Gateway 2 Approval Index
The Gateway 2 Approval Index is a London Construction Magazine intelligence tracker monitoring Building Safety Regulator decision patterns, approval rates, London case concentration, residential units affected and operational delivery signals under the Building Safety Act regime. The index is designed for contractors, developers, consultants, dutyholders, project managers and commercial teams who need to understand how Gateway 2 performance is changing and what those changes mean for construction delivery. While many project teams focus only on whether Gateway 2 approvals are rising or falling, London Construction Magazine analysis tracks a wider operational pattern: approval rate, decision volume, London concentration, live case pressure, remediation movement, Innovation Unit performance and batching behaviour.
Current Index Snapshot
Approval Rate Timeline
| Reporting Period | Approval Rate | Determinations / Units | LCM Operational Interpretation |
|---|---|---|---|
| 2024 Transitional Period | Substantially lower initial rates | Gateway 2 regime entering live statutory operation | The early Gateway 2 market exposed widespread misunderstanding of evidence architecture, dutyholder coordination and design maturity requirements. |
| Early 2025 | ~60–65% | Significant proportion of applications queried or returned | The industry was still adapting operationally to BR Principal Designer obligations, golden thread expectations and evidence sequencing standards. |
| Late 2025 | Mid-60% range | Rapid increase in Gateway 2 submissions nationally | Submission quality became the dominant programme risk as development teams accelerated applications ahead of funding and procurement milestones. |
| 1 May 2026 release | 71% | 323 decisions · 17,046 units determined | Approval performance was improving, but live case pressure and remediation delays remained major delivery constraints. |
| 30 May 2026 — latest release | 75% | 358 decisions · 14,928 units determined · 9,499 units approved | The latest BSR data shows a clear improvement in approval rate and decision throughput, with approvals rising across all Gateway 2 categories while London remains the dominant case concentration. |
Current Snapshot — 12 Weeks to 30 May 2026
| Category | Approval Rate | Key Figure | LCM Operational Interpretation |
|---|---|---|---|
| All Categories — National | 75% | 358 Gateway 2 decisions | The national approval rate has moved upward from the previous 71% position, indicating improved throughput but not a return to low-friction pre-Building Safety Act delivery. |
| Residential Units Determined | 64% | 14,928 units determined · 9,499 units approved | Unit approvals remain below the headline case approval rate, showing that approval performance must be read through both application count and housing-unit impact. |
| New Residential Unit Applications | — | 13,964 new residential units received | Determined units exceeded newly received units during the period, which is a positive signal for backlog management and delivery flow. |
| Live Units in Active Cases | — | 38,775 units in progress | The live residential-unit pipeline remains the clearest signal that Gateway 2 continues to influence housing delivery, funding confidence and contractor mobilisation timing. |
| London Share of Decisions | 65% | 65% of all Gateway 2 decisions related to London cases | London remains the national pressure point for Gateway 2, meaning UK-wide BSR performance continues to be heavily shaped by capital-based higher-risk building activity. |
| London Application Movement | — | 472 London applications closed · 436 new London applications received · 894 live London applications | London closures exceeded new receipts during the period, but the live London caseload remains substantial and continues to create delivery-risk exposure. |
| Innovation Unit — National | 90% | 31 decisions · 28 approvals · 43 all-time approvals · 22-week median approval time | The Innovation Unit is now showing materially stronger approval performance, suggesting that complex cases are moving where applicants can resolve technical evidence issues through structured engagement. |
| Innovation Unit — London | 100% | 19 London decisions · 19 approvals | London Innovation Unit approvals were 100% in the period, but this should be read as the result of intensive case engagement rather than reduced regulatory scrutiny. |
| Innovation Unit Live Pipeline | — | 131 live IU applications · 30,369 units · 66% of IU applications based in London | The Innovation Unit is still structurally London-heavy, reinforcing the capital’s role as the main test environment for complex HRB approval delivery. |
| External Remediation | 79% | Approval rate over the latest rolling 12-week period | Remediation approval performance has moved above the BSR’s 65% minimum target for 2026, indicating that the external remediation improvement plan is beginning to show measurable operational effect. |
| Legacy Remediation Cases | — | 16 legacy 2024 applications remain, down from 42 at the start of 2026 | The reduction in older remediation cases is a positive signal, but BSR notes that average approval time remains skewed by work to close out older 2024 and 2025 applications. |
| Average Remediation Approval Time | — | 39 weeks in the rolling 12-week period | The 39-week average remains a major programme variable, even where approval rates are improving, because older legacy cases continue to distort headline timing. |
| Batching Process | — | 12–14 weeks median from supplier issue to decision, depending on application type | Batching is now a significant operational mechanism for backlog resolution, but it remains dependent on BSR oversight and the quality of submitted evidence. |
LCM Index Reading
The latest Gateway 2 data shows a regulator moving more cases through the system, with the national approval rate rising to 75% and 358 decisions made in the 12 weeks to 30 May 2026. The most important operational signal is not simply that approvals are rising, but that decisions, unit determinations, Innovation Unit outcomes and remediation approval rates are all improving at the same time.
For contractors and developers, the issue is still not limited to whether the Building Safety Regulator is slow. The stronger question is whether a project’s design maturity, evidence ownership, Golden Thread structure and consultant coordination are sufficient to avoid revision loops, procurement drag and programme uncertainty. A 75% headline approval rate still means one in four decisions is not a straightforward approval.
London remains the central pressure point. With 65% of all Gateway 2 decisions relating to London cases and 894 live London applications still in progress, the capital continues to shape national Gateway 2 performance. For London-based higher-risk building schemes, the approval environment is improving, but regulatory evidence quality remains a live commercial and programme risk.
Evidence-Based Summary
Gateway 2 improvement is not driven by a single factor but by a combination of higher decision throughput, stronger Innovation Unit engagement, remediation process changes and batching-led assessment capacity. While the latest BSR figures show the approval rate rising to 75%, the evidence also shows that London remains the dominant concentration of Gateway 2 activity and live case pressure. In practical terms, contractors and developers should treat Gateway 2 as an improving but still material pre-construction risk that depends heavily on evidence quality, design maturity and dutyholder coordination.
Why This Index Matters
Gateway 2 approval performance affects more than regulatory administration. It influences procurement timing, contractor mobilisation, consultant workload, client funding confidence, remediation sequencing and the commercial viability of higher-risk building delivery.
London is especially exposed because the capital continues to represent the majority of recent Gateway 2 decision activity. This means national approval trends are also London delivery-risk indicators.
Methodology
The Gateway 2 Approval Index uses publicly available Building Safety Regulator building control approval application data, regulator updates and London Construction Magazine analysis.
The index tracks:
- Gateway 2 decision volume;
- overall approval rate;
- residential units determined and approved;
- live case load;
- London share of decisions;
- Innovation Unit decision activity;
- external remediation progress;
- legacy remediation case movement;
- approval timing and batching signals.
The index does not provide legal, design, engineering or regulatory advice. It is an editorial intelligence tracker designed to interpret public approval data and explain operational consequences for the construction sector.
