Higher-Risk Building Gateways Explained
The Building Safety Act did not just change who oversees higher-risk buildings; it changed how those buildings get built. New control points — commonly called gateways — sit across the design and construction process, and a higher-risk building has to satisfy building safety requirements at each before it can proceed. They are, in effect, hard stops for safety. Fire alarm engineers work within this process rather than owning it, but understanding the gateways helps make sense of the environment on higher-risk building projects. This guide gives an orientation.
The central point is that higher-risk building projects must pass through gateway control points at key stages, satisfying building safety requirements before proceeding — a regime the fire alarm forms part of, though the duties rest with the construction dutyholders.
Who this is for
This is for competent fire alarm engineers working on higher-risk building projects. The experience level assumed is competent engineer. Use this as orientation; the gateways are duties of the dutyholders in the design and construction process, and the authoritative sources are the Building Safety Act, its regulations and the Building Safety Regulator's guidance. The fire alarm follows BS 5839-1.
What the gateways are
Under the Building Safety Act regime, the design and construction of higher-risk buildings pass through a set of control points, commonly called gateways, at which the building must satisfy building safety requirements before proceeding — broadly at the planning stage, before construction begins, and before occupation. Each gateway is a point where safety has to be addressed and demonstrated, not assumed, before the project moves on. The gateways are overseen within the regime led by the Building Safety Regulator. The authoritative source is the Act, the regulations and the Regulator's guidance, which should be consulted directly for the detail. For an engineer, the recognition to take away is that higher-risk projects now have formal safety checkpoints built into their progress.
Why they were introduced
The gateways exist to strengthen oversight through the life of a higher-risk building project. They were introduced to ensure that building safety is properly considered and demonstrated at key stages — design, construction and before occupation — rather than left to be discovered late or assumed. The intent is to prevent unsafe buildings progressing without the necessary checks, a direct response to failings the wider reforms sought to address. The precise gateway requirements and stages are set out in the Act, the regulations and the Building Safety Regulator's guidance, which should be consulted directly rather than relying on a summary. The principle behind them is simple: safety is checked before the project is allowed to move forward.
How they relate to the fire alarm
For fire alarm work, the gateways are context more than a direct technical change. They concern the overall design, construction and safety approval of higher-risk buildings rather than fire alarm design specifically, so their direct effect on how a fire alarm is designed is limited. But the fire alarm is part of the building's fire safety that must be right for the building to satisfy the regime, and accurate information and competent work on the fire alarm support the approvals at each stage. The fire alarm follows BS 5839-1; the gateway requirements rest with the dutyholders in the construction process. An engineer's competent work and reliable information are part of what makes the wider demonstration of safety possible.
The engineer's understanding
The practical position is to work well within the process and understand its shape. Understand that higher-risk building projects pass through gateway control points, that these are duties of the dutyholders in the design and construction process rather than the fire alarm engineer, and that the fire alarm is part of the safety that must be demonstrated. Provide competent work and accurate information to support the process, and recognise that on these projects, expectations around documentation and coordination are high. From field experience, engineers who supply clear, accurate information and do competent work make the gateway process smoother for everyone. Verify specifics against the Act and Building Safety Regulator guidance, and keep the fire alarm work to BS 5839-1.
Common points to check
For engineers, the practical points are recognising the gateway checkpoints on higher-risk projects, providing competent work and accurate information to support them, and understanding the duties rest with the construction dutyholders. Confirming competent, well-documented fire alarm work is the essential contribution.
When not to rely on this alone
When not to use this article: do not treat it as guidance for satisfying the gateways. Those are duties of the construction dutyholders under the Act, regulations and Building Safety Regulator guidance; the fire alarm follows BS 5839-1.
Relevant standards
The gateways arise under the Building Safety Act 2022 and its regulations, within the regime led by the Building Safety Regulator; the fire alarm follows BS 5839-1, a code of practice. Separate the legal duties from the recommended methods, verify specifics against the Act and guidance, and always work to current editions and guidance.
