Commercial mortgages for business owners and property investors

Whether you are buying premises for your business, acquiring an income-producing asset, or refinancing an existing commercial property, the right funding structure depends on more than simply how much you need to borrow.

Commercial property finance encompasses a wide range of products, lenders, and underwriting approaches, and choosing the wrong route can cost borrowers both time and money.

This guide explains how commercial property finance works in the UK, what lenders look for, how deals are assessed, and how to approach your application strategically from the outset.

What is a commercial mortgage?

A commercial mortgage is a loan secured against a non-residential or mixed-use property. Commercial property finance is the wider term: it covers any mortgage, loan or structured facility secured on that kind of property in the UK.

It covers a broad range of asset types, including offices, retail units, industrial buildings, warehouses, care homes, hotels, student accommodation, and mixed-use properties that combine commercial and residential elements.

Unlike residential mortgages, commercial property finance does not follow a standardised process. Terms, rates, loan-to-value ratios, and underwriting criteria vary significantly between lenders, and deals are assessed on their individual merits rather than through automated scoring models.

The Key Distinction: Owner-Occupied vs Investment Property

The single most important question a lender will ask is how the property is being used, and specifically, whether the borrower intends to trade from the premises or hold the building as an investment.

Owner-occupied commercial mortgages are assessed primarily on the trading performance of the borrowing business. Lenders want to understand turnover, profitability, debt-service coverage, and the financial health of the company occupying the building.

The stronger the business, the more confident a lender will be that the mortgage can be sustained regardless of wider market conditions.

Businesses purchasing or refinancing premises they trade from can explore Owner-Occupied Commercial Mortgages for a more detailed look at this funding route.

Commercial investment mortgages are assessed differently. Here, the rental income generated by the property is the primary consideration. Lenders will examine the passing rent, lease terms, tenant covenant strength, and how comfortably the income covers the interest or mortgage payments.

A property with strong, long-term tenants on institutional leases is far more attractive to lenders than one with short-term or informal arrangements.

For borrowers focused on income-producing assets, Commercial Investment Mortgages cover funding options linked to established commercial investment property.

Understanding which category your property and borrowing purpose falls into is essential before approaching any lender, because the documentation required and the way the deal is underwritten are fundamentally different.

Property Types and How Lenders Categorise Them

Not all commercial buildings are treated the same way. Lenders typically group property into tiers based on liquidity and resale risk, which directly influences the LTV they are willing to offer and the rate they will charge.

Specialist property types require lenders with sector-specific expertise. Approaching a mainstream commercial lender with a care home acquisition or a licensed premises purchase often results in a decline that could have been avoided with better lender selection from the start.

Where a property combines residential and commercial elements, Semi-Commercial Mortgages explain how funding is structured for mixed-use buildings.

How a commercial mortgage is structured

Loan-to-Value and Gross vs Net Advance

Commercial lenders express lending limits as a percentage of the property’s valuation, known as the loan-to-value ratio. An LTV of 65% on a building valued at £1,500,000 produces a gross loan of £975,000.

It is important to distinguish between the gross loan and the net advance. The net advance is the actual amount of money that reaches the borrower after fees have been deducted.

Arrangement fees, valuation costs, and legal fees are sometimes retained from the loan rather than paid separately, which means the usable funds can be meaningfully lower than the headline figure.

Borrowers should always ask a broker to confirm both figures before accepting any facility.

Interest Options

Commercial mortgages are typically available on a capital repayment or interest-only basis, though lenders take different views on each.

Interest-only facilities are common on investment commercial mortgages where rental income is being used to service the loan, preserving cash flow for the investor. Capital repayment facilities are more common on owner-occupied deals where the business is building equity in the property over time.

Interest rates on commercial mortgages are generally set at a margin above the Bank of England base rate or SONIA, though some lenders offer fixed-rate products for borrowers seeking payment certainty.

Fees to Factor In

Borrowers frequently underestimate the total cost of commercial property finance. Common fees include:

• Arrangement fee: Typically 1% to 2% of the gross loan, payable to the lender
• Valuation fee: Varies by property value and type; specialist assets cost more to value
• Legal fees: Both borrower and lender legal costs are usually payable by the borrower
• Broker fee: Paid on completion for placing the deal with the right lender
• Exit fee: Some lenders charge a fee on repayment, particularly on shorter-term facilities

Understanding the full cost of a facility before proceeding is essential to accurate investment appraisal.

A realistic commercial mortgage example

Illustrative figures only. Actual rates, fees and loan amounts depend on the lender and your circumstances.

To illustrate how costs and loan mechanics work in practice, consider the following scenario.

A property investor is purchasing a high street retail unit for £900,000. The lender agrees to fund at 65% LTV on an interest-only basis at a rate of 6.5% per annum.

• Gross loan: £585,000
• Arrangement fee (1.5%): £8,775
• Net advance (after fee retention): £576,225
• Monthly interest: £3,168.75
• Annual interest cost: £38,025
• Passing rent: £52,000 per annum
• Interest coverage ratio: 1.37x (lender minimum typically 1.25x)

At the end of a five-year term, the borrower would repay the original gross loan of £585,000 from proceeds of a sale or refinance. The lender charges no exit fee in this example, but a borrower should always confirm this at the outset rather than assuming.

