If you are a landlord or property investor in 2025, the question of whether to hold property in an SPV or a trading company is more relevant than ever. With tax rules continuing to evolve, lender appetite shifting, and portfolio structuring becoming increasingly strategic, the decision you make today can materially influence your long-term returns. The right structure can secure more favourable mortgage terms, reduce administrative friction, and create clearer pathways for expansion. The wrong one can restrict lender choice, increase tax exposure, and cause issues years down the line.

This topic sits at the centre of modern property planning. Investors are no longer simply buying properties; they are building businesses, planning generational wealth strategies, and aligning their structures with long-term exit goals. Selecting the appropriate ownership route has become as important as choosing the property itself. In the context of higher rates, tighter underwriting, and more professionalised landlord markets, structure is now one of the biggest differentiators in a successful portfolio.

At Willow Private Finance, we regularly support clients who are transitioning from personal ownership or trading-company ownership into SPVs, particularly as they expand their portfolios, plan their tax strategy, or prepare for refinancing. This guide brings together lender expectations, tax considerations, and real-world insight to help you make an informed choice. For related reading, many clients also find it useful to review our article on Limited Company Mortgages Explained and our strategic guidance on UK Buy-to-Let Strategies in 2025.

Understanding What an SPV Is in 2025

A Special Purpose Vehicle (SPV) is a limited company created specifically to hold property. It has one purpose: to acquire, manage, or develop real estate. There is no unrelated trading activity, no sales of goods or services, and no external income streams. This simplicity makes the company’s finances predictable, transparent, and easy for lenders to assess. Most mortgage lenders now prefer SPVs over standard trading companies for buy-to-let and portfolio finance.

The predictability of an SPV means that lenders can understand its financial position without filtering through unrelated business activity. Accounts are typically clean, with income generated solely from rental receipts or development proceeds. As a result, lenders face fewer variables when assessing affordability, gearing, or operational risk. In 2025, with lenders taking a firmer approach to risk management, this clarity is extremely valuable.

SPVs also allow investors to ring-fence their property activity. This ensures that liabilities arising from other ventures do not impact property holdings. For landlords seeking scalability, this is a considerable advantage. Many lenders offering portfolio finance or complex refinancing will only consider applications from SPVs, especially when the investor plans to acquire multiple properties over a short timeframe.

What a Trading Company Represents

A trading company is a limited company engaged in commercial activity. It may sell products, offer professional services, employ staff, make VAT submissions, and operate in broader markets unrelated to property. Its accounts reflect this activity, often showing payroll, business expenses, sales, and revenue streams outside the property sphere.

When property is held inside a trading company, lenders must assess the wider business risk. This includes the company’s financial health, operational stability, and sector exposure. Even profitable trading companies create additional underwriting complexity because the lender must ensure that property-backed borrowing is not exposed to risks associated with the trading activity. As a result, many buy-to-let lenders avoid trading companies entirely and prefer SPVs, especially for investors aiming to grow their portfolios.

There are circumstances where a trading company may be considered appropriate for holding property, but these are usually edge cases. For example, a construction firm that builds and sells homes might logically hold development stock inside the main company. However, outside of such scenarios, most investors benefit from keeping their property activity ring-fenced within an SPV.

How the Choice Affects Mortgage Access in 2025

Mortgage lenders have strengthened their risk controls significantly in recent years. In 2025, underwriting teams place particular emphasis on transparency, separation of business risk, and the clarity of financial accounts. SPVs offer all three. Because they exist solely for property, they remove many variables that lenders view as potential risk indicators.

Lenders prefer SPVs because assessing affordability, leverage, and overall exposure becomes far more straightforward. Rental income is clearly identifiable. Operating costs relate solely to the property business. Future income projections are not complicated by unrelated commercial activities. This reduces the time spent on compliance checks, credit assessment, and internal sign-off.

By contrast, trading companies make underwriting more complicated. Before approving finance, the lender must understand the stability of the trading business, how much of its revenue is recurring, whether it carries any significant liabilities, and how much risk the company introduces to property-backed borrowing. These additional reviews can slow down or even halt the mortgage process.

Investors planning to scale will almost always find that an SPV provides smoother access to high-quality lenders, better refinance pathways, and, in many cases, more competitive pricing.

