HMO rules for landlords
HMO rules in England sit in the Housing Act 2004, the 2006 management regulations and the local licensing scheme. Three or more people from more than one household who share a kitchen, bathroom or toilet usually make an HMO. The definition and the licence are separate. See what counts as an HMO. Specialist HMO mortgages treat the same rules as credit conditions.

| Minimum bedroom sizes | Housing Act 2004 Sch 4; SI 2018/616 | Council | Occupancy cut; failed valuation |

Licensing rules
A mandatory HMO licence usually applies at five or more occupiers from two or more households. Additional licensing can cover three- and four-person HMOs. Selective licensing can cover any rented house on a designated street. Licences are not transferable on sale. Lenders want a live licence or a submitted application before funds are released.
Room size and amenity rules
National minimum sleeping-room sizes for licensed HMOs in England are 6.51m² (one person over 10), 10.22m² (two over 10) and 4.64m² (one child under 10). Area under a 1.5m ceiling does not count. Councils can set higher kitchen and bathroom ratios. See HMO room sizes.
Fire safety rules
Licensed HMOs need a fire risk assessment, working alarms and a clear escape route. The HMO fire regulations guide covers detection and doors. A missing closer can stall a valuation even when the paper licence is in date.
Management regulations and landlord duties
The 2006 regulations apply whether or not a licence is needed: keep shared areas in repair, provide bins, maintain fire precautions and display the manager's details.
Gas, electrical and EPC
A current gas safety record, EICR and EPC are standard licence and mortgage documents. Gaps here delay completion more often than a missing payslip.
HMO council tax: who pays and how it is charged
Some houses are one band paid by the landlord. Some conversions have a band per unit. Student exemptions are not automatic. Confirm banding with the billing authority before you model cash flow.
Planning rules
Small HMOs are often C4. Seven or more occupiers are usually sui generis. Article 4 can remove C3-to-C4 permitted development. Planning and licensing are separate consents.
Penalties and enforcement
Letting a licensable HMO without a licence is a criminal offence. Councils can prosecute or issue a civil penalty of up to £40,000. Rent repayment orders can cover up to two years' rent. Check how this affects your HMO mortgages case before you exchange.
FAQs
