What are Commercial Mortgages?
Commercial mortgages are loans used to either buy or refinance property that’s basically used for business purposes rather than residential purposes. Think of things such as offices, shops, warehouses, and factories etc. If the property is linked to trade, investment, or income generation, it normally comes under the heading of a commercial mortgage.
These types of mortgages aren’t quite the same as the ones you’d get for a residential property. The loan sizes are usually bigger, the terms can be more flexible and the way lenders assess an application is more detailed. Lenders will not only look at you personally and your financial position but also at the property itself – how much income could it generate, what it’s worth now and how that value might vary over time.
In summary, a commercial mortgage gives you the financial backing to secure the right kind of property for your business, whilst giving the lender confidence that you can afford the payments and ultimately, the deal makes sense for both sides.
Key Features of Commercial Mortgages
Commercial mortgages work differently to residential home loans. Since a commercial mortgage is designed specifically for business use, lenders’ can have varying approaches to how they assess things such as affordability etc.
However, the factors below are the most common criteria and features used across most lenders when assessing viability and terms etc for commercial mortgages UK:
Loan size and purpose
These mortgages are usually taken out for much larger sums than a standard residential loan. They’re meant for properties that support a business or generate income—whether that’s buying new premises, refinancing something you already own, or investing in a rental block.
Deposit requirements
You’ll normally need to put down a more substantial deposit than you would with a residential mortgage. Lenders often ask for somewhere in the region of 25–40% of the property’s value. The exact figure depends on the property type and how risky the lender sees the deal.
Interest rates and terms
Because commercial lending is riskier for banks, the interest rates tend to be higher than residential ones. Terms can vary a lot – some are as short as three years, while others run for 20 years or more. Fixed and variable rate mortgage options will most certainly exist, as well as possibly options for tracker and interest-only options.
How commercial lenders assess applications
Commercial mortgages are assessed very differently to residential mortgages. Whilst your personal financial situation is still relevant, lenders will look closer at the property itself, its earning potential, and the long-term stability of your business. Crucial documents such as Cash-flow Forecasts and Business Plans often carry a lot of weight in the overall decision as they will help demonstrate to potential lenders that you can afford and ideally grow once the new commercial mortgage has been put in place.
Flexibility
One of the main advantages of a commercial mortgage is that it doesn’t always come as a rigid, one-size-fits-all product. In many cases, the commercial lenders are willing to shape the mortgage terms around your circumstances. That might mean stretching or shortening the loan term, putting together a repayment plan that works with your cash-flow, or being open to a wider range of property types if the business case stacks up sufficiently.
For a lot of UK business owners, that flexibility is what makes these mortgages so useful and beneficial to their businesses. These mortgages can create opportunities to buy or refinance commercial property that can support growth, stability and future plans. The crucial element is knowing the basics before you commit and jump in head first, so you can be confident you’re choosing the right option for your business.

