How do I set up a business bank account?

At Towerstone Accountants we provide specialist small business accountancy services for owners, directors, and growing businesses across the UK. We created this webpage for small business owners who want clear guidance on managing finances, meeting tax obligations, and making informed decisions without jargon. Our aim is to help you stay compliant, improve cash flow, and build a more resilient business.

Setting up a business bank account is one of the first practical steps you will take when starting a business and yet it is also one of the areas where I see the most uncertainty. In my experience working with sole traders freelancers contractors and limited company directors across the UK many people either delay opening an account or open the wrong type without fully understanding the implications.

A business bank account is not just an administrative task to tick off a list. It plays a central role in how you manage cash flow track profitability meet your tax obligations and present your business professionally. Getting it right early makes everything else easier from bookkeeping to dealing with HMRC to applying for finance in the future.

In this guide I will explain how to set up a business bank account step by step using correct UK practice. I will cover who needs one what documents you will need how to choose the right provider and how to use the account properly once it is open. This is written from real world experience rather than theory and is designed to give you clarity and confidence rather than overwhelm.

What a business bank account actually is

A business bank account is an account used exclusively for business income and business expenses. It is separate from your personal account and is designed to support trading activity rather than day to day personal spending.

The purpose is simple. It keeps business finances clear organised and defensible. When income and expenses flow through a dedicated account it becomes far easier to understand how your business is performing and far easier to prove figures if HMRC ever ask questions.

A proper business account allows you to:

• Receive payments from customers and clients
• Pay suppliers staff and HMRC
• Track income and expenses accurately
• Link directly with accounting software
• Build a clear financial record for lending or investment

While this sounds straightforward the importance of separation cannot be overstated. Mixing personal and business money is one of the most common causes of accounting errors I see.

Do I legally need a business bank account

Whether you legally need a business bank account depends on your business structure.

If you run a limited company then a business bank account is mandatory. A limited company is a separate legal entity and its money must be kept separate from your personal finances. Using a personal account for company money can cause serious issues including breaches of director duties and difficulties proving what belongs to the company.

If you are a sole trader or in a partnership the law does not strictly require a separate account. However most personal bank account terms prohibit business use. Even where permitted I strongly recommend opening a separate account.

From a practical point of view having a business account as a sole trader:

• Makes bookkeeping faster and cheaper
• Reduces the risk of missing allowable expenses
• Makes tax returns more accurate
• Helps you understand real profit
• Protects you during HMRC checks

In practice nearly every sole trader I work with ends up opening one eventually. Doing it early saves time and stress later.

When should I open a business bank account

Timing matters and this depends on how your business is set up.

If you are forming a limited company you should open the business bank account as soon as the company is incorporated. You will need it to pay in share capital receive income and pay expenses. You should not trade through your personal account once the company exists.

If you are a sole trader the best time to open a business account is before you start trading or as soon as you begin taking payments. Even if income is irregular or small at first separation from day one avoids messy clean up work later.

If you are switching from personal to business later you can still do it but you may need to carefully identify which transactions relate to the business when preparing your accounts.

What documents you will need to open a business bank account

Banks are required to carry out identity and anti money laundering checks. The exact documents vary by provider but the following are commonly required.

For sole traders:

• Photo ID such as a passport or driving licence
• Proof of address such as a utility bill or council tax statement
• Your trading name if different from your own name
• Nature of your business and expected activity

For limited companies:

• Certificate of incorporation
• Company number and registered address
• Details of directors and shareholders
• Photo ID and proof of address for directors
• Information about business activity

Some banks will also ask about expected turnover source of funds and whether you trade internationally. This is normal and part of regulatory checks rather than suspicion.

Digital banks often complete this process faster but may still ask for follow up information.

Choosing the right business bank account

There is no single best business bank account. The right choice depends on how you trade how often you transact and what features you actually need.

Traditional high street banks offer stability branch access and familiarity. Fintech banks offer speed lower fees and better integration with software.

When advising clients I encourage them to think about function rather than brand.

Key factors to consider include:

• Monthly fees and transaction charges
• Ease of online and mobile banking
• Integration with accounting software
• Customer support availability
• Cash and cheque handling if needed

If you deal mostly online receive payments by transfer and use accounting software then a digital provider may be ideal. If you handle cash or value branch access a high street bank may suit you better.

