Understand Mandatory Licensing for HMO Properties

Understand Mandatory Licensing for HMO Properties in North London: A Landlord’s Guide

Understand Mandatory Licensing for HMO Properties in North London by checking who lives in the property, how many households they form and which facilities they share. We advise landlords to check the national test and the exact borough requirements before letting, because one licence does not automatically meet every local or property safety duty.

Key Takeaways

• First decide whether the occupants and shared facilities make the property a House in Multiple Occupation (HMO). The building’s layout alone does not settle the question.
• Mandatory HMO licensing is based on the occupants and household arrangements, not simply the number of storeys or tenancy agreements.
• Use the council responsible for the property’s exact address to check for additional or selective licensing as well as mandatory licensing.
• Purpose-built flats and converted buildings need property-specific checks.
• A licence may set conditions for occupancy, management and property standards. Safety duties and maintenance continue after it is granted.
• For a practical overview of North London requirements, read our guide to mandatory HMO licensing for North London landlords.

When a rental property counts as an HMO

A rental property will generally count as an HMO when at least three people live there as their only or main home, form at least two households and share facilities such as a kitchen, bathroom or toilet. This describes the HMO classification; it does not, by itself, mean that mandatory licensing applies.

A household is usually made up of one person or members of the same family living together. People who are married, living together as a couple or related in specified ways are generally treated as one household, while unrelated sharers can form separate households at the same address.

Assess who actually occupies the property and how they use its facilities. A tenancy agreement can help document the arrangement, but the number of agreements, the number of storeys and the layout do not establish HMO status on their own.

Where the household position is not straightforward, record the occupants’ relationships and living arrangements. We recommend making this assessment before agreeing a letting, since the licensing decision depends on the actual use of the property.

The national mandatory licensing test

For mandatory HMO licensing in England, assess the number of residents, how many separate households they form and whether they share facilities. The national threshold is summarised below.

In England, HMOs with 5 or more people in 2 or more separate households will in many cases require a licence.

Do not use the number of storeys as the deciding test. The Ministry of Housing, Communities and Local Government says mandatory licensing came into force in 2006 and originally applied to properties of three storeys or more with five or more people in two or more separate households; the current test is not limited to properties of that height.

Some statutory exceptions and property-specific circumstances can affect the result. Treat the occupancy test as the starting point, then consider the building type, management arrangements and any relevant exemption before deciding whether a licence is required.

Check the exact address against borough licensing schemes

Start by identifying which borough contains the property, then use that council’s current licensing map or address search. This is the practical way to find out whether an additional or selective licensing designation covers the exact address.

A smaller HMO may need an additional licence even when the mandatory test does not apply. Selective licensing is different: it can cover other privately rented properties within a designated area, including properties that are not HMOs.

North London boroughs, including Barnet, Haringey and Islington, administer their own licensing requirements and fee arrangements; the applicable rules depend on the property’s borough.

There is no single North London licensing boundary: schemes are designated by individual councils and may cover only specified areas or property types. For Barnet, Haringey, Islington or Camden, check the council’s current licensing pages using the full address, including the flat number where relevant. Check the scheme map as well as any address-search result, and confirm that the designation covers the property and the type of letting proposed. Keep a copy of the result and, if the address or scheme coverage is unclear, ask the council’s licensing team to confirm in writing. A borough name or postcode alone is not enough to establish whether a licence is required.

Assess mandatory, additional and selective licensing separately. If more than one scheme appears relevant, give the council the property details and ask how the requirements apply together.

Purpose-built flats and converted buildings need closer checks

A purpose-built flat is not automatically exempt from HMO licensing. Any exemption depends on the statutory criteria and the specific building and management arrangements, so the label purpose-built is not enough to reach a decision.

A converted building’s conversion history and present condition can matter when assessing its licensing requirements. Its conversion history and present condition can therefore matter as much as the way it is occupied.

If an exemption is uncertain, give the council the property-specific facts and ask for its decision. Do not rely on the building’s age, number of storeys or appearance alone.

What councils consider in an application

Prepare information about ownership, the proposed manager, who will occupy the property and how it will be managed. Councils may also ask for a floor plan and relevant safety records, but the responsible council sets the exact application requirements.

