How to Open a Business Bank Account in the UK

Do you actually need one?

Limited companies effectively must have a separate account because the company is a different legal person from you. Sole traders are not legally required to, but most personal account terms prohibit business use, and mixing money makes Self Assessment painful. Open one regardless of structure — it's free with most providers and saves hours of bookkeeping a year.

How to compare providers without overthinking it

For a typical small business, the comparison comes down to a handful of factors:

• Monthly fee and how long any introductory free period lasts.
• Transaction allowance on bank transfers, with the per-transaction fee after that.
• Cash deposit cost and limits — much higher relevance for trades and retail than for a typical freelancer.
• FX rates and fees if you bill or pay internationally.
• Integrations with your accounting software (Xero, FreeAgent, QuickBooks).
• Features bundled in — invoicing, payment links, expense cards, accounting links.
• Deposit protection: fully-licensed UK banks are FSCS-covered up to £85,000; e-money providers safeguard funds under different rules.

Documents you'll need

The application, step by step

1. Shortlist 2–3 providers. Use the comparison criteria above. Don't waste time on full applications until you've shortlisted.
2. Open the app-based application first. Most can be completed in under an hour. Photograph your ID, fill in business details, complete the identity verification selfie.
3. Wait for KYC checks. Decisions vary from minutes to several working days, longer for complex structures.
4. Activate the account. Cards arrive in 3–5 working days. Set up online banking and your security details.
5. Connect to your accounting software via Open Banking — this is the single biggest time saver and is free with all major providers.

If your application is rejected

Rejections happen and aren't necessarily about you. Common reasons:

• Identity verification failures — usually because of a poor photo of ID or a mismatch between addresses on different documents.
• Industry restrictions — some providers don't accept certain industries (gambling, crypto, adult, cannabis, some money services). Their terms list excluded sectors.
• Adverse credit on a director — for limited companies, directors' personal credit is checked at most providers.
• Incomplete business description — "consulting" is too vague; "B2B software consulting for UK SMEs" is better.

If rejected, you can usually apply with another provider straight away. Many founders open with one provider, then add a second once they have a few months of trading history.

After opening — set it up properly

1. Connect the account to your accounting software via Open Banking.
2. Update your invoice template with the new bank details.
3. Set up Direct Debits for HMRC, software subscriptions and recurring suppliers.
4. Configure transfer limits and approvals if you have co-directors or staff.
5. Order any additional cards you'll need.
6. Set a calendar reminder at 90 days to review whether the account is still the right fit.
