HMO Licensing in England: Do You Need a Licence and How to Apply
HMO licensing in England: mandatory (5+ unrelated), additional, selective. Penalties: unlimited fines + rent repayment orders. How to check and apply.
An HMO — a House in Multiple Occupation — isn't just a house share. It's a legal classification with stricter safety rules, mandatory licensing, and brutal penalties if you get it wrong.
Many landlords don't know whether their property is an HMO. A house with 5+ unrelated people sharing a kitchen and bathroom — even a modest two-bedroom terrace — is an HMO. If it is, you need a licence. No exceptions.
Get it wrong and the penalties are severe: unlimited fines, criminal conviction, rent repayment orders (tenants can claw back up to 12 months' rent), and banning orders. This isn't a fine you pay and move on. It's a court case costing tens of thousands.
This guide covers what an HMO is, who needs to licence theirs, costs, rules, and how to apply in England.
What Exactly Is an HMO? (England)
An HMO is a property occupied by 5+ unrelated people who share facilities — kitchen, bathroom, or both. The key word: unrelated. Two couples living together = one household, not an HMO. A couple plus two single friends = two households = HMO if they share facilities.
Definition (Housing Act 2004, Section 254, as applied in England): 5+ people forming 2+ households, sharing essential facilities.
Quick examples:
- Five students renting separate bedrooms, sharing kitchen and bathroom = HMO
- Couple + single person sharing flat = Not an HMO
- Four friends, separate tenancies, one kitchen = HMO
Why Does HMO Status Matter?
HMOs trigger stricter safety rules than standard lettings: interlinked smoke alarms in all rooms, fire doors, emergency lighting, minimum room sizes (6.51 m² single, 10.22 m² double), EICR (every 5 years), CP12 gas cert (annually), and amenity ratios (one bathroom per 2 residents, one kitchen per 4). Landlords must be "fit and proper" — no unspent convictions, no housing breaches in 6 years. These rules exist because HMOs historically have the worst safety records and fire death rates.
The Three Licensing Regimes in England
England has three separate licensing schemes. They overlap, and they're confusing. A single property can be caught by more than one.
1. Mandatory HMO Licensing (England-wide)
Applies to: 5+ unrelated people in 2+ households sharing facilities (bathroom, kitchen, toilet).
No exceptions. Size or storeys don't matter — the 3-storey rule was removed in 2018. A 2-storey house with 5 tenants is subject to mandatory licensing.
Issuing authority: Your local authority (council).
Duration: 5 years.
Cost: £500–£1,200 (varies by council).
You must apply before letting the property. No licence = no letting.
Can't be avoided. You can't dodge it by restructuring tenancies or telling tenants "this isn't an HMO." If it meets the definition, it's an HMO.
2. Additional Licensing (Some Councils)
Applies to: Smaller HMOs (usually 3–4 unrelated people) in designated areas.
Not all councils have it. Check your council's website.
Issuing authority: The council (if designated).
Duration: Usually 5 years.
Cost: £200–£600 (varies).
It's discretionary. If your council has designated your area, you must licence even 3-person HMOs. Check your council's private rented sector licensing page.
3. Selective Licensing (Some Councils)
Applies to: ALL private lettings in a designated area — HMO or not.
The catch: Even a single-family house needs a selective licence if the council designated the area.
Issuing authority: The council (if designated).
Duration: Usually 5 years.
Cost: £400–£800.
Why: To regulate the private rented sector in high-deprivation areas with poor housing standards or antisocial behaviour.
It's mandatory in that area. Check your council's website for your postcode.
Quick Reference Table: Mandatory vs Additional vs Selective Licensing
| Regime | Applies to | Who can introduce it | Cost | Check your area |
|---|---|---|---|---|
| Mandatory HMO | 5+ unrelated people, shared facilities, any storey count | Law (Housing Act 2004) — all councils | £500–£1,200 (5 yrs) | Assume it applies to all HMOs |
| Additional HMO | 3–4 unrelated people (or council's threshold), shared facilities | Individual councils (discretionary) | £200–£600 (5 yrs) | Your council's website |
| Selective | ALL private lettings in a designated area (not just HMOs) | Individual councils (discretionary) | £400–£800 (5 yrs) | Your council's website (search postcode) |
How to Check If Your Property Needs a Licence
For England:
- Does it have 5+ unrelated people sharing facilities? = Mandatory HMO licence required.
