Three types of licensing. Different triggers. Different areas. Operating without a required licence is a criminal offence — and ignorance of a scheme is not a defence.
Landlord Compliance Management →Key facts at a glance
Landlord licensing is one of the most commonly misunderstood compliance obligations in the private rented sector. Many landlords are unaware that a licence is required for their property. Some assume a licence obtained years ago is still valid. Others know licensing exists but are unclear which type applies, whether their area has a scheme, and what the consequences of operating without one are.
This guide explains the three types of landlord licensing in England, what triggers the requirement for each, how to apply, what conditions licences carry, and what happens if you operate without one. Because selective and additional licensing schemes are declared locally by councils and change regularly, we do not list specific current schemes here — but we explain how to check what applies to your property and why staying current matters.
If you want your licensing compliance managed as part of a broader landlord management service, our compliance-led landlord management service monitors licensing obligations, manages applications, and ensures your properties remain correctly licensed. Available nationwide.
Licensing operates on three distinct tracks with different triggers, different geographic coverage, and different purposes. A property may be subject to more than one type simultaneously.
| Type | Trigger | Who decides | Licence period |
|---|---|---|---|
| Mandatory HMO Licensing | HMO with 5+ occupiers from 2+ households, any number of storeys | National — applies everywhere in England | Up to 5 years |
| Additional Licensing | HMOs not covered by mandatory licensing — e.g. smaller HMOs | Local council — council must designate a scheme | Up to 5 years |
| Selective Licensing | Single-occupation properties (non-HMOs) in designated areas | Local council — Secretary of State approval required for large schemes | Up to 5 years |
National. No local decision required. 5+ occupiers, 2+ households — licence required everywhere in England, no exceptions.
Extends HMO licensing below the mandatory threshold. Local councils designate these. Schemes have end dates and may not be renewed.
The broadest type. Applies to all privately rented properties — including single-occupier flats — in designated areas. Most relevant for London landlords.
Mandatory HMO licensing applies nationally across England. It is not a local scheme — it applies everywhere, regardless of whether your council has declared any additional or selective licensing.
A property occupied by three or more people who form two or more separate households and share facilities. Three unrelated sharers with a shared kitchen = HMO. A couple and a single person in the same house = also an HMO.
When a property is occupied by five or more people forming two or more households, regardless of the number of storeys. Fewer occupiers may still require a licence under an additional licensing scheme.
Minimum room sizes apply to mandatory HMO licences. Regulations introduced in 2018 set minimum floor areas for sleeping rooms: 6.51m² for a single adult, 10.22m² for two adults sharing. Rooms below these sizes cannot be used as sleeping accommodation. Check before applying.
Additional licensing extends the HMO licensing requirement beyond the mandatory threshold. A council that declares an additional licensing scheme can require licences for HMOs that fall below the five-occupier mandatory threshold — for example, requiring all HMOs with three or more occupiers to be licensed.
Additional licensing is a local decision. Schemes have a maximum duration of five years and must be renewed. A scheme that has not been renewed has expired — but a new scheme may have replaced it.
London boroughs in particular have been active in declaring additional licensing schemes. Several East London and North London boroughs have borough-wide or near-borough-wide additional licensing schemes covering HMOs well below the mandatory threshold. If you let property in London, the probability that at least one of your properties is in an additional licensing area is high.
Selective licensing is the broadest form of landlord licensing. It applies to all privately rented properties in a designated area — not just HMOs. A single-occupier flat in a selective licensing area requires a licence in exactly the same way as a large HMO in a mandatory licensing area.
Selective licensing can only be declared in areas where one or more specified conditions exist — low housing demand, significant anti-social behaviour, high levels of deprivation, high levels of migration, or significant levels of crime. Schemes covering more than 20% of the council's area or 20% of the private rented stock require approval from the Secretary of State.
Every landlord letting a private residential property in England. It is not enough to check once — new schemes are declared regularly, existing schemes are renewed, and boundaries change. A property outside a selective licensing area two years ago may be inside one today.
Several London boroughs have declared or renewed selective licensing schemes in recent years, in some cases covering large portions of the borough's private rented stock. Boroughs across East London and North London have been among the most active. Checking current selective licensing coverage for each property is not optional — it is a basic compliance step.
Ignorance of a scheme is not a defence. Councils do not contact every landlord in a newly designated area to inform them that a scheme has been declared. The obligation to know whether your property is in a licensing area sits with the landlord. A council that discovers an unlicensed property will not accept 'I didn't know there was a scheme' as a reason to waive the penalty.
Obtaining a licence is only the first step. Licences come with conditions that must be maintained throughout the licence period. Breach of licence conditions is itself an offence and can result in the licence being revoked.
| Condition | What it requires |
|---|---|
| Gas safety | Valid gas safety certificate annually. Certificate provided to tenants within 28 days of check. See gas safety certificate requirements. |
| Electrical safety | Valid EICR (Electrical Installation Condition Report) every five years. Remedial works completed within required timeframe. |
| Smoke & CO alarms | Working smoke alarm on every storey. Carbon monoxide alarm in any room with a fixed combustion appliance. Tested at start of each tenancy. |
| Energy Performance Certificate | Valid EPC for the property. Current minimum rating E — check for updated minimum rating requirements. |
| Tenancy agreement | Written tenancy agreement provided to all occupants. |
| HMO: fire safety | Fire doors, fire detection system, emergency lighting, and escape routes appropriate to the size and layout of the HMO. Specific requirements vary by HMO type. |
| HMO: room sizes | Sleeping rooms must meet minimum floor area requirements. Rooms below minimum size cannot be used as sleeping accommodation. |
| Property management | Property maintained to required standard. Tenant complaints responded to. Anti-social behaviour managed. |
| Licence renewal | Licence must be renewed before expiry. Operating on an expired licence is the same as operating without one. |
The consequences of letting a licensable property without a licence are serious — including criminal prosecution, substantial financial penalties, and loss of the right to use certain legal processes against tenants.
| Consequence | Detail |
|---|---|
| Criminal prosecution | Operating without a mandatory HMO licence is a criminal offence. Unlimited fine on conviction. |
| Civil penalty notice | Councils can issue civil penalty notices of up to £30,000 per offence as an alternative to prosecution. |
| Rent Repayment Order | Tenants (and local authorities) can apply to the First-tier Tribunal for a Rent Repayment Order requiring repayment of up to 12 months' rent. |
| Section 21 invalidity | A Section 21 notice cannot be validly served while a property requires a licence that has not been obtained. (While Section 21 remains in force.) |
| Section 8 restrictions | Certain Section 8 grounds may also be unavailable to unlicensed landlords depending on the specific licensing type. |
| Licence condition breach | Breach of licence conditions: up to £5,000 fine. Licence may be revoked. |
The only reliable way to establish your current licensing position is to check with each local council where your properties are located. Most councils publish licensing scheme information on their websites, but the quality and currency of this information varies. Some councils have online postcode checkers. Others require you to call the private sector housing team directly.
For mandatory HMO licensing, the trigger is national and consistent — five or more occupiers from two or more households. If your property meets that threshold, a mandatory licence is required everywhere in England.
For additional and selective licensing, the position changes with each scheme declaration, renewal, and boundary change. A property that required no licence under a scheme that has expired may now require one under a new scheme with different boundaries. Checking once is not enough.
Apply immediately. Some councils offer a more favourable position to landlords who proactively apply once they discover they are unlicensed, compared to those discovered through enforcement. Document when you became aware, what you did in response, and how quickly you applied.
This does not eliminate liability but may influence the level of penalty. Seek legal advice if a Rent Repayment Order application has been made or looks likely.
