UK SME lending has diversified significantly since 2015. Alternative lenders including Funding Circle, iwoca, Capital on Tap, and MarketFinance offer faster decisions than high-street banks and integrate with accounting software to assess creditworthiness via live financial data. FCA-authorised lenders must comply with the CONC sourcebook for sole trader lending; the Consumer Credit Act 1974 protects small business borrowers in certain circumstances. This guide maps the market and the regulatory framework.

UK SME lending has been transformed by the entry of FCA-authorised alternative lenders that use Open Banking and accounting software data to make faster, more data-driven credit decisions than traditional bank underwriting. A business applying for a loan from Funding Circle or iwoca can connect its Xero or QuickBooks account and receive a decision based on live revenue, cash flow, and expense data rather than a six-month-old set of management accounts. For businesses that need capital quickly - to fund a large order, bridge a payment delay, or manage a seasonal cashflow trough - this speed advantage is often decisive. Understanding the regulatory framework that governs UK SME lending, the different loan structures available, and the cost comparison methodology is essential for any finance director evaluating borrowing options.
The Regulatory Framework: FCA CONC and the Consumer Credit Act
UK business lending regulation applies differently depending on the borrower's legal structure. Loans to limited companies are largely unregulated by the Consumer Credit Act 1974 - limited companies are not consumers and do not benefit from the Act's protections (right to a cooling-off period, regulated agreement requirements, Section 75 liability). Loans to sole traders and small partnerships (fewer than four partners) fall within the Act's scope where the loan amount is below £25,000, giving these borrowers the full suite of consumer credit protections.
The FCA's CONC sourcebook applies to all consumer credit lending, including lending to sole traders below the threshold. CONC requires lenders to conduct creditworthiness assessments, provide pre-contractual information in a standardised format, and treat customers in financial difficulty fairly. Sole traders borrowing above £25,000 or limited companies at any amount operate outside the Consumer Credit Act framework, though the FCA's principles for business conduct (including treating customers fairly) continue to apply to FCA-authorised lenders.
All business lenders operating in the UK must be FCA-authorised for consumer credit (if lending to sole traders) or hold the relevant FCA permissions for their lending activities. The FCA register confirms the permissions held by any lender. Businesses should verify FCA authorisation before entering into any loan agreement; unregulated loan intermediaries and introducers have been a source of mis-selling risk in the SME market, particularly for asset finance and merchant cash advance products.
Accounting Software Integration and Open Banking Underwriting
The most significant operational innovation in UK SME lending is the use of accounting software and Open Banking data in credit assessment. Funding Circle, iwoca, and MarketFinance all offer accounting software connections that allow the lender to access live revenue, expenses, cash flow, and debtor data from the borrower's Xero, QuickBooks, or Sage account. This replaces the traditional requirement for two years of filed accounts and six months of bank statements with a real-time view of the business's financial position, enabling faster decisions - sometimes within 24 hours rather than the weeks required by traditional bank underwriting.
For businesses with strong accounting records maintained on a recognised platform, this data-driven underwriting model is advantageous: the lender can see exactly what the business is earning, how it manages its cash, and what its current liability position is. For businesses with poor bookkeeping, gaps in their accounting records, or large unexplained transactions, the same data access works against them. The practical implication is that businesses that maintain clean, up-to-date accounting records throughout the year - not just at year-end for accountancy purposes - are better positioned for faster, lower-cost access to business credit.

Loan Structures: Term Loans, Revolving Credit, and Invoice Finance
UK business lending divides into three main structures. Term loans provide a lump sum repaid over a fixed period with scheduled repayments - appropriate for capital investment, equipment purchase, or expansion projects with a defined payback period. Revolving credit facilities (including the credit line products offered by iwoca and the Capital on Tap revolving credit) allow the business to draw, repay, and redraw up to a facility limit, paying interest only on the drawn balance - appropriate for working capital management and cashflow smoothing. Invoice finance - either invoice factoring (where the lender buys the invoice and manages collections) or invoice discounting (where the lender advances against the invoice value but the business retains collection responsibility) - turns outstanding debtors into immediate cash, appropriate for businesses with long debtor payment terms and strong invoice volumes.
