Who must apply for a building assessment certificate (BAC)
The principal accountable person (PAP) for a high-rise residential building must apply for a BAC when told to do so by the Building Safety Regulator (BSR).
When BSR tells you to apply for a BAC, you have 28 calendar days to submit your application.
If you do not submit your BAC application by the deadline:
you are in breach of your duties
BSR can take enforcement action in line with its enforcement policy statementontheHealthandSafetyExecutive(HSE)website.
After the building is registered
A high-rise residential building does not need a BAC before people can live in it.
The length of time between registering the building with BSR and being asked to apply for a BAC depends on the building information supplied at registration. The buildings currently prioritised for a BAC meet at least one of the following criteria, they are:
18 metres to 29.99 metres high with more than 378 residential units
over 30 metres high with more than 11 residential units
clad with combustible aluminium composite material
large panel systems built between 1957 and 1973 with a gas supply, and it is unclear if reinforcement work has been carried out
After submitting the BAC application, BSR may ask you:
to provide additional records or other documents
for a meeting, either virtual or in person, to discuss parts of your application or the management of building safety risks
to provide a demonstration of systems used to manage building safety risks, for example maintenance of control measures
BSR will make reasonable efforts to work with you, gather more information and hold discussions before determining the outcome of your application.
Other information you must provide
For the BAC application, you must provide serial numbers of any compliance notices issued by BSR that are currently in force. This includes compliance notices issued to you or other accountable persons for the building.
Payment information
You will need to provide payment card or invoice details to pay:

a brief description of the update
the reason for making the update
BSR may ask you to provide the updated safety case report. There is a charge you will need to pay if BSR decides to review the updated safety case report. This is set out in the BSR charging scheme ontheHSEwebsite..
Application decisions
Approved
BSR will provide you with a BAC when it is satisfied you’re meeting the legal duties of a PAP under Part 4 of the Act.
You must display the BAC in a prominent place in the building where residents can easily see it, such as a shared lobby.
Action is needed to correct issues with your application
If there are issues with your application that can be fixed promptly, BSR may give you the opportunity to fix the issues.
BSR will tell you the issues you need to fix and the deadline you must fix them by.
If you fix the issues by the deadline, BSR may provide you with a BAC. If you do not fix the issues by the deadline, BSR will refuse your BAC application.
Refused
BSR will refuse a BAC application when it is not satisfied you’re meeting the legal duties of a PAP under Part 4 of the Act.
BSR will send you either a contravention letter or a compliance notice telling you:
why the application is refused
the issues you need to fix and the deadline you must fix them by
If you receive a compliance notice you must display it in the building where residents can easily see it, such as a shared lobby.
You must provide evidence to BSR that you have fixed the issues set out in the letter or notice, by the deadline. BSR will tell you when to re-apply for a BAC.

Request a review of a decision
If you disagree with your BAC application decision, you can request a review. BSR will tell you how to request a review when it sends you the application decision.
If after the review you still disagree with the decision, you can appeal to a First-tier Tribunal.
