Can I use a commercial mortgage to expand my business?

13th February 2026

By Steve Walker

A commercial mortgage is a dedicated financial tool specifically designed to enable UK businesses to purchase or refinance commercial property, making it one of the most common and effective methods for facilitating business expansion. Whether your business needs larger premises, a new operational base, or wishes to purchase property currently being leased, a commercial mortgage provides the necessary long-term capital required for significant property investment.

Can I Use a Commercial Mortgage to Expand My Business?

Absolutely. A commercial mortgage is arguably the cornerstone of property-related business expansion in the UK. Unlike residential mortgages, these loans are structured around the commercial viability and financial health of the applicant business, rather than personal income.

Business expansion often necessitates a change in location or an increase in operational space. Relying on rented premises can limit long-term control and financial stability. By acquiring property through a commercial mortgage, businesses gain an asset that can appreciate in value, offering greater security and flexibility for future growth.

Understanding Commercial Mortgages for Growth

Commercial mortgages are long-term financial agreements, typically spanning 15 to 25 years, used to purchase property that will be used for commercial purposes. They fall into two main categories relevant to business expansion:

  • Owner-Occupier Mortgages: These loans fund the purchase of property that the business intends to occupy and use for its core operations (e.g., buying a warehouse for manufacturing, or an office block for administration).
  • Commercial Investment Mortgages: These are used when a business or investor purchases property specifically to rent out to other commercial tenants, generating rental income (e.g., acquiring a retail unit complex). While not directly expanding the operational space, it expands the business’s investment portfolio and revenue streams.

The structure of the loan is tailored to the business environment. Lenders will assess not just the value of the property, but critically, the ability of the business to generate sufficient profit to meet the mortgage repayments.

Key Ways a Commercial Mortgage Supports Expansion

Using commercial finance strategically can unlock several key avenues for growth that would be impossible to achieve through cash reserves or short-term lending alone.

Purchasing Larger Premises

The most immediate use of a commercial mortgage is upgrading to a larger operational base. As a business grows, capacity constraints—be they limited retail floor space, insufficient storage, or overcrowded offices—can stifle potential. A commercial mortgage allows a business to relocate to premises that fit current needs while offering room for future scaling.

This expansion might include:

  • Acquiring a significant factory or manufacturing plant.
  • Moving a service-based company into a high-specification office building.
  • Buying a larger retail unit in a high-footfall location.
  • Consolidating multiple leased locations into one owned, centralised headquarters.

Acquiring Investment Property for Diversification

For established businesses, expansion doesn’t always mean bigger premises; it can mean diversifying assets. A commercial investment mortgage allows a business to use its borrowing power to purchase properties specifically for rental income. This diversification can create a stable, secondary income stream, strengthening the overall financial foundation of the company.

Funding Specialised Assets

Many businesses operate within highly specialised sectors, requiring bespoke properties. Examples include hotels, care homes, farms, industrial estates, or complex medical facilities. Lenders often provide specific types of commercial mortgages tailored to these unique property assets, recognising the specific income models associated with them.

Eligibility and Application Process for Expansion Finance

While the benefits of property ownership are clear, securing a commercial mortgage is a rigorous process. Lenders must be satisfied that the business is financially robust and that the property investment is sound.

Financial Requirements and Loan-to-Value (LTV)

Commercial mortgages generally operate on stricter Loan-to-Value (LTV) ratios than residential loans. While residential LTVs can reach 90% or even 95%, commercial mortgages typically require the business to provide a deposit representing 25% to 40% of the property value. This means the LTV usually ranges from 60% to 75%.

Key financial criteria assessed include:

  • Trading History: Most lenders prefer businesses with at least two or three years of profitable trading accounts.
  • Affordability: The business must demonstrate that its cash flow is strong enough to comfortably cover the new mortgage payments, often requiring significant headroom above the required amount.
  • Deposit Source: Lenders will verify that the deposit funds are legitimate and accessible.

The Importance of a Robust Business Plan

When applying for a commercial mortgage specifically for expansion, the lender needs to understand the strategic rationale behind the purchase. This requires a detailed business plan that clearly outlines:

  • The need for expansion (e.g., projected increase in headcount, turnover, or production capacity).
  • How the new property will contribute to increased profitability.
  • Detailed financial forecasts (profit and loss, cash flow projections) for the next 3–5 years, demonstrating the ability to meet the debt obligations.
  • Market analysis showing demand for the business’s services or products.

Checking Your Business Credit Health

A crucial step in securing favourable commercial finance terms is ensuring the business’s financial track record and credit rating are impeccable. Lenders will perform extensive due diligence on both the company and the directors involved.

It is essential to understand exactly what lenders see before applying. Maintaining clear records of existing debt, avoiding defaults, and ensuring all company filings are up to date with Companies House are vital preparation steps.

Key Risks and Compliance Considerations

While commercial mortgages are powerful tools for expansion, they carry significant risk and require careful management.

Security and Personal Guarantees

Unlike unsecured business loans, commercial mortgages are secured against the property being purchased. This means if the business defaults on the loan, the lender has the right to repossess the property to recover the outstanding debt. Furthermore, lenders often require Personal Guarantees (PGs) from the business directors. A PG means that if the company cannot meet the debt obligations, the directors are personally liable for the repayment, potentially putting personal assets (like your primary residence) at risk.

