HMO Guide

Maximise Rental Income with Shared Living

Houses in Multiple Occupation (HMOs) are one of the most profitable ways to invest in property — but they come with additional responsibilities and regulations.

At Proper Rooms, we help landlords navigate the process safely, legally, and profitably.

What is an HMO?

A property is classed as a House in Multiple Occupation (HMO) if:

  • It is rented to 3 or more people
  • The tenants form 2 or more households
  • They share facilities such as a kitchen or bathroom

Large HMO

A property is a large HMO if:

  • 5 or more tenants live there
  • They form more than one household

👉 Large HMOs require a mandatory licence

Why Choose an HMO Strategy?

Higher Rental Income

Renting by the room typically generates significantly more income than letting as a whole property.

Reduced Void Risk

If one tenant leaves, you still receive income from the others.

Strong Demand

High demand in cities like London from:

  • Young professionals
  • Students
  • Key workers

👉 HMOs are ideal for maximising yield in high-demand areas.

HMO Licensing & Legal Requirements (UK)

Operating an HMO requires strict compliance with UK regulations.

You May Need a Licence If:

  • Your property is a large HMO (5+ tenants)
  • Your local council requires additional licensing

Key Requirements Include:

  • Minimum room sizes
  • Adequate kitchen & bathroom facilities
  • Fire safety systems (alarms, fire doors)
  • Safe escape routes
  • Waste disposal arrangements

👉 Rules vary by local authority — getting it wrong can be costly

Safety & Compliance Essentials

To legally rent out an HMO, you must ensure:

  • Gas Safety Certificate (CP12) – renewed annually
  • Electrical Safety (EICR) – every 5 years
  • Smoke & heat alarms installed and working
  • Fire doors where required
  • Furniture compliance with fire regulations
  • Right to Rent checks for all tenants

👉 Non-compliance can lead to fines or rent repayment orders

Is Your Property Suitable for an HMO?

Not every property works well as an HMO. Key factors include:

  • Property size and layout
  • Number of bedrooms possible
  • Location and tenant demand
  • Planning restrictions (Article 4 areas)
  • Parking and transport links

👉 We can assess your property and advise on viability
