The Fire Safety Act 2021: external walls and flat entrance doors are now in scope

The Act ended the argument about whether cladding, balconies and front doors are covered by the Fire Safety Order. What it means for your fire risk assessment and the prioritisation guidance that came with it.

The Fire Safety Act 2021 came into force on 16 May 2022. It is short, but it settled an important question: in any building containing two or more sets of domestic premises, the Regulatory Reform (Fire Safety) Order 2005 applies to the structure, the external walls (including cladding, balconies, windows and anything attached to them) and the entrance doors to individual flats that open onto common parts.

What changed in practice

Fire risk assessments for blocks of flats must now consider the external wall system and the flat entrance doors. An assessment that stops at the corridor is no longer suitable and sufficient. In many cases the assessor will need to recommend a specialist external wall appraisal (a PAS 9980 assessment) and a fire door inspection programme rather than attempt to assess them from the ground.

The prioritisation tool

Because thousands of assessments needed updating at once, government issued the Fire Risk Assessment Prioritisation Tool to help responsible persons decide which buildings to reassess first, based on height, cladding type, occupancy and other risk factors. Using it and recording the result is a defensible way to programme the work.

PAS 79-2. The 2020 edition of PAS 79 has a dedicated part for housing, which sets out how to assess the common parts of blocks of flats including the items brought in by the Act. Our housing assessments follow it.

Flat entrance doors

The Fire Safety (England) Regulations 2022 built on the Act by requiring annual checks of flat entrance doors in buildings over 11 metres, using best endeavours to gain access. A door check covers the self-closer, the seals and strips, the gaps, the glazing and any damage. Findings feed into a replacement or repair programme.
