1. Overview
A House in Multiple Occupation (HMO) licence is required when a rental property is occupied by a certain number of people from multiple households who share facilities such as bathrooms, kitchens, or toilets. The mandatory HMO licensing scheme, which applies across England and Wales, requires a licence for properties occupied by five or more people forming two or more separate households. Since October 2018, this applies regardless of the number of storeys — previously, only properties of three or more storeys needed mandatory licensing.
Beyond the mandatory national scheme, local authorities have discretionary powers to introduce additional licensing (covering smaller HMOs in designated areas) and selective licensing (covering all private rented properties in designated areas, regardless of whether they are HMOs). This means a standard single-let property could require a selective licence depending on where it is located. Landlords must check with their specific local authority, as schemes vary dramatically — some councils have borough-wide selective licensing, while others have no additional schemes at all.
An HMO licence typically lasts five years and comes with conditions that the landlord must meet throughout the licence period. These conditions commonly include: maximum occupancy numbers, provision of adequate kitchen and bathroom facilities (ratios vary but typically one bathroom per four to five occupants), fire safety measures (fire doors, fire blankets, extinguishers, emergency lighting), annual gas safety certificates, valid EICRs, adequate waste disposal arrangements, and management standards for common areas. Operating an unlicensed HMO is a criminal offence carrying an unlimited fine, and tenants can apply for a Rent Repayment Order to reclaim up to 12 months' rent.
2. Cost
A HMO Licence typically costs between £500 and £1500. Fees vary enormously by council. Mandatory HMO licence fees range from £500 to £1,500 for a 5-year licence. Some councils charge per room or per occupant. Selective licence fees are typically lower (£400–£800). Renewal fees are usually 60–80% of the initial application fee. Many councils charge a higher fee for late applications.
3. Regional Variations
England
Mandatory HMO licensing applies to properties with 5+ occupants from 2+ households since October 2018 (any number of storeys). Councils can introduce additional licensing for smaller HMOs and selective licensing for all PRS properties. Over 60 councils operate selective licensing schemes. Rent Repayment Orders allow tenants to reclaim up to 12 months' rent from unlicensed HMO landlords.
Wales
Mandatory HMO licensing in Wales mirrors England (5+ people, 2+ households). However, all landlords in Wales must also register with Rent Smart Wales, which is separate from HMO licensing. Additional and selective licensing schemes can be introduced by Welsh local authorities. The Renting Homes (Wales) Act 2016 adds further requirements around occupation contracts.
Scotland
Scotland has its own HMO licensing regime under the Civic Government (Scotland) Act 1982, as amended by the Housing (Scotland) Act 2006. An HMO in Scotland is defined as any property occupied by three or more people from two or more families — a lower threshold than England. All HMOs require a licence from the local authority, typically lasting 1–3 years (shorter than England's 5 years). Scotland does not have selective licensing.
Northern Ireland
HMO licensing in Northern Ireland is governed by the Houses in Multiple Occupation Act (Northern Ireland) 2016. An HMO is defined as a property occupied by three or more people from two or more households. All HMOs must be registered and licensed with the local council. Northern Ireland does not have selective licensing. The Northern Ireland Housing Executive provides guidance on HMO standards.

How do I know if my property is an HMO?
A property is an HMO if it is occupied by 3 or more people forming 2 or more separate households who share a kitchen, bathroom, or toilet. A 'household' is typically a family unit or a couple — unrelated sharers each form their own household. So a house shared by 3 unrelated professionals is an HMO (3 people, 3 households). A couple and one other person is also an HMO (3 people, 2 households). Mandatory licensing kicks in at 5+ people from 2+ households in England.
What is a Rent Repayment Order and how does it affect me?
A Rent Repayment Order (RRO) allows tenants or the local authority to apply to the First-tier Tribunal to reclaim up to 12 months' rent paid while a property was operated as an unlicensed HMO. Tenants can apply directly without council involvement. If successful, the landlord must repay the rent — this is in addition to any criminal fine. RROs are a powerful incentive to ensure licensing is in place before tenants move in.
What happens if I apply late for an HMO licence?
Most councils charge a higher fee for late applications (sometimes double the standard fee). You are technically committing a criminal offence for every day you operate without a licence, so the council could prosecute. However, most councils prefer to bring landlords into compliance rather than prosecute, provided you apply promptly once aware. Do not wait for the council to contact you — proactive applications are viewed much more favourably.
Can I convert a single-let property into an HMO?
Possibly, but you may need planning permission. Under the Use Classes Order, a property occupied by up to 6 unrelated people is Class C4 (small HMO), and anything larger is sui generis. Many councils have introduced Article 4 Directions removing permitted development rights for C3 to C4 conversions, meaning you need planning permission. You will also need to meet HMO standards for fire safety, room sizes (minimum 6.51 sqm for a single room), and facility ratios.
Does selective licensing apply to my property?
Check your local authority's website or call their private sector housing team. Selective licensing applies to all private rented properties (not just HMOs) in designated areas. Schemes must be approved by the Secretary of State if they cover more than 20% of a borough's PRS. Common triggers for selective licensing include high levels of anti-social behaviour, poor property conditions, deprivation, or high migration areas. The licence conditions are usually less onerous than HMO licence conditions.
