How to Choose a Business Loan: UK Decision Framework

Step 1: Match the Right Loan Type to Your Purpose

The purpose of the loan determines the right loan product. We see this mistake constantly: businesses applying for a term loan when a revolving facility fits the problem better, or missing invoice finance entirely.

Growth capital — hiring, new premises, expanding into a new market. Use a term loan with a fixed repayment schedule. The repayment matches a known cost, and the structure forces discipline on how the capital is deployed.

Equipment or asset purchase — machinery, vehicles, technology. Consider asset finance before a term loan. Asset finance uses the equipment itself as security, typically offers lower rates than unsecured lending, and keeps your working capital line free.

Cash flow gap — covering payroll during a slow period, bridging a payment delay, managing seasonal demand. Use a revolving credit facility rather than a term loan. You draw what you need, repay when cash arrives, and only pay interest on the outstanding balance.

Taking a term loan to solve a short-term cash flow problem means paying interest on the full amount for the entire term, even when you don’t need it all. We find revolving facilities are consistently misunderstood as a more complex or expensive option — they’re usually neither.

One-off shortfall with a defined return date — waiting on a large invoice, covering a purchase before a confirmed order pays out. Invoice financing may serve you better than a loan. The lender advances cash against the invoice; you repay when your customer pays.

If the purpose is unclear, that’s a warning sign. Lenders will ask, and a vague answer — “general working capital”, “to grow the business” — is the fastest route to a decline or an unfavourable rate. Define the specific use case before you apply anywhere.

Step 2: Establish Your Eligibility Position

Before you shortlist lenders, know where we see the four criteria that gate most loan applications. We reviewed eligibility pages across all major lender categories — these are the breakpoints that matter in practice.

Trading history

Trading age is the most commonly underweighted criterion. We see businesses skip this check more than any other. The practical breakpoints:

Under 6 months: British Business Bank Start-Up Loans only (up to £25,000 at 6% fixed, no personal guarantee). No commercial lender operates here.

6–12 months: iwoca is the primary commercial option. Rates reflect the shorter track record.

12–24 months: Funding Circle and some specialist lenders. Banks are unlikely to approve at this stage.

24 months or more: Full market access — banks, specialist lenders, and government schemes all become available options.

Don’t waste a hard credit search applying to a lender who won’t approve you at your current trading age. It’s the most avoidable mistake in a loan application.

Revenue and affordability

Lenders assess whether you can service the debt from trading income. The key variable is debt service coverage — whether your monthly profit can cover the monthly repayment.

A rough check: if your monthly repayment would exceed 30–40% of average monthly net profit, most lenders will push back.

Funding Circle requires a minimum annual revenue — confirm the current figure on their eligibility page before applying. Banks want to see this in filed accounts. For iwoca, three months of bank statements is usually sufficient.

Credit profile

Both your business and personal credit scores matter. Banks rely heavily on formal scores; specialist lenders like iwoca and Capify weight trading performance more heavily.

If you’ve a CCJ or missed payments, a bank decline is likely — but iwoca and specialist lenders may still approve at a higher rate. We recommend checking both credit files before applying anywhere — errors are common and can be corrected before they cause a decline.

Business structure

Funding Circle lends to limited companies and LLPs only — it stopped accepting sole trader applications in February 2026. Banks will lend to sole traders but with stricter documentation requirements and lower limits.

If you operate as a sole trader and need more than £25,000, your options narrow significantly. Consider whether a limited company structure serves your borrowing needs before applying.

Step 3: Choose the Right Lender Type

Once you know your purpose and eligibility position, you can match to a lender category. The four main categories have genuinely different cost and access profiles.

High-street banks

Best for: Established limited companies (24 months or more) with a clean credit history and an existing banking relationship.

Trade-off: Cheapest rates in the market for qualifying businesses, but the slowest process — two to three weeks typical — and the narrowest eligibility criteria.

If your business qualifies, a bank loan is almost certainly the lowest-cost option. That’s the deal: cheapest rate, longest wait, strictest gate.

Approaching a bank with no existing relationship is slower and unlikely to improve your rate.

Practical step: Apply to your existing bank first. Use a specialist lender as a backstop if you meet bank criteria — not as a starting point.

Specialist online lenders

Best for: Businesses that qualify for traditional lending but need a faster decision, or businesses between 12–24 months trading that a bank would decline.

