Question to the Ministry of Housing, Communities and Local Government:

To ask His Majesty's Government what standard building safety assessors use when assessing fire-safety defects other than defects of external wall systems to determine whether a defect is life-critical.

Part 4 of the Building Safety Act 2022 requires that building safety risks in Higher Risk Buildings are assessed, managed and controlled. The assessment must be suitable and sufficient and all reasonable steps must be taken to manage and control the building safety risks.

The Act does not set out specific standards that should be used. However, standards and guidance relevant to other regulatory regimes such as the Regulatory Reform (Fire Safety) Order 2005 and BS 9792:2025 Fire Risk Assessment. Housing. Code of Practice will be relevant. Assessors can also refer to the published criteria used by the Building Safety Regulator for Building Assessment Certificate applications.

The assessment of ‘life critical fire safety defects’ does not form part of the Act. It is instead a feature of the Developers’ Remediation Contract and the Responsible Actors Scheme, which encompass a wider range of buildings.
