Cynergy Bank Cash ISA reviews (302)

Excellent interest rates and an easy bank to deal with

I have fixed and easy access cash ISAs with Cynergy and have always found their interest rates among the top paying accounts and their on-line operation easy to access and follow. I am also kept informed should they have an account with a higher interest rate and can easily update to the new account should I wish to do so. As long as they continue the good work, I am very happy to stay with Cynergy. Reviewed on: 23rd March 2026
