Commercial Mortgages: How They Work

What is a commercial mortgage?

A commercial mortgage is a loan secured against commercial property, used to purchase premises for your own business use or as an investment to rent out. Commercial property includes offices, shops, warehouses, factories, pubs, restaurants, and mixed-use buildings with both commercial and residential elements.

Unlike residential mortgages, commercial mortgages are not regulated by the FCA (unless the property has a residential element). This means terms and conditions vary more widely between lenders, and there is less standardisation in the application process. Working with a specialist broker who understands the commercial lending market is particularly important.

How does a commercial mortgage differ from a residential mortgage?

• Deposit: Commercial mortgages typically require a 25% to 40% deposit, compared to 5% to 25% for residential mortgages
• Interest rates: Commercial rates are higher, typically 2% to 6% above base rate
• Term: Usually 15 to 25 years, though some lenders offer up to 30 years
• Assessment: Lenders assess the business's ability to service the debt, the property's value, and its potential rental income
• Fees: Arrangement fees are typically 1% to 2% of the loan amount, plus legal and valuation fees
• Regulation: Not regulated by the FCA in most cases

Types of commercial mortgage

Owner-occupier mortgages

For businesses buying premises they will operate from. The lender assesses the business's trading performance and ability to make repayments from its normal cash flow. Owner-occupier mortgages are available to limited companies, partnerships, LLPs, and sole traders.

Commercial investment mortgages

For buying commercial property to rent out to tenants. The lender focuses primarily on the rental income the property will generate relative to the mortgage payments. They typically require rental income to cover at least 125% to 150% of the mortgage payment. The tenant's covenant strength (their financial stability) is also assessed.

Semi-commercial mortgages

For mixed-use properties that combine commercial and residential elements, such as a shop with a flat above. These can be more complex to arrange because they potentially span both regulated and unregulated lending.

What deposit do you need for a commercial mortgage?

Most commercial mortgage lenders require a deposit of 25% to 40% of the property's purchase price. This means the maximum loan-to-value (LTV) ratio is typically 60% to 75%. Some specialist lenders offer up to 80% LTV for strong applications, but this is less common and comes with higher interest rates.

If you do not have a large cash deposit, you may be able to use equity in other properties (commercial or residential) as additional security, or use a bridging loan to cover a short-term gap while arranging longer-term finance.

What interest rates can you expect?

Commercial mortgage rates are typically expressed as a margin above the Bank of England base rate or SONIA (Sterling Overnight Index Average). Current typical rates in the UK:

• Strong applications (good trading, 30%+ deposit): Base rate + 2% to 3%
• Standard applications: Base rate + 3% to 5%
• Higher risk (new businesses, specialist properties): Base rate + 5% to 8%

Fixed rate options are available, typically for two to five years, after which the rate reverts to a variable rate. Fixed rates provide payment certainty but may include early repayment charges if you want to repay or refinance during the fixed period.

What do lenders look for in a commercial mortgage application?

• Business trading history: At least two years of filed accounts, ideally three or more
• Profitability: Sufficient profit to comfortably cover the mortgage payments
• Property type and condition: Standard property types are easier to finance than specialist or unusual premises
• Location: Properties in areas with strong demand are viewed more favourably
• Personal credit history: Directors' personal credit is assessed alongside business financials
• Deposit size: A larger deposit reduces the lender's risk and improves your rate
• Existing debt: Your overall debt position, including existing loans and credit facilities

The application process

1. Initial enquiry: A broker or lender assesses your situation and provides an indication of what is achievable
2. Decision in principle: A preliminary approval based on the information provided, subject to valuation and full underwriting
3. Valuation: The lender instructs a surveyor to value the property. Commercial valuations are more complex and expensive than residential ones, typically costing £1,000 to £5,000 depending on the property
4. Full underwriting: The lender reviews all documentation, accounts, bank statements, and the valuation report
5. Offer: A formal mortgage offer is issued detailing all terms and conditions
6. Legal work: Solicitors handle the legal transfer of the property and register the lender's charge
7. Completion: Funds are released and the property purchase completes

The entire process typically takes 6 to 12 weeks from application to completion, though complex cases can take longer.

Tax implications of commercial property

Commercial property purchases may be subject to Stamp Duty Land Tax (SDLT) in England and Northern Ireland, or equivalent taxes in Scotland (LBTT) and Wales (LTT). Mortgage interest on commercial property is typically deductible as a business expense. Capital allowances may be available on certain fixtures and fittings within the property. Speak with an accountant about the specific tax implications for your situation.

How a broker helps with commercial mortgages

The commercial mortgage market is not as transparent as the residential market. Rates, criteria, and available products are not always published publicly, and many lenders work exclusively through brokers. A business finance broker with commercial mortgage experience can access the full market, negotiate on your behalf, and guide you through the more complex application process.

Why Is Understanding Commercial Mortgages: How They Work Important?

Making informed decisions about commercial mortgages: how they work can have a significant impact on your financial wellbeing, both in the short term and over the long run. In the UK, where regulation and consumer protections are strong, understanding your rights and options puts you in a much better position.

Many people make decisions about commercial mortgages: how they work based on incomplete information, assumptions, or advice from well-meaning friends and family who may not fully understand the current rules and options. Taking the time to research properly can save you thousands of pounds over the lifetime of a product or arrangement.

The UK financial market is competitive, which means there are usually multiple options available for any given need. The challenge is identifying which option genuinely suits your circumstances rather than just choosing the first or cheapest.

What Are the Key Considerations in the UK?

When it comes to commercial mortgages: how they work in the UK, there are several important factors that are specific to the British market and regulatory environment. These considerations can significantly affect the options available to you and the value you receive.

UK-specific factors include the tax regime (income tax, capital gains tax, inheritance tax, and stamp duty land tax), the regulatory framework (FCA rules, consumer duty, and FSCS protection), and the structure of the market (whole-of-market brokers, restricted advisers, and direct providers).

• Tax implications — understand how UK tax rules affect the cost and benefit of your decision
• FCA regulation — ensure any provider or adviser you use is authorised and regulated
• Consumer protections — know your rights under the Consumer Duty, FSCS, and FOS
• Market comparison — the UK market is competitive, so always compare multiple options
• Professional advice — for complex decisions, regulated advice provides accountability and recourse
• Documentation — keep records of all communications, agreements, and transactions

What Are the Most Common Mistakes to Avoid?

Experience shows that people consistently make certain mistakes when dealing with commercial mortgages: how they work. Being aware of these common pitfalls can help you avoid costly errors.

One of the most frequent mistakes is not shopping around. UK consumers who compare at least three quotes typically save 20-40 percent compared to those who accept the first offer. Another common error is focusing solely on price rather than the overall value and suitability of the product.

• Not comparing enough options before committing
• Choosing the cheapest option without understanding what is excluded
• Failing to read the terms and conditions and key facts document
• Not disclosing relevant information on the application
• Forgetting to review and update arrangements as circumstances change
• Trying to handle complex situations without professional advice

How Does the Process Work Step by Step?

Understanding the process from start to finish removes uncertainty and helps you prepare properly. Here is what to expect when dealing with commercial mortgages: how they work in the UK.

The timeline varies depending on the complexity of your situation, but for most people the process can be completed within a few days to a few weeks.

1. Step 1: Assess your needs — be clear about what you need and why before approaching providers

4. Step 4: Apply — complete the application accurately and provide all requested documentation
