From 6%: Broker Checked UK Commercial Mortgage Rates and Costs, 2026
Indicative UK commercial mortgage pricing in 2026 runs from around 6% for well-placed term debt, rising through 8% for development finance and higher still for bridging. Every quote is bespoke, built from a reference rate, lender margin and fees specific to your deal. The next step is getting a broker-checked quote against your actual figures rather than a headline rate.
TL;DR:
- Most well-secured UK commercial term loans start around 6% per annum, rising to 7%–9% depending on deal specifics such as LTV and asset type.
- Development finance typically begins from 8% annually, while bridging loans are charged monthly from about 0.75%, which annualizes to over 9%.
- Commercial mortgage rates are composed of a reference rate, a lender margin influenced by risk factors, and applicable fees, with margins lower for deals with stronger covenant and lower LTV.
- Fixed rates are better for long-term certainty, especially with longer hold periods, but short fixes or trackers may be more cost-effective if planning to refinance or sell within three years.
- Proper comparison of offers requires analyzing total costs over the intended holding period, including fees, to identify the most economical borrowing option.

What are typical UK commercial mortgage rates right now?
Well-secured commercial term loans against a trading business or an investment property with a strong tenant commonly start around 6% per annum for the strongest deals, with many borrowers landing somewhere in the 7% to 9% range once loan-to-value, asset type and covenant strength are factored in. Indicative pricing across the UK market confirms these floors, though every lender adjusts them for risk.
Development finance sits higher again, with facilities often starting from around 8% per annum given the additional risk of a construction or conversion project. Bridging loans are priced monthly rather than annually, typically from around 0.75% per month, which sounds modest until you annualise it.
| Finance type | Indicative starting rate | Typical structure |
|---|---|---|
| Commercial term mortgage | From around 6% p.a. | Fixed or variable, longer term |
| Development finance | From around 8% p.a. | Drawn in stages against build cost |
| Bridging loan | From around 0.75% per month | Short term, 1 to 18 months |
A worked example helps make sense of these numbers.
A few points to keep in mind when reading any headline figure:
- Rates quoted online are almost always “from” prices reserved for the lowest-risk deals.
- Development and bridging finance carry higher rates because the lender is taking on construction or exit risk, not just property risk.
- A rate that looks high in isolation can still be the cheapest overall option once fees and terms are compared properly.
How is your commercial mortgage rate actually built?
Every commercial mortgage rate is built from three components: a reference rate, a lender margin and a set of fees. Strip away the marketing and that formula explains almost every price difference you’ll see between lenders.
The reference rate is either the Bank of England base rate, SONIA (the Sterling Overnight Index Average that has replaced LIBOR as the standard benchmark for variable pricing), or a swap rate for fixed deals. Fixed and variable commercial pricing is built on top of whichever benchmark applies, then the lender adds its margin.
Lender margin is where your deal quality really shows up. It moves according to:
- Loan-to-value: lower leverage almost always buys a lower margin.
- Asset type: a modern industrial unit prices differently to a pub or a care home.
- Covenant strength: a long lease to a strong tenant, or healthy trading accounts for an owner-occupier, both reduce perceived risk.
- Loan term: longer terms sometimes carry a small premium for the extra uncertainty.
Pro Tip: Ask every lender to break their quote into reference rate, margin and fees separately. It’s the fastest way to spot who’s actually offering the sharpest deal versus who’s just quoting the lowest headline number.
Fees add up too.
Should you fix or go variable on a commercial mortgage?
Fixed rates suit borrowers who want payment certainty and plan to hold the property for several years; variable rates suit those expecting to refinance, sell, or who have generous income cover to absorb rate movements.
Fixed commercial mortgage pricing is set from swap rates, not directly from the Bank of England base rate. When swap rates diverge from Bank Rate, as has happened through parts of 2026, fixed pricing can move independently of any base rate change, catching borrowers off guard who assumed the two always track together. Analysis of that repricing shows fixed deals sometimes cost more than the base rate alone would suggest.
A shorter fix, often two to three years, has become common in 2026 because it avoids locking into a swap curve that may fall later, while still giving payment certainty through the immediate period. Tracker and standard variable rate (SVR) products move directly with the base rate, which suits borrowers comfortable with some payment fluctuation.
Three practical rules for choosing:
- If you plan to sell or refinance within three years, a tracker or short fix usually avoids paying for certainty you don’t need.
- If your debt service coverage ratio (DSCR) has little headroom, a fixed rate protects against payment shocks that could breach loan covenants.
- If swap rates are notably above the base rate when you’re quoting, compare the total cost of a short fix against a tracker before committing either way.
DSCR versus ICR: how your borrower type changes the price
Owner-occupiers and investors get assessed completely differently, and that difference directly affects the rate and loan-to-value you’re offered.
Owner-occupiers are underwritten primarily on debt service coverage ratio (DSCR), which measures whether trading profit comfortably covers the mortgage payment. Lenders typically want to see DSCR of at least 1.25 to 1.5 times the annual repayment, drawn from filed accounts, management accounts and sometimes forward projections.
Investors are assessed on interest coverage ratio (ICR), which looks at rental income against the interest cost, alongside a close look at tenant covenant strength. A single tenant on a long lease with a strong credit profile will always price better than a multi-let building with short leases or void periods.
- Owner-occupiers: DSCR-focused, needs accounts and trading history.
- Investors: ICR-focused, needs lease terms and tenant financials.
- Both: loan-to-value bands commonly sit between 60% and 75%, with stronger DSCR or ICR sometimes unlocking a higher LTV or a better margin.
Semi-commercial properties, where a residential flat sits above a shop, follow their own deposit and LTV rules that blend both assessment styles.
What does a commercial mortgage really cost once fees are added?
Headline rates mislead when fees and loan-to-value differences are ignored. Comparing two offers properly means looking at total cost over your intended holding period, not just the interest rate on the page.
Arrangement fees generally run 1% to 2%, with valuation and legal costs adding a few thousand pounds depending on property size and complexity.
A worked comparison shows why this matters:
| Offer | Rate | Arrangement fee | 5 year total cost on £500,000 |
|---|---|---|---|
| Offer A | around 6% | 1–2% (varies by deal) | Roughly £172,500 |
| Offer B | around 7% | about 1% (depending on property value) | Roughly £177,500 |
Offer A looks more expensive on fees but wins on total cost because the lower rate compounds across five years. Comparing total borrowing cost rather than the headline figure is the only reliable way to judge two offers fairly.
To compare properly:
- Convert every fee into a pound figure, not a percentage, so you can add it directly to interest cost.
- Model the total cost over your actual expected holding period, not just year one.
- Factor in any exit fee if you might repay or refinance early.
What do lenders want to see before they’ll quote your best rate?
Lenders want proof that your income, whether trading profit or rental income, comfortably supports the loan before they’ll offer their sharpest pricing. Getting your paperwork right before you approach anyone shortens the process and often improves the rate you’re offered.
You’ll typically need:
- Two to three years of filed accounts or self-assessment returns for owner-occupiers.
- A current rent roll and lease summaries for investment property.
- Recent management accounts showing trading is stable or improving.
- A clear plan for the property, particularly for development or refurbishment finance.
- Proof of identity and company details, which lenders often verify against Gov.
Pro Tip: Lenders reward clarity. A tidy rent roll with lease end dates and tenant names laid out plainly often does more for your margin than a slightly lower starting LTV.
The levers within your control are lowering your LTV where possible, presenting the strongest coverage ratio the numbers support, and having lease or trading evidence ready rather than promised. Start shopping around three to six months before you need the facility, whether that’s a purchase completion or an existing loan reaching maturity, because rushed refinancing rarely gets the best terms.
Broker point of view: how Prosper Home Loans helps commercial borrowers
CeMAP and CeRER-qualified advisors with whole-of-market access across commercial, semi-commercial and specialist lending often find that presenting a clean rent roll and stronger DSCR upfront can shift a lender’s margin noticeably compared with initial borrower submissions. Contacting a broker early, before you need the facility, can allow for an initial market search plus a written comparison of realistic options.
A simple rule-of-thumb for 2026 borrowing decisions
The 2026 market rewards borrowers who plan around holding period, not headline rates. Short hold or tight DSCR headroom, favour a tracker or short fix; long hold with solid coverage, a longer fix earns its keep. Stress-test both with a broker before you sign.

