A licensing problem often comes to light at the worst possible time: when a landlord is about to let a property, renew finance, sell, or respond to a council enquiry. This guide to landlord licensing rules sets out what London landlords need to check before tenants move in, and why the answer can change from one borough – or even one street – to the next.
Licensing is not simply another form to file away. Operating a licensable property without the right licence can lead to substantial financial penalties, rent repayment orders and difficulties enforcing possession notices. Getting it right early also gives tenants confidence that the home is properly managed and safe.
Guide to landlord licensing rules: start with the property
The first question is not whether you own one property or a large portfolio. It is what type of occupation the property will have, where it is located, and which local authority covers its address.
In England, landlord licensing generally falls into three categories: mandatory HMO licensing, additional licensing and selective licensing. They can overlap with wider landlord duties, including gas safety, electrical safety, smoke and carbon monoxide alarm requirements, deposit protection and the provision of prescribed tenancy information. A licence does not replace those duties. It sits alongside them.
Postcodes are not always a reliable shortcut. SE18, SE28 and SE2 cover areas administered by more than one council, and local schemes are set by the relevant borough. Always check the exact address against the current council designation rather than relying on an agent’s old advice, a neighbour’s experience or a postcode-wide assumption.
Mandatory HMO licensing
A house in multiple occupation, commonly called an HMO, is broadly a property occupied by people from more than one household who share facilities such as a kitchen, bathroom or toilet. A household can include a family, a couple or a single person. Three unrelated friends sharing a flat may therefore be an HMO, depending on the arrangement.
Mandatory licensing usually applies where an HMO is occupied by five or more people forming two or more households and sharing facilities. The property does not need to be a large house. Converted flats and smaller homes can fall within the rules where the occupation meets the test.
The licence application will commonly ask for details of the proposed licence holder, manager, property layout, facilities, safety arrangements and occupiers. Councils can impose conditions about maximum occupancy, waste storage, fire precautions and ongoing management. Minimum room-size requirements also apply to many licensed HMOs, so do not base occupancy only on the number of bedrooms advertised.
Additional licensing
A council may introduce an additional licensing scheme to cover HMOs that do not require a mandatory HMO licence. This can bring smaller shared homes into licensing, for example a property let to three or four unrelated tenants.
Additional schemes are local, time-limited and subject to specific designations. Their boundaries and property types vary. A landlord who changes from a single-family let to a professional house share should check the licensing position before advertising rooms, not after agreements have been signed.
Selective licensing
Selective licensing applies to privately rented homes in a designated area, whether or not they are HMOs. It may cover a straightforward family let, a single-occupier flat or a house rented to a couple. Councils use these schemes where they believe licensing will help address issues such as poor property conditions, anti-social behaviour or ineffective management in a particular area.
This is the category most likely to catch accidental non-compliance. A landlord may have let a conventional two-bedroom house for years without a licence, only to find that a new or renewed local designation now applies. Licensing areas can be tightly drawn, so an address on one side of a road may be treated differently from one nearby.
Check planning before changing how you let
Licensing and planning are separate systems. A property may need an HMO licence, planning permission, both, or neither, depending on its use and the local planning rules.
In many areas, a change from a family dwelling to a small HMO can be affected by an Article 4 Direction. This removes a permitted development right and means planning permission may be required for the change of use. A licence from the council’s private rented sector team is not evidence that planning consent has been granted.
For landlords considering a house share in South East London, it is sensible to assess both questions at the outset. The expected rent can look attractive, but licensing fees, upgraded fire safety measures, room standards, management time and potential planning restrictions all affect the real return. A rental-yield calculation should reflect the cost of compliant operation, not just the headline monthly income.
What a licence application normally involves
Application details differ by council, but the process is more than paying a fee. The proposed licence holder must be a fit and proper person, and the council may also consider the person responsible for day-to-day management.
Prepare accurate documents before applying. You may need current gas and electrical safety records, an energy performance certificate, floor plans, fire-safety information, proof of ownership or management arrangements, and details of tenants. If the property is mortgaged or leasehold, check your lender and lease conditions too. Some leases restrict HMOs or require the freeholder’s consent.
A council inspection may follow, particularly for HMOs. Common issues include inadequate fire doors or alarms, unsafe communal areas, insufficient kitchen and bathroom facilities, poor refuse arrangements and room sizes that do not support the proposed occupancy. Do not wait for an inspection to identify them. A pre-tenancy compliance review is usually less disruptive and less expensive than remedial work during an occupied tenancy.
Licences are granted for a fixed period and are not normally transferable when ownership changes. If you buy a licensed rental property, confirm exactly what will happen to the licence on completion and what application you must make in your own name. The same principle applies if the licence holder, manager or occupancy changes materially.
Avoid the common licensing mistakes
The most frequent mistake is assuming that a managing agent’s involvement removes the landlord’s legal responsibility. An agent can administer the application, arrange certificates and manage repairs, but the property owner must still ensure the correct licence is in place and its conditions are met.
Another is treating a renewal as automatic. Licence expiry dates need to be diarised well in advance. Councils can take time to process applications, and a late renewal can create an avoidable gap. Keep copies of applications, payment confirmations, inspection reports and correspondence in one property file.
Landlords should also be cautious when tenant arrangements evolve. A couple moving out and two individual sharers moving in can change the HMO status. Allowing subletting without clear control can do the same. Regular property inspections, carried out properly and with the required notice, help you understand who is occupying the home and whether the management arrangement still matches the licence.
Finally, do not confuse a licence with a guarantee that every compliance duty has been met. Deposit protection deadlines, right to rent checks, repairs, safety inspections and tenancy paperwork remain active responsibilities throughout the tenancy.
A practical route to staying compliant
Before marketing, establish the intended tenant group and occupancy. Then identify the local authority for the precise address and check whether mandatory HMO, additional or selective licensing applies on the proposed tenancy date. Review planning restrictions separately, particularly where a family home may become a shared house.
Next, cost the work honestly. If improvements are required, factor in the installation work, licensing fee, certification, possible lost rent and ongoing management. For some landlords, a fully managed service is valuable because inspections, renewal dates and repair records are kept in one place. For others, self-management works well, provided there is enough time and knowledge to respond consistently.
Hi Residential can help landlords assess the practical letting and management considerations around a property, while the final licensing decision must always be checked with the relevant local authority. Rules, designations and fees can change, so current written confirmation is worth having before you commit to a tenancy strategy.
A well-run rental is not defined by how quickly it is let, but by whether the arrangement remains safe, lawful and manageable once the keys are handed over. Check the address, check the intended use, and give yourself time to put the right standards in place.
