Secured Loan on an HMO Property

HMO Licensing Requirements and Compliance

All HMOs with five or more occupants in England require a mandatory HMO licence from the local authority under the Housing Act 2004 and the Licensing of Houses in Multiple Occupation (Prescribed Descriptions) (England) Order 2018. Many local authorities have also introduced additional or selective licensing schemes that extend requirements to smaller HMOs. Licensing requirements cover fire safety standards, room sizes (minimum 6.51m² for single occupants, 10.22m² for couples), management obligations and property condition, and licences must be renewed periodically — typically every five years.

Any secured loan lender considering an HMO as security will want to see evidence that the property holds the required licences and complies with the relevant standards. An unlicensed HMO is a criminal liability for the landlord and a significant risk for any lender, as it could be subject to enforcement action including civil penalty orders of up to £30,000 per offence, banning orders, and rent repayment orders from tenants covering up to 12 months of rent.

Lenders will also check whether there are any outstanding enforcement notices or compliance issues with the local authority. Before applying for a secured loan on an HMO, it is worth ensuring all licensing is in order and that any outstanding compliance matters have been resolved. The compliance landscape for HMOs is also subject to frequent change, and requirements vary significantly between local authorities. Specialist HMO lenders typically have in-house expertise to assess compliance across different council areas.

Article 4 Directions and Planning Considerations

In many urban areas with high concentrations of student or professional HMOs, local authorities have introduced Article 4 directions that remove permitted development rights and require planning permission for the conversion of a standard family home (Use Class C3) to an HMO (Use Class C4 for small HMOs with up to 6 occupants, or sui generis for larger HMOs). Article 4 directions are particularly common in university towns and cities such as Oxford, Cambridge, Bristol, Leeds, Newcastle, Nottingham and Manchester.

Where an Article 4 direction is in force, any property operating as an HMO without the required planning permission is potentially subject to enforcement action. Lenders will check the planning status of an HMO property and will want evidence of the relevant planning permission where Article 4 applies. Your solicitor can obtain planning history via a CON29 search and direct confirmation from the local planning authority.

The existence of an Article 4 direction can actually support the value of an HMO that has the correct permission, as it restricts further HMO conversions in the area and therefore limits competition. However, it also means that a property used as an HMO without permission would need to revert to residential use if sold, which affects its investment value and therefore its value as security.

Rental Income Assessment for HMOs

Standard buy-to-let mortgage assessment criteria — which typically look at the rental income as a multiple of the mortgage payment (interest coverage ratio of 125-145%) — do not translate straightforwardly to HMOs. HMO income is the aggregate of multiple room rents, and lenders need to consider the likely void rate (typically 10-15% for HMOs versus 5% for single lets), the cost of maintaining HMO standards, licensing fees and management costs (typically higher for HMOs than single lets due to higher tenant turnover).

Specialist HMO lenders apply different income assessment methodologies. Some use a commercial valuation approach based on investment yield rather than a simple income coverage ratio. Others will assess the property on both its HMO value and its open market value as a single-family home, and will lend against the lower of the two — this protects them if the HMO use is ever challenged.

For secured loans on owner-occupied properties that are also used as HMOs — for example, where the owner lives in the property and rents rooms to lodgers under the Rent a Room Scheme (tax-free allowance of £7,500 per year for 2025/26) — the assessment will need to consider both the owner’s personal income and the rental income from the HMO rooms. This is a relatively unusual arrangement but one that some specialist lenders will consider.

Specialist Lenders for HMO Second Charge Loans

The market for second charge loans on HMOs is much smaller than for standard buy-to-let properties. Most of the major second charge lenders either exclude HMOs entirely or require the property to meet specific criteria — such as having no more than six bedrooms or being operated under a valid HMO licence — before they will consider it.

