Managing fire safety in commercial properties lies with business owners and commercial landlords. Legal duties require you to keep documentation accurate and up to date, as outdated records can lead to legal repercussions, invalidated insurance, or increased risk to occupants.

This guide from the fire risk assessment experts at Contact One sets out the legal position and recognised industry practice on review intervals. It explains who can carry out a fire risk assessment, when action is required, what events trigger an immediate update and how to keep records aligned with current conditions so your building and the people within it remain protected.

Is a Fire Risk Assessment a Legal Requirement?

According to the Regulatory Reform (Fire Safety) Order 2005, a fire risk assessment is a legal requirement for all premises that are not a single private dwelling.

This legislation applies to commercial premises, workplaces and the common areas of multi-occupied residential buildings. Failing to carry out a proper fire risk assessment can lead to severe consequences such as enforcement notices, prohibition notices, fines and even imprisonment under the Order. Furthermore, non-compliance can result in the potential invalidation of your insurance coverage in the event of a fire.

Who Is Responsible for Fire Risk Assessments?

Under fire safety legislation, legal duties sit with a defined party known as the “Responsible Person”. This is typically the employer, owner, landlord or managing agent of the premises. The Responsible Person holds legal accountability for managing fire safety across the building and can face enforcement action if duties are not met.

The Responsible Person must arrange for a fire risk assessment to be carried out by a competent individual. This means someone with the appropriate knowledge, training and experience to identify hazards, assess risk and recommend suitable control measures.

In practice, responsibility does not always sit with one party alone. In multi-let or mixed-use buildings, duties are often divided between several Responsible Persons. Each party is accountable for the areas under their control.

How Often Must You Review Your Fire Risk Assessment?

In the UK, there is no fixed legal expiry date for a fire risk assessment. However, the law stipulates that the document must be reviewed regularly to keep it up to date. The expectation is that you update the document whenever necessary to reflect the current state of the building.

We recommend reviewing your fire risk assessment at least once a year, or sooner if there are changes to your building or processes. This annual review helps us identify any new potential fire hazards that may have developed over time.

While fire safety law requires that assessments be updated, current UK industry standards provide clearer guidance on formal reassessment frequencies based on the risk profile of the premises.

Recommended Fire Risk Strategy Assessment by Building Type

The required frequency varies based on the size, use and complexity of the premises. Different building types present different levels of risk, which affects how often reviews and reassessments should take place.

  • Low-risk buildings: small, modern, low-rise offices typically require a review every two years, with a full reassessment every four years.
  • Standard commercial buildings: shops and standard office environments should be reviewed annually, with a full reassessment carried out every three to five years.
  • Higher-risk properties: settings such as care homes, hotels or buildings over four storeys require an annual review and a full reassessment every three years, reflecting the increased occupancy risk and evacuation considerations.
  • Highest-risk sites: complex premises, including factories handling flammable materials or heritage buildings, should be reviewed every six months, with a full reassessment completed annually due to the elevated potential for fire spread and structural constraints.

Mandatory Triggers for an Immediate Review

Regardless of your planned review cycle, certain events will make an existing fire risk assessment outdated. When these changes occur, the assessment must be reviewed without delay to reflect the current level of risk and avoid gaps in fire safety management.

You should carry out an immediate review if any of the following apply:

  • Structural alterations: building works, refurbishments, or fit-outs that change the layout, including anything that affects compartmentation or escape routes.
  • Change of use: where the function of the premises changes - for example, converting office space into retail - which introduces different fire risks and occupancy patterns.
  • Introduction of new hazards: bringing hazardous materials, industrial equipment or other fire risks onto the site.
  • Occupancy shifts: a marked increase in staff numbers or the presence of people who may need assistance during evacuation, such as those with mobility issues.
  • Following an incident: any fire, repeated false alarms or a near miss should prompt a review to identify the cause and address any failings in existing controls.

What Does a Comprehensive Assessment Involve?

The primary goal of a fire risk assessment is to evaluate the risk of fire and implement appropriate fire precautions. The process follows a structured methodology to accurately identify potential fire hazards:

  • Identifying potential fire hazards: locating sources of ignition, fuel and oxygen.
  • Evaluating risks to people: assessing the potential risks to staff, visitors and those in communal areas or entrance halls.
  • Reviewing existing fire safety measures: checking general fire precautions, emergency lighting and whether the fire alarm systems are functioning correctly.
  • Inspecting compartmentalisation: reviewing the condition of fire doors, flat entrance doors and front doors in residential settings to ensure adequate protection.
  • Scrutinising passive fire protection: evaluating essential structural elements, such as the integrity of external walls.
  • Recommending mitigation measures: ensuring the emergency plan is robust, checking fire extinguishers and making sure fire and rescue service have clear access to the site.

Recent Changes to Fire Safety Law and Documentation

Maintaining accurate documentation is a vital part of our risk management process. It is mandatory for the 'Responsible Person' to record the findings of the fire risk assessment, including any actions taken or planned, as per the updated Building Safety Act 2022.

Since October 1, 2023, the law requires all businesses in the UK, regardless of size or employee count, to maintain a written record of their full fire risk assessment. Previously, smaller businesses were exempt from this specific requirement, but recent regulatory reform has removed this exception.

Your written record must detail the significant findings, the actions you have taken to prevent fire, and the steps our team will help you take to address any outstanding fire hazards.

Why You Need a Competent Fire Risk Assessor

While an employer may feel capable of conducting their own fire risk assessment in very small, low-risk environments, it's always advised to consult a professional.

A competent fire risk assessor possesses the nuanced knowledge required to identify hidden fire risks that an untrained eye might miss. They understand how complex passive fire protection systems interact and how to properly evaluate multi-occupied residential buildings alongside commercial spaces. By delegating this task to our qualified experts, the responsible person ensures that all legal duties are fully met and potential hazards are neutralised.

Maintaining Your Fire Safety Measures

Completing a fire risk assessment is the starting point. The outcome depends on how effectively the findings are put into practice across the building.

The fire risk assessment experts at Contact One advise clients to maintain fire safety measures through routine checks and consistent upkeep. This includes:

  • Fire alarm testing: test systems on a weekly basis to confirm they activate correctly and can be heard throughout the premises.
  • Escape routes: keep all exits and walkways clear at all times so occupants can leave the building without obstruction.
  • Fire doors: inspect regularly, checking hinges, seals and closers to confirm doors shut properly and maintain compartmentation.
  • Passive fire protection: address any damage or gaps in fire-stopping without delay, particularly after internal works such as cabling or refurbishment.

Managing these elements on an ongoing basis reduces the likelihood of faults going unnoticed and limits the potential for fire to spread, protecting the premises and those within it.

What Does the EICR Inspection Process Involve?

The EICR inspection process is detailed and methodical, combining visual assessments with technical testing. It is carried out in stages to build an accurate picture of the condition of the electrical installation.

  • Pre-inspection preparation: providing the electrical inspector with access to consumer units, sockets, and switches across the property. Any existing documentation, such as previous electrical installation certificates, helps establish the history and expected condition of the system.
  • Visual inspection: reviewing accessible parts of the installation for visible defects and signs of wear. This includes identifying damage, overheating, non-compliant components, poor workmanship and any unsafe alterations made over time.
  • Dead testing and circuit testing: isolating circuits to assess the condition of internal wiring without live current. This involves checking earthing conductors, which direct fault currents safely to ground, and carrying out insulation resistance tests to identify deterioration in cable insulation.
  • Live testing: restoring power to confirm that protective devices operate correctly. This includes testing residual current devices (RCDs) to verify that they disconnect within the required timeframes, reducing the risk of electric shock.
