How to open a business bank account (step-by-step) in 2026

Key takeaways:

• Opening a business bank account usually involves choosing a provider, sharing information about the business and its owners, completing KYC and identity checks, setting account permissions, and then activating and funding the account.
•  
• A dedicated business bank account helps keep business and personal finances separate, while also giving access to features such as bulk payments, accounting software integrations, debit cards and overdraft facilities.
•  
• The right business account should be chosen on more than price alone. Banking fees, payment capabilities, savings options, accounting integrations and access to a relationship manager can all affect how useful the account is as the business grows.

Sorting your business banking is one of the key pieces of admin to complete before you really get your business up and running.

You might not have done it before or it might have been a long time since you last set up a business bank account. Either way, it’s a process that nobody really teaches you.

That’s why so many people end up using their personal bank for their business banking – even if there are better options out there. And there almost certainly are better options. In an increasingly competitive market, business banking can add a lot of value to new and established businesses alike.

Don’t let uncertainty around the process put you off choosing the most valuable bank for your situation. We’ve explained all the details below; here's how to open a bank account for business.

What is a business bank account and why do you need one?

Out of everything that goes into running a business, having a dedicated bank account is one of the essentials.

The reason a limited company will need a business bank account is fairly straightforward: it’s a legal requirement for them to do so.

Sole traders don’t have the same legal obligation, but it’s considered best practice for the sake of financial management.

What a business bank account does

A business bank account is exclusively for your business.

They work in mostly the same ways, with a few specific features designed to make your business finances easier to manage.

Key features to look for in a business bank account

Business current accounts operate in largely the same way as retail current accounts.

Money can be transferred in and out of it – for example, a payment from a customer, or to pay staff. You can set up direct debits, order and use debit cards, and apply for overdraft facilities.

Depending on which provider you go for, business accounts differ from personal current accounts in a few ways:

• You can have multiple (2+) signatories

• You can make bulk payments (e.g. payroll or other payment runs)

• Many integrate with accounting software, like Xero or Sage, for easier bookkeeping

• They have different costs (usually outlined in a document called ‘fee tariffs’ or ‘rates and charges’)

• They can come with a dedicated relationship manager or other business-specific perks

And for more established businesses, you may want an account that helps with payroll runs, multiple cardholders and integrates your accounting software (like Xero or Sage).

What you need to open a business bank account

• Business details
• Director and shareholder information
• Proof of identity
• Proof of UK address

Note that businesses with more complex ownership structures or multiple directors may be asked for additional documentation. For more, see our blog about the documents needed for a business bank account.

How to open a business bank account step-by-step

There isn’t a universal process for opening business bank accounts, so you might find your experience differs slightly from the steps we’ve listed below. Equally, there isn’t huge room for difference. Most banks will have fairly similar processes.

To give you as much insight as possible, we’ll lay out an end-to-end overview of the application process and how to set up a business bank account. After that, we’ll share the specifics of our process at Allica Bank for the clearest possible example.

1) Choose the right business bank for your business

Probably the most important step in the process – actually deciding which account to open!

This is your choice; every bank offers something different. You might want low-cost international transfers or a high interest rate savings account. There’s a good amount of choice in the market at the moment, so it pays to do your research.

Maybe you're looking for one with a relationship manager, payment allowances, accounting software integration and cashback that could offset monthly costs.

2) Start your application, share key information

Once you’ve found your bank, you’ll start their application process. This might be an online form, over the phone or in-person.

Different banks want different information, but all of them will require at an absolute minimum:

• Your business name

• The type of entity your business is

• Your business’ directors, shareholders and ultimate beneficial owners

3) Identity verification and KYC checks

It’s then over to the bank to identify and verify your business.

They’ll do this by carrying out searches with Companies House, as well as requesting proof of identity and proof of UK address for the directors and controlling shareholders. 

Commonly-accepted ID documents include:

• Copy of a passport

• Copy of a driving licence

And for proof of address:

• Council tax bill

• Utility bill

• Mortgage statement

Know Your Customer (KYC) checks are a regulatory requirement for banks and other financial institutions. This is an anti-money laundering measure that confirms that you are who you say you are, that you’re eligible to open the account and whether you’re considered a risk.

The ID checks in step three will have confirmed you’re a real person. However, many banks will want to confirm that you are the same person as the ID documents show. This is often done using biometric technology. You might be asked to take a photo of yourself to compare against your ID, for example.

If any of the persons with significant control in your business have records of financial crime, come from sanctioned areas or other adjudged high-risk locations, you’ll be asked to share more information with the bank.

4) How banks assess your business before opening an account

Once you’ve cleared the KYC checks, which should be a formality for any legitimate UK business, the bank will move on to understanding your specific situation.

They’ll want to understand:

• The nature of your business

• How you intend to use the account

• How you’ll continue to fund the account

• Where the initial deposit in the account will originate from

These questions are to help the bank tailor the product to you, as well as completing some final anti-money laundering checks.

6) Setting permissions on your business bank account

Finally, the bank will need to know who in your business needs access to the bank account and what types of rights they will need.

For example, you might want two-person payment authorisation or to restrict some users to read-only access. In large businesses, there could be a dozen staff with legitimate cause to access the account. Setting their permissions correctly is an important step for compliance and security.

7) Issuance of credentials

After all of those checks and steps in the due diligence process, your new bank will then issue you with your online banking login credentials.

From here, you’ll be able to activate, set up, fund, and start operating the account.

According to Gareth Anderson, Allica Bank’s Head of Business Management: “whilst it depends on the complexity of the business and its ownership structure, typically – from start to finish – a bank will look to have the account opened within a few days.”
