Safety Case Reports for Accountable Persons: SI 2023/907 Principles Explained

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 (reg.4(1)(a)–(j))

SI 2023/907 reg.4(1) lists ten prescribed principles. Each should be individually considered and attested for the building — not buried in a generic policy statement. Threadsovereign’s full reference guide lists each principle with plain-English summaries at threadsovereign.co.uk/safety-case-report.

• (a) Identify hazards — fire-spread and structural-failure hazards affecting people in or about the building
• (b) Evaluate risks — likelihood and severity arising from those hazards
• (c) Implement measures — all reasonable steps to prevent risks materialising and reduce severity if they do
• (d) Monitor effectiveness — check that control measures actually work
• (e) Record assessments — written record of the assessment and steps taken
• (f) Review periodically — and whenever there is reason to suspect the assessment is no longer valid
• (g) Consult residents — and residential-unit owners about decisions that affect risk management
• (h) Consider vulnerable persons — including those who need assistance to evacuate
• (i) Coordinate with other Accountable Persons — where more than one AP is responsible for parts of the building
• (j) Emergency procedures in place — so people can be kept safe if a risk materialises

Full safety case resource

For the complete educational resource — instruments, principle-by-principle table, BAC cross-links, common failures, and primary sources — see threadsovereign.co.uk/safety-case-report. Pair it with Key Building Information (threadsovereign.co.uk/key-building-information) and mandatory occurrence reporting (threadsovereign.co.uk/mandatory-occurrence-reporting).

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.
