Certain domestic fire doors should be able to resist fire for up to 30 minutes.

The ongoing investigation into the Grenfell Tower tragedy highlighted that composite flat entrance fire doors manufactured by Manse Masterdor do not meet this standard. Manse Masterdor ceased trading in 2014, so this model of door is no longer being manufactured.

The National Fire Chiefs Council has advised that the risk to public safety remains low. But it recommends that owners of buildings with this type of door should review their fire risk assessments and consider replacing the doors.

The government provides advice for building owners on assurance and replacing of flat entrance fire doors.
