Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, with reference to Section 21 of The Building (Higher-Risk Buildings Procedures) (England) Regulations 2023, how many change control applications were (a) received and (b) approved in 2025 by the Building Safety Regulator; and what was the average time taken by the regulator to approve the applications.

The Building Safety Regulator (BSR) can confirm that in 2025 there were 159 Regularisation Applications received with 47 approvals being delivered. The average time in which an approval was made was 33 weeks.

In 2025 BSR received 2335 Completion Certificate Applications, granting 664 approvals. The average time in which an approval has been made was 28 weeks.

The BSR can confirm that in 2025 there were 514 Change Control requests received with 148 of these marked as complete. The average time taken by the BSR to approve the applications cannot be determined as the Change Requests do not have a definitive outcome date.

Last June, MHCLG announced a new phase for the BSR, including strengthened leadership, steps to address operational challenges to speed up decision making, and plans for a new body for the BSR.

Enhanced operating models are delivering significant progress. A new Innovation Unit has dramatically reduced processing time for new build applications, with the highest quality applications approved within the 12-week target, whilst the BSR continues to make strong headway tackling cases already in the system.

BSR continue publish performance data monthly to support transparency and accountability.
