Why so many UK firms now bank inside an app
Branch-free business banking stopped being the newcomer's trick a while back. Starling reports more than half a million business customers, and Tide, Mettle and Monzo have all built sizeable bases among sole traders and micro limited companies. The appeal is obvious: a sort code, a debit card and a working account inside a day, without a relationship manager asking for a business plan.
The friction shows up later, and it usually shows up in one of four places.
The fee hides in the transaction line, not the headline. An account with no monthly charge can still bill you per bank transfer, per cash deposit and per ATM withdrawal. Tide's entry plan, for instance, applies a per-transfer charge and charges for each cash withdrawal, which is fine for a consultant paid by bank transfer and painful for a shop taking notes and coins.
Cash is where the gap widens. Mettle, built by NatWest for the self-employed, does not accept cash deposits at all. Starling takes cash at Post Office counters and charges a percentage of the deposit with a minimum fee. If your week involves a market stall in Birmingham or a farm shop in Devon, that single detail can decide the whole comparison.
Credit is often missing. Most app-first accounts offer no overdraft, no charge card and no CHAPS payments. A short cash-flow gap then falls entirely on your own reserves. High street products still do that job better.
Admin creep is the fourth. Making Tax Digital for Income Tax now applies to self-employed people with qualifying income above £50,000, and the rhythm of quarterly updates changes how you file. Whichever account you pick, it should talk to FreeAgent, Xero or QuickBooks without you retyping numbers.
What each provider actually does well
| Provider | Monthly cost | Stands out for | Watch out for | Best fit |
|---|
| Starling Business | No monthly fee | No UK payment charges, built-in bookkeeping, multi-director access, switching handled in-app | Cash deposits charged at a percentage with a minimum fee; no overdraft on the standard account | Sole traders and small limited companies paid mostly by transfer or card |
| Tide | Entry plan at no monthly fee; paid plans from £12.49 + VAT | Invoicing tools, add-on modules, long list of accounting integrations | Per-transfer charge and cash fees on the entry plan | Firms that want tiered plans and invoice automation |
| Mettle (NatWest) | No monthly fee, no transaction charges | FreeAgent connection at no extra cost, tax pots, in-app invoicing | No cash deposits, no credit, up to two owners, £1m balance cap | Sole traders and micro companies that run card and transfer only |
| Monzo Business | Lite tier at no monthly fee; paid Pro tier | Clear app, pots for tax and expenses, straightforward statements | Leaner feature set for anything complex | Freelancers who value simplicity over extras |
| HSBC Kinetic / NatWest start-up account | Introductory no-fee period, then a monthly charge | Branch access, lending, relationship support | The no-fee window comes with turnover and trading-age conditions | Businesses that expect to borrow or want a physical branch |
International work deserves its own look. Wise Business, Revolut Business and Airwallex handle multiple currencies and mid-market rates well, but check the licence before you commit. Deposits held with a licensed bank are covered by the Financial Services Compensation Scheme. Money sitting with an e-money institution is safeguarded differently, and that distinction matters if you keep a large balance for VAT or payroll.
Notes, coins and the quirks of the four nations
Scottish and Northern Irish banknotes are not legal tender in England and Wales, which surprises visiting customers and occasionally new staff. They are still widely accepted, but a business that banks them regularly is better served by a provider with a clear cash route than by one that refuses deposits outright. Post Office counters remain the practical deposit point for most app-based accounts, and they are the reason cash-heavy firms in rural Scotland and Wales can use digital banking at all.
Switching is less painful than most owners expect. The Current Account Switch Service moves Direct Debits, standing orders and incoming payments, and redirects payments sent to the old account for three years. Starling and the high street banks both run the process in-app or over the phone, and the guarantee covers interest and charges if something goes wrong.
A pattern worth copying
A freelance copywriter in Manchester started on a no-monthly-fee account, put every invoice through it, and set a rule that moved a percentage of each payment into a tax pot. When the first quarterly update arrived, the figures were already categorised and the filing took an afternoon rather than a weekend. The account did not do anything clever. The habit did.
Opening one without wasting a week
Register the business first. A limited company needs its Companies House number; a sole trader needs to be registered for Self Assessment with HMRC. Applications stall at this step more than any other.
Check eligibility before you download anything. Most providers want a UK mobile number and a UK address. Some accept directors living abroad, but ownership usually has to sit with UK tax residents.
Be honest about your payment mix. Count how many transfers, card payments and cash deposits you handled last month, then price each option against those real numbers rather than the marketing page.
Connect your accounting software in the first week. A bank feed that works from day one saves more time than a marginally lower fee ever will.
Switch properly if you are moving. Leave the old account open for a month after the switch date, confirm that Direct Debits have landed, and keep the final statement for your records.
Review once a year. Pull the fee summary, add up what you actually paid, and compare it with the plan above you. Plenty of owners quietly outgrow an entry tier and never notice.
Free guidance is available if the decision feels bigger than a form: Business Wales, Scottish Enterprise, Invest NI and the local growth hubs all run sessions on starting and running a company, and the British Business Bank publishes plain-language material on business finance.
Pick the account that matches the money you actually handle, not the one with the best homepage. Then watch your first three statements closely, because that is where the real price of "no monthly fee" becomes visible.
