Is Your HMO Development Compliant? New Tribunal Ruling Clarifies In-Room Amenities

By January 12, 2026No Comments

For any residential developer in London or landlord operating in the co-living space, staying on top of shifting regulations is the difference between a high-yield investment and a legal headache.


A recent tribunal ruling has finally provided much-needed clarity for the UK rental market, specifically regarding what constitutes a “self-contained flat” versus a high-quality HMO (House in Multiple Occupation) room.


If you are an HMO developer in South West London or across the capital, this decision could significantly impact your design strategy and planning approach.

The Ruling: “Plugging in a Microwave Does Not Make a Room a Flat”

The tribunal was tasked with deciding whether adding minor amenities—such as microwaves, kettles, or mini-fridges—to individual HMO rooms effectively turned them into self-contained units. This is a critical distinction, as a “change of use” from an HMO to a series of self-contained flats triggers entirely different planning requirements, building regulations, and tax implications.


The judge’s ruling was refreshingly clear: “Plugging in a microwave does not make a room a flat.”


The tribunal confirmed that these additions are considered positive improvements to living standards. As long as residents continue to rely on shared kitchens and communal facilities for their main cooking and socialising, these in-room upgrades do not change the lawful use of the property.

Why This Matters for Residential Developers in London

This is a significant win for any HMO developer in London looking to improve resident wellbeing and safety. In a competitive rental market, modern tenants expect more than just a bed; they want convenience and a touch of autonomy.

This ruling provides the legal reassurance that you can upgrade your rooms to meet these modern expectations without the risk of:

  • Triggering an accidental ‘change of use’ planning application.
  • Facing complex re-classification by local authorities.
  • Violating density or space standards required for self-contained dwellings.

However, the caveat remains: the rooms must not include full kitchen installations (like ovens and hobs) that enable entirely independent living.

Optimising Your Property with Expert Planning and Design Services

Staying on the right side of HMO regulations is vital for a successful, compliant development. While this ruling offers flexibility, the line between an “upgraded room” and a “self-contained unit” can still be thin in the eyes of some local councils.
