SPV Property Companies: What They Are and Why Landlords Use Them

An SPV property company is a limited company set up for the single purpose of buying, holding and letting property, registered under a property-specific SIC code and carrying on no other trade. Landlords use one because buy-to-let lenders will generally not lend to a company that does anything else, and because a company deducts mortgage interest in full while an individual landlord cannot. For a growing portfolio, property company incorporation is the landlord decision with the largest effect on long-term returns. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, structures these companies for landlords nationwide. This article covers what makes a company an SPV, why lenders insist on it, what it saves on real figures, what it costs to run, and which portfolio sizes justify it.

Key Takeaways

• An SPV property company is a limited company incorporated solely to hold and let property, typically registered under SIC code 68209 for letting and operating of own or leased real estate.
• Most limited company buy-to-let mortgage products are available only to SPVs, because lenders will not accept the trading risk attached to a company with other activities.
• A company deducts mortgage interest in full against rental profit, while an individual landlord's relief is capped at a 20% basic rate tax credit under the Section 24 rules.
• Corporation tax for 2026/27 is 19% on profits up to £50,000 and 25% above £250,000, with marginal relief producing an effective 26.5% rate in between.
• A company buying a residential property pays the same 5% higher rates for additional dwellings surcharge as an individual buying an additional property, so an SPV purchase costs no extra stamp duty land tax.
• Extracting profit costs dividend tax at 10.75%, 35.75% or 39.35% in 2026/27 after a £500 allowance, so the structure works best where profits are retained.

What makes a company an SPV rather than an ordinary limited company?

An SPV is defined by what it does not do: it holds and lets property and carries on no trading activity, signalled to lenders through its SIC code and its accounts. There is no separate legal category of SPV in the Companies Act 2006. A landlord incorporates a private company limited by shares, then restricts its activity.

Three SIC codes are recognised by lenders: 68100 for buying and selling of own real estate, 68209 for other letting and operating of own or leased real estate, and 68320 for management of real estate on a fee or contract basis. Most landlords use 68209, and adding an unrelated code or later filing accounts showing consultancy income can put existing lending in breach of covenant. The company must also behave as a separate legal person: rent into the company account, expenses paid by the company, withdrawals recorded as salary, dividend or director's loan repayment.

Why do buy-to-let mortgage lenders insist on an SPV?

Lenders require an SPV because a single-purpose company gives a clean security position, with no trading creditors, no employment liabilities and no operational risk competing with their charge over the property. A company also running a building firm could fail for reasons unconnected with the rent, leaving the lender as one creditor among many.

Borrowing options therefore narrow sharply outside the structure. Most limited company buy-to-let products specify an approved SIC code, and the few lenders considering a trading company price the risk higher. Rates sit modestly above equivalent personal products, with higher arrangement fees, and directors should expect to give personal guarantees.

How much tax does an SPV property company actually save?

The saving comes from full interest deductibility and the gap between corporation tax and higher rate income tax. Section 24 restricts an individual's finance cost relief to a 20% credit, so a higher rate taxpayer effectively pays tax on mortgage interest. A company does not.

Worked example. A landlord buys a £300,000 rental property producing £18,000 of rent, with £9,000 of mortgage interest and £2,500 of other allowable costs. Held personally by a 40% taxpayer, taxable profit is £15,500 because the interest is not deductible, giving income tax of £6,200 less a £1,800 finance cost credit, so £4,400 is payable against cash profit of £6,500. The landlord keeps £2,100. Held in an SPV, taxable profit is £6,500 and corporation tax at 19% is £1,235, leaving £5,265 retained, an annual advantage of £3,165 on one property.

Stamp duty is neutral on a new purchase: the company pays £5,000 of standard SDLT on £300,000 plus the 5% surcharge of £15,000, exactly what an individual buying an additional property would pay.

What does an SPV cost to run and where does it go wrong?

An SPV adds roughly £900 to £1,800 a year of compliance cost for a small portfolio, and creates a second tax charge on money the landlord needs personally. Annual accounts, a corporation tax return, a confirmation statement and a separate bank account are all required.

Extraction is the real constraint. Taking £20,000 as a dividend in 2026/27 costs a higher rate taxpayer 35.75% above the £500 allowance, around £6,972, erasing several years of corporation tax advantage. Repaying a director's loan created when the landlord lent in the deposit is tax-free and should be used first.

Two traps deserve attention in any landlord incorporation guide UK landlords rely on. A company letting to connected persons rather than at arm's length may lose the 19% small profits rate as a close investment-holding company, and where the landlord controls other companies the £50,000 and £250,000 thresholds are divided between them.

Which landlords should use an SPV?

Use an SPV where you are a higher or additional rate taxpayer, the property is mortgaged, and you intend to retain profits to buy more. Stay in personal ownership where none of those apply.

A landlord with one or two unmortgaged properties, or income within the basic rate band, generally gains nothing. A higher rate taxpayer with three to five geared properties who plans to keep buying should hold new acquisitions through an SPV, leaving existing properties alone to avoid capital gains tax and stamp duty. A landlord with six or more geared properties, taxed at 40% or 45% and reinvesting, has the strongest case.

Frequently Asked Questions

What SIC code should a property SPV use?

Most landlord SPVs use SIC code 68209, other letting and operating of own or leased real estate, which covers holding residential property for rent. Code 68100, buying and selling of own real estate, suits companies that may trade or develop. Buy-to-let lenders check the code at Companies House, so it should be set correctly at incorporation.

Can I move my existing buy-to-let properties into an SPV?

Yes, but the transfer is treated as a sale at market value, triggering capital gains tax for you and stamp duty land tax for the company, even where no money changes hands. Incorporation relief under section 162 TCGA 1992 can defer the capital gain where the portfolio amounts to a genuine business, though the conditions are demanding.

How many properties do I need before an SPV is worth it?

There is no fixed number. The structure is driven by your marginal tax rate, how much of the portfolio is mortgaged, and whether you need the rental income to live on. A higher rate taxpayer with geared property who reinvests profits can benefit from the first purchase, while a basic rate taxpayer with unmortgaged property rarely does.

Do I pay tax twice on money taken out of an SPV?

Effectively yes. The company pays corporation tax on rental profit, and you pay dividend tax at 10.75%, 35.75% or 39.35% in 2026/27 on what you withdraw above the £500 dividend allowance. Repaying a director's loan is not taxable, so deposits lent into the company should be drawn back before dividends are declared.

How Blue Tick Can Help

Blue Tick Accountants sets up property SPVs with the right SIC code, share structure and director's loan documentation, so that lending and future extraction are not compromised at incorporation. Where an existing portfolio is involved, the analysis extends to incorporation relief, stamp duty exposure and timing. Head to our website and book a meeting now.

Conclusion

An SPV is not a loophole, it is a change of ownership that shifts rental profit from a 40% or 45% income tax regime into a 19% or 25% corporation tax regime, at the price of a second charge whenever money comes out. That trade favours landlords building a portfolio and disadvantages those living on the rent. Decide which you are before incorporating, and put new purchases inside the company from day one rather than moving them later.
