Cynergy Bank Business Savings Review: My Verdict

Overall, I see the Cynergy Bank Business Savings Account as a great all-rounder offering customers an attractive interest rate, zero account fees, and easy access to their money.  

The 3.65% AER interest rate is competitive for an easy-access account, allowing you to maximise growth and make deposits or withdrawals whenever you want. 

I think where Cynergy really excels is the flexibility of their savings account. A low minimum balance requirement of £1 combined with no monthly fees means that the Business Saver Account suits customers with a variable cash flow. 

However, the lack of a mobile banking app or physical branches may make regular account management inconvenient.
