How Does a Commercial Mortgage Work in the UK?

A commercial mortgage is a long-term loan used to purchase or refinance property for business or investment purposes. Instead of borrowing to buy a home, the finance is secured against a commercial property such as an office, shop, warehouse, industrial unit, factory, medical premises or certain mixed-use properties.The basic principle is straightforward: you contribute some […]

Remortgaging a commercial property can be worth considering when your existing finance no longer fits your business, investment or property plans. You might be approaching the end of your current mortgage deal, looking for a different interest rate, wanting to release equity or needing additional funds for business growth. However, the right time to remortgage is not necessarily the moment you see a lower rate elsewhere. Commercial refinancing involves valuation, lender assessment, legal work and potentially early repayment charges, so the overall cost and benefits need to be considered together. A commercial remortgage replaces existing finance secured against a commercial property with a new mortgage or refinancing facility. NatWest describes commercial remortgaging as refinancing secured against commercial real estate and notes that it can be used to save money or raise finance for business purposes.  For business owners, landlords and property investors, the key question is therefore not simply “Can I remortgage my commercial property?” but “When does remortgaging make financial and strategic sense?” This guide explains the main situations when you should consider remortgaging a commercial property, what to check first, how early you should start, what costs can apply and how to prepare for the application. What Does Remortgaging a Commercial Property Mean? A commercial remortgage involves replacing an existing mortgage secured against a commercial property with new finance. The property itself generally remains in the same ownership. The new finance is used to repay the existing borrowing, with the new lender taking security over the property. Commercial properties that may be considered for refinancing can include: Offices Warehouses Industrial units Retail premises Workshops Business premises Commercial investment properties Certain semi commercial or mixed use properties The exact options depend on the property, borrower, existing finance and lender criteria. The Commercial Mortgage Guy explains that commercial property finance can be used to refinance existing property, release equity and support business expansion.  When Should You Consider Remortgaging a Commercial Property? There are several circumstances where reviewing your existing commercial mortgage could be worthwhile. 1. Your Current Commercial Mortgage Deal Is Coming to an End One of the most obvious times to consider remortgaging is when your current fixed or agreed rate period is approaching its end. You do not necessarily need to wait until the exact expiry date before starting the process. In fact, beginning early can give you time to review the market, understand your existing lender's options and deal with valuation and legal requirements. NatWest's current commercial mortgage information explains that borrowers can review their options when an agreed fixed or variable rate period comes to an end, while its commercial remortgage service allows an existing commercial loan to be replaced with new finance.  The important point is to avoid leaving the decision until the last minute. A commercial remortgage can involve more detailed underwriting than a straightforward residential rate switch, particularly when the property or company structure is complicated. 2. You Want to Review Your Interest Rate Interest rates can change over time, and your financial circumstances may also have changed since you originally took out the mortgage. If your current deal is no longer competitive, you may want to investigate whether another lender could offer a more suitable structure. However, do not judge the potential saving from the interest rate alone. You should also consider: Early repayment charges Arrangement fees Valuation fees Legal costs Broker fees The remaining mortgage term The proposed new term For example, suppose your existing commercial mortgage is £500,000 and the current interest rate produces annual interest costs of £30,000. If a new arrangement could reduce the annual interest cost, that may look attractive. But if switching involves £15,000 of refinancing costs, the saving needs to be considered over the expected period you will keep the new mortgage. The calculation is more important than simply comparing two headline rates. 3. Your Property Has Increased in Value Another reason to review your commercial mortgage is that the property may now be worth more than when you originally borrowed against it. Suppose your company bought a commercial property for £800,000 and borrowed £560,000. The original LTV was: £560,000 ÷ £800,000 = 70% If the property is now worth £1 million and the mortgage balance has fallen to £500,000, the current LTV would be: £500,000 ÷ £1,000,000 = 50% That is a significant change in the relationship between the property's value and the outstanding debt. A lower LTV can potentially improve the range of refinancing options available, although it does not guarantee a particular rate, lender or borrowing amount. The new lender will normally want to establish the property's current value as part of the assessment. 4. You Want to Release Equity From the Property Commercial remortgaging can potentially be used to release some of the equity built up in a property. This can be relevant when a business wants to access capital without selling the property. For example: Property value: £1,000,000 Existing mortgage: £450,000 Potential new mortgage: £600,000 Potential additional borrowing: £150,000 The additional borrowing could potentially be used for an approved purpose such as: Business expansion Purchasing equipment Refurbishment Working capital Purchasing another property Investment in the business Releasing capital from an investment property The amount available depends on lender criteria, affordability, property value and the proposed use of the funds. NatWest specifically identifies raising finance for a business as one potential use of commercial remortgaging.  