The withdrawal of BS 476-22 in September 2029 will change how fire doors are tested, classified and specified in the UK, with all new products required to meet EN 13501-2 classifications based on EN 1634-1 testing.
For contractors, facilities managers and architectural ironmongers, the transition marks the end of the dual testing system. While existing fire doors certified to BS 476 will remain compliant for their service life, new installations after the deadline must meet the updated European classification framework.
Fire doors are a key part of passive fire protection, designed to contain fire and smoke, protect escape routes and support emergency response. Under the revised system, performance will be defined using classifications for integrity (E), insulation (I) and smoke control (S), rather than the familiar FD30, FD60 or FD120 ratings.
The change introduces practical implications across the supply chain. Manufacturers will need to retest products, and some configurations or components may not transition directly. This could affect product availability and limit flexibility around door sizes, glazing and hardware selection.
Organisations responsible for fire door management are being advised to plan ahead. This includes maintaining accurate records, ensuring inspections are carried out by competent professionals and reviewing replacement programmes scheduled beyond the withdrawal date.
Early engagement with manufacturers and suppliers is expected to be important in managing the transition and avoiding disruption as the deadline approaches.
The move aligns UK fire testing with European standards, placing greater emphasis on traceability, verified performance data and consistency in fire resistance classification.
