The best free business bank accounts UK has right now aren’t hard to find — but they’re easy to confuse with ones that are only free for six months, or free only if you don’t do much banking. This guide cuts through that. Every account here is genuinely free on its core tier, FCA-regulated or properly safeguarded, and worth considering in 2026 — for sole traders, limited companies, and freelancers alike.

How We Selected These Accounts

Every account in this guide to free business bank accounts UK had to clear three tests: no monthly fee on the core account — permanently, not as an introductory offer — a live and accessible application process right now, and either full FCA banking authorisation or FCA e-money regulation with properly safeguarded client funds.

Accounts that hide useful features — accounting integrations, UK transfers, invoicing — behind a mandatory paid upgrade weren’t ranked as free options. They were noted where relevant, but they’re not free accounts. That distinction matters.

The Best Free Business Bank Accounts UK 2026 — At a Glance

Starling Bank — Best Free Business Bank Account Overall

Starling is the benchmark. Every other free account gets measured against it, and most fall short somewhere. There’s no monthly fee, no charge on UK transfers, and no features gated behind a paid plan that you’d actually want on a free account. It’s a fully licensed UK bank — regulated by both the FCA and PRA — so eligible deposits are FSCS protected up to £85,000. You can verify Starling’s regulated status on the FCA register.

Pricing

£0/month. Free UK payments and transfers. International transfers available at a flat fee plus 0.4% FX charge. Cash deposits at Post Office branches cost 0.3% of the amount, minimum £3. No minimum balance.

Key Features

Free accounting integrations with Xero, QuickBooks, and FreeAgent — no upgrade required. Cheque deposits via the Starling app. Overdraft facility available for eligible businesses. EUR and USD currency accounts available as paid add-ons. Sole traders and limited companies both eligible. Access limited to company directors — no team expense cards on the free tier.

Best For

Sole traders and limited companies that want the most complete free account on the market. If you’re already using Xero or QuickBooks, the bank feed connects directly at no extra cost. That alone makes this the default recommendation for most UK businesses. For a direct comparison with Tide, see our Starling vs Tide business account comparison.

Tide — Best Free Account with Built-In Invoicing

Tide is different from Starling in one important way: it’s not a bank. It’s an FCA-authorised e-money institution, with business accounts held by ClearBank — a licensed UK bank — which is how deposits get FSCS protection. In day-to-day terms that distinction rarely matters. What does matter is that the core account is free, UK transfers cost 20p each after five free per month, and the invoicing tool is built in from day one.

20p per transfer sounds trivial — and for most businesses, it is. If you’re making 30 transfers a month, that’s £5. Factor in the cashback offers Tide regularly runs, and the core account is effectively free for any reasonable transaction volume.

Pricing

£0/month on the core account. UK transfers: 20p each, five free per month. Tide is currently offering £100 cashback for new customers signing up by 30 June 2026 (T&Cs apply; new customers only). Paid plans from £9.99/month add team accounts, expense cards, and priority support.

Key Features

Built-in invoicing and receipt capture. Accounting integrations with Xero, QuickBooks, and FreeAgent. Instant savings account available alongside the current account (up to 4% AER variable, tiered, terms apply). Company registration via Companies House available directly through the app (£24.99). Fully digital — no branches.

Best For

Sole traders and small limited companies that want invoicing built into their banking. Also strong for new businesses that want to register and bank in one workflow without juggling multiple tools.

Monzo Business Lite — Best for Existing Monzo Personal Customers

Here’s the honest assessment of Monzo Business Lite: it’s fine if you’re already a Monzo personal customer and want a clean separation of business and personal finances within one app. For everyone else, it’s a weaker choice than Starling or Mettle at zero cost.

The free Lite tier covers UK transfers and basic categorisation. That’s it. Accounting software integrations — gone. Invoicing tools — gone. Multi-user access — gone. You’ll need Business Pro for all of those, which now costs £9/month (up from £5/month). Frankly, Starling offers more for free, with fewer caveats.

Pricing

£0/month on Business Lite. Business Pro: £9/month. Free UK bank transfers. Cash deposits at PayPoint: £1 per deposit, capped at £300 per transaction and £1,000 per rolling six months. No IBAN — so no international transfers, on any tier.

