Review of the Triodos Bank, Cash ISA:

Ethical banking at its best.

Ethical banking at its best.Would recommend to everyone. Reviewed on: 16th January 2024

Why help the bad guys?

There are higher interest rates available, but its not easy to avoid funding torture, tax-avoiders, and bad employers. Triodos is the answer, publishing lists of all those they fund, and having policies on what they WONT fund. The bank is very easy to deal with (forgot password, got human on phone straight away, friendly, helpful, didnt make me feel like an idiot). Even if they aren’t your main bank, investing something with Triodos pushes the financial world a little in the right direction, without risking your money. Reviewed on: 26th February 2021

Fantastic

Very easy to use bank and very ethical - supporting the needs of people and planet. Reviewed on: 26th February 2021

Amazing value and customer-driven service

Triodos is the only bank which is truly value-led, with the health of our society and our planet at its core. They also do this with brilliant customer support, a range of banking options, and I love reading their magazine which they send to all their customers and which is very inspiring - all the amazing initiatives the bank is supporting. I don't know why everyone doesn't bank with Triodos - let's bank for a better future! Reviewed on: 26th February 2021

Efficient and ethical

I have absolutely no complaints about Triodos Bank. I have been a happy customer for a number of years now and i would like to see ethical banking become more and more normal. Reviewed on: 26th February 2021

I know my savings are helping the world be a better place

I choose to save with the Triodos bank, because I know my money is only being used ethical projects. I love receiving their newsletter and reading about all the different projects that are being helped. It makes me feel there is hope and that at community level wonderful things are happening. That Triodos Bank also invests in renewable energy is also makes me feel positive. I wish all banks would think about their money goes as they could make such a difference to the future Reviewed on: 26th February 2021

Ethical ISA

The customer service I have received from Triodos has always good, and it feels so much better to know that my money is being used to invest in and support ethical businesses who are making a difference for good in the world. Reviewed on: 26th February 2021

Ethical savings

Good to know one’s retirement savings are as ethical as possible Reviewed on: 26th February 2021

Ethical and transparent

I have had a cash ISA with Triodos for many years; although the interest rate is low at the moment it's better than some options. But more importantly Triodos keeps customers informed about exactly what they are doing with our money, and they invest ethically and sustainably in causes I am very happy to support.
