Opening a business bank account in the UK can involve more checks than a personal account. Banks need to understand who owns the business, what it does, where the money comes from and who has authority to operate the account.
Whether you are a sole trader, limited company, partnership or charity, preparing the right documents can help avoid delays.
Proof of identity
Banks usually ask for proof of identity for business owners, directors, partners or people with significant control.
Common documents include:
- passport
- UK driving licence
- biometric residence permit, where relevant
- share code, where relevant
- certified copy of ID, if applying remotely
The name on your ID should match your Companies House or business records.
Proof of address
You may need proof of residential address for directors, owners or signatories.
Common documents include:
- utility bill
- council tax bill
- bank statement
- mortgage statement
- tenancy agreement
- HMRC letter
- driving licence
The document usually needs to be recent and show your full name and current address.
Business details
The bank will ask for information about the business itself.
This may include:
- business name
- trading address
- registered office address
- nature of business
- expected turnover
- expected transactions
- countries you trade with
- website or online presence
- main customers and suppliers
Be clear and consistent. Vague business descriptions can lead to extra questions.
Limited company documents
If you run a limited company, the bank may check your company details against Companies House.
You may need:
- company number
- certificate of incorporation
- Companies House profile
- articles of association
- confirmation statement
- shareholder details
- director details
- persons with significant control details
Most banks can access some records directly, but they may still ask you to provide documents.
Sole trader documents
If you are a sole trader, you may need to prove your trading activity.
Useful documents include:
- HMRC self assessment registration
- unique taxpayer reference
- invoices
- client contracts
- business website
- accountant letter
- trading name evidence
- proof of business address
If your business is new, the bank may ask for a business plan or expected income.
Partnership documents
For partnerships, banks may ask for documents showing who is involved and who can operate the account.
This may include:
- partnership agreement
- partner identity documents
- partner proof of address
- HMRC registration
- business address evidence
- authority to open the account
All partners may need to complete checks.
Source of funds
Banks may ask where the money going into the account will come from. This is common for new businesses, large deposits or unusual transactions.
Source of funds evidence may include:
- savings statements
- investment records
- loan agreement
- client contracts
- invoices
- sale agreement
- grant letter
- investor documents
The bank wants to understand the origin of the money, not just the balance.
Tax and HMRC documents
Tax documents may be useful, especially for sole traders or established businesses.
You may need:
- unique taxpayer reference
- self assessment records
- VAT registration certificate
- corporation tax reference
- HMRC letters
- tax return
- accountant letter
Keep these records organised and easy to access.
Business address evidence
If your business address is different from your home address, the bank may ask for proof.
This may include:
- office lease
- coworking agreement
- utility bill
- serviced office agreement
- virtual office agreement
- business rates document
Some banks have rules about virtual offices, so check before applying.
Common mistakes to avoid
Business bank account applications are often delayed by incomplete or unclear information.
Common issues include:
- proof of address is too old
- business activity is too vague
- Companies House details are not updated
- director name does not match ID
- shareholder information is unclear
- source of funds is not explained
- business address evidence is missing
- wrong people are listed as signatories
Final thoughts
Opening a business bank account in the UK usually requires proof of identity, proof of address, business details and sometimes source of funds evidence. Limited companies may also need Companies House information, while sole traders may need HMRC and trading evidence.
Preparing your documents before applying can make the process smoother and reduce the chance of delays.
