Why this decision costs more than it looks
The UK business banking market has split into two camps. High street names still hold most SME deposits, yet a growing share of sole traders and small limited companies now run everything from an app. Onboarding that once took an appointment now takes a selfie, a photo of your ID and a Companies House lookup.
That convenience hides a difference most comparison pages skip: not every "bank" is a bank. Starling and Monzo hold full UK banking licences, so eligible deposits sit under the Financial Services Compensation Scheme, currently up to £85,000 per person per institution. Tide describes itself as a business financial platform rather than a bank, and e-money firms safeguard customer funds in separate accounts instead of offering FSCS cover. Neither model is wrong, but they are not interchangeable if your balance regularly runs into five figures.
Payment rails are another factor. Any account worth opening should support Faster Payments, Bacs Direct Debits for suppliers and payroll, and Confirmation of Payee checks when you add a new payee. If you invoice overseas clients, the currency markup quietly decides whether that online business bank account is cheap or expensive.
Where UK owners usually get stuck
When the word "bank" is doing heavy lifting
A common story: a two-person design studio in Manchester moves from a high street branch to a £0 monthly fee app account because the onboarding was quicker. Six months later they are holding £40,000 ahead of a VAT bill and realise the money is safeguarded, not FSCS-protected. Nothing is lost, but the risk profile has changed. Checking the FCA register before you apply takes two minutes and settles the question.
Cash and cheques have not disappeared
Plenty of UK trades still take cash. Digital-first accounts handle it through Post Office or PayPoint deposits, and those carry a percentage fee, often with a minimum charge. A Cornwall sole trader running a seasonal holiday let will feel that far more than a London consultant who never touches notes. Cheque imaging in-app is now standard, which helps, but the deposit route still matters.
The fee that shows up in month three
Introductory periods are the oldest trick in business banking. An account marketed as £0 often becomes a monthly fee after twelve or eighteen months, and per-transfer charges on £0 plans add up fast once you are paying subcontractors weekly. Twenty pence a transfer sounds trivial until you make forty of them.
Comparing the realistic options
Monthly figures below reflect published pricing at the time of writing. Always confirm on the provider's own price page, because plan structures change.
| Provider | Monthly cost | Best for | Strengths | Watch-outs |
|---|
| Tide | £0 plan; paid plans at £12.49, £24.99 and £69.99 plus VAT | Sole traders and small limited companies | Quick app onboarding, invoicing tools, expense cards | Not a bank; around 20p per bank transfer on the £0 plan; cash deposit charges |
| Starling | £0; Business Toolkit around £7 | Owners who want a licensed bank with built-in bookkeeping | FSCS protection, no UK payment charges, Post Office cash deposits | Cash deposit fee around 0.7% with a £3 minimum; toolkit billed separately |
| Monzo Business | £0 tier plus a paid Pro plan | Solo directors and freelancers who work entirely in-app | Clear interface, tax pots, accounting integrations | Less comfortable for cash-heavy or multi-currency trade |
| Revolut Business | £0; Grow around £25; Scale around £79 | Businesses with international clients and contractor cards | Multi-currency holding, team cards, API access | Plan limits on included transfers; e-money rather than a bank licence |
| Wise Business | £0 monthly | Exporters and contractors paid in several currencies | Conversion from roughly 0.4%, local account details abroad | Not a full banking service; no overdraft facility |
| High street banks | £0 during an introductory period, then a monthly fee | Businesses needing lending, cash handling or a relationship manager | Branch access, overdrafts, invoice finance | Fees resume after the intro period; slower onboarding |
Reading that table, the cheapest looking online business bank account is rarely the cheapest in practice. A freelancer making four transfers a month pays almost nothing on a £0 plan. A café paying ten suppliers a week, depositing takings and running payroll needs to price per-transaction charges before comparing monthly fees at all.
Matching the account to how you actually trade
Sole traders with mostly card income
If money arrives by card or bank transfer and leaves by Direct Debit, a £0 plan with clean invoicing wins. Monzo's tax pots suit anyone who needs to ring-fence VAT and Self Assessment money without opening a separate savings account. A Birmingham illustrator we spoke to through a local freelancer group moved for exactly this reason, then added the paid tier once invoicing volume grew.
Limited companies with staff and suppliers
Directors need multi-user access, payment approval controls and a clean audit trail for Companies House filings. Starling's multi-director access and £0 UK payment charges make it a strong default, and the optional toolkit covers bookkeeping without a separate subscription. Where an overdraft or a lending facility is likely within two years, a high street account still does something the apps cannot.
Businesses earning in several currencies
A Birmingham importer paying European suppliers and a Manchester agency invoicing US clients have the same problem: conversion spread. Wise Business is the pragmatic choice for holding and converting currency, while Revolut Business adds card controls for staff spending abroad. Many owners run a licensed bank account for domestic Direct Debits alongside a currency account for international flows. Two accounts, one bookkeeping routine.
Opening one without losing a week
- Confirm eligibility before you start: UK-based business, valid photo ID, and director details already filed at Companies House.
- Decide your protection requirement based on the highest balance you expect to hold, not today's balance.
- Write a short must-have list: Direct Debits, number of users, accounting software link, cash deposit route, card spending abroad.
- Estimate monthly transaction volume and price the per-transfer charges against the monthly fee.
- Use the Current Account Switch Service if you are moving an existing account, and update HMRC, payroll and any recurring payees in the same week.
- Keep records from day one. Making Tax Digital requirements and company filing deadlines do not wait for a tidy bookkeeping habit.
- Review after six months. If you are paying more in transaction fees than a paid plan would cost, move up a tier rather than switching provider.
Regional support exists if you want a second opinion. The Business Support Helpline covers England, Business Gateway handles Scotland, Business Wales and Invest NI serve their own nations, and the British Business Bank publishes guidance on finance options. The FCA register confirms whether a firm is authorised, and the Financial Ombudsman Service can step in if a complaint stalls.
An online business bank account is a piece of infrastructure, not a loyalty decision. Open one that matches your transaction pattern, check how your money is protected, and revisit the pricing once your turnover changes. The right account should be almost boring to run, which is exactly the point.
