When investing in Houses in Multiple Occupation (HMOs), understanding the distinction between HMO planning and HMO licensing is crucial. These are two separate processes that play a significant role in ensuring compliance with legal requirements and maximizing the profitability of your property. In this article, we’ll explore the key differences, why each is important, and how they intersect.

What is HMO Planning?

HMO planning refers to the planning permissions required to convert or use a property as an HMO. It falls under the jurisdiction of the local planning authority and focuses on the use and development of the property within the context of local planning policies.

When is HMO Planning Permission Required?

Change of Use: If you’re converting a property into an HMO, you may need planning permission for a “change of use.” Properties are classified under different categories in the planning system:

  • C3: Single dwelling (e.g., family home).

  • C4: Small HMO (3-6 unrelated individuals sharing amenities).

  • Sui Generis: Larger HMOs (7 or more unrelated individuals).

A change from C3 to C4 may not always require planning permission unless the local authority has imposed an Article 4 Direction.

Article 4 Direction: Some councils introduce Article 4 Directions to restrict the conversion of properties into HMOs. In these areas, even small HMOs (C4) require explicit planning permission.

Extensions and Alterations: Significant structural changes to the property (e.g., adding extra rooms) may require planning approval.

    Purpose of HMO Planning

    • To manage the density of HMOs in specific areas.
    • To maintain a balance between family homes and rental properties.
    • To ensure developments align with local infrastructure and services.

    Failing to secure the necessary planning permissions can result in enforcement action, fines, or being forced to revert the property back to its original use.

    What is HMO Licensing?

    HMO licensing is a separate legal requirement that focuses on ensuring the property meets health, safety, and management standards for tenants. Licensing is administered by the local council and is aimed at protecting tenants living in shared accommodation.

    When is an HMO License Required?

    1. Mandatory Licensing: Applies to all HMOs housing five or more tenants forming two or more households, regardless of location.
    2. Additional Licensing: Some councils require licenses for smaller HMOs (e.g., 3-4 tenants) through additional licensing schemes.
    3. Selective Licensing: In certain areas, councils may require licenses for all rental properties, not just HMOs, to improve housing standards.

    Purpose of HMO Licensing

    • To ensure the property is safe and complies with fire safety regulations.
    • To confirm adequate room sizes, ventilation, and sanitation facilities.
    • To verify that the landlord is a fit and proper person to manage the property.
    • To enforce tenant safety and welfare standards.

    Operating an unlicensed HMO can result in heavy fines, Rent Repayment Orders (RROs), and even criminal prosecution.

    Do You Need Both HMO Planning and Licensing?

    In many cases, yes. For example:

    • If you’re converting a family home (C3) into a small HMO (C4), you may need planning permission (especially in Article 4 areas) and an HMO license if the property meets the licensing criteria.
    • Larger HMOs (Sui Generis) almost always require both planning permission and licensing.

    It’s important to note that obtaining one doesn’t guarantee the other. For instance, a property may meet licensing requirements but still be denied planning permission due to local planning policies.

    How to Navigate HMO Planning and Licensing

    1. Research Local Policies: Check your local council’s website for details on Article 4 Directions, planning requirements, and licensing schemes.
    2. Engage Professionals:
      • Planning Consultants: Help with planning applications and navigating local policies.
      • HMO Licensing Specialists: Ensure your property meets safety standards.
    3. Conduct Due Diligence:
      • Before purchasing a property, verify whether planning permission or licensing is required.
      • Ensure the property layout and amenities comply with both planning and licensing standards.
    4. Stay Updated: Regulations vary by location and are subject to change. Regularly review local council updates.

    Conclusion

    While HMO planning and HMO licensing serve distinct purposes, they are both essential for legally and successfully operating an HMO. Planning ensures the property’s use aligns with local policies, while licensing safeguards tenant welfare and safety. By understanding their differences and requirements, you can avoid costly mistakes and maximize the potential of your HMO investment.
