Planning Gateway One is starting to change where fire safety risk is dealt with in high-rise development. The Building Safety Regulator has reported that fire safety objections at planning stage fell from an average of 57% in 2022 to 10% in 2025, suggesting that applicants are beginning to address critical fire safety issues earlier in the design process. The visible story is regulatory improvement. The more important construction story is that early-stage design discipline is becoming a programme control mechanism. For developers, Principal Designers, fire engineers and contractors, the planning stage is no longer just about securing consent; it is increasingly where later Gateway 2 risk is either reduced or embedded.
While falling Planning Gateway One objections may look like a planning success story, London Construction Magazine analysis shows that earlier fire safety scrutiny is shifting delivery risk upstream, forcing design teams to resolve access, evacuation, facade and fire strategy issues before they become Gateway 2 approval delays. The BSR has described the trend as evidence of stronger submissions, more consistent decision-making and earlier technical conversations. For construction teams, that matters because the same unresolved issues that once appeared late in the approval cycle can now affect land value assumptions, design freeze dates, procurement timing and contractor mobilisation.

| By the Numbers | Operational Reading |
| 57% average objection rate in 2022 | Early submissions were frequently failing to resolve planning-stage fire safety concerns. |
| 10% objection rate in 2025 | Applicants appear to be engaging with fire strategy earlier, reducing avoidable planning friction. |
| Planning Gateway One before Gateway 2 | Design risk is being tested earlier, before construction approval becomes a programme-critical blocker. |
| More consistent submissions | Better planning information can reduce later query cycles, redesign pressure and approval uncertainty. |
| Earlier regulator engagement | Technical conversations are moving closer to concept design, not waiting until construction readiness. |
Why the Objection Rate Matters
A lower Planning Gateway One objection rate suggests that applicants are no longer treating fire safety as a late technical attachment. They are being pushed to consider fire service access, evacuation strategy, external wall risk and building layout much earlier in the planning process. That shift matters because late fire strategy changes are rarely isolated design edits. They can affect core layouts, facade zones, stair design, service risers, plant locations, structural coordination and commercial floor efficiency. Once those changes land after planning, they can destabilise the entire pre-construction programme. For London projects, where high-rise sites are often constrained by tight boundaries, neighbouring assets, road access limits and dense urban interfaces, early fire safety clarity can be the difference between a controlled submission and a chain of redesign cycles.
Where Gateway 2 Risk Starts Earlier
Gateway 2 approval risk often appears to sit at the point where construction cannot lawfully start, but the weakness usually forms much earlier. Poorly resolved fire assumptions, fragmented consultant inputs and unclear evidence trails can all begin during planning and concept design. This is why Planning Gateway One is becoming more important than many project teams first assumed. It is not a substitute for Gateway 2, but it can expose whether the project is developing a coherent safety logic or simply assembling information in stages without enough technical integration. LCM has previously examined why Gateway 2 applications are delaying London high-rise projects, particularly where design information, compliance evidence and dutyholder coordination are not mature enough at submission stage.
The Design Freeze Problem
The practical friction for project teams is that earlier fire safety resolution also means earlier design commitment. Developers may welcome lower planning objections, but contractors and consultants still need enough certainty to price, sequence and coordinate the work without inheriting unresolved compliance assumptions. This is where programme tension starts. If the fire strategy is only partially resolved at planning stage, the project may still move forward commercially, but the unresolved details can reappear during Gateway 2 as amended drawings, clarifications, technical queries or design freeze delays. For contractors, the risk is not only regulatory delay. It is procurement instability. Facade packages, fire stopping interfaces, smoke control systems, dry risers, access routes, plant areas and structural penetrations all become harder to price when the fire safety logic is still moving.
Why Better Planning Submissions Do Not Remove Delivery Pressure
The fall in objections is positive, but it does not mean the approval system has become risk-free. It means one part of the system is beginning to behave more predictably, while downstream Gateway 2, remediation and construction control pressures remain exposed to submission quality and evidence coordination. The strongest projects will now be those that connect planning fire strategy, Gateway 2 evidence, Golden Thread records and contractor buildability into one traceable route. The weakest projects will continue to treat each gateway as a separate compliance exercise, creating gaps between what was approved, what was designed and what can actually be built. That issue is visible across the wider BSR system, including remediation and higher-risk building control. LCM’s previous coverage of BSR’s new Remediation Enforcement Unit showed how unresolved safety work is increasingly being treated as an enforcement and delivery problem, not just a technical approval issue.
What Developers and Contractors Should Watch
The next pressure point is whether better Planning Gateway One performance converts into cleaner Gateway 2 submissions. If early fire safety objections fall but Gateway 2 queries remain high, the system may be improving at planning presentation while still struggling with technical evidence depth. For delivery teams, the practical question is whether fire safety decisions are being recorded, coordinated and translated into buildable information early enough. That means checking not only whether the planning position is acceptable, but whether the same assumptions are visible in design responsibility matrices, procurement scopes, fire strategy evidence and construction sequencing.
Projects that treat Planning Gateway One as an early warning system are likely to gain more control over approval risk. Projects that treat it as a planning hurdle may still discover the real cost later, when redesign, evidence gaps and package coordination begin affecting mobilisation. The full contractor implications, sequencing risks and mitigation strategies are included in today’s London Construction Magazine briefing.
Evidence-Based Summary
Planning Gateway One objections falling from 57% in 2022 to 10% in 2025 suggests that fire safety is being considered earlier and with greater consistency. The deeper operational shift is that planning-stage fire strategy is now influencing Gateway 2 readiness, procurement certainty and contractor mobilisation risk. As planning, regulation, design coordination and construction evidence become more connected, high-rise delivery pressure is increasingly shaped by decisions made before projects reach the main approval gateway.
