The Complete Guide to Commercial Mortgages in the UK

Commercial mortgages are long-term loans secured against commercial or mixed-use property, used either to purchase business premises, acquire investment property, or refinance existing borrowing. Unlike residential mortgages, commercial mortgages are individually negotiated -- rates, terms, covenants, and structures are all tailored to the specific property, borrower, and business case.

At Commercial Mortgage Broker, we arrange commercial mortgages across every major property class: offices, retail units, industrial and logistics warehouses, care homes, hotels, pubs and restaurants, medical surgeries, nurseries, petrol stations, and mixed-use buildings with both commercial and residential elements. Our clients range from owner-occupier businesses purchasing their first trading premises to institutional-grade investors assembling multi-million-pound portfolios.

The commercial mortgage market is fundamentally different from residential lending. There is no standardised product range -- every application is individually underwritten against two key pillars: the strength of the borrower (or the borrower's business) and the quality of the underlying property and its income stream. For owner-occupied properties, lenders focus on the trading performance and profitability of the business, typically requiring two to three years of filed accounts, management accounts, and cash flow projections. For investment properties, the emphasis shifts to the rental income, tenant covenant strength, lease length and terms, and the property's marketability should the lender need to realise their security.

Understanding debt service coverage ratios is central to commercial mortgage underwriting. Most lenders require rental or business income to cover mortgage payments by a ratio of at least 1.25 to 1.40 times, calculated at a stressed interest rate. This means the property or business must generate significantly more income than the mortgage costs, providing a buffer for unexpected downturns or rate increases. The exact coverage ratio required varies by lender, property type, and borrower quality.

Commercial mortgage terms typically range from five to twenty-five years, with fixed-rate periods of two to five years before reverting to a variable rate tied to Bank of England Base Rate or SONIA. Interest-only periods are common, particularly for investment properties where the income stream is strong. Some lenders offer fully interest-only terms for the full duration, while others require capital and interest repayment from day one or after an initial interest-only period.

The deposit requirements for commercial mortgages reflect the additional complexity and risk involved. Most lenders require a minimum deposit of twenty-five to thirty per cent, equating to a maximum loan-to-value of seventy to seventy-five per cent. Certain property types -- specialist assets such as hotels, care homes, and licensed premises -- may attract lower maximum LTVs of sixty to sixty-five per cent due to their limited alternative use. Conversely, strong owner-occupied businesses with excellent trading records may achieve up to seventy-five per cent LTV from supportive lenders.

How Commercial Mortgages Works

From initial enquiry to completion, here is what to expect at every stage.

1

Investment Commercial Mortgages

For landlords purchasing tenanted commercial property. Affordability assessed on rental income from tenants, with DSCR (Debt Service Coverage Ratio) being the key metric. Lenders require rental income to cover debt service by 1.25-1.40x at a stressed interest rate, providing a buffer for rate rises and void periods.

2

Owner-Occupied Commercial Mortgages

For businesses purchasing premises to trade from. Assessed on business accounts, trading history, and profitability over two to three years. Often better terms as lenders view owner-occupier commitment favourably. Personal guarantees from directors are standard.

3

Mixed-Use & Semi-Commercial

Buildings combining commercial ground-floor use with residential upper floors occupy a unique position. Some lenders treat these as commercial throughout, while others offer hybrid products recognising the residential element. The ratio of commercial to residential floor space typically determines which regime applies. We have deep experience structuring these deals.

Frequently Asked Questions

Everything you need to know about commercial mortgages.

How are commercial mortgages assessed differently from residential mortgages?

Commercial mortgages are assessed on both the borrower's financial strength and the property's income-generating potential, whereas residential mortgages focus primarily on personal income and affordability. For commercial applications, lenders examine business accounts, cash flow, profitability, sector risk, and the financial positions of directors and guarantors. For investment properties, rental coverage — typically 125% to 140% of mortgage costs at a stressed interest rate — is the primary metric. Commercial valuations are far more detailed, considering tenant covenant strength, lease terms, rent review mechanisms, dilapidations risk, and the property's marketability. The entire underwriting process is manual and individually assessed, rather than automated as with most residential lending.