Tax Considerations When Comparing SPVs and Trading Companies

While both SPVs and trading companies pay Corporation Tax, the tax treatment of property activity differs in several key respects. Mortgage interest relief, for example, is fully available within SPVs. This is not the case when holding property personally, and it can significantly affect net profitability.

SPVs allow clearer separation between property income and other business revenue. This simplifies tax reporting, supports long-term planning, and often improves exit value for future buyers who prefer clean, ring-fenced structures. A well-organised SPV structure is easier for accountants to work with and helps families integrate their property portfolio into broader inheritance planning strategies.

Trading companies, by contrast, often have payroll costs, VAT obligations, and mixed-purpose transactions. These can complicate tax planning, reduce flexibility, and make it harder to present a coherent financial position during refinancing. While there may be reasons to funnel trading profits into property purchases, investors must consider how this impacts future tax efficiency and lending access.

Investors should also consider long-term goals. For example, if a family eventually plans to pass the business to children, holding rental properties within a trading company can mix operating business risk with long-term investment assets. For many families, separating these streams through SPVs creates clearer governance and a more secure succession plan.

Asset Protection, Liability Management, and Risk Control

An SPV offers structural protection. It shields property assets from claims, debts, or liabilities arising in other parts of your business life. If you operate a trading company, any financial issues within that business could potentially affect the property portfolio if the assets are held within the same entity.

In a period of economic unpredictability, with insolvency figures rising across multiple sectors, many investors appreciate the security that ring-fenced ownership brings. If a trading company faces financial difficulty or legal challenges, assets owned by an SPV remain protected.

Trading companies, however, combine business risk with property ownership. While this may be manageable for experienced operators in specific industries, it is generally unsuitable for long-term investment portfolios, which require stability, predictability, and strategic clarity.

When a Trading Company May Still Be Appropriate

Although SPVs dominate the 2025 lending and tax landscape, there are circumstances where using a trading company can be justified. For example, if your main business involves property development, construction, or a related field, holding certain property assets within the trading company may streamline operations. Alternatively, if you intend to use accumulated trading profits to buy property quickly—without extracting funds personally or setting up a new entity—the trading company may serve as a temporary vehicle.

However, these situations tend to be exceptions rather than the rule. Even in these cases, investors should seek advice to ensure that the structure aligns with both tax objectives and lender requirements. Most buy-to-let landlords and long-term investors benefit from separating their trading and property activity entirely.

The Mistakes Investors Commonly Make

One of the most frequent errors we see at Willow Private Finance is mixing trading income and property activity within a single company. While this may appear convenient at first, it often leads to complex accounts, limited lender choice, and future refinancing challenges. Investors may also use incorrect SIC codes, which immediately signals a red flag to underwriters. Another common misconception is assuming accountants will resolve issues created by structural choices. In reality, structure is both a tax decision and a lending decision, and the two must align from the outset.

We also see investors who hold their first property in their personal name and then switch strategy mid-portfolio. Transitioning to an SPV later is certainly possible, but poorly planned restructuring can incur unnecessary costs, reduce tax efficiency, and complicate refinancing. Investors should think several steps ahead rather than simply focusing on the next acquisition.

Frequently Asked Questions

Q1: Is an SPV always the best option for landlords in 2025?
An SPV is usually the most efficient structure for buy-to-let investors, but individual circumstances, trading activity, and long-term planning objectives must be considered before making a decision.

Q2: Do lenders still accept trading companies for property purchases?
Some may, but underwriting is more complex and fewer lenders are willing to do so. Most landlords will secure better access to competitive lending by using SPVs.

Q3: Are SPVs more tax efficient than trading companies?
They can be. SPVs offer clearer separation between rental income and trading activity, simplify Corporation Tax planning, and preserve mortgage interest relief.

Q4: Will using an SPV limit personal liability?
An SPV can ring-fence liabilities, but directors may still need to provide personal guarantees. The structure does, however, provide strategic protection against trading-related risks.

Q5: Can I move properties from a trading company into an SPV?
Yes, but it must be planned carefully to avoid tax charges, lender issues, or unnecessary costs. Professional advice is essential.



Q6: Does an SPV make refinancing easier?
In most cases, yes. SPVs align with lender expectations and simplify underwriting, leading to smoother refinancing pathways.
