# HMO Licensing in 2026: Mandatory, Additional and Selective Explained
Quick Answer
If you rent to five or more people from two or more households sharing facilities, you almost certainly need a mandatory HMO licence from your local council. On top of that, many councils run additional HMO licensing (for smaller HMOs) and selective licensing (for any private rented property in a designated area). Letting without a required licence can lead to a Rent Repayment Order of up to 12 months' rent, an unlimited fine and a banning order.
Key Takeaways
- Mandatory HMO licence: required for any HMO with 5+ occupants from 2+ households.
- Additional licensing: councils can extend licensing to smaller HMOs (3–4 occupants).
- Selective licensing: councils can require a licence for every privately rented property in a designated area, regardless of HMO status.
- Letting unlicensed exposes you to a Rent Repayment Order, unlimited fines, and PRS Database entry as a non-compliant landlord.
- Licences typically last 5 years and cost £500–£1,500 depending on the scheme.
What Has Changed?
Tighter enforcement under the Renters' Rights Act
The Renters' Rights Act and the Private Rented Sector Database mean every licensable property is now tracked nationally. Councils share data with HMRC, the Home Office and tenancy deposit schemes — an unlicensed HMO is harder than ever to hide.
Banning orders and rogue landlord databases
A serious or repeated breach can land you on the national rogue landlord database. Banning orders prevent you from letting any property in England for at least 12 months.
Council Tax recategorisation
From 2024, individual rooms in HMOs are no longer separately banded for Council Tax in most cases — the whole HMO is one band, and the landlord is liable. This has shifted the economics of HMO investment.
The Three Types of HMO Licensing
Mandatory HMO licensing
Required nationwide when:
- 5+ occupants from 2+ households
- Sharing one or more amenities (kitchen, bathroom, toilet)
What counts as a household
- A single person
- Members of the same family living together (couples, parents and children)
- A cohabiting couple
So 5 unrelated sharers = mandatory licence. A family of 5 = not an HMO.
Additional HMO licensing
Councils may designate any HMO not covered by mandatory licensing (typically 3–4 occupants from 2+ households). Each scheme runs for up to 5 years and must be re-consulted.
Selective licensing
A council can designate an area where every privately rented property — HMO or single household — needs a licence. Typically applied in areas with:
- Low housing demand
- High levels of anti-social behaviour
- Persistent disrepair issues
Examples in 2026 include parts of Norwich, Newham, Liverpool and Nottingham.
What Landlords Need To Do Now
Step 1: Identify whether your property is an HMO
Use this checklist:
- How many unrelated occupants live there?
- Do they share a kitchen, bathroom or toilet?
- Is it their main residence?
If yes to all and you have 3+ unrelated occupants, you may need a licence under additional licensing — check your council's website.
Step 2: Check your council's licensing schemes
Search "[council name] HMO licensing" and "[council name] selective licensing". Read the designation document — it lists exactly which streets and property types are covered.
Step 3: Apply before you let
Apply through the council's online portal. You'll need:
- Property floor plan
- Gas Safety, EICR, EPC certificates
- Fire risk assessment
- Proof of identity and right to be in the UK
- DBS check (some councils)
- Management agreement (if using an agent)
Processing usually takes 8–16 weeks.
Step 4: Comply with licence conditions
Typical conditions include:
- Annual gas safety, 5-year electrical
- Working smoke alarms on every storey
- CO alarm in every room with a fuel-burning appliance
- Minimum room sizes (6.51 m² for a single, 10.22 m² for a double)
- Fire doors with self-closers
- Refuse storage and disposal arrangements
- 24-hour landlord contact details posted in the property
Step 5: Renew at month 54
Licences last 5 years. Diary the renewal at 60 days before expiry to avoid lapsing into unlicensed letting.
Common Mistakes To Avoid
1. Assuming "only 4 sharers" means no licence
If your council has additional licensing, a 3-person HMO can still need a licence.
2. Ignoring selective licensing
Even a single tenant family can need a licence if the property is in a selective licensing area.
3. Letting before the licence is granted
Apply early. A temporary exemption notice gives you 3 months while you remedy issues, but you cannot apply for one twice running.
4. Forgetting Article 4 directions
In an Article 4 area, you also need planning permission to convert from C3 (single dwelling) to C4 (small HMO). Licensing and planning are separate.
5. Missing the fit and proper person test
A criminal record, immigration breach or housing offence can disqualify you. Disclose everything — councils will check.
6. Underestimating the cost
Licensing fees, fire works, room-size compliance and reduced rental yield (one HMO Council Tax band) can shift your maths.
7. Missing renewal
A lapsed licence = unlicensed letting = Rent Repayment Order risk.
