The best unsecured business loan lenders in the UK

If your business needs funding but you don’t want to secure borrowing against property, equipment or other assets, an unsecured business loan could be the right option. With an unsecured loan, lenders assess your business based on its financial performance, trading history and credit profile rather than asking for collateral. This often makes the application process quicker and simpler than a secured loan. However, unsecured loans can vary significantly in cost. Some high street banks offer rates starting from around 7% APR, while specialist lenders may charge up to 99%+. The best option for your business depends on factors such as your credit history, how long you have been trading, how much you want to borrow and how quickly you need access to funds. At Capitalise, we help businesses compare options from more than 130 lenders, making it easier to find the right solution without applying blindly.

What is an unsecured business loan?

An unsecured business loan is a lump sum you borrow and repay in fixed monthly instalments over an agreed term. Unlike a secured loan, you do not need to offer business or personal assets as security. This makes unsecured finance more accessible for many businesses and can speed up the approval process. Most lenders will still require a personal guarantee from at least one company director. A personal guarantee means that if the business cannot repay the loan, the guarantor becomes personally responsible for the outstanding debt. 

What can you use an unsecured business loan for?

One of the biggest advantages of an unsecured business loan is flexibility of use. Businesses commonly use unsecured loans for a variety of reasons, such as to improve cash flow, purchase stock, recruit employees, invest in equipment, cover tax liabilities, renovate premises or fund growth initiatives such as marketing campaigns. Lenders will usually ask how you plan to use the funds during the application process, but in most cases they do not place restrictions on how the money is spent once the loan is approved, as long as it is for business purposes.

Unsecured business loan lenders compared: high street banks

High street banks offer the most competitive rates, but they are also the most selective. You will typically need a good credit history, several years of filed accounts, a strong annual turnover and, in many cases, an existing relationship with the bank. If you meet those requirements, a bank loan is likely to be your cheapest funding option. However, approval and funding can take longer than with alternative lenders. If you do not meet a bank's criteria, or need access to funds more quickly, an alternative lender may be a better fit.

Unsecured business loan lenders compared: alternative and fintech lenders

If your business does not meet a bank's criteria or you need funding quickly, alternative lenders can provide a valuable option. Many fintech lenders use Open Banking data and automated assessments to make faster decisions. While this can improve accessibility, it usually comes with higher borrowing costs. Here’s a comparison of some of the most common unsecured business loan lenders:

What does an unsecured business loan actually cost?

The cost of borrowing depends on your business profile and the lender's assessment of risk. As a rough guide, here is what different types of businesses tend to pay:

Business profile

Typical rate range

Established limited company, strong credit, 2 or more years trading and high turnover

7 to 12% APR

Solid businesses with a medium risk credit score or under 2 years trading

12 to 30% APR

Short term specialist finance 

30 to 99%+ APR

When comparing lenders, it is important not to focus solely on the interest rate. Many lenders charge arrangement or completion fees. While most high street banks do not charge these fees, some alternative lenders do. Depending on the loan size, these costs can add thousands of pounds to the total amount repaid. You should also review any early repayment charges. Some lenders allow you to repay early without penalty, while others charge additional interest or fees if you settle the loan before the agreed term ends.

What do lenders look at when they assess you?

Understanding what lenders are looking for makes the whole process less daunting. Most lenders are assessing broadly the same things.

  • Your business credit score is one of the biggest factors. It shows lenders how reliably your business has met its financial obligations, and a strong score can meaningfully improve the rate you are offered. You can check your business credit score for free through Capitalise before you apply, so you know exactly where you stand.

  • Trading history matters to every lender. Most want at least 12 months. High street banks and Funding Circle typically want two or more years of filed accounts. If your business is younger than that, you are not out of options, but your pool of willing lenders will be smaller.

  • Revenue and cash flow tell lenders whether the repayments are realistically manageable. A lender considering a £120,000 loan over two years is thinking about whether your business can comfortably absorb around £5,000 a month on top of its existing costs. The stronger and more consistent your income, the more comfortable they will be.

  • Your personal credit history comes into play for most unsecured loans, particularly where a personal guarantee is involved. CCJs, defaults or missed payments in your personal history are likely to come up and may affect the terms you are offered.

  • Your sector also plays a role. Hospitality, construction and retail are typically viewed as higher risk, which can push rates up or narrow your options with certain lenders. It is not a dealbreaker, but it is worth being aware of.

Who can get an unsecured business loan?

While criteria does vary, most mainstream unsecured lenders are looking for broadly the same things:

  • A UK registered business that is actively trading

  • At least 6 to 12 months of trading history, or longer 

  • A business bank account showing regular revenue

  • A credit profile that is strong or at least not high risk

  • At least one director willing to sign a personal guarantee

Sole traders can still access unsecured business finance through many lenders, although some providers have changed their lending criteria in recent years. If your business has experienced credit difficulties, funding may still be available. Several alternative lenders assess applications individually rather than relying on strict automated credit rules. While borrowing costs may be higher, approval is often still possible.

How to compare lenders without affecting your credit score

When comparing business loan options, it is worth understanding how lenders assess applications. Most formal loan applications involve a hard credit search, which is recorded on your credit file. If you apply to several lenders individually, multiple hard searches can appear on your record within a short period. A good approach is to use a platform that matches your business with suitable lenders through a soft search. At Capitalise, one application allows you to compare options from more than 130 lenders without impacting your credit score. Our funding specialists help you understand the true cost of each offer so you can compare lenders based on total borrowing costs rather than headline rates alone. You can also use our business loan calculator to model repayments before you start.