Types of Commercial Mortgages
There isn’t just one type of commercial mortgage. Businesses in the UK have a range of options, and the right choice depends on what you’re seeking to achieve. Below are some of the most common types you’ll come across.
Traditional Commercial Mortgages
This is the straightforward option most people think of first. Offered by High Street banks and other commercial lenders, these mortgages usually come with fixed or variable interest rates and regular monthly repayments. They’re paid back over a set term, much like a standard home mortgage, but tailored to business use.
Small Business Loans (Government-Backed)
Smaller businesses sometimes have access to loans that are supported by the government. These Small Business Loans are designed to make borrowing easier, often with lower deposit requirements and more flexible terms than a traditional mortgage. Commonly referred to in the United States and less so in the UK as SBA Loans, for many entrepreneurs, they can be a more realistic way to secure funding.
Bridging Loans
A bridging loan does exactly what its name suggests – it helps cover the gap between buying a new property and selling an existing one. They are short-term funding solutions, but they can be incredibly useful if you need to move quickly and can’t wait for a sale to complete or other longer-term funding solutions to be secured.
Development Finance
If you’re building a property project from the ground up, or renovating a property, then a development finance loan is often the right route. These loans also work very differently to other property loans – since instead of getting the money upfront in one lump sum, the funds are released in stages as the project build progresses, which helps keep everything on track.
Mezzanine Loans
Mezzanine finance is basically a top-up loan. Imagine you’ve already secured a main mortgage, but it doesn’t quite cover everything you need. Maybe the purchase price is a little higher than expected, or you’ve got building work and improvements to fund. Rather than walking away from the deal, mezzanine lending can fill that gap.
It sits in between a standard mortgage and equity investment, which is why people often call it “in-between” finance. The money can be used to finish off a purchase or to push a project over the line when other funding sources fall short.
Yes, the costs are usually higher than a first mortgage, but many businesses see it as worth it. Without that extra bit of funding, the deal might not happen at all. For a lot of borrowers, mezzanine finance is the difference between a project stalling and a project moving ahead on schedule.
What Lenders Look At When You Apply
Getting a commercial mortgage isn’t just about asking for the money and waiting for an answer. Lenders dig into a few different areas before they decide. They want to know the deal makes sense and that you’ll be able to keep up with the repayments. Here’s how they usually look at it.
The property itself
The building you’re buying plays a huge part. A lender will check its value, where it’s located, and what shape it’s in. They’ll also think about how easy it would be to sell if they ever needed to. On top of that, they’ll look at its potential to bring in income – because a shop on a busy high street is very different from an empty warehouse in the middle of nowhere.
Your finances
Next, they’ll want to know how solid you are financially. That means reviewing key things such at credit history, business accounts, tax returns and cash-flow forecasts. However, it isn’t just all about the numbers – lenders will also want to see if you’ve got suitable and relevant experience. If you’ve managed property before, or run a successful business, it gives them more confidence that you know what you’re doing.
How much you’re borrowing compared to the property’s value (LTV)
Lenders will very rarely cover the full price of a commercial property. They’ll expect you to put down a deposit yourself, usually more than with a residential mortgage. The lower the loan amount, the less risk they’re taking.
Whether the property can pay for itself (DSCR)
In simple terms, the lender wants to be sure the property brings in enough money to cover the repayments. If the income is tight, it makes them nervous. If it’s comfortably higher than the repayments, you’re in a good position. DSCR stands for Debt Service Coverage Ratio.
Your deposit
Finally, there’s the deposit. You’ll normally need to put down somewhere between 20% and 30% of the purchase price for a commercial mortgage. The exact amount of deposit needed will depend on things such as your financial track record and the type of property you’re buying. Ultimately, the bigger the deposit you can put down the better interest rate you’ll be able to secure, since the represents less risk for the lender.

Managing a Commercial Mortgage
Getting a commercial mortgage over the line is a big step in itself, but this is only the start of the journey, not the end! The real challenge is looking after it properly – any mortgage isn’t just a number on paper – it’s a commitment that runs for many years, sometimes decades. How you manage the mortgage and commercial property it will affect your cash flow, your credit record, and ultimately the success of your business.
Keep up with the repayments
It sounds obvious, but it’s worth saying: never let payments slide. One missed instalment can quickly snowball into fees, penalties, and a mark on your credit file. Many owners set up a direct debit just to take the risk of forgetting out of the equation. Think of it like paying your staff or suppliers—it has to happen on time, every time.
Take care of the property
The property is more than just four walls – it’s the backbone of the deal. If it starts falling apart, you’re not only losing value but also losing appeal to tenants and buyers. Landlords who ignored small repairs end up with empty units because tenants moved out and it’s no longer appealing to secure new tenants. On the flip side, a well-kept building can often command higher rent and attract better tenants. Regular maintenance isn’t a cost – it’s protection for your investment and therefore an absolute must.
Know when to refinance
Markets move. Interest rates go up and down. Your own business might look stronger two or three years in than it did on day one. That’s when you should be considering to potentially refinance commercial property. For example, client’s can often cut their repayments by nearly a third just by switching when interest rates dropped. Keeping an eye on opportunities like that can save serious money over the life of the loan.
Speak up if things get difficult
Every business hits rough patches. Cash flow tightens, sales dip, or unexpected bills land on your desk. If that happens, don’t keep quiet. Lenders would rather you pick up the phone early than let the arrears pile up. In many cases, they’ll agree to tweak the structure of the loan – stretching payments, changing terms – so you can get through a tough spell without the risk of default.

Do I need to be VAT registered to apply?