It is important to remember that releasing equity increases the amount secured against the property. The additional borrowing therefore needs to be considered alongside the expected business or investment benefit. 5. Your Business Is Growing Business growth can change your financing requirements. When you originally took out the commercial mortgage, you may have only needed enough finance to purchase your premises. Several years later, the business could be larger and require additional capital. For example, a manufacturing company may have: Increased turnover Taken on additional staff Expanded its customer base Purchased new machinery Added another operating site Increased stock requirements Started considering another property If the existing commercial property has sufficient equity, remortgaging may be one potential way of reviewing the company's property backed borrowing. The lender will still need to assess affordability and the purpose of the additional finance. 6. You Want to Buy Another Commercial Property Some businesses consider remortgaging an existing property to help fund another purchase. For example, a company might own an office with substantial equity and want to purchase a second office or warehouse. Instead of selling the first property, the company could investigate whether additional borrowing can be raised against it. This can potentially provide part of the capital required for another purchase. However, the overall borrowing position needs to be considered. A lender may assess both the existing property and the proposed acquisition, together with the company's financial position. If purchasing another property is the main objective, you may also want to review your commercial mortgage options before deciding whether refinancing the existing property is the right structure.  7. Your Existing Mortgage No Longer Fits Your Business Your circumstances may be very different from when you first arranged the mortgage. Perhaps the business has changed direction. Maybe the property is now being used differently, additional tenants have moved in or the company has expanded. Your existing lender's product may no longer fit the way you use the property or the way you want to structure your borrowing. A commercial remortgage gives you an opportunity to review the entire arrangement. This does not necessarily mean changing lender is the right solution. Your current lender may have a suitable refinancing option. The important step is reviewing the alternatives before committing to a new arrangement. 8. Your Existing Mortgage Term Is Too Long or Too Short The mortgage term can affect monthly repayments and the total amount of interest paid over time. If business circumstances have changed, you may want to investigate whether a different term is appropriate. For example, a business with stronger cash flow might consider whether it can comfortably support higher monthly repayments in exchange for reducing the repayment period. Alternatively, a business focused on preserving cash flow may need to investigate whether a longer term is available and suitable. The lender will assess the proposed term alongside affordability and other criteria. 9. You Need More Predictable Business Cash Flow Commercial property finance can have a significant effect on monthly business expenditure. If your current mortgage structure creates uncertainty around repayments or does not fit your cash flow planning, refinancing may be worth reviewing. A fixed rate can provide greater payment predictability during the fixed period, while variable arrangements may move with the lender's relevant pricing. There is no universally suitable structure. The right choice depends on your business's cash flow, risk tolerance, future plans and the terms available from lenders. 10. You Are Approaching the End of an Interest Only Period Some commercial mortgages are structured on an interest only basis for an agreed period. If that period is coming to an end, it is important to review the position well in advance. You may need to consider: Refinancing Repaying some of the capital Selling the property Changing the repayment structure Moving to another suitable finance arrangement Do not assume that an interest only arrangement will simply continue on the same terms. Start reviewing your options early so there is time to deal with valuation, underwriting and legal requirements. 11. Your Property Is Now Producing More Rental Income For commercial investment property, rental income can be an important part of the refinancing assessment. If the property has gained new tenants, increased rental income or stronger lease arrangements since the original mortgage was taken out, it may be worth reviewing the existing finance. For example, an investment company may have purchased a £1.2 million office building with several vacant units. After completing improvements, the company could have a higher occupancy rate and stronger rental income. The property and financial position may therefore look different from when the original mortgage was arranged. That does not guarantee better refinancing terms, but it can justify reviewing the available options. 12. You Want to Change Lenders You do not have to remain with the lender that originally financed your property. A commercial remortgage can involve moving to another lender if the new lender's criteria and terms are more suitable. Different commercial lenders can have different approaches to: Property types Loan to value Business experience Rental income Company structures Credit history Loan sizes Repayment terms Property use This is particularly relevant for more complex cases. The lender that was suitable when you first purchased the property may not necessarily be the lender that best fits your current circumstances. How Early Should You Start Planning a Commercial Remortgage? There is no single timetable that applies to every commercial property. However, it is sensible to start reviewing the situation several months before your current deal ends. Residential mortgage providers commonly recommend starting several months before expiry, and commercial refinancing can require additional time because of property valuations, business underwriting and legal work. NatWest's current residential guidance suggests three to six months for many remortgage situations, while commercial transactions are assessed according to the individual circumstances.  