The building safety case report

In short: A safety case report is the document in which the principal accountable person demonstrates that they have assessed the building safety risks - the spread of fire and structural failure - and are taking all reasonable steps to manage them. It is required under the Higher-Risk Buildings (Management of Safety Risks etc) (England) Regulations 2023, and the PAP must notify the Building Safety Regulator once it is prepared.

The safety case vs the safety case report

These two terms are often confused. The safety case is the full body of evidence and analysis that shows a building is safe - the risk assessment, supporting documentation, inspection records, remediation evidence and the ongoing management arrangements. It is a living body of information. The safety case report is the structured summary derived from it, and it is what the PAP submits to the Regulator. Think of the safety case as the evidence base and the report as the argument built on it: a clear account of how the building is being kept safe. The BSR can ask for the full safety case at any time and will assess the report against it.

What it must contain

A safety case report draws together, in one place:

• A building profile - a description of the building, its design, construction, height, occupancy and any significant changes over its life, setting the context for the risk assessment.
• The building safety risk assessment - the identified risks of fire spread and structural failure, based on evidence and the building's actual condition rather than assumptions.
• The management measures in place to prevent those risks from materialising and reduce their severity if they do - the physical systems (detection, suppression, compartmentation), the inspection and maintenance regime, and the management processes that monitor risk over time.
• Evidence of competence - that the people responsible for building safety, including any contractors doing safety-critical work, are competent to do it.
• Resident engagement - how residents are engaged on safety, can raise concerns, and how those concerns are handled.
• Change management - how changes to the building (works, repairs, change of use) are assessed for their safety impact before they happen.
• The evidence that supports all of the above, drawn from the golden thread.

Who prepares it, and the standard applied

The principal accountable person is legally responsible for the report, though most engage specialist consultants to prepare it given the technical complexity - the PAP remains accountable for its accuracy either way. The BSR expects reports to be evidence-based, proportionate and genuinely reflective of how the building is managed. Generic, template-based reports not backed by actual inspection evidence are unlikely to satisfy scrutiny, and a report that overstates the measures in place - claiming a structured inspection programme that doesn't really exist - creates serious legal and regulatory risk.

Common weaknesses the BSR scrutinises

In practice, safety case reports fall short most often where: risk assessments rest on assumptions rather than survey and inspection evidence; an inspection programme exists on paper but the records of actual inspections are missing; the facade and external wall assessment (a top-priority risk area) hasn't been completed; or the golden thread isn't in place, so the report can't be properly evidenced.

The building assessment certificate

The Building Safety Regulator will, in time, direct each principal accountable person to apply for a building assessment certificate. The safety case report is assessed as part of that process. Once issued, the certificate must be displayed in the building. It is an offence to fail to apply when directed, or to occupy without meeting the requirements.

A living document

A safety case report is not a one-off. As the building, its occupants and its risks change, the assessment and the report must be kept current - which is why the underlying golden thread has to be accurate and maintained.

How CTS helps

CTS builds your safety case from a structured assessment of the building, draws the evidence from your golden thread, and keeps it current on the CTS BuildSafe platform - so you are ready when the Regulator calls for your building assessment certificate.

The safety management system

One required section of the report is a summary of your safety management system - the organised way you manage building safety risks day to day. It is worth understanding on its own terms.
