Fire Strategy for buildings: A comprehensive guide to Fire Safety Planning

Why every building needs a Fire Strategy

A Fire Strategy is a comprehensive document that explains exactly how a building has been designed to meet fire safety requirements and protect occupants in the event of a fire. It sets out the building’s approach to means of escape, compartmentation, fire detection and alarm systems, smoke control, firefighting access, and ongoing fire safety management in one coordinated plan.

Fire Strategy documents are commonly required for new developments, major refurbishments, changes of use, and higher-risk or complex buildings. They help demonstrate compliance with Building Regulations (for example, Approved Document B in the UK) and provide a clear framework for maintaining fire safety throughout the life of the building. In this sense, a well-prepared fire strategy plan is often essential for gaining building control approval and satisfying wider building regulations requirements.

For building owners, developers and duty holders, a Fire Strategy is one of the most important documents within a building’s fire safety portfolio. It underpins key design decisions, guides contractors during construction, and supports future Fire Risk Assessments and day-to-day management of the premises.

The rest of this guide explains what a Fire Strategy is in more detail, when it’s required, what it should include, and how to ensure yours is compliant and fit for purpose.

What is a Fire Strategy?

A Fire Strategy is a holistic Fire Safety Plan for a building. It is not just about alarms, extinguishers or sprinklers – it brings together every aspect of fire safety design, construction and ongoing management into one coordinated approach.

In simple terms, a Fire Strategy:

• Explains how the building has been designed to meet fire safety requirements in the building regulations
• Guides architects on compliant layouts, escape routes, compartmentation and systems
• Informs contractors what needs to be installed, to what standard, and how systems should interact
• Supports building owners and managers in understanding the limits of the building and how to safely occupy and manage it

Key focus areas include:

• Life safety – protecting occupants and ensuring safe escape or stay-put strategies as appropriate
• Property protection – limiting damage to the building and contents, and supporting business continuity
• Compliance with regulations – demonstrating that the design meets Approved Document B or other relevant guidance (e.g. BS 9991, BS 9999, HTM guidance for hospitals)

A good Fire Strategy Document ties all of this together in a clear, evidence-based way.

Why is a Fire Strategy important?

A robust Fire Strategy is critical for several reasons:

Legal compliance

A Fire Strategy is typically required to demonstrate compliance with building regulations (in England, this is often via Approved Document B, Volume 1 or Volume 2, depending on the building type). For many projects, building control will not sign off the works without a suitable Fire Strategy in place.

Protecting occupants and firefighters

The strategy directly impacts:

• How people are warned of a fire
• How quickly and safely they can escape
• How effectively the building limits fire and smoke spread
• How safely the fire and rescue service can access and fight a fire

A poor or incomplete strategy can create hidden vulnerabilities that only become apparent when it’s too late.

Supporting the design and construction team

The fire strategy underpins decisions made by:

• Architects – on layout, stair cores, lobbies, escape routes, compartmentation, and façade design
• Engineers and contractors – on systems design (alarms, smoke control, suppression, etc.)
• Developers and building owners – on intended use, occupancy levels, and long-term management

Without a clear strategy, contractors may “press on” with construction and only later discover that key elements don’t comply. This can lead to prohibition notices, expensive rework, or even partial demolition if the building cannot be made compliant in its as-built form.

4. When is a Fire Strategy required?

A Fire Strategy Plan is typically required whenever a building is going through design or significant change that falls under building control. Common scenarios include:

• New builds: Almost all new buildings will require a fire strategy to secure building control approval.

• Major refurbishments and alterations: For example:

• • • Introducing new entrances or exits
    • Changing internal layouts
    • Installing or altering cladding or façade systems

• • Any material change to the structure or layout that affects fire safety should trigger a review/update of the Fire Strategy.

• Change of use

• • Converting offices into residential flats, turning warehouses into leisure spaces, etc.
  • A change in use typically brings a new set of fire safety rules and expectations, particularly for residential and higher-risk occupancies.

