Building Safety Regulator Issues Mandatory Digital Occurrence Reporting Guidance for Commercial Duty Holders
The Building Safety Regulator has published explicit clarification on mandatory occurrence reporting timelines: commercial landlords and responsible entities must lodge specified safety occurrences within 48 hours.

Estates directors cannot delegate ultimate statutory liability to third-party managing agents without contemporaneous digital audit trails.
The Building Safety Regulator (HSE) has issued formal technical guidance concerning mandatory occurrence reporting (MOR) procedures across multi-tenanted commercial and mixed-use premises.
Under the regulations, structural envelope defects, unrecorded fire compartmentation penetrations, and catastrophic M&E plant failures must be formally logged within 48 hours of initial detection.
Managing agents are required to integrate digital occurrence registers with the building’s persistent Golden Thread repository to maintain valid building insurance and avoid formal improvement notices.
