Houses in multiple occupation present some of the most significant and complex fire safety challenges in the residential sector.
The combination of multiple occupants sharing common spaces, varied patterns of occupancy and behaviour, shared cooking and laundry facilities, and the potential for a wide range of electrical and cooking equipment to be used simultaneously creates a fire risk profile that is fundamentally different from that of a single-family home.
And the consequences of fire in an HMO can be catastrophic.
Multiple occupants sleeping in a building where a fire breaks out in a shared kitchen, a communal hallway, or a neighbouring bedroom have far less time to escape than the occupants of a conventional home, and far less certainty that the person in the next room has been alerted and is able to get out safely.
For landlords, the legal obligations that flow from this elevated risk are substantial, specific, and rigorously enforced.
What is an HMO?
Under Section 254 of the Housing Act 2004, a house in multiple occupation is a building or part of a building occupied by three or more people who form two or more separate households, and who share or lack exclusive use of basic amenities such as a bathroom, toilet, or cooking facilities.
The definition captures a wide range of property types, including traditional bedsit properties, shared houses occupied by groups of unrelated individuals, converted properties with self-contained or partially self-contained units, and purpose-built blocks of bedsits or studio flats.
Mandatory HMO licensing, introduced under the Housing Act 2004 and extended by the Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licence) (England) Regulations 2018 (SI 2018/221), applies to HMOs occupied by five or more people forming two or more households, regardless of the number of storeys.
Many local authorities also operate additional licensing schemes that extend licensing requirements to smaller HMOs.
Landlords must check with their local authority to establish which licensing requirements apply to their properties.
The Legal Framework for Fire Safety in HMOs
The fire safety obligations that apply to HMO landlords derive from several overlapping pieces of legislation.
The Regulatory Reform (Fire Safety) Order 2005 (SI 2005/1541) applies to the common parts of HMOs, including hallways, stairwells, landings, shared kitchens, and other communal areas.
Under Article 9 of the RRO, the Responsible Person for the common parts of an HMO is required to carry out a suitable and sufficient fire risk assessment and to implement and maintain appropriate fire safety measures based on its findings.
In an HMO, the Responsible Person is typically the landlord, though it may be a managing agent where one has been appointed with day-to-day management responsibilities.
The Housing Act 2004 and the Management of Houses in Multiple Occupation (England) Regulations 2006 (SI 2006/372) impose additional specific fire safety obligations on HMO landlords, including requirements to ensure that the property is provided with adequate means of escape from fire, that the means of escape are kept free from obstruction, that adequate fire detection and firefighting equipment is provided and maintained, and that all means of escape and fire safety equipment are maintained in good repair and working order.
The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 (SI 2022/702), which came into force on 1st October 2022, require landlords of all privately rented properties, including HMOs, to ensure that at least one smoke alarm is installed on each storey used as living accommodation, and that alarms are in working order at the start of each new tenancy.
Fire Risk Assessment in HMOs
The fire risk assessment is the foundation of fire safety management in any HMO.
It must be carried out by a competent person with sufficient knowledge and experience of both fire safety and the specific characteristics of HMOs.
The assessment must identify all fire hazards present in the property, including cooking equipment, electrical installations and portable electrical equipment, the storage of combustible materials, smoking by occupants, and any other hazard specific to the property and its occupants.
It must evaluate the risks those hazards pose to the specific occupants of the HMO, taking into account the number of occupants, their characteristics and any particular vulnerabilities, the layout of the property, and the fire safety measures currently in place.
For HMOs with five or more occupants, the significant findings of the fire risk assessment must be recorded in writing under the requirements of the RRO.
For smaller HMOs, recording the assessment in writing is still strongly advisable as evidence of compliance.
The fire risk assessment must be reviewed regularly and updated whenever significant changes are made to the property, its use, or its occupancy.
Fire Detection and Alarm Systems
Adequate fire detection is one of the most critical fire safety measures in any HMO.
The standard expected for fire detection in HMOs is set out in BS 5839-6:2019, which provides guidance on the design, installation, commissioning, and maintenance of fire detection and alarm systems in domestic premises including HMOs.
