What Is a Safety Case Report? (BSA s.85 Guide)

#What Is a Safety Case Report?

A Safety Case Report is a formal document that summarises how you manage building safety risks in your higher-risk building. It is required under section 85 of the Building Safety Act 2022, which was commenced on 16 January 2024. For a high-level overview of what a building safety case is and why you need one, see our companion guide.

The Safety Case Report is a formal document required under section 85 of the Building Safety Act 2022, summarising the assessment of building safety risks and the steps taken to manage them.

— Building Safety Act 2022, s.85

The report serves a specific purpose: it demonstrates to the Building Safety Regulator (BSR) that you understand the safety risks in your building, have taken reasonable steps to manage them, and have plans to reduce the severity of any incidents that do occur.

Every Principal Accountable Person for a higher-risk building in England must prepare a Safety Case Report as soon as reasonably practicable. The report becomes a key part of your Building Assessment Certificate (BAC) application when the BSR calls your building in for assessment.

If you are not sure whether you are the Principal Accountable Person, our PAP Responsibilities guide explains who qualifies and what the role involves. For a comprehensive overview of the full Building Safety Act regime, see our Building Safety Act Complete Guide.

#Safety Case vs Safety Case Report

Before diving into preparation, it helps to understand an important distinction that causes confusion.

The Principal Accountable Person must prepare the Safety Case Report as soon as reasonably practicable. The practical trigger is when the BSR calls your building in for Building Assessment Certificate assessment.

Your safety case is the overall approach to managing building safety risks. It is not a single document -- it is the totality of your risk assessments, management activities, safety measures, maintenance regimes, and evidence that your building is safe. Your safety case is an ongoing, evolving process.

Your Safety Case Report is the formal document that summarises your safety case at a point in time. Think of it as a snapshot: it captures what risks exist, what you have done about them, and what you plan to do next.

The report documents the case. You maintain the safety case continuously; you write the report to demonstrate it.

This distinction matters because the BSR is assessing whether your ongoing safety management is adequate, not just whether your paperwork is in order. A well-written report that describes a poor safety case will not pass assessment. A thorough safety case documented in a clear report will.

#What the Building Safety Regulator Expects

Understanding how the BSR assesses your Safety Case Report helps you prepare one that meets their expectations. The BSR has stated that their assessment is proportionate -- there is no one-size-fits-all standard. What they look for depends on your building's type, age, height, construction, and the specific risks it presents.

The BSR assesses five key areas in your Safety Case Report: expected safety measures for your building type, their effectiveness and maintenance, action on legacy issues, aspects not built to current standards, and evaluation of additional measures.

— BSR Safety Case Toolkit

The BSR considers five key areas during assessment:

#1. Expected Safety Measures

The BSR will check whether your building has the safety measures that would be expected for its type. A 1970s concrete tower block has different expectations from a 2020 timber-framed building. The assessor considers what is reasonable for the building as it exists today.

What to document: List all safety measures currently in place -- fire doors, compartmentation, smoke ventilation, structural fire protection, alarm systems, sprinklers, dry risers, and any other relevant systems. Describe each system's purpose and coverage.

#2. Effectiveness and Maintenance

Having safety measures is not enough -- the BSR wants to know they work and are maintained. A fire door that does not close properly or a ventilation system that has not been tested in years will raise concerns.

What to document: For each safety measure, describe the maintenance regime, testing schedule, most recent inspection results, and any remedial work undertaken. Reference your Golden Thread records where applicable.

#3. Action on Legacy Building Safety Issues

Many higher-risk buildings have known issues from their original construction or from previous management. The BSR wants to see that you are aware of these issues and have taken steps to address them.

What to document: Identify known defects, describe remediation programmes (completed or in progress), and explain how you manage any residual risk from issues that cannot be fully resolved. This includes cladding remediation, compartmentation breaches, and any defects identified during fire risk assessments.

#4. Aspects Not Built to Current Standards

Older buildings were built to the standards of their time. The BSR does not expect every building to meet current Building Regulations, but they do expect you to have considered where your building falls short and what that means for safety.

