Commercial property loan interest rates in the UK have entered a new phase as of late 2025, driven by changes in the Bank of England base rate, evolving economic conditions, and lenders’ appetite for business risk. Securing a great deal for a commercial mortgage can make the difference between business growth and missed opportunity. This in-depth guide explores the 2025 commercial financing landscape, from average rates to the application process, market outlook, and practical tips for business owners, investors, and property developers.

Understanding Commercial Property Loans

A commercial property loan (commercial mortgage) is a form of secured lending used to purchase, refinance or develop property intended for business purposes or for investment yields. Unlike residential mortgages, these loans are individually structured, subject to bespoke underwriting, and influenced heavily by the property’s intended use, lease profile, and the applicant’s business credentials.

Common Uses for Commercial Property Loans

Purchasing a business’s own office, shop, or warehouse premises
Buying investment properties like retail parks, industrial units, or mixed-use developments
Refinancing existing commercial property loans for improved rates or new terms
Funding property development projects
Acquiring property portfolios for business expansion or rental income

How Commercial Mortgage Rates Work

Interest rates on UK commercial property loans aren’t as simple as residential mortgage rates. They are determined by a mix of market factors and the unique details of each loan application. Lenders assess risk, property type, income potential, and broader economic conditions before quoting a rate.

Key Influences on Commercial Mortgage Rates

Bank of England base rate: The foundation for all UK lending rates. Recent base rates in 2025 hover between 4.00% and 4.5%, after reaching a high of 5.25% in 2024.
Loan-to-Value (LTV): The percentage of the purchase price being borrowed. Higher LTV (e.g. 80% of the property price) typically commands higher rates, as the lender’s risk grows.
Business health: Lenders scrutinise business accounts, trading history, cash flow, and personal and business credit scores.
Property type and use: Owner-occupied (businesses buying premises for their own use) often attracts lower rates than properties bought purely for investment or letting.
Tenant and lease profile: For investment property, good tenants with secure, long leases mean lower perceived risk and sometimes lower rates.
Fixed vs. Variable Rates: Fixed rates give predictable repayment costs but may be more expensive up front. Variable rates track the BoE and can change over time.

Typical Commercial Mortgage Interest Rates in 2025

As of autumn 2025, commercial property loan rates in the UK typically fall within three broad ranges:

Lowest risk, prime properties: 3.5% to 5% (usually reserved for strong applicants, solid businesses, prime locations, and low LTV)
Owner-occupied properties (majority): 5.5% to 7.2%
Commercial investment properties or complex cases: 7% to 12%

Fixed rates for investment purchases are usually at the higher end, especially for 5-year fixes or longer. Variable rates, meanwhile, fluctuate depending on the Bank of England’s policy decisions, but they currently track in the lower part of these bands.

Deposit and LTV: What You Need

Commercial mortgages normally require bigger deposits than residential loans due to greater risk and property volatility. Typical deposit requirements for 2025 are:

Owner-occupied premises: Minimum 20–25% deposit (75–80% LTV available from lenders)
Investment or complex properties: 25–40% deposit, with high LTVs reserved for especially strong applicants and prime property
First-time buyers or businesses in high-risk sectors may face even higher deposit requirements or stricter eligibility checks.

The Application and Approval Process

Obtaining a commercial property loan is more involved than applying for a residential mortgage. You should expect a thorough review of financial documentation, property valuations, and potentially in-person interviews.

Core Steps in the Process

Initial enquiry: Lender or broker collects initial information and gives an idea of likely rates and borrowing terms.
Documentation: Submission of detailed business accounts (2–3 years), business plans, director’s income proofs, and tenancy information if applicable.
Credit checks and property assessment: Both personal and business credit histories are reviewed. The property is professionally valued and stress-tested as security.
Offer and negotiation: Lender issues a formal offer, subject to final checks. There may be scope for negotiation, especially with brokers involved.
Legal and completion: Both sides instruct solicitors, handle legal due diligence, and sign formal loan agreements.
Drawdown and repayments: Funds are released, repayments begin according to the chosen schedule and type (fixed or variable, capital & interest or interest-only).

Commercial Mortgage Fee Structure

Interest rates are only part of the cost for commercial property finance. Businesses should also budget for various fees:

Arrangement/setup fees: Typically 1–2% of the total loan, charged upfront or added to the balance.
Valuation fees: Paid for a full professional property valuation, costs escalate with property value.
Legal fees: Both the borrower and the lender’s legal fees are payable by the applicant.
Broker fees: If a broker is used, their fee is often 1% of the loan amount, but some specialist brokers work with smaller or no fee for larger deals.
Early Repayment Charges: Particularly for fixed rate loans, these can be substantial if the loan is repaid before the end of the fixed period.

Factoring all these into overall loan cost is essential for accurate comparison and budgeting.

Types of Commercial Property Loans Explained

Owner-Occupied Commercial Mortgages

Used by businesses wanting to purchase premises for direct use (e.g. a bakery buying its shop or a logistics firm buying a depot). Lending decisions rest heavily on business health, profitability, LTV, and property type. Rates are, on average, lower than for investment.

Terms typically range from 5 to 25 years.
Up to 80% LTV possible, though lower deposits receive better terms.
Some lenders offer “green” discounts for energy-efficient property (EPC rating A–C).

Commercial Investment Mortgages

These loans help landlords or property companies acquire properties with the aim of letting them to other businesses for rental income. The primary risk assessment is based on the quality of leases, tenants, yield, location, and overall investment risk.

Fixed rates (for 5–10 years) often priced between 7% and 8.9% at 75% LTV.
Interest-only terms may be available (usually up to 35 years), suitable for landlords managing yield and cash flow.
Lease agreements, tenant profiles, and full property valuation are required.

