Discover why 95% of landlords are now using Limited Companies (SPVs) for buy-to-let. Explore tax benefits and affordability advantages of limited company buy to let.
With limited company buy to let the UK has undergone a tectonic shift, and that’s before we get into the Renters Reform Bill. What was once a niche tax strategy used by only the largest professional landlords has become the default setting for the modern investor.
At Lime Finance Solutions, we have witnessed this evolution firsthand. The “Limited Company Buy to Let“—often referred to as an SPV (Special Purpose Vehicle) structure—is no longer just an alternative; it is the default vehicle for the UK rental market.
“Limited company is by far the most common structure we see with buy to let lending. Today, over 95% of all our buy to let lending is to limited companies. An SPV structure is no longer niche; it is the norm. Don’t let anyone tell you otherwise.” — David Farmer, Lime Finance Solutions.
The surge in limited company buy to let incorporations for property – with over 60,000 new companies set up in 2024 alone – is driven by three primary factors:
Since the phased introduction of Section 24, individual landlords can no longer deduct mortgage interest from their rental income before paying tax. Instead, they receive a 20% tax credit.
For higher-rate taxpayers, this often means being taxed on “profits” that don’t actually exist after the mortgage is paid. In contrast, a Limited Company treats mortgage interest as a 100% deductible business expense. You only pay Corporation Tax on the actual profit remaining.
To put this into something tangible, this comparison show the difference on a single buy to let property with £20,000 gross rental, comparing between an SPV limited company and a 40% tax payer owning in personal name:
| Feature | Personal Ownership (Higher Rate) | Limited Company (SPV) |
| Gross Rental Income | £20,000 | £20,000 |
| Allowable Expenses | £2,000 | £2,000 |
| Mortgage Interest | Not Deductible (20% credit) | £10,000 (Fully Deductible) |
| Taxable Profit | £18,000 | £8,000 |
| Tax Rate Applied | 40% (Income Tax) | 19% (Corporation Tax*) |
| Initial Tax Bill | £7,200 | £1,520 |
| Mortgage Tax Credit | -£2,000 (20% of £10k) | N/A |
| Total Tax Paid | £5,200 | £1,520 |
| Net Cash After Tax | £2,800 | £6,480 |
The bottom line shows the difference and starts to explain the growth of limited company buy to let lending. Remember that this is correct at time of publication – check with your accountant before doing anything because there can be other ways to acquire property.
Corporation Tax (currently 19%–25%) is significantly lower than the 40% or 45% personal income tax brackets. If your goal is to grow a portfolio, you can retain profits within the company to fund your next deposit without them being eroded by personal tax.
Passing property to the next generation in a personal name can trigger massive Capital Gains Tax (CGT) and Stamp Duty liabilities. With a company, you can gradually transfer shares to family members, providing a far more flexible and tax-efficient route for inheritance.
You might wonder why banks, who historically preferred “bricks and mortar” individuals, are now falling over themselves to lend to SPVs for limited company buy to let.
The reason is underwriting stability. Lenders view a Limited Company buy to let as a professional business entity. Because the limited company buy to let is insulated from the director’s personal “lifestyle” expenses (like school fees or personal credit card debt), the rental income is seen as more “secure” within the corporate bubble.
Remember also that the main banks are like oil tankers, they take time to turn. Something new? The habbit is to wait it out and see what happens. If the main banks piloted the Evergiven the Suez would still be blocked, as an unnamed journalist told me recently…
Furthermore, the sheer volume of demand has forced competition. There are now more fixed-rate products available for limited companies than ever before, and the historical “premium” on interest rates for companies has narrowed significantly.
One of the most practical reasons to choose the limited company buy to let route is the affordability calculation. This is often the number one reason our clients go the limited company route, it is an answer to the necessity of borrowing.
Lenders use an Interest Cover Ratio (ICR) to determine how much they will lend you. Because of the tax advantages mentioned above, lenders apply a lower “stress test” to companies than to individuals:
The difference it makes to borrowing capacity is huge. It can seem strange given the rental is the same and the property is the same, but when you factor in the tax position it does make sense. There is more cash in an SPV, and cash pays the mortgage, compared to a buy to let in personal name.
“The difference in borrowing capacity is staggering. Because the tax treatment is cleaner, lenders allow for higher leverage. This can make a material difference when expanding your portfolio; it’s often the difference between being able to afford that next property or being stuck. It is the number one reason our clients go this route.” — David Farmer, Lime Finance Solutions.
While the benefits are clear, it is not a “one size fits all” solution. If you are a basic-rate taxpayer with a single property, the administrative costs of a company (accounting fees, Companies House filings) might outweigh the tax savings.
However, for those looking to build a legacy and scale a portfolio, the SPV is the undisputed champion.
Watch out for the next budget and always talk it through with your accountant. Personal or limited company, we can help with the buy to let mortgage – fear not.
Investing in property through a Limited Company (often called a Special Purpose Vehicle or SPV) is now the industry standard. However, the transition from personal ownership to a corporate structure can be complex. Here are the answers to the most common questions our clients ask at Lime Finance Solutions.
An SPV is a company set up specifically for a single purpose – in this case, holding and managing residential or commercial property. Lenders prefer SPVs because they are “clean” entities with no trading history in other industries, making the underwriting process straightforward and secure.
Due to Section 24, individual landlords cannot deduct mortgage interest from their rental income before paying tax; they only receive a 20% tax credit. With a Limited Company buy to let, mortgage interest is treated as a 100% deductible business expense. You only pay Corporation Tax (19%–25%) on the remaining profit.
Yes. This is one of the biggest advantages. Because the tax treatment is more efficient, lenders use a lower Interest Cover Ratio (ICR) for limited company buy to let:
Personal Name: Usually requires 145% coverage.
Limited Company: Usually requires only 125% coverage. This lower “stress test” often allows you to secure a larger loan for the same property.
Historically, there was a significant premium for limited company buy to let borrowing. However, as the market has shifted, competition has increased. While rates can still be slightly higher than personal mortgages, the gap has narrowed significantly, and the tax savings often far outweigh the difference in interest.
Yes, but this is treated as a sale and purchase. The company must buy the property from you at market value. This may trigger:
Capital Gains Tax (CGT) for you as an individual.
Stamp Duty (SDLT) for the company.
Legal Fees for the transfer.
Note: Always consult with your accountant to perform a “cost-benefit analysis” before moving existing assets.
Absolutely. Many lenders are happier to provide Limited Company buy to let mortgages to first-time investors, provided the SPV is set up correctly and the personal directors meet the lender’s standard credit and income criteria.
While the tax and borrowing benefits are significant, there are additional responsibilities:
Administrative Costs: You will need to file annual accounts with Companies House and Corporation Tax returns.
Accountancy Fees: These are generally higher for a company than for a personal tax return.
Reduced Privacy: Company directors and accounts are listed on the public register at Companies House.
Funds can be withdrawn via salary, dividends, or director’s loan repayments (if you loaned the company the initial deposit). Each method has different tax implications, so it is vital to coordinate with your tax advisor to find the most efficient strategy.