What Lenders Look For

On Investment Deals

• Rental income and how comfortably it covers loan payments (interest coverage ratio)
• Lease length and remaining term
• Tenant covenant strength (the financial standing of who is paying the rent)
• Location and property liquidity (how easily could the building be sold if required)
• Borrower experience in managing commercial property

On Owner-Occupied Deals

• Business trading history (typically two to three years of accounts)
• Profitability and debt-service coverage
• Director or shareholder personal financial position
• Any existing borrowing secured against other assets
• Future business plans and sustainability of turnover

A lender assessing an owner-occupied purchase will want to be satisfied that the business generating the income is fundamentally sound. A profitable business in a growing sector presents a very different risk profile to a cyclical or declining one, even if the current figures look similar on paper.

Purchase, Refinance, and Capital Release

Commercial property finance is not used exclusively for purchases. There are several common borrowing purposes, each with slightly different considerations.

Purchase: Funding the acquisition of a commercial or mixed-use building. The lender will assess the transaction price and the independent valuation, lending against whichever is lower.

Refinance: Replacing an existing commercial mortgage, usually to secure improved terms, release equity, or restructure debt ahead of a lease expiry or portfolio review.

Capital release: Borrowing against an unencumbered commercial property or increasing an existing mortgage to release funds for reinvestment, development, or business purposes.

Debt restructuring: Consolidating multiple commercial facilities into a single, more manageable structure, often used by portfolio investors looking to simplify their borrowing.

Common Mistakes That Delay or Derail Applications

Many commercial property finance applications run into problems that are entirely avoidable with proper preparation. The most frequent issues include:

1. Approaching a lender without understanding how they categorise the asset type
2. Underestimating the time it takes to complete a commercial valuation
3. Providing incomplete financial accounts or management information
4. Failing to agree solicitors early, which causes delays at the legal stage
5. Not having a clear and credible exit strategy in place
6. Overlooking tenant-related issues such as break clauses, rent reviews, or lease expiries that affect income security
7. Assuming the same lender that funded a previous deal is automatically the best fit for the next one

Working with a specialist commercial finance broker reduces the risk of all of the above.

A broker with genuine market access can identify the most suitable lender for your specific asset type, borrower profile, and deal structure before you commit time and money to an application.

Why Lender Fit Matters More Than Rate Alone

It is tempting to focus exclusively on interest rate when comparing commercial mortgage options, but lender fit is often more important, particularly on complex or specialist deals.

The same building can be viewed very differently by different lenders. A warehouse on an out-of-town estate might attract a competitive rate from a mainstream commercial lender, whilst a mixed-use property in a secondary location may require a specialist lender willing to look beyond straightforward metrics.

Choosing the wrong lender for a given asset type does not just mean a higher rate; in many cases it results in an outright decline.

What a commercial mortgage broker does

A commercial mortgage broker introduces your case to lenders and manages it through to completion. It does not lend its own money. Go direct to one bank and you get that bank's view of your property and one set of terms. A broker adds three things:

• Finding lenders whose appetite fits. Lenders differ in the property types, sectors and loan sizes they accept. A broker matches the asset and the sector to lenders that want that kind of business, including specialist lenders that do not deal with borrowers direct.
• Packaging the case. Accounts, leases, property details and the purpose of the loan are set out in the form an underwriter needs, with any weak points explained at the start.
• Managing the valuation and legal stages. The broker keeps the valuer, the solicitors and the lender moving and deals with queries as they come up.

Brokers are paid in one of three ways: a fee you pay, a commission from the lender, or both. Ask for the amount, and when it is payable, in writing before you commit to an application.

Commercial mortgages for specialist sectors

In some sectors the building and the business cannot be separated. The valuer assesses them together as a trading business, the lender reads the trading accounts as closely as the valuation, and fewer lenders are active.

Care homes

Lenders look at occupancy, fee income, staffing costs and the home's trading accounts. They also check its registration and latest inspection rating with the care regulator, and the experience of the operator and the registered manager. A care home is hard to put to another use, so fewer lenders will consider one than an office or a shop.

Hotels and guest houses

A hotel is assessed on its trade: occupancy, room rates, how seasonal the income is and how much of it depends on the owner's own work. Lenders want a run of trading accounts and an operator with experience in hospitality. A guest house where the owner lives on site also has a residential element, which changes which lenders will consider it.

Pubs and restaurants

Lenders look at the split between drink and food sales, a pub's barrelage (the volume of beer it sells) and whether it is free of tie or tied to a brewery or pub company. They check the premises licence, the food hygiene rating and the operator's record in the trade. Not every commercial lender takes licensed premises, so the choice is smaller.

Living accommodation matters in any of these sectors. Where 40% or more of the floor area is a dwelling and you borrow in your own name, the loan can be a regulated mortgage contract, and you should expect that if you or a close relative will live there. Our page on semi-commercial mortgages explains the test.

Refinancing a commercial mortgage

If you already have a commercial mortgage, the questions change: what it costs to leave your current lender, how the property will be valued today and whether the saving or the equity released justifies the fees. Our page on commercial remortgages covers early repayment charges, valuation, capital raising and the alternatives to moving lender.
