Design and construction

The Building Safety Bill is making its way through Parliament. As it passes, we will get a clearer idea of what it might mean to the building safety reforms. We will share information as we learn more.

Before starting any building work, applicants will need to submit a design application to BSR. The application will include information that shows how the design will:

The application will need to show the assumptions that have been made about the occupied building once built. Any assumptions and proposals must be reasonable and justified

During construction

Building work must not start until approved by BSR.

Some changes in design may need further approval from BSR before works can proceed.

When the building is completed

At completion, BSR will:

On approval, BSR will issue a completion certificate.

Before occupation

After a completion certificate is issued, the building will need to be registered. An application to register the building should be made to BSR.

Residential units must not be occupied until the building is registered.

Developments that are built in stages

Any proposals for phased construction or occupation should be agreed at the design stage.

Construction work should not start on a phase or stage without approval from the BSR.
