Eighty-seven percent. That is the approval rate the Building Safety Regulator posted for Gateway 2 decisions in the twelve weeks to 5 October 2026, a figure that would have seemed implausible a year earlier, when approvals for new higher-risk buildings sat at just 39%. The data, released on 6 October 2026 and reported by London Construction Magazine, confirms a genuine acceleration in building control decisions across the capital. But for anyone who owns, leases, or is developing a flat near one of these projects, the real story is timing, and specifically, how Building Safety Regulator Gateway 2 approvals London party wall October 2026 interact with each other matters far more than most people realise.
London accounts for 60% of the national live new-build pipeline and nearly two-thirds of all live internal refurbishment cases. That concentration means thousands of leaseholders and adjoining owners across the city are about to find themselves inside, or next door to, a Gateway 2-approved project. Understanding the overlap between Gateway 2 and the Party Wall etc. Act 1996 is no longer a niche legal point, it is becoming a mainstream property concern.
Key Takeaways
- Gateway 2 approval rates hit 87% nationally for the 12 weeks to 5 October 2026, up from 77% in June and 84% in August, with 20,471 residential units cleared.
- London’s new higher-risk building approvals ran at 97%, with a 22-week median determination, faster than the national 23-week figure.
- Higher-risk building applications surged from 12 in June to 64 in September 2026, which the BSR links to the Building Safety Levy taking effect on 1 October 2026.
- Because Gateway 2 can take 20 to 35 weeks, party wall notices, awards and schedules of condition should be progressed in parallel, not after approval lands.
- Awards commonly require works to begin within 12 months, so programme slippage during Gateway 2 review can put that window at risk.
What the October 2026 Gateway 2 Figures Actually Show
The BSR’s twelve-week snapshot to 5 October 2026 is the clearest evidence yet that building control decisions are moving faster and more favourably for applicants than at any point since the regime began.
| Category | Decisions / Approved | Approval Rate | Median Time |
|---|---|---|---|
| All Gateway 2 (national) | 378 / 330 | 87% | varies by category |
| New HRBs and conversions (national) | 57 / 55 | 96% | 23 weeks (34 for complex) |
| New HRBs and conversions (London) | 37 / 36 | 97% | 22 weeks |
| Remediation (national) | 110 / 96 | 87% | 32 weeks (22 for 2026 apps) |
| Remediation (London) | 54 / 52 | 96% | , |
| Internal refurbishment (A and B) | 185 / 158 | 85% | 31 weeks (21 for 2026 apps) |
London’s live pipeline is substantial: 111 new-build applications covering 22,204 units, 180 live remediation cases covering 14,298 units, and 749 of the 1,109 national live internal refurbishment cases. Nineteen of the thirty live highly complex design cases nationally sit in London, carrying a 35-week median.
The BSR also recorded a sharp rise in higher-risk building application intake, from 12 in June to 17 in July, 34 in August and 64 in September 2026, which it attributes to developers moving before the Building Safety Levy took effect on 1 October 2026. The regulator has activated contingency and triage measures in response, and has reiterated that it “remains clear that materially sub-standard applications can be rejected where there is no realistic path to approval.”
Why Gateway 2 Projects Trigger the Party Wall Act
A higher-risk building, in the BSR’s definition, is at least 18 metres tall or has seven or more storeys and contains two or more residential units. Gateway 2 is the building control approval stage these projects must pass before construction can proceed.
What often gets overlooked is that Gateway 2 approval and party wall compliance are two entirely separate legal processes. Works on or near a higher-risk building, recladding, remediation, internal refurbishment, basement excavation, or extensions on an adjoining site, routinely fall within sections 1, 2 and 6 of the Party Wall etc. Act 1996. These sections cover new walls on the boundary, work to an existing party wall or structure, and excavations near a neighbouring building or structure.
Section 1 and section 2 notices require one month’s notice; section 6 notices for excavation work require two months. None of these notice periods are tied to when Gateway 2 approval is granted. A building owner can, and generally should, serve party wall notices well before building control sign-off arrives.
Why Timing Matters: Gateway 2 Delays Versus Party Wall Deadlines
With national median determination times ranging from 22 weeks for straightforward new London HRBs to 35 weeks for highly complex live cases, and internal refurbishment running at 21 to 31 weeks, there is a real mismatch between how long Gateway 2 review takes and how long a party wall award typically remains valid.
