How Often Should a Fire Risk Assessment Be Done? The Complete Guide for UK Businesses, Landlords and Organisations
If you manage a business, own a commercial premises, or operate as a landlord anywhere in the UK, fire safety compliance is a legal obligation you cannot afford to overlook. One of the most common questions our team at Wyvern Risk Management receives is: how often should a fire risk assessment be done? It is a straightforward question, but the answer depends on your building type, your occupancy, and what has changed since your last assessment was carried out.
In this guide, we walk you through everything you need to know - from what a fire risk assessment actually involves, to the specific circumstances that require you to act sooner than your scheduled review. Whether you are based in Bristol, Bath, Gloucester, Cardiff, Exeter, Newport, or anywhere across the South West, Wyvern Risk Management is here to make compliance straightforward.
What Is a Fire Risk Assessment and Why Does Every Business Need One?
A fire risk assessment is a formal, structured evaluation of your premises carried out to identify fire hazards, assess the level of risk those hazards present to the people who use the building, and determine what fire safety measures need to be in place to manage that risk effectively.
Far from being a tick-box exercise, a properly conducted fire risk assessment forms the foundation of your entire fire safety management strategy. It informs your emergency procedures, your fire safety equipment requirements, your staff training obligations, and your ongoing maintenance priorities. Without a current, accurate fire risk assessment in place, every other aspect of your fire safety approach is built on shaky ground.
What Does a Professional Fire Risk Assessment Cover?
A thorough fire risk assessment carried out by an accredited assessor will examine every aspect of your premises and the activities that take place within it.
Identification of ignition, fuel, and oxygen sources
Your assessor will systematically identify all potential sources of ignition - from electrical equipment and heating systems to human behaviour - alongside the fuel loads and oxygen sources that could allow a fire to develop and spread.
Assessment of who is at risk and how
Everyone who uses or visits your building must be considered, including employees, customers, contractors, and any vulnerable individuals such as those with mobility difficulties, sensory impairments, or cognitive conditions who may require additional assistance to evacuate safely.
Evaluation of existing fire safety measures
Your assessor will assess the adequacy of your current fire detection and alarm systems, emergency lighting, fire extinguishers, fire doors, escape routes, and signage - identifying any gaps or deficiencies that need to be addressed.
A written record of findings and actions
For businesses with five or more employees, the findings must be formally recorded in writing. This record forms the basis of your compliance documentation and should be immediately available for inspection by the Fire and Rescue Authority.
A prioritised action plan
Where improvements are required, your assessor will provide a clear, prioritised list of actions - so you know what needs doing urgently and what can be addressed as part of a planned programme.
How Often Should a Fire Risk Assessment Be Done in the UK - What the Law Actually Says
So, how often should a fire risk assessment be done under UK law? The Regulatory Reform (Fire Safety) Order 2005 - the primary legislation governing fire safety in non-domestic premises across England and Wales - does not specify a fixed review interval. Instead, it requires that your fire risk assessment remains suitable and sufficient at all times. In practice, this means it must accurately reflect the current state of your premises and the risks within it.
How Frequently Should Businesses Review Their Fire Risk Assessment?
The absence of a fixed statutory interval does not mean there is no guidance. Widely adopted best practice - and the approach Wyvern Risk Management recommends to all clients across Bristol, Bath, Gloucester, Cardiff, Exeter and the South West - establishes clear review expectations based on your premises type and risk profile.
Annual review as a minimum standard
For the majority of commercial premises, businesses, and managed properties, an annual review of your fire risk assessment is the recognised baseline. This ensures your assessment reflects any incremental changes to your building, occupancy, or operations over the preceding 12 months.
Every six months for higher-risk premises
Buildings with high occupancy levels, complex layouts, vulnerable residents or service users, or premises that involve hazardous processes or materials should be reviewed at least twice a year. This category includes care homes, HMOs, schools, and hospitality venues.
Immediately following a significant change
Any material change to your premises - whether structural, operational, or in terms of occupancy - requires your fire risk assessment to be reviewed and updated without delay. We cover the specific triggers for this in detail in the next section.
Following any fire-related incident
Even a minor fire, a significant false alarm, or a near-miss situation should be treated as a prompt to review your current assessment and determine whether the circumstances that led to the incident were adequately captured and controlled.
Key Scenarios That Legally Require a New Fire Risk Assessment to Be Carried Out
Knowing how often a fire risk assessment should be done is only part of the picture. There are specific circumstances in which a new or substantially revised assessment becomes a legal necessity - regardless of when your last review took place. Businesses and landlords across Bristol, Bath, Gloucester, Cardiff, Exeter, Newport and the wider South West should be aware of all of these.
Building Changes That Trigger a New Fire Risk Assessment
Physical changes to your premises almost always affect your fire risk profile, sometimes significantly.
Structural alterations or refurbishment works: Any building work that affects the layout, compartmentation, or structure of your premises - including new internal partitions, extensions, changes to stairwells, or modifications to fire door positions - requires your fire risk assessment to be updated to reflect the new building configuration.
Change of use or building purpose
Converting offices to residential accommodation, opening new areas of a commercial premises to the public, or repurposing a building from one use to another changes the fire risk profile fundamentally and requires a fresh assessment before the new use begins.
Alterations to fire safety systems or equipment
Upgrading, removing, or significantly altering your fire detection system, emergency lighting, suppression equipment, or fire door arrangements all have direct implications for your overall fire risk assessment and must be reflected in an updated document.
