HMO Licensing Requirements: Property Standards You Must Meet

An HMO licence is not granted automatically. Your property must meet specific standards covering room sizes, fire safety, kitchen and bathroom provision, and general condition. Councils inspect against these standards either before granting the licence or within the first year — and they can attach conditions, refuse the licence, or revoke it if standards are not met.

This guide sets out every requirement in detail so you know exactly what your property needs before you apply.

Minimum Room Sizes

Room size requirements for licensed HMOs were standardised in England from October 2018 under the Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018.

Sleeping rooms

Room use	Minimum floor area
One person aged 10 or over	6.51 sqm
Two persons aged 10 or over	10.22 sqm
One child under 10	4.64 sqm

These are absolute minimums — no room used for sleeping can be smaller than these figures. Councils set these as conditions on the licence and can specify maximum occupancy per room.

How rooms are measured

Floor area is measured wall to wall at a height of 1.5 metres from the floor
Areas under sloping ceilings below 1.5m height are excluded from the calculation
Built-in wardrobes and cupboards are generally included in the measurement
En-suite bathrooms within a bedroom are excluded — only the sleeping/living area counts
Shared rooms (kitchens, lounges) are not subject to the same statutory minimums but must be adequate for the number of occupants

What if a room is below the minimum?

A room that does not meet the minimum size for its intended occupancy cannot be used as sleeping accommodation for that number of people. The council will specify the permitted use and maximum occupancy on the licence. Operating above the stated occupancy is a breach of licence conditions.

Fire Safety Requirements

Fire safety is the area where councils are most demanding — and where non-compliance carries the most serious consequences. HMO fire safety requirements come from multiple sources: the Housing Act 2004, the Regulatory Reform (Fire Safety) Order 2005, the LACORS Housing Fire Safety Guidance (used by most councils as their benchmark), and individual council requirements.

Smoke and heat detection

Mains-wired, interlinked smoke alarms on every storey where there is habitable accommodation
Alarms must be interlinked so that activation of one alarm triggers all alarms in the property
Heat detectors (not smoke alarms) in kitchens — smoke alarms in kitchens produce false alarms
Battery-only alarms are not acceptable for licensed HMOs — mains-wired with battery backup is the minimum standard
Alarms should comply with BS 5839-6 (domestic fire detection standard)

Fire doors

For larger HMOs (typically five or more occupants), fire doors are required to:

All bedrooms (FD30 rated — 30-minute fire resistance)
The kitchen
Any room opening onto the escape route

Fire doors must have:
– Intumescent strips and cold smoke seals
– Self-closing devices
– Correct signage where required

For smaller HMOs (three to four occupants), some councils accept standard doors with self-closers to kitchens. Check your council's specific requirements.

Escape routes

All occupants must be able to escape the building without passing through a high-risk room (typically the kitchen)
Corridors, stairways, and escape routes must be kept clear of obstruction at all times
Emergency lighting is required in some HMOs — particularly larger properties and those where the escape route is internal and unlit
Escape windows may be acceptable for first-floor rooms where the drop height is within permitted limits

Fire risk assessment

You are legally required to carry out a fire risk assessment and keep it under regular review. The assessment must identify fire hazards, people at risk, evaluate the risk, record findings, and implement a plan to reduce risk. Many councils require a professionally prepared fire risk assessment as part of the licence application.

Fire safety equipment

Fire blankets in kitchens
Fire extinguishers in communal areas (some councils require these; others consider them optional)
Emergency escape signage where required

Kitchen Facilities

The kitchen must be adequate for the number of occupants. Most councils follow LACORS guidance:

Shared kitchen for up to 5 occupants

Cooker with four burners and oven (or equivalent hob and separate oven)
Sink with hot and cold running water and drainer
Worktop — minimum 500mm deep
Refrigerator with adequate capacity (most councils specify minimum capacity per person)
Food storage — cupboard space for each occupant
Electrical sockets — minimum four double sockets (in addition to those used by fixed appliances)
Waste bin of adequate capacity
Ventilation — mechanical extract ventilation to the outside air

For 6–10 occupants

Most councils require additional provision:

A second set of cooking facilities (additional cooker or combination microwave/oven)
A second sink (or dishwasher as an acceptable alternative in some councils)
Larger refrigerator/freezer capacity or a second unit
Additional worktop and storage space

For 11+ occupants

At this scale, councils typically require a second kitchen or a significantly enlarged single kitchen with duplicate facilities.

Communal vs individual kitchens

Some HMOs, particularly purpose-built ones, provide individual kitchenettes in each bedroom. Where this arrangement is proposed, check with the council whether it meets their definition of adequate kitchen facilities — some councils still require a shared kitchen even where rooms have individual cooking facilities.

