Renting a Room in 2025/26: How the £7,500 Tax-Free Limit Works

With rising living costs and a shortage of rental accommodation in many parts of the UK, more homeowners are turning to spare rooms as a source of extra income. Whether you’re letting out a room to a lodger, offering short stays via Airbnb, or simply renting to a student or young professional, you may be eligible for tax-free rental income under the UK’s Rent-a-Room Scheme.

For the 2025/26 tax year, the Rent-a-Room allowance remains at £7,500 — offering a significant opportunity for individuals to generate income from their home without adding to their tax bill.

In this post, we explain how the scheme works, who qualifies, the conditions you must meet, and when it may be better to opt out and declare actual rental profits instead.

What Is the Rent-a-Room Scheme?

The Rent-a-Room Scheme is a voluntary tax exemption that allows individuals to earn up to £7,500 tax-free per year from letting furnished accommodation in their main home.

Key features:

  • The £7,500 allowance applies per property, not per person
  • If the home is jointly owned, the allowance is split equally (i.e. £3,750 each)
  • It applies to gross income, including rent, utilities, and any extras like meals or cleaning
  • You don’t need to register in advance — you claim the exemption via your Self Assessment tax return

Who Can Use the Scheme?

You can use the Rent-a-Room Scheme if:

  • You are an individual, not a company or partnership
  • You own or rent a property that is your main residence
  • You let out furnished accommodation in that home
  • The accommodation is used as a living space, not as an office or storage

This includes:

  • Taking in a lodger
  • Letting a room to a student
  • Hosting Monday-to-Friday lets
  • Short-term Airbnb-style lets in your home, as long as you live there during the letting period

What Doesn’t Qualify?

You cannot use the Rent-a-Room Scheme if:

  • You are letting out accommodation that is unfurnished
  • The income comes from a separate property, not your main home
  • You rent out a room in a business property
  • The room is let out to a business (e.g. for office use)
  • You let the whole property out and do not live there at the same time

Also, if you run a guest house or B&B as a trade, HMRC may consider that you are operating a business, not simply renting out a room.

How the £7,500 Limit Works

The exemption applies to total gross income from the let — including:

  • Rent
  • Utility contributions
  • Cleaning or laundry charges
  • Meals, if provided

If your gross income is £7,500 or less, the entire amount is tax-free, and you don’t need to declare it to HMRC (unless you already complete a tax return).

If your income is above £7,500, you can still:

  • Use the scheme, and pay tax only on the amount over £7,500
    OR
  • Opt out, and calculate your profit the usual way: income minus allowable expenses

Example 1: Income Below the Limit

You rent a room to a lodger for £500/month for 12 months = £6,000 total.

  • You live in the property and it’s your main home
  • You provide a furnished room and access to shared spaces

Result: You qualify for the exemption. The entire £6,000 is tax-free.

Example 2: Income Above the Limit — Use the Scheme

You earn £9,000 from letting a room.

  • You choose to use the scheme
  • You are taxed on the excess above £7,500

Taxable income = £9,000 – £7,500 = £1,500

You don’t deduct expenses — it’s a flat exemption.

Example 3: Income Above the Limit — Opt Out

You earn £9,000 from letting a room, but your expenses total £3,500 (utilities, repairs, cleaning).

You choose to opt out and calculate actual profit:

  • Income: £9,000
  • Expenses: £3,500
  • Taxable profit = £5,500

This is better than the flat £1,500 profit under the scheme in Example 2.

Key point: You can’t claim both — it’s either the £7,500 allowance or your actual profit after expenses.

Joint Owners and the £3,750 Rule

If you share ownership of the property with your spouse or another person, the allowance is split 50/50, unless you formally own different proportions.

So:

  • Each person can claim up to £3,750
  • Any income above this must be declared, and the same decision (scheme or opt out) must apply to both

Claiming Rent-a-Room Relief

If your gross rental income is under £7,500, and you don’t file a Self Assessment return, you don’t need to tell HMRC.

If you do complete a tax return, include the income and tick the box to use Rent-a-Room Relief.

If you choose to opt out and calculate actual profit, you’ll need to include full rental income and expenses in the property pages of your tax return.

Can You Use Rent-a-Room With Airbnb?

Yes — but only if you live in the property at the same time the room is let.

You cannot claim Rent-a-Room Relief if:

  • You let the entire property while you’re away
  • You rent a second home or holiday property

In those cases, the income is treated as normal property letting income, and expenses must be deducted to calculate profit. If you’re operating short-term lets as a business, you may also need to comply with local licensing laws.

Additional Considerations

  • Council Tax: Taking in a lodger may affect your council tax discounts. The 25% single person discount is lost if another adult moves in.
  • Mortgage or Lease Restrictions: Check if your mortgage lender or landlord allows subletting.
  • Insurance: Standard home insurance may not cover lodgers — always update your policy.
  • Licensing: Local councils may require a licence if you let rooms to multiple tenants (e.g. HMOs).

Summary

The Rent-a-Room Scheme remains one of the most generous tax exemptions available to UK homeowners — providing up to £7,500 per year tax-free for letting out furnished space in your main home.

You should consider using the scheme if:

 You let out a furnished room in your main home
 Your income is under or just above £7,500
 Your expenses are minimal
 You want simple, hassle-free tax treatment

You may want to opt out if:

 You have high expenses that reduce your taxable profit
 You rent out the entire property while away
 You let through a company or rent a second home

Used correctly, Rent-a-Room Relief can provide a tax-efficient way to boost income — whether you’re supplementing your pension, saving for a goal, or just making the most of unused space.
