The Building Safety Regulator’s first Gateway 2 performance update of 2026, published on the day it formally became a standalone body, provides the clearest operational picture yet of how the regime is functioning in practice.
While headline figures point to rising approval volumes and improving throughput, the underlying data tells a more complex story. London now accounts for 68% of all Gateway 2 decisions, making the capital the primary stress-test environment for the Building Safety Act regime. At the same time, high validation failure rates, persistent application quality issues, and an explicit reassessment of legacy cases signal that tolerance within the system is narrowing.
For dutyholders, this update is not about momentum. It is about where risk now sits, how approval decisions are being shaped, and why early-stage failures remain the dominant cause of delay.

London Has Become the Centre of Gateway 2 Decision-Making
Between November 2025 and late January 2026, the BSR issued 476 Gateway 2 decisions in London, representing more than two-thirds of all decisions nationally.
This concentration matters. London schemes are now effectively defining how Gateway 2 is interpreted, enforced and benchmarked. Design approaches, evidence standards and decision outcomes emerging from London cases are already functioning as informal precedent for other regions.
For project teams operating in the capital, this means Gateway 2 scrutiny is not theoretical. It is being actively refined in real time, with limited scope for programme-led negotiation.

Decisions Are Increasing — But Live Risk Remains High
Across all application categories, the BSR recorded 698 Gateway 2 decisions in the 12 weeks to 24 January, with 1,159 live applications still in the system. These live cases represent more than 37,000 residential units.
While approval volumes are rising, this does not equate to reduced regulatory exposure. A growing pipeline of live cases means more projects remain in regulatory limbo, with design freeze pressure, procurement risk and commercial uncertainty concentrated at Gateway 2.
The system is moving faster, but it is not becoming looser.

Validation Failure Is Still the Primary Bottleneck
One of the most telling metrics in the update sits outside the headline approval numbers. Within the Innovation Unit, 56% of applications fail at the initial validation stage, often due to missing or incomplete basic design information.
This confirms a pattern already visible on live projects. Gateway 2 delay is rarely caused by complex engineering disagreement. It is more often caused by:
From a regulatory perspective, these are not technical issues. They are competence and coordination failures.

This confirms a pattern already visible on live projects. Gateway 2 delay is rarely caused by complex engineering disagreement. It is more often caused by:
- incomplete fire and structural strategies
- unclear dutyholder accountability
- inconsistent design information across submissions
- failure to demonstrate compliance in a traceable, auditable format
From a regulatory perspective, these are not technical issues. They are competence and coordination failures.
Approval Rates Highlight a Narrowing Acceptance Window
Of Innovation Unit cases that progress beyond validation, only 30% are approved, with 41% rejected and the remainder held in extended information resolution.
This data reinforces an uncomfortable truth for the industry. Passing validation is not the hard part. Demonstrating a coherent, compliant and defensible safety case remains the real test.
The regulator’s stated objective is not to increase approval rates at any cost, but to improve approval rates for safe applications. That distinction is critical.

Legacy Applications Are Reaching a Decision Point
The update confirms that 52 legacy cases submitted under the previous model have been closed since November, with a further 29 complex cases now under active review to determine whether they should be rejected and resubmitted.
This signals a shift in regulatory posture. BSR is no longer prepared to indefinitely resource historic applications that cannot be brought to a compliant standard. Where schemes cannot demonstrate viability under the current regime, rejection and reset is now being openly considered.
For dutyholders carrying legacy risk, this represents a material turning point.

Batching and External Engineering Review Are Now Structural
The BSR confirms that its batching pilot, using specialist engineering suppliers under regulatory oversight, has moved from trial to core workflow component.
This has practical implications. Gateway 2 assessment is becoming more standardised, more comparative, and less receptive to bespoke narrative arguments unsupported by structured evidence. Consistency, traceability and alignment across submissions are now decisive factors.
Projects relying on informal interpretation or fragmented consultant inputs are increasingly exposed.

What This Means for Dutyholders in 2026
This update reinforces a clear regulatory direction.
Gateway 2 is no longer the slowest part of the system. Poor-quality submissions are.
London projects will continue to carry disproportionate scrutiny, and decisions made in the capital will shape national enforcement norms. Validation failure remains the single largest risk driver, and legacy patience is visibly running out.
For dutyholders, the priority is no longer understanding what Gateway 2 requires. It is proving, with discipline and consistency, that those requirements have been met — in a way that withstands formal regulatory audit.
Conclusion
The BSR’s January 2026 data does not describe a system in transition. It describes a system settling into enforcement. Approvals are rising, but tolerance is narrowing. Decisions are faster, but expectations are firmer. And London has become the proving ground where the Building Safety Act is being operationalised in practice.
For those submitting Gateway 2 applications in 2026, the message is clear: success now depends less on timing and more on evidence.
