What it is

You let one or two spare rooms in the home you live in, either to longer-term lodgers or to short-stay guests such as visiting workers, students or travellers. You provide a clean, safe room, shared facilities and clear house rules.

Your first three steps

  1. Check local room prices on listing sites to set a sensible rate
  2. Ask your landlord, mortgage lender and home insurer if lodgers are allowed
  3. Prepare the room, take good photos and write a clear advert with house rules
Who pays

Lodgers, contractors and workers on short assignments, students, and travellers or visitors to your area.

How it makes money

A weekly or monthly rent for lodgers, or a nightly rate for short stays. Bills can be included in the price or charged separately.

Skills that help
  • Friendly and trustworthy host
  • Keeping a home clean and tidy
  • Clear communication and setting house rules
Watch out for
  • Permission from your landlord, mortgage lender or council, and whether your home insurance covers lodgers or guests
  • Whether the Rent a Room scheme applies to your tax situation, check with HMRC
  • Smoke and carbon monoxide alarms, gas and electrical safety, check what applies to your home
  • Short-term guests may need extra checks such as fire safety and, if you serve breakfast, food business registration with your council
  • Sharing your home means less privacy, so check references and agree rules before anyone moves in
