How to Set Up a Property SPV Limited Company in the UK
More than 43% of new buy-to-let purchases in the UK now go through a limited company rather than an individual's own name. A structure that used to be a niche choice for large portfolio landlords is now close to the default for anyone buying seriously — and the reason is almost entirely tax, not liability protection.
Section 24 removed higher-rate mortgage interest relief for landlords who own property personally, back in 2020. A limited company was never affected by that change — it can still treat 100% of its mortgage interest as a normal business expense before tax. For a higher-rate taxpayer with significant mortgage debt, that difference alone is often worth thousands of pounds a year.
This guide covers what a property SPV actually is, exactly what it costs to set one up in 2026 (this changed recently — more below), which SIC code to register under, the real tax case for and against, and what happens once the company exists.

What Is a Property SPV and Why Do Investors Use One?
SPV stands for Special Purpose Vehicle. It sounds like a distinct legal category, but it isn't — an SPV is simply an ordinary private limited company registered at Companies House, set up with the single purpose of buying, holding, and letting investment property. "SPV" is a description of what the company does, not a special type of company you tick a box for.
The reason investors use one comes down to how mortgage interest is treated for tax purposes. A landlord who owns property personally gets only a 20% tax credit on mortgage interest, regardless of their actual income tax rate — a legacy of Section 24. A limited company faces no such restriction: mortgage interest is deducted in full as a business expense before Corporation Tax is calculated on the remaining profit. For a 40% or 45% taxpayer with meaningful borrowing, that gap compounds every year the mortgage exists.
How Much Does It Cost to Set Up a Property SPV in 2026?
| Item | Cost |
|---|---|
| Companies House online registration (as of 1 February 2026) | £100 |
| Companies House paper registration | £40 |
| Formation agent bundle (agent fee + VAT + Companies House fee) | from ~£103 all-in |
| Registered office address (if not using your own address) | £30–£100/year |
| Ongoing: accountancy | £500–£1,500/year |
| Ongoing: Companies House confirmation statement | £34/year (online) |
| Ongoing: business bank account | £0–£120/year |
There's a genuinely important date here: Companies House raised its digital company registration fee from £50 to £100 on 1 February 2026. If you've read older guides quoting £50, or even the £12 figure from a few years before that, they're out of date — the government fee alone is now £100, before any formation agent's own service charge is added on top.
Choosing the Right SIC Code for a Property SPV
Every UK company registers under one or more SIC (Standard Industrial Classification) codes, which tell Companies House — and, indirectly, mortgage lenders — what the company actually does. Getting this wrong doesn't stop you registering, but it can cause friction later when a lender reviews your application.
For a property SPV, two codes matter:
68100 — Buying and selling of own real estate. Appropriate for a company that trades or flips property rather than holding it long-term as a rental.
68209 — Other letting and operating of own or leased real estate. Appropriate for a standard buy-to-let or portfolio-holding company — this is the code most specialist BTL lenders expect to see.
If your plan is straightforward buy-to-let, register under 68209. You can register up to four SIC codes, and many BTL SPVs register both 68100 and 68209 to cover an eventual sale as well as ongoing letting. If you're unsure, ask your mortgage broker which code their preferred lenders expect before you complete registration — it's much easier to get right at incorporation than to explain to an underwriter later.
Step-by-Step: How to Register a Property SPV
- Choose and check a company name at Companies House — it must be unique and follow naming conventions.
- Choose your SIC code(s) — 68209 for buy-to-let, optionally alongside 68100.
- Appoint at least one director and one shareholder — these can be the same person.
- Provide a registered office address — this must be a physical UK address; a PO Box alone is not accepted.
- Prepare Articles of Association — a standard template is sufficient for most straightforward property SPVs.
- Register online (£100) or by paper (£40) — online registration typically completes within 24 hours.
- Register for Corporation Tax with HMRC within 3 months of the company starting to trade — in practice, from the point it starts receiving rental income or otherwise trading.

