Based on the standard legal definitions across the UK, the short answer is no, you do not need a mandatory HMO licence for a property with only two tenants.
The requirement for a mandatory HMO licence is triggered by a higher occupancy threshold. However, the situation requires careful analysis, as local council rules and the specific relationship between the tenants can create exceptions.
The Core Legal Definition
An HMO (House in Multiple Occupation) is legally defined in England as a property rented out by at least 3 people who are not from one ‘household’ (e.g., a family) but share facilities like the bathroom and kitchen.
The Mandatory HMO Licence applies specifically to properties that are:
- Occupied by 5 or more persons.
- Forming 2 or more separate households.
- Sharing basic amenities (toilet, bathroom, or kitchen).
Since your property has only two tenants, it falls below this mandatory threshold.
Key Exceptions and Grey Areas
While a mandatory licence is not required, there are two critical scenarios you must check:
1. Local Council Additional Licensing Schemes
This is the most important factor to verify. Many local councils in the UK have introduced “Additional Licensing” schemes that extend HMO licensing to smaller properties.
- An Additional Licensing scheme can require a licence for HMOs occupied by 3 or 4 people.
- Crucially, some councils have been known to design schemes that could, in theory, encompass certain two-person arrangements, though this is very rare. The vast majority of Additional Licensing schemes start at 3 occupants.
- Action: You must contact your local council or check their website to confirm whether an Additional Licensing scheme is active in your area. This is not a national rule and varies from one street to the next in some cities.
2. The Definition of a “Household”
The need for a licence hinges on the number of households, not just the number of people. A “household” is typically defined as members of the same family living together (e.g., a couple, siblings, parent and child).
- If your two tenants are a couple: They are one household. The property is a single-family let, not an HMO at all, and no licence is needed.
- If your two tenants are unrelated friends or acquaintances: They are two separate households. While this technically meets part of the HMO definition (two households), the total number of people (two) is below the mandatory and typical additional licensing thresholds. Therefore, it is generally not a licensable HMO.
Summary Table: Do You Need a Licence?
| Scenario | Licensable HMO? | Licence Required? |
|---|---|---|
| 2 tenants who are a couple (one household) | No | No |
| 2 unrelated tenants (two households) | Yes, it is technically a small HMO. | No, for a Mandatory Licence. Check locally for Additional Licensing (very unlikely). |
| 3 or more unrelated tenants (two+ households) | Yes | Check for Additional Licensing (likely). |
| 5 or more unrelated tenants (two+ households) | Yes | Yes, Mandatory Licence required. |
Other Legal Responsibilities for a 2-Person Shared House
Even without a licence, if your two tenants are not a couple, the property is still an HMO in the eyes of the law. This means you still have significant legal responsibilities for health and safety, including:
- Fire Safety: Providing and maintaining working smoke alarms on each floor and carbon monoxide alarms in any room with a solid fuel burning appliance (e.g., a coal fire or wood burner).
- Gas Safety: An annual Gas Safety Check by a Gas Safe registered engineer.
- Electrical Safety: Ensuring the electrical system is safe and providing a Electrical Installation Condition Report (EICR) every 5 years.
- Furniture and Furnishings: Ensuring any provided furniture is fire-safe.
- Repairs: Maintaining the structure, exterior, and all installations for the supply of water, gas, electricity, sanitation, and heating.
Conclusion:
For a property with two tenants, you are almost certainly exempt from HMO licensing requirements. However, your final step must be to confirm with your local council that no Additional Licensing scheme applies to your property. Regardless of licensing, you retain your core legal duties as a landlord to provide a safe and well-maintained home. If you are in any doubt, seeking written confirmation from your local council’s environmental health or private rental sector team is the safest course of action.