How Prosper Home Loans gets you a market-checked rate
A local alternative to guessing your way through commercial lenders alone is to use independent, whole-of-market advisors, with specialist experience in semi-commercial, bridging and foreign national cases that many high-street lenders won’t touch.
When you enquire, we’ll ask for the same core documents lenders want, your accounts or rent roll, lease summaries and identity details, then run a genuine market search rather than pushing a single panel product. You’ll get a written comparison showing rate, margin and fees side by side, so you can see total cost rather than just a headline number. Rates for bridging finance and fixed versus tracker structures both benefit from this same comparison approach.

FAQ
What is a good interest rate on a commercial mortgage?
The only reliable way to know if your quote is competitive is comparing it against a current market search for a similar deal.
Is a 6% commercial mortgage rate high or low in the UK?
Most commercial borrowers should expect pricing somewhat above this floor once fees and risk factors are added.
Is 3.75% a good mortgage rate for a commercial property?
A rate that low would be unusually cheap for commercial lending in the current market and isn’t typical of standard commercial mortgage pricing in 2026. If you’ve seen that figure quoted, check whether it refers to residential lending or a heavily discounted introductory period rather than a standard commercial facility.
Is it possible to get a 100% commercial mortgage?
Genuine 100% commercial mortgages are rare because lenders generally expect a deposit of 25% to 40%, giving loan-to-value bands of roughly 60% to 75%. Higher leverage sometimes appears through additional security or blended lending structures, which a broker like Prosper Home Loans can help explore based on your specific assets.
