Understanding the difference between a fire risk assessment and a fire strategy is crucial for managers, landlords, developers, and Responsible Persons in the UK. Though both documents relate to fire safety, they serve very different purposes, apply at different stages of a building’s life cycle, and are governed by different legal frameworks.
Quick Answer
A fire strategy explains how a building is designed to achieve fire safety. A fire risk assessment checks whether fire risks are being properly managed in an occupied building. The strategy is mainly about design intent; the fire risk assessment is mainly about current risk, management and compliance in use.
What Is the Main Difference?
The main difference is that a fire strategy is a design-stage document prepared to demonstrate compliance with Building Regulations, whereas a fire risk assessment is a legal requirement for managing fire safety in an occupied building.
A fire strategy focuses on how the building is designed to resist and control fire. A fire risk assessment focuses on how the building is used and whether people are adequately protected.
What Is a Fire Risk Assessment?
A fire risk assessment (FRA) is a legally required evaluation of fire hazards, the likelihood of fire, and the adequacy of existing fire safety measures in an occupied building. The purpose is to identify and manage fire risk in the building as it is used day-to-day.
Under the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must carry out a suitable and sufficient fire risk assessment for most non-domestic properties and the common parts of residential buildings.
A fire risk assessment typically focuses on:
- Identifying fire hazards
- Assessing people at risk
- Evaluating existing safety measures
- Recommending corrective actions
- Recording significant findings and actions required
You must review and update a fire risk assessment regularly, especially after changes in layout, occupancy, or use.
What Is a Fire Strategy?
A fire strategy is a technical and design-focused document that defines how a building will achieve compliance with fire safety standards at the planning and construction stage. It sets out the fire safety principles that inform design decisions, passive fire protection measures, means of escape, and other engineered solutions.
In England, fire strategies are commonly developed to demonstrate compliance with the Building Regulations, particularly Approved Document B (Fire Safety), and to satisfy Building Control requirements.
A fire strategy is usually required:
- During building design (pre-construction)
- For major refurbishments or change of use
- When planning approval or Building Regulations compliance is needed
It is typically produced by fire engineers or specialist fire safety consultants and forms part of formal submissions to Building Control to demonstrate compliance with the Building Regulations.
Key elements often covered in a fire strategy include:
- Means of escape and evacuation strategy
- Compartmentation and fire resisting structures
- Fire detection, alarm, and suppression systems
- Fire service access
- Passive and active fire safety systems
A fire strategy may be updated as a “living document” if significant changes occur during design or after construction.
Fire Risk Assessment vs Fire Strategy: Quick Comparison
| Question | Fire Risk Assessment | Fire Strategy |
|---|---|---|
| What does it do? | Reviews current fire hazards, people at risk, precautions and management arrangements. | Explains the fire safety design approach and how the building should work in fire. |
| When is it used? | During occupation and ongoing fire safety management. | During design, refurbishment, change of use, handover or when design information is missing. |
| Who needs it? | Responsible persons, landlords, employers, managing agents and duty holders. | Clients, design teams, building owners, developers, building control and responsible persons. |
| What is the output? | Risk findings, significant findings, action plan and review requirements. | Fire safety design assumptions, fire protection measures and strategy drawings or report information. |
Not Sure Which Document You Need?
Fire Risk Assessment Network can help you understand whether you need a fire risk assessment, fire strategy report, retrospective fire strategy or wider fire safety consultancy support.
Design Stage vs Occupation Stage
A fire strategy is primarily concerned with the design and construction phase of a building’s life cycle. It explains how the building has been designed to achieve fire safety compliance.
A fire risk assessment applies once the building is occupied and in use. It evaluates whether the building continues to provide adequate protection for the people inside it.
Understanding this distinction helps clarify why both documents may be required at different stages.
How Fire Risk Assessments Link to Fire Strategy
A fire strategy establishes the fire safety design principles of a building. A fire risk assessment evaluates whether those principles are being maintained in practice.
