Fire Risk Assessment: The Complete Guide for Businesses and HMO Landlords
20/11/2025
A fire risk assessment is one of the most important safety and legal requirements for any business or landlord in the United Kingdom. It protects people, property and livelihoods, and ensures compliance with strict UK fire safety laws. Whether you manage a business premises, oversee a block of flats or operate an HMO, this guide will walk you through every part of the fire risk assessment process.
This long-format guide explains what a fire risk assessment is, who needs one, when you need one, how it works, how much it costs, what your legal responsibilities are and how to remain compliant throughout the year.
A fire risk assessment is a structured and legally mandated review of a building or premises that identifies potential fire hazards, evaluates the level of risk and determines the measures required to reduce or eliminate that risk. It is required under UK law for nearly all non-domestic buildings and all types of rented residential accommodation.
A competent fire risk assessment must include the following tasks:
This includes assessing sources of ignition, fuel and oxygen. Examples include electrical equipment, overloaded sockets, cooking appliances, stock storage, flammable materials, faulty wiring and heating equipment.
This involves examining who uses the building and who may be more vulnerable. Examples include children, elderly individuals, disabled people, lone workers, night shift staff, tenants and regular visitors.
This step determines how likely a fire is to start and what impact it could have. Measures may include removing hazards, installing fire detection systems, improving escape routes, upgrading fire doors, fitting signage or ensuring extinguishers are correctly placed.
If a business employs five or more people or if the property is an HMO or commercial building, written records are required by law. A documented risk assessment protects you during inspections and compliance audits.
This includes creating evacuation plans, establishing assembly points, communicating routes to staff or tenants, and ensuring everyone knows how to exit safely.
Fire safety is not a one-time activity. Assessments must be updated regularly and whenever risks change.
All UK fire safety legislation for England and Wales is governed by the Regulatory Reform Fire Safety Order 2005. This requires that there must always be a Responsible Person who ensures that fire risk assessments are completed and regularly reviewed.
Further legal updates include:
Failing to comply can result in prosecution, unlimited fines and even prison sentences.
A fire risk assessment ensures potential hazards are identified before they become dangerous. It helps prevent fires, protect the lives of employees, tenants and visitors and reduce harm to vulnerable individuals.
A single fire can cost a business or landlord thousands of pounds in repairs, insurance disputes, lost income and legal claims. A valid risk assessment:
Businesses and landlords who fail to meet fire safety standards often appear in public enforcement notices. This damages trust and credibility. A strong fire safety record protects your reputation.
A fire risk assessment is legally required for:
Any non-domestic premises must have a fire risk assessment. This includes:
If the public or employees access the building, a fire risk assessment is required.
Landlords must complete fire risk assessments for:
This includes:
This is the individual or organisation legally responsible for fire safety. It may include:
The Responsible Person must ensure the assessment is carried out by someone competent.
A fire risk assessment is required as soon as you become responsible for a building. New businesses, new landlords and new HMO licence applicants must have one before trading or renting begins.
A review is required:
There is no official expiry date in law. However, UK guidance and industry standards consider assessments valid for 12 months due to changing risks, tenant behaviour and equipment wear.
This includes HMOs, flats, maisonettes and shared accommodation. Communal areas always require assessment.
All business premises must have a fire risk assessment, regardless of size or industry.
Examples include:
Shared spaces often present the highest risk. This includes:
Fire risk assessments fall into four recognised categories. These categories help determine how intrusive the inspection must be, how much access is required and what level of investigation is needed to identify structural and fire safety risks. The type required depends on the age of the building, its construction, the level of fire safety concern and the complexity of the layout.
Below is a detailed explanation of each type, how they work, what they include and when they are required.
A Type 1 assessment is the most common fire risk assessment in the UK. It is a non destructive inspection focused on all communal areas that residents or occupants share. It does not require any opening of walls, floors, ceilings or service risers. Its purpose is to check visible fire safety measures and confirm that escape routes, fire doors, alarms and other critical systems are present and functioning.
