An unsecured business loan provides a lump sum of working capital without requiring property, vehicles, or other assets as security. For sole traders, this structure is often essential: self-employed individuals rarely hold commercial property or extensive business assets to pledge. The funds help bridge the gap between invoicing clients and receiving payment, cover seasonal dips in cash flow, or finance stock and materials. Loans typically suit day-to-day operational needs rather than large capital projects.
Comparing working capital lenders for sole traders goes well beyond headline interest rates. Minimum turnover thresholds and trading history requirements vary sharply between providers, and some specialist lenders now use Open Banking data rather than traditional credit scores to assess affordability. Sole traders should also check whether a lender accepts self-employed applicants at all, as some products are reserved for limited companies. Funding speed matters when cash flow is tight, with several lenders offering same-day or next-day decisions.
Important note:
Funding Agent
Published loan rangeFrom £10,000 to up to £1,000,000
Rate typeInterest from 6.8% annually
Why it is included:It is included because many business owners need to compare several finance routes before choosing where to apply.
Funding Agent can help businesses compare suitable options across a lender panel, especially when eligibility depends on turnover, sector, trading history, credit strength and available documents.
Best use case: When the borrower wants to avoid applying to one lender at a time.

Why it stands out
- Useful when a business wants to compare lender fit rather than guess which lender to apply to first.
- Can help position the application around the funding purpose, trading profile and available documents.
- Works well as a conversion route for readers who are unsure whether a direct lender will approve a larger unsecured facility.
Need to know
- Funding Agent is a broker, not a lender.
- The lender, not Funding Agent, sets the final rate, term, fees and approval decision.
- The best match may be unsecured, secured, revolving credit, invoice finance or another product depending on the case.
Expert take
Funding Agent is a useful honourable mention for business owners who want to compare lender options before submitting a full application. A larger unsecured loan is not always approved by the first lender a business finds, so understanding lender fit early can reduce wasted time and avoid unnecessary declines.

How working capital finance works for sole traders
Sole traders often face cash flow gaps between paying suppliers and receiving customer payments. Working capital finance bridges that gap, giving you funds to cover wages, stock, rent, or unexpected expenses without waiting for invoices to clear.
Unsecured business loans are the most common option. They do not require property or asset security, which suits sole traders who rent premises or own few business assets. Instead, lenders assess your trading history, bank statements, and turnover to decide how much to lend.
Revolving credit facilities work like an overdraft you can draw on when needed, repaying only what you use. Merchant cash advances let you borrow against future card transactions and repay through a percentage of daily sales, which can help seasonal sole traders.
Most lenders ask for a personal guarantee rather than physical collateral. This means you are personally liable if the business cannot repay, so it is important to understand the commitment before you sign.
Eligibility thresholds sole traders should compare across working capital lenders
Working capital lenders set different entry thresholds, and sole traders with modest turnover or short trading histories can still find options. CubeFunder accepts businesses trading for just three months with turnover from £4,000. Iwoca considers applicants from one month of trading and £5,000 turnover. SWIG Finance goes further, with no minimum turnover or trading history requirement.
At the higher end, Capify and Swishfund both look for at least £50,000 turnover, with Capify requiring six months of trading and Swishfund asking for twelve. Bizcap sets a higher bar at £144,000 turnover, though its four-month trading requirement stays relatively low.
Loan sizes vary too. SWIG Finance and Tide Bank both lend from £500. CubeFunder and Bizcap start at £5,000. Capify, Swishfund, and Funding Circle each set a £10,000 minimum.
Nearly all lenders listed here ask for a personal guarantee. Homeownership is not required, which keeps the door open for sole traders who do not own property.
How turnover-based lending helps sole traders qualify without years of trading history
Traditional banks often rely heavily on credit scores and years of filed accounts. Many working capital lenders on this page take a different approach, using turnover-based underwriting that evaluates your real-time trading performance.
Recent bank statements and monthly revenue matter more than your credit history. Iwoca and CubeFunder both use open banking to assess your business income directly, rather than relying solely on credit reference agency data. This helps sole traders who have steady income but limited formal trading history.
Open banking lets lenders view your transaction data securely, with your consent, giving them confidence in your ability to repay even if your business is young.
Factor rate pricing, used by Capify and Bizcap, works differently from traditional interest. Instead of an annual percentage rate, you agree a fixed borrowing cost upfront. Factor rates from 1.1% to 1.4% per month mean you know your total repayment from day one.
This approach rewards consistent revenue over long track records, making working capital more accessible for self-employed applicants.
Simple steps sole traders can take to strengthen a working capital application
Lenders look for clarity in your finances, and sole traders can take practical steps to improve their chances of approval.
Keep a separate business bank account, even if you are not legally required to. Lenders want to see clean transaction data that clearly shows your trading income and outgoings. Mixing personal and business spending in one account makes it harder for underwriters to assess your true revenue.
Use accounting software to track your turnover and expenses. Digital records help open banking connections pull accurate data, speeding up lender decisions.
File your self-assessment tax returns on time. Some lenders use SA302 forms or tax year overviews to verify your income, and gaps or late filings can slow down an application.
If your turnover is below £10,000, target lenders with lower minimums. SWIG Finance and Tide Bank accept borrowers needing smaller amounts from £500, while CubeFunder and Iwoca keep turnover thresholds at £4,000 and £5,000 respectively.
A personal guarantee is standard across most working capital products for sole traders, so check the terms carefully and understand your liability before committing.
