrect signage
All components must be suitable for fire door use and installed correctly.
6. Door Leaf or Frame Damage
Physical damage to a fire door can significantly reduce its fire resistance.
Inspections frequently identify:
-
Cracks or splits in the door leaf
-
Holes caused by impact damage
-
Deterioration due to moisture
Even minor damage can compromise the integrity of the door.
7. Inappropriate Modifications
Fire doors are often altered after installation without proper consideration.
Common unauthorised changes include:
-
Cutting new apertures
-
Adding non-approved vision panels
-
Over-trimming doors to fit altered frames
These modifications can invalidate the door’s fire rating.
8. Missing or Incorrect Certification
Fire doors should be clearly identifiable as fire-resisting doors.
Inspections often find:
-
Missing certification labels
-
Painted-over identification marks
-
Inability to confirm door rating
Without clear identification, it is difficult to ensure the correct level of protection is in place.
9. Poor Installation Standards
Even compliant fire doors can fail if they are poorly installed.
Common installation issues include:
-
Incorrect frame fixings
-
Inadequate fire stopping around frames
-
Misaligned doors
Poor installation is a major contributor to fire door failure.
10. Lack of Regular Inspections and Records
Perhaps the most common issue of all is the absence of a structured inspection and maintenance regime.
Responsible Persons are expected to:
-
Carry out regular visual checks
-
Arrange formal inspections at appropriate intervals
-
Keep records of inspections and repairs
Missing documentation can be just as problematic as physical defects during enforcement action.
Fire Door Inspections and Legal Responsibilities
UK fire safety law requires Responsible Persons to take reasonable steps to ensure fire doors remain effective.
Fire door inspections support compliance by:
-
Identifying defects early
-
Prioritising remedial works
-
Providing documented evidence of maintenance
Regular inspections reduce risk and demonstrate proactive management.
How Often Should Fire Doors Be Inspected?
Best practice guidance recommends:
-
Routine visual checks by building staff
-
Formal inspections at least every six months
-
More frequent checks in high-use areas
Buildings such as hospitals, care homes, and busy commercial premises may require more frequent inspections.
The Importance of Competent Inspectors
Fire door inspections should be carried out by competent individuals who understand:
-
Fire door construction
-
Relevant standards
-
Installation requirements
Competent inspections provide clear, actionable reports that help Responsible Persons maintain compliance.
Protecting Lives and Property
Fire doors are a critical line of defence in the event of a fire. Addressing common inspection issues promptly helps protect escape routes, slow fire spread, and give occupants vital time to evacuate.
For UK commercial property owners and managers, regular fire door inspections are not just good practice – they are essential for safety and compliance.
