Liverpool HMO Licence: Mandatory Requirements, Fees and Room Sizes

When a Liverpool Property Needs a Mandatory HMO Licence

A house in multiple occupation (HMO) needs a mandatory licence under Part 2 of the Housing Act 2004 if it meets all of these criteria:

• Five or more people live in the property
• Those people form two or more separate households (family units)
• They share at least one basic amenity — a kitchen, bathroom, or toilet
• The property is their main residence
• At least one occupant pays rent

This applies across the whole of Liverpool — every ward, not just the 39 covered by selective licensing. There's no geographic boundary. If your property qualifies as a large HMO anywhere within Liverpool City Council's administrative area, it needs a mandatory licence.

A common point of confusion: Liverpool does not run an additional HMO licensing scheme. That means smaller shared houses (three or four unrelated occupants) don't need an HMO licence. They may, however, need a selective licence if the property sits in one of the 39 designated wards.

Minimum Room Sizes

National regulations set mandatory minimum sleeping room floor areas for licensed HMOs. These are strict statutory minimums — not targets — and Liverpool enforces them:

• Single occupant (age 10+): 6.51 m²
• Two occupants sharing (age 10+): 10.22 m²
• Single occupant (under 10): 4.64 m²
• Any room under 4.64 m²: cannot be used as sleeping accommodation at all

Floor area is measured excluding any part of the room where the ceiling height falls below 1.5 metres. That attic conversion with sloped ceilings may look spacious, but the usable area for licensing purposes could be significantly less than the estate agent's floor plan suggests.

The council checks these measurements during inspections. A room that doesn't meet the minimum can't be counted toward occupancy, which may change which licence type your property needs — or whether the licence is granted at all.

HMO Licence Fees

Liverpool's mandatory HMO fees are substantially higher than selective licensing fees and scale with occupant count:

• Up to 5 occupants: £1,328 (£489.10 Part 1 + £838.90 Part 2)
• 6 occupants: £1,449
• 7 occupants: £1,570

HMO licences use a separate fee schedule from selective licences; check Liverpool City Council's current HMO fee table for any applicable discounts. The two-part structure works the same way — Part 1 at application, Part 2 on grant — and the Part 1 payment is generally non-refundable, subject to the council's listed refund exceptions for duplicate applications, exempt properties, and applications submitted under the wrong type.

Fire Safety and Management Standards

HMO licensing carries heavier safety obligations than selective licensing. On top of the standard gas, EICR, and EPC certificates, HMO landlords must provide:

• Mains-powered, interlinked smoke alarms conforming to BS 5839-6, covering escape routes and high-risk rooms
• Heat alarms in kitchens
• Fire doors with smoke seals and self-closing devices on all habitable rooms leading to protected escape routes
• Emergency escape lighting where the escape route is complex
• A written fire risk assessment reviewed annually
• Scaled floor plans showing room dimensions, uses, and fire escape routes

Liverpool also enforces waste management requirements under the Management of HMOs Regulations 2006. You need adequate wheelie bins (purple refuse, blue recycling, green garden waste in Liverpool's system) and written collection schedule instructions for occupants. Refuse accumulation in front yards or alleyways is a licence condition breach.

HMO Licensing vs Selective Licensing

The two schemes serve different property types and carry different obligations:

A property occupied by five or more people in two or more households with shared facilities needs a mandatory HMO licence — regardless of ward. A property let to a single family, a couple, two sharers, or three to four unrelated people in a designated ward needs a selective licence. A property can't hold both simultaneously; mandatory HMO licensing takes precedence.

HMO licences cost more, require additional documentation (floor plans, fire risk assessments), and carry stricter physical standards. But the enforcement penalties are identical: civil penalties of up to £40,000 for offences committed on or after 1 May 2026, plus rent repayment orders of up to 24 months' rent for qualifying offences committed on or after that date. Earlier RRO offences remain subject to the previous one-year cap.

The Article 4 Trap

Securing an HMO licence from Liverpool's housing department doesn't give you planning permission. Liverpool enforces Article 4 directions across wide areas of the city, removing permitted development rights for converting a C3 dwelling to a C4 small HMO. Large HMOs (seven or more occupants) are classified as Sui Generis and always require full planning permission, anywhere in the city.

Operating as an HMO without planning consent triggers a separate enforcement track from the council's planning team. They can issue enforcement notices requiring you to revert the property to single-family use — and having a valid HMO licence won't stop that.
