HMO Licence UK: Do You Need One and How to Get It (2026 Guide)

If you let a property to multiple tenants who are not all from the same household, you could be operating a House in Multiple Occupation — and that comes with significant legal responsibilities. An HMO licence is not optional for those who meet the threshold: it is a legal requirement under the Housing Act 2004, and getting it wrong can cost you far more than the licence fee.

This guide explains what qualifies as an HMO, when a licence is required, how to apply, and what happens if you do not comply.

What Is an HMO? The Legal Definition

Under Part 2 of the Housing Act 2004, HMO status turns on a set of tests in section 254, and none of them counts heads. A building or part of a building is an HMO if it meets any one of:

• The standard test (s.254(2)) — it is not a self-contained flat, it is occupied by people in two or more separate households as their only or main residence, and they share basic amenities such as a kitchen, bathroom or toilet, or the property lacks them
• The self-contained flat test (s.254(3)) — a self-contained flat, otherwise on the same terms
• The converted building test (s.254(4)) — a converted building containing accommodation that is not entirely self-contained flats
• A declaration (s.255) — the local housing authority declares the property to be an HMO
• A converted block of flats (s.257) — a separate category, covered below

There is no minimum number of occupants in the definition. A two-person, two-household property can be an HMO. The "three or more people" figure repeated across most landlord guidance is a licensing threshold from an order that was revoked in 2018 — it was never the definition, and it is not the current threshold either. The number that matters for mandatory licensing today is five, and that is a licensing question, not a definition question.

A "household" is a question of relationship, not of paperwork. Section 258 works by exclusion: people are not a single household unless all of them are members of the same family — a couple, or a relative of the other, where relative means parent, grandparent, child, grandchild, brother, sister, uncle, aunt, nephew, niece or cousin. So two couples and a single person sharing a house are three households. And because it turns on relationship, four unrelated sharers on a single joint tenancy are still four households — signing one agreement instead of four does not change the answer.

Common examples include:

• Student houses where each tenant has their own room and shares a kitchen
• Bedsit-style properties where individual rooms are let separately
• Large shared houses let to young professionals
• Converted properties with self-contained bedsits that share a hallway

A converted block of flats is treated separately under s.257: it is an HMO only where the conversion did not comply with the building standards applicable at the time and still does not, and fewer than two-thirds of the flats are owner-occupied.

The exclusions are listed in Schedule 14 and include buildings controlled or managed by a public body, certain student accommodation, religious communities, and owner-occupied buildings within the limits set by paragraph 6. Read the paragraph that covers your situation rather than a summary of it — the owner-occupier exclusion in particular is narrower than it is usually reported to be.

How you let the property is a separate question from whether it is an HMO: one joint agreement or a separate agreement for each room, the tests above are the same. What changes with separate agreements is the paperwork — see deposits, rent and notice when you let by the room.

Mandatory, Additional and Selective Licensing

Being an HMO and needing a licence are two different questions. Not every HMO requires a licence, and — as below — not every licence is about HMOs at all. There are three separate schemes, and they are not mutually exclusive.

Mandatory licensing is set by SI 2018/221, in force since 1 October 2018. Article 4 prescribes an HMO for licensing where all three apply: it is occupied by five or more persons; they live in two or more separate households; and it meets the s.254(2) standard test, the s.254(3) self-contained flat test (excluding a flat in a purpose-built block of three or more self-contained flats), or the s.254(4) converted building test.

The three-storey rule is gone. Article 6 of that order revoked SI 2006/371, which is where the storey requirement lived. It has not applied to anything since 1 October 2018, and storey count is now irrelevant to mandatory licensing. You can read the government guidance at gov.uk/house-in-multiple-occupation-licence.

Additional licensing (s.56) is a discretionary scheme a council can designate so that other HMOs in an area need a licence — for example, smaller shared houses below the five-person mandatory threshold. A designation can cover all HMOs in the area.

Selective licensing (s.80) is not an HMO scheme at all. It licenses privately rented houses in a designated area, and it is not limited to HMOs, where the area has low housing demand or a significant and persistent anti-social behaviour problem. A landlord letting a three-bedroom house to one family can need a selective licence and can never need an HMO licence. Collapsing these two is the single most common mistake in this area. (The two do not stack: a house that is an HMO needing a mandatory or additional licence is licensed under that scheme, not the selective one — s.85(1)(a).)

