Review of the Triodos Bank, Cash ISA:

Ethical, informative, accessible, helpful and unique.

Ethical, gives lots of information about their projects, easy to manage apps, useful alerts, the best one of its kind. Reviewed on: 23rd April 2025

Triodos gave me confidence with money movements

A family member of mine died, resulting in the first time I had £10 000 to look after and so I thought an ethical ISA was a good place to put it while I figure out my life and do university assignments. Triodos made it easy to set up my cash ISA. They have an app that I can check, and I like reading the stories they post there. Money is transferred quickly, and information is repeatedly very easy to find about my account, making it very easy to use and reference Reviewed on: 17th January 2024

More ethical than any others.

Properly ethical banking. All excellent except the need to calculate interest January to December because of accounting period not being same as Inland Revenue. Reviewed on: 17th January 2024

Have confidence in investment choices

Triodos Bank is one of the few places where I feel confident that my money is not invested in things which are bad for society and, moreover is typically invested in projects which are good for society and for the planet. Reviewed on: 17th January 2024

Gold standard for ethical investment.

Gold standard for ethical investment. Transparent about everything as banks should be, Triodos tell you exactly what your money is supporting. The app is simple to use with educational newsletters all the time. Reviewed on: 17th January 2024

The green credentials of the Triodos bank are well d...

The green credentials of the Triodos bank are well deserved. The world needs more not less green investment. Caring for those less fortunate is Akila a worthy additional feature and the focus on decent humane principles should be applauded. So many companies run on callous self interests rather than the values and principles of fairness and transparency demonstrated by Triodos. The trust feels real with this bank. I’m proud to be a customer Reviewed on: 17th January 2024

Triodos made it easy

Triodos made it easy to make a choice about ISAs that fit with my values whilst providing me with a good return, and then to act on that decision. I will definitely be using them for more banking in the future. Reviewed on: 17th January 2024

Ethical banking at its best!

A great, feel-good bank which offers flexibility, great ethics and super customer service. Reviewed on: 17th January 2024
