The Innovation Unit and batching: how the BSR got fast
The Innovation Unit is the BSR's dedicated route for new-build Gateway 2 applications. In the 12 weeks to 1 August 2026, the BSR decided 45 new-build or conversion applications: 91% were approved and the median determination time was 22 weeks. External specialists work under BSR oversight while the regulator retains the decision.
Why did the BSR need new machinery?
The original model asked a young regulator to assess some of the most complex building control applications in the country with the multi disciplinary capacity it had, and the queue answered for it: roughly 200 decisions in the first quarter of 2025 while applications piled up, and average waits of 43 weeks by that October. Capacity, not policy, was the constraint, and the June 2025 reset attacked it from two directions.
How does the Innovation Unit work?
The Innovation Unit is the BSR's dedicated lane for new-build Gateway 2 applications, built in the reset to process them with focused teams and standardised expectations. Its results are the sharpest evidence in the regime that preparation quality drives outcomes: in the twelve weeks to 1 August 2026 the BSR approved 91% of the 45 new-build and conversion applications it decided, with a 22-week median. Haymarket in Bristol, the city's tallest tower at 29 storeys with 442 student beds, went through the unit to a February 2026 approval, and it is exactly the profile the lane favours: a substantial, professionally assembled, fully resolved submission.
How does batching work?
Batching accepts that the scarce resource is specialist assessment, and buys it at scale: applications are bundled and sent to external specialist engineering assessors, fire and structural, working under BSR oversight and to BSR standards, with the regulator keeping the decision. Piloted between September and December 2025, it is the single biggest reason quarterly throughput more than tripled. Use the latest category-specific timescales for programme planning: the current 22-week new-build median remains above the statutory 12 weeks. December 2025 also extended staged applications to single-tower schemes, letting groundworks start while superstructure packages sit in the batching flow.
How do you route your application into the fast machinery?
You build the application these processes are designed to consume. External assessors working to a standard model reward standard structure: the CLC guidance notes' folder structures and information schedules, a complete document set that survives validation first time, and a design resolved to the point where an assessor never has to ask what you intended. Engage the BSR pre-application so routing and contentious points are settled before the clock starts, and treat the application guide as the baseline checklist. The fast lanes exist; complete, resolved, well-organised submissions are the ticket into them.
Frequently asked questions
- What is the BSR Innovation Unit?
- A dedicated route created in the June 2025 reset for processing new-build Gateway 2 applications. In the 12 weeks to 1 August 2026, the BSR decided 45 new-build and conversion applications, approving 91%, with a median determination time of 22 weeks.
- What is batching?
- The model, piloted between September and December 2025, in which the BSR bundles applications out to external specialist engineering assessors working under its oversight. It broke the assessor-capacity bottleneck: quarterly decisions rose from roughly 200 to more than 700, with batching medians of 12 to 14 weeks.
- Can I choose to go through the Innovation Unit?
- You cannot simply tick a box, but you can make your application the kind these routes exist for: a new-build scheme with a complete, well-structured, fully resolved submission. Pre-application engagement with the BSR is the practical channel for understanding how your scheme will be routed.
