Houses of Multiple Occupation (HMOs)
As of December 2025, Hillingdon Council has made changes to the planning rules for houses of multiple occupation.
What's changed?
It is now necessary to obtain planning permission to convert a dwelling (Use Class C3) to an HMO with 3 or more unrelated people sharing (Use Class C4) in all parts of the borough. Previously, this was only required in the wards of Brunel and Uxbridge South.
Please note: Planning permission is already required for properties shared by 7 or more unrelated people (Sui Generis).
Why the change?
The council decided to implement this Article 4 direction at the Full Council Meeting on 27 November 2025.
