The Importance of Minimum Room Sizes in HMO Properties

August 28, 2025

When it comes to investing in Houses in Multiple Occupation (HMOs) one of the most overlooked but crucial elements is compliance with minimum room sizes in HMO properties. Time and time again we see landlords or developers attempt to create their own HMO without a clear understanding of the required room and communal area sizes. The result is often wasted money and properties that simply cannot operate legally.

How Foot Forward Protects Investors

At Foot Forward we pride ourselves on ensuring that every HMO property investment we sell is fully compliant with all rules and regulations. When an investor buys a property from us they can do so with confidence knowing that every bedroom and every communal area meets the required standards. We remove the guesswork and the risk so that investors can focus on growing their portfolio with peace of mind. By buying a compliant HMO through us, investors avoid the stress and expense of dealing with non compliant properties.

Why Minimum Room Sizes Matter

The HMO regulations in the UK around minimum room sizes are not arbitrary. They exist to ensure that tenants have a safe and habitable standard of living. Local councils take these rules seriously and failing to comply can lead to major setbacks for investors including refusal or removal of an HMO licence.

Unfortunately many people enter the HMO market chasing low purchase prices without looking closely at compliance. We have even been offered HMO properties to purchase that did not meet the required room size standards. Needless to say we strongly declined those opportunities because buying a non compliant HMO is a guaranteed problem for the future.

The Risks of Buying Cheap Non Compliant HMOs

We regularly hear stories from landlords who buy what they think is a bargain HMO only to find that one or two of the bedrooms fall below the minimum size requirements. At first this may not seem like an issue if tenants are already living there. However when the time comes for HMO licence renewal the council will flag those undersized rooms as not large enough and therefore illegal to let out. Suddenly the property has lost two income producing rooms and the whole investment becomes less profitable or even unviable.

This is the risk many face when buying cheap HMO properties without doing their due diligence. Compliance should never be an afterthought because once the property is flagged you may have no option but to lose rental income or spend heavily on alterations.

Final Thoughts

The importance of minimum room sizes in HMO properties cannot be overstated. Too many people buy properties that appear cheap only to discover later that compliance issues wipe out their returns. By working with experts who understand HMO property investment compliance you avoid costly mistakes and ensure your HMO investment is sustainable and profitable. With Foot Forward every investor has the confidence of knowing they are buying a compliant HMO that meets all UK HMO regulations.