What deposit is needed for a commercial mortgage?

Most commercial mortgages require a minimum deposit of 25% to 30%, translating to a maximum loan-to-value of 70% to 75%. The exact requirement depends on several factors: owner-occupied businesses with strong financials and long trading histories may achieve 75% LTV from supportive lenders, while investment properties with shorter leases or weaker tenants may be capped at 60% to 65% LTV. Specialist property types — hotels, care homes, pubs, and petrol stations — typically attract maximum LTVs of 60% to 65% because they have limited alternative use and a smaller pool of potential buyers if the lender needs to realise their security.

How long does the commercial mortgage application process take?

From initial application to completion, a straightforward commercial mortgage typically takes 8 to 12 weeks. More complex cases — involving multiple properties, corporate group structures, specialist property types, or environmental or planning considerations — can take 3 to 4 months. Key factors affecting the timeline include the speed of commercial valuation (2-4 weeks), completeness of financial information provided, complexity of legal work on commercial leases, and lender credit committee scheduling. We recommend starting the process as early as possible and having all financial documentation prepared before submitting the application to avoid unnecessary delays.

Can I get a commercial mortgage for a property my business will occupy?

Yes, owner-occupied commercial mortgages are widely available and often attract better terms than pure investment commercial mortgages. Lenders view owner-occupation favourably because you have a strong personal incentive to maintain mortgage payments in order to protect your business premises. You will need to demonstrate that your business is consistently profitable and can comfortably afford the mortgage payments, typically evidenced through 2-3 years of filed accounts, up-to-date management accounts, and cash flow forecasts. Start-up businesses without trading history face more limited options but can sometimes secure lending where the directors have strong personal financials and relevant sector experience.

What is the difference between an owner-occupied and investment commercial mortgage?

An owner-occupied commercial mortgage is for a property where your business will trade from the premises — you are both the borrower and the tenant. An investment commercial mortgage is for a property you are purchasing to let to a third-party tenant and generate rental income. The key differences in lending terms are: owner-occupied mortgages are assessed primarily on your business's financial performance and ability to service the debt, while investment mortgages focus on the rental income, tenant quality, and lease terms. Owner-occupied loans may offer slightly higher LTVs and lower rates because the lender has the comfort of your business's ongoing commitment to the property.

Do I need a personal guarantee for a commercial mortgage?

In almost all cases, yes. Even when borrowing through a limited company or SPV, commercial mortgage lenders require personal guarantees from directors or significant shareholders. The guarantee typically covers the full loan amount and means that if the company defaults and the property sale does not cover the outstanding debt, the guarantor is personally liable for the shortfall. Some lenders may accept limited guarantees capped at a percentage of the loan, or may release guarantees once the loan-to-value falls below a certain threshold. Understanding the guarantee obligation is essential before entering into any commercial mortgage commitment.

Can I get a commercial mortgage on a mixed-use property?

Yes, mixed-use properties — typically buildings with commercial use on the ground floor and residential accommodation above — are a common use case for commercial mortgages. The lending approach depends on the split between commercial and residential floor space. Properties that are predominantly commercial are treated as commercial mortgages throughout. Where the residential element exceeds around 40% to 50% of the overall floor space, some lenders offer semi-commercial or hybrid products with terms that reflect the lower risk profile of the residential element. We specialise in structuring mixed-use deals and know which lenders offer the most competitive terms for different configurations.

What are the typical interest rate structures for commercial mortgages?

