When does a property need a mandatory HMO licence?

A mandatory HMO licence is required when a property is occupied by 5 or more people forming 2 or more households who share basic amenities like kitchen, bathroom or toilet. This applies across England and Wales. Some councils extend licensing to smaller HMOs via additional licensing schemes.

What is selective licensing?

Selective licensing is a scheme where a council requires a licence for all private rentals in a designated area, regardless of HMO status. This is separate from HMO licensing and aimed at improving standards in problem areas. Many UK cities (parts of Liverpool, Nottingham, Newham, etc.) operate selective licensing schemes.

How much does an HMO licence cost in 2026?

HMO licence fees vary significantly by local authority — typically £500 to £1,500 for a 5-year licence in most areas, but some London boroughs and major cities charge £1,000–£2,000+. Always check your specific council's current fee schedule before budgeting.

What are the HMO minimum room sizes?

The national minimum for sleeping rooms in mandatory licensable HMOs in England is 6.51m² for one person over 10, 10.22m² for two people over 10, and 4.64m² for one child under 10. Local authorities often impose higher minimums. Rooms below the floor area cannot be let as bedrooms.

What is the fit and proper person test?

Before granting an HMO licence, the local authority checks that the licence holder is 'fit and proper' — looking at past convictions (especially fraud, violence, sexual or drug offences), housing-related contraventions, unlawful discrimination and breaches of immigration law. The same test applies to any property manager.

What's the penalty for renting an unlicensed HMO?

Unlimited fine on conviction, plus the local authority can serve a civil penalty of up to £30,000. Tenants can also apply for a Rent Repayment Order to reclaim up to 12 months' rent. You also cannot serve a valid Section 21 notice while the HMO is unlicensed.

HMO Licence Application — Step-by-Step Guide for UK Landlords (2026)

📅 Updated May 2026 ⏱ 12 min read 🏷 Compliance

Houses in Multiple Occupation (HMOs) are one of the most regulated parts of the UK rental market. Get the licensing wrong and you face fines of up to £30,000, Rent Repayment Orders and an invalid Section 21 notice. This guide walks through who needs an HMO licence in 2026, the application process step by step, what councils actually look for, and how the rules vary between mandatory and additional licensing schemes.

Quick summary: A mandatory HMO licence is required for any property with 5+ unrelated tenants forming 2+ households who share amenities. Many councils have additional licensing covering smaller HMOs (3–4 person). Licences typically last 5 years, cost £500–£1,500, and require the landlord to pass a "fit and proper person" test.

What counts as an HMO?

An HMO is a property that meets both of these criteria:

It's occupied by 3 or more people forming 2 or more "households", AND
The occupants share basic amenities such as kitchen, bathroom or toilet

A "household" is typically a single person, a couple, or family members living together. Three flatmates who aren't related = three households.

Common examples of HMOs:

A student let with 4 unrelated students sharing kitchen and bathroom
A shared house with 5 young professionals on individual room tenancies
Bed-and-breakfast accommodation used as someone's main residence
Some hostels and shared housing

Not HMOs:

A family of 6 living together (one household)
A couple plus their adult child living together
A single tenancy with a couple sharing

The three types of HMO licensing

1. Mandatory HMO licensing

Applies across England and Wales. A licence is mandatory if a property is occupied by:

5 or more people forming 2 or more households, AND
They share kitchen, bathroom or toilet facilities

This applies regardless of the council you're in. Every local authority must license these properties.

2. Additional HMO licensing

Some local authorities designate additional HMO licensing schemes that cover smaller HMOs — typically 3 or 4 person properties. Councils with high HMO concentration (Newham, Liverpool, Nottingham, parts of Manchester, parts of London) frequently operate these. The threshold and rules vary by council.

3. Selective licensing

Separate from HMO licensing. Selective licensing covers all private rentals (not just HMOs) in a designated area where the council has identified housing market failure or anti-social behaviour. Many cities operate selective schemes covering specific wards or postcodes. A property may need a selective licence even if it's a single-let.

⚠ Watch out: Always check the council's specific licensing rules before letting any property. Schemes change frequently. Check both whether HMO additional licensing applies AND whether selective licensing covers the postcode.

Article 4 directions — planning vs licensing

Separately from licensing, some councils have Article 4 directions that remove permitted development rights — meaning converting a single dwelling (C3) into a small HMO (C4, 3–6 people) requires planning permission. Article 4 is about planning, not licensing. You can need both.

Common Article 4 areas: parts of Brighton, Nottingham, Reading, Birmingham, Leeds and Newcastle. Always check council planning portal before committing to an HMO conversion.

