Trying to get clear on room size requirements for an HMO license in England. Does a 6.5sqm room actually count as a 'habitable' bedroom for one person, or will the council reject it?

Quick Answer

While the national minimum for a single HMO bedroom is 6.51m², many local councils enforce higher minimums of 7.5m² or 8m² as part of their housing standards. Always verify local council requirements.

## Understanding HMO Room Size Minimums for Licensing Mandatory HMO licensing in England stipulates specific minimum room sizes. For a single bedroom occupied by one person, the legal minimum requirement is 6.51 square metres. For two people, the minimum doubles to 10.22 square metres. These figures are set nationally. However, local authorities retain discretionary powers to implement higher minimum room sizes within their specific Private Sector Housing Enforcement Policies. For instance, many councils now demand closer to 7.5m² or 8m² per person to approve a new HMO license application, citing local housing standards and tenant welfare, impacting feasibility and profitability for HMO investors. ### Does My Local Council Have Higher Standards? Yes, many local councils do exercise their right to impose higher minimum room sizes. While the national legal minimum for a single person's bedroom is 6.51m², councils like Leicester, Nottingham, and many London boroughs have adopted their own minimums, often ranging from 7m² to 8m² for single occupancy. This means a room of 6.51m² might not be accepted by your local authority, even though it meets the national statutory minimum. For example, a property investor planning a five-bedroom HMO in a borough requiring 7.5m² per single room would find a 6.51m² room rejected, potentially reducing their viable room count and overall rental income capacity. This also affects HMO valuation and the ability to secure appropriate HMO finance. ### What are the Implications if a Room is Too Small? If a room fails to meet either the national minimum (6.51m² for one person) or the local authority's higher threshold, it cannot be legally let out as a bedroom within a licensed HMO. This has direct financial implications for investors. For instance, converting a four-bedroom property into a five-bedroom HMO with one room at 7m² and another at 6.5m² could result in the smaller room being disallowed for occupancy, effectively making it a four-bedroom HMO in terms of licensing. This reduces projected rental income, potentially by £400-£600 per month depending on area, and affects rental yield calculations. Also, a failure to comply can lead to prosecution, fines up to £30,000, and Rent Repayment Orders, where tenants can claim back up to 12 months' rent. ### How Can I Confirm My Council's Requirements? The most reliable way to confirm room size requirements is to check your specific local council's website under their 'Private Rented Sector' or 'HMO Licensing' sections. Many councils publish detailed guidance documents or specific policies on minimum room sizes that exceed the national 6.51m² standard. For example, search for "[Your Council Name] HMO room sizes policy" online. Alternatively, contacting the local authority's Private Sector Housing or Environmental Health department directly will provide clarity. Understanding these specific local nuances is critical for accurate HMO deal analysis and ensuring compliance, avoiding potential issues with HMO licensing and future tenancy agreements. Also, consider the impact of Awaab's Law, extending damp/mould response requirements to the private sector, which could influence how councils assess overall habitability.

Steven's Take

The disparity between national minimums and local council standards for HMO room sizes is a common pitfall. Many investors assume 6.51m² is universally accepted, only to find their local authority demands more. I always advise investors to verify with the specific council at the outset of any HMO project. This due diligence ensures your projected cash flow and occupancy numbers are realistic, preventing costly mistakes and potentially illegal operations. It’s an easy check that can save significant problems down the line.

What You Can Do Next

Step 1: Identify your specific local authority - Check the council's website (e.g., 'gov.uk/find-your-local-council' to find the relevant local authority for your investment property). This is crucial as local policies can vary significantly.
Step 2: Review the local council's Private Sector Housing Policies - Search the identified council's website for 'HMO licensing requirements', 'private sector housing standards', or 'room size standards'. Most councils publish their specific criteria and application guides.
Step 3: Contact the Local Authority directly - If you cannot find clear information online, call the council's Private Sector Housing or Environmental Health department. Request written confirmation of their minimum room size requirements for licensed HMOs to avoid any future disputes.
Step 4: Consult a specialist HMO architect or planning consultant - Engage a local professional with experience in HMO planning and licensing. They can advise on property-specific room configurations and ensure compliance with both national and local regulations before you begin any conversion work, mitigating the risk of rejection.
