For UK business owners, the decision to buy commercial property is rarely just about bricks and mortar. The structure used to hold the property has real consequences for tax, borrowing, and what happens when you eventually sell or pass the business on.
Buying through a limited company has become the default route for many trading businesses and property investors over the past decade, partly because of changes to personal tax relief and partly because the lending market has caught up.
The structure is not automatically right for everyone, though, and the mortgage side of the equation is more layered than residential lending.
Here is what business owners should weigh up before signing anything.
What Should You Know Before Buying a Commercial Property Through Limited Company?
Why Business Owners Hold Commercial Property in a Limited Company?
There are four main reasons:
- Tax on rental profit: Rental income inside a limited company is taxed at the corporation tax rate (currently 25% for profits above £250,000, with marginal relief between £50,000 and £250,000, and 19% below £50,000). Compare that with personal income tax at 40% or 45%, and the gap matters once rental income is meaningful.
- Mortgage interest is fully deductible: Section 24 restrictions that hit personal landlords do not apply to limited companies. Interest is treated as a normal business expense and reduces taxable profit pound for pound.
- Asset protection and ring-fencing: Holding property in a separate company keeps it off the balance sheet of the trading business, which helps with risk management and future sale.
- Succession and ownership flexibility: Shares in a property company can be gifted, sold, or restructured far more easily than the property itself.
For owner-occupiers, there is also a fifth reason. Paying rent from your trading company to a property company you control can be a tax-efficient way to extract cash, provided the rent is set at a genuine market rate and documented properly.
The Tax Position in Plain Numbers
The headline points UK business owners should understand:
- Corporation tax on rental profit: Net rental profit is taxed at 19% to 25% depending on total company profits.
- Capital gains on sale: A company does not pay capital gains tax. Instead, the gain is taxed as part of company profits at corporation tax rates. There is no annual exemption, and indexation allowance was frozen back in December 2017.
- Stamp Duty Land Tax: SDLT applies on purchase. Commercial property uses the non-residential SDLT bands, which start at 0% up to £150,000, 2% between £150,000 and £250,000, and 5% above £250,000. Mixed-use properties also use these bands, which is often more favourable than the residential scale.
- VAT: Some commercial properties come with an option to tax. If you are buying a property where the seller has opted to tax, VAT is charged on the sale price unless you opt to tax yourself and qualify for a transfer of a going concern (TOGC). Get this wrong and you can lose 20% of the purchase price to irrecoverable VAT.
- Extracting profits: Money taken out of the company as dividends is taxed personally on top of corporation tax already paid. The combined effective rate is usually higher than holding the property personally on a small portfolio, which is why the limited company route tends to favour larger holdings and longer time horizons.
How Commercial Mortgages Work for Limited Companies?
Commercial lending is a different world to residential. Underwriting is based on the strength of the business, the deal, and the security, rather than a straightforward income multiple. A few things to expect:
- Loan to value: Typically 60% to 75% for investment property, sometimes higher for owner-occupied premises where the trading business has strong accounts.
- Personal guarantees: Directors are usually asked to give a personal guarantee, often capped at around 20% to 25% of the loan. This is not optional with most lenders.
- Affordability: Lenders look at rental cover for investment deals (interest cover ratios of 130% to 160% are typical) and at EBITDA or net profit for owner-occupied purchases.
- SPV versus trading company: Most lenders prefer a clean Special Purpose Vehicle for property holding, with SIC codes 68100, 68209, or 68320. A trading company holding investment property as a sideline is messier and narrows the lender pool.
- Term and rates: Terms range from 5 to 25 years, with rates priced over Bank Rate or SONIA. Fixed rates are available but the market is smaller than residential.
The lender mix is wider than most business owners realise. High street banks, challenger banks, specialist commercial lenders, and private banks all play in this space, and pricing varies significantly between them.
Working with a commercial mortgage broker is usually worthwhile, because the right lender for your deal depends on the property type, your company structure, the loan size, and how the underwriter views the covenant strength behind the deal.
Deposit, Fees, and What to Budget for
A 30% deposit is a reasonable working assumption for an investment purchase. On top of that, expect:
- Arrangement fee of 1% to 2% of the loan, usually added to the loan rather than paid up front.
- Valuation fee, which on commercial property is paid up front and ranges from around £750 for a small unit to several thousand for a larger asset.
- Legal fees for both your solicitor and the lender’s solicitor, since the borrower pays both sides.
- Broker fee, where applicable, typically 0.5% to 1% of the loan.
- SDLT, payable within 14 days of completion.
A realistic total cost on top of the deposit is around 5% to 7% of the purchase price for a standard commercial deal.
Common Pitfalls
A few that catch business owners out:
- Mixing trading and investment in one company: This creates problems on sale (no Business Asset Disposal Relief on the investment element), restricts lender choice, and complicates accounts.
- Underestimating the cost of getting cash out: Profits left in the company are tax-efficient. Profits extracted to a personal account are not.
- Forgetting Annual Tax on Enveloped Dwellings (ATED): This catches residential property held in companies above £500,000. Pure commercial is outside ATED, but mixed-use and live-work units can pull you in.
- Refurbishment finance: If the property needs work, a standard commercial mortgage may not release funds until completion. Bridging or development finance is often a better fit for the build phase, with a refinance to a term loan once the property is income-producing.
- Personal guarantee insurance: Worth pricing if the guarantee is substantial, since it can protect personal assets if the worst happens.
When It Makes Sense, and When It Does Not?
The limited company route tends to make sense when:
- The property is held for the long term (10+ years).
- Rental profits are significant and would otherwise be taxed at higher or additional rate personally.
- You plan to add further properties over time.
- Owner-occupier rent from a connected trading company is part of the plan.
It tends to make less sense for a single small property held for under five years, especially if you would need to draw the rental income personally to live on.
In that case, the extra layer of corporation tax and dividend tax can eat the saving you were chasing.
The Bottom Line
Buying commercial property through a limited company is a sound default for most business owners with a long-term view, but the structure needs to fit the purpose.
The tax, mortgage, and ownership decisions all interact, and getting them wrong is expensive to unwind once contracts are exchanged.
Speak to your accountant before you commit to a structure, and get the lending side scoped early so you know what is realistic on deposit, LTV, and personal guarantees before you put an offer in.
A short conversation with a specialist broker at the start of the process is usually a better use of time than a long one after the deal is already at risk.
