What is an Unsecured Business Loan?

If your business needs a cash flow boost, then this could be the perfect product for you. Whether you’re looking to expand your premises or workforce, take your company to the next level or cover an unexpected bill, our Nucleus Business Loans are the ideal solution.

Nucleus Business Loans are an unsecured form of business funding that can help you push your company to greater heights. And rest assured that if you are seeking an alternative source of financial support, you’re certainly not on your own. A recent study from the British Business Bank found that the level of lending from banks to SMEs has plateaued over the past few years. Meanwhile, the awareness of alternative forms of finance saw significant growth across that same period.

If you’re looking for a cash flow loan for your small business, you’ve come to the right place. We can lend you between £10,000 and £2m repayable over three months to six years.

Our Nucleus Business Loans are unsecured, so you won’t have to put up your home or any other assets as collateral.

A recent report from the government found that 41% of SMEs felt they would not be accepted for external funding. At Nucleus, we want to help as many people as possible, and our Nucleus Business Loans are available to all those who meet the eligibility criteria. As an unsecured form of funding, you won’t have to put up your home or other assets as collateral.

With Nucleus, business loans start from as little as £10,000, however, if your business is seeking financing lower than this, there are still other loan options available.

If our business loan minimum is not suitable for your business currently but you would like to explore other options, please do not hesitate to contact us at any time on – 020 7839 1980 – to make an inquiry with one of our teams. Alternatively, you can request a call back at a time convenient to you.

Business loans are designed to help small businesses finance daily operations. An example could be a bakery needing £150,000 to purchase equipment and machinery to create its produce. A business loan would help the owner finance these supplies with the view that this will be paid back (with interest) once the produce is sold.

Nucleus Business Loans can be used by those who do not have the required assets to secure asset-based funding. Similar to a standard loan, you could also use the finance for renovating your premises, hiring staff, building a website or even paying rent or bills – the choice is yours. 

Many advantages come with a well utilised business loan, and can help businesses of all sizes in the pursuit of their goals. Most businesses will experience financial ebbs and flows as they expand, so a loan can provide both security to help during tough times, and opportunity for when you are ready to capitalise on your next opportunity.

Benefits of business loans unique to Nucleus include:

  • They are unsecured – as well as often being quicker to arrange than secured loans, Nucleus Business Loans don’t require you to put up your property or assets as collateral.
  • They are quick – Over 95% of deals are decisioned within 1 minute.

A concise breakdown of Nucleus business loan advantages can be found in our fact sheet.

Asset-based lending is secured by specific assets, while business loans have the opportunity of being unsecured. Asset-based loan amounts can change depending on the worth of the collateral whereas business loans are typically arranged as term funds with a constant payment amount.

Asset-based lending is only suitable for businesses that have assets to secure the loan against. It is a popular option for those that have the value of their property, machinery, equipment or fleet of vehicles on their balance sheet.

Business Loans, on the other hand, can be granted unsecured, and due to this tend to have a higher interest rate suiting them businesses with an established and healthy cash flow.

The maximum repayment term for a Nucleus Business Loan is six years. 

If your application for a Nucleus business loan is approved, you could have the money in your account within 24 hours.

As a lender, we understand that in the event of cash flow challenges, it is imperative that you secure funding as quickly as possible so you can capitalise on that business opportunity or avoid operation disruptions.

Our team is committed to working with you to facilitate the arrival of funds to support your business.

Unlike many other finance houses, with Nucleus there are no fees if you want to repay your business loan ahead of schedule, as long as you settle the amount in full. 

To qualify for a business loan with Nucleus, you need to have been trading for at least 12 months. If you have not yet been operating for this length of time but still need the funding, it is worth looking at our other loan options to see if something more suitable is available.

Just like a traditional loan, when you’re applying for finance for your cash flow, your credit rating will be a deciding factor in whether you get approved. However, unlike a traditional loan, Nucleus business loans focus more on your business performance than your credit history. So, you may be more likely to be approved, even if you have a bad credit rating.

If you’re a company with a poor credit history, you may even be able to boost your credit score with a business cash flow loan by paying on time or even ahead of schedule.

It is our goal to see businesses flourish and reach their objectives, both short and long term. At Nucleus, we understand that unexpected circumstances can sometimes lead to downward trends or losses in companies. As such, we always look at the bigger picture and assess businesses on an individual basis to try and get the people that need it the funding they seek.

If you have decided that a Nucleus Business Loan is not suitable for you and your business, you can check out our full range of funding solutions. We can even offer a bespoke combination of products, tailored to your needs.

If you wish to speak to an advisor, please do not hesitate to contact us at any time on – 020 7839 1980 – to make an inquiry with one of our teams. Alternatively, you can request a call back at a time convenient to you.
