Can I extend the repayment term of my commercial mortgage?

13th February 2026

By Simon Carr

Extending the repayment term of a commercial mortgage is often possible, but it is not guaranteed and requires formal negotiation with your existing lender. Since extending the term reduces the monthly payment but significantly increases the total amount of interest paid over the life of the loan, lenders will perform extensive due diligence on the viability of the underlying business, its current financial health, and the reason for the request. Borrowers must present a compelling business case to justify the restructuring.

Can I Extend the Repayment Term of My Commercial Mortgage?

As a business owner utilising property finance in the UK, managing cash flow is paramount. Situations change—market conditions shift, capital expenditure needs arise, or expected revenues may be delayed. In such circumstances, reducing immediate debt obligations by extending the repayment period of your commercial mortgage can seem like an attractive solution.

The short answer is yes, you can apply to extend the repayment term of your commercial mortgage, but this is viewed by lenders as a fundamental variation to the original loan contract. It requires the lender to reassess their risk exposure and potentially re-underwrite the facility. Unlike residential mortgages where terms may sometimes be adjusted more straightforwardly, commercial lending is inherently bespoke, meaning every request for an extension will be evaluated on a case-by-case basis according to strict criteria.

Understanding Commercial Mortgage Terms and Structure

A commercial mortgage is a long-term loan secured against commercial property (such as offices, warehouses, retail units, or industrial premises). These loans typically range from 5 to 25 years. The term dictates how long you have to repay the principal loan amount, plus interest.

When you initially took out the mortgage, the term was set based on several factors:

  • The useful economic life of the property.
  • The business’s projected cash flow and profitability over that period.
  • The borrower’s age (if relevant to the end date of the loan).
  • The lender’s maximum lending criteria for that asset class.

Extending the repayment term means spreading the outstanding principal balance across a longer timeframe. While this naturally reduces the size of each periodic repayment, it introduces additional years during which interest accrues, increasing the total cost of borrowing significantly.

Reasons for Seeking a Term Extension

Lenders need to understand the underlying drivers behind the request. Simply wanting lower payments is insufficient; there must be a genuine, documented business reason. Common justifications for needing to extend the repayment term include:

1. Improving Short-Term Cash Flow

If the business is undergoing a temporary dip in revenue or facing unexpected high operational costs, lowering the mortgage payment commitment can free up vital working capital, allowing the business to navigate the downturn without defaulting on core debt obligations.

2. Funding Growth and Investment

A business may require capital for expansion, purchasing new equipment, or investing in marketing. By reducing the monthly mortgage burden, more funds can be retained and channelled into growth initiatives, ultimately aiming to increase profitability in the long run.

3. Managing Covenant Compliance

Commercial loans often include financial covenants (agreements about minimum profitability, asset cover ratios, etc.). If the business is close to breaching these covenants, reducing the mandated debt service requirement through a longer term can help the business maintain compliance and avoid default situations, which carry severe consequences.

4. Changing Exit Strategy

If the original plan involved selling the property or refinancing by a specific date, and external factors (such as a slow property market or delayed planning permission) have affected this timeline, an extension is necessary to manage the debt until the new strategy can be executed.

The Lender’s Perspective: Why Approval Isn’t Guaranteed

Lenders approach term extension requests with caution because they fundamentally increase the overall risk profile of the loan. When assessing your request, the lender will focus on three key areas:

1. Affordability and Debt Service Coverage Ratio (DSCR)

While an extension aims to improve affordability, the lender must be satisfied that the business remains stable and viable, especially considering the higher total interest payable. They will recalculate the DSCR based on your current profitability and the new proposed lower repayment amount to ensure a comfortable margin. If the business is already struggling severely, the lender may view the extension as merely delaying the inevitable and might seek alternative solutions (like partial repayment or collateralisation) instead.

2. Loan-to-Value (LTV) Ratio

The security for the loan is the property. If the property’s value has decreased since the loan was taken out, the LTV ratio increases. Extending the term, especially if it pushes the repayment schedule closer to the typical end-of-life assessment for that property type, can make the lender uneasy about the adequacy of their security. They may require an updated valuation, and if the LTV is too high, they might decline the request or require additional security.

3. Business Viability and Track Record

The lender needs assurance that the underlying issue causing the request is temporary and that the extension genuinely allows the business to recover or grow, rather than simply masking insolvency. They will scrutinise recent accounts, management information (MI), and future projections heavily.

If the lender determines that the business is fundamentally unviable or that the collateral is insufficient, they are likely to decline the extension and explore other options, which may include forbearance, seeking additional guarantees, or, in severe cases, pursuing enforcement action.

The Process of Extending Your Commercial Mortgage Term

Initiating a term extension is not an informal phone call; it is a formal loan restructuring process that typically follows several steps:

1. Initial Communication and Assessment

Contact your existing lender or mortgage advisor as soon as you anticipate needing an extension. Explain the situation clearly, providing concise context about why the extension is necessary and what your revised financial strategy is. Early communication is crucial; waiting until you have missed a payment drastically harms your negotiation position.

2. Formal Application and Documentation Submission

The lender will require a comprehensive package of information to assess the risk of the proposed extension. This package usually includes:

  • A detailed explanation of the business rationale for the extension.
  • Up-to-date management accounts (usually covering the last 12 months).
  • Latest statutory accounts (usually 2–3 years).
  • A revised cash flow forecast covering the extended term, demonstrating future affordability.
  • An updated business plan outlining growth strategies or recovery measures.
  • Personal and business credit reports.

