What a safety case report is, and is not
The Building Safety Act 2022 asks the Principal Accountable Person (PAP) for every occupied higher-risk building in England to do two related things. Section 83 and 84 require each Accountable Person to assess the building safety risks (the spread of fire and structural failure) and take all reasonable steps to prevent them materialising and to limit the consequences if they do. Section 85 then requires the PAP to prepare a safety case report: a document that summarises those risks, the steps taken, and the management system that keeps the steps working.
The report is not the safety case. The safety case is all of it: the fire risk assessment, the external wall appraisal, the structural appraisal, drawings, the fire strategy, test and maintenance records, the evacuation strategy, the resident engagement strategy, and the arrangements that hold it together. The report distils that into a readable document that points at the evidence rather than reproducing it. BSR's guidance is explicit that a report padded with generic text or copied wholesale from another building is not what it wants.
Who writes it and when BSR wants it
The duty sits with the PAP. Where a building has more than one Accountable Person (a freeholder and a housing association, say, or a management company and a commercial landlord), each must assess and manage the risks for their part and cooperate with the PAP, who pulls it together. Consultants, managing agents and building safety managers frequently do the drafting, but the PAP must own and understand the content, because it is the PAP who will be asked about it.
Since the Building Safety Regulator became a standalone body under the Ministry of Housing, Communities and Local Government in January 2026, it has changed how it calls buildings in. From July 2026 the building assessment certificate process has been risk-based and intelligence-led: BSR directs the PAP to apply based on what it knows about the building, rather than working through a fixed timetable. The practical effect is that you do not know when the direction will arrive, and once it does the report and the evidence behind it need to be ready. A report written in the 28 days after a direction is a report written under pressure.
The eleven sections
The regulations describe the content; BSR's building assessment criteria describe what its assessors look for. Put together they give a natural structure of eleven sections. The free building safety case report template uses exactly these headings, with a note under each on what to write.
1. The building and its environment
The regulator needs to understand what the building is before it can judge whether the risks are understood. Registration number, address and UPRN, height and storeys, number of residential units, construction type and date, the external wall system, the uses within the building (including any commercial or care use), what surrounds it, how fire appliances reach it, and the history of refurbishment and remediation. If there has been cladding work, say so here.
2. People responsible for the building
Name the PAP, the building owner if different, every other Accountable Person and the part of the building each is responsible for, the Responsible Person under the Regulatory Reform (Fire Safety) Order 2005, the managing agent and any building safety manager or director. Then explain how these people share information with each other. BSR has flagged unclear dutyholder boundaries as a recurring weakness.
3. Building safety risk assessment
Summarise the assessment of the two building safety risks: the scenarios identified for the spread of fire and for structural failure, how likely each is and what the consequences would be. Describe the methods (fire risk assessment of the common parts, fire risk appraisal of external walls under PAS 9980, structural appraisal, HAZID or bow tie workshops) and who did them, with their competence. Then give the significant findings and recommendations. This is the heart of the report.
4. How risks are prevented and controlled
For each significant risk, the reasonable steps taken: compartmentation, fire doors, detection and alarm, smoke control, suppression, means of escape, structural protection and external wall measures. Show why they are proportionate for this building, and how together they demonstrate compliance with section 84. Where a recommended action has not yet been completed, say when it will be and what interim measures are in place.
5. Safety management system
Controls only work if they are maintained. Describe the policies, roles and competence, the planned maintenance, inspection and testing regime for each safety measure (who does it and how often), how records are kept, how performance is monitored and reviewed, and how actions are tracked to completion. This section is where the golden thread is referenced.
6. Managing works and change
How works to the building are controlled so they do not introduce new risks: assuring the competence of designers and contractors, the quality of materials, permits to work, managing building safety risk during the works, and change control for anything that alters the safety case (which then triggers a revision of this report).
7. Emergency planning and evacuation
The evacuation strategy (stay put, simultaneous, phased) and the reasoning behind it, arrangements for residents who need assistance to evacuate, the contents of the secure information box, liaison with the fire and rescue service, how residents are told what to do, and how the building would be recovered after an incident.
8. Resident engagement
Section 91 of the Act requires a resident engagement strategy. Summarise it: how residents are informed about building safety, consulted on decisions that affect it, able to request information and raise concerns, and how their feedback has changed what you do. Link to the building safety complaints procedure.
