A commercial property mortgage is a loan secured against a property that is not your primary residence. It is used to buy premises for your own business or to purchase a property to let out to other businesses. In the current 2026 market, these loans are essential tools for SMEs looking to move from renting to owning their own workspace.
How does a commercial property mortgage work?
Unlike residential loans, commercial mortgages are not strictly regulated by the FCA unless they involve an element of residential use (known as semi-commercial). The loan is secured against the property, and the lender takes a legal charge over the title.
We find that lenders categorise these into two main types: owner-occupied and investment. The criteria for each vary significantly, especially regarding how you prove you can afford the monthly repayments.
The two main types of commercial finance
- Owner-Occupied Mortgages: You buy a property to run your own business from. Lenders look at your trading accounts and EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation) to ensure the business can cover the debt.
- Commercial Investment Mortgages: You buy a property to lease to other businesses. Here, the lender prioritises the 'covenant strength' of your tenants and the lease length over your personal income.
What are the costs involved in 2026?
Commercial rates are usually priced at a margin above Bank Rate (which stood at 3.75% when this guide was published in June 2026). Every case is priced individually based on risk, and the figures below are illustrative only.
| Cost Element | Typical Range/Amount |
|---|---|
| Deposit | 25% to 40% of property value |
| Arrangement Fees | 1% to 2% of the loan amount |
| Valuation Fees | £500 to £5,000+ (Size dependent) |
| Legal Fees | £2,000 to £10,000+ |
| Interest Rates | Priced individually at a margin above Bank Rate (illustrative, not a quote) |
Pro Tip: Lenders often charge a 'commitment fee' just to issue a formal offer. Always ensure your mortgage adviser has vetted the deal before you pay these non-refundable costs.
Why do businesses choose commercial mortgages now?
Following the FCA mortgage reforms of early 2026, there is more protection for small business owners regarding how lenders handle defaults. This has increased confidence for practitioners like doctors, retailers, and light industrial firms to stop paying rent and start building equity.
Many businesses are using our remortgage services to release capital from their existing premises to fund expansion or invest in green energy upgrades, which are increasingly required by 2026 environmental regulations.
What documents do you need for an application?
Lenders in 2026 are highly data-driven. To secure the best mortgage rates, you will generally need to provide:
- Two to three years of certified accounts.
- Business tax returns (SA302s for partners).
- A current business plan and three-year projections.
- A comprehensive asset and liability statement for all directors.
- Lease agreements if there are existing tenants.
If you are a first-time buyer in the commercial sector, you may be asked for a larger deposit, often closer to 35%, to mitigate the lack of a commercial track record.
How is affordability calculated?
Lenders use the Debt Service Coverage Ratio (DSCR). They want to see that your business profit (or rental income) is significantly higher than the annual mortgage repayments. Typically, they look for a ratio of 1.25 or 1.5. This means if your mortgage costs £10,000 a year, they want to see at least £12,500 in available profit.
Pro Tip: In a higher-rate environment like 2026, lenders may 'stress test' your application at 9% or 10% interest rates to ensure your business remains viable if rates rise further.
What I tell my clients
"Commercial finance is much more about the 'story' than residential lending is. I tell my clients that a bank doesn't just look at their credit score; they look at the sector health and the business's longevity. If you operate in a high-risk sector like hospitality, expect more questions and a potentially lower LTV. Getting your accounts in order six months before you apply is the single best thing you can do to avoid a rejection."
