Commercial investment mortgages for let business property
A commercial investment mortgage is long-term borrowing secured on a building let to business tenants and repaid from the rent…
How the main ownership structures for business premises work, from trading company and SPV to partnership, SSAS and SIPP, and how lenders approach each.
This guide is for company directors, practice partners and business owners who are about to buy premises and are being asked a question that comes before the mortgage: who should own the building? It explains how each common structure works and how lenders approach it. It does not give pension, tax or legal advice, and the right answer depends on your circumstances, so the choice should be made with a regulated pension adviser, your accountant and a solicitor. Smart Funding Solutions is a broker that arranges the borrowing once the structure is settled, through lenders on our panel of 300+, for facilities from around £10,000 to £500,000+, with larger facilities available in suitable cases. Our commercial property finance hub covers the funding routes themselves.
| Owner | Who borrows | Where the rent goes | Points to raise with advisers |
|---|---|---|---|
| Trading company | The company | No rent; the company occupies its own building | The property is exposed to trading risk and is included if the company is sold |
| Separate property company (SPV) | The SPV, usually with guarantees | From the trading company to the SPV | Corporation tax in the SPV; how profits reach shareholders; how the deposit is funded |
| Individuals, partners or an LLP | The owners personally or the LLP | From the business to the owners | Personal liability; income tax on rent; what happens when a partner leaves |
| SSAS or SIPP | The scheme trustees, within strict limits | From the business into the pension | Borrowing limit, market rent, liquidity, connected-party rules and inheritance tax |
Lenders are comfortable with each of these when the structure is set out clearly. What changes is who signs, what the lender checks and how long the process takes.
The simplest route. The company buys the building, the lender underwrites the company's trading as it would for any commercial mortgage, and there is one set of accounts and one borrower. The drawbacks show later. The building sits on the same balance sheet as the trading risk, so if the business fails, creditors can look to it. And if the owners later sell the business but want to keep the property, extracting it from the company can involve tax and costs that would have been avoided by holding it separately from the start.
A special purpose vehicle, or SPV, is a limited company set up only to own the property. It is usually owned by the same shareholders as the trading company, or sits alongside it under a holding company. The SPV buys the building and grants the trading company a formal lease at a market rent.
How lenders view it. The SPV has no trading history, so the lender looks through it to the business paying the rent. It will want the lease, the trading company's accounts and, in most cases, personal guarantees from the directors and a guarantee from the trading company. In effect it underwrites the trading business, but takes security over a property held in a separate entity.
Why owners choose it. The property is separated from day-to-day trading risk, and the business and the building can be sold independently: a buyer of the business can become a tenant, while the owners keep the property as an investment. The rent paid by the trading company is generally a business expense.
What it costs. Two sets of accounts, a lease that must be on commercial terms, corporation tax on the SPV's rental profit, and a further tax step whenever profits are taken out by shareholders. How the deposit reaches the SPV, whether by shareholder loan, a loan from the trading company or new share capital, has its own tax consequences. Stamp Duty Land Tax is payable on the purchase in the usual way.
Professional firms often hold premises outside the practice itself. In a GP, dental, veterinary or law partnership, the building may be owned by some partners and not others, or by a separate property LLP whose members overlap with the practice. That lets property ownership be bought and sold separately from a share of the practice, which matters when partners retire or new partners join. The practice pays rent to the property owners.
Lenders read both the partnership agreement and any property-owning agreement, because they need to know what happens if a property-owning partner leaves, dies or wants to sell. A clear mechanism for buying out a departing partner's share is often a condition of lending. For NHS general practice in England, the rent or borrowing costs on surgery premises may be reimbursed under the NHS premises costs directions, and lenders that know the sector take that into account. Sector detail is on our pages for GP surgery premises, dental practice premises and solicitor office purchase.
A small self-administered scheme (SSAS) is an occupational pension scheme set up by a company, usually for its directors and key staff, who are often its trustees. A self-invested personal pension (SIPP) is a personal pension run by a provider that allows a wider range of investments. Both can buy commercial property, and owner-managed businesses often use them to buy the premises the business trades from. The rules below are set out in HMRC's guidance on tax on investments for pension trustees.
A registered pension scheme can borrow up to 50% of the net value of its assets, measured immediately before the loan. Borrowing above that limit triggers tax charges. Pension schemes generally cannot hold residential property without tax charges, so the building must be genuinely commercial.
Illustration only, with round hypothetical figures. A SSAS with £300,000 of net assets could borrow up to £150,000, giving it up to £450,000 to spend before costs. If the target building costs £420,000 plus SDLT, legal and valuation fees, the scheme can probably fund it without any further contribution, although it would then hold most of its value in one property.
Fewer lenders will lend to pension schemes than to companies, and the process has more parties. Expect them to look at:
Timetables are longer than for a company purchase, so build in time for the administrator, the independent valuation and the lease to be agreed.
Pension advice is regulated, and MoneyHelper explains how to choose a financial adviser. Your accountant should model the tax position of each route before anything is signed.
Once your advisers have settled the structure, we approach lenders on our panel that lend to it, whether a trading company, an SPV, a partnership or LLP, or pension trustees, and compare terms with you. The lender makes the decision. For the wider steps of a purchase, see buying business premises, and if you already own the building and want to change its loan, commercial property refinance. It is free to enquire; any broker fee is disclosed separately before you proceed.
This guide is general information, not financial advice. Lenders set their own criteria, rates and terms, and all finance is subject to status.

No. Rent between a pension scheme and a connected business must be at a market rate, normally supported by an independent valuation, and rent reviews should follow the lease. Undercharging can be treated as an unauthorised payment with tax charges. If cash flow is the concern, discuss it with your pension adviser and scheme administrator before agreeing the lease.
A pension can buy a building from a member or their company at market value, using an independent valuation. The sale may have stamp duty, capital gains and VAT consequences for both sides, so the tax position must be checked first. Some schemes also accept property as a contribution in specie, which has its own rules.
Usually yes. Because an SPV has no trading history of its own, lenders typically ask for guarantees from the directors and often from the trading company paying the rent. Our guide to personal guarantees explains what signing one involves.
Yes. An LLP can borrow in its own name, and lenders will usually want to see the members' agreement and may ask members for guarantees. Our guide to limited companies and LLPs covers the structural differences.
Yes, a pension scheme such as a SSAS can buy commercial property jointly, owning a share alongside the company or other owners. Each owner's share, the lease and any borrowing must be set out clearly, and the scheme still has to charge a market rent and stay within its own borrowing limit. Lenders will want to understand the full structure before offering finance. Take regulated pension and tax advice first, then see commercial mortgages for the funding side.
