Triodos Bank Cash ISA reviews (2680)

The main thing for me is that the bank is totally ethical, not supporting harmful stuff, like arms or drugs or cigarettes

The service is wonderful. They are very good when I phone them. Reviewed on: 15th January 2022

No nonsense, honest and ethical banking.

No jargon with Triodos - clear indication of their values and ambitions to bank for the good of all. Ethical banking as it should be. Reviewed on: 15th January 2022

The most ethical Ida I could find

After Triodos modernised their online banking it made it easier now than ever to bank with them. Before it was just to get an ethical bank, now they’re more relevant as a solid modern bank. Reviewed on: 15th January 2022

So good to know!

It is so good to know my savings are being used for ethical purposeful ventures. Reviewed on: 15th January 2022

Best bank by far

I've been with Triodos for many years, my initial motivation being their ethical stance and values. That remains important to me but I have also valued clear communication, responsiveness and helpfulness when I have had queries and simple friendliness Reviewed on: 15th January 2022

Amazing service and rates

Since joining I have experienced the best service I’ve ever had from a bank. Clear communication, fast response and generally great, friendly service. Also, can t is fantastic to get a good rate with money that I can trust is being used for sustainable and ethic things. Reviewed on: 15th January 2022

Unexpectedly, I have money to save. This is the only bank I want to use for this, to uphold my ethical stance

I am not brilliant with online banking, but if I need to speak to someone that is easy, helpful, and just right! Thank you. Reviewed on: 15th January 2022

Best ethical bank

Feel safe in the knowledge that my money is protected and going towards ethical investments which will benefit the environment and wider community, unlike the majority of high street banks which are not as transparent as Triodos so you can never be quite certain whose pockets your money is going in to. I feel trust in Triodos that they are doing the right things with my investment. Reviewed on: 15th January 2022

A beautiful bank with a mission.

Triodos gives a good service and supports many small enterprises that work for the good. I think this bank deserves an award as it has stuck to its principles. Reviewed on: 15th January 2022

Ethical banking is needed

This bank offers the only ethical banking service in the UK. I thank you. I don't understand how this is not the norm Reviewed on: 15th January 2022