What to document: Identify where the building does not meet current standards, assess the risk this creates, and describe any measures taken to compensate. For example, a building without sprinklers that would be required in a new build should document the additional fire safety measures in place.

#5. Evaluation of Additional Measures

Finally, the BSR wants to see that you have considered whether more could be done. This is not about spending unlimited money -- it is about demonstrating a thoughtful evaluation of residual risk and whether additional measures would be proportionate.

What to document: Describe any additional measures you have considered, the reasoning for implementing or not implementing them, and any cost-benefit analysis undertaken. The BSR expects proportionate decision-making, not perfection.

#Step-by-Step Preparation Guide

Preparing a Safety Case Report is a structured process. Work through these steps methodically, and you will build a comprehensive report that addresses the BSR's assessment criteria.

#Step 1: Gather Your Building Safety Information

Your Safety Case Report draws on information you should already be maintaining as part of your Golden Thread obligations. Before you start writing, assemble:

• Fire Risk Assessment -- your most recent fire risk assessment and any previous assessments showing trends
• Structural survey reports -- condition assessments, structural engineer reports
• As-built drawings and plans -- original construction documents and any modifications
• Maintenance records -- service logs for fire safety systems, lifts, structural elements
• Compliance certificates -- gas safety, electrical installation, fire alarm commissioning
• Resident engagement records -- complaints, engagement strategy, PEEPs documentation
• Incident reports -- any safety incidents, near misses, and your response
• Previous remediation records -- cladding works, fire door replacements, compartmentation repairs

#Step 2: Identify All Building Safety Risks

Conduct a systematic risk assessment covering all building safety risks. This goes beyond fire risk -- the Building Safety Act covers structural safety, fire safety, and any risk arising from the spread of fire or structural failure.

For each risk, document:

• The risk itself -- what could go wrong, and what would the consequences be
• Likelihood -- how probable is this risk, given current conditions
• Severity -- what would the impact be on residents and the building
• Existing controls -- what measures are already in place to manage this risk
• Residual risk -- what risk remains after existing controls are considered

Structure your risk assessment by building element (structure, exterior, fire safety systems, means of escape, building services) to ensure comprehensive coverage.

#Step 3: Document Risk Mitigation Measures

For each identified risk, describe the steps you have taken to prevent it materialising and to reduce its severity if it does. This is the core of your Safety Case Report and directly addresses section 85(2)(b) and (c) of the Act.

Be specific. Rather than "fire doors are maintained," write "all 147 fire doors are inspected quarterly by [contractor name] under contract [reference]. Last full inspection: [date]. Defects remediated within [timeframe]."

#Step 4: Address Legacy Issues

If your building has known legacy issues -- whether from original construction, cladding concerns, or previous management failings -- document them honestly. The BSR will view a frank acknowledgement of issues with a credible remediation plan far more favourably than an attempt to minimise or overlook them.

For each legacy issue, describe:

• When and how it was identified
• The risk it creates
• What remediation has been completed or is planned
• How you manage the risk in the interim
• The timeline for resolution

#Step 5: Compile the Report

Using the template outline below, assemble your findings into a structured document. The report should be clear enough that someone unfamiliar with your building could understand the safety risks and how you manage them.

#Step 6: Review and Maintain

Your Safety Case Report is a living document. Establish a review cycle and update it when:

• Significant changes are made to the building (major works, system upgrades)
• New risk information emerges (new fire risk assessment findings, incident reports)
• Maintenance regimes change
• After any safety incident
• At regular intervals appropriate for your building (annually at minimum)

#BSR Assessment and Enforcement

Understanding the assessment process helps you prepare with confidence rather than anxiety. The BSR has been clear that their approach is proportionate and building-specific.

#How Assessment Works

When the BSR calls your building in for assessment, you have 28 days to submit your Building Assessment Certificate (BAC) application. Your Safety Case Report is a core part of this application, alongside other required documentation.

The BSR assessor reviews your submission against the five assessment criteria described above. They are looking for evidence that you understand your building's risks, have taken reasonable steps to manage them, and have a credible plan for ongoing safety management.

