The short answer: most UK lenders expect a 25%–40% deposit for a commercial mortgage, but the number moves up or down depending on the property’s saleability, the strength of the income, and the borrower’s track record. In this guide to the commercial mortgage deposit uk landscape, we’ll break down realistic deposit ranges by property type and deal profile, and show how better security can change the conversation. If you want the bigger picture on how these loans work, read our complete guide to commercial mortgages.
Rule of thumb: the more “mainstream” the property and the more reliable the income, the higher the loan-to-value (LTV) a lender is usually willing to offer.
Typical deposit ranges for UK commercial mortgages (at a glance)
While every lender’s criteria differs, these ranges reflect common expectations for standard commercial mortgage deals in the UK.
- Low-risk / prime deals: 20%–30% deposit (70%–80% LTV)
- Most mainstream deals: 25%–40% deposit (60%–75% LTV)
- Higher-risk / specialist property or weaker profile: 35%–50%+ deposit (50%–65% LTV)
What lenders are really pricing when they set the deposit
A “deposit” in commercial lending is less about a fixed rule and more about risk appetite. The deposit (and overall LTV) is the lender’s buffer if they ever need to sell the asset to recover the loan.
Key factors that influence how much deposit you’ll need include:
- Property marketability: how easy it would be to sell quickly (location, demand, condition).
- Income strength: rent quality for investments, or trading strength for owner-occupied premises.
- Lease profile: lease length, break clauses, rent review pattern, and tenant covenant.
- Valuation approach: vacant possession value vs investment value can change the numbers materially.
- Borrower strength: experience, credit profile, and available cash reserves.
- Debt service coverage: whether the property income or business cash flow comfortably covers repayments.
Deposit expectations by property type
Owner-occupied premises (offices, industrial units, warehouses)
For trading businesses buying their own premises, deposits often sit around 25%–35%, especially where accounts are strong and the property is in a liquid market. Some prime, straightforward deals can move closer to 20%–25% if the lender is confident on affordability and exit.
Commercial investment property (buy-to-let)
Investment deals typically require a 25%–40% deposit. Stronger tenant covenants, longer leases, and stable sectors can support higher LTVs (lower deposits). Short leases, niche locations, or reliance on a single tenant usually push deposits up.
Retail, leisure, and hospitality (shops, restaurants, pubs, hotels)
Because these assets can be more sensitive to footfall, consumer spending, and operator performance, deposits often land in the 30%–45% range. Where the repayment plan depends heavily on trading, lenders may stress-test more aggressively and expect a bigger equity contribution.
Specialist property (care, medical, education, petrol stations, unusual assets)
Specialist properties often need 35%–50%+ deposits, particularly where there’s limited demand if the current use fails or where alternative use is restricted. In practice, lenders want a wider safety margin if resale could be slower or valuation is more complex.
Mixed-use / semi-commercial (e.g., shop with flat above)
Mixed-use properties can fall anywhere from 25%–40% deposit depending on the split between residential and commercial space, the condition, and how the income is structured. Lenders will also look closely at who occupies each part and the tenancy details.
How stronger security can reduce the deposit (or improve the terms)
If a deal is borderline on LTV, lenders may still proceed if you can strengthen the overall security package. That doesn’t always mean a smaller cash deposit, but it can lead to better leverage, pricing, or flexibility.
Common ways borrowers strengthen a commercial mortgage proposal include:
- Additional property security: offering another asset as extra collateral (cross-collateralisation).
- Lower overall gearing: keeping more cash back in the business as contingency can reassure lenders.
- Demonstrable liquidity: showing you can cover voids, repairs, or rate shocks without distress.
- Cleaner structure: simple ownership and clear source-of-funds evidence reduce underwriting friction.
If you’re weighing options, our commercial mortgage finance page outlines how different structures and security profiles can affect what lenders will consider.
Deal profile factors that push deposits up (and how to counter them)
Two borrowers can buy the same building and be offered different LTVs. The difference is often the “deal profile” around the asset.
- Short trading history: newer businesses often need more deposit or stronger supporting evidence (contracts, pipeline, retained profits).
- High borrower concentration: reliance on one client or one revenue stream can increase perceived risk.
- Weak credit events: not always a deal-breaker, but it can increase deposit expectations.
- Vacant or under-let property: lenders may treat it as higher risk unless there’s a clear, evidenced letting plan.
- Non-standard construction or condition issues: can reduce lender appetite until remedied.
Beyond the deposit: the total cash you may need
The deposit is only one line in the budget. UK commercial purchases commonly require additional funds for fees and taxes, and lenders expect you to evidence you can meet them.
Depending on the transaction, you may need to allow for:
- Valuation fees and (sometimes) specialist reports
- Legal fees (your solicitor and the lender’s solicitor, if payable by you)
- Arrangement fees and broker fees (where applicable)
- Refurbishment / compliance works (fire safety, EPC improvements, access)
- Stamp Duty Land Tax where payable (see HMRC SDLT rates for non-residential and mixed property)
- Potential VAT treatment on property transactions (see HMRC guidance on VAT on land and property)
Worked examples: what deposit could look like in practice
Example 1: Owner-occupied industrial unit with solid accounts
A trading business buys a £800,000 warehouse in a strong industrial area. With robust affordability and good credit, a lender offers 70% LTV.
- Loan: £560,000
- Deposit: £240,000 (30%)
Example 2: Investment property with strong tenant and long lease
An investor buys a £1,200,000 office building let to a strong covenant on a long lease. The lender is comfortable at 75% LTV due to income reliability.
- Loan: £900,000
- Deposit: £300,000 (25%)
Example 3: Hospitality property where repayments rely on trading
An operator purchases a £650,000 restaurant premises where the business cash flow is key to affordability. The lender takes a cautious view and offers 60% LTV.
- Loan: £390,000
- Deposit: £260,000 (40%)
How to position your application for a lower deposit
Even when the property type is fixed, you can often improve the offer by presenting the deal in the way UK commercial lenders expect. Strong packaging reduces uncertainty, which can support a higher LTV in the right circumstances.
- Prepare lender-ready financials: up-to-date accounts, management figures, and sensible forecasts.
- Evidence the source of deposit: savings, retained profits, sale proceeds, or verified gift/investment routes.
- Be clear on the property story: why this property, why this location, and how it supports the business plan.
- Document leases properly (for investments): full AST/lease pack, rent schedule, and proof of rent received.

FAQs
What’s the minimum deposit for a commercial mortgage in the UK?
On the most straightforward, low-risk deals, you may see deposits around 20%–25%. For many borrowers and property types, 25%–40% is a more typical expectation.
Is the deposit based on the purchase price or the valuation?
Usually it’s based on the lender’s valuation figure. If you agree a purchase price above the valuation, you may need to fund the difference on top of the “deposit”.
Can I use another property instead of putting in a big cash deposit?
Sometimes. If you can offer additional security (for example, another property with available equity), some lenders may consider higher overall leverage. This depends heavily on risk, location, and your wider profile.
Do I need a bigger deposit if I’m a new business?
Often, yes. Limited trading history can mean the lender wants more equity in the deal, unless you can offset it with strong experience, a proven sector track record, or robust contracted income.
What happens if the property is vacant?
Vacant properties can attract lower LTVs because there’s no income to support repayments and resale risk can be higher. A strong letting plan (or pre-lets) can help.
Can I borrow the deposit?
It’s possible in some structures (for example, raising funds against another asset), but lenders will still look at your overall leverage and affordability. If the deposit is funded by short-term debt, expect additional scrutiny.
