A fire risk assessment versus strategy discussion often starts when a client is asked for a document they do not hold, or when an assessment identifies uncertainty around the building’s original fire design. The two documents are related, but they perform different functions. Treating a fire strategy as a substitute for a suitable and sufficient fire risk assessment, or expecting an assessment to recreate missing design information without further investigation, can leave significant gaps in compliance and risk control.

For UK dutyholders, the distinction matters because fire safety decisions must be evidence-led, proportionate and capable of standing up to scrutiny from enforcing authorities, insurers, residents, employees, clients and auditors. This is particularly relevant in complex premises, occupied buildings undergoing refurbishment, higher-risk residential buildings, healthcare settings, education estates, industrial sites and mixed-use developments.

Fire risk assessment versus strategy: the core difference

A fire risk assessment is an operational assessment of the risk from fire in an occupied premises. It considers ignition sources, combustible materials, people at risk, existing preventive and protective measures, management arrangements, emergency procedures and the actions required to reduce risk so far as is reasonably practicable.

In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 requires the Responsible Person to make a suitable and sufficient assessment of fire risks and keep relevant findings recorded where five or more employees are employed, where a licence applies, or where an alterations notice is in force. In practice, clear written records are expected across most managed premises because they demonstrate how decisions have been reached and actions controlled.

A fire strategy is a technical document that explains how a building is intended to achieve fire safety. It normally sets out the design assumptions and measures that support life safety and, where relevant, property protection and business continuity. These measures may include compartmentation, travel distances, escape capacity, alarm and detection systems, smoke control, evacuation lifts, firefighting shafts, external wall construction, fire service access and the management assumptions on which the design relies.

Put simply, the strategy establishes the intended fire safety approach. The assessment examines whether the premises, its use and its management continue to support that approach.

What a fire risk assessment should establish

A competent fire risk assessment is not merely a checklist of extinguishers, signage and alarm test records. It must consider the premises in use, including changes that may have occurred since construction or the previous assessment.

The assessor will normally examine the likelihood of fire, the people who could be affected, the adequacy of escape routes, the condition and management of passive fire protection, warning and detection arrangements, emergency lighting, fire doors, housekeeping, maintenance records and staff competence. The assessment should identify significant findings, prioritise remedial actions and specify who should complete them and by when.

For a construction project, the findings may need to align with the project fire plan, site induction arrangements, hot works controls, temporary electrics, combustible storage, emergency access and the requirements of CDM 2015. For a facilities team, the emphasis may be on planned preventive maintenance, changes of use, tenant controls, contractor management and the evidence required for audit readiness.

An assessment is also time-sensitive. It should be reviewed regularly and whenever material change occurs, such as alterations to layout, occupancy, processes, fire systems, escape arrangements or the needs of building users. A once-compliant assessment can become unreliable if the building and its management have changed around it.

What a fire strategy should contain

A fire strategy is usually prepared during design, often by a suitably competent fire engineer or specialist. It translates fire safety objectives into a coordinated design basis. It can be a concise document for a straightforward building, but larger or unusual schemes may require detailed analysis, drawings, calculations and consultation with Building Control and other stakeholders.

A well-developed strategy should describe the building, its occupancy profile and evacuation philosophy. It should make clear whether the building relies on simultaneous evacuation, phased evacuation, stay put, defend in place or a different managed approach. It should also identify the fire-resisting construction and systems necessary to make that approach viable.

For example, a residential building operating a stay-put policy depends on reliable compartmentation between flats, protected common parts and appropriate information for residents. A strategy may define the required fire resistance of walls and floors, flat entrance doors, smoke ventilation provision and firefighting access. The fire risk assessment then considers whether those features remain in place, are maintained, and are supported by suitable resident communication and management arrangements.

The strategy is therefore not only a design-stage document. It can remain a critical reference document throughout occupation, alteration, refurbishment and change of use.

Design intent is not proof of current performance

An original fire strategy may be technically sound yet no longer reflect the building as it stands. Later fit-outs, service penetrations, unrecorded alterations, door replacements and changes to occupancy can undermine the measures assumed by the designer.

