CoreFi is a broker, not a lender. We do not set rates and lenders make all credit decisions.
In short: A commercial mortgage is a first-charge loan secured against business property, typically £50k to £25M over 10 to 25 years, with owner-occupiers borrowing up to 70% to 75% LTV; rates start from around 2% above the Bank of England base rate, subject to status and lender.
A commercial mortgage is a first-charge loan secured against property your business owns or occupies, repaid over a long term rather than a short window. It is the commercial equivalent of a residential mortgage: the lender registers a legal charge over the building, advances the bulk of the purchase price or the refinanced balance, and you repay capital and interest, or interest only, across the life of the loan. Because the lender holds the property as security for the full term, the rate sits well below any bridging or short-term facility. Buy the premises you already trade from and you stop paying rent to a landlord and start building equity in an asset that sits on your own balance sheet.
Your property is at risk. A commercial mortgage is secured by a first legal charge, so the lender can take possession of and sell the property if the loan is not repaid. Directors who give a personal guarantee can be pursued for any shortfall from their own assets. Borrowing against premises you occupy puts that trading location at risk if the business cannot meet the payments.
Lenders split commercial mortgages into two broad categories, and the distinction drives almost everything that follows. An owner-occupied mortgage is where your business trades from the property it is buying: a manufacturer buying its factory, a dentist buying the surgery, a wholesaler buying the warehouse. A commercial investment mortgage is where you buy the property to let it to a third party, and the rent, not your own trading income, services the debt. Owner-occupiers generally access better terms, because a lender treats a business funding its own premises as lower default risk than a landlord dependent on a tenant who might leave.
Typical rate ranges. We are a broker, not a lender, so we cannot set or promise a rate, and no honest broker can quote one before a lender has underwritten the property and the business. As a guide only, and subject to status, security and the individual lender, variable-rate commercial mortgages are commonly priced from around 2% to 5% above the Bank of England base rate, and fixed-rate products currently sit from 5% to 8% depending on term, loan-to-value and property type. The figure a lender actually offers turns on the strength of the covenant (the borrower's financial standing), the quality and marketability of the property, the loan-to-value, and how long a fixed period you want. Thinner-covenant deals, specialist property, and higher advances all push the rate up. Arrangement fees of 1% to 2% of the loan, a valuation fee, and legal costs on both sides sit on top and should be built into your numbers from the outset.
Loan-to-value and deposit. Loan-to-value (LTV) is the ratio of the loan to the property's value, and it is the first number every lender fixes. On owner-occupied premises backed by a solid trading business, lenders commonly advance 70% to 75% LTV, meaning a deposit of 25% to 30%. A short list of lenders will stretch to 80% on strong owner-occupied cases, and the rate reflects the extra risk. Commercial investment mortgages are usually more conservative, often 65% to 75%, and specialist or harder-to-let property such as a single-tenant unit on a short lease will attract a lower advance still. For trading businesses such as pubs, hotels and care homes, the valuation is frequently based on earnings rather than bricks and mortar, which changes how the LTV ceiling is calculated.
Eligibility and what lenders assess. The property is the security, but affordability decides the loan. The central test is the debt-service coverage ratio (DSCR): the lender wants your net operating income, or the rental income on an investment deal, to cover the mortgage payment with a margin, typically 125% or more, and often stress-tested at a higher notional rate. Beyond that, expect the lender to want two to three years of accounts or a credible trading forecast, business and personal bank statements, details of the directors and their assets, and a clear purpose for the loan. Personal guarantees from directors are standard on limited-company lending. A clean credit profile helps, but adverse credit is not an automatic no with the right lender; it narrows the panel and moves the price. Most UK commercial mortgages are written to limited companies, and many to a separate special-purpose vehicle (SPV) set up to hold the property. Whether to borrow in the trading company or an SPV is a question for your accountant, because stamp duty and corporation tax pull in different directions.
Lender types: high street, challenger, specialist. Who you approach matters as much as the numbers. High-street banks offer the keenest pricing but the narrowest appetite: they favour strong covenants, standard property, and owner-occupiers who already bank with them. Challenger banks lend more flexibly, take SPVs as standard, and will look at investment property and less conventional trading businesses the clearers pass on, at a modest premium to high-street pricing. Specialist lenders occupy the ground nobody else will touch: pubs, care homes, petrol stations, holiday parks, mixed-use blocks with flats above, semi-commercial security, and borrowers with a blemished file. The lender who says yes to a freehold warehouse for a manufacturer is rarely the one who says yes to a leasehold city-centre office or a wet-led pub, and the terms move accordingly. Our job as a broker is to read your case and place it with the lender most likely to say yes on workable terms, rather than letting you shop it around and leave a trail of declines.
Term lengths and repayment. Commercial mortgage terms typically run 10 to 25 years, occasionally longer on strong owner-occupied cases. You can usually choose capital-and-interest repayment, which clears the debt by the end of the term and builds equity faster, or interest-only, which keeps the monthly cost down but leaves the balance outstanding at the end to be refinanced or repaid from a sale. Fixed-rate periods of two, three, five or occasionally ten years let you lock the debt-service cost, which is worth most when you are projecting cash flow against a long lease or a tight DSCR. Early repayment charges usually apply within a fixed period.
