Polar Business Banking Guide
Business bank account UK — choose an account that keeps business money clear and controlled.
Understand when a separate account is needed, compare banks and digital providers, check charges and protection, and prepare the information required to open a UK business bank account.
Who needs a business account?
Start with the legal structure of the business.
A limited company is legally separate from its directors and shareholders. GOV.UK says company banking must be kept separate from personal banking, with a business bank account being the simplest way to create that division.
Sole traders and ordinary partnerships are not normally legally required to have a business account. However, some personal-account terms do not permit business transactions, so check with the bank before using one. A separate account also makes bookkeeping and tax preparation much clearer.
Whatever the structure, use an account in the correct legal or trading name and keep reliable records of money received, money paid, expenses, taxes and transfers to or from the owner.
Do not choose an account on a free introductory period alone.
Consider what it will cost and how it will work once the offer ends and the business is handling real customers, payments and suppliers.
Business account comparison
Eight practical features matter more than a long benefits list.
Think about how money will actually enter, leave and be reviewed inside the business.
Monthly and transaction fees
Compare the regular fee, electronic payments, cash deposits, international transfers, cards and charges after any introductory period.
Cash and cheque handling
If customers pay in cash or cheques, check where deposits can be made, how long they take and what each deposit costs.
Accounting connection
Reliable bank feeds, exports and integrations can reduce manual entry and help keep the accounts current.
Cards and spending controls
Consider additional cards, individual limits, receipt capture and the ability to freeze a card quickly.
Multiple-user access
Accountants, bookkeepers and staff may need controlled access without sharing the owner’s login details.
Payments and approvals
Check payment limits, bulk payments, Direct Debits and whether larger payments can require two people to approve them.
Borrowing and overdrafts
If short-term credit may be needed, understand eligibility, guarantees, interest, charges and whether lending is available at all.
Support and resilience
Look at support hours, emergency card help, service status information and what happens if the app or internet connection is unavailable.
Opening the account
Prepare the business information before applying.
Every provider sets its own eligibility and verification requirements. Having consistent information ready can prevent avoidable delays.
A bank may also ask where startup money came from, who owns or controls the business, expected countries and currencies, typical customers and suppliers, and why the account is needed.
Identity and home addressEvidence for directors, partners, owners or other people who control the account.
Business identityLegal name, trading name, business address, contact details and start date.
Company informationFor a limited company: company number, incorporation details, registered office and director information.
Business activityA clear description of what the business sells, who it serves and how it expects to trade.
Financial expectationsForecast turnover, transaction volumes, tax details, funding and existing borrowing where requested.
Protection and authorisation
Check who actually holds the money and what protection applies.
The Financial Services Compensation Scheme says eligible company deposits with a UK-authorised bank, building society or credit union can be protected up to £120,000 per eligible company depositor per authorised firm.
For a sole trader, personal and business deposits held within the same banking group are generally combined when the protection limit is calculated. A limited company is a separate legal entity and may have its own protection, subject to FSCS eligibility.
E-money and payment firms may safeguard funds instead of providing FSCS deposit protection. Check the provider using the FCA Firm Checker and confirm the protection directly rather than relying on branding or app-store wording.
Using the account well
Build simple money controls from the first customer payment.
01
Keep business money separate
Pay business income and costs through the business account rather than mixing transactions across several personal accounts.
02
Reconcile regularly
Match the bank to invoices, bills, receipts and accounting records while the transactions are still easy to recognise.
03
Reserve money for tax
Use a separate pot or savings account where suitable so tax, VAT and payroll money is not mistaken for available cash.
04
Control user access
Give each person their own access and permissions. Do not share the main password between directors, staff or advisers.
05
Review charges
Check fees and account suitability when transaction volumes, cash handling, overseas work or staffing changes.
06
Keep statements and records
Download and retain the records needed for bookkeeping, tax, funding applications and future account switching.
Switching accounts
A business account does not have to be permanent.
The Current Account Switch Service can move eligible UK business current accounts between participating providers, normally within seven working days.
Before switching, confirm eligibility, download historic statements, review any borrowing or card arrangements and tell payment services or important customers if details outside the switch need updating.

Five account decisions that can create unnecessary work later.
A free period is useful, but ongoing fees and practical features matter for much longer.
It weakens records, complicates bookkeeping and can blur responsibility for the company’s money.
Check the legal provider, regulatory permissions and whether protection is FSCS or safeguarding.
Use named users and suitable permissions so activity can be controlled and audited.
The right startup account may become expensive or restrictive as payments, staff and international activity grow.

Business bank account FAQs
Opening and using a UK business bank account: common questions.
Do I need a business bank account as a sole trader?
A UK sole trader is not normally legally required to have a separate business bank account, but the terms of a personal account may prohibit business use. A dedicated account also makes bookkeeping, tax preparation and cash-flow tracking clearer.
Does a limited company need a separate business bank account?
A limited company is a separate legal entity. GOV.UK says there must be a clear division between company finances and the personal finances of owners and directors, and that company banking must be separate from personal banking.
What documents are needed to open a UK business bank account?
Requirements vary, but providers commonly ask for identity and address evidence, business and trading names, business address, activity and expected turnover. Limited companies may also need incorporation details, the company number, registered address and director information.
Are business bank accounts protected by FSCS?
Eligible company deposits with a UK-authorised bank, building society or credit union may be protected by FSCS up to £120,000 per eligible company depositor per authorised firm. Sole-trader business and personal deposits at the same banking group are generally combined for the limit. Check the provider and your eligibility directly with FSCS.
Is an e-money business account the same as a bank account?
Not necessarily. Some payment and e-money firms safeguard customer money rather than protecting deposits through FSCS. Check the provider’s regulatory status, how funds are protected and whether the product meets the business’s needs before applying.
Can I switch business bank accounts?
Eligible small businesses can use the Current Account Switch Service when both providers participate. The service normally completes the switch in seven working days and transfers regular incoming and outgoing payments.