For most HMOs, a Grade D, Category LD2 system comprising mains-powered, interlinked smoke alarms with battery backup in all circulation areas and heat alarms in kitchens is considered the minimum appropriate standard.
The key requirement is that all alarms are interlinked, so that when one alarm activates all alarms in the property sound simultaneously, ensuring that all occupants are alerted regardless of where in the property the fire starts.
Smoke alarms should be installed in all circulation areas including hallways, landings, and corridors, and in all rooms used for sleeping accommodation.
Heat alarms, rather than smoke alarms, should be installed in kitchens, where the normal activities of cooking would cause unacceptable levels of false alarms from a smoke alarm.
Carbon monoxide detectors must be installed in any room that contains a fixed combustion appliance, as required by the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022.
The fire detection system must be tested regularly, with alarms tested at least monthly, and maintained in good working order throughout the tenancy.
Means of Escape
The means of escape from an HMO is one of the most critical and most complex fire safety considerations for landlords.
The layout of many HMO properties, particularly those converted from single-family houses, means that the means of escape may be limited and that occupants in upper floor rooms may be particularly vulnerable.
In most HMOs, the primary means of escape will be through the main entrance door and via the staircase to the ground floor.
Where rooms open directly onto the staircase, the protection of the staircase from fire and smoke is of critical importance, as it is the only means by which occupants on upper floors can escape.
In properties where the staircase is not adequately protected, additional measures may be required, including the installation of a protected lobby, the upgrading of fire doors and their frames, and the enhancement of the fire detection system.
The adequacy of the means of escape must be assessed as part of the fire risk assessment, and any deficiencies must be addressed as a matter of priority.
Fire Door Inspections in HMOs
Fire doors are among the most important passive fire protection measures in any HMO, and their inspection and maintenance is a legal obligation that must be taken seriously by every landlord.
A fire door that fails to perform in a fire is not just a compliance failure.
It is a failure that can cost lives, by allowing fire and smoke to spread beyond its room of origin and into the escape routes on which occupants depend.
Under Article 17 of the RRO, the Responsible Person is required to ensure that fire doors are maintained in an efficient state, in efficient working order, and in good repair.
The Management of Houses in Multiple Occupation (England) Regulations 2006 require landlords to ensure that all means of escape, including fire doors, are maintained in good repair and free from obstruction.
Fire doors in HMOs should be inspected at least quarterly, with more frequent inspection in properties where doors are subject to heavy use or where previous inspections have identified recurring deficiencies.
Each inspection should assess the condition and integrity of the door leaf, checking for damage, warping, or unauthorised modification.
It should check the condition of the door frame and its fit within the surrounding structure.
It should check the intumescent seals and smoke seals, confirming they are continuous, undamaged, and correctly fitted.
Intumescent seals expand in the heat of a fire to seal the gap between the door and its frame, preventing the passage of fire.
Smoke seals prevent the passage of cold smoke, which is responsible for the majority of fire fatalities.
The gap tolerances around the door leaf must be checked, confirming that gaps do not exceed 3mm at the sides and top, and do not exceed 8mm at the threshold unless a smoke seal is fitted.
The self-closing device must be confirmed as closing the door fully and positively from any open position without manual assistance.
A fire door that does not close fully provides no meaningful protection to occupants attempting to escape.
All ironmongery including hinges, latches, locks, and overhead closers must be checked and confirmed as correctly installed and functioning as intended.
Where glazing is fitted, the glazing and its beads and seals must be intact and of the appropriate fire-resistant specification.
Appropriate signage must be confirmed, including Fire Door Keep Shut notices on doors that are normally kept closed.
The findings of each inspection must be recorded, deficiencies addressed promptly, and records retained as part of the landlord’s fire safety documentation.
Landlords who do not have the knowledge and experience to carry out fire door inspections to the required standard should commission professional inspections by a qualified inspector.
Electrical Safety and Inspections in HMOs
Electrical faults are one of the leading causes of fire in HMOs, and the management of electrical safety is a critical component of any HMO fire safety strategy.
The Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 (SI 2020/312) require landlords to ensure that the electrical installation is inspected and tested by a qualified and competent person at least every five years, producing an Electrical Installation Condition Report following each inspection.