Note that SI 2018/221 applies to England only; Wales operates its own licensing regime. There is no national register of designations and no lookup that will tell you whether your street is covered — the council decides, and the only correct answer is to ask them. The gov.uk page above carries a postcode-to-council lookup. Do not assume that falling below the five-person threshold means no licence is needed.

For how the three schemes fit together, and when a house let to one family can need a licence, see additional and selective licensing compared.

Applying for an HMO Licence

Applications are made to the local housing authority where the property is located. The process typically involves:

1. Completing the council's application form (most councils now offer online applications)
2. Paying the application fee, which varies by council — commonly between £500 and £1,500 for a five-year licence
3. Submitting supporting documentation: gas safety certificate, electrical installation condition report (EICR), energy performance certificate, and a floor plan of the property
4. Demonstrating that you (and any managing agent) are a "fit and proper person" — this means no relevant criminal convictions, no history of housing offences, and no prior banning orders

The council will inspect the property before granting a licence to confirm it meets HMO management standards. A licence is typically valid for five years, after which it must be renewed. HMO landlords must also carry out a Right to Rent check on every adult occupant — not just the lead tenant — before they move in, and set follow-up reminders for anyone with time-limited leave to remain.

Keeping on top of all these compliance requirements is easier when you have a single place to track document expiry dates. LetSorted's compliance dashboard (see landlord compliance checklist) keeps your certificates organised and flags upcoming renewals so nothing lapses.

HMO Licence Conditions

A licence is not simply a certificate of approval — it comes with conditions attached. Common conditions include:

• Maximum occupancy — the licence specifies the maximum number of occupants permitted
• Room size standards — a licence must require minimum sleeping-room floor areas under Schedule 4, paragraph 1A: 6.51 m² for one person over 10, 10.22 m² for two people over 10, and 4.64 m² for one person under 10. A room below 4.64 m² must not be used for sleeping at all. These are licence conditions, so they bite on a licensed HMO — they are not free-standing offences that apply to every shared house
• Amenities — sufficient kitchen facilities, bathrooms, and WCs must be provided for the number of occupants
• Gas and electrical safety — annual gas safety certificates and five-yearly EICRs must be maintained (remember there is no grace period if your gas safety certificate expires, and a late inspection cannot be backdated to cover the gap)
• Fire safety — councils commonly attach conditions covering alarms, detection and fire doors. The specifications are set by your council's own licensing standards, not by a national table (see below)

Breaching any condition is a separate offence from operating without a licence and can result in a civil penalty of up to £40,000 per breach under section 249A of the Housing Act 2004 — raised from £30,000 on 1 May 2026. The council may also revoke the licence entirely. Correct as at 22 September 2026.

Licence conditions also constrain what you can agree to mid-tenancy. A shared property with several cars is where tenants most often ask about charge points, and the electrical load, the parking provision and the licensing conditions all have to be checked before you say yes — see EV charging points in rental properties.

The room sizes, how floor area is measured under a sloping ceiling, and the 18-month period to fix a room that falls short are covered in HMO room sizes and the other licence conditions.

Fire Safety in HMOs

HMOs carry a higher fire risk than single-household properties because multiple occupants may be asleep at different times, and shared corridors can fill with smoke quickly.

The binding duty is regulation 4 of the Management of Houses in Multiple Occupation (England) Regulations 2006, which requires the manager to ensure that:

• All means of escape from fire are kept free from obstruction and maintained in good order and repair
• Any firefighting equipment and fire alarms are kept in good working order
• Notices indicating the location of each means of escape are displayed so they are clearly visible to occupiers — not required where the HMO is occupied by four or fewer people
• All reasonable measures are taken to protect occupiers from injury, having regard to the design of the property, its structural condition and the number of occupiers
• Unsafe roofs and balconies, and windows with low sills, are made safe or access to them restricted

Regulation 4 is written as an outcome, not a specification. It does not name a fire door rating, an alarm grade or a number of extinguishers, and neither does any other instrument. The "30-minute fire doors with self-closers" standard quoted throughout landlord guidance comes from LACORS guidance — issued by a local-government body that no longer exists. It is guidance, not law, and it is not the same thing in every area. Your council's licensing standards are what actually set the specifications, so ask them what they require before spending money against a figure from a blog.

These regulations do not apply to a converted block of flats falling under s.257 — that category is carved out of regulation 1.

