How do mortgages work for commercial properties?

26th March 2026

By Simon Carr

TL;DR: Commercial mortgages are loans used to purchase business premises or investment properties, typically requiring a higher deposit than residential loans. Borrowers must demonstrate strong business performance or rental potential, and your property may be at risk if repayments are not made.

How do mortgages work for commercial properties?

If you are looking to purchase a warehouse, an office space, or even a retail unit, you will likely need a commercial mortgage. Unlike residential mortgages, which are designed for individuals buying a home to live in, commercial mortgages are tailored for businesses and investors. Understanding how these financial products function is essential for any business owner or property investor in the UK.

At its core, a commercial mortgage is a long-term loan (usually between 3 and 25 years) secured against a property that is not your primary residence. Because the risks associated with business ventures are often higher than those of individuals, the criteria, rates, and terms differ significantly from the mortgages you might be familiar with in the consumer market.

The two main types of commercial mortgages

When asking how do mortgages work for commercial properties, the first step is identifying the purpose of the loan. Lenders generally categorise these into two main types:

  • Owner-occupied mortgages: These are used by business owners who intend to run their own company from the premises they are buying. For example, a local bakery buying their shop or a firm of solicitors purchasing an office building.
  • Commercial investment mortgages: These are for individuals or companies who want to buy a property and then rent it out to another business. This is similar to a residential “buy-to-let” but for commercial units like factories, shopping centres, or office blocks.

The type of mortgage you apply for will influence the interest rate you are offered and the amount of deposit you will need to provide. Investment mortgages are often seen as slightly higher risk by lenders, as they rely on the stability of a tenant’s business to ensure the mortgage is paid.

Deposits and Loan-to-Value (LTV) ratios

In the residential market, it is sometimes possible to find mortgages with a 5% or 10% deposit. However, commercial mortgages work differently. Lenders typically require a much higher equity stake in the property. Usually, you can expect a maximum Loan-to-Value (LTV) of around 65% to 75%. This means you will likely need a deposit of at least 25% to 35% of the property’s purchase price.

If the business is a specialist industry or the property is a unique build, the lender may ask for an even higher deposit. This helps the lender mitigate the risk if they ever need to sell the property to recover their funds. It is important to remember that your property may be at risk if repayments are not made. Failure to keep up with the mortgage could lead to legal action, repossession, increased interest rates, and additional charges from the lender.

How interest rates are determined

Unlike residential mortgages where you can easily compare “best buy” tables, commercial mortgage rates are rarely set in stone. They are usually bespoke and based on the risk profile of the borrower and the property. Lenders will look at your business accounts, your experience in the industry, and the condition of the property itself.

Rates are typically quoted as a “margin” above the Bank of England Base Rate or the Sterling Overnight Index Average (SONIA). For example, if the base rate is 5% and your lender’s margin is 3%, your total interest rate would be 8%. Fixed-rate options may be available for shorter periods, but many commercial loans operate on a variable rate basis.

Eligibility and the credit search process

When you apply for a commercial mortgage, the lender will perform a deep dive into your financial history and the financial health of your business. They will want to see at least two to three years of audited accounts, bank statements, and a detailed business plan. They are looking for “debt serviceability”—proof that your business generates enough profit to comfortably cover the mortgage repayments after all other expenses are paid.

A credit search will be conducted on the business and, in many cases, the directors of the company. A poor personal credit history may not automatically result in a rejection, but it could lead to higher interest rates or a requirement for a larger deposit.

Commercial bridging loans: An alternative

Sometimes, a standard mortgage isn’t the right fit, especially if you need to buy a property quickly at auction or if the property is currently in a state of disrepair. In these scenarios, a commercial bridging loan might be used as a short-term “bridge” until long-term finance can be arranged or the property is sold.

Bridging loans differ from mortgages in several ways:

  • Open vs Closed: A closed bridging loan has a fixed repayment date, usually within a few months. An open bridging loan has no set end date but typically needs to be repaid within 12 to 18 months.
  • Repayments: Most bridging loans do not require monthly interest payments. Instead, the interest “rolls up” and is paid in one lump sum at the end of the term.
  • Speed: These can often be arranged much faster than a standard commercial mortgage.

While bridging loans provide flexibility, they usually carry higher interest rates and fees. It is vital to have a clear “exit strategy” (a plan to repay the loan) before entering into such an agreement.

The application process and fees

The process of securing a commercial mortgage is generally more complex and time-consuming than a residential one. It can take anywhere from six weeks to several months to complete. Here is a general outline of the steps:

  1. Initial enquiry: You provide basic details about the property and your business.
  2. Indicative terms: The lender provides an “Agreement in Principle” or a heads of terms document outlining what they may be willing to lend.
  3. Valuation: The lender will instruct a professional valuer to assess the property. You will usually have to pay for this upfront.
  4. Legal due diligence: Solicitors for both the lender and the borrower will review the property titles and contracts.
  5. Formal offer: Once all checks are passed, a formal mortgage offer is issued.
  6. Completion: Funds are released, and the purchase is finalised.

You should also budget for various fees, including arrangement fees (usually 1-2% of the loan amount), legal fees, and valuation fees. For more information on property standards and legal requirements, you can visit the HM Land Registry website for guidance on UK property registration.

People also asked

Can I get a commercial mortgage as an individual?

Yes, you can apply for a commercial mortgage as an individual, though many people choose to do so through a Limited Company for tax and liability reasons. The lender will still assess your personal financial stability and experience.

What is the minimum loan amount for a commercial mortgage?

Most high-street banks have a minimum loan amount starting around £25,000 to £50,000, though specialist lenders may have different thresholds depending on the property type. Smaller amounts are often handled through business loans rather than mortgages.

Is a commercial mortgage regulated by the FCA?

Generally, commercial mortgages are not regulated by the Financial Conduct Authority (FCA) unless the property is “semi-commercial” and at least 40% of it is used as a residential dwelling by the borrower or their family.

Can I use a commercial mortgage to buy a pub or a hotel?

Yes, pubs and hotels are classic examples of commercial properties. Lenders will focus heavily on the “trading accounts” of the business to ensure it is profitable enough to sustain the debt.

What happens if I miss a payment?

If you miss a payment, the lender will contact you to seek repayment and may charge late fees. Defaulting on the loan can lead to your property being repossessed and will likely make it difficult to secure credit in the future.

Conclusion

Understanding how do mortgages work for commercial properties is the first step toward securing the future of your business or investment portfolio. While the process is more rigorous than buying a home, it offers a way to build equity in an asset rather than paying rent to a landlord. Because every commercial deal is unique, it is often beneficial to speak with a specialist broker who can navigate the various lenders and find a product that suits your specific business needs.

Always ensure you have a robust business plan and a clear understanding of the costs involved. Remember, these are significant financial commitments, and your property may be at risk if you do not keep up with the agreed repayment schedule. Proper planning and professional advice are key to a successful commercial property purchase.
