What Interest Rate Will I Pay On A Small Business Loan?

Getting your head around business loan rates

Small business loan interest rates in the UK can feel frustratingly vague at first, because there is no single market average you can rely on. What you pay is usually shaped by the type of loan, how long you want to repay it, whether the borrowing is secured, and how strong your application looks to the lender. In practice, two businesses asking for the same amount can end up with very different APRs, even in the same week. Understanding APR isn’t just about percentages - it’s about knowing what you’ll pay in real terms, and whether the repayments remain manageable if trading has a slower month.

It also helps to separate headline rates you see in adverts from the rate you are actually offered after checks. Some lenders promote rates starting around the high single digits, while typical unsecured business loans can start around 6% and run to 15% or more depending on risk. Government-backed Start Up Loans add another useful benchmark, but even those terms can change, so it pays to check the live application page before you plan your numbers.

A useful rule of thumb: expect a rate band, not a single “standard” rate.

Is this aimed at you?

This guide is for UK consumers who run, or plan to start, a small business and want plain-English clarity on what interest rate they might pay. It’s especially relevant if you’re comparing an unsecured business loan, a secured option (such as borrowing against assets), or a Start Up Loan and you want to understand how lenders set pricing. If you’re trying to work out affordability before applying, or you’ve seen a low “from” rate and want to know what it really means, you’re in the right place.

The rate you pay: what it actually means

The interest rate on a small business loan is the price of borrowing, usually expressed as an APR (Annual Percentage Rate). APR is designed to help you compare products because it reflects the yearly cost of borrowing, and can include certain fees where applicable. However, not every lender structures costs identically, so you still need to read the offer carefully.

In the UK, you’ll often find that unsecured business loan rates can begin around 6% for stronger applications and rise to 15% or more where the lender sees higher risk. Some lenders advertise representative starting rates around 6.9% for business loans, but that does not mean most applicants will receive that figure. High-street banks may offer fixed-rate borrowing up to specific limits, yet the actual rate is normally confirmed only after approval.

Start Up Loans are worth calling out because they are unsecured personal loans used for business purposes, rather than a standard commercial business loan. The government Start Up Loan scheme shows a fixed rate of 7.5% per year from 6 April 2026, while other official guidance has historically referenced 6%, so checking the live terms is essential.

How lenders arrive at your rate

Most lenders price business borrowing by combining three things: the product’s baseline pricing, the risk they believe they are taking, and the structure of the deal. The biggest levers tend to be security, affordability, and credit strength.

If you offer security (for example, borrowing against a business asset such as property or vehicles), the lender’s potential loss is reduced, and secured business loans often come with lower rates than unsecured alternatives. If you borrow without security, the lender may charge more because recovery options are limited.

Your credit profile and existing debt levels also matter. Lenders commonly review personal and business credit data, your recent repayment history, and how stretched your finances already are. Even with the same turnover, a business with fewer existing commitments may be offered better pricing than one already servicing multiple agreements.

Finally, term length affects cost. Longer terms can reduce monthly repayments but may increase the total interest paid over time. Some lenders offer terms from months to several years, and the rate you receive can move in line with the repayment period.

Why rates vary so much in the UK

Interest rates vary because small business lending is not a one-size-fits-all market. A lender is effectively answering one question: how likely is it that they will be repaid, on time, in full? The type of business, trading history, sector volatility, cashflow consistency, and available collateral all feed into that judgement.

That is why it can be misleading to search for “the average UK small business loan rate”. In reality, you should expect a range based on your circumstances and the loan structure. A competitive headline rate may be available for a strong application, but your own offer could be higher once the lender completes checks.

Government-backed products can provide a helpful reference point, especially for newer businesses that may not qualify for mainstream lending. However, even these schemes can change pricing over time. If you are building a business plan around a specific APR, it’s wise to confirm the current figure on the live scheme page before you commit to forecasts.

Pros and cons of focusing on interest rate

Red flags and fine print to keep in mind

A low rate is only valuable if the full agreement fits your business. Start by checking whether the rate is fixed or variable. Fixed rates can be easier to budget for, while variable pricing may change your monthly cost over time. Next, look at the total cost of credit, not just the APR, because the term length can materially alter how much interest you pay overall.

Be careful with “from” rates. They can be genuine, but they are usually aimed at the strongest applications. If your credit file has errors, correcting them before you apply can sometimes improve eligibility and pricing. Also pay attention to security and personal guarantees. Adding security or guarantees may unlock better pricing, but it increases what you could lose if the business cannot repay.

Finally, if you are considering a Start Up Loan, remember it is a personal loan for business purposes, with fixed scheme pricing and specific eligibility rules. Because published guidance can lag behind policy updates, always check the live terms before relying on a quoted APR.

Alternatives to a standard small business loan

1. Government Start Up Loan (fixed-rate scheme for eligible founders)

2. Secured business loan (borrowing backed by assets, potentially lower rate)

3. Business overdraft (flexible, but often costlier if used long-term)

4. Business credit card (useful for short-term cashflow, watch the interest rate)

5. Asset finance (spreading the cost of equipment or vehicles)

6. Invoice finance (unlocking cash tied up in unpaid invoices)

FAQs

What interest rate is “normal” for a UK small business loan?

There isn’t one normal rate. Unsecured business loans can start around 6% for strong applications and rise to 15% or more depending on risk, term, and affordability.

Does a secured business loan usually have a lower rate?

Often, yes. When you provide security, the lender’s risk can be lower, which may lead to a lower interest rate than an unsecured loan. The trade-off is that assets may be at risk if you miss repayments.

Are Start Up Loans business loans?

They are typically structured as unsecured personal loans used for business purposes, rather than a standard commercial business loan. That can affect eligibility, assessment, and the way the borrowing is documented.

What is the Start Up Loan interest rate?

The government application page states a fixed 7.5% per year from 6 April 2026. Other guidance has previously referenced 6%, so you should rely on the live application terms when budgeting.

Can I improve the rate I’m offered?

Potentially. Improving credit file accuracy, reducing existing debt where possible, choosing an appropriate term, and considering security (if suitable) can all influence pricing and eligibility.