Occupancy and Operational Changes That Require a Fire Risk Assessment Review
Changes to how your building is used or who uses it are just as significant as physical changes to the structure.
A significant increase in the number of people using the building: Taking on additional staff, expanding customer-facing areas, or welcoming substantially more visitors to your premises changes your evacuation requirements and may affect the adequacy of your existing escape routes, assembly points, and fire safety equipment provision.
Introduction of new processes, equipment, or materials: Any new activity that introduces additional ignition sources, changes the fuel load within the building, or brings hazardous materials onto the premises requires an immediate review of your fire risk assessment to ensure the new risk has been properly assessed and controlled.
A Change Of Responsible Person
When the person with legal accountability for fire safety at your premises changes - whether due to staff turnover, a change in management structure, or a transfer of ownership - reviewing the existing fire risk assessment should be among their first actions in the role.
Incidents and External Factors That Trigger an Immediate Fire Risk Assessment Review
Some circumstances require you to act immediately rather than waiting for your next scheduled review.
Following a fire, near miss, or significant alarm activation:
Any incident involving fire or smoke - however minor it may appear - should be treated as a signal that your risk controls may not have been fully effective. A review of your fire risk assessment in the immediate aftermath of such an incident is both a legal expectation and sound practice.
Following enforcement or inspection feedback:
If a visit from your local Fire and Rescue Authority has resulted in an improvement notice, a requirement notice, or informal feedback identifying concerns, your fire risk assessment must be reviewed and updated to address those findings as a priority.
Following adverse weather, flooding, or significant damage:
Structural damage to your building - from any cause - can compromise fire compartmentation, damage fire safety equipment, and create new fire risks that were not present at the time of your last assessment.
Is a Fire Risk Assessment a Legal Requirement for Businesses and Landlords in the UK?
Yes - and the legal obligations are unambiguous. Under the Regulatory Reform (Fire Safety) Order 2005, a suitable and sufficient fire risk assessment is a legal requirement across a wide range of premises types throughout England and Wales. The Fire Safety Act 2021 and the Fire Safety (England) Regulations 2022 have subsequently strengthened these obligations, particularly in relation to fire doors, external walls, and multi-occupied residential buildings.
Which Premises Are Legally Required to Have a Fire Risk Assessment?
The legal obligation to carry out and maintain a fire risk assessment applies to the majority of non-domestic premises across the UK.
All commercial and business premises
Offices, retail units, warehouses, factories, workshops, restaurants, bars, hotels, and any other premises used for business purposes are required by law to have a current fire risk assessment in place, regardless of size.
Employers with five or more employees
Where five or more people are employed at a premises, the fire risk assessment must be recorded formally in writing and made available for inspection. Businesses employing fewer than five people are still required to carry out an assessment - they are simply not legally required to record it in writing, though doing so is strongly recommended.
Landlords of HMOs and residential buildings
Landlords of Houses in Multiple Occupation and the owners or managers of communal areas in residential buildings are required to maintain a fire risk assessment covering the common parts of the property. Following the Grenfell Tower tragedy, these obligations have been significantly strengthened for buildings over 11 metres in height.
Care homes, schools, and premises housing vulnerable people
Regulated premises housing individuals who may have difficulty evacuating - including care homes, nursing homes, schools, and hospitals - are subject to fire risk assessment requirements under both the RRO and their relevant sector-specific regulatory frameworks, including CQC regulations.
Licensed premises and publicly accessible buildings
Any building to which members of the public have access - including shops, leisure facilities, places of worship, and entertainment venues - must have a current fire risk assessment in place as a condition of use.
What Are the Consequences of Not Having an Up-to-Date Fire Risk Assessment for Your Business?
Understanding how often a fire risk assessment should be done also means understanding what is at stake if you fail to keep yours current. The consequences of non-compliance extend well beyond a financial penalty - and they can be swift.
Legal, Financial and Regulatory Consequences of Fire Risk Assessment Non-Compliance
The risks of operating without a suitable and sufficient fire risk assessment are significant for businesses and landlords across Bristol, Bath, Gloucester, Cardiff, Exeter and the South West.
Enforcement action by the Fire and Rescue Authority
Local Fire and Rescue Authorities have broad powers to inspect premises and take enforcement action where fire safety failings are identified. This can include improvement notices requiring specific actions within a defined timeframe, prohibition notices that close your premises immediately, and in serious cases, criminal prosecution of the Responsible Person.
Personal prosecution of directors, owners, and managers
The Regulatory Reform (Fire Safety) Order 2005 allows for the prosecution of individuals - not just organisations. Directors, owners, landlords, and managers have faced personal conviction and significant fines where negligence in fire safety management has been established.
Invalidation of your insurance cover
The majority of commercial and landlord insurance policies require the policyholder to maintain a current, adequate fire risk assessment as a condition of cover. An out-of-date or absent assessment can give an insurer grounds to refuse a claim - including in the event of a fire causing damage to your property or injury to occupants.
Regulatory consequences for care homes and schools
For CQC-registered care homes and DfE-regulated educational establishments, an inadequate fire risk assessment is a direct risk to your regulatory rating, your continued registration, and your ability to operate. CQC inspectors and Fire Authority officers routinely request fire risk assessment documentation as part of their inspection processes.
The most serious consequence of all
Beyond the legal and financial risks, failing to maintain an up-to-date fire risk assessment means unidentified hazards, inadequate controls, and a greater likelihood of harm in the event of a fire. This is the consequence that matters most - and the one that a professional, accredited fire risk assessment from Wyvern Risk Management is designed to prevent.
