When Must You Replace a Fire Door Instead of Repairing It? (UK)

This page is for building managers deciding whether remedial work is sufficient or full replacement is required.

The central issue

Can the door still achieve its intended fire-resisting performance?

If yes, repair may be appropriate.
If not, replacement may be necessary.

Situations that often lead to replacement

Examples can include:

  • severe structural damage
  • incorrect or unknown door type
  • extensive unauthorised alteration
  • failure of critical components

Situations often suitable for repair

Defects commonly identified include:

  • closer adjustment
  • seal replacement
  • hardware upgrade
  • signage installation

How inspection results determine repair or replacement

Most decisions about repairing or replacing a fire door arise during routine inspections. During a formal inspection, defects such as excessive door gaps, damaged seals, or missing signage are identified and recorded.

Our guide to fire door inspection requirements explains how inspections are carried out and what defects inspectors typically record.

Who makes the call?

Usually a competent assessor or contractor, often guided by the Fire Risk Assessment.

Why uncertainty appears in reports

Because inspectors may identify symptoms but not specify engineering solutions.

What organisations usually do

Seek specialist advice and document decisions and evidence completion of work.