The EICR must be provided to existing tenants within 28 days of the inspection, to new tenants before they occupy the property, and to the local authority within seven days of a request.
Any remedial work identified as requiring urgent attention must be completed within 28 days, with evidence of completion provided to tenants and the local authority within the same timeframe.
Failure to comply can result in a financial penalty of up to £30,000.
The five-yearly EICR is a mandatory minimum, but should not be treated as the sum total of electrical safety management in an HMO.
The demands placed on the electrical installation by multiple occupants are significantly greater than those of a single-family home, and landlords should consider more frequent inspections in high-occupancy or high-demand properties, particularly where the installation is older or where previous inspections have identified significant remedial works.
The adequacy of socket provision in each room and in communal areas should be assessed as part of the fire risk assessment.
Insufficient sockets encourage the use of extension leads and multi-socket adaptors, which are a well-documented cause of electrical fires in HMOs.
Where socket provision is found to be inadequate, additional sockets should be installed by a competent electrician rather than relying on occupants to manage with extension leads.
Shared kitchens deserve particular attention, as they are used intensively by multiple occupants and house a range of high-power appliances whose combined electrical demands must be adequately served by the installation.
Landlords should have a clear policy on the use of portable electrical appliances by occupants, prohibiting high-risk appliances such as portable electric heaters and hot plates in bedrooms, and requiring any appliances brought in by occupants to be in good condition and used safely.
White goods provided by the landlord should be registered with the manufacturer so that safety recalls can be communicated and acted upon promptly.
Visual inspections of the electrical installation should be carried out as part of the landlord’s regular property inspection regime, with any signs of damage, deterioration, or inappropriate use reported and addressed promptly.
Firefighting Equipment
HMO landlords are required under the Management of Houses in Multiple Occupation (England) Regulations 2006 to provide adequate firefighting equipment in the property.
In most HMOs, this means the provision of a fire blanket in the kitchen, where the risk of cooking fires is greatest.
In larger properties or those with a more complex layout, the provision of portable fire extinguishers in communal areas may also be required.
Any firefighting equipment provided must be of the appropriate type for the risks present, installed in accessible locations, and maintained in good working order with annual servicing by a competent engineer.
Occupants must be informed of the location and basic operation of any firefighting equipment provided, and must be clearly instructed that their primary action in the event of a fire should always be to raise the alarm and evacuate rather than to attempt to fight the fire.
Managing Occupant Behaviour
One of the most challenging aspects of fire safety management in HMOs is the management of occupant behaviour.
Cooking is the leading cause of fire in HMOs, and the shared kitchen environment, where multiple occupants may be cooking simultaneously or leaving cooking unattended, creates a particularly elevated risk.
Smoking is a significant ignition risk, and landlords should have a clear and enforced no-smoking policy within the property.
The use of candles, incense, and other naked flame products in bedrooms and communal areas is another common ignition source that should be addressed in the landlord’s fire safety rules.
The storage of combustible materials in hallways, stairwells, and other escape routes is a recurring problem in HMOs that must be addressed through regular inspection and enforcement.
Landlords must provide all occupants with clear written fire safety information at the start of their tenancy, covering the fire risks present in the property, the fire safety rules they are expected to follow, the location and operation of the fire detection system, the means of escape and evacuation procedure, and what to do if they discover a fire or hear the fire alarm.
This information should be provided in a language and format that is accessible to all occupants, taking into account any language barriers or literacy issues.
Licensing Conditions and Local Authority Enforcement
HMO licensing conditions typically impose specific fire safety requirements that go beyond the minimum required by the RRO and the Management Regulations.
These conditions vary between local authorities but commonly include requirements around the grade and category of the fire detection system, the specification and installation of fire doors, the provision of fire safety information to occupants, the frequency of fire safety inspections, and the keeping of records of fire safety checks and maintenance.
Local authorities have extensive enforcement powers under the Housing Act 2004, including the power to inspect properties, issue improvement notices, issue prohibition orders restricting or preventing occupation, and prosecute landlords who fail to meet their obligations.
Financial penalties of up to £30,000 can be imposed for certain offences, and local authorities can also apply to the First-tier Tribunal for a rent repayment order requiring a landlord to repay up to twelve months rent where serious offences have been committed.
