When do I need an HMO licence?

Mandatory licensing in England covers HMOs occupied by five or more people forming two or more households who share facilities. Your council may also require a licence for smaller HMOs under additional licensing, or for any rented home under selective licensing.

What is the difference between mandatory, additional and selective licensing?

Mandatory licensing is national and applies to larger HMOs. Additional licensing is a local scheme extending HMO licensing to smaller properties. Selective licensing is a local scheme covering rented homes in a designated area whether or not they are HMOs.

How much does an HMO licence cost?

Fees are set by each council and commonly run from a few hundred pounds to well over a thousand for a five year licence, sometimes with a separate application and grant fee. Check your council's current fee schedule rather than a national figure.

What are the minimum room sizes for an HMO?

National standards set minimum floor areas for rooms used as sleeping accommodation, with a smaller minimum for a child under ten. Councils can impose higher standards through licence conditions, and floor area under a low ceiling height is generally discounted.

What is the penalty for an unlicensed HMO?

The council can issue a civil penalty of up to £30,000 per offence or prosecute. Tenants and the council can also apply for a rent repayment order recovering up to twelve months of rent, and possession claims become far harder while unlicensed.

Does an HMO licence cover fire safety?

Licence conditions usually include fire detection, escape routes and fire doors, but the duty comes from fire safety and housing health and safety law, not the licence itself. A fire risk assessment is expected regardless.

Do HMO rules differ in Wales and Scotland?

Yes. Wales requires landlord and agent registration and licensing through Rent Smart Wales alongside HMO licensing, and Scotland operates its own landlord registration and HMO licensing regime with different thresholds.

Can I be licensed and still fail an inspection?

Yes. A licence is a permission, not a certificate of compliance. Councils inspect against the housing health and safety rating system and can serve improvement notices at any time.

HMO licence: when you need one and what it demands

HMO licensing catches more landlords than any other rule, usually because a council scheme changed rather than because the property did. The consequences are serious: civil penalties reaching £30,000, rent repayment orders of up to twelve months' rent, and possession claims that stall while the property is unlicensed. This guide sets out the thresholds, the standards and the records councils actually ask for.

Is your property an HMO?

A house in multiple occupation is a property occupied by three or more people forming two or more households who share a kitchen, bathroom or toilet. A household is a single person or members of the same family, so three friends sharing a flat is an HMO while a couple with children is not.

Being an HMO brings management duties even without a licence: fire precautions, maintenance of shared areas, waste arrangements and displaying the manager's contact details. Licensing is an additional layer on top.

The three licensing regimes

Mandatory licensing: nationwide in England, five or more occupiers in two or more households sharing facilities.
Additional licensing: a local scheme extending HMO licensing to smaller HMOs, usually three or four occupiers.
Selective licensing: a local scheme covering all privately rented homes in a designated area, HMO or not.
Wales: registration and licensing through Rent Smart Wales in addition to HMO licensing.
Scotland: separate landlord registration plus HMO licensing with its own thresholds and conditions.

Local schemes are time limited and are re-designated regularly. Check your council's current designations at least once a year, and again before buying in an area you do not already let in.

Applying for a licence

1
Work out whether the property is an HMO
Three or more occupiers forming two or more households and sharing a kitchen, bathroom or toilet makes it an HMO. Whether it needs a licence is a separate question.
2
Check mandatory licensing
Mandatory licensing applies across England to HMOs with five or more occupiers in two or more households, regardless of how many storeys the building has.
3
Check your council's own schemes
Many councils operate additional licensing for smaller HMOs, or selective licensing covering all rented homes in a designated area. These are local, they change, and they are the usual reason a landlord is unlicensed without realising.
4
Measure the rooms before applying
National minimum room sizes apply for sleeping accommodation, and councils set amenity standards for kitchens, bathrooms and fire safety. Measure and photograph each room first, because the application asks.
5
Gather the paperwork
Gas safety record, EICR, fire alarm and emergency lighting certificates, fire risk assessment, floor plan, EPC, proof of ownership and management arrangements are the usual list.
6
Apply, pay and diarise renewal
Licences typically run up to five years. Apply before the current one expires, since operating unlicensed is an offence even if the application is simply late.

Standards and licence conditions

Expect conditions covering room sizes, the ratio of kitchens, bathrooms and toilets to occupiers, fire detection appropriate to the property's layout, fire doors and escape routes, gas and electrical safety, and the maximum number of occupiers permitted.

Councils also assess the applicant. A fit and proper person test looks at previous convictions, housing offences and whether you have any other properties in poor condition, and a licence can be refused or granted to a different manager.

What councils ask to see

In our experience of council requirements across England, the same bundle comes up repeatedly, and the landlords who struggle are the ones assembling it from scratch under a deadline.

Keep a live folder per property containing the gas safety record, EICR, fire alarm and emergency lighting servicing, fire risk assessment, EPC, floor plan with room measurements, tenancy agreements, deposit protection evidence and the licence itself with its expiry date.