#What "Reasonable Steps" Means

The Act requires the PAP to take "all reasonable steps" to manage building safety risks. This does not mean eliminating all risk -- that is impossible. It means taking proportionate action based on the severity and likelihood of each risk.

The BSR Safety Case Toolkit provides examples of reasonable steps for common risk categories. These examples are helpful guidance, not a prescriptive checklist. What is reasonable depends on your building's specific circumstances.

#If the BSR Identifies Concerns

If the BSR is not satisfied with your Safety Case Report, the process is typically iterative rather than immediately punitive:

1. Information requests -- the BSR may ask for additional information or clarification
2. Compliance notices -- if specific improvements are needed, the BSR can issue a compliance notice setting out what must be done
3. Enforcement action -- for serious non-compliance that creates a risk of death or serious injury, the BSR can take enforcement action under section 101 of the Act

The overwhelming majority of buildings will go through the standard assessment process. The BSR has stated that they want to work with building managers to improve safety, not to prosecute.

#Hypothetical Scenarios

The following scenarios illustrate how different buildings might approach their Safety Case Report. These are fictional examples for educational purposes.

#Scenario 1: Post-War Concrete Tower Block

Highfield House is a 22-storey concrete-frame tower block built in 1968, comprising 132 flats. The building has a dry riser, emergency lighting, and a stay-put evacuation strategy. No sprinkler system is installed.

The building manager, working with a fire safety consultant, identifies the following key risks:

• Compartmentation concerns -- original fire stopping has degraded in several service risers. A specialist contractor is engaged to survey all risers, and a phased remediation programme is planned over 18 months.
• No sprinklers -- the building was not required to have sprinklers when constructed. The manager documents a cost-benefit analysis: full retrofit would cost approximately GBP 1.2 million. Given the building's concrete construction (inherently fire-resistant) and recent compartmentation improvements, the manager concludes that the existing measures, once the remediation programme is complete, provide proportionate protection. This reasoning is documented in the report.
• Flat entrance doors -- a survey reveals that 23 of 132 flat entrance doors do not provide 30 minutes of fire resistance. A door replacement programme is initiated, funded through the service charge, with completion targeted within 12 months.

The Safety Case Report presents these issues honestly, describes the remediation timeline, and explains interim measures (enhanced fire safety patrols, temporary fire stopping in the worst-affected risers). The BSR assessor appreciates the transparent approach and clear remediation plan.

#Scenario 2: Modern Mixed-Use Development

Riverside Quarter is an 8-storey mixed-use building completed in 2019, with 64 residential units above ground-floor commercial space. The building has a full sprinkler system, fire alarm, mechanical smoke ventilation, and was built to current Building Regulations.

The building manager's Safety Case Report is relatively straightforward because the building was constructed to modern standards. Key elements include:

• Comprehensive maintenance records -- all fire safety systems have been maintained since handover, with digital records in a compliance platform. The report references system-by-system maintenance schedules and test results.
• Cladding review -- although the building has no ACM cladding, the manager has commissioned an EWS1 survey confirming the external wall system meets current standards. The survey report is appended.
• Resident engagement -- the building has an active residents' association. PEEPs assessments have been offered to all residents, with 7 completed plans in place.

The report is concise because the building's risks are well-managed and well-documented. The manager focuses on demonstrating the ongoing management regime rather than identifying and remediating defects.

#Scenario 3: Converted Industrial Building

Millgate Lofts is a converted Victorian mill, 8 storeys, containing 48 residential units. The building was converted to residential use in 2004 and has a mix of original industrial elements and modern residential systems.

This building presents unique challenges because of its mixed construction:

• Original timber floors -- the mill retains original timber floors on levels 3-6, which do not provide the fire resistance expected in a modern residential building. The manager documents enhanced compartmentation measures (fire barriers between units, intumescent coatings on exposed timber) and more frequent fire safety inspections.
• Complex means of escape -- the building's industrial layout means escape routes are not straightforward. The manager has commissioned a fire engineer to review means of escape and has implemented improved wayfinding signage and emergency lighting.
• Heritage constraints -- some fire safety improvements are complicated by the building's listed status. The report documents discussions with the local authority conservation officer and the compromises reached.

