Building safety case report: what it is and what goes in it
The building safety case report is the document submitted to the Building Safety Regulator showing how a higher-risk building's safety is managed: the building, its risks, the systems in place to control them, and the evidence behind the assessment. It is built on the golden thread.
What the safety case is
Under the Building Safety Act 2022, the principal accountable person must prepare a building safety case report for each higher-risk building. The safety case is the structured assessment of how the building's safety is managed: what could go wrong (fire and structural risks), what is in place to prevent or control it, and how the building is operated and maintained safely.
The report is the written version of that assessment, submitted to the Building Safety Regulator when required, typically as part of an application for a building assessment certificate. The BSR has said there is no fixed template: the report must reflect the building it describes. What the regulator does expect is that the report is honest, evidence-based and current, and that the evidence lives in the golden thread.

Why the report stands or falls on your records
Every claim in the safety case report needs evidence: the fire risk assessment, inspection and test logs, compliance certificates, asset registers and change records that show the building is being managed safely. Those records are the golden thread.
If the records are scattered, missing or out of date, the report is either thin or wrong, and the regulator's refusal data shows the consequences: in 2026, 66% of building assessment certificate applications have been refused, with the BSR citing process compliance rather than effective management of safety. The condition of your golden thread is the condition of your safety case.
Preparing the evidence base
We do not write the safety case report: that is the principal accountable person's judgement, and it should stay theirs. What we do is make the evidence base ready:
- Gap-check - your records against the prescribed information set
- Structure and index - consistent naming, version history and a document register
- Validate - duplicates removed, dates and statuses reconciled, gaps recorded
- Deliver - an evidence pack your team can cite section by section
Questions, answered
Is there a template for the building safety case report?
The Building Safety Regulator has said there is no single template: the report must reflect the building it describes. GOV.UK's guidance sets out what to include, and the regulator's safety case toolkit gives reasonable steps and practical examples. A structured contents checklist, like the one on this page, is a sound starting point.
Who has to submit a building safety case report?
The principal accountable person must prepare and submit the report to the Building Safety Regulator, typically when applying for a building assessment certificate. The accountable person holds the underlying duty to keep the building safe.
How often does the safety case report need updating?
The safety case must be kept up to date, and the report should be reviewed whenever there is a significant change to the building, its use or its residents. The BSR expects the report it reviews to reflect the building's current state, not a historic one.
What is the difference between a fire risk assessment and the safety case report?
The fire risk assessment is one input, covering fire safety specifically. The safety case report is the wider assessment of how the building's safety is managed, including fire and structural risks, management systems, resident engagement and occurrence reporting, with the fire risk assessment sitting inside it as evidence.
What happens if the regulator refuses the application?
A refused application means the records and assessment have to be fixed and resubmitted under a harder spotlight, with determination times the BSR has admitted are running twice as long as first expected. Getting the evidence base in order before applying is the difference between one submission and two.