Key Features

Free UK transfers and direct debits. Spending categorisation via Pots. No accounting integrations on the free tier. No invoicing without upgrading. No international payment capability. FSCS protected as a fully licensed UK bank. Personal and business accounts visible within the same app.

Best For

Business owners already embedded in the Monzo ecosystem who want their business account alongside their personal one. Not the right call if you’re starting fresh and need accounting integrations or invoicing without a monthly cost.

Mettle by NatWest — Best Completely Free Account Including FreeAgent

Mettle doesn’t get mentioned as often as Starling or Monzo. It should. The account is permanently free — not for 12 months, not with conditions — and it includes FreeAgent accounting software at no cost. FreeAgent typically costs around £19/month when purchased separately. If you need it, Mettle just made that cost disappear.

Eligibility is tighter than the challenger banks: sole traders and limited companies with up to two owners only, and no cash deposits. If those constraints don’t apply to your business, this is one of the most cost-effective accounts available.

Pricing

£0/month. Free domestic UK transfers. FreeAgent included at no additional cost. No cash deposits — digital transactions only.

Key Features

FreeAgent accounting software included — covering invoicing, expense tracking, VAT returns, and Self Assessment preparation. Sync options for Xero and QuickBooks. Transaction categorisation. Instant payment notifications. FSCS protected as part of NatWest Group. Available to sole traders and limited companies with up to two directors.

Best For

Small limited companies and sole traders who need FreeAgent. The bundled software makes Mettle genuinely cheaper to run than most alternatives once accounting costs are included in the calculation.

Best Free Business Bank Accounts for Sole Traders in the UK

Sole traders aren’t legally required to hold a separate business account — unlike limited companies, where it’s a legal obligation under Companies House registration rules. That said, mixing business and personal finances creates real problems at Self Assessment time, and most accountants will tell you to separate them from day one.

Among the free business bank accounts UK currently offers for sole traders, Starling is the strongest overall: permanently free, accounting-integrated, no transaction volume constraints. Mettle is the better choice if you want FreeAgent included. If you’re approaching the Making Tax Digital threshold for Income Tax — which applies from April 2026 for qualifying sole traders — your banking and accounting software choices are increasingly connected. Read our guide to Making Tax Digital requirements for sole traders for the full picture.

Accounting Software Integration — Does Your Free Account Connect?

The banking question and the accounting question are the same question, really. An account without a direct integration forces you into manual CSV exports or re-entry — which is time you don’t get back, every month.

Starling, Tide, and Mettle all include accounting integrations on their free tiers. Monzo Business Lite doesn’t. If you haven’t decided between Xero and QuickBooks yet, both connect to Starling and Tide via direct bank feed — meaning transactions sync automatically without any manual work on your end. Our Xero vs QuickBooks UK — which works best with your bank comparison covers the full picture.

When a Free Account Is Not Enough — Paid Options Worth Considering

Most sole traders, freelancers, and early-stage companies won’t hit the limits of a free account for the first couple of years. When you do — team members needing expense cards, higher transaction volumes, overdraft requirements, multi-currency accounts — the friction becomes real.

If you’re past that point, or you want to compare the full market including HSBC Kinetic, Lloyds, Barclays, and the paid tiers of Starling and Tide, our full UK business banking comparison covers paid accounts, introductory free periods, overdraft facilities, and business lending products in full.

FAQ

Which free business bank account is best for a UK limited company?

Starling and Mettle. Starling is permanently free, fully FSCS protected, and includes accounting integrations from day one. Mettle bundles FreeAgent — which is the stronger pick if accounting software is already a line item in your budget.

Is Tide a real bank account?

Tide is FCA-authorised but not a licensed bank. Business accounts sit with ClearBank — a licensed UK bank — which means eligible deposits carry FSCS protection. For everyday business banking, the distinction rarely matters in practice.

Do free business bank accounts affect business loan eligibility?

Not directly. Your account type doesn’t determine loan eligibility on its own. That said, high street banks like Lloyds and NatWest often look more favourably on existing customers when assessing business lending. If you’re likely to need business finance within the next 12–24 months, that relationship is worth establishing early.

Can a sole trader use a personal account for business?

Legally, yes. There’s no statutory requirement for sole traders to hold a separate business account. In practice, it’s a bad idea — mixing finances makes Self Assessment harder, creates problems if HMRC requests records, and looks unprofessional to clients and suppliers. Every account on this list is free to open. There’s no good reason not to separate from day one.
