Buying the unit you rent can make sense if you plan to stay for years and your accounts are strong. Business premises funding usually means a commercial mortgage. You pay a deposit, then repay the rest each month. Lenders are getting stricter, so get the application ready before you start viewing.
Section 01
Should I rent or buy business premises?
There is no single right answer. It depends on how long you will stay, how settled the business is and how much cash you can spare.
According to the British Business Bank, owning your premises has real benefits. You can change the building without asking a landlord. Your property costs become easier to predict. If the value rises, you could make a profit when you sell. You could also rent spare space to another business.
There are downsides too. Buying ties up cash you could use to grow the business. You pay for every repair, and you take on the building's insurance and safety duties. Values can fall. And a building that fits today may not fit if the business grows or shrinks.
So, when does buying tend to make sense? Usually when three things are true. You expect to stay for many years. The building suits the way you work. And paying the deposit would not leave the business short of cash.

What the RICS survey says about premises now
According to the Royal Institution of Chartered Surveyors (RICS), lending on commercial property got tighter over the summer. Its UK Commercial Property Monitor for the third quarter of 2026 was published on 28 October.
-37%credit conditions balance, down from -23% in the second quarter
-15%capital value expectations for the next three months
+38%prime industrial rent expectations for the year ahead
+41%prime office rent expectations for the year ahead
These are net balances. They show how many surveyors expect a rise, minus how many expect a fall. A negative credit balance means more of them see lending getting harder.
Why does this matter to an owner who rents? Rents on better-quality offices and industrial units are still expected to rise. Expectations for property values have softened. That can make buying look better value than it did a year ago.
The picture is not the same everywhere. RICS respondents expect rents on secondary offices and shops to fall. If your unit is older or in a weaker spot, renting may stay the cheaper choice for now.

How business premises funding works
Most owners buy with a commercial mortgage. According to the British Business Bank, it works much like a home mortgage. You pay a deposit, then make monthly repayments at a fixed or variable rate. Terms usually run from one to 30 years.
The version for buying your own trading premises is an owner-occupier mortgage. A commercial buy-to-let mortgage is a different product, for property you rent to another business. Interest rates tend to be higher than on a home mortgage, because the lender takes more risk.
The lender sends its own valuer. It lends a share of the value the valuer sets, not the price you agreed. If the valuation comes in low, you need a bigger deposit or a lower price.
Plan for the costs on top of the deposit:
Stamp duty: In England and Northern Ireland this is stamp duty land tax. Wales and Scotland have their own versions.
Fees: Expect a valuation fee, legal fees and the lender's arrangement fee.
Running costs: Business rates, buildings insurance and repairs all become yours.
Section 04
What lenders check when credit is tight
When lenders tighten, they ask the same questions and expect firmer answers. Here are five of the main ones.
Your trading history
According to the British Business Bank, you usually need accounts for at least the past three years. You also need projected figures for the years ahead.
Whether the repayments are affordable
The lender checks that your profit and cash flow cover the monthly repayment with room to spare. A strong turnover alone will not do it.
Your deposit, and where it comes from
Show the money in the bank and say where it came from. A deposit drawn from the business must not leave it short of working cash.
The property itself
The lender's valuer looks at the building, its condition and how easily it could be sold. A specialist building can be harder to fund than a standard unit.
Any guarantee or extra security
The mortgage is secured on the building. Some lenders also ask the directors for a personal guarantee, so ask early what is expected.
A broker can put the deal to lenders who still want this kind of lending. On advisory deals we take no commission from lenders, so our advice is not shaped by who pays us. You pay us nothing unless a lender on our panel issues an Agreement in Principle. When you are ready, start with business growth finance for your premises.
Section 05
If your deposit is short
A short deposit does not have to end the plan. These are the usual options.
Wait and save: Another year of accounts and a bigger deposit both make the application stronger.
Use other security: According to the British Business Bank, a secured loan against another asset can fund the deposit.
Buy smaller: A smaller unit, or one that needs less work, lowers the deposit you need.
Stay and renegotiate: If you rent, a longer lease or a break clause may give you time to get ready.
