Buying commercial property can be a major step for any business. Whether you are purchasing offices, a retail unit, a warehouse, industrial premises, hospitality space or a mixed-use property, one of the first questions is usually how much deposit will be needed. Unlike some residential mortgages, commercial mortgage deposits can vary widely depending on the property, business, lender and overall risk profile.
Understanding deposit requirements early can help your business plan more effectively. A deposit affects how much you need to contribute upfront, how much you need to borrow, and how lenders assess the overall application. For many businesses, preparing the deposit is one of the most important parts of getting ready for a commercial property purchase.
Commercial Mortgages UK helps businesses explore commercial mortgage and loan options, including finance for buying commercial property, raising money against existing premises and reviewing specialist lending routes. The right deposit level will depend on your individual circumstances, so it is important to seek advice before making a commitment.
What Is a Commercial Mortgage Deposit?
A commercial mortgage deposit is the amount of money a business or borrower contributes towards the purchase of a commercial property. The remaining balance is usually funded through a commercial mortgage, which is secured against the property being purchased.
For example, if a business is buying a property for £500,000 and the lender agrees to provide 70% loan-to-value, the mortgage would be £350,000 and the business would need to contribute £150,000 as a deposit, before allowing for fees, taxes and other costs.
The deposit helps reduce the lender’s risk. A larger deposit usually means the business is borrowing a smaller percentage of the property value, which may improve the strength of the application and potentially widen the range of lenders willing to consider it.
How Much Deposit Could You Need?
Commercial mortgage deposits are not fixed in the same way for every borrower. As a general guide, many businesses may need to contribute around 25% to 40% of the property value, although this can vary depending on the lender, the type of property, the business strength and the purpose of the purchase.
Some stronger applications may be considered at higher loan-to-value levels, while more complex cases may require a larger deposit. A lender may ask for a higher contribution if the business has limited trading history, the property is specialist, income is inconsistent or the application presents more risk.
This is why it is important to avoid assuming that one deposit percentage will apply to every commercial mortgage. The amount required should be assessed as part of the wider application.
Loan-to-Value Explained
Loan-to-value, often shortened to LTV, is the percentage of the property value that the lender is prepared to lend. If a lender offers a 75% loan-to-value commercial mortgage, the borrower would usually need to provide the remaining 25% as a deposit.
For example, on a £400,000 commercial property, a 75% LTV mortgage would mean borrowing £300,000 and contributing a £100,000 deposit. If the lender only offered 60% LTV, the mortgage would be £240,000 and the deposit would need to be £160,000.
Loan-to-value is one of the key factors in commercial mortgage planning because it directly affects the upfront deposit requirement and the ongoing borrowing amount.
Why Deposit Requirements Vary
Commercial mortgage deposit requirements vary because every case is assessed individually. Lenders look at the borrower, the property, the purpose of the loan and the repayment plan before deciding how much they are willing to lend.
A long-established business with strong accounts, stable profits and a straightforward owner-occupied property may be viewed differently from a new business purchasing specialist premises. Similarly, a commercial investment property with strong tenant income may be assessed differently from a vacant building that needs refurbishment.
The deposit helps balance this risk. Where a lender sees more uncertainty, a larger deposit may be required to reduce the loan-to-value.
Owner-Occupied Commercial Properties
An owner-occupied commercial mortgage is used when a business buys premises for its own use. This could include a company buying an office, workshop, warehouse, shop, surgery, salon, garage or hospitality venue from which it will trade.
For this type of mortgage, lenders usually assess the strength of the business and its ability to afford the repayments. They may review accounts, bank statements, trading history, profit levels, cash flow and future plans.
If the business is well established and the property is suitable for its operations, the deposit requirement may be more favourable than a higher-risk case. However, the lender still needs to be confident that repayments are affordable and that the property provides suitable security.
Commercial Investment Properties
A commercial investment mortgage is usually used when the borrower buys a property to let to another business. In this case, the lender will look closely at the rental income, lease terms, tenant strength, property type and wider investment plan.
The deposit requirement may depend on how reliable the rental income appears to be. A property let to a strong tenant on a long lease may be more attractive to lenders than a property with short leases, void periods or uncertain demand.
Commercial investment properties can be more complex than owner-occupied purchases, so it is important to understand the lender’s criteria before relying on a particular deposit figure.
Start-Up Businesses May Need Larger Deposits
Start-up businesses can face more challenges when applying for commercial property finance because they may not have several years of trading accounts. Without an established track record, lenders may view the application as higher risk.
This does not always mean finance is impossible, but it may mean the business needs a stronger deposit, a detailed business plan, relevant experience and clear evidence of affordability. The lender will want to understand how the business intends to generate income and maintain repayments.