Party wall awards commonly require works to begin within roughly 12 months of the award being served. If a developer waits for Gateway 2 approval before even serving notice, and that approval then takes 30-plus weeks, the subsequent process of agreeing an award, arranging a schedule of condition and mobilising contractors can quickly eat into that 12-month window, particularly on the complex London schemes where 35-week medians are now typical.
The sensible approach, and the one this practice recommends to clients, is to run the two processes in parallel:
- Serve notices under the relevant sections of the Party Wall Act as soon as design information is sufficiently fixed, without waiting for Gateway 2 sign-off.
- Agree the party wall award and complete schedules of condition while Gateway 2 review is ongoing.
- Build in contingency, recognising that BSR’s own major change request data shows even “closed” changes take a 7-week median against a 6-week statutory target.
What Adjoining Owners in London Blocks Should Expect
Leaseholders in blocks adjacent to a higher-risk building project should expect a notice to arrive at some point during, not necessarily after, the Gateway 2 process. Given that 749 of the UK’s 1,109 live internal refurbishment cases sit in London, and that remediation activity in the capital is running at a 96% approval rate across 180 live cases, the odds of receiving a notice are rising steadily for anyone in or near a converted or remediated block.
Adjoining owners have the right to appoint their own surveyor, request a schedule of condition before works start, and have their surveyor’s reasonable fees covered by the building owner. Guidance on what a party structure notice means and how to respond is a useful starting point for anyone unsure of their position.
What This Means for You
Whether a project is a new higher-risk build, a remediation scheme, or an internal refurbishment inside an existing block, Gateway 2 approval and party wall compliance now need to be managed side by side rather than sequentially. This practice provides party wall surveyor services across every London borough, including dedicated coverage in South London, East London, North London, West London and Central London.
For developers and contractors, that means serving notices early, securing awards before Gateway 2 clearance lands, and building realistic contingency into programmes so the 12-month works window in an award is not wasted waiting on building control. For flat owners and leaseholders, it means understanding that a notice arriving while Gateway 2 is still under review is normal, not premature, and that adjoining-owner representation protects your interests regardless of where the building control process stands. Those wanting to understand likely fees before engaging a surveyor can review how party wall costs are structured and practical ways to keep those costs down.
Frequently Asked Questions
Does Gateway 2 approval replace the need for a party wall award? No. Gateway 2 is a Building Safety Regulator building control approval. A party wall award under the 1996 Act is a separate legal requirement whenever notifiable work affects a shared wall, structure, or nearby excavation.
Can I serve a party wall notice before Gateway 2 approval is granted? Yes, and it is usually advisable. Notice periods of one or two months, plus award negotiation, can take considerable time, so starting early helps avoid delay once Gateway 2 clears.
What happens if Gateway 2 review overruns the party wall award’s start deadline? Awards commonly require works to begin within around 12 months. If Gateway 2 review pushes beyond that, the award may need to be revisited or a new one agreed before works can lawfully start.
Why are more higher-risk building applications being submitted now? BSR data shows intake rose sharply from June to September 2026, which the regulator links to developers acting before the Building Safety Levy took effect on 1 October 2026.
What should I do if I receive a party wall notice linked to a nearby HRB project? Respond within the statutory timeframe, consider appointing your own surveyor, and request a schedule of condition before works begin to protect your position.
Are London approval rates different from the rest of the country? Yes. London’s new HRB approval rate was 97% against a 96% national figure, with a 22-week median determination versus 23 weeks nationally, though complex London cases run to a 35-week median.
Conclusion
The October 2026 BSR figures confirm that Gateway 2 decision-making has genuinely sped up, with London leading much of that activity. But faster building control does not shorten the separate obligations owners and developers carry under the Party Wall etc. Act 1996. Anyone involved in a higher-risk building project, or living next to one, should treat party wall notices, awards and schedules of condition as a parallel track to run alongside Gateway 2, not a step to defer until approval is in hand. Early notice service, prompt award agreement, and realistic programme contingency remain the most reliable ways to avoid delay and dispute as London’s building control pipeline continues to move at pace.
