With mortgage rates high, living costs stubborn and a nationwide shortage of affordable rental stock, a spare room has become one of the most valuable and underused assets in the average UK household. The Rent a Room Scheme lets you earn up to £7,500 a year completely tax-free by letting furnished accommodation in your main home.
Whether you’re taking in a lodger, hosting a student, or renting a room on Airbnb while you live in the property, this HMRC-backed relief is one of the most generous tax exemptions available to UK homeowners and tenants. This guide walks you through how the scheme works in the 2025/26 tax year, who qualifies, what’s changed, and when it might actually be smarter to opt out.
What is the Rent a Room Scheme?
The Rent a Room Scheme is a voluntary tax exemption that allows individuals to receive rental income tax-free from letting furnished accommodation in their only or main home. For the 2025/26 tax year (6 April 2025 to 5 April 2026), the tax-free threshold is £7,500 per property or £3,750 each if the income is shared with someone else, such as a spouse or joint owner.
The scheme is set out in Part 7 of the Income Tax (Trading and Other Income) Act 2005 and explained in HMRC’s Helpsheet HS223. Crucially, if your gross receipts from letting a room stay under the threshold, the exemption is automatic you don’t need to tell HMRC, file a return just for this, or do anything at all.
Who can use the Rent a Room Scheme?
You can use the scheme if you are:
- An owner-occupier letting a furnished room in your main home
- A tenant sub-letting a room (provided your lease allows it)
- A resident letting multiple rooms, a bedsit, or even a whole floor, as long as you still live there
- A host using platforms like Airbnb, SpareRoom or Lodger.com for stays within your main home
You cannot use the scheme if:
- The accommodation is in a property that is not your main or only residence
- The home has been converted into separate self-contained flats
- The space is let as unfurnished accommodation
- The room is used as an office or for business (incidental home working by a lodger in the evenings or weekends is fine)
- You let the whole property while you are away (for example on holiday) the scheme needs you to be living there at the same time
- You let through a limited company
How the £7,500 threshold works in practice
The £7,500 allowance covers the gross receipts from letting not your profit. That means it includes the rent itself, plus any payments you receive for meals, cleaning, laundry, bills or other services rolled into the charge. If your lodger pays £150 a week for the room plus £25 a week toward heating and Wi-Fi, all £175 a week counts toward the threshold.
The threshold is also fixed regardless of how long you let. Letting a room for just three months at £600 a month gives you £1,800 comfortably under £7,500. Letting at £700 a month for the full year gives you £8,400 over the limit, and now you have a decision to make.
Where two or more people share the letting income (for example a married couple who jointly own the home), the threshold drops to £3,750 each. The total household relief stays at £7,500 it is simply split.
What happens if you earn more than £7,500?
If your gross rental receipts exceed the threshold, you must complete a Self Assessment return. You then have two options.
Method A Pay tax on actual profit
You declare the full rental income and deduct allowable expenses (a fair share of utilities, insurance, cleaning, wear and tear on furnishings, etc). You pay tax on the net profit at your marginal income tax rate.
Method B Pay tax on gross receipts above £7,500
You ignore your actual expenses entirely and simply pay tax on everything above £7,500. So on £10,000 of gross receipts, you pay tax on £2,500.
You must actively tell HMRC on your tax return if you want to use Method B. You can switch between methods year to year, provided you notify HMRC each time within the time limit usually the 31 January Self Assessment deadline following the end of the relevant tax year.
Which method is better?
As a rough rule: if your deductible expenses are less than £7,500, Method B (the scheme) will give you more relief. If your expenses are more than £7,500, you will almost certainly be better off opting out and using the standard property income rules under Method A.
Worked example: choosing between Method A and Method B
Sarah rents out a furnished double room in her Manchester home for £850 a month. Her lodger also pays £50 a month toward bills. Gross annual receipts: £10,800.
Sarah’s deductible expenses a fair share of utilities, council tax, insurance, and wear-and-tear allowance on the room come to £2,200 a year.
Method A (actual profit): £10,800 − £2,200 = £8,600 taxable profit. Method B (Rent-a-Room): £10,800 − £7,500 = £3,300 taxable profit.
Sarah’s expenses are well below £7,500, so Method B saves her tax on £5,300 of income compared with Method A. If she’s a basic-rate taxpayer that’s around £1,060 saved a year; at higher rate, roughly £2,120.
