Fire Doors

In short, fire doors save lives and property. They are part of a building’s passive fire protection system and are fundamental to most fire strategies for buildings.

What do fire doors do?

They provide critical protection within a building such as escape routes (stairs and corridors) and places of relative safety, and in separating different fire hazards in a building.

Specific guidance for fire doors relating to all buildings which contain two or more domestic premises and that contain common parts through which residents would need to evacuate in a fire is available on the website:

Fire Safety (England) Regulations 2022: fire door guidance  

Important information about fire doors

  • Fire doors must work correctly
  • They must be tested and third-party certificated to BS 476 – – Part 22 or BS EN 1634 Part 1
  • They must be fitted with the correct and compatible components suited to the door leaf and its purpose
  • Like any fire safety device, they should be installed and maintained by competent people
  • A fire door’s performance should never be compromised
  • Correct glazing and ironmongery must be used
  • No altering or adapting the door leaf on site
  • Always use the correct frames
  • Always use intumescent seals
  • Ensure good installation and maintenance
  • Never prop open a fire door

DOs and DON’Ts for staying safe


  • Specify and use third-party certificated fire doors and components
  • Buy fire doors, frames and components from certificated companies
  • Check the certificate matches the door
  • Make sure you have the correct certification for the door’s intended use
  • Install and maintain fire doors using competent personnel
  • Make sure that ironmongery components are CE marked.


  • Fit a fire door as you would any other door – it’s an engineered safety device
  • Cut vision panels and other holes on site
  • Patch up a fire door
  • Take risks by reducing the specification
  • Disconnect a fire door closer
  • Prop or wedge open a fire door

Did you know?

  • Leaving fire doors wedged or propped open disregards the safety of others.  Fire doors serve a vitally important purpose preventing the spread of fire to escape routes which allow people the time to evacuate the building safely.
  • All fire doors should be fitted with intumescent seals – they expand between five and ten times their original size, sealing the gaps around the perimeter of the door and holding the door construction firmly in place.
  • Some fire doors may also need smoke seals and/or acoustic seals.
  • Essential ironmongery for fire doors must be CE marked even though fire doors themselves don’t need to be (at present).
