The Beginners Guide to Converting Your Property into an HMO

If you are considering converting your current property into an HMO to increase your rental income while providing more people with affordable accommodation, here’s how to do it.

Step 1: Plan First

Before you consider converting your property to an HMO, check that it is in the right location for an HMO. Ideally, your property should be in a busy student area or close to good transport connections to attract tenants.

Step 2: HMO Licensing

When you convert your property to an HMO, you’ll need an HMO licence to ensure that the property is safe and compliant.

We recommend that you contact your local council before planning your conversion to find out what you need to include in a compliant HMO property. 

If you want assistance with your application, you can talk to us about our HMO Licensing service. This service includes identifying what is needed in an HMO property for your council and applying for the local council’s property licensing scheme on your behalf.

Step 3: Minimum Room Size Requirements

Your HMO property will need to comply with the following minimum HMO room sizes:

  • No room less than 4.64 square metres can be used as sleeping accommodation. This size can only be used by one person aged under ten years.
  • A room size of 6.51 square metres minimum can only be used by one person aged over ten years.
  • A room size of 10.22 square metres minimum can only be used by two persons aged over ten years.

Depending on your local council, there may be other criteria to meet. We recommend that you speak to your local council before you plan your conversion.

Step 4: Converting to an HMO

The key areas to focus on in the conversion are providing sufficient space, a good layout, the right facilities, good furniture, and reliable appliances for three or more tenants from separate households to rent.

For example, if you own a three-bedroom house, this can typically be converted into six units with the following suggested conversions:

  • Adding a loft unit on the second (or third) floor 
  • Extending the rear of the property to add a unit (if the backyard is large enough)
  • Converting existing living areas into separate units
  • Installing ensuites and kitchenettes in all units
  • Converting the current kitchen to a communal kitchen and laundry
  • Converting the garage into an additional living space

You may need to move or construct walls to alter room sizes or add plumbing to create bathrooms. Whatever works are needed, we recommend engaging a professional. 

Remember, you may also need planning permission for the renovations.

Step 5: Safety Compliance

There are various compliance measures you’ll need to meet to let an HMO to potential tenants. This includes:

  • getting an annual gas safety certificate
  • installing the required number of smoke alarms and carbon monoxide detectors 
  • getting safety certificates for electrical appliances
  • keeping exits clear from obstructions and marking fire exits clearly
  • providing emergency lighting for fire safety