- For 3–4 unrelated people, check your council's website for additional licensing (discretionary per council).
- Check if your postcode is in a selective licensing area (affects all lettings, not just HMOs).
Key point: Mandatory licence covers the property — you don't need both mandatory and additional.
Cost of HMO Licensing (England)
| Scheme | Cost (per cycle) | Renewal cycle |
|---|---|---|
| Mandatory HMO | £500–£1,200 | 5 years |
| Additional | £200–£600 | 5 years |
| Selective | £400–£800 | 5 years |

What You Must Do to Get a Licence
The Fit and Proper Person Test
You must be fit and proper: no unspent convictions, no housing breaches in past 6 years, no banning orders. The council does a background check. Spent convictions (Rehabilitation of Offenders Act 1974) don't count.
Safety Standards
Fire: Interlinked smoke alarms in all rooms, emergency lighting, fire doors.
Electrical: EICR before licence, then every 5 years.
Gas: CP12 annually.
Rooms: Minimum 6.51 m² (single) or 10.22 m² (double).
Amenities: One bathroom per 2 residents, one kitchen per 4, one toilet per 4.
Documentation Required
Application form, proof of identity, gas cert (CP12), EICR, EPC, insurance (must state HMO), floor plan, and proof of address. Some councils request tenancy agreements and deposit protection certificates.
How to Apply: Step-by-Step
- Gather documents: gas cert (CP12), EICR, EPC, insurance, floor plan, proof of identity/address. (4–8 weeks if starting from scratch.)
- Find your council's HMO licensing page. Most councils use online portals.
- Complete the application form and upload documents.
- Pay the fee. Non-refundable, but you can reapply if rejected.
- Wait for assessment: 6–12 weeks (longer in busy areas). Council may ask for clarifications.
- Receive licence. Valid 5 years. Renew 2–3 months before expiry.
If rejected: 28 days to appeal with additional evidence.
Penalties for Operating Without an HMO Licence
Criminal Penalties
Operating unlicensed in England:
- Unlimited fine (no cap)
- Criminal conviction
- Up to 12 months' imprisonment (extreme cases)
Recent fines: £40,000, £60,000, £100,000+. Councils actively prosecute.
Civil Penalties
Councils can issue a civil penalty notice (no court needed):
- Up to £30,000 per property
- No criminal conviction, but recorded
Rent Repayment Orders
The real sting. Tenants can claim up to 12 months' rent via the First-Tier Tribunal. Example: 5 students, unlicensed for 8 months at £2,000/month = £16,000 claimed. You can't evict to recover. Many tenants now check HMO status before signing.
Banning Orders
For serious or repeat breaches, councils can ban you from letting 1–5+ years. The ban appears on a national database, visible to mortgage lenders and estate agents, making it very hard to sell.
How SelfLet Helps
SelfLet's compliance engine automatically:
- Classifies each property by jurisdiction (England, Scotland, Wales) and HMO status
- Flags HMO thresholds — when occupancy changes trigger licensing requirements
- Tracks licence expiry dates and sends renewal reminders (12 weeks before expiry)
- Logs gas, EICR, and EPC renewal deadlines
- Alerts you to local authority licensing scheme changes
You still need to understand the rules. But SelfLet ensures you don't miss a renewal or forget which licences apply to your properties.
FAQs
Do I need both mandatory and additional licences?
No. Mandatory takes priority. One covers both.
What if the property drops below the HMO threshold?
Inform your council. You can't just stop — you must formally notify.
Can I appeal a rejected application?
Yes, within 28 days. Grounds: procedural errors, disputes over "fit and proper," or additional evidence.
Do I need to tell my mortgage lender?
Yes. Most mortgages restrict HMOs or require permission. Non-disclosure is a breach.
Self-managing an HMO without proper licensing is one of the fastest ways to lose money. A Rent Repayment Order wipes out months of profit. Licensing costs £500–£1,200 every 5 years. It's insurance.
