The Regulatory Gateway Regime
Three gateways.
Each one has the power
to stop your project.
The gateway regime is the spine of the Building Safety Act. At each gateway,
the Building Safety Regulator reviews whether a higher-risk building project
may proceed. The requirements are mandatory. The consequences of failing to
meet them are programme delay, enforcement action, and personal liability for
named duty holders.
Regulatory Note
The three-gateway regime applies to higher-risk buildings as defined under the Building Safety Act 2022 and the Higher-Risk Buildings (Descriptions and Supplementary Provisions) Regulations 2023. Certain building types — including hospitals and schools — are subject to modified gateway requirements and Gateway 3 does not apply to all higher-risk buildings. Duty holders should verify the specific requirements applicable to their building type and use class. This page provides a general overview only and does not constitute legal or regulatory advice.

Gateway 1 — Planning
No planning consent
without a fire statement.
Required with every planning application for an HRB
Gateway 1 is the first regulatory intervention — and the most consistently underestimated.
A fire statement must accompany every planning application for a higher-risk building.
The planning authority must consult the HSE. The HSE can object. An HSE objection
means no planning permission. That is not a theoretical risk — it has happened.
The fire statement must demonstrate that fire safety has shaped the design from the outset.
It is an evidence commitment, not a narrative document. When the design changes after
consent — and it always does — that commitment becomes an expanding liability.
Most projects have no mechanism to track the gap.
STRAND detects every change to fire safety elements from the first scan. Compartmentation,
escape routes, fire systems — all monitored. The gap between the Gateway 1 statement
and the current design is visible in real time, not discovered at Gateway 2.
What Gateway 1 Requires
- Fire statement submitted with planning application
- Demonstration that fire safety has informed the design
- Mandatory HSE consultation on HRB applications
- Evidence of fire engineer involvement at concept stage
- Escape strategy, fire service access, compartmentation principles
The Hidden Risk
A Gateway 1 fire statement that no longer reflects the current design creates
an evidence gap that must be closed before Gateway 2. The longer it goes
undetected, the harder and more expensive the close. STRAND makes it visible from day one.

Fire intelligence from the first drawing
STRAND's fire engine reads fire safety elements from every drawing and builds
a live fire intelligence model. Every compartment boundary, every escape
route, every fire door — registered, tracked, and flagged the moment it changes.
- Compartmentation detection and register
- Escape route configuration tracking
- Fire door schedule and certification monitoring
- Fire strategy change detection via geometry comparison
- Golden thread logging of all fire-relevant decisions
- Automatic RFI escalation for fire specification gaps

Gateway 2 — Pre-Construction
No construction
without BSR approval.
Required before a spade goes in the ground
Gateway 2 is the hardest gate in the regime. The Building Safety Regulator
reviews the complete design and documentation package before construction may begin.
No exceptions. No discretion. No workarounds.
The BSR targets 8 weeks to determine a valid application — but that clock
does not start until the application passes validation. Incomplete applications
are rejected before the determination period even begins. Every week of unnecessary
delay costs money. Projects have been derailed by incomplete submissions that were
entirely preventable.
Fourteen mandatory checklist items. Four prescribed documents. Competence declarations
against named PAS standards. A complete drawing set. Every item must be present.
Every document must be substantive. A stub document is not compliance —
and the BSR validation team knows the difference.
The 14 Mandatory Checklist Items
- Project name and applicant details (A001)
- Building details — storeys, height, units, use (A002)
- Description of proposed work — project brief (A003)
- Drawing set completeness (A004)
- Drainage strategy where applicable (A005)
- Partial completion strategy where applicable (A006)
- Principal Designer competence declaration — PAS 8671 (B001)
- Principal Contractor competence declaration — PAS 8672 (B002)
- Building Regulations Compliance Statement (B003)
- Fire and Emergency File (B004)
- Construction Control Plan (B005)
- Change Control Plan (B006)
- Mandatory Occurrence Reporting Plan (B007)
- Client, PD, PC details — planning reference — programme (C001)
The Cost of Getting It Wrong
A rejected Gateway 2 application does not pause the programme — it stops it.
Resubmission takes time. Revalidation takes time. The determination period
does not run during either. Projects have lost months to incomplete applications
that STRAND would have caught before submission.
STRAND at Gateway 2
Complete audit. One-button pack compilation.
STRAND audits all 14 checklist items continuously. Every missing or partial item
raises an emergency RFI immediately. When the pack is ready, one button compiles
the complete submission — documents, drawings, declarations — ready for the BSR portal.
- 14-item checklist audit — Present / Partial / Missing
- Building Regulations Compliance Statement (BRCS)
- Construction Control Plan (CCP)
- Change Control Plan (ChCP) with live change log
- Mandatory Occurrence Reporting Plan (MORP)
- Competence declaration tracking — PAS 8671/8672/8673/8674
- BSR submission pack — compiled in one operation
- Emergency RFIs for every missing or partial item

Gateway 3 — Completion
No occupation without
the completion certificate.
Applies to most HRBs — verify requirements for your building type
For higher-risk buildings within scope of Gateway 3, occupation cannot begin
without a completion certificate from the Building Safety Regulator. The BSR
reviews the as-built position and confirms it matches Gateway 2 approval.
A building that is structurally complete but fails this review cannot be occupied.
Not for a single day.
This is where projects that cut corners collapse. Every change made during
construction must be accounted for. Every departure from the Gateway 2 approved
design must have been notified — and where required, approved by the BSR —
before the work was carried out. Retrospective justification is not a remedy.
A building generating no revenue, with finance costs still running, and occupation
withheld because the evidence base is incomplete — that is the Gateway 3 failure mode.
The liability rests with the duty holders. Individually. Personally.
With no corporate shield available under the Building Safety Act.
What Gateway 3 Requires
- Completion certificate application to the BSR
- As-built golden thread — complete, structured, and digital
- Evidence that all Gateway 2 approved elements are as built
- Full change control record — every controlled change evidenced
- All mandatory occurrence reports made and resolved
- Competence declarations — current at the point of completion
- Fire and Emergency File — updated to as-built position
- Handover package for the Accountable Person
The Point of No Return
Gateway 3 is not a completion task. It is the result of everything that was
or was not done from Gateway 1 onwards. Projects that have not maintained
their golden thread continuously cannot reconstruct it at the end.
The evidence either exists or it does not.
STRAND at Gateway 3
The evidence exists. It has been building since day one.
STRAND maintains the golden thread throughout construction. Every drawing revision,
every change control entry, every RFI, every competence update is logged immutably.
At Gateway 3, the evidence is not assembled — it is retrieved.
- Immutable golden thread — complete construction record
- As-built drawing register — full revision history
- Change control log — every controlled change evidenced
- Occurrence register — all reportable events recorded
- Competence declaration currency tracking
- Completion and handover pack compilation
- Fire and Emergency File — as-built version
