Triodos Bank Cash ISA reviews (3818)

Ethical, trustworthy and very helpful.

I'm just glad that there is a place I can out my savings which I know is going to be ethically invested. I know there are other options out there, but I chose triodos when there were a lot fewer options available, and they have always been very clear and easy to understand and have also always been helpful when I have needed help with using their online account.

THIS ISA IS A SOUND IDEA!

THIS ISA IS A SOUND IDEA. ITS INSTA NT ACCESS. Would be an even greater idea if higher tier bands of interest for giving 30-60-90-180days notice &/or if No Annual Withdrawal &/or Cumulative Years of No Withdrawal(s) Reviewed on: 16th April 2026

Trustworthy, transparent policies and values

I have always found I can get help on the phone if I really need it. I trust the values of Triodos and the openness with which they share what our money is doing in the world. Reviewed on: 16th April 2026

A breath of fresh air

I’ve had an account with Triodos for many years. They’ve always been very transparent and upfront about where your money goes. No hidden extras. So refreshing to have an ethical choice in terms of finance. Over the years the products have greatly improved, with plenty of choice. Reviewed on: 16th April 2026

First Rate Etical bank

Communication about the type of projects that Triodos supports is excellent. The ethical philosophy of the bank is far better than any other I have come across. With so much bad news in the world it is comforting to know that my savings are not supporting those who take advantage of those in difficult circumstances for their own profit.
