Why most Landlords are now Buying Buy-to-Let Through Limited Companies
Something significant shifted in the UK property market between 2022 and 2026. Why 73% of new limited company landlords are still strategically expanding their portfolios, even as mortgage rates climbed and regulations tightened, tells a compelling story. It’s a story about tax efficiency, long-term planning, and smarter structures. If you’re buying buy-to-let property in 2026, understanding this shift could save you tens of thousands of pounds over the lifetime of your portfolio.
The Tax Problem That Changed Everything
Before 2017, most landlords bought property in their personal name. It was simple. Then Section 24 arrived.
Section 24 of the Finance Act 2015 removed the ability for individual landlords to deduct mortgage interest as a business expense. Instead, they now receive a basic-rate tax credit of 20%. For higher-rate taxpayers, that’s a brutal difference.
For example, a landlord earning £50,000 from employment and £25,000 in rental income could find themselves pushed into the 40% or even 45% tax bracket. So the mortgage interest relief they once counted on simply disappeared. Many landlords saw their profits cut by 30% to 50% almost overnight.
How Limited Companies Changed the Calculation
A limited company operates under entirely different tax rules. It pays corporation tax, currently set at 25% for profits above £250,000 and 19% for small profits below £50,000. More importantly, mortgage interest remains fully deductible as a business expense.
That single difference is what’s driving the structural shift you see across the UK market today. Consider this: a higher-rate taxpaying landlord with a £200,000 interest-only mortgage at 5% pays £10,000 per year in interest. In a limited company, that full £10,000 reduces taxable profit. Held personally, only a 20% credit applies, worth £2,000 against the tax bill.
On a portfolio of ten properties, the annual tax saving can easily reach £20,000 to £40,000. That’s not theory. That’s money sitting in the company rather than paid to HMRC.
Retained Profits and Reinvestment Power
One underrated advantage of the limited company structure is profit retention. Profits left inside the company are taxed at corporation tax rates, not income tax rates. So a higher-rate taxpayer can leave rental profits in the company and reinvest them into the next property.
In contrast, drawing those profits as a dividend triggers additional personal tax. But that choice belongs to the investor. It’s flexibility you simply don’t have as a sole trader landlord.
This is why experienced investors are using their companies as internal funding vehicles. Instead of saving personally and funding deposits from taxed income, they grow the company pot and deploy it efficiently.
What the Data Actually Shows in 2026
The shift towards limited company ownership is now well-documented. Hamptons International reported that in 2023, limited companies accounted for 65% of all buy-to-let mortgage applications. By early 2025, that figure had climbed further.
Companies House data confirms a related trend. Over 400,000 property-holding companies now exist in the UK. A significant proportion are SPVs, which stands for Special Purpose Vehicles, set up specifically to hold rental property.
Even so, not everyone benefits equally from the limited company structure. First-time investors with lower overall incomes and smaller portfolios sometimes find the personal route still workable. That said, the trend is unmistakeable and growing.
SPVs: The Preferred Company Structure
Most property investors don’t use a general trading company. Instead, they set up a dedicated SPV with the SIC code 68100 or 68209. These codes signal to lenders that the company exists solely to hold and manage property.
Lenders including Paragon, Aldermore, and Foundation Home Loans all offer competitive limited company buy-to-let mortgages. Rates are typically 0.1% to 0.5% higher than personal mortgages. But for higher-rate taxpayers, the tax savings far outweigh that premium.
Because SPVs have a clean credit and financial history, lenders can assess them more easily. Many experienced investors run one SPV per property or per project. This separates risk and makes refinancing cleaner.
Five Real Reasons Landlords Are Making the Switch
Here are the five most common reasons landlords and investors are buying through limited companies right now.
- Full mortgage interest deductibility: Companies still deduct 100% of mortgage interest, unlike individual landlords who face the Section 24 restriction.
- Lower corporation tax vs income tax: A basic-rate company tax of 19% to 25% is far less than the 40% or 45% personal income tax many portfolio landlords face.
- Flexible profit extraction: Directors can choose when and how to draw income, mixing salary and dividends for maximum personal tax efficiency.
- Inheritance and succession planning: Shares in a company can transfer more easily than personal property. Investors use this for family wealth planning and pension strategies.
- Portfolio scalability: Lenders assess limited company portfolios differently. Some investors find it easier to grow beyond four properties through a company structure than personally.

