Houses in Multiple Occupation (HMOs) offer higher yields but come with additional regulations and management complexity. This guide covers everything UK HMO landlords need to know about compliance and operations in 2026.

Is a couple counted as one or two occupiers?
A couple sharing a bedroom are usually counted as one household but two occupiers. The room size requirements would apply for two people, but they only count as one household for the household count.
Do I need planning permission for an HMO?
Small HMOs (3-6 people) may be permitted development. Large HMOs (7+) typically need planning permission. Many councils have Article 4 directions requiring permission for all HMOs. Check with your local planning authority.
Can I convert a house to an HMO?
You may need planning permission, building regulations approval for alterations, and an HMO licence. Consider costs of fire doors, additional bathrooms, and kitchen upgrades. Some areas restrict new HMOs.
What mortgage do I need for an HMO?
You need an HMO-specific buy-to-let mortgage. Not all lenders offer these, and they often have higher rates than standard BTL mortgages. Lenders will want to see the licence or licence application.