• Complex or high-risk buildings

• • High-rise buildings (over 18m)
  • Complex mixed-use schemes
  • Buildings housing vulnerable occupants (e.g. care homes, hospitals)
  • In such cases, regulators and the Building Safety Regulator will often expect a detailed, robust Fire Strategy to justify that risk has been properly managed.

It’s important to note:

• Not every existing building will necessarily have, or legally require, a full Fire Strategy Document.
• Once a building is occupied, a Fire Risk Assessment is mandatory and becomes the key legal requirement.
• However, for complex or higher-risk premises, a current Fire Strategy provides essential context and is often expected by regulators and insurers.

5. Key components of a Fire Strategy document

Although every building is unique, a Fire Strategy will usually follow the structure of Approved Document B’s five key areas (B1–B5) and can be broken down into the following components for clarity.

5.1 Means of escape

This section covers how people will safely evacuate the building (or, in some cases, safely remain in place under a stay-put strategy) and typically includes:

• Escape routes and exits

• • Number, width and arrangement of staircases
  • Horizontal and vertical escape routes
  • Final exits and discharge to a place of safety

• Travel distances

• • Maximum permitted travel distances to a place of relative safety (e.g. a protected stair)
  • Justification where distances are extended, including any compensatory measures

• Emergency lighting and signage

• • Locations and standards of emergency lighting
  • Fire exit signs and directional signage to guide occupants

5.2 Fire detection and alarm systems

The strategy will define:

• Type of fire alarm system (e.g. category L1, L2, L3, etc. for life safety)
• Coverage requirements

• • Whether the whole building needs automatic detection or only specific areas
  • Differentiation between communal and individual dwelling systems in residential schemes (e.g. blocks of flats)

• Cause-and-effect

• • How alarms interact with systems such as smoke control, door release mechanisms, evacuation lifts, etc.

5.3 Compartmentation

Compartmentation is a critical part of controlling internal fire spread and is often misunderstood as being the same as a Fire Strategy – it isn’t. It is one component of the wider strategy.

The compartmentation section will typically:

• Identify fire-resistant walls, floors and ceilings
• Define the required fire resistance ratings (e.g. 30, 60, 120 minutes)
• Highlight fire doors, fire-stopping requirements, and protected shafts
• Show compartment lines on plans and explain how spread of fire and smoke between areas is restricted

A compartmentation plan may be produced alongside or as a subset of the Fire Strategy to visually map these boundaries and requirements.

5.4 Fire suppression systems

Where applicable, the Fire Strategy will detail:

• Sprinkler systems

• • Type, coverage and standards followed

• Other suppression methods

• • e.g. gaseous systems, water mist, or local suppression in high-risk areas (plant rooms, commercial kitchens, etc.)

• How these systems integrate with detection, alarms and smoke control.

5.5 Smoke control

Controlling smoke is vital for both life safety and firefighting operations. This section may cover:

• Natural and mechanical smoke ventilation systems
• Smoke shafts, vents, and automatic opening vents (AOVs)
• How smoke control systems are triggered (e.g. via the fire detection system)
• Design principles and applicable standards for the chosen strategy

5.6 Firefighting access

To allow the Fire and Rescue Service to intervene effectively, the strategy sets out:

• Access routes for fire appliances

• • Appliance access around the building
  • Turning circles and hardstanding requirements

• Firefighting shafts and lifts where required
• Locations of dry risers, wet risers and hydrants
• Provisions for water supplies and operational access internally

5.7 Management and maintenance

Fire safety does not end at handover. The strategy should also address:

• Ongoing management responsibilities: Who is responsible for maintaining systems and procedures
• The relationship with the Fire Risk Assessment: How the risk assessment should reference and align with the fire strategy
• Requirements for future reviews and updates if occupancy, layout, or use changes
• Expectations for competent contractors (e.g. third-party accredited installers for alarms, fire doors, and fire-stopping)

6. Fire Strategy and building regulations

In the UK, a Fire Strategy is closely tied to building regulations compliance. For most buildings, that will mean demonstrating alignment with:

• Approved Document B (Volume 1 – dwelling houses / Volume 2 – buildings other than dwelling houses), and/or
• Alternative guidance such as BS 9991, BS 9999, or sector-specific documents (e.g. HTM guidance for healthcare)

Key points:

• A Fire Strategy document supports planning and building control approvals by clearly setting out how the design meets the relevant guidance or justified deviations from it.
• For more complex or innovative designs, performance-based approaches (e.g. using BS 9999, or fire engineering principles) may be used instead of or in addition to strict compliance with Approved Document B.
• You cannot cherry-pick the most favourable clauses from different documents without proper justification. If a fire engineer chooses BS 9999 for specific benefits, they must apply it appropriately and consistently across the strategy, with clear reasoning.

A well-prepared Fire Strategy gives regulators confidence that the building’s fire safety design has been carefully thought through and professionally justified.

7. Who prepares a Fire Strategy?

A Fire Strategy should always be prepared by a qualified and competent Fire Engineer or Fire Safety Consultant. Typically, this means:

• Degree-level qualifications in fire engineering or related discipline
• Extensive experience in applying building regulations and fire safety standards
• Often Chartered Engineer status or equivalent professional recognition

At Pyro Fire, we work with Chartered Fire Engineers and experienced fire safety professionals who:

• Develop Fire Strategies for a wide range of building types and complexities
• Understand how to balance regulatory compliance, design intent and practicality
• Can liaise effectively with architects, contractors, and regulators to see a project through from early concept to completion

Given the high stakes and the elevated professional indemnity insurance environment for fire engineering, a “cheap” Fire Strategy is often a red flag. This work is detailed, high-responsibility, and must be done properly.

8. Common mistakes in Fire Strategy Planning

Some of the recurring issues we see in practice include:

• Treating it as a tick-box exercise

• • Minimal, generic reports that don’t reflect the actual building or design
  • Missing key details such as floor plans, fire resistance ratings or clear evacuation strategies

• Poor coordination with the design team

• • Fire strategies produced too late, after construction has already progressed
  • Requirements not properly communicated to architects and contractors
  • Conflicts between the strategy and the as-built layout or systems

• Cherry-picking from multiple guidance documents

• • Selecting the “best” numbers or allowances from different codes without applying them coherently
  • Referencing outdated or incorrect British Standards

• Ignoring ongoing management

• • No clear link between the Fire Strategy and the building’s future Fire Risk Assessment
  • No guidance on management responsibilities, system maintenance or competency of contractors

These issues can lead to significant non-conformities, delays and remedial costs once a Fire Risk Assessor or regulator reviews the building.

9. How to ensure your Fire Strategy meets regulations

To give your project the best chance of smooth approval and long-term safety, consider the following best practice steps:

Engage experts early

• Involve a competent Fire Engineer at the concept and early design stages.
• Ensure they have a proven track record with similar building types – ask for:

• • CVs and evidence of competence
  • Case studies
  • References from previous clients

Maintain accurate documentation

• Ensure drawings and specifications are up-to-date and aligned with the Fire Strategy.
• Keep clear records of:

• • Design changes
  • Deviations from standard guidance and the justification for them
  • Approvals and feedback from building control or the Fire and Rescue Service

Coordinate with Architects and Contractors

• Make sure key stakeholders understand and follow the Fire Strategy.
• Include its requirements in:

• • Design team meetings
  • Contractor briefings
  • Tender and appointment documents

Review and uupdate as the building evolves

• If there are major changes in design, layout or use, the Fire Strategy should be reviewed and updated.
• Once the building is occupied, ensure the Fire Risk Assessment references and respects the original design principles – or, where change is needed, that it is done under professional guidance.

10. Conclusion

A well-designed Fire Strategy document is far more than a formal requirement – it is the backbone of safe, compliant and resilient buildings. It ensures:

• Life safety for occupants and firefighters
• Protection of property and business continuity
• Compliance with building regulations and fire safety legislation

By engaging qualified Fire Engineers, coordinating with your design and construction teams, and treating the Fire Strategy as a live, technical document rather than a formality, you can significantly reduce risk and avoid costly surprises later in the project.