For a commercial property, starting early gives you time to: Check your existing mortgage terms Identify any early repayment charges Estimate the property's current value Review business performance Determine how much you need to borrow Decide whether you want to raise additional capital Compare suitable lenders Prepare financial documents Arrange a valuation Complete the legal work If your mortgage is due to expire soon, it is better to begin the conversation now rather than assume refinancing can be completed immediately. Should You Remortgage Before Your Current Deal Ends? Possibly, but this depends on the numbers. If you leave a fixed rate early, your existing lender may charge an early repayment charge or another exit cost. Your mortgage documents should be checked carefully before deciding to refinance. Early repayment charges are designed to compensate lenders when a borrower repays or changes a mortgage during a period where the lender expected the borrowing to remain in place. HSBC's published mortgage guidance provides an example of how such charges can apply to fixed rate borrowing. Commercial mortgage terms vary by lender and product, so the actual charge needs to be confirmed with your existing lender. (HSBC UK) The key question is: Will the financial and strategic benefit of refinancing outweigh the cost of leaving the existing arrangement? When Might You Not Want to Remortgage a Commercial Property? Remortgaging is not automatically beneficial. There are circumstances where keeping the existing mortgage could make more sense. The Early Repayment Charge Is Too High If you are still within a fixed rate period and the exit charge is substantial, switching early may not produce enough savings to justify the cost. Your New Rate Is Not Significantly Better A lower rate may look attractive, but the overall cost of refinancing could eliminate the expected saving. Your Business Financials Have Deteriorated A new lender will assess your current circumstances. If business performance has weakened significantly, refinancing may be more difficult or the available terms may be less attractive. NatWest notes that lenders assess affordability and credit information when considering business borrowing.  Your Property Value Has Fallen A reduction in property value can increase your LTV. That can affect the amount you may be able to borrow and the terms available. You Are Planning to Sell Soon If you expect to sell the commercial property relatively soon, the cost and effort involved in refinancing may not be justified. The decision should be based on the expected holding period and total refinancing costs. What Costs Should You Consider Before Remortgaging? Before making a decision, calculate the full cost of the proposed transaction. Potential costs can include: Early Repayment Charges Your existing lender may charge an early repayment fee if you leave before the agreed date. Arrangement Fees The new lender may charge an arrangement or facility fee. Valuation Costs The new lender may require a commercial valuation. Legal Fees Solicitors may be required to deal with the existing lender's charge and establish the new lender's security. Broker Fees A broker may charge a fee for arranging or advising on the finance. Other Costs Depending on the transaction, there may be additional administrative or property related costs. The important point is to calculate the total cost of refinancing, not simply the difference between two interest rates. A Simple Commercial Remortgage Break Even Example Imagine your existing commercial mortgage is: Balance: £600,000 Current annual interest cost: £36,000 Potential new annual interest cost: £30,000 Potential annual saving: £6,000 Now assume the total refinancing costs are £18,000. The simple break even period would be: £18,000 ÷ £6,000 = 3 years If you expect to retain the new mortgage for considerably longer than three years, the potential savings may become more meaningful. If you expect to sell or refinance again within a short period, the calculation may look very different. This is only an illustration and does not account for future rate changes, tax, capital repayments or changes in property value. What Will a Lender Look at When You Remortgage? A commercial lender can assess several areas of the application. The Property The lender may consider: Location Property type Condition Market value Use Rental income Lease arrangements Occupancy The Business For owner occupied property, the lender may assess: Turnover Profitability Accounts Bank statements Existing debts Cash flow Business history Future plans The Borrower The lender may also consider the company's ownership structure and the directors involved. Depending on the transaction, personal guarantees may be required. The Proposed Loan The lender will look at: Loan amount LTV Term Repayment structure Interest rate Purpose of borrowing The exact criteria differ between lenders. What Documents Should You Prepare? Preparing documents before approaching lenders can help reduce avoidable delays. You may need: Latest company accounts Management accounts Business bank statements Existing mortgage statement Redemption statement Property details Lease agreements Rental statements Details of existing borrowing Company structure information Director information Business forecasts Details of how additional borrowing will be used If you are releasing equity, explain clearly what the funds will be used for. A clear purpose can help the lender understand the proposed transaction. What If You Want to Remortgage a Commercial Property to Release Capital? This is one of the most common strategic reasons for reviewing commercial property finance. Imagine a company owns a warehouse worth £900,000 and has a £400,000 mortgage outstanding. The business wants £100,000 to invest in new machinery. Rather than selling the warehouse, it could investigate whether a new mortgage of £500,000 is achievable. If approved, the existing £400,000 borrowing would be repaid and the additional £100,000 could potentially be released. The lender would still need to assess affordability, LTV and the purpose of the funds. If the objective is business expansion, it may also be worth reviewing business mortgage options alongside a commercial remortgage.  