Operating a mandatory occurrence reporting system
How principal designers, principal contractors and principal accountable persons must set up and maintain a system to report building safety incidents and risks.
Applies to England
Who must operate a mandatory occurrence reporting system
Principal designers and principal contractors
The principal designer and principal contractor must establish and operate a mandatory occurrence reporting (MOR) system, during:
- construction of a new higher-risk building
- work on an existing higher-risk building, unless the work consists only of exempt work or emergency repairs
- work

A higher-risk building is a building that has at least:
- 7 storeys or is at least 18 metres high
- 2 residential units or is a hospital or a care home
You can read guidance about the criteria that makes a building a higher-risk building.
Principal accountable persons (PAPs)
A higher-risk building with at least 2 residential units must be registered with the Building Safety Regulator (BSR) as a high-rise residential building before people live there.
Principal accountable persons
The principalPAP accountable person must must:
- establish and operate a single MOR system for the high-rise residential building they are responsible
for.for - make sure there are regular reviews of the system so it remains effective
When BSR tells the PAP to apply for a building assessment certificate, the PAP must submit information about the MOR system. The information must show that the system allows:
- reporting and recording of safety occurrences to the accountable person (AP)
- recording of safety occurrences identified by the AP
- assessment of safety occurrences to determine whether they are a safety occurrence
- BSR to be notified of safety occurrences as soon as possible
- safety occurrences to be reported to BSR within 10 days
Systems operated by the principal designer and principal contractor
The principal designer and principal contractor must:
- establish and operate an MOR system before construction or building work begins
- maintain and operate their system throughout the project
Principal designers and principal contractors can operate the same, or separate MOR systems.
Your MOR system must enable prompt reporting by:
- designers and contractors working on the project
- others who periodically visit the work site

Reportable incidents and risks
Your system must let people report building safety incidents and risks that have caused, or if not remedied are likely to cause:
- the death of a significant number of people
- serious injury to a significant number of people
Building safety incidents and risks involve at least one of the following:
- structural failure of the building
- the spread of fire or smoke in the building
For design work, a building safety risk is an aspect of the design related to structural integrity or fire risk, which if built could cause death or serious injury to a significant number of people.
You must report incidents or risks that meet these criteria to BSR as a safety occurrence. You must do this by submitting a mandatory occurrence:
noticenotice, as soon as you canreportreport, within 10 days of the safety occurrence being identified
Operating the MOR system
To help identify building safety incidents and risks, frequent inspections of the:
- design work must be set up by the principal designer
- building work must be set up by the principal contractor
You must:
- promptly review the reports submitted on the system
- decide if any action is needed
What you must tell people
You must share information about how the system works with:
- designers, contractors and others working on the project, before they begin any work
- anyone who enters the work site, as soon as possible
- BSR, when requested
You should tell people:
- what they need to report
- how to make a report
- how and when the report will be dealt with
- when they should expect a response about a report they have made
- how you’ll collect and store information in line with General Data Protection Regulation (GDPR)
It may be helpful to include examples of what people should report on your mandatoryMOR occurrence reporting system.
Systems operated by the principal accountable personPAP
As the principalPAP, accountable person, you must establish and operate an MOR system for the building when it is occupied by residents. You must review the system regularly to ensure it remains effective.
Your system must enableallow promptquick reporting by:
- all residents
accountablepersonsAPs- others who use the building
Reportable incidents
Your system must let people report building safety incidents that have caused, or if not remedied are likely to cause:
- the death of a significant number of people
- serious injury to a significant number of people
Building safety incidents involve at least one of the following:
- structural failure of the building
- the spread of fire in the building
The relevant accountableAP person must report incidents that meet these criteria to BSR as a safety occurrence. They must do this by submitting a mandatory occurrence:
noticenotice, as soon as they canreportreport, within 10 days of the safety occurrence being identified
Complaints system
Residents and others may be concerned about something that could cause a building safety incident in the future,future and submit it on your complaints system.
If a concern submitted on your complaints system meets the criteria of what to report to BSR as a safety occurrence, the relevant accountableAP person must:
- identify it as soon as possible
- submit a mandatory occurrence notice and report to BSR within 10 days of the safety occurrence being identified
Operating the MOR system
For the parts of the building they are responsible for, the accountableAPs persons must:
- promptly assess the reports submitted on the system
- decide what action is needed
What you must tell people
You must share information about how the system works with:
- all residents
accountablepersonsAPs- other users of the building
-
BSR, when requested and as part of applying for a
BuildingbuildingAssessmentassessmentCertificatecertificate
To share the information about how the system works, you should publish a policy which tells people:
- what they need to report
- how to make a report
- how and when the report will be dealt with
- how they can request an update about a report they have made
- how you’ll collect and store information in line with General Data Protection Regulation (GDPR)

You’ll need to describe how and when incidents that have been reported on the system will be submitted to BSR as a mandatory occurrence notice and report.

Involving residents