A Type 1 assessment typically covers:
A Type 1 assessment does not inspect:
A Type 2 assessment is a destructive inspection of the communal areas only. It is more intrusive and is used when there are concerns that non visible fire safety issues may be present. This type of assessment requires opening up parts of the building fabric, such as walls, service risers, ceilings and floors, to inspect compartmentation and fire stopping.
The assessor works alongside contractors who carry out safe and controlled destructive access.
This assessment may involve:
A Type 2 assessment is often recommended when:
This type is more complex due to destructive access. It can be disruptive and therefore must be planned carefully, usually outside peak occupancy hours.
A Type 3 assessment expands on the Type 1 assessment. It includes both communal areas and the inside of individual flats or private rooms. It is still non destructive and does not require damaging walls or ceilings. It allows the assessor to check internal layouts, lifestyle risks and fire safety equipment inside private living spaces.
This is particularly important in HMOs, where individual tenants may conduct activities that significantly increase fire risks.
The inspector will check:
A Type 3 assessment is recommended when:
A Type 4 assessment is the most comprehensive and intrusive of all fire risk assessments. It includes both communal areas and individual flats or private rooms and involves destructive inspection in all areas. It is used only in high risk or older buildings where there are concerns about structural integrity, compartmentation, fire stopping or legacy construction work.
This type of assessment is complex, expensive and disruptive but provides the most accurate information.
A Type 4 assessment may involve:
A Type 4 assessment is usually recommended when:
Inspect all areas of the building. Look for ignition sources such as electrical faults, heaters, cooking appliances and smoking materials. Identify fuel sources such as paper, timber, rubbish, stock and flammable liquids.
Consider everyone who uses the property, including tenants, employees, contractors, visitors, cleaners and vulnerable persons.
This is the critical stage. Actions can include:
A written record must include:
Document evacuation procedures, fire drills, assembly points and communication instructions.
Reviews should occur annually and after any major change.
A typical checklist includes:
Examples may include findings such as:
To comply with HMO licensing, most councils require:
HMOs carry higher risks due to increased occupants and tenant behaviour. Assessors must also consider room layouts, smoking areas, clutter risks and cooking risks.
Councils often introduce additional requirements via licensing schemes. These may include stricter alarm systems, enhanced emergency lighting or more frequent inspections.
Explain categories such as LD3, LD2 and LD1 for residential settings and Grade A or Grade D alarms.
Identify correct types:
Emergency lighting is essential for escape routes, particularly in HMOs with complex layouts.
Fire doors must be maintained and never wedged open. They must have correct seals, hinges, closers and latches.
Escape route markers, fire action notices and extinguisher identification signs may be required.
Costs vary depending on size, risk and complexity. Typical ranges:
These include:
Low cost assessments often lack detail. They may be rejected by insurers or enforcing authorities.
A competent person must have sufficient training, knowledge and experience. They must understand fire science, building regulations and UK fire safety law.
Simple premises may allow an internal assessment. However, competent assessors are strongly recommended for HMOs and complex commercial premises.
These include:
Fines can reach tens of thousands of pounds.
Severe breaches can lead to imprisonment.
Insurers may reject claims if a fire risk assessment is missing or outdated.
Key issues include electrical equipment, printers and escape route management.
Stock storage, public access and staff training are critical factors.
Grease build up, cooking equipment and extraction systems must be addressed.
These may contain chemicals, large equipment and specialist risks.
These buildings require strong compartmentation and robust alarm coverage.
Care homes require enhanced safety due to high vulnerability.
Avoid overloaded sockets, damaged cables and hazardous extension cords.
Ensure extraction systems are clean and monitored.
Provide designated areas away from fuel sources.
Store oils, chemicals and fuels safely.
Regular cleaning reduces fire spread.
Yes. All businesses and all HMOs require a fire risk assessment by law.
