Fire Door Components & Hardware Requirements (UK)
Fire doors are not assessed as single items. During inspections and Fire Risk Assessments (FRAs), assessors typically look at the entire door assembly, including the door leaf, frame, seals, hinges, closer and other hardware.
This page is for landlords, managing agents and facilities managers who need to understand which fire door components are commonly checked, why they matter, and what issues are typically identified in practice.
Missing, damaged or unsuitable components are among the most common reasons fire doors are recorded as non-compliant.
Why fire door components matter
A fire door only performs properly when its individual parts work together as a complete assembly.
Even where the door leaf itself appears sound, performance can be affected by issues such as:
- excessive gaps
- damaged or missing intumescent seals
- unsuitable hinges
- faulty self-closing devices
- incompatible replacement hardware
- poor adjustment following repair work
This is why inspectors usually assess the whole door set rather than focusing on one visible item.
What inspectors typically look at
When inspecting fire door components and hardware, assessors commonly review:
- door gaps and clearances
- intumescent and smoke seals
- hinges and fixings
- self-closing devices
- latches, locks and other ironmongery
- evidence of damage, wear or unauthorised alteration
They will usually consider not only whether a component is present, but whether it appears suitable, correctly fitted and in serviceable condition.
Common fire door component failures
Fire Risk Assessments commonly identify issues such as:
- gaps around the door leaf exceeding expected tolerances
- seals that are missing, damaged, painted over or incorrectly fitted
- loose or unsuitable hinges
- self-closing devices that do not fully close and latch the door
- replacement ironmongery that may not be appropriate for a fire-resisting door
- mixed or inconsistent hardware across similar doors
Many of these are relatively straightforward remedial issues once identified, but they can still affect the door’s fire-resisting function.
Fire door gap requirements
Fire door gaps are one of the most frequently checked component issues during an inspection.
Assessors commonly review:
Where gaps are excessive, smoke and fire performance may be reduced.
Intumescent and smoke seals
Seals are another common inspection focus.
Inspectors frequently record problems such as:
- damaged seals
- sections missing
- incorrect seal type
- seals painted over
- loss of continuity around the frame or door edge
For more detail, see our page on intumescent strips regulations.
Hinges and hardware
Hinges and other hardware are expected to be suitable for use on a fire door and securely fixed.
Issues may include:
- missing screws
- signs of wear or distortion
- unsuitable replacement hinges
- incompatible hardware fitted after repair or alteration
You can read more information on our fire door hinges requirements page.
Self-closing devices and other ironmongery
In many buildings, one of the most significant practical checks is whether the fire door closes fully and latches under its own action.
Even where signage, seals and hinges appear correct, a fire door may still be recorded as defective if:
- the closer is missing
- the closer is not operating correctly
- the door binds and fails to close
- the latch does not engage
These issues are commonly identified during both routine checks and formal Fire Risk Assessments.
How component issues are typically addressed
Where fire door component problems are identified, remedial action may involve:
- measuring and correcting gaps
- replacing damaged seals
- upgrading unsuitable hinges or hardware
- adjusting or replacing self-closing devices
- recording the repair and reinspection of the door
The exact action should always reflect the findings of the Fire Risk Assessment and the condition of the individual door.
