Business loan rates in September 2026 range from 6.0% APR for secured property-backed business loans to 20%+ for unsecured high-risk business lending. The single most significant factor in business loan pricing is security: a loan secured against commercial or residential property accesses a fundamentally different rate band than an unsecured facility. The second most important factor is trading history and business credit profile. A business with 5+ years trading and property security can access rates comparable to commercial mortgage rates. A start-up business without security faces rates 3–4× higher.

What determines your rate
Security — the biggest rate driver
A secured business loan (property as collateral) accesses fundamentally lower rates than an unsecured facility. The security reduces the lender's loss-given-default risk — if the business defaults, the lender can recover from the property. On the same business profile and trading history, a secured loan at 7.5% compares with an unsecured loan at 12%–15%. The rate saving over 5 years on a £250,000 loan is approximately £30,000–£47,000. The trade-off is the risk to the secured property — typically the director's business premises or home. DBF always models the secured vs unsecured cost comparison and ensures clients understand the security risk before proceeding.
Trading history requirements
Most mainstream lenders require 2+ years of filed accounts. Businesses under 2 years face a narrower specialist lender panel at higher rates. Some fintech lenders (Iwoca, Tide) consider businesses from 6 months trading using open banking data and management accounts in lieu of filed accounts. For start-ups with no trading history, the business loan market is very thin — consider whether alternative structures (asset finance, invoice finance, or director personal borrowing) are more appropriate.
Director personal guarantee — what it means
Unsecured business loans almost universally require a director personal guarantee (PG). The PG makes the director personally liable for the loan if the business defaults. A PG is not the same as a legal charge on property — it is a personal obligation, not a secured interest. However, if the business defaults and the director cannot pay under the PG, the lender can pursue the director's personal assets including their home. DBF advises on the PG risk relative to the business loan size and the business's financial stability.
Loan purpose and exit — lender assessment
Business loan lenders assess the purpose of the loan and the repayment source. Productive loans (equipment purchase, stock, business acquisition) with clear repayment from business cash generation are viewed favourably. Working capital loans (cash flow smoothing) are also common. Refinancing of existing debt is assessed on whether the new structure is more sustainable than the existing one. Speculative or unclear purposes attract higher rates or declines. DBF advises on how to present the loan purpose most effectively to lenders.

Frequently asked questions
What are business loan rates in September 2026?
Secured business loans (property as security): 6.0%–9.5% APR. Unsecured business loans (strong covenant, 5+ years trading): 9.5%–13% APR. Unsecured (2–5 years trading): 12%–18% APR. Start-up or adverse credit: 18%–25%+. The rate difference between secured and unsecured is the most significant variable — up to 10% APR on the same business profile.
Do I need security for a business loan?
No — unsecured business loans are available for established businesses with strong financials and a director guarantee. However, secured loans (property charge) access significantly lower rates (6%–9.5% vs 9.5%–18% unsecured). If property security is available and the rate saving justifies the security risk, a secured loan is usually cheaper.
What is a director personal guarantee?
A personal guarantee makes the director personally liable for the business loan if the company defaults. It is not a secured interest on property (unless the guarantee is backed by a legal charge) — it is a personal obligation. If the business defaults, the lender can pursue the director personally. Directors should understand and take independent advice before providing personal guarantees.
How long does a business loan take to arrange?
Secured business loans (property valuation required): 3–6 weeks. Unsecured business loans (no valuation): 1–3 weeks. Fintech unsecured loans (open banking assessment): 24–72 hours. DBF advises on the fastest route for each business's profile and timeline.
Can I get a business loan as a start-up?
Yes — but the panel is restricted. Government-backed schemes (Recovery Loan Scheme where available), specialist start-up lenders, and some fintech lenders consider businesses under 2 years old. Rates are higher (18%–25%+) and amounts lower (typically up to £50,000). Director personal credit and any director track record are key assessment factors. DBF advises on the most appropriate route for each start-up profile.
