For higher-risk buildings in England, the Accountable Person must assess and manage building safety risks and produce a safety case report that demonstrates how those risks are controlled. SI 2023/907 sets out ten prescribed risk management principles. This guide explains what duty-holders need in practice — and how a structured digital record supports BSR readiness.
“A safety case is not a one-off PDF. It is a living demonstration that fire and structural risks are understood, controlled, and evidenced throughout occupation.”
Where the safety case duty comes from
SI 2023/907 requires Accountable Persons to follow ten risk management principles when assessing and managing building safety risks — principally the spread of fire and structural failure. The safety case report is the coherent narrative and evidence pack that shows those principles are applied to the specific building.
The report sits alongside Key Building Information (SI 2023/396), mandatory occurrence reporting, resident engagement, and the occupied-phase golden thread. Together they form the occupied compliance picture the Building Safety Regulator expects to see.
The 10 risk management principles
Each principle under SI 2023/907 reg.4(1)(a)–(j) should be individually considered and attested — not buried in a generic policy statement. Typical themes include understanding the building, identifying risks, implementing control measures, monitoring performance, and learning from incidents.
- Clear description of the building and its safety-critical systems
- Identified fire and structural risks with proportionate controls
- Roles and competence of duty-holders and contractors
- Resident engagement and information arrangements
- Monitoring, review, and continuous improvement processes
Link engagement to the safety case
Resident engagement is not a separate brochure exercise. Consultation outcomes, engagement strategy reviews, and how resident concerns feed into risk management should be visible in the safety case evidence trail. Publishing or approving a safety case without engagement linkage weakens the duty-holder’s position.
A practical structure that works
Organise the safety case into clear sections with named owners, version history, and supporting documents in the golden thread. Material changes to the building or its management should trigger a controlled revision — with registration notifications where SI 2023/315 applies.
Platforms such as Threadsovereign support structured safety case sections, principle-by-principle attestation, engagement linkage, and BSR submit readiness in the occupied portal — on every paid plan.
Conclusion
Accountable Persons who treat the safety case as a living management system — not a submission event — are better prepared for BSR scrutiny and for day-to-day decisions that protect residents. For product walkthroughs, see threadsovereign.co.uk/hrb-compliance-software and threadsovereign.co.uk/faq.
