What Is PAS 9980?<\/h2>\n
PAS 9980:2022 (Publicly Available Specification)<\/a>, published by the British Standards Institution (BSI), sets out a structured methodology for assessing fire risk in external wall construction of existing multi-occupied residential buildings.<\/p>\n In practice, PAS 9980 is the most common framework used when a competent professional undertakes a FRAEW-style appraisal of an external wall system.<\/p>\n PAS 9980 matters because external walls are now a clearer regulatory focus. The Fire Safety Act 2021 clarified that, for multi-occupied residential buildings, the building\u2019s structure, external walls and flat entrance doors fall within scope of the Fire Safety Order \u2014 and Responsible Persons must ensure these elements are included in fire risk assessments where relevant.<\/p>\n Where an external wall system could materially affect life safety (for example, fire spread over the fa\u00e7ade, impact on escape routes, or evacuation strategy), PAS 9980 provides the recognised \u201chow\u201d for a proportionate, risk-based appraisal.<\/p>\n The Fire Safety Act 2021<\/a> clarified that external walls, cladding systems, balconies and attachments fall within the scope of the Regulatory Reform (Fire Safety) Order 2005<\/a>.<\/p>\n \u201cFRAEW\u201d is commonly used as the label for a Fire Risk Appraisal of External Walls. PAS 9980 is the framework that underpins that appraisal in the UK market.<\/p>\n A PAS 9980-aligned appraisal typically requires the assessor to consider both:<\/p>\n That \u201cprobability + consequence\u201d framing is one reason PAS 9980 is seen as more useful than simple \u201cheight-based\u201d assumptions.<\/p>\n A PAS 9980 appraisal typically pulls together multiple evidence sources to form a defensible risk conclusion, such as:<\/p>\n PAS 9980 is not designed to be a \u201ctick-box\u201d exercise \u2014 it is intended to support competent professional judgement using a structured approach. PAS 9980 does not prescribe fixed thresholds; it requires structured professional judgement informed by building-specific evidence.<\/p>\n Approved Document B<\/a> is Building Regulations guidance (primarily design \/ compliance expectations), while PAS 9980 is an appraisal methodology aimed at existing buildings and life safety risk decision-making.<\/p>\n In external wall appraisal work, professionals often cross-reference Approved Document B as part of understanding intended performance and relevant benchmarks, but PAS 9980 is focused on risk-based appraisal rather than a simple pass\/fail compliance statement.<\/p>\n These get conflated a lot<\/a>.<\/p>\n A PAS 9980 appraisal can sometimes inform the technical understanding that sits behind an EWS1 outcome, but they are not the same document and not commissioned for the same reason.<\/p>\n PAS 9980-aligned appraisal is most commonly commissioned where one or more of the following apply:<\/p>\n PAS 9980 is risk-based \u2014 height can influence consequence, but height alone should not be treated as the only trigger.<\/p>\n While reporting styles vary, a strong PAS 9980-aligned output should typically:<\/p>\n Set out proportionate recommendations (which may range from \u201cno major action\u201d through to \u201cfurther investigation\u201d or \u201cremediation required\u201d)<\/p>\n Provide an auditable, evidence-led basis for life-safety decision-making, particularly where interim measures or remediation strategy are being justified.<\/p>\n If a PAS 9980 appraisal identifies life-safety relevant external wall risk, the Responsible Person should ensure the building\u2019s fire risk assessment reflects that reality \u2014 particularly where it affects:<\/p>\n At Fire Risk Assessment Network, we undertake PAS 9980-aligned external wall appraisals<\/a> and support duty holders in interpreting fa\u00e7ade risk within the wider fire safety and compliance framework.\u00a0If you need help understanding whether PAS 9980 is the right route for your building \u2014 or you need a quotation \u2014 get in touch.<\/p>\nWhy PAS 9980 Matters for Responsible Persons<\/h2>\n
