Take in a lodger in your own UK home and keep the rent tax-free up to the Rent a Room Scheme's annual limit.
This is a specific UK HMRC tax scheme with no direct equivalent - other countries have their own live-in landlord tax treatments, generally less generous.
What does work here: Turo car-sharing, Real estate wholesaling
Why that grade The tax-free threshold and scheme mechanics are official HMRC/gov.uk policy, not a third-party estimate. Course-seller index 0/10.
Figures are researched estimates, not guarantees. Check local rules before you trade.
A spare room is otherwise unused space, and a live-in landlord offering a room with shared facilities meets real demand from people who want cheaper, more flexible accommodation than a full flat.
Officially tax-free up to 7,500 GBP/year (or 3,750 GBP each if income is shared, e.g. with a partner) under HMRC's Rent-a-Room Scheme; actual room rents vary hugely by city, from a few hundred pounds a month in smaller towns to over 1,000 GBP/month in central London.
Any UK homeowner or tenant (with permission) with a genuine spare room who's comfortable sharing their home with another person.
Anyone whose mortgage lender, landlord or insurer explicitly restricts lodgers, or anyone genuinely uncomfortable with a stranger sharing their living space.
You're sharing your actual home with a stranger, and a lodger has fewer legal protections than a full tenant but you also have fewer formal eviction rights than a landlord-tenant scenario would give you - check mortgage lender and, if you rent, your own landlord's permission before taking someone in.

Watch out: This is the only real way this idea goes wrong - always check first.
Get the room ready and agree a licence to occupy, not a full tenancy agreement, with the lodger.
Done when The room is ready and you have a signed licence-to-occupy (not tenancy) agreement with your lodger before they move in.
Watch out: A licence gives both parties less formal legal protection than a tenancy - understand what that means before signing.
The rest of the playbook: what to charge, what you need in place before you take money, where the first customers come from, and what each step costs.
