Fire Strategy in Public and Heritage Buildings Under the Building Safety Act

The Building Safety Act has changed how fire risk is viewed in complex and regulated buildings. It is no longer just about producing a fire risk assessment. It is about demonstrating that risks are understood, managed, and governed over the life of the building.

For public buildings, heritage assets, and occupied environments, this shift is significant.

These buildings rarely fit standard guidance. They are often constrained by existing structure, listed status, public use, or phased refurbishment. Applying generic compliance solutions usually creates more risk, not less.

Fire strategy in these environments is not a box ticking exercise. It is a technical and operational problem.

The key issue under the Building Safety Act is not documentation. It is accountability.

Duty holders now need to show:

• Why decisions were made

• How risks were identified

• What trade offs were considered

• How controls are managed in operation

This applies just as much to a Victorian leisure centre or museum as it does to a high rise residential block.

In heritage and public buildings, fire strategy must balance:

• Life safety

• Building fabric and structure

• Operational reality

• Ongoing occupation

For example, introducing modern fire compartmentation or suppression systems is often structurally or culturally unacceptable. But doing nothing is not defensible either.

The solution is not perfect compliance. It is proportionate risk engineering.

This is where performance based fire strategy becomes critical. Instead of forcing the building into modern standards, the strategy must explain how equivalent or improved safety is achieved through layout, management, detection, evacuation strategy, staffing, and control of ignition sources.

Under the Building Safety Act, this approach must now be:

• Evidenced

• Justified

• Governed

• Reviewable

Fire strategy is no longer a report. It is part of the building safety case.

For duty holders, asset owners, and public bodies, the real challenge is not producing more documents. It is understanding the building as a system and managing risk over time.

In complex and listed buildings, the safest outcome is rarely the most theoretical one. It is the one that works in real life, with real people, in real operational conditions.

That is what modern fire strategy now means.