High street banks versus digital banks

High street banks such as Barclays Lloyds HSBC and NatWest are well established and often trusted. They offer business managers physical branches and access to lending products.

Digital banks such as Starling Tide Monzo Business and Revolut are app based and focus on simplicity and automation.

From my experience the differences often look like this.

High street banks:

• Physical branches
• More traditional lending options
• Slower onboarding
• Higher fees in some cases

Digital banks:

• Fast account opening
• Strong app based tools
• Easy expense tracking
• Limited cash handling

Neither option is inherently better. The key is alignment with how you actually operate.

Opening the account step by step

While each provider differs slightly the general process is consistent.

First you choose your provider and account type. Make sure it matches your business structure.

Next you complete the application either online or in branch. This includes providing business details and personal identification.

The bank will then complete verification checks. This can take anywhere from minutes to several days depending on complexity.

Once approved you will receive account details cards and online access. At this point you should begin using the account exclusively for business activity.

Setting up the account properly from day one

Opening the account is only the first step. How you use it matters just as much.

I always recommend setting clear boundaries immediately.

You should:

• Pay all business income into the business account
• Pay business expenses only from that account
• Avoid personal spending from the account
• Transfer drawings or salary separately

For limited companies you should pay yourself via payroll or dividends where appropriate rather than dipping into the account.

For sole traders you can transfer money out as drawings but it should be clearly identifiable.

Linking your business bank account to accounting software

One of the biggest advantages of a business bank account is the ability to link it to accounting software such as Xero QuickBooks or FreeAgent.

This allows transactions to feed in automatically saving time and reducing errors.

From a practical point of view this:

• Reduces bookkeeping costs
• Improves accuracy
• Makes VAT returns easier
• Provides real time financial insight

When accounts are linked properly it becomes much easier to understand how your business is performing month by month rather than waiting until year end.

Common mistakes I see when opening business bank accounts

Over the years I have seen a pattern of avoidable mistakes.

One of the most common is continuing to use a personal account after incorporating a limited company. This creates director loan issues and can cause serious confusion.

Another is opening multiple accounts without purpose which fragments records.

I also see people choosing accounts with low monthly fees but high transaction charges which cost more in the long run.

Finally some people delay opening an account and then struggle to reconstruct records months later.

All of these issues are preventable with a bit of forward thinking.

Using a business bank account for tax and compliance

From an HMRC perspective a clear business bank account strengthens your position.

It makes it easier to prove income and expenses supports accurate Self Assessment and corporation tax returns and reduces the likelihood of errors that trigger enquiries.

When HMRC do ask questions having a clean bank trail often resolves matters quickly.

For VAT registered businesses a dedicated account is especially important as VAT money should be identifiable and ideally set aside.

Can I have more than one business bank account

Yes and in some cases this is sensible.

Some businesses operate:

• A main trading account
• A tax savings account
• A VAT holding account

This can help with cash flow management and prevent accidental spending of tax money.

The key is clarity. Each account should have a defined purpose and be properly recorded in your accounts.

What happens if I change banks later

Changing business banks is possible and sometimes advisable.

If fees increase service declines or your business outgrows the account switching can be beneficial.

When switching you should:

• Update customers with new details
• Update HMRC and software links
• Keep old accounts open until all transactions clear

Planning the transition avoids missed payments and confusion.

How a business bank account supports growth

As your business grows your bank account becomes more than a place to store money.

It becomes a record of performance that lenders investors and partners look at.

Clean consistent banking history supports:

• Loan applications
• Mortgage assessments for directors
• Business valuations
• Investor confidence

This is why setting it up properly early has long term benefits beyond compliance.

Final thoughts

Setting up a business bank account is not just about compliance or ticking a box. It is about creating a strong financial foundation for your business.

From my experience businesses that separate finances early understand their numbers better make fewer mistakes and grow with more confidence.

Whether you are just starting out or formalising an existing operation the right business bank account will save time reduce stress and support better decision making.

If you treat it as part of your business strategy rather than an admin chore you will feel the benefit for years to come.
