How to Choose a Business Loan: A 2026 Decision Framework

Start With the Decision, Not the Lender

You’ll choose better if you start with four things, not a lender’s advert: the purpose, how predictable your cash flow is, how fast you need the money, and what you can afford to repay.

You pick the lender last, not first.

We work in that order because the cheapest advertised rate is useless if the structure fights your cash flow, or you don’t qualify. Get the shape right, then optimise the price.

Match the Loan Type to Your Cash Flow

You match the product to how money moves through your business. A term loan suits a one-off, known cost — equipment, a fit-out — repaid in fixed instalments you can forecast.

You want a revolving facility instead when your income is lumpy or seasonal. iwoca’s Flexi-Loan lets you draw, repay, and redraw, charging interest only on what you hold — useful when a supplier bill lands before a customer pays.

A merchant cash advance fits a card-heavy trade: you repay a slice of daily takings, so a quiet week costs you less. Invoice finance fits B2B firms whose only real problem is slow payers.

Match the structure to your cash flow and half the work is done.

Compare the Total Repayable, Not Just the APR

You should compare the total amount repayable, not the headline APR — it’s the one number that survives every pricing trick. A short, scary-looking advance can cost less in cash than a cheap-looking five-year loan that drains your cash flow for years.

You should watch the factor rate on a merchant cash advance. Borrow £10,000 at a factor of 1.25 and you repay £12,500, whatever the timetable — there’s no APR until you convert it.

That advance flatters and bites by turns: repaid over a year it works out near a 50% effective APR, but cleared in six months the rate effectively doubles. The cash cost is fixed; the APR isn’t.

You should get the total repayable and the fee schedule in writing every time — we always do. If a lender won’t give you a clear figure, that’s your answer.

Secured or Unsecured: Rate vs Risk

You trade rate against risk here. A secured loan, backed by property or equipment, runs at 6-10% APR; an unsecured one costs more — 8-15% from a bank, 15-50% from an alternative lender — but risks no asset your cash flow depends on.

You get speed in return for the higher unsecured rate. Funds can land in 24-48 hours through open banking, while a secured deal takes two to six weeks for a valuation and the legal work.

There’s a catch under “unsecured”, though: most unsecured lending to a limited company still needs a personal guarantee, so your home isn’t fully off the table. We weigh that against the rate saving every time.

Fixed or Variable Rate

You should weigh rate risk before you sign. A variable loan tracks the Bank of England base rate — 3.75% in mid-2026 — plus a lender margin, so a base-rate rise lifts your repayment.

You’re safer on a fixed rate when cash flow is tight or the outlook is uncertain, because the monthly payment can’t move under you. Funding Circle, for one, lends only at fixed rates.

Certainty costs you a little; a rate shock costs you more.

Which Lender Type Fits You

You’re choosing between three camps: high-street banks, alternative lenders, and government schemes. Each wins on a different axis — price, speed, or access.

Banks offer the lowest rates, often 8-15% APR, but the slowest, most paperwork-heavy process, and they want two years of trading. You don’t need to bank with them — Barclays, NatWest, Lloyds, and HSBC all lend to non-customers.

You pay more with alternative lenders like iwoca, Funding Circle, and Capify, but they decide in hours and flex on trading history — iwoca even funds startups. We reach for them when your cash flow can’t wait or a thin file rules out a bank.

You can beat the open market with a government scheme. A Start Up Loan lends at a fixed 7.5% with no guarantor; the Growth Guarantee Scheme backs a lender 70% on facilities up to £2 million — though you stay fully liable.

The Fees That Change the Real Cost

You should price the fees beside the rate. An arrangement or completion fee, usually taken from what lands in your account, plus any broker commission, can shift the real cost more than a point of APR.

Check the early-repayment terms before you sign. iwoca and Funding Circle charge nothing to settle early, so clearing the balance when your cash flow allows saves you interest; a high-street bank often charges a penalty.

That’s how a cheap loan quietly costs you.

Picking the Right Term Length

You balance two things on term length: the monthly payment and the total interest. A shorter term costs less overall but demands more each month; a longer one eases the monthly hit and inflates the total.

Run the numbers before you commit. Borrow £50,000 at 15% APR and you’ll pay about £12,500 in interest over three years, but £21,500 over five — the same loan, £9,000 dearer for the longer breathing room.

We would borrow for the shortest term your cash flow can comfortably bear.

Check Eligibility Before You Apply

You should run a soft eligibility check before a full application. A soft search shows what you’re likely to be offered without marking your credit file; a full application leaves a hard search visible for 12 months.

You match yourself to the lender first. There’s little point applying to Funding Circle as a sole trader, or to a bank with a year’s trading — a decline still dents your credit file and teaches you nothing.

We compare on soft checks across two or three lenders, then submit one full application to the best fit. It’s the simplest way to protect your score while you shop.

Red Flags to Walk Away From

You should walk away from a few clear warning signs. Any broker asking for an upfront cash fee to “secure” a loan is a fraud marker — reputable lenders take their fee from the advance.

You should be wary of stacking. If a broker pushes a second merchant cash advance on top of a running one, the daily card deductions can strangle your cash flow and tip a solvent business over.

If a lender won’t show you the total repayable, that’s your cue to leave.
