The Building Safety Regulator’s (BSR) handling time for each application is dependent on a range of factors, primarily the quality of the application and the additional information submitted by the applicant. As can be seen in the table below, the average handling time by hour varies.

Information on the length of documents submitted as part of applications is not something the BSR actively collects data for.

The BSR is actively supporting the Construction Leadership Council to develop and publish a further suite of industry guidance on the statutory documents accompanying building control approval applications, staged approvals for single tower HRBs and construction phase and gateway three (completion certificate stage). This is expected in November.

The BSR has also published four new pieces of guidance, including:
