You probably hold an overdraft because it’s convenient. It sits alongside your current account, kicks in the moment the balance dips below zero, and asks nothing of you once it’s set up.
You’re fine on it for the odd quiet week. We rate it a poor fit the moment your cash flow leans on it every month, because cheaper, more committed products are built for exactly that.
Why Businesses Look Beyond the Overdraft
You should watch the demand clause first. Overdraft limits are repayable on demand, which is the polite way of saying the bank can pull the rug with very little notice — often when your cash flow is already under strain.
That fragility costs you, too. Unauthorised fees are punishing, and the headline rate on an authorised overdraft, typically 15–30% EAR, is rarely competitive with a product designed for working capital.
The market has moved under you. SME overdraft lending has fallen more than 80% since 2000, from £18bn to £2.7bn, and overdrafts now make up just 5% of SME lending, down from 31% in 1998. The bank may withdraw yours whether you like it or not.
You gain most from switching if you run near the limit every month, lean on the facility to cover payroll or supplier runs, or have been told the limit is coming down. If that’s you, an alternative almost always pays.
Revolving Credit Facilities
You get the closest structural cousin to an overdraft, and a far better-behaved one. You draw what you need, repay it, and draw again without filling in another form, paying interest only on the drawn balance.
Bank rates land at 6–12% annualised for established businesses, which almost always beats the overdraft it replaces; specialist lenders sit at 12–25% for younger firms. We rate it the overdraft replacement of choice for most businesses. See our revolving credit facilities guide.
Invoice Finance
You should look here if the gap in your account is really a gap in customer payment terms. Invoice finance treats the cause, advancing 70–90% of your unpaid invoices, usually within 24 hours, and the facility grows as your turnover does.
Cost runs to a service fee of 0.5–3% of the turnover financed, plus a discount charge on what you draw. It suits B2B businesses with creditworthy customers on 30–90 day terms, not retail or project billing. See our working capital finance guide.
Business Lines of Credit
You can reach a fintech line of credit faster than a bank facility. Providers like iwoca and Tide will write a line for a business with as little as six months’ trading, with a decision back in a day or two.
The rates sit above a bank’s, but they decide quickly and lend on your cash flow. We rate it a stepping stone for a business that has outgrown its overdraft but can’t yet reach a bank facility. See our business lines of credit guide.
Merchant Cash Advances
You repay a merchant cash advance as a slice of daily card takings, with no fixed schedule — a quiet January repays less, a busy December more. It hands you a lump sum against future card sales.
The price is quoted as a factor rate, not an APR, which flatters it: at 1.25 you repay £25,000 for every £20,000 advanced, an effective 25–70% APR. We rate it the working-capital option of last resort for card-heavy firms, not a cheap overdraft swap.
Trade Finance
You should treat trade finance as a different tool, not a like-for-like overdraft swap. It funds a specific transaction — an import order, a confirmed contract — rather than a general gap in your cash flow.
If you import and pay a supplier 90 to 120 days before the goods sell, a letter of credit or import facility fits where an overdraft never did. We rate it essential for cross-border trade and irrelevant for a simple cash-timing gap. See our trade finance guide.
How to Choose
You should start with the shape of the gap, not the product. A recurring, general gap points to a revolving facility or a fintech line; a gap caused by slow B2B payment points to invoice finance.
You should match the rest the same way. Card-takings businesses that have run out of options look at an MCA; importers look at trade finance. We find owners overpay by reaching for whatever the bank offers rather than the product that fits the gap.
Then price every option against your overdraft EAR on a like-for-like basis. A committed revolving facility at 9% beats a 25% overdraft you can lose at a month’s notice. Cheapest on the headline is not always cheapest in total.
Overdraft Alternatives FAQs
What is the cheapest alternative to a business overdraft?
For most established businesses, a committed revolving credit facility at 6–12% is the cheapest like-for-like swap, because you pay interest only on what you draw. For a B2B business waiting on invoices, invoice finance at 1–4% of turnover can be cheaper still.
Can I get an overdraft alternative with thin trading history or bad credit?
Often, yes. Fintech lenders such as iwoca lend from six months’ trading on your cash flow instead of filed accounts, and merchant cash advance providers consider adverse credit. You pay a higher rate for that flexibility, so use it as a stepping stone.
How fast can an overdraft alternative be arranged?
Fintech revolving lines and merchant cash advances can fund within 24 to 48 hours using Open Banking data. Invoice finance takes a little longer to set up but then releases cash against each invoice within a day. Bank facilities are slower.
Will an overdraft alternative need a personal guarantee?
Usually, yes. Most working capital products for a limited company are backed by a director’s personal guarantee, which puts your own assets behind the facility. Read it carefully, because it is the clause that turns a business debt into a personal one.
Is a revolving credit facility really better than an overdraft?
For a business that consistently needs headroom, yes. A committed facility has a fixed term the bank cannot pull on demand, usually a lower rate, and interest only on the drawn balance. An overdraft wins only as an occasional buffer with a strong bank relationship.
Methodology and Disclosure
How we compared overdraft alternatives
Scope. We compared the main alternatives to a business overdraft on cost, speed, eligibility and how each behaves, using provider documentation and the dedicated guides linked above rather than aggregator marketing.
Data sources. Rates and fees were checked against provider pricing and the Bank of England base rate (3.75% as of June 2026). Cost figures are typical ranges, not quotes.
Update cadence. We re-verify these figures when the base rate moves or a provider changes pricing. The verification date reflects the most recent review. Some links on this page are affiliate links; see our editorial policy.
Regulatory note. This page is editorial content, not regulated financial advice. Most working capital lending to limited companies is unregulated commercial finance, so Financial Ombudsman and FSCS protections may not apply. Compare offers directly with providers before you apply.