Conversely, a fire risk assessment may identify concerns that cannot be resolved from visual inspection alone. If the assessor cannot verify the construction or intended performance of a compartment wall, fire stopping, cavity barrier or smoke-control system, further intrusive investigation, fire-door inspection or compartmentation survey may be required. The right response depends on the risk, available evidence and consequences of failure.

When both documents are needed

Many straightforward, low-complexity premises may have a fire risk assessment without a formal standalone fire strategy. That does not remove the need to understand the building’s fire precautions; it simply reflects that the building’s design and use may be relatively conventional.

A strategy becomes especially valuable where the premises are complex, subject to phased construction, materially altered, or reliant on engineered fire safety measures. It is commonly required for new-build design and substantial refurbishment, and it may be requested during due diligence, insurance review, acquisition, lease negotiations or enforcement engagement.

Both documents should be available and reconciled where a building has one or more of the following characteristics:

• a higher-risk residential building or a complex residential arrangement;
• smoke-control systems, evacuation lifts, sprinklers or other engineered measures;
• a phased or managed evacuation plan;
• significant compartmentation requirements or complex fire-stopping interfaces;
• unusual occupancy, high numbers of vulnerable persons or 24-hour occupation; or
• major change of use, extension, refurbishment or retrospective regularisation work.

For external wall issues in England, a FRAEW is a distinct, specific assessment process and should not be confused with either a general fire risk assessment or a building fire strategy. Its scope, competence requirements and methodology need to be defined carefully, particularly where PAS 9980 principles are relevant.

Common compliance failures

The most frequent problem is document mismatch. A strategy may state that a corridor is protected, but later works may have introduced unsealed service penetrations. An assessment may recommend maintaining a fire door, while the door itself has been replaced with an unsuitable product or its certification evidence is unavailable. A premises may rely on a stay-put approach while its management plan tells occupants to evacuate on alarm.

Another issue is relying on generic assessments that do not address the premises’ actual risk profile. A warehouse with lithium-ion battery charging, hot works and high-piled combustible storage requires a different level of analysis from a small office. DSEAR considerations may also arise where dangerous substances, flammable liquids, gases or combustible dusts are present.

There is also a commercial consequence. Missing or contradictory fire safety information can delay handover, disrupt planned works, increase remedial costs and make it difficult for responsible persons to demonstrate effective control. Clear records reduce uncertainty before a project, audit or incident exposes it.

Turning documents into operational controls

The value of a fire strategy and assessment lies in how they inform action. The Responsible Person, facilities manager, building owner, principal contractor and managing agent may each hold parts of the control framework, so responsibilities need to be explicit.

Where a strategy exists, its assumptions should be translated into a practical compliance schedule. This may include inspection and testing frequencies, fire-door and compartmentation inspection programmes, impairment procedures for alarm or smoke-control systems, tenant fit-out controls, permit-to-work requirements and escalation routes for defects. Actions raised through the fire risk assessment should then be prioritised according to risk, assigned to competent persons and tracked to closure.

For refurbishment or intrusive maintenance, contractors should receive the relevant fire safety information before work starts. RAMS, permit systems and site controls must protect existing compartment lines, temporary escape routes and critical fire systems. Where works affect the building’s fire precautions, the strategy may need formal review rather than an informal note on a project file.

Evolution Safety Solutions can support this process through fire risk assessments, fire-door and compartmentation inspections, compliance audits, training and clearly defined remedial action plans. The objective is not simply to produce reports, but to give dutyholders reliable evidence and workable controls.

Choosing the right starting point

If the immediate question is whether people can safely occupy and evacuate a premises, begin with a competent fire risk assessment. If the uncertainty concerns how the building was designed to control fire, particularly following alteration or where engineered measures are present, establish whether a current fire strategy exists and whether it remains valid.

Where records are incomplete, avoid assumptions. Gather available drawings, Building Regulations information, system commissioning records, maintenance histories and previous assessments, then define the surveys or specialist input needed to close the evidence gap. A clear understanding of intended performance is the foundation for managing actual fire risk.
