The Building Safety Act – What Gateway Two Really Means for Fire Safety
The Building Safety Act has transformed the way the sector approaches risk, accountability, and regulatory oversight. Good intentions are no longer enough to provide evidence – understandably, as buildings need to meet rigorous standards to comply with the Building Safety Regulator at every stage of the process.
Gateway Two introduces significant challenges for those delivering rectification works for higher-risk buildings. This stage is far more than a procedural milestone; as without approval, construction cannot begin. Therefore, understanding what is required is quintessential to avoid delays, redesigns, and unnecessary costs.
Why fire safety sits at the heart of Gateway Two
Gateway Two is a legally mandated stage where the fire safety strategy for a project is scrutinised in detail. Responsibility lies with Accountable Persons (APs) and Principal Accountable Persons (PAPs) – those legally recognised as responsible for managing structural and fire safety risks in higher-risk buildings.
These are typically buildings either 18m or seven storeys high, with at least two residential units. APs must demonstrate how fire related risks within their areas of control have been identified, assessed, and mitigated. A clear paper trail is essential; while tasks can be delegated to specialists, the legal accountability remains with the AP throughout.
Where higher-risk projects often face delays
Fire safety cannot be resolved at the documentation stage. A successful Gateway Two submission requires:

All compiled in line with Regulation 4 of The Building (Higher-Risk Buildings Procedures) (England) Regulations.
When fire safety considerations aren’t embedded early, the result is often delayed approvals, rework, and in some cases, complete rejection.
How Miller Knight supports Gateway Two readiness
The increasing scrutiny introduced under the restructured regulatory framework has sharpened expectations for evidence and planning. For many project teams, meeting fire safety requirements has become one of the most difficult aspects of Gateway Two.
At Miller Knight, we support clients by embedding robust passive fire protection thinking into the early design process and guiding APS through their compliance responsibilities.

Miller Knight’s Gateway Two and Three expertise
Miller Knight has significant experience supporting clients through the Gateway Two process, ensuring that the required fire safety information, evidence, and documentation are properly coordinated and presented in line with Building Regulations. We work closely with project teams to help them meet the regulatory demands of this critical stage and achieve successful submissions.
Our involvement continues into Gateway Three, where we assist in demonstrating that planned fire safety measures have been delivered, verified, and recorded in accordance with the Building Safety Regulator’s expectations. This ensures a clear and compliant pathway from design intent through to completed works.
As a FIRAS accredited contractor, our approach provides clients with confidence that fire safety requirements are met consistently and robustly throughout the building’s lifecycle.
