What it is
A self-contained annexe, outbuilding or garden room at your home, furnished for short self-catering stays. Guests agree to a clear no-smoking rule when they book.
Your first three steps
- Check with your mortgage lender, landlord or council whether you can let the space, and whether planning permission is needed
- Furnish and photograph the space, then work out a nightly rate by looking at similar lets nearby
- List it on one or two booking sites with a clear no-smoking rule and house rules, then ask early guests for reviews
Who pays
Holidaymakers, visiting relatives, walkers and cyclists, and people travelling for work or events nearby.
How it makes money
A nightly or weekly rate per stay, often with a cleaning fee. Rates usually go up in school holidays and around local events.
Skills that help
- Friendly, clear communication with guests
- Keeping a space spotless between stays
- Basic organising and booking admin
Watch out for
- Insurance that covers paying guests, as standard home insurance may not
- Gas, electrical and fire safety checks and working smoke and carbon monoxide alarms
- Planning permission, council tax or business rates, and your mortgage or lease terms, so check with your council and lender
- Short-term let rules differ across the UK (Scotland has a licensing scheme), so check what applies where you live
- Tax on rental income, so speak to an accountant or HMRC about what you need to report
- Smoking rules only work if clearly stated and enforced, so set out any cleaning charge in your booking terms
