Buying a buy-to-let property (BTL) through a limited company has become much more common in recent years, which is why SPV (Special Purpose Vehicle) mortgages keep popping up in landlord conversations. An SPV is a company created specifically to hold rental properties, and many lenders offer buy-to-let mortgages designed for this structure.
In this guide, we explain how SPV mortgages work, the tax implications, and when the extra admin may or may not be worth it.
Your home may be repossessed if you do not keep up repayments on your mortgage.
Most buy-to-let mortgages are not regulated by the FCA.

Tax treatment depends on your individual circumstances and may change in future. If you're considering purchasing property through a limited company or SPV, you should seek professional tax advice.
An SPV mortgage is a mortgage taken out by a limited company rather than by you personally. The company owns the property and the loan, though you'll usually give a personal guarantee.
You register the company at Companies House, the UK's official register of companies. You choose a SIC code, a Standard Industrial Classification code describing what the business does. For a property company, the right code signals to lenders that the SPV exists to hold and let property, not to trade in other areas.
Some lenders may decline an SPV mortgage application if the company's SIC codes do not clearly reflect property investment or letting activities.
That focused purpose is what makes lenders comfortable. They know the company isn't running any other businesses, which gives them a clearer view of what it does.
Read about limited company buy-to-let to understand how SPVs fit into the wider picture.
The choice between buying personally and through an SPV affects your taxes, costs, and mortgage options. Here's a side-by-side view.
Higher-rate taxpayers with a growing portfolio may find the SPV route worth considering, while basic-rate taxpayers with one or two properties may find the benefits more limited. Before making the call, consulting an accountant and a mortgage adviser together can give you the clearest picture.
An SPV pays corporation tax on rental profit rather than income tax. Corporation tax rates depend on company profits and current HMRC rules. Check the latest rates on GOV.UK or speak to a qualified tax adviser. For higher-rate taxpayers, that can mean a meaningful reduction in the tax bill on rental income. How much of a difference it makes depends on your overall tax position.
The bigger shift came with Section 24. Since these rules took effect, individual landlords can only claim mortgage interest relief as a basic-rate tax credit. A company, by contrast, can deduct its full mortgage interest costs before calculating its tax bill. When interest rates are higher, that difference can be significant.
There's also the question of what happens to the profit. Money left in the company, known as retained profit, is usually only subject to corporation tax until you take it out personally. That can be useful if you plan to reinvest the money rather than withdraw it straight away.
If you've lent your own money to the company, a director's loan account may allow you to take that money back out later without it being taxed again as income.
The tax benefits depend on your personal circumstances and the rules can change. If you're already a company director, read our guide to mortgages for limited company directors.
Imagine one rental property making £500 a month in profit after mortgage interest, which is £6,000 a year.
These figures are illustrative examples only and are not guaranteed outcomes and do not account for all taxes, costs or individual circumstances. Tax treatment depends on personal circumstances and may change in future. The amount of tax you may pay depends on your personal circumstances and HM Revenue and Customs (HMRC) rules, which can change.
An SPV isn't automatically the better choice. In several situations, the extra cost and admin may outweigh the benefits.
You'll also need to keep company records up to date and file annual accounts and confirmation statements with Companies House.
Weigh these against the wider costs of being a landlord before committing.
Setting up an SPV is usually more admin than anything particularly complicated.
Sort out your deposit figures early. Take a look at the deposit you will need for a BTL mortgage before you get too far into the process.
Lenders might look at your SIC codes when assessing an SPV mortgage application, so getting them right from the start can help avoid delays.
Many residential buy-to-let SPVs use 68209 as their primary SIC code. If you're unsure which codes fit your plans, an accountant can help. You can also check the latest classifications on the official SIC code list on Companies House.
SPV mortgage rates are often slightly higher than rates for buy-to-let properties owned personally, frequently around 0.1% to 0.5% higher. The lender pool is smaller, too. It has been growing as company ownership becomes more common, but you'll still have fewer options than landlords buying in their own name.
Typical lender requirements often include:
These are guides rather than fixed rules, since criteria vary by lender.
Because fewer lenders offer SPV mortgages, shopping around before settling on one lender can make a real difference.

SPV purchases usually pay the additional-property surcharge from the very first property. In England and Northern Ireland, that's currently 5% on top of standard rates. Scotland uses Land and Buildings Transaction Tax (LBTT), while Wales uses Land Transaction Tax (LTT), each with its own surcharge rules for additional properties.
If the SPV holds residential property worth over £500,000, the Annual Tax on Enveloped Dwellings (ATED) may also apply. That's a niche area, so speak to an accountant if it could affect you.
Watch out for transfer costs too: Moving a property you already own personally into an SPV may result in stamp duty and other tax liabilities depending on the circumstances. Professional tax advice should be sought before proceeding. That's the main reason most advisers suggest using an SPV for new purchases only, rather than moving existing ones across.

Quick answers to the questions landlords ask most often when considering an SPV.
Yes, the lender pool is more limited for first-time landlords, and many lenders want to see some property experience or at least a credible business case before they'll consider the application. A personal guarantee is almost always required. Some lenders also set a minimum personal income, so check the criteria before you apply.
In most cases, yes. A personal guarantee means that if the SPV can't keep up repayments, the lender can pursue the directors personally, including going after personal assets. This reduces the limited liability protection the company structure would otherwise give you. Most landlords accept it as part of the deal, but it's not something to take lightly. Make sure you understand exactly what you're agreeing to before you sign.
