What are typical business finance interest rates in the UK in 2026?

There is no single business finance rate, because each product prices in its own unit: term loans quote an APR, credit lines a monthly rate, invoice finance a discount fee and merchant cash advances a factor rate. The table below shows the typical ranges we see across Fundably’s 50+ lender panel.

ProductTypical pricing (2026)Priced as
Unsecured term loan6% to 40%+ APRAnnual rate on full balance
Secured term loanFrom around 7% APRAnnual rate, security dependent
Credit line0.5% to 3% per month on drawn balance (roughly 6% to 43% APR)Monthly rate on what you draw
Invoice finance3% to 12% equivalent APR, plus 0.5% to 3% of turnover service fee if factoringDiscount fee on funded balance
Merchant cash advanceFactor rate 1.09 to 1.50Fixed total repayment
Revenue-based financeFactor rate 1.06 to 1.35Fixed total repayment
Asset financeUsually below unsecured pricing, since the asset is securityAnnual rate or fixed instalments
Start Up Loan (government)6% fixedAnnual rate, no fees

All rates shown are indicative only and subject to individual lender assessment. The range within each product is wider than the gap between products, which is why the rate your business is offered matters more than the product’s reputation for being cheap or expensive.

Why is there no single business loan rate?

Lenders price risk, and risk lives in the specifics of your business. The same £50,000 unsecured loan can price at 8% for a five-year-old business with steady revenue and at 30% for a young business in a volatile sector. Since alternative lenders each have their own credit models, the same application can receive materially different offers on the same day, and lenders such as iwoca, Funding Circle and Nucleus Commercial Finance will not agree with each other about your business. That disagreement is exactly what a multi-lender application exploits.

How do you compare products that price in different units?

Convert everything to total cost of borrowing in pounds over the period you will actually use the money. Here is £30,000 for roughly 12 months under three different structures:

StructurePricingTotal cost over ~12 months
Term loan at 12% APR, 12-month termInterest on reducing balanceRoughly £2,000
Credit line at 1.5% per month, fully drawn for 6 of 12 monthsInterest only while drawnRoughly £2,700 if fully drawn all year, half that if drawn for 6 months
Merchant cash advance at 1.25 factor rateFixed total repayment£7,500 regardless of timing

The comparison is not as one-sided as it looks. The credit line costs nothing in the months you do not use it, and the MCA’s repayments flex with your takings, so a quiet month never produces a missed payment. The point of the exercise is that an APR, a monthly rate and a factor rate cannot be compared directly: put them all in pounds over your realistic usage pattern first. Our guide to the types of business finance covers which structure fits which problem.

What determines the rate your business is offered?

Across the panel, five factors move pricing more than anything else:

  • Trading history: most lenders price down meaningfully after 2 to 3 years of accounts; under 12 months restricts the panel
  • Revenue level and consistency: steady monthly revenue prices better than the same total arriving in spikes
  • Security: an asset or debtor book behind the facility typically cuts the rate versus unsecured borrowing
  • Existing commitments: returned payments and heavy existing repayments are among the strongest negative signals in SME credit
  • Sector: lenders maintain sector appetites that shift over time, which is another reason single-lender quotes mislead

How do you get a better rate?

Three moves reliably improve offers. First, compare rather than accept: applying through Fundably puts one application in front of 50+ lenders with a soft credit check at the matching stage, so collecting competing offers costs your credit file nothing. Second, offer security where you have it, since asset-backed and invoice-backed structures usually undercut unsecured pricing. Third, connect open banking data if you can: verified account data gives lenders certainty, and what open banking shows a lender is usually a stronger case than a folder of PDFs makes for the same business.

Frequently asked questions

What is a good interest rate on a UK business loan in 2026? For an established SME with 2+ years of trading and consistent revenue, unsecured term loan offers in the 8% to 15% APR range are competitive. Newer businesses or those in higher-risk sectors typically see 15% to 30%. Below 8% unsecured is rare outside the strongest credit profiles; secured lending and asset finance regularly price lower because the lender holds security.
Are business finance rates fixed or variable? Most alternative-lender term loans and merchant cash advances are effectively fixed: the total repayment is agreed up front. Credit lines charge a rate on the drawn balance which the lender can revise at review. Some larger secured facilities track the Bank of England base rate. Always check which type you are being offered, since a variable rate quoted today is not a promise about next year.
Why is a merchant cash advance more expensive than a term loan? Because the lender takes repayment risk that flexes with your trade: a quiet month means smaller collections, and the lender waits. A factor rate of 1.25 buys you the certainty that repayments can never outrun revenue. Whether that is worth the premium depends on how volatile your takings are; for steady businesses a term loan is usually cheaper, which is exactly the comparison a multi-lender application shows you.
Does checking my rate affect my credit score? Not through Fundably. Matching uses a soft credit check, which is not visible to other lenders and does not affect your score. A hard search only happens if you proceed with a specific lender's formal offer. This is what makes comparing offers across the panel free in credit-file terms.