The council can assess whether the proposed manager is a fit and proper person and whether the property is suitable for its intended use and number of occupants. Be ready to explain how the layout, facilities and management arrangements support the proposed occupancy.

A licence may set conditions covering the maximum occupancy, management practices and property standards. Read each condition carefully and follow it throughout the licence period, not only while the application is being considered.

The responsible council handles the application and fee, and both can vary locally. Keep a clear record of the grant date and expiry date, and start renewal arrangements in good time to avoid a lapse in licensing.

Camden application checklist

For a property in Camden, use the council’s current application requirements and fee schedule rather than relying on a generic form or a fee quoted for another borough. Confirm which licence route applies to the address, the total fee and when payments are due. Before applying, have the ownership and proposed licence-holder and manager details, a room-by-room occupancy schedule, and a floor plan showing room dimensions and shared facilities ready. Check Camden’s current list to see which safety records or other documents must accompany the application, and ensure the details match the proposed letting.

Safety duties continue after the application

Plan fire precautions around the property’s layout and risk. Suitable alarms, clear escape routes and any fire doors or emergency lighting required by the council’s assessment or licence conditions must be addressed as part of managing the HMO safely.

Keep gas safety checks current where gas appliances are present, and maintain the relevant electrical safety records. Repair hazards promptly; a licence is not a substitute for ongoing maintenance or compliance with other landlord duties.

The council may assess hazards under the Housing Health and Safety Rating System (HHSRS). GOV.UK states that the council has to carry out an HHSRS risk assessment on your HMO within 5 years of receiving a licence application.

Check the council’s property and amenity standards for the specific HMO, because required facilities and their suitability depend on factors such as occupancy and the property itself. Our landlord information also sets out key rental compliance records, including a current Gas Safety Certificate where gas appliances are present, an Energy Performance Certificate (EPC) and an electrical safety certificate (EICR).

Licensing is separate from planning and other compliance

An HMO licence does not grant planning permission or confirm that building regulations have been met. Check planning requirements separately, including whether a planning restriction or Article 4 direction affects the intended use of the property.

A licence applies to the property covered by that application; it does not cover a landlord’s other HMOs. Assess the requirements for each address separately and keep evidence of applications, safety work and compliance with licence conditions so you can respond promptly if the council raises an issue.

Operating without a required licence can lead to enforcement action. The House of Commons Library states that local authorities in England can impose civil penalties of up to £30,000 as an alternative to prosecuting landlords. Depending on the circumstances, a tenant or local authority may also apply for a rent repayment order, and prosecution is another possible outcome. The relevant route and outcome depend on the offence and evidence.

Do not be tempted to treat an application, a planning decision or a safety certificate as a replacement for the other requirements. Good practice is to keep a property-by-property compliance file and check each obligation on its own terms.

Frequently Asked Questions

Does an HMO licence transfer to a new owner when the property is sold?

The incoming owner should contact the council before completion to establish what application or interim arrangements it requires for the change of ownership.

What should a landlord do if the number of occupants or household arrangements change after a licence is granted?

Compare the proposed arrangement with the occupancy and household details recorded on the licence, then contact the council before implementing a change that could affect its terms. Keep written confirmation of any variation or further application the council requires.

Can a property still be an HMO when one of its rooms is temporarily vacant?

Yes, a temporary vacancy can leave the property’s overall use and the household arrangements of the people who remain unchanged. The reason for the vacancy and whether the room remains part of the shared letting can be relevant to the council’s assessment.

Can a landlord apply for an HMO licence before the intended tenants have moved in?

A landlord can approach the council about an application based on the proposed occupancy and management arrangements. Provide the intended details accurately, because the council’s decision and any licence conditions will relate to the property’s use.

Who is responsible for applying if a letting agent manages the property?

Using a letting agent does not, by itself, remove the landlord’s responsibility to make sure the property is properly licensed. Agree who will prepare and submit the application, who will communicate with the council and who will monitor licence conditions.

Relationships

To understand mandatory licensing for HMO properties in North London, begin with the actual occupants, their household relationships and the facilities they share. Then check the national test, the council’s address-specific schemes and any building-specific issues before the property is let.

Keep licensing, planning, building regulations and safety duties separate in your records, and follow every licence condition throughout the term. We advise landlords to deal with uncertainty directly with the responsible council, because careful checks are good practice and help protect the property as a business venture.