Illustrative worked example (for guidance only, not a quote or offer). A trading company buys its warehouse for £600,000 with a 30% deposit of £180,000, borrowing £420,000 at 70% LTV. On a 20-year capital-and-interest mortgage at an assumed 7.5% rate, the monthly payment is roughly £3,384, about £40,600 a year. If the business was previously paying £45,000 a year in rent on the same building, in this example the mortgage would cost less than the assumed rent, and every payment reduces a balance the company owns rather than a landlord's. On top of the deposit, budget an arrangement fee of, say, 1.5% (£6,300), a valuation fee, and legal costs on both sides, usually settled on completion. The lender would test affordability by checking that operating profit covers that £3,384 payment by at least 125%, so it would want to see net operating income of around £4,230 a month or more before approving. Change the rate, the term, or the LTV and every one of these figures moves, which is exactly why a lender prices each case individually.
Why use a broker. We do not set the rate and we will not pretend to. What we do is tell you quickly which lenders are genuinely open to your property type, your covenant and your LTV, model fixed against variable and capital-and-interest against interest-only before you commit, and place your file with the lender most likely to back it first time.
Key Benefits
- Owner-occupied buyers typically access better LTV than investors, because the lender treats the business's own use of the premises as lower default risk
- On a 20-year commercial mortgage the interest cost usually lands below the rent you would pay on the same building, and that gap shows up from month one
- Interest on a commercial mortgage is deductible against business profit; your accountant should model this before you decide whether to buy in the trading company or an SPV, because stamp duty and corporation tax pull in different directions
- A fixed-rate tranche locks your debt-service cost for the fixed period, which is worth most when you are projecting cash flow against a long lease or a tight DSCR
Frequently Asked Questions
How much deposit do I need for a commercial mortgage?
Usually 25% to 30%, meaning lenders advance 70% to 75% LTV. Strong owner-occupied cases can occasionally reach 80%, and the rate reflects the extra risk. Commercial investment properties, especially those on short leases or with a single tenant, tend to attract a lower advance of 65% to 75%. For trading businesses such as pubs, hotels and care homes, the ceiling is often set on earnings rather than bricks and mortar, which can change the deposit required. These are guide figures; the lender fixes the LTV at underwriting.
What interest rates apply to commercial mortgages?
As a guide only, and subject to status and the individual lender, variable rates are commonly priced from around 2% to 5% above the Bank of England base rate, and fixed rates currently sit from 5% to 8% depending on term, LTV and property type. We are a broker, not a lender, so we cannot promise a rate; the lender sets it after underwriting the property, the covenant and the loan-to-value. We can model fixed against variable before you apply so you go in with realistic expectations.
What do lenders look at when deciding whether to lend?
The property is the security, but affordability decides the loan. The key test is the debt-service coverage ratio: lenders want your net operating income, or the rent on an investment deal, to cover the mortgage payment by at least 125%, often stress-tested higher. They will also want two to three years of accounts or a credible forecast, bank statements, director details, and a clear purpose for the loan. Personal guarantees from directors are standard. A clean credit file helps, but the right lender will still consider adverse credit at a higher price.
What is the difference between high-street, challenger and specialist lenders?
High-street banks price keenest but have the narrowest appetite, favouring strong covenants, standard property and existing customers. Challenger banks are more flexible, lend to SPVs as standard, and take on investment property and less conventional trading businesses at a small premium. Specialist lenders cover what the others will not: pubs, care homes, petrol stations, mixed-use blocks, semi-commercial security and blemished credit files. Matching your case to the right category is most of what a broker does.
How long is a commercial mortgage term, and can I pay interest-only?
Terms typically run 10 to 25 years, occasionally longer on strong owner-occupied cases. You can usually choose capital-and-interest, which clears the debt by the end of the term and builds equity, or interest-only, which lowers the monthly cost but leaves the balance to refinance or repay from a sale at the end. Fixed-rate periods of two, three, five or sometimes ten years let you lock the payment. Early repayment charges usually apply during a fixed period.
Can I buy premises through my limited company or an SPV?
Yes, and most UK commercial mortgage lending is structured this way. Whether the loan sits in your trading company or a separate special-purpose vehicle (SPV) set up to hold the property is a question for your accountant, usually turning on stamp duty, corporation tax and what happens if you ever sell the business separately from the property. Lenders are comfortable with SPVs and will require personal guarantees from the directors either way.
Can I get a commercial mortgage on mixed-use or semi-commercial property?
Yes. A building with a commercial unit below and flats above is a routine transaction for lenders who understand mixed-use, though not every high-street bank will touch it. The valuation usually splits the commercial and residential elements and the advance is set against the combined security value. These cases sit more naturally with challenger and specialist lenders, which is where we would place them. We arrange unregulated commercial mortgages only. Where the residential part of a mixed-use property is occupied by you or a member of your family, the loan may be a regulated mortgage contract, which we do not arrange; investment mixed-use let to third parties is unregulated and is the case we can place.
Can I get a commercial mortgage with adverse credit or as a newer business?
Often, yes, though it narrows the panel and moves the price. Commercial mortgage lending is security-led, so a sound property, a workable LTV and a credible income can outweigh a patchy file or a shorter trading history. Some lenders will not touch adverse credit and others specialise in it. No broker can promise approval, which is the lender's decision on your specific file, but we know which lenders are open to the case and route it accordingly.
