Trading Company Buy-to-Let Mortgages

Not every limited company is treated the same way by buy-to-let lenders.

SPV (Special Purpose Vehicle): set up and operated in a way that is consistent with property investment/letting activity. The company's income is expected to come mainly from the property and the rent it generates.
Trading company: if the limited company also receives income from other business activities (for example, a wider trade or services unrelated to property letting), it may be viewed as a trading company.

In practice, lenders can be more cautious where there are additional income streams and business activities, because the mortgage decision is still fundamentally tied to the property and the rental income supporting the loan. Where unrelated trading activity is present, it can be harder to separate the buy-to-let risk from other business risks.

Other company structures may exist, but availability and underwriting approach can vary.

Why lenders prefer SPV structures

Specialist buy-to-let lenders that work with limited companies may look for structures that are easy to understand and consistent with the intended investment plan. SPVs are often viewed more favourably because:

Purpose-built structure: the company is set up around property investment rather than broader trading activity.
Clearer underwriting picture: the company's income and expenditure can be easier to map to the property business model.
More consistent documentation: lenders may expect a similar set of information across SPV cases, which can reduce friction during assessment.

It's also worth noting that not every lender offers the same range of products for limited companies, and each lender's criteria can differ. An SPV structure may therefore be relevant when selecting the right lender panel.

How SIC codes can affect lender perception

A common theme in buy-to-let lending is the distinction between:

Property investment (often SPV-style): focused on holding property and receiving rental income.
Trading activity: focused on buying and selling, development, or other commercial trading models.

While lenders will look at the full picture, the SIC code is one of the signals they use to understand which category the company appears to fall into. Choosing SIC code(s) that reflect a letting and holding model can be more consistent for landlords operating an SPV.

A common SIC code mistake to avoid:

Using a code that reflects resale/trading when the strategy is long-term rental income.

Deposits: using a trading company to fund an SPV purchase

SPV mortgages normally require a deposit, and lenders will expect clear evidence of where funds are coming from. Common sources include funds moved from an existing company structure (for example, where a holding or trading company is involved).

The Mortgage Works (TMW) will now allow "Intercompany Loans" as a deposit. TMW will now allow a Trading Company you own to 'loan' your Property SPV Company money for use in the deposit. An essential bit of criteria as TMW (& most lenders) don't offer BTL mortgages for trading companies.

With TMW, both companies are required to have the same directors and shareholders, and the donor company must have been actively trading for a minimum of 12 months.

Put simply, this allows your trading business (Car Sales, Widget Maker, Manufacturer, IT Consultant, etc.) to loan funds to a Property SPV. It's an excellent way to diversify your income and investments.

TMW is late to this, following in the footsteps of Aldermore, CHL, Fleet, Foundation, Kensington, KRBS, Landbay, and many others.

You should talk to your accountant about this arrangement.

What lenders say about trading companies

Layered and other complex company structures

A few landlords now hold property through more complex company setups. Some sit within layered structures for tax, ownership, or long-term planning reasons.

Those cases can quickly narrow down lender choices.

Your tax advisers may prefer complicated ownership structures such as parent companies, which most mortgage lenders still do not allow and should be avoided.
