Best UK Business Bank Accounts for Sole Traders and Small Companies (2026)

UK founders have an embarrassment of riches that American solo founders would envy: app-first business accounts with no monthly fee, proper banking licences, and — in a couple of cases — full accounting software thrown in free. The catch is only that the options look interchangeable from the outside. They aren't; they split by what you're running (sole trader vs limited company), how you get paid, and how much admin you want the bank to absorb. (US reader? This is our UK guide — the American picks live in the US edition.)

First: do you actually need one?

Limited company: yes, non-negotiable. The company is a separate legal person; its money must live in its own account, and mixing it with yours undermines the separation you incorporated for. Sole trader: not legally required — but most personal accounts' terms prohibit business use, and the practical case is overwhelming anyway: clean records for Self Assessment, professional payment details on invoices, and a tax pot that isn't mentally entangled with the holiday fund. If you've just registered as a sole trader, this is the same-week job.

The quick comparison

The picks, explained

Starling — the default, and deservedly

A real bank (full UK licence, FSCS-protected deposits) with no monthly fee, no payment charges on normal usage, and the category's best app: instant notifications, virtual "Spaces" for tax set-asides, clean accounting integrations. Works for sole traders and limited companies alike. If you don't have a specific reason to choose something else, choose Starling and get on with your week.

Mettle — the free-FreeAgent play

NatWest's app-only business bank is free and competent — but the headline is the bundle: full FreeAgent accounting software included at no cost (normally £150+/year), which for a freelancer heading into Self Assessment is a genuinely large subsidy. If FreeAgent is the software you'd choose anyway (it's our UK pick), Mettle effectively pays you to bank there. Limits: it's for sole traders and small ltds, and it's app-only with modest feature depth beyond the bundle.

Tide — banking plus an admin layer

Tide leans into being a business admin platform: invoicing from the app, expense cards, categorisation, integrations — useful machinery if you'd otherwise buy tools separately. Free tier available, paid tiers as usage grows. One thing to understand rather than fear: parts of Tide's service operate as an e-money/partner-bank arrangement rather than Tide holding its own full banking licence — money is safeguarded or held with licensed partners, but the protection mechanics differ from a straightforward FSCS bank like Starling. Read their current explanation and decide if it matters for your balances.

Monzo Business — for the Monzo faithful

If your personal banking lives in Monzo, the business account (free Lite tier, Pro at ~£5/month with tax pots and invoicing) will feel like home, and it's a proper FSCS-protected bank. Chosen mostly for interface loyalty rather than any single killer feature — which is a perfectly good reason.

Revolut Business — the international specialist

Multi-currency accounts and cheap FX make Revolut the pick when clients pay you in dollars and euros — the fees saved on conversion can dwarf any monthly charge. Its UK banking arrangements have matured in recent years, but as with Tide, check the current protection position for the entity actually holding your money. For purely domestic UK work, simpler options serve better.

The high street — the deliberate choice

Barclays, HSBC, NatWest, Lloyds and friends still make sense in three cases: you handle real cash (paying-in at branches), you want an established lender relationship for future borrowing, or a landlord/franchise insists. Expect a monthly fee (~£8–12) after the customary free introductory year, and an app experience a generation behind the fintechs. Nothing wrong here — just choose it for one of those reasons, not by default.

Opening one: what you'll need

App-first providers typically approve in a day or two: photo ID, proof of address, your business details — plus your company number and directors' details for a limited company (have your Companies House incorporation done first). Then the same-week setup that makes any account earn its keep: connect your accounting software, create a tax pot with an automatic percentage rule (25–30% of profit — the set-aside habit), and move every business payment across cleanly.

Free, FSCS-protected and app-first is the UK's default answer. The only real question is whether a bundle – FreeAgent, admin tools, cheap FX – tips you elsewhere.

Frequently asked questions

Do I need a business bank account as a sole trader in the UK?

Not legally — sole traders can bank in a personal account. Practically, yes: most personal accounts' terms prohibit business use, and separate banking makes Self Assessment records, invoicing and tax set-asides dramatically easier. Limited companies have no choice: the company's money must sit in the company's own account.

Which UK business bank accounts are actually free?

Starling and Mettle are genuinely free with no monthly fee; Monzo Business Lite and Tide's entry tier are free with paid upgrades above. High-street banks typically offer a free introductory period (often 12 months) before ~£8–12 monthly fees begin — worth knowing before the anniversary quietly arrives.

Is Starling or Tide better for a small business?

Starling for straightforward banking done excellently — full FSCS-protected bank, free, best-in-class app. Tide when you'll actually use its built-in admin layer (invoicing, expense tools) and are comfortable with its partner-bank/e-money protection structure. For most sole traders and small ltds, Starling is the safer default.

Are app-only business banks FSCS protected?

The ones with full UK banking licences are — Starling, Monzo and Mettle (part of NatWest) protect eligible deposits up to the standard FSCS limit. E-money and partner-bank arrangements (parts of Tide's and some Revolut services) safeguard funds differently rather than via direct FSCS cover — check the current terms of whichever entity holds your money.
