In 2025, an increasing number of landlords and property investors are purchasing and refinancing their portfolios through limited company structures. This shift has been building over the past few years, but it is now becoming mainstream — particularly among higher-rate taxpayers, professional landlords, and those planning to scale beyond a handful of properties.

The motivations behind this trend are clear. Limited company mortgages, often arranged through special purpose vehicle (SPV) structures, offer improved tax efficiency, clearer separation of liabilities, and growing support from lenders who now view SPVs as a standard part of the professional landlord landscape. For many investors, the structure offers a smarter, more strategic way to manage property portfolios in an evolving tax environment.

Why Landlords Are Choosing Limited Company Mortgages

The appeal of using a limited company lies in both financial and structural advantages. When held within an SPV, rental properties can be managed more efficiently, profits can be reinvested with fewer restrictions, and long-term planning — including inheritance and succession — becomes far easier to navigate.

One of the most significant advantages lies in tax efficiency. Rental profits within a limited company are taxed at the corporation tax rate (currently 25%), which is often far lower than the income tax rates that apply to individuals, especially higher and additional-rate taxpayers. For investors earning in the 40–45 per cent bracket, this can represent a substantial saving over time.

Equally important is the ability to deduct 100 per cent of mortgage interest from rental income before calculating tax. This stands in sharp contrast to personal ownership, where Section 24 restrictions limit mortgage interest relief. For leveraged landlords, this difference alone can make a limited company structure significantly more profitable.

Another practical benefit is portfolio growth and scalability. An SPV creates a cleaner legal and financial separation between personal and business activities, making it easier for lenders to assess borrowing and for investors to ring-fence liability. This simplicity becomes increasingly valuable as a portfolio expands — allowing multiple properties to be managed, refinanced, or sold under one company umbrella.

Finally, limited company ownership often supports better long-term estate and legacy planning. Instead of transferring entire properties, investors can gift or sell shares in the company to family members, simplifying inheritance arrangements and potentially reducing future tax exposure.

What Lenders Are Looking for in 2025

As more lenders compete in the limited company buy-to-let space, the range of products available has expanded considerably. However, lenders apply specific criteria to ensure that applicants meet structural and financial standards suitable for corporate borrowing.

In most cases, the borrower must use a Special Purpose Vehicle (SPV) — a limited company set up specifically to hold property investments. The SPV should have relevant SIC codes aligned to property letting or management activities, such as 68209, and should not engage in any unrelated trading. Many lenders will decline applications from trading companies or SPVs with non-property-related activities.

Directors and shareholders are generally required to provide personal guarantees, as lenders want the reassurance of individual accountability behind the company structure. Minimum deposits typically range from 20 to 25 per cent, and while landlord experience is preferred, an increasing number of lenders are now willing to consider first-time investors if the overall profile is strong.

Interest rates on limited company products tend to be slightly higher than those available for personally owned buy-to-lets. However, this difference is often outweighed by the tax efficiency gained through the company structure. Standard loan-to-value (LTV) ratios reach up to 80 per cent for typical single-let properties and 70 to 75 per cent for more complex assets such as HMOs or multi-unit blocks.

Mortgage terms are broadly similar to those for individual buy-to-lets, with two-, five-, and ten-year fixed rate products available. Lenders apply rental stress testing at higher assumed interest rates — typically 125 to 145 per cent at 5.5 to 6 per cent — to ensure the rental income comfortably covers repayments under potential rate rises.

Limited Company vs. Personal Name Ownership

The difference between holding property personally and through a limited company structure has never been clearer. While the traditional approach still works for smaller landlords or those in lower tax brackets, the limited company model provides structural advantages that compound over time.

In a limited company, rental profits are taxed at 25 per cent, while personal ownership exposes income to rates between 20 and 45 per cent. Companies can also deduct all mortgage interest before tax, whereas individual landlords can no longer do so fully under current legislation.

From a legal perspective, limited company ownership means that the property is held by the company, not the individual. This distinction provides separation of liability and can simplify financial reporting. For inheritance planning, transferring company shares is often far more straightforward than transferring individual property titles, allowing for smoother succession and potentially lower associated costs.

Mortgage availability continues to broaden. While there are still fewer products for limited companies than for personal names, the gap is narrowing rapidly. Lenders increasingly recognise SPVs as standard vehicles for professional landlords, especially those managing larger portfolios.

The main trade-off is administrative. A company must file annual accounts, maintain bookkeeping, and meet statutory obligations. These tasks introduce accounting costs and compliance work, but many investors find the benefits outweigh the additional complexity.

Is a Limited Company Mortgage Right for You?

A limited company structure is not automatically the right choice for every investor. For those with one or two small properties or those within the basic rate tax band, personal ownership may still be simpler and more cost-effective.

However, for higher-rate taxpayers, professional landlords, or investors planning to build a multi-property portfolio, the advantages of using a limited company can be considerable.

Before proceeding, it is vital to weigh the total cost of ownership — including accounting fees, administrative requirements, and slightly higher mortgage rates — against the potential tax savings and long-term benefits. A specialist mortgage broker can help model both options side by side, taking into account your personal income, borrowing plans, and exit strategy to determine the most efficient structure.

Avoid Using a Trading Company for Property Purchases

One of the most common and costly mistakes investors make is attempting to buy investment property through an existing trading business. Lenders are highly restrictive about this and typically insist that property be held within a clean SPV.

A company engaged in other commercial activities — even if property investment is only a secondary interest — will generally be declined. Using a dedicated SPV not only ensures compliance with lender requirements but also keeps financial reporting clear and ring-fenced.

Market Trends and Outlook for 2025

The limited company mortgage market has matured rapidly. More lenders are now actively competing for SPV business, driving innovation in product design and pricing. Stress testing has become more flexible, and underwriting standards have adapted to reflect the professionalisation of the landlord market.

Portfolio landlords, in particular, are increasingly refinancing personally owned properties into limited companies. This trend is often driven by the desire to free up personal income capacity, simplify lending structures, and create a more tax-efficient framework for long-term growth.

Looking ahead, this segment of the market is expected to continue expanding. As tax rules and regulatory requirements evolve, corporate ownership will likely remain the preferred structure for serious investors who want to build scalable, resilient property businesses.

Frequently Asked Questions

Are limited company mortgage rates higher than personal ones?
Typically, yes — by a small margin. However, the difference is often offset by the tax efficiency of the structure, especially for higher-rate taxpayers.

Can I use my trading company to buy investment property?
No. Most lenders will not accept applications from trading companies. You should establish a dedicated SPV with appropriate SIC codes for property letting or management.

Do I need landlord experience to apply?
Not necessarily. Many lenders prefer applicants with experience, but some are open to first-time investors if they demonstrate financial stability and a clear understanding of the market.

What deposit will I need for a limited company mortgage?
Most lenders require between 20 and 25 per cent as a minimum deposit, although higher deposits may unlock better rates and terms.

Can I transfer my existing properties into a limited company?
Yes, but doing so triggers a sale and repurchase in legal terms, which can lead to stamp duty and capital gains implications. It’s crucial to seek specialist tax and legal advice before proceeding.
