Cynergy Bank Cash ISA reviews (300)

2 year fixed rate ISA

Easy to set up and maintain, and with good interest rate attached. Reviewed on: 24th March 2026

Such a great Bank.

Such a great Bank. They always inform you Off interest rates changing. I love the fact that I don’t have to go looking when the rates change. They do it for you. Nothing is kept undercover. And if they feel that you need to change they give you a suttle nudge. It is then up to you to choose. I have no hesitation to recommend this Bank to anyone. I have both ISA and savings accounts with them and both work really well. It is so easy to change from one interest rate to another. It happens in seconds with no problems, however many times you change. Reviewed on: 24th March 2026

Mine’s been a good experience with Cynergy Bank

It was very easy to open the cash ISA account online, and then manage it via Cynergy’s online banking website which is very straightforward to use and is quite ‘customer friendly.’ Reviewed on: 24th March 2026