Specialist lenders and those with a dedicated commercial property or complex buy-to-let team are the most likely source of HMO second charge finance. Together Money, United Trust Bank, Shawbrook Bank and certain bridging lenders with term loan capabilities are examples of lenders who have historically been active in this space, though their criteria change and availability should always be confirmed with a broker.

It is also worth considering whether a commercial mortgage or bridging loan might be a more appropriate funding structure for an HMO than a conventional secured loan, particularly for larger or more complex properties. A whole-of-market broker who understands both residential and commercial lending can advise on the full range of options available. Rates for HMO secured loans typically carry a premium of 1.0-2.5 per cent over standard residential secured loans to reflect the additional complexity and risk. The legal costs are also typically higher as the HMO-specific checks require more work from the lender’s solicitors.

Indicative HMO Lender Criteria

The table below gives an illustrative overview of specialist HMO second charge lender appetite. Individual criteria change regularly.

Lender	Max Bedrooms	Max CLTV	Article 4 Planning	Licence Required
Together Money	10	70%	Evidence required	Yes where applicable
United Trust Bank	8	70%	Evidence required	Yes
Shawbrook Bank	6	75%	Evidence required	Yes
Pepper Money (selective)	6	70%	Evidence required	Yes
Specialist bridging-to-term	12+	65%	Evidence required	Yes

Typical documentation required includes the HMO licence itself, fire risk assessment, gas safety certificate, electrical installation condition report (EICR), energy performance certificate (minimum EPC E from 1 April 2020, moving to C for new tenancies from 2025-2030 subject to legislation), tenancy schedule showing current rent per room, and planning permission where Article 4 applies. Expect completion to take 8-14 weeks from broker application.

Worked Example: Six-Bed Student HMO in Nottingham

Consider a landlord who owns a six-bedroom licensed student HMO in Nottingham valued at £385,000. The property has a first-charge buy-to-let mortgage of £230,000 at 5.49% (fixed for three more years) and gross rental income of £2,850 per month (six rooms at £475 each inclusive of bills). The landlord wants to raise £45,000 to fund the deposit on another rental property and to upgrade the electrical installation on the current HMO.

Combined LTV including the new loan would be 71.4%, within specialist lender thresholds. Together Money quotes a 12-year term at an APRC of 10.9%, monthly payment of £539, total amount payable of approximately £77,610 including fees. The lender accepts the property based on its valid HMO licence, valid planning (Article 4 area), satisfactory EICR and EPC C rating.

Net rental income after 12% void/management allowance is £2,508 per month. New total financing cost (first charge £1,050 plus second charge £539) is £1,589, leaving positive monthly cash flow of £919. The landlord proceeds after the seven-day reflection period. Completion takes 10 weeks from application due to additional HMO compliance checks. The electrical upgrade protects future licence renewals and tenant demand.

Consumer Protections and Regulatory Considerations

A second charge loan on an HMO may be regulated (consumer buy-to-let, or where the HMO is the borrower’s own home) or unregulated (pure investment buy-to-let). Regulated loans benefit from full FCA MCOB protections including a mandatory ESIS, affordability assessment and seven-day reflection period. Unregulated loans are governed by contract law and the lender’s voluntary codes, though reputable specialist lenders typically follow equivalent standards and are still subject to the FCA Consumer Duty (in force from 31 July 2023) where applicable.

Even on unregulated lending, many specialist HMO lenders voluntarily offer a comparable reflection period and ESIS-like disclosure. It is worth asking your broker to confirm the regulatory status of any loan offer and to explain what protections apply. The FCA Register allows you to check that both broker and lender are properly authorised for the type of lending proposed.

Complaints about regulated lending can be escalated to the Financial Ombudsman Service (FOS) free of charge, with awards of up to £430,000 for acts or omissions from 1 April 2025. Unregulated lending complaints must be pursued through the courts or any contractual arbitration mechanism specified in the loan documents. HMO-specific complaints about licensing or housing conditions are matters for the local authority, not the FCA or FOS.