Bathroom and Toilet Facilities

Minimum provision

The standard ratio used by most councils:

1 bathroom (bath or shower) per 5 occupants
1 toilet per 5 occupants
1 wash hand basin per 5 occupants (or per bedroom if en-suite)

For practical purposes:

Occupants	Minimum bathrooms	Minimum toilets
3–5	1	1
6–10	2	2
11–15	3	3

These are minimums. Councils may require more depending on the property layout and the proximity of facilities to bedrooms. discover more facilities count towards the ratio.

Standards for bathrooms

Hot and cold running water
Adequate ventilation (mechanical extract where no openable window)
Adequate heating
Splashback tiling or waterproof panelling around baths and showers
Lockable doors for privacy

Heating and Energy Efficiency

Adequate fixed heating in every habitable room — portable heaters do not count
Gas central heating is the most common arrangement; electric panel heaters are acceptable
The property must have a valid EPC (Energy Performance Certificate) rated E or above (current minimum standard; check for upcoming changes to minimum EPC requirements)
All gas appliances must be checked annually by a Gas Safe registered engineer, with a valid gas safety certificate on file

Electrical Safety

A valid Electrical Installation Condition Report (EICR) is required — conducted by a qualified electrician, valid for five years
The EICR must show a satisfactory result with no Code 1 (danger present) or Code 2 (potentially dangerous) issues unresolved
PAT testing of landlord-supplied electrical appliances is recommended (and required by some councils)

General Property Condition

The property must not have any Category 1 hazards under the Housing Health and Safety Rating System (HHSRS). Category 1 hazards include:

Falls on stairs (defective handrails, uneven treads)
Damp and mould growth (inadequate ventilation, water ingress)
Excess cold (insufficient heating or insulation)
Electrical hazards (exposed wiring, overloaded circuits)
Fire risks (blocked escape routes, no fire detection)
Structural collapse and falling elements (defective walls, ceilings, roofs)

Councils assess HHSRS hazards during inspections and can take enforcement action independently of the licensing process.

Management Obligations

As an HMO licence holder, you must comply with the Management of Houses in Multiple Occupation (England) Regulations 2006 (or the 2007 equivalent for Wales). Key obligations:

Maintain common parts — hallways, stairways, kitchens, bathrooms kept clean, in good repair, and free from obstruction
Maintain water supply and drainage — ensure adequate supply, prevent contamination, keep drainage clear
Supply household information — provide contact details for the manager/licence holder to all occupants
Maintain the structure and exterior — keep the building in good repair, including the roof, external walls, windows, and gutters
Maintain gas and electricity installations — annual gas safety check, five-yearly EICR
Manage waste — provide adequate bins and ensure regular collection
Maintain fire safety measures — keep fire alarms working, fire doors properly maintained, escape routes clear

Failure to comply with management regulations is a separate offence from licence breaches and can result in fines or civil penalties.

Next Steps

Meeting HMO licensing requirements is a matter of preparation and attention to detail. The standards are clearly defined, the measurements are straightforward, and the fire safety requirements follow established guidance. Properties that are well-maintained and managed to a reasonable standard will typically meet the requirements with minimal additional work.

If you are buying an HMO or remortgaging, lenders will expect the property to be licensed and compliant. Contact The HMO Mortgage Broker for advice on how property standards interact with your mortgage application — particularly if the property requires works to meet licensing conditions.

Frequently Asked Questions

What property standards must I meet for an HMO licence?

Your property must meet: minimum room size standards (6.51 sqm single, 10.22 sqm double), adequate bathroom facilities (1 per 4-5 occupants), kitchen facilities appropriate for the number of occupants, fire safety requirements (alarms, doors, escape routes), adequate heating in all habitable rooms, natural lighting and ventilation, and safe electrical and gas installations.

Do I need to meet standards before applying for an HMO licence?

You should meet all safety standards before tenants move in, but you can apply for the licence while bringing the property up to standard. Many councils conduct pre-licence inspections and may issue a licence with improvement conditions giving you a deadline to complete specific works. Critical safety items (fire alarms, escape routes) must be in place before occupation.

How strict are HMO licensing inspections?

Inspection thoroughness varies by council, but environmental health officers typically check: fire safety equipment and escape routes, room sizes and maximum occupancy, kitchen and bathroom facilities, structural condition, damp and ventilation, heating systems, electrical and gas safety certificates, waste management, and outdoor areas. Any deficiencies will be noted and improvement timescales set.

Can I appeal an HMO licence decision?

Yes, you can appeal to the First-tier Tribunal (Property Chamber) against: a refusal to grant a licence, conditions attached to a licence, a variation of licence conditions, or a revocation of a licence. The appeal must be made within 28 days of the decision. The tribunal can confirm, reverse, or vary the council's decision. Seek legal advice before appealing as the process can be complex.
