HMO Licence Property Maintenance Requirements in London: What Landlords Must Provide

HMO Licence Property Maintenance Requirements in London

Houses in Multiple Occupation represent a significant proportion of the London private rental market. The additional complexity of managing multiple occupants in shared accommodation is reflected in a more demanding compliance framework than applies to single-tenancy properties. Understanding the specific physical standards, fire safety obligations, and annual certification requirements is essential for any landlord operating in the HMO sector in London.

What Qualifies as an HMO and When Is Licensing Required?

A property is classified as an HMO under the Housing Act 2004 if it is occupied by three or more tenants forming two or more separate households who share one or more basic amenities such as a kitchen, bathroom, or toilet. Mandatory HMO licensing is required for properties occupied by five or more tenants forming two or more households. London boroughs also have discretionary powers to extend licensing to smaller HMOs, and many have done so. Landlords should check their specific borough requirements — the definition of what requires a licence varies between London local authorities.

Physical Standards Under the HMO Management Regulations 2006

The Management of Houses in Multiple Occupation (England) Regulations 2006 set out specific maintenance obligations for HMO landlords. These are ongoing duties, not one-off requirements at the point of letting:

Means of escape from fire: All escape routes must be kept clear and maintained in good structural condition at all times. Fire doors on escape routes must be self-closing, correctly hung, and free from defects that would prevent them from closing fully onto their frames. Blocked or propped-open fire doors are one of the most commonly cited deficiencies in London HMO inspections.

Shared facilities: All communal kitchens, bathrooms, and toilets supplied by the landlord must be maintained in repair and good working order. A broken hob in a shared kitchen, a non-functioning shower in the sole bathroom, or a toilet that does not flush are all management regulation failures that can result in enforcement action.

Electrical appliances: Any electrical appliances supplied by the landlord as part of the tenancy — white goods, cooking appliances, electric heaters — must be maintained in a safe condition. PAT testing of supplied appliances is the standard method of demonstrating compliance, though the regulations do not specify a mandatory testing interval.

Gas appliances and flues: All gas appliances and their associated flues must receive an annual Gas Safe inspection. The CP12 Gas Safety Certificate must be renewed every 12 months without exception and copies provided to tenants.

Minimum Bedroom Sizes

Since October 2018, mandatory HMO licences in England must include conditions that ensure minimum bedroom sizes are met. The prescribed minimum floor areas are: 6.51 square metres for a room occupied by a single adult; 10.22 square metres for a room occupied by two adults; and 4.64 square metres for a room occupied solely by a child under the age of 10. Rooms below 4.64 square metres cannot be used as sleeping accommodation at all. Local authorities can require landlords to reduce the number of permitted occupants in a room that does not meet the minimum size for the current usage. Failure to comply with room size conditions is a breach of the licence and can result in financial penalties.

Fire Safety Requirements

All HMOs require a fire risk assessment carried out by a competent person. The assessment identifies fire hazards, evaluates the risk to occupants, and specifies the protective measures required. The minimum fire detection standard for a standard small HMO is interlinked smoke alarms on every floor of the property, plus a heat alarm in the kitchen. All detectors must be interlinked so that activation of one triggers all others in the property. A carbon monoxide alarm is required in any room containing a solid fuel burning appliance, a gas boiler, or a gas fire.

Larger HMOs — typically those with more than two storeys or six or more occupants — will usually require emergency lighting on escape routes, more sophisticated fire detection systems, and fire suppression measures such as fire blankets or sprinkler systems, depending on the risk assessment findings.

Annual Compliance Obligations

The annual compliance cycle for a London HMO includes: CP12 Gas Safety Certificate for all gas appliances, renewed within 12 months of the previous certificate; EICR (Electrical Installation Condition Report) covering the fixed electrical installation, required every five years; PAT testing for all landlord-supplied portable electrical appliances; fire alarm system test and log (quarterly testing is standard best practice); emergency lighting test and log where applicable; and annual review of the fire risk assessment, with a full reassessment following any material change to the property or its occupation pattern.

Selective Licensing in London Boroughs

Several London boroughs operate selective licensing schemes that extend licensing requirements beyond mandatory HMO licensing to cover all privately rented properties, or specific categories of properties, within defined areas. Newham was an early adopter of borough-wide selective licensing. Tower Hamlets, Waltham Forest, Southwark, and other boroughs have implemented schemes of varying scope. A landlord operating in London should check their specific borough council website to confirm whether selective licensing applies to their property, as letting without a required licence can result in a rent repayment order requiring the landlord to return up to 12 months of rent to the tenant.
