What the safety case is in law
For England higher-risk buildings, Accountable Persons must assess and manage building safety risks — principally the spread of fire and structural failure — and produce a safety case report that demonstrates how those risks are controlled. SI 2023/907 reg.4 sets out ten prescribed risk management principles; reg.5 addresses the safety case report itself.
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 — linked to the golden thread, Key Building Information, occurrences, and resident engagement.
All 10 principles (reg.4(1)(a)–(j))
Each principle should be individually considered and attested for the building — not buried in a generic policy statement. Summaries below are plain English; verify against the statutory text.
| # | Principle | Plain-English meaning |
|---|---|---|
| (a) | Identify hazards | Identify the building safety hazards that could lead to the spread of fire or structural failure affecting people in or about the building. |
| (b) | Evaluate risks | Evaluate the risks arising from those hazards — likelihood and severity for people in or about the building. |
| (c) | Implement measures | Take all reasonable steps to prevent building safety risks materialising and to reduce the severity of any incident that does occur. |
| (d) | Monitor effectiveness | Monitor the effectiveness of the measures taken to manage building safety risks. |
| (e) | Record assessments | Make and keep a written record of the assessment of building safety risks and of the steps taken. |
| (f) | Review periodically | Review the assessment and the steps taken regularly, and when there is reason to suspect they are no longer valid. |
| (g) | Consult residents | Consult residents (and owners of residential units) about decisions that affect the management of building safety risks, in line with the engagement duties. |
| (h) | Consider vulnerable persons | Have regard to the particular needs of residents who are more likely to be affected by a building safety incident — including those with disabilities or who need assistance to evacuate. |
| (i) | Coordinate with other Accountable Persons | Where more than one Accountable Person is responsible for parts of the building, cooperate and coordinate so risks are managed coherently across the whole. |
| (j) | Emergency procedures in place | Have emergency arrangements in place so that, if a building safety risk materialises, people in or about the building can be kept safe. |
Treat it as a living management system
- Named sections with owners and version history
- Evidence linked into the golden thread — not orphan PDFs
- Material changes trigger a controlled revision
- Registration / KBI updates stay coherent with safety-case assertions
Engagement, occurrences, and BAC
Resident consultation outcomes and engagement strategy reviews should be visible in the safety-case evidence trail (principle (g)). Mandatory occurrence reporting arrangements and lessons learned feed principles (d), (f), and (j). GOV.UK BAC guidance expects the safety case report as a core pack document — readiness starts before a direction letter arrives.