Lenders will rigorously assess your credit history during this process, as evidence of poor financial management will heavily prejudice your application.

3. Underwriting and Due Diligence

The lender’s underwriting team will review the documentation. They may commission a new professional valuation of the secured property, which the borrower usually pays for. They will model the impact of the extension on the loan’s overall performance and profitability.

4. Agreement and Legal Finalisation

If the extension is approved, the lender will issue a formal offer letter detailing the new repayment schedule, any revised interest rates, and all associated fees. This will then be formalised through new legal documentation (often called a Deed of Variation or Supplemental Mortgage Deed), which must be reviewed by legal professionals and signed by all parties.

Costs Associated with Term Extensions

While the immediate benefit of a term extension is reduced monthly cash outlay, it is vital to understand the comprehensive financial costs involved:

1. Higher Total Interest Paid

This is the most significant cost. If you extend a £500,000 mortgage from 15 years to 25 years, the amount of time that interest compounds is dramatically increased, potentially adding tens of thousands of pounds—or more—to the total repayable amount.

2. Arrangement and Administration Fees

Lenders often charge an arrangement fee for processing a loan variation. This fee covers their administrative and underwriting costs. It can be a fixed amount or a percentage of the outstanding balance, and it is sometimes added to the principal loan amount.

3. Valuation and Legal Fees

As noted, you may be required to pay for a new property valuation. Additionally, the borrower is typically responsible for the lender’s legal costs associated with drafting and registering the Deed of Variation.

4. Potential Rate Increases

Depending on the current financial market and the perceived risk increase, the lender may use the term extension as an opportunity to adjust the interest rate upwards, especially if the original terms were highly competitive or fixed rates have expired.

Alternatives to Extending the Repayment Term

If your existing lender is unwilling to grant an extension or if the proposed terms are too punitive, you have several alternatives to explore:

1. Refinancing with a New Lender

Refinancing involves taking out a completely new commercial mortgage with a different provider over a longer term. This allows you to reset the clock and potentially secure better overall terms, although it will trigger Early Repayment Charges (ERCs) from your current lender if you are still within a fixed period.

  • Pros: Potential for a lower interest rate, maximum possible term extension (up to 25 or 30 years).
  • Cons: Expensive ERCs, new legal and valuation fees, and a full application process (which takes time).

2. Seeking a Capital Repayment Holiday

Instead of extending the whole term, some lenders may offer a short-term capital repayment holiday (e.g., 6–12 months). During this period, you pay only the interest, which significantly reduces the monthly payment temporarily, allowing the business to stabilise. The principal repayments are then typically reinstated at a higher level or the term is marginally extended to cover the missed capital.

3. Asset-Based Lending or Bridging Finance

If the need for immediate cash flow is critical and short-lived (e.g., 6–18 months), you might secure a temporary injection of capital through other means, such as asset finance (if you have business assets) or a bridging loan. A bridging loan is a short-term solution used to quickly bridge a financial gap until longer-term funding is secured or an asset is sold. While effective for short-term needs, these often have higher interest rates.

It is crucial to remember that if you utilise property as security for any loan, including refinancing or bridging finance, Your property may be at risk if repayments are not made. Defaulting can lead to legal action, repossession, increased interest rates, and additional charges.

4. Injecting Director/Shareholder Capital

If possible, injecting personal funds or securing external equity investment can solve cash flow problems without restructuring the secured debt, which is often the cleanest solution if available.

Compliance and Responsible Lending Considerations

Under UK regulations, commercial lenders must operate within the framework of responsible lending. While the requirements are less stringent than those for regulated consumer mortgages, lenders must still ensure that any restructured agreement is sustainable for the borrower. If a lender agrees to an extension, it should be because they genuinely believe the business will be able to service the revised debt obligations.

If you are struggling with debt or believe your business is at risk of insolvency, seeking independent financial advice is critical. Organisations like the Government’s Business Support Helpline or independent debt charities can provide guidance on structuring sustainable finance strategies for SMEs in distress.

People also asked

How long can I typically extend a commercial mortgage term?

The maximum extension is highly dependent on the initial term remaining and the lender’s maximum duration, which is typically 25 years in total, though some specialist lenders may go up to 30 years. The lender will also consider the residual economic life of the physical property; they will rarely extend the term past the point where the property is considered fully depreciated or requires substantial refurbishment.

What happens if my lender refuses to extend the term?

If your lender refuses, you must immediately seek alternative financing options, such as refinancing the loan with a new lender who is willing to offer a longer term, or exploring temporary finance solutions. You should also review your business expenditure to see if sufficient cost savings can be implemented to meet the current repayment schedule.

Will extending the term affect my credit rating?

Simply applying for a variation may result in a soft or hard credit search, depending on the lender, which could temporarily impact your credit score. However, successfully negotiating and adhering to the new, extended terms will be viewed positively, demonstrating sound financial management. Failing to secure the extension and subsequently missing payments would have a severe negative impact on your credit history.

Is extending the term cheaper than refinancing?

Extending the term with your existing lender generally involves lower upfront costs (fewer legal fees, no ERCs if you’re outside the fixed rate period, potentially lower arrangement fees) than refinancing with a new provider. However, if the new lender can offer a significantly lower interest rate, refinancing might be cheaper in the long run, despite the initial high costs.

Do I need a commercial mortgage broker to apply for an extension?

While you can apply directly to your current lender, using an experienced commercial mortgage broker is highly recommended. A broker understands the documentation lenders require for variations, can help structure a compelling business proposal, and can advise on whether refinancing offers a better value solution than remaining with your current provider.
