In short: Mandatory occurrence reporting is the duty on the Principal Accountable Person (PAP) of an occupied higher-risk building to report prescribed safety occurrences - structural safety or spread-of-fire risks that could realistically cause death or serious injury - to the Building Safety Regulator (BSR). It is a duty under the Building Safety Act 2022 and the regulations made under it.
Who must report?
The Principal Accountable Person for an occupied higher-risk building. The PAP must also put in place a mandatory occurrence reporting system so that relevant safety information reaches them and can be assessed.
What is a reportable occurrence?
Broadly, a structural-safety or fire-safety event - or a situation that could lead to one - that, if realised, could cause a significant number of deaths or serious injury to a number of people. Examples include serious structural failures or fire-safety failures affecting the building's safety.
Timescales and process
Reportable occurrences must be notified to the BSR promptly, with a fuller report following. The PAP must keep records of occurrences and reports as part of the golden thread.

Mandatory occurrence reporting. It is a mouthful, but the idea is straightforward, and getting it wrong is serious. The duty falls on the principal accountable person of an occupied higher-risk building. They must also put a reporting system in place, so that safety information actually reaches them and can be assessed. A reportable occurrence is a structural or fire-safety event, or a situation that could lead to one, which could realistically cause death or serious injury to a number of people. Reportable occurrences must be notified to the Regulator promptly, with a fuller report to follow. And records of occurrences and reports are kept as part of the golden thread. CTS helps you set up a compliant reporting system, judge whether an event is reportable, and make the report, all logged in the CTS BuildSafe platform. The full guide is on our website.
