Guide to fire compartmentation - How to stop fire spreading in your commercial premises with fire compartmentation

Every business, regardless of size or sector, has a legal and moral duty to protect its employees, customers, and assets from fire. While fire alarms and suppression systems are vital, the foundation of all fire safety planning lies in a comprehensive fire risk assessment. For businesses, this process is not optional — it is a critical requirement under law, and one that has far-reaching implications for safety, compliance, and long-term success.

What Is a Fire Risk Assessment?

A fire risk assessment is a structured evaluation of a building and its operations to identify fire hazards, assess the risks they pose, and put in place measures to reduce or eliminate them. Conducted by trained professionals, it is a detailed process that goes beyond simply checking smoke detectors. It involves a full review of the premises, the people who use it, and the procedures in place for fire prevention and evacuation.

At its core, a fire risk assessment aims to answer five key questions:

  1. What could cause a fire to start?

  2. Who could be at risk?

  3. What safeguards are in place already?

  4. What further action is needed to reduce risk?

  5. How will fire safety be maintained going forward?

By systematically addressing these areas, businesses gain a clear picture of their fire safety position and a practical action plan for improvement.

Legal Requirements for Businesses

In the UK, the Regulatory Reform (Fire Safety) Order 2005 places a duty on employers and building owners to carry out regular fire risk assessments. The law states that the “responsible person” — often a business owner, landlord, or facilities manager — must ensure that an assessment is conducted and kept up to date.

Failure to comply is a serious offence. Businesses found without a valid fire risk assessment can face unlimited fines, prosecution, and in the most severe cases, imprisonment of those deemed responsible. Beyond the legal implications, insurers may also refuse to honour claims if a fire occurs and no up-to-date assessment is in place.

The Business Benefits of Fire Risk Assessments

While compliance is the starting point, there are many additional reasons why fire risk assessments are essential for businesses:

  • Protecting Lives – The primary aim of any assessment is to ensure people can escape safely in the event of a fire.

  • Reducing Fire Hazards – Proactive identification of risks, such as faulty wiring or blocked exits, helps prevent incidents before they occur.

  • Safeguarding Assets – Protecting property, equipment, and stock reduces the financial and operational impact of fire.

  • Business Continuity – A serious fire can cause devastating disruption. By planning ahead, businesses minimise downtime and maintain customer trust.

  • Enhancing Reputation – Demonstrating a strong commitment to fire safety builds confidence among employees, clients, and stakeholders.

What Does a Fire Risk Assessment Involve?

A thorough fire risk assessment follows a clear process:

  1. Identifying Fire Hazards
    Potential ignition sources, flammable materials, and unsafe practices are recorded.

  2. Identifying People at Risk
    Consideration is given to employees, visitors, and particularly vulnerable individuals such as the elderly or disabled.

  3. Evaluating and Reducing Risks
    Existing safety measures are reviewed, and improvements recommended — such as installing fire doors, alarms, or sprinkler systems.

  4. Recording and Implementing Findings
    A written record is created, outlining hazards, risks, and the steps needed to mitigate them. Businesses must then act on these recommendations.

  5. Reviewing and Updating
    Fire risk assessments are not one-off exercises. They must be reviewed regularly, especially after changes to the building, staffing, or operations.

How Often Should Fire Risk Assessments Be Carried Out?

For most businesses, assessments should be reviewed at least once a year. However, additional reviews are necessary if there are significant changes — such as building alterations, changes in occupancy, or the introduction of new processes or equipment. A proactive approach ensures that risks remain controlled and compliance is maintained.

The Role of Professional Assessors

While the law allows businesses to conduct their own assessments, in practice this can be complex and risky. Fire safety legislation is detailed, and missing a critical hazard could put lives in danger and expose a company to liability. Engaging a professional assessor ensures that assessments are carried out with expert knowledge, precision, and compliance in mind.

At Artius, assessments are undertaken by highly trained fire safety specialists who follow industry best practice and provide businesses with clear, actionable reports.

Integrating Fire Risk Assessments into Business Strategy

For forward-thinking organisations, fire risk assessments should be more than a compliance requirement. They can form part of a wider risk management strategy, aligning safety with operational resilience. By embedding fire safety into business culture, companies create workplaces that are not only legally compliant but also safer, more productive, and more reassuring for staff and customers alike.

Conclusion

Fire risk assessments are not simply a box-ticking exercise. They are the cornerstone of business fire safety, providing a clear framework for protecting lives, property, and reputation. By investing in regular, professional assessments, businesses can demonstrate compliance, reduce risk, and build resilience against one of the most devastating threats any organisation can face.

For every business, large or small, the message is clear: a robust fire risk assessment is not just a legal requirement — it is a business imperative.