Should You Buy in Personal Name or Through an SPV? (The Tax Comparison)
This is the question that actually drives the SPV decision, and it has nothing to do with Stamp Duty — SDLT is identical whether you buy the same property personally or through a company, at least below £500,000 (see our full SDLT guide for the £500,000 cliff edge above that threshold).
The real difference is income tax versus Corporation Tax:
Personal name: mortgage interest gets only a 20% tax credit, applied regardless of your marginal income tax rate. A 40% taxpayer paying £10,000 a year in mortgage interest gets a £2,000 credit — not £4,000.
SPV: mortgage interest is a fully deductible business expense before tax. Corporation Tax then applies at 19% on profits up to £50,000, 25% above £250,000, with marginal relief in between.
As an illustration: a higher-rate taxpayer with £40,000 in rental income and £20,000 in mortgage interest costs can see a £4,000–£8,000 difference in annual tax liability between personal-name and SPV ownership. The exact figure depends entirely on your income, gearing, and portfolio size — model your own numbers rather than relying on a generic example.
The Catch: You Almost Never Want to Transfer an Existing Property Into an SPV
This is the point that catches out investors who've already built a personal-name portfolio and then discover the SPV tax case.
Moving a property you already own personally into a company — even one you also own — is treated by HMRC as a sale. That triggers:
- SDLT at the standard second-property rates, calculated again as if it were a fresh purchase
- Capital Gains Tax on the personal disposal, based on the gain since you originally bought it
- Full conveyancing costs, exactly as if you were selling to an unconnected buyer
There is a narrow exception: Incorporation Relief under Section 162 of the Taxation of Chargeable Gains Act 1992 can defer the CGT charge, but only where the properties constitute a genuine business — generally requiring active, hands-on management across a real portfolio, not passive letting of one or two properties. Whether it applies to your specific situation is a specialist question, not a DIY judgement call.
The practical takeaway: SPVs make the most sense for new purchases. Moving property you already hold personally into a company is rarely worth the combined SDLT and CGT hit unless Incorporation Relief genuinely applies.

Getting a Mortgage for Your SPV
SPV buy-to-let mortgage rates typically run 0.2–0.5 percentage points above equivalent personal-name BTL rates, and deposit requirements are usually 20–25% or more.
Almost every lender in this space will require a personal guarantee from the company's directors. This is worth sitting with for a moment: despite the limited company structure, directors remain personally liable if the company defaults on the mortgage. The "limited liability" of an SPV protects you from most business risks, but not typically from the mortgage itself.
Not every high street lender offers limited company BTL mortgages — this is a specialist corner of the market, so use a broker who works with SPV BTL specifically rather than a generalist mortgage adviser.
Ongoing Responsibilities After Incorporation
Setting up the company is the easy part. Once it exists, you're on the hook for:
- Corporation Tax registration with HMRC within 3 months of starting to trade
- An annual Confirmation Statement filed with Companies House (£34 online)
- Annual accounts filed with Companies House and a Corporation Tax return filed with HMRC
- Proper business records — a separate business bank account isn't strictly mandatory, but it's strongly recommended and most accountants will expect it
Frequently Asked Questions
Is an SPV the same as a normal limited company?
Yes. There's no special legal category called "SPV" — it's an ordinary private limited company. "SPV" simply describes a company set up with a single, narrow purpose (holding and letting investment property), rather than trading multiple business lines.
What SIC code should I use for a buy-to-let company?
68209 (other letting and operating of own or leased real estate) is the code most specialist BTL lenders expect for a standard rental-holding company. 68100 (buying and selling of own real estate) suits a trading or flipping company. Many investors register both.
How much does it cost to set up a property SPV in 2026?
The Companies House government fee is £100 for online registration (raised from £50 on 1 February 2026), or £40 by paper. A formation agent bundle including that fee typically starts from around £103 all-in.
Can I move my existing rental property into an SPV without extra tax?
Generally no — it's treated as a sale, triggering SDLT and Capital Gains Tax. Incorporation Relief can defer the CGT in narrow circumstances where the properties constitute a genuine business, but this needs specialist advice, not assumption.
Do I need a mortgage broker to get an SPV BTL mortgage?
It's strongly advisable. Limited company BTL lending is a specialist niche — not every lender offers it, rates and criteria vary significantly, and a broker experienced specifically with SPV BTL will know which lenders fit your situation.
How much can I save in tax by using an SPV?
It depends entirely on your income tax rate, gearing (how much mortgage debt you carry relative to rental income), and portfolio size. The saving is largest for higher and additional-rate taxpayers with significant mortgage interest costs — model your own numbers rather than relying on generic examples.
Conclusion
Setting up a property SPV itself is now a roughly £103 all-in exercise through a formation agent — more than the £12–£50 figures still quoted in some older guides, following the Companies House fee rise to £100 on 1 February 2026, but still a modest cost relative to what's at stake in the ownership decision. The SIC code you choose matters for mortgage approval later, and the tax case for incorporation is genuinely strong for higher-rate taxpayers buying new property — much weaker, once SDLT and CGT are factored in, for moving property you already own personally into a company.
