Shocking FDIS data reveals three-quarters of UK fire doors don't meet safety standards. One in three was never fit for purpose. Here's what every building owner must check.. A National Scandal Hidden in Plain Sight Fire doors are the last line of defence between a fire and the people behind them. Yet data from the Fire Door Inspection Scheme (FDIS), based on over 100,000 inspections in 2021, reveals a catastrophic failure rate: 75% of fire doors in the UK do not meet required standards . Even more alarming: 31% were never fit for purpose — meaning they failed from the moment they were installed. Why Are So Many Failing? The three most common failure reasons: 1. Excessive gaps — gaps around door edges exceeding 3mm allow fire and smoke to pass through 2. Smoke seal deficiencies — missing, damaged, or incorrectly fitted intumescent strips and smoke seals 3. Maintenance failures — doors not closing properly due to damaged closers, hinges, or frames The Legal Position Under the Fire Safety (England) Regulations 2022, building owners of high rise residential buildings (18m+) must: Check all fire doors in common areas at least every quarter Check all flat entrance doors at least annually Keep records of all inspections Repair or replace defective doors without delay Failure to comply is a criminal offence with potentially unlimited fines.
