What the Building Safety Regulator looks for in occupation

Construction ends and a different kind of scrutiny begins. The gateways governed the building up to the point people moved in; from then on, the Building Safety Regulator's interest is in how the occupied higher-risk building is run. The Regulator became the Building Control Authority for all higher-risk buildings in England in October 2023, and from January 2026 it is being established as a standalone body rather than sitting within the Health and Safety Executive. Whatever its institutional home, its question in occupation is consistent: is this building being managed safely, and can you show it.

The shift from "is it built right" to "is it run right"

In occupation the burden sits on the Accountable Person, and the Principal Accountable Person where there are several. The Act asks them to register the building, assess the building safety risks of fire spread and structural failure, take all reasonable steps to manage those risks, and hold a safety case from which a report can be produced on request. The Regulator's review is built around whether those things are genuinely happening, not whether they were once set up.

The distinction is worth dwelling on. A building that registered correctly, wrote a strong safety case, and then let its maintenance and records drift is not in good standing. Occupation-phase oversight is continuous in spirit. It assumes the building keeps changing and asks whether the management keeps pace.

The safety case report, on request

The most visible thing the Regulator can ask for is the safety case report. It wants to see the major risks identified, the measures controlling them, and the evidence that those measures are real and maintained. What it is testing, underneath, is traceability: can each claim of safety be followed to a dated record. A report that reads well but cannot reach its evidence is the one that draws follow-up questions.

The reports that hold up are drawn from records that were already in order. The ones that struggle were assembled in a hurry and describe an idealised building. We go into what makes a report acceptable in building a safety case the regulator will accept.

The standing duties it expects to find working

Beyond the safety case, the Regulator expects the routine duties of a high-rise residential building to be functioning. The Fire Safety (England) Regulations 2022, in force 23 January 2023, set several that leave a clear evidential trail.

• External wall system information and floor plans shared electronically with the local fire and rescue service.
• Hard-copy floor plans and a single-page orientation plan, with responsible person contact details, kept current in a secure information box.
• Monthly checks of firefighters' lifts and key firefighting equipment, recorded.

Monthly checks are the duty most likely to slip, precisely because they are frequent and unglamorous. A gap in the record of monthly lift checks is exactly the kind of small, factual failure an inspection surfaces. We cover the cadence in monthly checks that keep a high-rise compliant.

Residents are part of the picture

The Act expects an Accountable Person to give residents a way to raise building safety concerns and to respond to them. The Regulator can look at whether that system exists, whether concerns are logged, and whether they are answered and fed back into the safety case. A building with no record of resident concerns is not necessarily a building with no concerns; it may simply be one that is not capturing them, which is its own finding.

What "good standing" tends to look like

It is hard to reduce occupation-phase oversight to a checklist, but the buildings that fare well share recognisable habits.

None of these requires heroics. They require the building's record to be kept current as a matter of routine, so that when the question comes, the answer is already on file.

The quiet advantage of being ready

The buildings that find occupation-phase oversight stressful are usually the ones that treat compliance as something to be produced on demand. The buildings that find it manageable treat it as something they maintain, so a request from the Regulator is a matter of retrieval rather than reconstruction. The difference is not effort spent in the moment; it is effort spread evenly, in advance.

SAMRISK is built for that even spread. Assessments are dated and owned, statutory checks sit on a compliance calendar that chains its own deadlines, remedial actions are tracked to closure, and the whole history of a building stays in one searchable place, so being ready is the default state rather than a project. You can see how it fits on the compliance calendar and safety case pages. This is general guidance rather than legal advice, and the current expectations of the Regulator should be confirmed directly before acting on any specific point.