In simple terms:
- The fire strategy explains how the building was designed to achieve fire safety compliance.
- The fire risk assessment checks whether the building is operating in line with that design.
For example:
- If a fire strategy specifies protected stairwells, the fire risk assessment checks they are not compromised.
- If the strategy relies on compartmentation, the fire risk assessment verifies fire doors and fire stopping remain effective.
- If evacuation strategy assumes simultaneous evacuation, the fire risk assessment ensures procedures support this.
In this way, the fire risk assessment becomes the operational expression of the fire strategy.
Why Understanding the Difference Matters
Confusing the two can lead to non-compliance, wasted expenditure, or unsafe conditions:
- Relying on a fire strategy alone will not fulfil legal requirements for occupied buildings.
- Treating a fire risk assessment as a design compliance document can leave structural and engineered elements without proper analysis.
Knowing which document is required — and when — ensures compliance, safety, and cost-effective fire risk management.
Common Misunderstandings
Some building owners assume that having a fire strategy removes the need for a fire risk assessment. This is incorrect. Once a building is occupied, the legal duty under the Fire Safety Order applies regardless of whether a fire strategy exists.
Similarly, a fire risk assessment cannot replace a fire strategy during design or building control approval, as it does not assess structural compliance with Building Regulations.
Who Is Responsible?
The Responsible Person under the Fire Safety Order must ensure that a suitable and sufficient fire risk assessment is carried out. In contrast, the developer, architect, or building owner generally commissions the fire strategy as part of design and planning approvals.
When Might You Need Both?
You may need both documents where the building is complex, has been altered, has unclear fire safety design information or where the fire risk assessment identifies questions about escape routes, compartmentation, fire doors, external walls, smoke control or evacuation strategy.
For example, a block of flats may need a fire risk assessment to review the common parts and management arrangements, while a retrospective fire strategy may be needed if the original design intent is missing or no longer clear.

Professional Support for Both Documents
Understanding the difference between a fire risk assessment and a fire strategy is essential — but ensuring they align correctly is equally important.
In practice, we often see buildings where the original fire strategy has not been properly reflected in the ongoing fire risk assessment, or where design intent has been lost over time. This can create compliance gaps.
At Fire Risk Assessment Network, we support clients with fire risk assessments while also interpreting and reviewing existing fire strategies to ensure that operational fire safety management reflects the building’s original design principles.
Conclusion
A fire risk assessment and a fire strategy are both vital components of fire safety management in the UK — but they serve very different purposes:
- A fire strategy sets the fire safety direction during design and construction.
- A fire risk assessment ensures that the building remains safe in everyday use.
For many buildings, particularly complex developments or multi-occupancy premises, both documents are required at different stages of the building’s life cycle. Knowing the difference helps you comply with legislation, manage risk, and protect people and property.
At Fire Risk Assessment Network, we can help you understand which documents you need and provide expert support in both risk assessment and strategy interpretation.
Frequently Asked Questions
Is a fire strategy the same as a fire risk assessment?
No. A fire strategy explains the building’s fire safety design approach, while a fire risk assessment reviews current fire hazards, people at risk, precautions and management arrangements.
Do I need a fire risk assessment if I already have a fire strategy?
Yes, in most occupied premises. A fire strategy does not replace the responsible person’s duty to ensure a suitable and sufficient fire risk assessment is carried out and kept under review.
Can a fire risk assessment identify the need for a fire strategy?
Yes. If the assessment identifies uncertainty about compartmentation, evacuation strategy, fire doors, smoke control or building design assumptions, a fire strategy or retrospective fire strategy may be recommended.
Which document is needed for a new building?
A new building will usually need fire strategy input during design and approval. Once occupied, it will also need suitable fire risk assessment and ongoing fire safety management.
Can Fire Risk Assessment Network help with both?
Yes. Fire Risk Assessment Network can help arrange fire risk assessments, fire strategy report support, retrospective fire strategies and related fire safety consultancy services.