Your local council's housing officer will inspect fire safety provisions as part of the licensing process and may require additional measures depending on the layout.

Regulation 4 is one of eight duties on the manager. Water, gas and electrics, the shared areas, each occupier's room and waste are set out in the manager's duties under the 2006 regulations.

Penalties for Non-Compliance

The consequences of operating an unlicensed HMO are severe, and every figure below changed on 1 May 2026. Under section 72 of the Housing Act 2004, controlling or managing an HMO that is required to be licensed and is not is a criminal offence. Penalties include:

• Unlimited fines in the magistrates' court. The offence carries a fine at level 5 on the standard scale, and level 5 has been unlimited since 12 March 2015, when s.85 of the Legal Aid, Sentencing and Punishment of Offenders Act 2012 removed the cap. That was not the Housing and Planning Act 2016, and the change is a decade old
• Civil penalties of up to £40,000 per offence under section 249A of the Housing Act 2004 — raised from £30,000 on 1 May 2026. This is an alternative to prosecution, not an addition to it
• Banning orders preventing you from letting properties or managing them
• Rent Repayment Orders — tenants or the local authority can apply for repayment of up to 24 months of rent paid during the period of non-compliance, under s.44 of the Housing and Planning Act 2016 as amended on 1 May 2026. The old figure was 12 months; it doubled (see our guide to rent repayment orders and how landlords can avoid them)

Correct as at 22 September 2026. These figures have moved once already this year — check them before relying on them.

Two changes on 1 May 2026 widened who is exposed. Section 72(1)(b) now catches a superior landlord, not only the person having control of or managing the property, and s.40(1) of the 2016 Act extends Rent Repayment Orders to a superior landlord in the same way. Letting through an intermediary is no longer a way to sit outside the offence. Section 72(4C) also confirms that a term in the tenancy agreement is not, by itself, a defence.

Older guidance adds a further sanction: that an unlicensed HMO landlord was barred from the no-fault possession route while the breach continued. Section 21 was abolished on 1 May 2026, so that route no longer exists for any landlord, licensed or not, and the sanction has nothing left to bite on. Do not read that as good news — it removed the one consequence landlords tended to actually notice, while the offence behind it got wider and the money got larger. Reviewing the full range of penalties in our landlord fines guide is strongly recommended for any landlord managing an HMO.

Note also that HMOs must meet minimum EPC standards just like other rental properties — check what is currently required in our EPC rating guide for landlords.

Frequently Asked Questions

When does a property need a mandatory HMO licence in England?

A mandatory HMO licence is required in England where the property is occupied by five or more people forming two or more separate households, and it meets one of the Housing Act 2004 section 254 tests — most commonly a shared house where tenants share a kitchen, bathroom or toilet. There is no storey requirement: the old three-storey rule was revoked on 1 October 2018. Your council may also operate an additional or selective licensing scheme covering smaller properties, so check with them. Correct as at 22 September 2026.

How much does an HMO licence cost in the UK?

HMO licence fees vary by local council and typically range from £500 to £1,500 or more for a five-year licence. Some councils charge in two stages: an application fee and a grant fee paid only if the licence is approved. A licence lasts a maximum of five years.

What happens if I rent out an HMO without a licence?

Operating an unlicensed HMO is a criminal offence under section 72 of the Housing Act 2004. You face an unlimited fine on conviction, or a civil penalty of up to £40,000 as an alternative to prosecution, plus a possible banning order. Tenants or the council can also apply for a Rent Repayment Order covering up to 24 months of rent. Since 1 May 2026 the offence catches a superior landlord as well as the person managing the property. Correct as at 22 September 2026.

Conclusion

Running an HMO without the required licence is one of the most costly mistakes a landlord can make. Unlimited fines, a £40,000 civil penalty and Rent Repayment Orders of up to two years' rent combine to create a risk that far outweighs the inconvenience of applying. If your property houses five or more people from two or more households, contact your local council's housing team today and begin the application process — and if it houses fewer, ask them anyway, because additional and selective licensing are theirs to designate and nothing but asking will tell you.

If you want to manage your compliance documents, certificate renewals, and property records in one place, LetSorted's property management tools are built specifically for self-managing UK landlords. For an HMO, LetSorted can also track each room separately: its own tenancy, rent and deposit deadline, with the licence and the building's checks kept once.