The Safety Case Report acknowledges the building's inherent complexities, explains the proportionate measures taken, and provides evidence of ongoing monitoring and review.

#Frequently Asked Questions

The questions below address the most common concerns building managers have about Safety Case Reports. For a fuller explanation of each answer, see the detailed sections above.

What is a Safety Case Report?

A Safety Case Report is the formal document required under section 85 of the Building Safety Act 2022. It summarises your assessment of building safety risks, the steps taken to prevent those risks materialising, and the steps to reduce their severity if they do. It is reviewed by the BSR as part of your Building Assessment Certificate application.

Who must prepare the Safety Case Report?

The Principal Accountable Person (PAP) is legally responsible. Under BSA 2022 s.73(1)(a), the PAP is the Accountable Person who holds the legal estate in possession in the structure and exterior (or is under a relevant repairing obligation for them). In the default case the freeholder remains the PAP. Where an RTM company has taken over management under CLRA 2002 s.96, the PAP designation depends on whether all repairing obligations for the structure and exterior transferred -- the narrow s.72(2)(b) case. You can commission professionals to help, but the legal responsibility remains with the PAP.

Is there a deadline for the Safety Case Report?

There is no single deadline. The Act requires preparation "as soon as reasonably practicable." The practical trigger is when the BSR calls your building in for BAC assessment -- you then have 28 days to submit your application, which includes the Safety Case Report. To track the safety case report deadline alongside other regulatory dates (PEEPs, MOR submissions, S.20 consultations), use the Brocade compliance calendar. For the full deadline picture, see the BSA compliance calendar.

What is the difference between a safety case and a safety case report?

Your safety case is the ongoing process of managing building safety risks -- the totality of your assessment, management, and evidence. Your Safety Case Report is the document that summarises the safety case at a point in time. The report documents the case.

What does the BSR look for during assessment?

The BSR considers five areas: expected safety measures for your building type, their effectiveness and maintenance, action on legacy issues, consideration of aspects not built to current standards, and evaluation of additional measures. See the detailed section above.

Do I need a specific template?

The BSR has not mandated a specific format. The template outline in this guide provides a suggested structure aligned with BSR assessment criteria and the Safety Case Toolkit. Adapt it to your building's circumstances.

How often should I update the report?

Treat it as a living document. Update when significant changes occur (major works, new risk information, incidents) and at regular intervals appropriate for your building. Annually at minimum is a reasonable baseline.

#Fire Safety Measures and Your Safety Case

Your safety case must demonstrate that fire safety systems are not only present but actively maintained and evidenced. Fire doors are a critical component of your compartmentation strategy, and the BSR expects to see a documented inspection programme showing quarterly checks on flat entrance doors and annual checks on common area doors. For detailed guidance on what to document and how to build an evidence trail for fire door inspections, see our fire door inspection requirements guide.

A Safety Case Report is a living document. It must be reviewed and updated whenever there are significant changes to the building, new risk information, safety incidents, or changes to maintenance regimes.

#Next Steps

1. Gather your documentation -- start with your Golden Thread records and most recent fire risk assessment
2. Use the template -- adapt the template outline to your building's circumstances
3. Assess your risks systematically -- work through each building element and safety system
4. Document honestly -- the BSR values transparency and credible remediation plans over perfection
5. Establish your review cycle -- your safety case is ongoing; the report is a snapshot that needs regular updating
6. Consider professional support -- a fire safety consultant can help identify risks and validate your assessment

#A note from the founder

This guide pulls together what I have learned about Safety Case Reports since starting Brocade in January, because the section 85 report is what the BSR reads end-to-end when they come to call your BAC. Brocade's combined Golden Thread record, FRA action tracker, and audit-event chains let you draft against verified evidence rather than half-remembered emails, which is the difference between submitting in 8 weeks versus 8 months. Where my view is still moving is on how much detail the BSR will accept on legacy issues that have a credible remediation plan but no current completion date, since the published assessment criteria leave room either way. If your Golden Thread is incomplete, the Golden Thread guide is the prerequisite read.
