The regulation

What the law asks.

Building Safety Act 2022, for occupied higher-risk buildings in England.

  • Assess the building safety risks: fire spread and structural failure.
  • Take all reasonable steps to prevent a major incident and to reduce its severity.
  • Prepare a safety case report and give it to the Building Safety Regulator when asked.
  • Keep the golden thread of information up to date.
  • Run a mandatory occurrence reporting system.

General information as at October 2026. Not legal advice; check the regulation or ask a competent person.

Questions.

What does HRB mean and is my building one?

A higher-risk building under the Building Safety Act 2022: at least 18 m tall (measured from ground level to the floor of the top storey) or at least 7 storeys, with at least 2 residential units. SAMRISK records the classification but does not make the legal decision, so confirm with the BSR if you are unsure.

Do I have to use bow tie analysis?

No. Bow tie analysis is built in for teams that use it. Major hazard reports can stand on their own, and bow ties link to them but are not required.

How does mandatory occurrence reporting work?

When you create an incident, mark it as a mandatory occurrence report and pick a category. SAMRISK sets two deadlines from the incident date: the notice to the Building Safety Regulator within 10 days, and the full report within 10 days of that. The law counts from when you became aware of the occurrence, so check the dates if that was later. The incident page tracks what has been submitted, and overdue reports show on the building overview.

What is the golden thread and how does SAMRISK keep it?

The golden thread is the accurate, up-to-date record of a building and its safety information. SAMRISK keeps every version of every document and an append-only history for each record, so you can show what was known and when.

Are PEEPs visible to everyone?

No. Personal emergency evacuation plans contain personal data, so only managers and admins can view the PEEPs page. Handle it under UK GDPR and the data sharing rules in your resident engagement strategy.

Do I have to refresh the safety case report every time something changes?

Mark a change request as a material change. When it is completed, SAMRISK flags the safety case for refresh. Other changes leave the current report in place until your normal review.
