Gateway 2 Fire Safety Information: what a coordinated submission needs to show

Gateway 2 applications for higher-risk buildings require a coordinated body of information showing how the proposed work will comply with the Building Regulations.

Recent government clarification has addressed a common point of confusion: a standalone document titled “fire safety strategy” is not currently prescribed for every Gateway 2 application. That does not reduce the importance of fire safety evidence. Instead, the focus should be on whether the application consistently demonstrates the proposed fire safety approach across the relevant information and documents.

What is required at Gateway 2?

The Building Safety Regulator (BSR) requires a package of information for a building control approval application, including drawings and plans, a building regulations compliance statement, a construction control plan, a change control plan, a competence declaration, a mandatory occurrence reporting plan and, where applicable, a fire and emergency file or fire compliance statement. The precise requirements depend on the proposed work and the type of application.

For new higher-risk buildings and Category A work to existing higher-risk buildings, the fire and emergency file is required. BSR states that this is often known as a “fire strategy” and that it should demonstrate matters including means of escape and warning, measures to inhibit fire spread, and access and facilities for the fire service.

The key issue is therefore not whether a project has produced a document with a particular title. It is whether the fire safety information submitted to BSR is complete, consistent and supported by the wider application.

A fire strategy can still be valuable

Many project teams use a fire strategy to bring the fire safety design approach together. This can remain a useful coordination document, particularly on complex projects.

The important point is that it should not sit apart from the rest of the application. Its assumptions and conclusions need to align with the plans, specifications, calculations, product information and other supporting evidence.

For example, if the fire safety information relies on a particular evacuation approach, compartmentation arrangement or smoke-control solution, the relevant drawings and technical information should reflect the same design.

The government’s September 2026 progress report confirms that work is continuing on how the current higher-risk building regime should develop in response to the Grenfell Tower Inquiry’s Recommendation 10. The position should therefore be kept under review as policy and guidance develop.

Test the interfaces, not only the documents

Submission quality is often determined at the interfaces between disciplines.

Architectural layouts affect escape routes and compartment lines. Mechanical and electrical services create penetrations and may support smoke control or firefighting systems. Structural decisions can affect fire resistance, while product selections can determine the evidence needed to demonstrate performance.

A useful Gateway 2 readiness review should therefore test these connections rather than checking documents in isolation.

BSR’s application guidance specifically asks applicants to refer to relevant drawings and plans throughout the application and direct the regulator to the relevant information.

Keep fire safety information under change control

Coordination does not stop when the Gateway 2 application is submitted.

Once an application has been approved, the documents uploaded for the application become the agreed documents. Changes to those documents are controlled changes and must be assessed and managed through the project’s change control process. BSR requires the change control log to identify affected agreed documents and explain how Building Regulations compliance will still be maintained.

This matters for fire safety because an apparently local change can affect the wider compliance case. Moving a door, changing a product or rerouting a service may alter compartmentation, escape arrangements or other fire safety assumptions.

The construction control plan also needs to explain how evidence will be collected and retained during construction, including the as-built evidence needed to support completion.

A practical pre-submission check

Before submitting a Gateway 2 application, project teams should be able to answer four questions:

1. 1Where is each relevant fire safety requirement demonstrated?
2. 2Do the drawings, specifications and narrative documents use the same assumptions?
3. 3Is supporting evidence available for the relevant products, systems and calculations?
4. 4Can future changes be assessed and traced across the submission set?
