How to switch business bank accounts: a step-by-step guide

Switching your business bank account used to be a headache. Now, with the UK’s Current Account Switch Service (CASS), it’s a straightforward process designed to minimise disruption and give you confidence that nothing will be missed.

For sole traders and small businesses, this matters. Your bank account is the hub of your operations. Invoices, payroll, supplier payments, HMRC returns – everything flows through it. So, when it’s time to move to a provider that better suits your needs, you want the transition to be smooth and secure.

Why switch business bank accounts?

The most common reasons for wanting to leave your existing account include:

• High fees or hidden charges
• Poor or unresponsive customer service
• Limited digital tools or outdated features
• Difficulty managing cash flow or accessing credit

If you’ve ever thought your bank is adding friction instead of helping your business grow, it might be time to consider a change.

How the Current Account Switch Service works

CASS takes care of the heavy lifting. It's free to use, backed by most UK banks and comes with a guarantee:

• The entire switch is completed within seven working days
• All direct debits, standing orders and incoming payments are automatically transferred
• Any payments accidentally sent to your old account are redirected for three years
• Your balance is moved across on the final day of the switch

This means you don’t need to manually chase every supplier or customer. The process is designed to keep your business running as usual, without disruption to your cash flow.

Steps to prepare for a switch

Although CASS handles most of the process, a little preparation can make things even easier:

1. Review your current banking needs – Think about fees, features and support.
2. Choose your new account – Compare providers and find the best fit.
3. Gather documents – Proof of ID and proof of address and business details (Companies House registration for limited companies, or HMRC registration for sole traders).
4. Apply for your new account – Once approved, request to switch using CASS.
5. Check communications – Your new bank will confirm the switch date and keep you posted on progress.
