Licensing schemes in force

In force

Not in force

Selective licensing

No selective scheme is in force. Selective licensing covers all privately rented homes in a designated area, not just HMOs.

Article 4 direction

In force

An Article 4 direction removes permitted development rights for HMO conversion in part or all of Hillingdon. Converting a family home (C3) to a small HMO (C4) needs planning permission inside the direction area. Large HMOs of 7+ occupants are sui generis and always need permission.

Hillingdon Council has enforced a borough-wide Article 4 Direction. Landlords across all 21 wards must now obtain planning permission to convert a single family home (Use Class C3) into a small House in Multiple Occupation (HMO) for 3–6 unrelated people (Use Class C4)

Hillingdon HMO questions, answered plainly

Do I need an HMO licence in Hillingdon?+

You need a mandatory HMO licence if your Hillingdon property houses 5 or more people from 2 or more households sharing facilities. This is the England-wide mandatory rule under the Housing Act 2004.

Confirm the current position with the council before accepting tenants.

Does Hillingdon have an Article 4 direction for HMOs?+

Yes. An Article 4 direction is in force in Hillingdon (or part of it), which means planning permission is required to convert a family home (C3) to a small HMO (C4, up to 6 occupants). Check the exact boundary with the planning department, because directions often cover specific wards rather than the whole district.
