Frequently Asked Questions

What is the Rent-a-Room scheme?

The Rent-a-Room scheme lets you earn up to £7,500 per year tax-free from renting a furnished room in your main home as a lodger. If joint owners, the threshold is £3,750 each.

Do I need to declare Rent-a-Room income?

If your lodger income is below £7,500 you don't need to declare it. If above, you must file a self assessment return and can elect to use the Rent-a-Room method (income minus £7,500 threshold) or actual expenses method.

Can landlords use Rent-a-Room for buy-to-let?

No — Rent-a-Room only applies to your main home (the property you live in). If you let a separate property, normal property income rules apply.

What counts as furnished accommodation?

The room or rooms must be furnished (basic furniture provided). The lodger lives in your home — they are not a tenant in a separate dwelling.

Does the Rent-a-Room threshold include bills?

Yes — if you charge the lodger a single amount covering rent and utilities/meals, that total counts towards the £7,500 threshold.

Can I use Rent-a-Room if I'm renting my home?

Yes — tenants can use the scheme if their tenancy agreement doesn't prohibit subletting. Always check your tenancy agreement.

Do B&B or short-let income qualify?

Yes — short-term lodgers (e.g. through Airbnb) in your main home qualify for Rent-a-Room. However, HMRC guidance says each short-let property is treated separately.

What happens if my income exceeds £7,500?

You have two options: (1) pay tax on income above £7,500 (Rent-a-Room method); or (2) pay tax on profit after actual expenses (standard method). Choose whichever gives lower tax.

Does Rent-a-Room affect Housing Benefit?

Rent-a-Room income is generally disregarded for Housing Benefit and Universal Credit housing costs. However, check with your council.

Can I claim mortgage interest relief alongside Rent-a-Room?

No — if you elect for Rent-a-Room relief, you cannot also claim actual expenses including mortgage interest. The election means you only pay tax on income above the threshold.

Is Rent-a-Room income subject to NI?

No — Rent-a-Room income is rental income, not trading income, so NI doesn't apply.

Can two people share the Rent-a-Room scheme for the same property?

If you jointly own and live in the property, each gets a £3,750 threshold (total £7,500). You cannot both claim £7,500 each.
