LIMITED COMPANY Requirement

Limited companies must use a business account

As a limited company, you must keep company finances separate from your personal money. Using a personal account for company transactions can lead to:

  • Director's loan account issues with HMRC
  • Problems proving legitimate business expenses
  • Potential accusations of piercing the corporate veil

Open your business account before you start trading.

Comparison to other structures:

Sole traders can legally use a personal account (though it's not recommended). Limited companies cannot - company money belongs to the company, not you personally.

When this matters: Before you start trading. Banks may take 1-2 weeks to verify company details with Companies House.

What you need to open an account

Banks need to verify your identity, address, and business details. Gather these documents before you apply:

Personal ID
Passport or UK driving licence for all directors/partners/owners
Proof of address
Utility bill, bank statement, or council tax bill dated within last 3 months
Company details (limited companies)
Company registration number, registered address, details of shareholders owning 25%+
Business details (sole traders)
Trading name (if different from your name), description of what you do, expected turnover

Choosing the right account

Compare accounts based on your business needs:

Monthly fees
£0-30/month. Some accounts are free for the first year or permanently free with limited transactions.
Transaction limits
Free accounts often cap transactions. Check if the limit covers your expected activity.
Accounting integration
Direct feeds to Xero, QuickBooks, FreeAgent save hours on bookkeeping.
Card payments
If taking card payments, check merchant services fees and integration.
Overdraft facility
Useful for managing cash flow gaps. Compare rates and arrangement fees.

The application process

Most banks let you apply online. The process typically takes:

  • Online applications: 10-30 minutes to complete, decision within 1-5 working days
  • In-branch appointments: 30-60 minutes, often same-day approval
  • Complex businesses: 2-4 weeks if the bank needs additional checks (high-risk sectors, overseas connections)

Some banks offer instant account numbers for online applications, letting you start receiving payments immediately while full verification completes.

SOLE TRADER Advantage

Sole traders can open accounts faster

As a sole trader, you can often open a business account within 24 hours because:

  • No Companies House checks needed
  • Simpler ownership structure to verify
  • Some banks offer instant digital account setup

Many challenger banks (Starling, Tide, Mettle) specialise in quick sole trader account opening.

Comparison to other structures:

Limited companies and LLPs need Companies House verification, which can add days to the process.

When this matters: When you need to accept payments quickly or want a simple account setup process.