Trade-off: Faster decisions (same day to 24 hours), broader eligibility, but higher rates than banks. Funding Circle from 6.9% APR is the lowest in this category; iwoca’s representative APR is 49%, reflecting the far wider access it provides.

That rate gap is significant. We find this category handles the 12–24 month trading window that banks routinely decline — and for that group, the higher rate is the price of access.

Practical step: If you’ve been trading 12–24 months as a limited company, Funding Circle is usually the best-priced option available. If you need a decision today, iwoca can fund same-day.

Government-backed schemes

Best for: Pre-revenue and early-stage businesses under three years old that need up to £25,000.

Trade-off: Cheapest rate available — 6% fixed APR — but capped at £25,000 per applicant and takes two to four weeks to fund. The application includes business planning support and mentor assignment, which extends the timeline but adds genuine value for early-stage operators.

Practical step: If your business is under three years old and your need is £25,000 or less, we’d always start with the British Business Bank before any commercial lender. The rate differential is too significant to ignore.

Merchant cash advance providers

Best for: Businesses with high card revenue (hospitality, retail, e-commerce) that can’t qualify for traditional lending, or whose revenue pattern makes fixed repayments unworkable.

Trade-off: MCAs use a factor rate rather than an APR, which makes cost comparison with loans genuinely difficult. In most scenarios, an MCA is more expensive than an equivalent loan on a total-cost basis. If you qualify for a loan, use one.

Practical step: Use an MCA only if you’ve been declined by Funding Circle and iwoca, or if the repayment flexibility of an MCA solves a genuine cash flow problem that a fixed-repayment loan wouldn’t.

Step 4: Understand the Total Loan Cost Before You Apply

The headline rate is the least useful number for comparing loans. We always calculate the total cost of borrowing — not the monthly repayment — and we recommend you do the same.

How we calculate it: take the loan amount; multiply by the annual rate over the number of years; add the arrangement fee (typically 1–3% from the lender); add broker fees if using an intermediary (typically 1–2% of the loan amount, per Funding Agent).

Also check for early repayment charges. We’ve seen borrowers choose a lower rate with an ERC end up paying more than a higher-rate product without one — because they repaid early. The ERC is the catch.

Example: a £50,000 loan at 9% APR over 3 years costs approximately £7,200 in interest. Add a 2% arrangement fee (£1,000) and the total cost is around £8,200 — 16.4% of the principal.

Compare that figure against what the loan is expected to generate or save. Monthly repayment isn’t the right comparison point.

Personal guarantee risk: Most lenders require a personal guarantee from the director. Your personal assets — home, savings — are at risk if the business defaults. The British Business Bank Start-Up Loans scheme doesn’t require one; every other mainstream lender does.

Business Loan Application Checklist

Documents to have ready: last two to three years of business bank statements (or all available if under two years); most recent filed accounts or management accounts; business and personal tax returns; proof of ID for all directors; details of any existing borrowing or credit facilities.

Questions to answer before applying: what is the loan for, and what will it generate or save? What is your trading age? Have you checked your business and personal credit reports? Does your business structure match the lender’s eligibility criteria?

Use a soft search first: Both iwoca and Funding Circle offer indicative loan terms via a soft credit check that doesn’t appear on your file. We recommend always using this before a full application.

Banks run a hard search at application stage — every time. Three bank declines means three hard searches sitting on your file when you finally apply to a specialist lender.

Your Business Loan Shortlist

Applying this framework, your shortlist should fall into one of four positions:

Pre-revenue or under 6 months trading: British Business Bank only. No commercial lender operates here.

6–12 months trading, limited company: iwoca is your primary commercial option. Funding Circle requires at least 12 months — don’t apply there yet.

12–24 months trading, limited company: Funding Circle if you can wait 24 hours and want the lower rate; iwoca if you need a decision today.

24 months or more, existing bank relationship, clean credit: your existing bank first; Funding Circle as backstop if the bank declines or prices uncompetitively.

High card revenue, flexible repayment essential: MCA provider (Capify) — but only after confirming you can’t qualify for an iwoca Flexi-Loan, which is more transparent on cost.

We built this framework from reviewing lender eligibility criteria and application outcomes across the UK business loan market. The categories hold for the vast majority of business profiles — edge cases are those with complex structures, overseas operations, or sector-specific lending restrictions.