Commercial mortgages typically offer a choice between fixed rates and variable rates. Fixed rates lock your interest rate for a period of 2 to 5 years, providing payment certainty, and are quoted as an all-in rate. Variable rates are usually expressed as a margin above Bank of England Base Rate or SONIA, meaning your payments move with the prevailing interest rate environment. Some lenders offer tracker rates with no early repayment charges, providing flexibility to exit or refinance. The rate offered depends on LTV, property type, borrower strength, and loan size — larger loans to strong borrowers on prime properties attract the most competitive pricing.

Can I refinance my existing commercial mortgage?

Absolutely. Refinancing an existing commercial mortgage is one of the most common reasons clients approach us. Reasons to refinance include securing a lower interest rate when your current deal expires, switching from a variable to a fixed rate for payment certainty, releasing equity that has built up through capital repayment or property value increases, consolidating multiple commercial loans, or restructuring terms to better suit your current business needs. We compare your existing terms against the whole market to ensure any refinance genuinely improves your position after accounting for all costs including any early repayment charges on your current facility.

How do commercial mortgage lenders assess tenant quality?

For investment commercial mortgages, tenant quality — known as tenant covenant strength — is a critical factor in the lending decision. Lenders assess tenants on their financial standing using credit checks, filed accounts, and company reports. National and multinational tenants with strong balance sheets represent the strongest covenants. SME tenants are assessed on their profitability, track record, and sector. Lenders also consider the lease terms: longer unexpired terms (ideally 5+ years), full repairing and insuring obligations, upward-only rent reviews, and limited break clauses all strengthen the lending proposition. A property let to a government tenant on a 15-year FRI lease will attract very different terms from one let to a start-up on a 12-month rolling agreement.

What LTV can I get on a commercial mortgage?

Maximum LTV varies by property type and borrower strength. Investment properties typically achieve 65-70% LTV. Owner-occupied premises with strong trading accounts can reach 75-80% LTV. Specialist properties such as pubs, care homes, and hotels are usually capped at 60-65% LTV due to their limited alternative use and smaller buyer pool. Higher deposits consistently attract better interest rates.

What accounts do I need for a commercial mortgage?

For investment properties: tenant leases, rental history, and schedule of any other properties owned. For owner-occupied: 2-3 years filed business accounts, up-to-date management accounts if the year-end is more than 6 months old, business bank statements, and asset and liability statements for all directors and guarantors. Start-up businesses without trading history face more limited options but can sometimes secure lending where directors have strong personal financials and relevant sector experience.

How long does commercial mortgage approval take?

Typically 6-12 weeks from application to completion for straightforward cases. Complex multi-let properties, specialist assets, or applications involving corporate group structures can take 12-16 weeks. Key factors affecting timeline: speed of commercial valuation (2-4 weeks), completeness of financial information provided, complexity of legal work on commercial leases, and lender credit committee scheduling. We recommend starting the process as early as possible.

Can I get a commercial mortgage with adverse credit?

Specialist lenders will consider adverse credit where the property income is strong and the overall deal fundamentals are sound. Expect higher rates and lower LTV limits. Recent bankruptcy or active CCJs require specialist adverse credit lenders. Demonstrating improved financial management and being transparent about credit history from the outset significantly improves your chances.

What is the difference between an owner-occupied and investment commercial mortgage?

An owner-occupied commercial mortgage is for a property where your business will trade from the premises. An investment commercial mortgage is for a property you are purchasing to let to a third-party tenant. Owner-occupied loans are assessed primarily on your business's financial performance, while investment mortgages focus on rental income, tenant quality, and lease terms. Owner-occupied loans may offer slightly higher LTVs because the lender has the comfort of your business's ongoing commitment to the property.

Do I need a personal guarantee for a commercial mortgage?

In almost all cases, yes. Even when borrowing through a limited company or SPV, commercial mortgage lenders require personal guarantees from directors or significant shareholders. The guarantee typically covers the full loan amount and means that if the company defaults and the property sale does not cover the outstanding debt, the guarantor is personally liable for the shortfall. Some lenders may accept limited guarantees capped at a percentage of the loan.
