Building Safety Act Secondary Legislation: What Commercial FM Duty Holders Must Verify Before Q4

The transition period for mandatory digital occurrence reporting and safety case submissions is closing for mixed-use and higher-risk estates. Here is how leading FM operations desks are auditing their statutory evidence registers to eliminate personal duty-holder exposure.

Under the Building Safety Act 2022 and its associated secondary statutory instruments, the legal framework governing commercial and mixed-use real estate has shifted from periodic post-hoc audits to continuous, contemporaneous safety governance. For facilities managers, property directors, and designated Responsible Persons, the operational implications are non-negotiable.

Crucially, statutory liability cannot be contractually assigned away to a managing agent or hard FM subcontractor. If unrecorded fire compartment penetrations or uncertified M&E remedials occur on site, the statutory duty holder remains strictly liable.

1. The 48-Hour Digital Occurrence Reporting Requirement

Mandatory Occurrence Reporting (MOR) requires specified safety-critical events—including failure of structural elements, uncontained fire spread, or simultaneous failure of active life safety systems—to be logged and submitted to the Building Safety Regulator. FM helpdesks must ensure their incident escalation protocols reflect this compressed timeline.

  • Emergency generator and central battery failure during power outage test
  • Breach of primary compartmentation during mechanical ductwork installation
  • Wet riser pressure loss or isolation valve seizure exceeding 4 hours
  • Uncontrolled refrigerant discharge in occupied enclosed plantrooms

2. Golden Thread Data Interoperability

A digital Golden Thread is not a folder of unindexed PDF scans on a local server. The Regulator expects machine-readable, spatially indexed asset records that persist seamlessly across changes in managing agent or facilities management provider. When equipment is repaired, decommissioned, or modified, the change must be reconciled in the CAFM within 48 hours.

DUTY HOLDER DIRECTIVE: Require all incoming contractors to supply geolocated photo evidence, commissioning sheets, and third-party accreditation certificates (e.g. FIRAS, NICEIC, BESA) before closing any remedial work order.