The FSB's lending guidance highlights that many SME owners do not fully understand the total cost of borrowing, particularly for revolving credit and invoice finance products where the cost is expressed as a daily rate, factor rate, or percentage of invoice value rather than a conventional Annual Percentage Rate (APR). The FCA's CONC sourcebook requires clear pre-contractual disclosure of the total cost of credit for consumer credit agreements; limited company borrowers are not entitled to the same standardised disclosure and must calculate total cost from the loan agreement terms. Finance directors should always calculate the effective annualised interest rate for any business loan or credit facility before signing, rather than comparing headline daily or monthly rates across different product types.
Personal Guarantees and Director Liability
The majority of UK SME lenders require a personal guarantee from one or more directors before approving a loan to a limited company. A personal guarantee makes the guaranteeing director personally liable for the loan repayment if the company fails to pay. This pierces the limited liability protection that a limited company structure normally provides and means the director's personal assets - including their home, if not protected by a spouse's beneficial interest or a declaration of trust - are at risk if the business loan defaults.
The British Business Bank's published guidance on personal guarantees advises SME borrowers to take independent legal advice before signing a personal guarantee, to negotiate limitations where possible (a cap on the guarantee amount, a time limitation, or a carve-out for matrimonial home equity), and to understand the specific trigger events that allow the lender to call the guarantee. Loan comparison software and broker platforms that present business loans without prominent disclosure of the personal guarantee requirement are a source of borrower complaints to the Financial Ombudsman Service.
FAQ
Is a sole trader protected by the Consumer Credit Act when taking a business loan?
Yes, where the loan amount is below £25,000 and the lender is FCA-authorised for consumer credit. In these circumstances, the Consumer Credit Act 1974 protections apply: the lender must provide a regulated credit agreement, the borrower has a 14-day cooling-off right, and the FCA's CONC responsible lending requirements apply. Sole traders borrowing above £25,000 or limited companies at any amount are generally outside the Consumer Credit Act framework, though FCA conduct rules continue to apply to authorised lenders.
How does iwoca's flexi-loan differ from a term loan?
iwoca's flexi-loan is a revolving credit facility: the business draws funds as needed, repays when it has surplus cash, and redraws when required - up to the approved facility limit. Interest accrues daily on the drawn balance only. A traditional term loan provides a fixed lump sum repaid on a schedule over a defined period, with interest charged on the outstanding balance. The flexi-loan structure suits businesses with variable funding needs and irregular cashflow; a term loan suits businesses with a specific capital requirement and predictable repayment capacity.
What is invoice discounting and how does it differ from factoring?
Invoice discounting advances a percentage of the invoice value (typically 80-90%) to the business immediately on invoice issuance, with the balance (minus fees) released when the customer pays. The business retains responsibility for chasing payment from its customers and the lending arrangement is typically confidential from the customer. Invoice factoring involves the lender purchasing the invoice and taking over responsibility for collections - the customer may be aware of or notified of the factoring arrangement. Factoring is simpler for businesses without a credit control function; discounting is preferred by businesses that want to maintain their own customer relationships.
What is the British Business Bank and does it lend directly to businesses?
The British Business Bank is a government-owned economic development bank that supports SME lending by providing guarantees, co-investments, and funding to accredited lenders - including Funding Circle, iwoca, and high-street banks - rather than lending directly to businesses. Its programmes (including the Growth Guarantee Scheme, which succeeded the Recovery Loan Scheme) make lending to higher-risk SMEs more accessible by guaranteeing a proportion of the lender's exposure. Businesses cannot apply to the British Business Bank directly; they access its schemes through its accredited lender partners.
Can accounting software improve a business's chances of getting a loan?
Yes. Alternative lenders that use accounting software data in their underwriting - Funding Circle, iwoca, MarketFinance - make faster and often more favourable decisions for businesses with clean, up-to-date financial records on recognised platforms. The lender's algorithm can see real-time revenue trends, cash conversion cycles, and expense patterns without waiting for filed accounts. Businesses that maintain their accounting on Xero, QuickBooks, or Sage and connect their account during the application process typically receive faster decisions and are more likely to be approved than those relying on manual bank statement submission.
