What is a Fire Risk Assessment? Legal requirements & what’s involved

A Fire Risk Assessment is a legal requirement for almost every workplace and non-domestic building in the UK. Yet many organisations still misunderstand what a proper assessment involves.

Some assume it is simply a checklist exercise or a form that needs to be completed for compliance. In reality, a professional Fire Risk Assessment is a structured and comprehensive evaluation of a building’s fire risks, safety systems, and evacuation arrangements.

Understanding what is involved – and ensuring the assessment is carried out competently – is essential for protecting people, property, and business operations.

In our latest blog, Erik, Managing Director of Pyro Fire, explains:

What is a Fire Risk Assessment?

A Fire Risk Assessment is a systematic process used to identify fire hazards within a building and evaluate the risk they pose to occupants. The goal is to determine whether existing fire safety measures are adequate and to identify actions required to reduce risk.

A professional Fire Risk Assessment typically involves:

• Inspecting the building and its layout

• Identifying potential fire hazards

• Assessing who could be at risk

• Reviewing fire detection and protection systems

• Evaluating escape routes and evacuation procedures

• Documenting findings and recommended improvements

The result is a Fire Risk Assessment report, which records significant findings and forms the basis of ongoing fire safety management.

A properly conducted assessment helps ensure that fire safety arrangements are suitable and sufficient, as required by UK legislation.

Fire Risk Assessment legal requirements in the UK

Fire safety law in England and Wales is primarily governed by the Regulatory Reform (Fire Safety) Order 2005.

This legislation applies to:

• Almost all non-domestic premises

• Workplaces and commercial buildings

• Public buildings

• Shared areas of residential buildings, such as blocks of flats

Under this legislation, the Responsible Person must:

• Carry out a Fire Risk Assessment

• Identify fire hazards and people at risk

• Implement appropriate fire safety measures

• Record significant findings

• Regularly review and update the assessment

Failure to comply with these requirements can result in enforcement action by fire authorities, including fines or prosecution.

A common misconception is that businesses with fewer than five employees do not need a Fire Risk Assessment. While written documentation requirements may differ in very small workplaces, the legal duty to assess fire risk still applies.

Who is responsible for a Fire Risk Assessment?

The duty to manage fire safety lies with the Responsible Person.

Depending on the building, this may be:

• The employer

• The building owner

• A landlord

• A managing agent

• Anyone who has control of the premises

Even when a Fire Risk Assessment is carried out by a professional consultant, the legal responsibility for fire safety cannot be delegated.

The Responsible Person must ensure that the assessment is suitable, sufficient, and regularly reviewed.

Understanding this responsibility is particularly important in multi-occupancy buildings, where duties may be shared between several parties.

Why competence matters in Fire Risk Assessments

Not all Fire Risk Assessments are equal. A thorough assessment requires a strong understanding of:

• Building design and construction

• Fire behaviour and smoke spread

• Active fire protection systems

• Passive fire protection measures

• Evacuation strategies and means of escape

Professional competence is increasingly recognised as a critical factor in fire safety.

Recent industry standards classify fire risk assessors into different competence levels, typically including:

• Basic

• Intermediate

• Advanced

The appropriate level depends on the complexity and risk profile of the building. For example, complex premises such as schools, care homes, and large commercial buildings require assessors with higher levels of expertise.

Professional assessors maintain competence through training, industry engagement, and continuous professional development (CPD) to stay up to date with evolving fire safety regulations and technologies.

What does a Fire Risk Assessment include?

A comprehensive Fire Risk Assessment examines both the physical features of a building and the way fire safety is managed on a day-to-day basis. Key areas typically reviewed include:

• Building layout and construction: Understanding how the building is designed and constructed is critical in assessing how fire could spread and how occupants would evacuate.
• Means of escape: Escape routes are assessed to ensure occupants can evacuate safely in the event of a fire, this includes reviewing exit doors, emergency lighting evacuation strategies and accessibility.
• Fire detection and alarm systems: Assessors review whether these are appropriate for the building and properly maintained. These systems play a critical role in providing early warning and enabling safe evacuation.
• Passive fire protection: those  measures that help prevent fire and smoke from spreading throughout the building, including fire doors, fire stopping and compartmentation.
• Fire safety management: fire safety is not only about equipment and building design – it also depends on effective management practices. From staff training, to fire drills and signage.  Together, these measures form the foundation of an effective fire safety management system.

How often should Fire Risk Assessments be reviewed?

A Fire Risk Assessment should not be treated as a one-off exercise. The law requires assessments to be reviewed regularly to ensure they remain suitable and sufficient.

A common industry approach is to review Fire Risk Assessments annually, although the appropriate frequency depends on factors such as:

• The type of premises

• The level of fire risk

• Changes to the building or occupancy

Assessments should also be reviewed when significant changes occur, such as:

• Structural alterations

• Changes in occupancy

• New equipment or processes

• Fire incidents or near misses

Regular reviews ensure that fire safety measures continue to reflect the current risks within the building.