Interest Rate Volatility

Commercial mortgage interest rates are often variable or track the Bank of England base rate. Fluctuations in the market can significantly impact monthly repayment costs. While fixed-rate options are available, they often come at a premium or only cover an initial period (e.g., 2 or 5 years), after which the rate reverts to a standard variable rate.

Potential for Additional Charges

Setting up commercial finance involves various non-refundable costs, including valuation fees, legal fees, and arrangement fees (which can often be 1% to 3% of the loan amount). These must be factored into the overall cost of the expansion.

Alternatives to Commercial Mortgages for Business Expansion

Depending on the speed and nature of the expansion, a long-term commercial mortgage may not always be the optimal choice. Other specialised financial products can facilitate quicker transactions or different types of assets.

Commercial Bridging Finance

Bridging loans are short-term, high-interest financial solutions typically used when a business needs to complete a property purchase quickly—such as buying property at auction, or acquiring premises before selling their current location.

If you are using a bridging loan to secure a property before longer-term commercial mortgage finance is arranged (the ‘exit strategy’):

  • Bridging loans are fast, but costly. Interest usually accumulates, or ‘rolls up,’ into the final repayment amount, rather than being paid monthly.
  • The term is typically 6 to 18 months, requiring a clear, proven exit strategy (usually the sale of another asset or the approval of the commercial mortgage) before the loan matures.

It is vital to understand the risks associated with this type of short-term financing. Your property may be at risk if repayments are not made. Consequences of default can include legal action, increased interest rates, additional charges, and ultimately, repossession of the secured asset.

Secured Business Loans

If the expansion does not involve purchasing property but requires significant capital expenditure (e.g., buying new machinery, large IT upgrades, or extensive property refurbishment), a secured business loan might be more appropriate. These are usually shorter term than mortgages and can be secured against existing property assets or other valuable company assets.

Refinancing Existing Commercial Property

If the business already owns commercial property, refinancing the existing mortgage to release equity can be a low-risk way to fund expansion. This involves taking out a new mortgage, often for a larger amount, and using the difference in capital to fund the business growth strategy. This option avoids the initial cost and risk of acquiring entirely new premises.

Strategic Considerations When Seeking Expansion Capital

To successfully leverage a commercial mortgage for expansion, several strategic decisions must be made early in the process:

The Lease vs. Buy Calculation

While ownership offers control and potential asset appreciation, buying property carries significant burdens, including maintenance, repairs, and capital commitment. Businesses must rigorously analyse whether the long-term benefit of ownership outweighs the flexibility and lower initial capital strain of continuing to lease.

Choosing the Right Repayment Method

Commercial mortgages typically offer two main repayment structures:

  • Capital and Interest (Repayment): Each monthly payment reduces both the principal debt and covers the interest accrued. This ensures the loan is fully repaid by the end of the term.
  • Interest-Only: Monthly payments only cover the interest. This keeps monthly costs low but requires the borrower to have a clear strategy (the ‘exit strategy’) for repaying the entire principal sum when the mortgage term ends. This is higher risk if the repayment source is uncertain.

Engaging with Specialist Brokers

The commercial mortgage market is vast and complex, often involving bespoke agreements rather than standardised products. Working with a specialist commercial finance broker who understands the needs of an expanding UK business is highly advisable. A broker can access deals from various specialist lenders that are not available on the high street and help structure the application to highlight the business’s strengths.

People also asked

What is the minimum deposit required for a UK commercial mortgage?

Generally, lenders require a minimum deposit of 25% of the property purchase price, meaning the maximum Loan-to-Value (LTV) is usually 75%. For highly specialised properties or businesses perceived as higher risk, the required deposit may increase to 30% or 40%.

Can a new start-up business secure a commercial mortgage?

It is significantly harder for new start-ups (less than two years trading) to obtain a standard commercial mortgage, as lenders rely heavily on proven profitability and trading accounts. However, some specialist lenders may consider applications if the directors have strong industry experience, significant personal collateral, or if the property is a strong investment asset with guaranteed rental income.

Are commercial mortgage interest rates higher than residential rates?

Yes, commercial mortgage rates are typically higher than residential rates because commercial lending is perceived as carrying a greater risk. The rates are based on the profitability of the business and the property type, not stable employment income, making the lending criteria stricter and the pricing higher.

How long does it take to complete a commercial mortgage for expansion?

The completion timeline is highly variable but generally much longer than a residential mortgage. From application to completion, it can typically take between 8 to 16 weeks, depending on the complexity of the property valuation, the business structure, and the legal due diligence required by the lender.

What is an acceptable debt service coverage ratio (DSCR) for lenders?

The DSCR measures a business’s cash flow against its debt obligations. Most UK commercial lenders look for a DSCR comfortably above 1.25x. This means the business’s net operating income must be at least 25% higher than the scheduled debt payments, ensuring there is a safety buffer.

Conclusion: Making the Strategic Decision to Use a Commercial Mortgage to Expand Your Business

For UK businesses ready to transition from renting to ownership, or those requiring significant capital expenditure on premises, a commercial mortgage is a necessary and highly effective tool. It converts rent payments into asset ownership, providing long-term security and greater operational control.

However, successful expansion using this finance requires meticulous planning, strong cash flow projections, and a complete understanding of the associated financial liabilities, including the potential requirement for personal guarantees and the risks tied to interest rate fluctuations. By conducting thorough due diligence and working with experienced finance professionals, businesses can leverage commercial mortgages to achieve sustainable, long-term growth.
