Haven't incorporated your company yet?
How to set up your first business bank account after incorporating your UK limited company is one of the first practical steps once you’ve gone through incorporation.
A dedicated business current account keeps your personal and company finances separate, simplifies tax compliance, and shows suppliers and investors you mean business.
If you haven’t yet taken the first step, you can register your company quickly and easily online.
In this guide, we’ll:
- Explain why a business bank account matters for a new company
- Show you what documents you’ll need to apply
- Compare the best business banking accounts for startups

- Cover special cases, like dormant companies or changing directors
Why you need a business bank account for your limited company
Once your company is incorporated, setting up a business bank account should be one of the first things on your list. It’s not just a formality; it separates your company’s finances from your own. That separation is crucial for compliance, professionalism, and growth.
Keep your taxes simple
Using a business current account means every transaction linked to your company is in one place. This makes bookkeeping straightforward and avoids confusion when it’s time to prepare annual accounts or a Corporation Tax return. HMRC expects accuracy, and a clear record of business-only transactions makes life far easier.
Protect yourself legally
As a director, you have a legal responsibility to keep the company’s money separate from your personal funds. Blurring the line by using your personal account risks creating compliance issues. In the worst case, it could even weaken the “limited liability” protection of your company if you were ever challenged—one of many benefits of a Limited Company.
Look professional to customers and suppliers
Paying from a dedicated business account adds credibility. Clients are reassured when invoices come from a company account, not a personal one. Likewise, suppliers and partners are more comfortable dealing with a business that clearly operates in its own name. It signals stability and legitimacy.
Lay the groundwork for finance
If you ever want a business loan, credit card, or even an overdraft facility, a business bank account is a must. Lenders expect to see company accounts, not personal ones. Opening one early builds a financial history in your company’s name, which can support applications later.
Stay investor-ready
If you plan to bring in outside investment, investors will expect clean, separate financial records. Having a business current account from day one shows you’re organised and gives them confidence that their money will be handled properly.
In short, while it’s possible to limp along using your personal account, it puts you at a disadvantage. The end goal is to build a company that’s credible, compliant, and set up for growth.

What you need to set up your first business bank account
Banks will want to verify both your company and the people running it before opening a business account. Having the right documents ready will save time and avoid delays. While requirements vary slightly between providers, most ask for the following:
Company registration details
You’ll need your Companies House registration number and incorporation documents (the certificate of incorporation and Memorandum and Articles of Association). These confirm your company is officially registered and outline its structure.
Proof of identity
Each director and any shareholder with significant control must provide ID, usually a passport or UK driving licence. Digital banks may let you upload a photo or video, while traditional banks often require an in-branch check.
Proof of address
Directors and shareholders usually need to show a recent utility bill, bank statement, or council tax bill—generally dated within the last three months. This confirms residency and helps the bank meet anti-money-laundering rules.
Business information
Expect to be asked about your company’s nature, industry sector, expected turnover, and typical transaction volumes. Banks use this to assess risk and to tailor services. For more information, read HMRC’s official guidance on business bank accounts.
Other possible requirements
- A business plan, if you’re applying for credit at the same time.
- Details of all people who will be authorised signatories on the account.
- For non-UK residents, additional documents or checks may be required, depending on the bank.
If you're applying for your first business current account as a startup, keep your answers simple and realistic. Banks aren't expecting detailed trading history, just a clear picture of your plans.
Choosing the best business banking accounts for startups
When you set up your first business bank account, you’ll see two main options: traditional high-street banks or modern digital providers. Both can work, but for most new companies, the speed, simplicity, and cost-effectiveness of digital banking is hard to beat.
Why digital business accounts are popular with startups
Digital banks often have:
- Faster applications, with approvals sometimes within hours.
- Lower fees, especially in the early stages.
- Easy integration with accounting software.
- User-friendly apps for managing money on the go.
A clean record from day one also helps your company credit score.
Why we recommend Countingup for your first business current account
Countingup is designed specifically for startups and small companies. It combines a business current account with built-in bookkeeping tools, which means you can manage both banking and accounting in one app. For a newly incorporated business, this cuts down admin and helps you stay compliant from day one.
Key benefits of Countingup include:
- Quick online setup, with no need to visit a branch.
- Real-time categorisation of transactions to simplify tax returns and self assessment expenses.
- Invoicing tools built into the app.
- Clear pricing, with free and low-cost plans that scale as your company grows.
This makes Countingup one of the best business banking accounts for startups that want to keep things lean and efficient without compromising on compliance.
Other options to consider
If your business handles a lot of cash or you need in-person branch services, a high-street bank like Barclays or Lloyds may be a better fit.
Challenger banks such as Starling also offer strong app-based accounts. But for most limited companies just starting out, a dedicated digital business account like Countingup is often the simplest and most effective option.
Step-by-step: how to set up your first business bank account
Step 1: Compare providers
Decide what you need from a business current account. Speed of setup, fees, cash handling, and integrations all matter. Digital providers suit most startups that want quick approval and low admin. High street banks suit cash-heavy or branch-reliant businesses.
Step 2: Gather your documents
Have everything ready to avoid back-and-forth:
- Companies House number and incorporation documents
- Photo ID for all directors and any PSCs
- Recent proof of address for those individuals
- Basic business details, expected turnover, and who will be authorised on the account
Step 3: Apply online or in branch
Most digital banks let you apply in-app and upload documents. Traditional banks may ask for an appointment. Keep your descriptions simple and consistent with your incorporation details.
Step 4: Complete checks and approval
The bank will run identity, address, and company checks. They may request extra information about your activity or source of funds. Respond quickly to keep the process moving.
Step 5: Start using your account
Once approved, you’ll receive your sort code and account number. Then:
- Set up online banking and user permissions
- Connect your business account to your accounting software
- Create invoice templates and payment references
- Move recurring costs to the new account and cancel any personal-account direct debits used for the business.
Keep all company records on the business account from day one. It keeps records clean and makes tax time easier.
Special cases when setting up your first business bank account
Not every company follows the same path after incorporation. Here are a few situations to keep in mind:
- Dormant companies – No need to open a business current account until you start trading. Using one could accidentally trigger trading status; file dormant accounts until you go live.
- Adding or removing directors – Banks will need updated signatory details. New directors must provide ID, proof of address, and may face a credit check.
- Changing your company name – You’ll need to update your bank with the official Companies House change of name certificate.
- Audits – While most small companies don’t need one, if an audit is carried out, a clear business account record makes the process much easier.

FAQs on setting up your first business bank account
Do I legally need a business bank account for my limited company?
Yes. A limited company is a separate legal entity, so it must have its own business current account for trading. Sole traders can use personal accounts, but limited companies cannot.
Can I use my personal account instead?
Strongly discouraged. Using a personal account blurs the line between company and personal funds. It risks compliance issues and weakens your limited liability protection.
What documents are required to set up my first business bank account?
Typically you’ll need your Companies House incorporation documents, ID and proof of address for directors, and basic business details like your industry and expected turnover.
How long does it take to open a business account?
Digital banks can approve applications in a day or two, while traditional banks may take several weeks, depending on checks and appointments.
Do I need a business account if my company is dormant?
No. Dormant companies should avoid opening an account until they start trading; otherwise HMRC may treat them as active.
Can non-UK residents open a UK business bank account?
Yes, but requirements vary. Some digital providers accept non-UK directors, while high street banks often ask for additional documents or may decline entirely.
What happens if I change my company name?
You must update your business account once Companies House has approved the name change and issued a certificate. Banks require this certificate to amend account details.
