HMO licensing is a creature of the Housing Act 2004, not the Renters' Rights Act. It wasn't rewritten in 2025, but enforcement has tightened, civil penalties have grown, and Rent Repayment Orders now follow a failed licence check within weeks. Every room in a licensed HMO should be let on an HMO tenancy agreement template drafted per room. Here's the licensing decision tree.
Is my property an HMO?
A property is an HMO if it is occupied by three or more people forming two or more households, sharing a kitchen, bathroom or toilet. A 'household' is a family unit or a single person. Five unrelated adults in a five-bedroom house? That is an HMO. Four unrelated adults sharing? That is an HMO. Two couples sharing? Still an HMO (two households).
The three licensing tiers
- Mandatory (Part 2, Housing Act 2004), any HMO with five or more persons in two or more households sharing at least one facility. Universal across England, no local designation needed. Section 257 HMOs (pre-1991 building-regs flat conversions) also require licensing.
- Additional (Section 56), a council-wide or ward-based designation extending licensing to smaller HMOs (e.g. three or four persons). Active in roughly 80 councils; designations are renewed every five years.
- Selective (Section 80), single-household lets in a designated area, most common in coastal towns and inner-city wards. Grounds for designation include anti-social behaviour, poor property conditions, and deprivation; roughly 70 councils have active selective schemes. Schemes covering more than 20% of a council area require Secretary of State confirmation.
The pitfall that catches most landlords
A property you bought as a four-bed family home and now let to four sharers is an HMO the moment the fourth unrelated person moves in. If the council has an additional licensing scheme covering your ward, you need a licence, immediately. The tenancies change too: each sharer should be on a per-room HMO tenancy agreement, not a family-let contract. Landlords who miss this have been hit with civil penalties up to £40,000 per property and Rent Repayment Orders covering up to 24 months of rent.
Search '[council name] HMO licensing' and look for active 'additional' or 'selective' schemes. Our HMO Landlord Bundle covers the per-room tenancy agreement, licensing application pack, and compliance checklist, everything to set up and run a compliant HMO in one purchase.
What a licence actually requires
- Fit-and-proper-person declaration by the landlord (and by the managing agent, if used).
- Minimum room-size compliance (6.51 m² single, 10.22 m² double, national minima; council-set minima are often larger).
- Fire detection to BS 5839 Grade D LD2 standard with interlinked alarms.
- Annual gas safety certificate and 5-yearly EICR, same as any let, but enforced per room in an HMO.
- Emergency lighting in shared escape routes (required in larger HMOs).
- Maximum occupancy as specified on the licence, and adequate bathroom, WC and kitchen provision for the number of occupants.
- Compliance with the HMO Management Regulations 2006: drainage, water supply, refuse disposal, structural repairs.
- Written management and maintenance schedule.
Penalties and enforcement
- Criminal prosecution: unlimited fine on summary conviction in the magistrates' court
- Civil penalty: up to £40,000 per unlicensed property, issued by the local authority as an alternative to prosecution
- Rent Repayment Order (RRO): tenants (or the council) can apply to the First-tier Tribunal to recover up to 24 months' rent paid during the unlicensed period
- Management order: the council can take over management of the property via an Interim Management Order
- Rogue landlord database: criminal convictions for HMO offences are publicly recorded
- Banning order: repeat offenders can be banned from letting properties for up to five years
After licensing
A licence runs for up to 5 years. You must notify the council of any material change (extra storey, change of manager, change of occupancy) within 28 days. Licensing fees vary by council from £400 to £2,000+ per property, build this into your pricing. The Landlord Annual Compliance Checklist (£19) covers every HMO compliance touchpoint; gas, electrical, EPC, fire detection, licensing, and the new landlord database, in a single annual walk-through.
