What Is a Commercial Mortgage – And When Do You Need One?

If you’re buying property for business purposes—whether it’s a retail unit, office space, warehouse, or even a mixed-use building—you’ll likely need a commercial mortgage.

Unlike residential or standard buy-to-let mortgages, commercial mortgages are tailored to properties used primarily for business or investment purposes.


Who Uses Commercial Mortgages?

Commercial mortgages are commonly used by:

  • Business owners buying premises to operate from
  • Investors purchasing commercial property to let to tenants
  • Developers acquiring sites for redevelopment
  • Landlords investing in mixed-use buildings (e.g. flats above shops)

They can also be used to refinance existing commercial property, raise capital, or consolidate debt.


Key Features of a Commercial Mortgage

  • Loan Size – Typically starts at £50,000 with no upper limit (subject to affordability and property value)
  • Deposit – Expect to put down between 25–40%, depending on the property and your circumstances
  • Rates – Interest rates vary depending on your experience, credit profile, business strength, and the asset itself. Rates are often higher than residential due to increased risk
  • Terms – Usually 3 to 25 years, with both capital repayment and interest-only options available
  • Fees – Arrangement, valuation, legal, and broker fees should be factored into your costs

What Do Lenders Look For?

Commercial mortgage lenders will assess:

  • Your business or investment track record
  • The strength of the tenant or lease (if applicable)
  • The property’s value, use, and location
  • Your credit profile and affordability
  • Future potential for rental income or capital growth

Every deal is bespoke. Unlike standard mortgages, there’s no “one-size-fits-all” process—terms are often negotiated case by case.


Why Work With a Specialist Broker?

Commercial lending is a niche market with fewer lenders, more complexity, and a wider range of terms. A specialist broker can:

  • Help package your application professionally
  • Match you with lenders that understand your sector
  • Negotiate competitive rates and terms
  • Guide you through the valuation, legal, and underwriting process

In Summary

A commercial mortgage can be a powerful tool for growing your business or property portfolio, but the stakes are higher, and the process more involved. Whether you’re acquiring your first commercial premises or refinancing a portfolio, the right advice can save you time, money, and stress.
