An SPV (special purpose vehicle) is a limited company that exists solely to hold property, while a trading company is a limited company that runs an active business, selling goods or services, and the distinction decides which mortgages a company can get, how lenders price them, and how cleanly the structure runs. The two are identical at Companies House, a private limited company is a private limited company, but to a buy-to-let lender they are different species, and confusing them is one of the most expensive structural mistakes a property investor can make.
We sit on the mortgage side of this distinction every day: the case that arrives as "my company will buy it" and needs unpicking into which company, holding what, funded how. This guide sets out the difference, why lenders care so much, and how to structure when you have both a business and property ambitions.
The difference is purpose, evidenced by activity and by SIC code.
A special purpose vehicle is incorporated for one narrow job: buying, holding and letting property. Its SIC code at Companies House is property-specific, 68100 (buying and selling own real estate) or 68209 (letting of own or leased real estate), with 68320 (property management) acceptable to some lenders alongside them. It has no employees beyond the directors, no customers in the trading sense, no stock, no premises. Its entire balance sheet is property, mortgage debt and director's loans; its entire profit and loss is rent in, costs and interest out.
A trading company earns its living from activity: a consultancy, a builder, an agency, a software firm, a shop. Its SIC codes describe that trade, its accounts carry debtors, creditors, work in progress, payroll. It may be far more valuable than any SPV, and far more creditworthy in conventional terms. It is still, to a buy-to-let lender, the harder borrower, because its risks are business risks, and the lender cannot underwrite them from a rental schedule.
A glance at the two companies' filings makes the contrast concrete. The SPV's micro-entity accounts run to a few lines: one fixed asset (the property at cost), one creditor (the mortgage), one director's loan, rent in, interest and costs out. The trading company's accounts carry turnover, cost of sales, staff costs, debtors and work in progress, numbers an underwriter can only assess by understanding the business behind them. The first set can be underwritten in minutes against a rental schedule; the second cannot, and that asymmetry is the entire story of how the two are treated.
The test is substance, not label. A company registered under 68209 that also invoices for consultancy is a trading company in any underwriter's eyes. A dormant trading company cleaned out and repointed at property can be accepted as an SPV by some lenders and refused by others; a fresh incorporation is usually simpler than rehabilitating an old vehicle.
Because the credit assessment is clean. When an SPV applies for a limited company buy-to-let mortgage, the lender underwrites three things: the property, the rent against the interest coverage ratio, and the directors who guarantee the debt. There is nothing else in the company to assess. That simplicity is worth real money: the whole specialist panel, Paragon, Fleet Mortgages, Kent Reliance, Foundation Home Loans, Landbay, Precise and the rest, lends to SPVs on standard terms, new SPVs with no trading history included, since the vehicle's age tells the lender nothing the directors' covenants do not.
A trading company borrower forces the lender to underwrite the business as well as the property:
The market's response is structural: most buy-to-let lenders simply decline trading companies, and the minority that accept them, certain commercial arms and specialist lenders, price the extra underwriting at commercial-mortgage levels rather than buy-to-let levels. Trading activity inside the borrowing vehicle is one of the recurring causes in our guide to why limited company mortgage applications get declined.
Yes, but from a narrow shelf at a wider price. A handful of lenders will mortgage a rental property inside a trading company where the trade is established, profitable and clearly separable from the property, typically requiring two or more years of accounts, full trading underwriting, and pricing 0.5% to 1% above the equivalent SPV product, sometimes structured as a semi-commercial facility. It can make sense for a company buying its own premises (a genuinely commercial transaction, outside this site's scope) or where a single legacy rental already sits in the trade and refinancing in place is cheaper than restructuring.
For a deliberate buy-to-let purchase, though, borrowing through the trading company is almost never the right answer, because the alternative is so cheap and so standard: incorporate an SPV alongside the trade and let the SPV borrow. Which raises the real question most business owners are actually asking.
The scenario behind most of these enquiries: a profitable trading company has surplus cash, and the owner wants that cash working in property. Three structures exist, and only two are sensible.
Structure 1: the trading company buys the property directly. Cheapest on paper (no new company, no funds movement), and almost always wrong. The lender pool collapses, the pricing rises, the property is exposed to trading creditors, and a future sale of the trade is contaminated by a rental asset the buyer does not want. We rarely place cases this way by choice.
Structure 2: a sister SPV funded by intercompany loan. The owner incorporates an SPV; the trading company lends it the deposit under a documented intercompany loan agreement; the SPV takes the SPV mortgage and holds the property. The trade and the property are ring-fenced from one another, the full lender panel is in play, and the cash moved without a personal tax event. Lenders accept intercompany deposits with a clean paper trail: a written agreement, evidence the cash was unencumbered, and clarity that repayment will not undermine the mortgage. Subordination to the mortgage lender is commonly required.
Structure 3: a holding company group. A holding company owns both the trading company and the property SPV. Cash moves from trade to holdco as a dividend (typically tax-free between group companies) and down into the SPV as equity or loan. Cleaner than sister-company lending at scale, friendlier for reinvestment and eventual sale of either side, and increasingly the default for owners building serious portfolios alongside a business. The price is more administration and more entities to file for; the group also needs explaining to lenders, some of whom cap structures at two or three layers.
A worked illustration of Structure 2, since it is the one most owners land on. A consultancy with £80,000 of surplus cash incorporates a sister SPV under SIC code 68209. The consultancy lends the SPV £70,000 under a written, interest-free intercompany agreement, subordinated to the mortgage lender. The SPV buys a £220,000 rental with a £165,000 limited company mortgage, the £70,000 covering deposit, stamp duty and costs. No dividend was paid, so no personal tax arose on the funding leg; the consultancy holds a receivable it can call back as the SPV's profits allow; and if the consultancy ever hits trouble, its creditors reach the receivable, not the property itself. The structure costs one incorporation, one loan agreement and a second set of annual accounts.
Which of 2 and 3 fits depends on scale, exit plans and tax positions across the group, a genuine three-way conversation between you, your accountant and us, ideally before the SPV is incorporated rather than after an offer is accepted. Setting the vehicle up correctly takes a day; the steps are in our guide to setting up an SPV for buy-to-let.
Less than people expect on the headline, and more in the texture. Both structures pay corporation tax at the same 19% small profits rate and 25% main rate with marginal relief between; both deduct mortgage interest in full, untouched by Section 24; both pay tax on chargeable gains at corporation tax rates when property is sold. The differences that matter:
Since the deposit route is where these structures meet the mortgage application, the mechanics deserve their own section. Whichever structure carries the cash, the lender will trace it, and the standard of evidence is documents, not explanations:
Underwriters do not object to intercompany money; they object to undocumented intercompany money. A transfer that appears in the SPV's account three weeks before application with no agreement behind it will generate queries, delays and sometimes a decline, where the same funds with a one-page agreement and a clean trail are a non-event.
A short field guide from our broker desk, in descending order of cost:
The pattern across all five: the SPV's value is its emptiness. Everything you add to the vehicle beyond property, debt and director loans subtracts from its usefulness.
If you are buying rental property and you do not run a business: one clean SPV, property SIC code, director's loan deposit. If you run a trading company and want its cash in property: a separate SPV funded by intercompany loan, or a holding group if you are building at scale, and never the trade itself buying the rental. If you already hold property personally and are weighing a move into a company, that is a different transaction with capital gains tax and stamp duty legs, covered in our transfer property to a limited company service page.