What If Your Commercial Property Is Owned by a Limited Company? A limited company can potentially remortgage a commercial property that it owns. The lender may consider the company accounts, directors, property value, existing borrowing, rental income and the purpose of the new loan. For an owner occupied property, the trading performance of the company may be particularly relevant. For an investment property, rental income and lease arrangements can play an important role. The correct structure depends on the circumstances and lender criteria. What If You Have a Semi Commercial Property? Semi commercial properties combine residential and commercial elements. For example, a property might contain a shop on the ground floor with flats above. These properties can require specialist assessment because the lender needs to consider both elements of the property and the associated income. The Commercial Mortgage Guy offers semi commercial finance for mixed use properties and notes that these cases can require specialist commercial property lending. If you own a semi commercial property, do not automatically assume that a standard commercial remortgage will be the appropriate product. Can You Remortgage After Making Improvements to the Property? Potentially. Property improvements can affect value, rental income and the overall commercial proposition. For example, a company may have renovated an office building, improved its energy efficiency or converted unused space into lettable accommodation. If the property value or income has changed materially, it may be worth reviewing the existing mortgage. However, a new lender will still conduct its own assessment. The amount spent on improvements does not automatically equal the amount added to the property's market value. What If Your Business Has Grown Since the Original Mortgage? Business growth can strengthen a refinancing application, but lenders will assess the evidence rather than relying on projected growth alone. Prepare: Recent accounts Management information Bank statements Evidence of consistent revenue Details of existing debts Future business plans A lender will want to understand whether the proposed borrowing is sustainable. How Long Does Commercial Remortgaging Take? The timeline varies considerably. A straightforward transaction may progress relatively quickly, while more complex cases can take longer because of valuation, underwriting, legal work or unusual property circumstances. If timing is important, you should plan ahead. This is particularly relevant if your existing mortgage has a fixed rate expiry or if you have a deadline for releasing capital. If you are planning around a mortgage expiry date, you can also read our guide on how long a commercial mortgage takes to complete for additional guidance. How Can You Tell if It Is the Right Time? Before deciding, ask yourself five questions: 1. When does my current deal end? Knowing the exact date is essential. 2. What will it cost to leave my current mortgage? Check early repayment charges and other exit costs. 3. What is my property worth today? A change in value can alter your LTV. 4. How much do I actually need to borrow? Do not automatically increase borrowing simply because equity is available. 5. What do I want the new mortgage to achieve? A clear objective makes it easier to compare options. If the answers indicate that the current arrangement no longer fits your circumstances, it may be time to investigate refinancing. Frequently Asked Questions When is the best time to remortgage a commercial property? There is no single best time for every borrower. Common triggers include the end of an existing deal, a significant change in property value, the need to release equity or a change in business financing requirements. How many months before my commercial mortgage ends should I start? It is sensible to start reviewing your position several months before the existing deal ends. Commercial transactions can involve valuation, underwriting and legal work, so leaving the process until the final weeks can create unnecessary pressure. Can I remortgage a commercial property before the fixed rate ends? Potentially, but your existing mortgage may include an early repayment charge. You should compare the expected benefits of refinancing with the cost of exiting the current arrangement. Can I remortgage to release equity? Potentially. A lender may allow additional borrowing against available equity, subject to its LTV, affordability and other criteria. Can I remortgage if my commercial property has increased in value? Yes, an increase in property value can be relevant when reviewing your LTV and refinancing options. A lender will normally make its own assessment of the property's current value. Can a limited company remortgage commercial property? Yes, a limited company can potentially refinance a commercial property it owns, subject to lender criteria and assessment of the company and property. Is remortgaging cheaper than staying with my existing lender? Not necessarily. You need to compare the total cost of each option, including interest, fees and any early repayment charges. Can I remortgage a commercial investment property? Potentially. Investment property refinancing can involve assessment of rental income, tenants, lease terms, property value and the borrowing structure. Can I use a commercial remortgage to fund business expansion? Potentially. Commercial remortgaging can sometimes be used to raise additional finance for an approved business purpose. Should I speak to a commercial mortgage broker before remortgaging? A broker may be useful if you want to compare lender criteria or your case involves unusual property, company or borrowing circumstances. The Commercial Mortgage Guy states that it works across a wide panel of UK lenders, including specialist and niche providers.  Final Thoughts Knowing when to remortgage a commercial property is about more than watching interest rates. The decision can become relevant when your current mortgage deal is approaching its end, your property's value has changed, your business has grown, you want to release equity or your existing finance no longer fits your plans. Before proceeding, calculate the total cost of refinancing and compare it with the potential benefit. Check early repayment charges, review your current mortgage, establish your property's likely value and understand how much additional borrowing you actually need. It is also worth starting the process early. Commercial refinancing can involve lender underwriting, valuation and legal work, so giving yourself sufficient time can make the process easier to manage.
