Meanwhile, the awareness of alternative forms of finance saw significant growth across that same period.

Lumpy cash flow 

Busleus Business Loans can help to even out seasonal peaks and troughs in your cycle. For example, a store in a seaside resort is likely to experience a surge in trade through the summer months, but a drop in revenue during winter. Nucleus Business Loans can help you through those quieter periods

Long payment terms

Are you tired of waiting for your customers to pay? You can tackle long payment terms with a Nucleus Business Loan, which will provide the financial support you need during those periods where you’re waiting to receive money owed to you for the goods or services you provide

Fulfil expansion plans

By financing your cash flow, you can achieve your dreams of hiring new staff, growing your enterprise or taking on bigger projects. It can be used for the development of businesses in all kinds of sectors and, as long as you spend the funding on your company, we place no restrictions on how it’s used


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.

A Nucleus Business Loan can offer the solution to a wide range of everyday business challenges. Here at Nucleus, we wouldn’t dream of telling you how to spend the money – it’s up to you how you run your company.

New premises

Are you looking to extend your existing space, move to another location or open another store? Nucleus Business Loans could help you do just that

Unexpected bills

If unforeseen circumstances crop up and you’re due to take a financial hit, a Nucleus Business Loan can help to soften the blow

Management buyout

If you’re looking to make a significant move, you may require additional funds to help you achieve your aim

Hiring new staff

If business is booming and you need to take on new employees, our Nucleus Business Loans can help you bring in extra bodies.


Nucleus Business Loans can also be used for staff training, purchasing new stock or equipment and revamping your marketing strategy.


Our Nucleus Business Loans start from £10,000. However, if you need to borrow less than that, we have other products which may be more suited to your situation.

Nucleus 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. Nucleus Business Loans 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.

Nucleus Business Loans are a great choice for any sized business. The benefits include:

  • They are unsecured which means they are 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.
  •  repayments for the first 12 months of the loan.
  • They help you get through tougher times – most businesses will experience ebbs and flows as they grow. Nucleus Business Loans can help you get through slower periods.

As the name suggests, 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.

Nucleus Business Loans, on the other hand, are suited to any business with a healthy cash flow. It’s an unsecured form of finance and so a result, interest rates tend to be higher.

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

We know that if you’re experiencing cash flow problems, you’ll want to get the funds through as soon as possible, so your business doesn’t grind to a halt.

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

To qualify for a Nucleus Business Loan, you need to be trading for at least 12 months.

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 repaying on time or even ahead of schedule.

If you’ve 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.
