Best Business Bank Accounts for UK Sole Traders (2026)

UK sole traders are not legally required to have a separate business bank account — unlike limited companies, you and your business are the same legal entity under UK law. But keeping your business finances separate from your personal spending is one of the most practical decisions you can make. It makes your bookkeeping cleaner, your accounting software bank feeds more accurate, and your annual tax return significantly less painful.

This guide covers the best business bank accounts for UK sole traders in 2026, focusing on accounts designed for one-person businesses rather than large corporates. We cover pricing, key features, and how each account integrates with accounting software for MTD compliance.

Why a separate business bank account matters

A dedicated account is useful for straightforward practical reasons — but it matters more than ever now that Making Tax Digital for Income Tax is under way. MTD requires digital record keeping, and accounting software works far better when it connects to a business account containing only business transactions. Mixed personal and business transactions create noise in your bank feed, forcing you to manually review and exclude personal spending every time you reconcile.

Beyond the administrative benefits:

• Bookkeeping is faster — every transaction in the account is business-related by definition
• Cash flow is clearer — you can see your business position without filtering out personal spending
• Invoicing looks more professional — clients pay into a dedicated business account, not a personal current account
• Tax preparation is simpler — your year-end totals are already separated

Most digital business accounts can be opened in 10 minutes from your phone. There is very little reason to delay.

Starling Bank Business — best all-round free business bank account for sole traders

Monthly fee: Free (Business Pro available at £7/month for additional features)

Starling's business account is consistently rated one of the best in the UK for sole traders and small businesses. It connects directly to FreeAgent, Xero, and QuickBooks via automatic bank feeds — which means your transactions flow into your accounting software without manual imports.

Key features on the free account:

• No monthly fee and no charge for standard UK bank transfers
• Real-time spending notifications and categorisation
• Spaces (sub-accounts) for setting aside money — useful for tax saving
• Full integration with leading accounting software
• 24/7 in-app customer support rated well by users

The main limitation is that Starling is digital-only — there is no branch network and no facility to deposit cash or cheques. For most sole traders (particularly service businesses, freelancers, and consultants) this is rarely an issue. If you regularly receive cash payments or cheques, you will need a workaround such as depositing via Post Office (available on some accounts).

Best for: Most sole traders wanting a free, well-integrated account with no hidden fees.

Tide — best business bank account for invoicing-heavy sole traders

Monthly fee: Free tier available; paid plans from £9.99/month

Tide was built specifically for small businesses and sole traders, and it shows in the invoicing tools. You can create, send, and chase invoices directly from the app — without needing separate invoicing software. The free account covers this alongside standard banking.

Tide integrates with Xero, QuickBooks, Sage, and FreeAgent, and supports automatic expense categorisation.

The trade-offs worth knowing about: customer support on the free plan can be slower to respond than Starling, and some users have reported occasional account reviews causing temporary access delays. Tide is regulated as an e-money institution rather than a full bank, which means deposits are not covered by the Financial Services Compensation Scheme (FSCS) in the same way as bank accounts — worth understanding before depositing large sums.

Best for: Sole traders who invoice frequently and want invoicing and banking in one place.

Mettle by NatWest — best business bank account for FreeAgent users

Monthly fee: Free

Mettle is NatWest's digital business account aimed squarely at sole traders and small businesses. On its own, it is a solid free account with the backing of NatWest Group. But the headline feature is the FreeAgent integration — Mettle customers get a free FreeAgent subscription, which is otherwise from £19/month for a sole trader on a direct plan.

For anyone who has assessed their options and decided FreeAgent is the right accounting software — and it is the strongest choice for many UK freelancers — Mettle turns what would be a monthly cost into a free bundle. Bank account plus MTD-ready accounting software, both for nothing.

Mettle's account features are somewhat more limited than Starling's — fewer integrations, no Spaces equivalent, and a less mature product overall. But for a straightforward sole trader prioritising cost, the Mettle + FreeAgent combination is hard to beat.

Best for: Sole traders who plan to use FreeAgent for accounting and MTD compliance.

Monzo Business — best for automatic tax pot automation

Monthly fee: Free (Lite); £9/month (Pro)

Monzo Business brings the familiar Monzo consumer app experience to business banking. The free Lite account covers the basics: card payments, bank transfers, and transaction history. The Pro account (£9/month) adds the features that make Monzo genuinely useful for a sole trader: tax pots, accounting integrations, and expense cards for subcontractors.

The tax pot feature is particularly useful if you struggle to set aside money for your Self Assessment bill. You can configure a rule to automatically move a percentage of each incoming payment into a ring-fenced pot — so you are never caught short when January comes around. See our guide to choosing the right accounting software for how Monzo Pro pairs with MTD-compatible tools.

The downside: unlike Starling's free account, the accounting integrations (Xero, FreeAgent) are only available on the paid Pro plan. If software integration matters to you and you do not want to pay for Pro, Starling or Mettle are better choices.

Best for: Existing Monzo personal account users, or those who want automatic tax saving built into their banking.

Traditional high street banks

Barclays, HSBC, Lloyds, and NatWest all offer business current accounts for sole traders. They tend to come with monthly fees (typically £5–£12/month), branch access, and facilities for cash and cheque deposits.

For sole traders who rarely handle cash, operate entirely digitally, and do not need in-branch support, the digital-first options above are usually better value. The main reason to choose a traditional bank is if you regularly deposit cash or need the reassurance of a branch network. Traditional banks also tend to have more established lending relationships, which may matter if you need a business overdraft or loan later.

How to choose the right business bank account as a sole trader

If you want a free account with no conditions: Starling Business is the default recommendation — the feature set is strong, integrations are excellent, and there are no hidden fees or qualifying requirements.

If you plan to use FreeAgent: Open a Mettle account. You get both banking and HMRC-recognised MTD accounting software for free.

If you invoice heavily and want invoicing built into banking: Tide handles this better than the others, though be aware of the FSCS protection difference.

If you want automatic tax saving: Monzo Business Pro (£9/month) has the best implementation of this. If you consistently struggle to set aside enough for your tax bill, this feature alone may justify the cost.

If you need cash handling or a branch: A traditional bank such as Barclays or Lloyds is the more practical choice, accepting the monthly fee in return.

For most sole traders — particularly service businesses, freelancers, and consultants who operate digitally — Starling or Mettle will cover everything they need, at no cost. Both can be opened in under 10 minutes from your phone.

Once your banking is in order, make sure your MTD accounting software is set up and connected via bank feed before your MTD obligations begin. If you are unsure which software is right for you, our MTD software chooser asks a few short questions and gives a personalised recommendation.