Now flip it. If Sarah had £8,000 of genuine running costs (say she rented the whole place out over summer and paid cleaning, platform fees, and higher utility bills), Method A’s actual-profit calculation would leave only £2,800 taxable — better than Method B’s £3,300. In that scenario, opting out makes sense.
Rent a Room Scheme and Airbnb in 2025/26
Airbnb and other short-stay platforms are fully within scope of the Rent a Room Scheme provided you are letting a room (or rooms) inside your main home and living there at the same time. The £7,500 allowance applies to your gross receipts from the platform before Airbnb’s service fee is deducted.
A few points that often trip hosts up:
- The allowance does not apply to letting an entire separate dwelling that is taxed as ordinary property income.
- The Furnished Holiday Let (FHL) regime ended from April 2025, so the special CGT and pension-contribution benefits that previously attached to FHLs no longer exist. For most Airbnb hosts operating in their main home, this makes Rent a Room Relief even more attractive by comparison.
- You cannot claim Rent a Room Relief and the £1,000 property allowance against the same income it’s one or the other.
- London hosts should remember the 90-night short-term let cap under the Deregulation Act 2015 it is a separate planning rule, not a tax rule, but breaching it can cost more than any tax saved.
Rent a Room Scheme for tenants
Many tenants do not realise the scheme applies to them too. If you rent your home and sub-let a room to a lodger, you can claim Rent a Room Relief on the receipts provided your tenancy agreement allows sub-letting and your landlord has consented. Breaching your lease to take in a lodger is risky and may get you evicted, regardless of what HMRC thinks about the income.
Impact on benefits, council tax and mortgage
The Rent a Room Scheme is a tax relief only. It does not insulate you from knock-on effects elsewhere:
- Mortgage: owner-occupiers should get written consent from their lender before taking in a lodger. Some mortgage products restrict this.
- Home insurance: notify your insurer. Taking in a lodger without disclosure can invalidate cover.
- Council tax: if you’re a single adult claiming the 25% single person discount, taking in a lodger may end that discount.
- Means-tested benefits: rental income can affect Universal Credit, Housing Benefit and Pension Credit calculations — even when it is tax-free.
- Capital gains tax (CGT): letting a room in your main home usually does not disturb Private Residence Relief on the let area, provided you and the lodger share living space — but exclusive, self-contained lets over longer periods should be reviewed.
Rent a Room vs the £1,000 Property Allowance
People often confuse the Rent a Room Scheme with the £1,000 property allowance. They are different reliefs.
The property allowance gives a flat £1,000 tax-free amount on any property income — typically aimed at casual lets, storage space, driveway rentals and the like. You cannot use both against the same income. For anyone letting a room in their main home, the Rent a Room Scheme’s £7,500 allowance is dramatically more generous and almost always the right choice.
Frequently asked questions
Do I have to tell HMRC if I earn under £7,500? No. If your gross receipts from letting a room in your main home are below the threshold, the exemption is automatic and no reporting is needed unless you already complete a Self Assessment return, in which case you tick the box to claim the relief.
Can spouses both claim £7,500? No. If two or more people share the income from the same property, the allowance is split — typically £3,750 each. The total household relief remains £7,500.
Can I claim expenses if I use the scheme? No. Method B gives a flat £7,500 allowance with no expense deduction. If your expenses are high, consider opting out and using Method A instead.
Does letting a room affect Capital Gains Tax when I sell? Generally, no if the lodger shares living accommodation with you (kitchen, bathroom, living room), Private Residence Relief should continue to apply. Self-contained lets carved out of the home over longer periods need specialist review.
Can I create a loss under the scheme? No. HS223 confirms that if you’re within the scheme (under the threshold, or using Method B), you cannot create a loss. To use rental losses, you must opt out and use Method A.
Does the scheme cover hosting international students through an agency? Yes, provided the student stays in your main home as a lodger. Homestay placement payments often include meals and services — all of which count toward the £7,500 limit.
Getting the most out of Rent a Room Relief
The Rent a Room Scheme is one of the most taxpayer-friendly reliefs in the UK system — up to £7,500 a year tax-free, with zero paperwork if you stay under the threshold. But the right choice between opting in and opting out comes down to the numbers in your specific situation: how much you charge, what your costs are, whether ownership is shared, and how the income interacts with other allowances and benefits.