9. Mandatory occurrence reporting
Section 87 requires a mandatory occurrence reporting system. Describe who can report, how reports are received and assessed, how safety occurrences are notified to BSR within the required timescales, and how lessons feed back into the safety case. Include the occurrence log as an appendix.
10. Known issues, remediation and residual risk
Be candid. Known defects (cladding, compartmentation breaches, structural concerns), remediation completed or in progress with dates, interim measures such as enhanced detection or waking watch, and how residual risk is being managed and by whom it has been accepted. Assessors read this section closely; omissions here undermine everything else.
11. Review, assurance and continuous improvement
What triggers a review of the report, how revisions are recorded and BSR notified, any independent assurance or audit, and the improvements planned. Close with the revision history as an appendix.
The evidence behind the report
Every statement in the report should be traceable to something you hold. The Higher-Risk Buildings (Keeping and Provision of Information etc.) (England) Regulations 2024 list the categories of information that make up the golden thread, and BSR expects to be able to ask for any of it. In practice the evidence behind a safety case report includes:
- BSR registration confirmation and the key building information submission.
- The fire risk assessment of the common parts and the fire risk appraisal of external walls.
- Structural appraisal and compartmentation survey where carried out.
- Fire door inspection records: quarterly for communal doors, annual for flat entrance doors.
- Service and test records for the fire alarm, emergency lighting, smoke control, sprinklers, dry risers and firefighting lifts.
- The evacuation strategy, person-centred fire risk assessments and the secure information box contents.
- The resident engagement strategy, complaints procedure and the complaints log.
- The mandatory occurrence reporting procedure and the occurrence log.
- The remediation programme, interim measures and their review dates.
- The dutyholder schedule and any cooperation agreements between Accountable Persons.
The report should say where each of these is held, its version and date, and who is responsible for keeping it current. That is what the golden thread index appendix is for.
Six reasons reports get sent back
- Generic text. Paragraphs that could describe any block of flats. Assessors want to see this building, this wall system, this evacuation strategy and why.
- No risk assessment summary. A report that lists controls without first explaining the scenarios, likelihoods and consequences cannot show the controls are proportionate.
- Unclear dutyholders. It is not obvious who the PAP is, which Accountable Person covers which part, or how they talk to each other.
- Silence on known defects. Remediation that everyone knows about but the report does not mention.
- Evidence that cannot be produced. The report refers to a fire strategy or a structural appraisal nobody can find when BSR asks for it.
- No revision history. The report has clearly been edited but there is no record of what changed, why, or whether BSR was told.
Keeping it a living document
Section 85 requires the report to be revised when appropriate, and the regulations require BSR to be told as soon as possible when a revised report is prepared. The triggers are changes to the building or its use, changes to the risks or controls, works, safety occurrences, new information (a new survey, a product recall, a change in guidance) and the periodic review most PAPs set annually. Each revision needs an issue number, a date, a summary of what changed and why, and a note of whether BSR was notified.
This is where a Word document starts to struggle. The report is only one artefact; the fire door checks, test records, actions, occurrences and documents it points at all change independently. If they live in separate folders and spreadsheets, keeping the report truthful means someone reconciling them by hand every time.
Frequently asked
What is the difference between a safety case and a safety case report?
The safety case is everything: all the information, assessments, drawings, test records and management arrangements that show the building safety risks are understood and controlled. The safety case report is the summary document that distils it for the Building Safety Regulator, pointing at the evidence rather than reproducing it.
How long should a safety case report be?
There is no set length. BSR's guidance favours a concise report that is specific to the building and signposts the evidence. Many reports for a single block run to 30 to 60 pages plus appendices. Generic padding copied between buildings is the most common criticism.
How often must a safety case report be reviewed?
Whenever there is a material change: to the building, its risks, its controls, after works, after a safety occurrence, or when new information comes to light. Most Principal Accountable Persons also set a fixed review interval, typically annual. You must tell BSR as soon as possible when the report is revised.
Can a consultant write the safety case report for us?
Yes, and many do, but the legal duty stays with the Principal Accountable Person, who must understand and own the content. A good consultant will usually start with a readiness or gap audit, then help assemble the evidence and draft the report with the PAP.