How much does an HMO licence cost?

Fees are set by each local authority and vary widely. Typical 2026 fees:

£500 – £900 — many shires and smaller cities
£800 – £1,500 — most major cities
£1,000 – £2,000+ — some London boroughs and licensing-heavy councils

Fees may be charged in two parts: an application fee and a "grant" fee (paid once the licence is approved). Some councils have surcharges per habitable room. Always check the specific fee schedule with your local authority — it changes between budgets.

What an HMO licence actually requires

To grant a licence, the council needs to be satisfied that:

1. The licence holder is fit and proper

The council checks the landlord (and any property manager) for:

Past convictions — especially fraud, violence, sexual offences, drug offences
Housing-related contraventions (illegal evictions, harassment, unlicensed HMOs elsewhere)
Breaches of immigration law
Unlawful discrimination (Equality Act)

2. The property is suitable

Including:

Minimum room sizes (see below)
Adequate kitchen and bathroom facilities for the number of occupants
Fire safety: smoke alarms, fire doors (FD30 in many councils), emergency lighting in larger HMOs
Gas, electric and energy safety certificates in place
Means of escape (often a protected staircase)

3. Adequate management arrangements

The council wants to see who manages the property day-to-day. Some councils require demonstrable knowledge or qualifications (e.g. NRLA accreditation) — others accept self-declaration.

Minimum room sizes (mandatory licensed HMOs in England)

The Licensing of Houses in Multiple Occupation (Mandatory Conditions of Licences) (England) Regulations 2018 set national minimums:

Sleeping use	Minimum floor area
One person aged over 10	6.51 m²
Two people aged over 10	10.22 m²
One child aged under 10	4.64 m²

Areas with floor-to-ceiling height under 1.5m don't count towards the floor area. Bathrooms, kitchens, hallways and other communal space are excluded — only sleeping accommodation counts.

Many councils impose higher local minimums (e.g. 9m² for one adult). Always check both the national rule and the local council's HMO standards.

Step-by-step application process

Check if you need a licence. Use the council's online checker or call the licensing team. Verify mandatory + additional + selective + Article 4 all in one go.
Prepare the property. Bring it up to HMO standards before applying — councils often visit and any deficiencies will delay or invalidate the application.
Get safety certificates. Gas Safety Certificate, EICR, EPC, fire alarm test certificate, emergency lighting (if applicable), portable appliance test certificates if appliances supplied.
Measure every room. Floor plans with all dimensions are required by most councils. A scaled floor plan from a recent surveyor's report works.
Complete the application form. Online via council portal in most areas. Be precise about occupancy numbers, room uses and amenities.
Notify "relevant persons". You must notify the freeholder, mortgage lender, any leaseholder and the tenant(s) that you've applied. Get acknowledgements.
Pay the fee. Some councils split into application + grant fees.
Wait for council inspection. Most councils visit within 3 months. They'll check room sizes, fire safety, amenities and management arrangements.
Address any conditions. The licence is typically issued with conditions — fire upgrades, room amendments, etc. — that you must complete within a stated time.
Display the licence. Keep a copy at the property and provide one to tenants.

Typical timeline

From application to licence in hand:

Best case: 6–8 weeks (clean application, no inspection issues)
Typical: 3–6 months
Worst case: 9–12 months for complex properties or councils with backlogs

✓ OwnProperly tip: Apply for renewal at least 90 days before expiry. The application itself extends your current licence by deemed-grant in most councils, but you need to be in the queue.

Penalties for unlicensed HMOs

Civil penalty up to £30,000 per breach (in lieu of prosecution)
Unlimited fine on conviction
Rent Repayment Order — tenants can claim back up to 12 months' rent
Banning Order in serious cases — preventing you from being a landlord
Invalid Section 21 notice — you cannot evict on no-fault grounds while unlicensed
Mortgage default risk — lenders typically require properties to be properly licensed

Rent Repayment Orders are particularly painful. A landlord with a £600/room HMO of 5 rooms unlicensed for 12 months can be ordered to pay back up to £36,000 to tenants — often substantially more than the licence fee they "saved".

HMO compliance checklist

Renewing an HMO licence

Most HMO licences last 5 years. To renew:

Apply at least 90 days before expiry — most councils have an online portal
Confirm any changes in occupancy, layout or management since the original grant
Provide up-to-date safety certificates
Pay the renewal fee (often slightly less than initial)
Councils may re-inspect, especially if there have been complaints during the previous term