The Property Type Can Affect the Deposit
The type of commercial property being purchased can have a significant impact on the deposit required. Standard offices, shops, warehouses and industrial units may be easier for lenders to assess than highly specialist properties.
Specialist properties such as hotels, care homes, pubs, restaurants, leisure venues, petrol stations or properties with unusual planning use may require more detailed assessment. Some lenders may be cautious with properties that could be harder to sell or re-let if the borrower failed to maintain repayments.
Where a property is considered more specialist or higher risk, a lender may reduce the loan-to-value and ask for a larger deposit.
Property Condition and Valuation
Lenders will usually require a valuation before agreeing a commercial mortgage. The valuation helps confirm whether the property is suitable security for the loan and whether the purchase price appears reasonable.
If the property is in good condition and ready for use, the application may be more straightforward. If the property needs major repairs, refurbishment or change of use, the lender may be more cautious. This could affect how much they are willing to lend and how much deposit is required.
Where a property needs improvement works, borrowers should also budget for the cost of refurbishment alongside the deposit and purchase costs.
Other Costs to Budget For
The deposit is only one part of the upfront cost of buying a commercial property. Businesses should also plan for legal fees, valuation fees, lender arrangement fees, broker fees where applicable, survey costs, insurance and any tax due on the purchase.
If the property needs work before it can be used, fit-out costs, refurbishment costs, compliance upgrades and moving costs should also be considered. Underestimating these additional costs can put pressure on cash flow after completion.
A sensible budget should include the deposit plus all expected transaction and setup costs. This gives the business a clearer picture of how much cash will be needed before, during and after the purchase.
Can You Raise a Deposit from Existing Commercial Property?
Some businesses already own commercial property and want to use available equity to help fund another purchase. In some cases, it may be possible to raise finance against an existing property and use the released funds towards a deposit or wider business plans.
This may suit businesses looking to expand, buy another site, refurbish premises or restructure existing borrowing. However, using property as security is a major decision and must be considered carefully.

Could a Second-Charge Commercial Loan Help?
In some situations, a business may already have a commercial mortgage but need additional funding. If it does not make financial sense to replace the existing facility, a second-charge commercial loan may be considered.
This type of borrowing sits behind the existing first charge and is secured against the property. It may be used for deposits, growth, refurbishment, equipment or other business purposes, subject to lender criteria and affordability.
Second-charge finance is not suitable for every business, but it may be worth exploring where there is enough equity and a clear repayment plan. For more detail, see When Could a Second-Charge Commercial Loan Be the Right Option?.
How Business Strength Affects Deposit Requirements
Lenders will usually look closely at the strength of the business behind the application. They may consider turnover, profitability, cash flow, trading history, sector, management experience and existing borrowing.
A business with strong accounts and reliable income may have access to a wider choice of lenders than one with irregular revenue or recent financial difficulties. Where lenders feel confident about affordability, they may be more comfortable offering a higher loan-to-value.
Businesses with weaker accounts or complex circumstances may still have options, but they may need a larger deposit or a more specialist lending approach.
Credit History and Borrower Profile
Credit history can also influence the deposit required. Lenders may review the business credit profile, director credit history, existing commitments, missed payments, County Court Judgments and other financial information.
A clean and well-managed credit profile can support an application, while adverse credit may lead to stricter criteria or a larger deposit requirement. Some specialist lenders may still consider more complex cases, but the terms may differ from standard commercial mortgage products.
If your circumstances are complex, professional advice can help identify lenders that may be more suitable for your situation.
Deposit Planning for Green Business Projects
Some businesses are purchasing or improving premises with sustainability in mind. This may include energy-efficient upgrades, greener buildings, renewable technology, improved insulation or environmentally focused projects.
Deposit requirements will still depend on lender criteria, property value and affordability, but the purpose of the project may influence which lenders or funding routes are worth considering.

Why a Bigger Deposit Can Help
Providing a larger deposit can sometimes strengthen a commercial mortgage application. It reduces the amount being borrowed, lowers the loan-to-value and may reduce the lender’s risk.
A lower loan-to-value may also give the business more breathing space if property values change or trading conditions become more difficult. It can also reduce monthly repayments because the mortgage balance is smaller.
However, using too much cash as a deposit can also create problems if it leaves the business short of working capital. The deposit should be balanced against the need to keep enough money available for trading, maintenance, staff, stock, tax, equipment and unexpected costs.
Preparing Before You Apply
Before applying for a commercial mortgage, it is useful to prepare key information. This may include business accounts, bank statements, tax information, details of existing borrowing, property information, business plans, leases where applicable and evidence of the deposit source.
Lenders may want to understand where the deposit is coming from. This could be retained profits, savings, director funds, proceeds from a sale, refinancing or another acceptable source. Clear records can help the application process run more smoothly.
Good preparation also allows your adviser to identify potential issues early and approach lenders that are more likely to consider the case.
Why Professional Advice Matters
Commercial mortgage deposits can vary widely, so it is important to get advice before assuming how much your business will need. The deposit is only one part of the decision, alongside affordability, lender criteria, property type, fees, repayment structure and long-term plans.
Professional advice can help you compare options, understand realistic loan-to-value levels and prepare the application properly. This is especially valuable if the property is unusual, the business is new, the borrowing amount is large or the deposit is being raised from another asset.
Commercial Mortgages UK can help businesses review available routes and understand what lenders may require before moving forward.
