HMO licence: what it means and when you need one
Published · Updated
An HMO licence is a council licence to rent out a house in multiple occupation. In England and Wales you must have one for a large HMO, meaning a property rented to 5 or more people who form more than one household, where some or all tenants share a toilet, bathroom or kitchen, and at least one pays rent [1]. Councils can also require licences for smaller HMOs in their area, so always check with yours [1]. A licence lasts up to 5 years, the fee is set by the council, and renting out an unlicensed HMO can mean an unlimited fine [1].
HMO licence meaning: what is an HMO?
GOV.UK defines a house in multiple occupation (HMO) as a property rented out by at least 3 people who are not from one "household" (for example, a family) but share facilities like the bathroom and kitchen [1]. It's often called a house share.
So three friends sharing a house and a kitchen is an HMO. A couple with their child isn't, because they're one household.
Do I need an HMO licence?
There are three routes to needing one:
| Type | When it applies | Source |
|---|---|---|
| Mandatory HMO licensing | A large HMO: 5 or more people, more than 1 household, shared toilet, bathroom or kitchen, at least 1 paying rent | Applies across England and Wales [1] |
| Additional licensing | Smaller HMOs, where the council has an additional licensing scheme | Council-specific [1] |
| Selective licensing | Most private lets in a designated area, HMO or not | Council-specific |
GOV.UK's advice is straightforward: if you want to rent out a property as an HMO, "you must contact your council to check if you need a licence", because even smaller HMOs may need one depending on the area [1].
HMO licence check: how to find out
- Use GOV.UK's HMO licence page and enter your postcode to find your council [1].
- Read your council's licensing pages. Look for "additional licensing" and "selective licensing" as well as mandatory HMO licensing.
- Check the public register. Councils keep a register of licensed HMOs, which is also how tenants check a property is licensed.
- Ask the council if you're unsure whether your property counts.
HMO licence requirements and conditions
GOV.UK lists what you must make sure of when you hold an HMO licence [1]:
- the house is suitable for the number of occupants, depending on its size and facilities
- the manager, you or an agent, is "fit and proper", for example with no criminal record or breach of landlord laws or code of practice
And what you must also do [1]:
- send the council an updated gas safety certificate every year
- install and maintain smoke alarms
- provide safety certificates for all electrical appliances when requested
The council may add other conditions, for example improving facilities, and will tell you when you apply. If you disagree with conditions, you can appeal to the First-tier Tribunal [1].
Beyond the licence, HMOs have their own management rules and fire safety expectations, and every rented home still needs a valid EICR, an EPC at band E or above, and smoke and carbon monoxide alarms where required. See our guides to EICR certificate cost and smoke and CO alarms.
HMO licence cost
The fee is set by your council [1], so there's no national price. Fees vary widely between councils and can depend on the number of rooms or occupants and whether you apply early or are renewing. See our separate guide to HMO licence fees for how to find your council's current charges.
How long does an HMO licence last?
A licence is valid for a maximum of 5 years, you must renew it before it runs out, and you need a separate licence for each HMO [1]. Councils can grant shorter licences.
How to apply for an HMO licence
- Find your council through GOV.UK [1].
- Gather documents. Typically a floor plan, gas safety certificate, EICR, fire safety details and evidence about the manager. Your council's form will list what it needs.
- Apply yourself. GOV.UK says you should apply yourself, though a managing agent can apply for you [1].
- Pay the fee set by the council [1].
- Expect an inspection and possibly conditions.
- Diary the expiry. Set a reminder well ahead of the end date.
HMO licence fines and penalties
GOV.UK says you could get an unlimited fine for renting out an unlicensed HMO [1]. Councils can also use other enforcement powers, and tenants in unlicensed properties may be able to apply for rent repayment orders, which the Renters' Rights Act expanded [2].
Managing an HMO without an agent
HMOs mean more tenants, more repair reports and more certificates. The annual gas safety certificate goes to the council as well as your tenants [1], so a missed renewal is a licence breach as well as a safety one.
Gaffy gives each HMO one repair link for the property: any tenant can report a problem from their phone's browser, with photos, and it lands in one inbox against that property. The document vault holds the licence, gas safety certificate, EICR and EPC, and flags gas safety, EICR and EPC expiry dates before they pass. See the document vault and gas safety certificate reminders.
Selective licensing
Some councils run selective licensing schemes that cover most private lets in a designated area, whether they're HMOs or not. If your property is in one, you'll need a licence even for a single family let. Check your council's pages.
Before you apply
Check room sizes and facilities against your council's standards, make sure fire safety measures are in place, and have current gas and electrical certificates ready. Applications go faster when the paperwork is complete.
If you inherited an HMO, read HMO licence when the licence holder dies.
