Building a safety case the regulator will accept

A safety case report is an argument. It says, in effect, here are the major safety risks in this building, here is what we have done about them, and here is the evidence that what we have done is real and maintained. The Building Safety Regulator can ask the Accountable Person of an occupied higher-risk building to produce one, and the report it receives is judged less on its length than on whether the argument holds together. The reports that struggle are not the short ones. They are the ones that assert safety without being able to reach the evidence underneath.

What a safety case is for

Under the Building Safety Act 2022, the Accountable Person must assess the building safety risks, meaning the spread of fire and structural failure, take all reasonable steps to manage them, and keep a safety case from which a safety case report can be produced. The report is the readable account of that work. It is not a single inspection or a one-off survey; it is the standing case that the building is being managed safely, refreshed as the building changes.

The honest test is traceability. For every claim of safety, can a reader follow it down to the document that supports it. A claim that fire doors are inspected should land on a dated inspection record. A claim that the external wall has been reviewed should land on the review itself. Where the chain breaks, the claim is just an assertion, and a regulator reading carefully will find the break.

The parts that hold it together

A safety case report tends to work when it covers a few things well rather than many things thinly.

• A clear description of the building, its construction, its height and storey count, and what makes it a higher-risk building.
• The fire and structural risks identified, and how each was assessed.
• The measures controlling those risks, from the external wall position to compartmentation, alarms, lifts and evacuation strategy.
• The evidence that those measures exist and are maintained, each piece dated and owned.
• The system for residents to raise concerns, and how those concerns feed back into the case.

The connective tissue between all of these is the golden thread, the accurate and current digital record the Act expects the Accountable Person to hold. A safety case is, in practice, the golden thread organised into an argument. We treat the underlying habit in the golden thread is a habit, not a document.

Where reports fall down

Three failures recur, and all of them are about the gap between claim and proof.

The first is the orphaned assertion: a statement that something is safe with nothing behind it. The second is the stale record: real evidence, but a year past the point where it still describes the building, so the case is true about a building that no longer exists. The third is the unfindable record: the evidence exists, somewhere, but cannot be produced quickly, which to a regulator is close to not existing at all.

Each of these is a record-keeping failure dressed up as a safety failure. The building may well be safe; the case simply cannot show it. That distinction is cold comfort when the Regulator is asking and the answer is in a contractor's email from eighteen months ago.

Keeping the case alive

A safety case is not finished when it is written. The building changes, work is done, doors are replaced, the external wall is remediated, and each change should land in the case. The discipline that keeps a case current is the same one that keeps a fire safety log current: capture at the time, date it, own it, and let it flow into the standing record rather than sitting in a parallel pile.

The fire risk assessment is a major feeder. Required of the responsible person under the Regulatory Reform (Fire Safety) Order 2005 and widened by the Fire Safety Act 2021 to cover the structure, external walls and flat entrance doors, it produces both findings and remedial actions. The findings inform the case; the actions need owners, dates and closure, and an open action that the case does not acknowledge is a weakness a reviewer will spot.

A short readiness check

Before a safety case report goes to the Regulator, it is worth running a plain test over it. A strong case answers yes to each of these without hesitation.

• Can every safety claim be followed to a dated record.
• Is the evidence current to the building as it stands today.
• Can the records be produced quickly, from one place.
• Are the open remedial actions acknowledged, with owners and dates.
• Does resident feedback feed back into the case.

If any of these is a maybe, that is where the report is exposed, and it is cheaper to find it yourself than to have it found for you.

The practical close

The buildings whose safety cases stand up are rarely the ones with the most expensive consultants. They are the ones whose records were kept in order all along, so the case was an act of assembly rather than archaeology. The work that makes a safety case acceptable is mostly done in the months before anyone asks for it.

SAMRISK keeps the assessments, plans, certificates and remedial actions against one building record, so the safety case is drawn from evidence that is already dated, owned and findable rather than gathered in a rush. You can see how it fits together on the safety case and audits pages. This is general guidance rather than legal advice, and a specific report should be prepared with your own competent advisers and checked against the current expectations of the Regulator.