The Challenges You Should Know About
The limited company route isn’t without complexity. It’s important to understand the trade-offs before you commit.
Mortgage rates are slightly higher. Most lenders price limited company products at a small premium. For investors with one or two properties and modest incomes, this can outweigh the tax benefit. Always run the numbers with your accountant first.
Transferring existing property is expensive. Moving a personally held property into a company triggers Capital Gains Tax and Stamp Duty Land Tax. So most advisers recommend the company structure for new purchases only, not transfers. However, there are some reliefs available in partnership structures worth exploring.
Admin and Compliance Costs
Running a limited company means annual accounts, corporation tax returns, and Companies House filings. Expect to pay £800 to £2,000 per year in accountancy fees for a property company. That’s a real cost to factor into your projections.
Still, for a portfolio generating £30,000 or more in net profit, the tax savings dwarf the admin costs. Most investors recover their accountancy fees within weeks of the first tax saving.
Mortgage Availability and Personal Guarantees
Some high-street lenders still don’t offer limited company buy-to-let products. But specialist lenders have filled that gap effectively. Most limited company mortgages also require a personal guarantee from the director. So the liability doesn’t disappear entirely. It simply changes form.
How FXM Properties Helps Investors Structure Smarter
FXM Properties works with both first-time investors and experienced portfolio builders across the UK. Our bespoke property sourcing service finds below market value and off-market deals that work inside a limited company structure from day one.
We also manage HMO conversions and project management, which are particularly well-suited to the limited company model. HMOs generate higher yields. Combined with corporation tax efficiency, they can produce exceptional returns compared to standard buy-to-let.
For investors who need to sell quickly, our guaranteed sale solution offers 60-day completion with no sale no fee. This is especially useful when restructuring a portfolio or releasing equity to fund new company purchases.
We understand that every investor’s tax position is different. That’s why our advisory service starts with your goals, not generic advice. We connect you with the right deals, the right legal and tax professionals, and the right strategy for your situation.
Is a Limited Company Right for You?
The honest answer is: it depends on your tax position, your plans, and your timeframe. Here’s a simple rule of thumb.
- If you’re a basic-rate taxpayer with one or two properties, the personal route may still work for now.
- If you’re a higher-rate taxpayer or plan to grow beyond three properties, the limited company structure almost always wins on tax.
- If you’re building a long-term portfolio to pass on to children or use as a pension vehicle, the company structure offers real planning advantages.
- If you’re buying HMOs or multi-unit blocks, the higher yields make the tax saving even more impactful.
Always take advice from a qualified accountant who specialises in property. Don’t rely on one-size-fits-all guidance. The structure you choose at the start affects your options for years ahead.

Frequently Asked Questions
Can I transfer my existing buy-to-let properties into a limited company?
Yes, but it’s rarely straightforward or cheap. Transferring a personally held property into a company triggers Capital Gains Tax on any gain since purchase, plus Stamp Duty Land Tax at standard rates. Most investors leave existing properties in personal names and use a limited company for all future purchases. Some partnership-based strategies allow a more tax-efficient transfer, but these require specialist legal and tax advice.
Do lenders treat limited company buy-to-let applications differently?
Yes. Most specialist lenders now have dedicated limited company mortgage products. They assess the application based on the company’s rental income and the director’s personal guarantee. Rates are usually slightly higher than personal mortgages, typically by 0.1% to 0.5%. However, the lender market has grown significantly. You’ll find competitive options from Paragon, Aldermore, Foundation, and many others.
What is an SPV and why do property investors use one?
An SPV, or Special Purpose Vehicle, is a limited company set up solely to hold property. Investors use SPVs because they have a clean financial history, lenders recognise them easily, and they keep property assets separate from other business activities. Most property SPVs register with SIC codes 68100 or 68209. Many investors run one SPV per property or per project to separate risk and simplify remortgaging.
Is a limited company still worth it if mortgage rates stay high?
For most higher-rate taxpayers, yes. Even at higher mortgage rates, the full deductibility of interest inside a company still produces a better after-tax return than holding property personally under Section 24 rules. The key is to model your specific numbers. A good property accountant can run a direct comparison for your income level, mortgage size, and expected rental yield. FXM Properties can connect you with the right professionals as part of our investor advisory service.