Semi-Commercial and Mixed-Use Loans

These cover properties that mix commercial and residential elements, like flats above retail shops. Specialist lenders operate here, as the assessment must account for multi-use risk and potential for conversion or regulation change.

Variable or Fixed Rate: Which Is Better?

Variable rates are tied to the Bank of England’s base rate. In falling rate environments, they can save money, but repayments also rise if the base rate strengthens.
Fixed rates lock in the cost for a set period (3, 5, or 10 years), with predictability at the cost of potentially higher upfront interest.

Variable or fixed boils down to risk tolerance, forecasts for the economic climate, and the business’s need for repayment certainty.

2025–2026 Market Trends and Forecast

Throughout 2025, commercial mortgage rates were influenced by steady but cautious reductions by the Bank of England. Although the base rate dropped from peak 2024 highs, lenders have not fully passed on savings due to lingering economic uncertainty and demand for prudent risk management.

Borrowing costs have fallen from 2024 highs, but remain elevated compared to the low-rate era of the 2010s or early 2020s.
Lenders forecast modest further rate cuts heading into 2026, dependent on inflation stability and economic performance.
Demand for commercial property loans grew nearly 10% year-on-year as businesses and investors sought to lock in rates before potential future increases.
Sustainability and “green” financing are picking up pace. Lenders and valuers look favourably on high EPC rated properties, sometimes incentivising upgrades with preferential rates.
Broker and product diversity is increasing, meaning businesses have broader options but also need to compare more closely.

Tips for Securing the Best Commercial Mortgage Deal

Prepare up-to-date and accurate financial statements, and ensure strong trading history.
If the business or property is energy-efficient (EPC A–C), emphasise this for possible rate discounts.
Lower the loan-to-value ratio where possible. The more capital you can put up front, the better the rate.
Shop around and compare multiple lenders, including challenger banks and specialist providers.
Consider using a reputable brokerage for access to exclusive or specialised deals, but always clarify fees.
Forecast cash flow under different interest rate scenarios, especially if considering a variable rate product.
Negotiate on arrangement fees where possible; larger, established borrowers sometimes have more leverage.

Risks and Market Considerations

Commercial property investment, while potentially lucrative, is not without risk. Market shocks, tenant defaults, and economic downturns can all affect property values and rental income, making it vital to stress-test projections and avoid overexposure.

Variable rates can increase monthly repayments sharply if the base rate rises unexpectedly.
Refinancing may become less attractive or possible if property values fall or if banks tighten lending standards.
Unexpected property costs (maintenance, voids) can strain cash flow, particularly on interest-only terms.

Prudent financial planning, monitoring economic signals, and regular review of loan products will help businesses manage these risks.

Regulatory and Tax Considerations

Interest paid on commercial property loans is generally tax-deductible as a business expense, subject to current rules.
Buying in a company name (as opposed to personally) may offer certain advantages for higher rate taxpayers or those building a property portfolio.
Stamp Duty Land Tax, VAT rules, and capital gains tax implications vary for commercial property—always seek professional advice.

Frequently Asked Questions (FAQ)

What is a commercial mortgage versus a business loan?

A commercial mortgage is specifically for property purchase, using the premises as security, and usually offers better rates and higher borrowing limits than unsecured business loans. Business loans are more versatile but do not necessarily provide the sums required for property investment or as long a repayment term.

How much can I borrow for a commercial property loan?

Borrowing amounts range from £50,000 up to £35 million or even higher for portfolio or complex deals. Actual maximums depend on business health, the property’s value, projected income, and lender risk appetite.

Do I need a deposit for a commercial property loan?

Yes, most lenders require at least a 25% deposit (75% LTV), although lower deposits may be accepted for exceptionally strong businesses or prime properties.

Are commercial property loan rates negotiable?

Yes. While base rates are set by economic conditions, headline rates can sometimes be improved by negotiation, especially through brokers, larger loan sizes, or by presenting a particularly strong application.

Is it easier to get a commercial mortgage as an established business?

Absolutely. Lenders favour businesses with strong credit history, 2–3 years of profitable accounts, and existing property or borrowing track records. Start-ups can still qualify, but may face lower limits, higher rates, or need to provide personal guarantees.

Can I get an interest-only commercial property loan?

Many lenders offer interest-only options—especially for investment properties. These can last for the full term, or convert to repayment after an initial period. Affordability proofs (like strong rental yields) are required.

What fees should I expect with a commercial property loan?

Arrangement/setup fees (1–2%), valuation costs, borrower and lender legal fees, and sometimes broker/early repayment charges. Always get a full summary of fees before committing.

How does property type affect the rate I’m offered?

Prime, standard-use offices and shops get better rates than more specialised, risky, or mixed-use sites. Energy-efficient and well-located properties are typically cheaper to finance.

Are any costs tax-deductible?

Interest on the commercial loan and some associated costs are tax-deductible as business expenses. Consult an accountant for specifics, as legislation is subject to change.

Will rates go down in 2026?

There is cautious optimism that rates will fall further if inflation remains under control and economic stability holds. However, external shocks or policy shifts could see a return to higher rates, so fixed rate options may appeal for longer-term certainty.

Conclusion

The commercial property loan landscape in the UK remains highly dynamic into 2026, offering a wide range of rates dependent on risk, loan-to-value, and property profile. Businesses looking to buy, invest in, or refinance property should prepare thoroughly, compare all available deals, and factor in not just rates but all fees and future market risks. With careful planning and up-to-date financials, UK business owners can seize the opportunities provided by historically competitive lending—even as economic conditions evolve.
