HMO licensing in 2026: does your rental property need a licence?

Updated July 2026 · Applies to England · 6 minute read

If you let a shared house or a converted flat to unrelated tenants, you may need a licence before you can legally operate it. The rules that decide whether a property is a house in multiple occupation (HMO) have not changed under the Renters' Rights Act, but the cost of getting them wrong has gone up sharply since 1 May 2026. Operating an unlicensed HMO can now mean a civil penalty of up to £40,000, on top of a rent repayment order worth up to two years' rent. This guide sets out what counts as an HMO, which licence applies to you, the national minimum standards every licensed HMO must meet, and what happens if you skip it.

What counts as an HMO

A property is an HMO if at least 3 tenants live there, forming more than 1 household, and they share a toilet, bathroom or kitchen. A household means a single person, or people who are married, in a relationship, or related to each other. Two friends sharing a 2-bed flat are not an HMO at all - you need at least 3 tenants forming more than 1 household before the rules even apply.

A large HMO is one where at least 5 tenants live there, again forming more than 1 household and sharing facilities. This is the threshold that triggers mandatory, nationwide licensing.

Three types of licensing - and why the label matters

• Mandatory licensing. Applies automatically across all of England to every large HMO (5 or more tenants, 2 or more households, shared facilities), regardless of how many storeys the building has - the old three-storey rule was removed in October 2018.
• Additional licensing. A discretionary scheme individual councils can introduce under the Housing Act 2004 to catch smaller HMOs, typically 3 or 4 occupants, across their whole borough or specific wards. Over 70 councils in England already run one, and more areas are being added - Havering and Reading, for example, both bring in new additional schemes from March 2026.
• Selective licensing. A separate scheme again, which can require a licence for any rented property in a designated area - HMO or not - usually where a council has concerns about property conditions or antisocial behaviour.

Because additional and selective schemes vary street by street and change over time, "I'm under 5 tenants" is not the same as "I'm licence-free". Always check your own postcode on your local council's website before assuming you're exempt.

The national minimum standards

Since October 2018, every mandatory HMO licence carries fixed national conditions that no council can lower. The best known are the minimum floor areas for rooms used as sleeping accommodation.

Ceiling height matters too - any part of a room with a ceiling lower than 1.5 metres does not count towards the floor area, which catches out attic and loft conversions in particular. On top of room sizes, the licence holder and the manager of the property must pass a "fit and proper person" test (no relevant criminal record or history of breaching landlord law), and a licence normally runs for up to 5 years.

How to apply

1. Apply to your local council, not to a national body - the fee is set locally and varies significantly between areas.
2. A managing agent can apply on your behalf if you use one.
3. Expect to provide floor plans, a current gas safety certificate, an electrical safety report (EICR), and details of fire precautions such as smoke alarms and fire doors.
4. The council will assess the property against the national conditions plus any local ones, and check the fit and proper person test before issuing the licence.

What happens if you don't get one

Operating an HMO that should be licensed, without a licence, is a criminal offence. Councils can prosecute for an unlimited fine, or issue a civil penalty instead - and since the Renters' Rights Act took effect on 1 May 2026, that civil penalty cap rose from £30,000 to £40,000.

Separately, tenants (or the council) can apply to the First-tier Tribunal for a rent repayment order to claw back rent already paid. For offences committed on or after 1 May 2026, tenants can now recover up to 24 months' rent, up from 12 months previously, and the window to bring the claim has also been extended from 12 to 24 months after the offence. An unlicensed HMO also weakens your position generally - it is hard to look like a compliant landlord in front of a court if you are relying on a Section 8 ground for possession while the property itself is unlicensed.

Frequently asked questions

Do I need an HMO licence for a 2-bed flat shared by two friends? No. You need at least 3 tenants forming more than 1 household before a property counts as an HMO at all, so a 2-person flat share is outside the rules entirely.

My property only has 4 tenants - am I safe? Not automatically. Mandatory licensing only catches 5 or more tenants nationwide, but many councils run additional licensing that pulls in 3 to 4 tenant HMOs. Check your council's page for your exact postcode.

How long does an HMO licence last? Normally up to 5 years, and it does not transfer if you sell - the new owner has to apply for their own licence.

What if I buy a property that's already an unlicensed HMO? You become responsible for it from the day you take over. Apply before you let it or continue letting it - a prompt, properly made application can also provide a defence if the position is later queried.
