HMO licensing for letting agents in England: mandatory, additional and selective licences
When a rental is an HMO, when it needs a licence, how long licences last, the conditions that come with one, and the penalties for letting without one.
A shared house can need a licence from the council before it is let, and letting one without a licence is a criminal offence. For an agency managing HMOs, the licence is one more certificate with an expiry date, and one of the most expensive to miss.
This guide explains what counts as an HMO, which HMOs need a licence, how long licences last, and what agencies should track. Checked against gov.uk on 17 September 2026.

What counts as an HMO
A property is a house in multiple occupation when it is rented by at least three people who are not from one household (for example, not one family) and they share facilities like the bathroom or kitchen.
Three kinds of licence
Mandatory licensing
A large HMO must be licensed everywhere in England when:
- it is rented to 5 or more people who form more than one household
- some or all tenants share toilet, bathroom or kitchen facilities
- at least one tenant pays rent (or their employer pays it for them)
Additional licensing
A council can require licences for smaller HMOs in its area too. Whether a three- or four-person HMO needs a licence depends entirely on the council, so check each area you work in.
Selective licensing
Some councils run selective licensing schemes that cover privately rented homes in a designated area, even when they are not HMOs.
What a licence involves
Licences are issued by the council and last up to five years. Fees and application processes vary by council. As a licence holder, a landlord must make sure, among other things, that:
- the house is suitable for the number of occupants
- the manager of the house is considered "fit and proper"
- there is an annual gas safety certificate
- smoke alarms are installed and maintained
- electrical safety certificates can be provided when asked
Councils usually attach conditions to the licence, such as the maximum number of occupants. Keep a copy and brief whoever lets the rooms.
Penalties
Renting out an HMO that needs a licence without one can lead to an unlimited fine on prosecution. Councils can instead impose a civil penalty; since 1 May 2026 the maximum civil penalty for these housing offences has been £40,000, up from £30,000.
Beyond fines, an unlicensed HMO puts the landlord's income and reputation at risk, and an agency that let it has explaining to do.
A checklist for agencies
- Flag every property that is, or could become, an HMO. Occupancy changes mid-tenancy can turn a let into one.
- For each council you work in, record whether additional or selective licensing applies, and where.
- Record the licence number, the maximum occupants and the expiry date against the property.
- Start renewals well before the five-year licence ends; councils can take weeks to process them.
- Never let rooms beyond the licensed number of occupants.
- Keep gas safety, electrical and smoke alarm evidence ready to send to the council.
- Keep a copy of the licence conditions where the lettings team can see them.
For gas, electrical safety, EPCs and Right to Rent, see gas safety certificates, EICR rules, EPC rules and the compliance checklist.
Keeping it on track in Letfold
In Letfold a property can be marked as an HMO with its licence number and maximum occupants, and the HMO licence is stored as a certificate with its expiry date. Owners and managers get email reminders at 60, 30, 14 and 7 days before it expires, on the day, and after it lapses. A council or selective licence can be tracked the same way. See compliance tracking.
