Triodos Bank Cash ISA reviews (2680)

Piece of mind about ethical investment

The Triodos Ethical Cash ISA is easy to use and it's great to have peace of mind that my money is invested in a way that does not harm the planet or other people. Certainly recommend. Reviewed on: 15th January 2022

The most ethical bank

The main reason I am voting for Triodos is that they are, in my opinion, the most ethical bank in terms of the business and projects they support and invest in. For me this is the most important thing that a bank can do - especially supporting sustainable and environmental projects. Reviewed on: 15th January 2022

Ethical, efficient and customer friendly!

Triodos tick all the boxes for morality and good service Reviewed on: 15th January 2022

Great performance

The ethical ISA has performed well, but much more important is knowing the money is invested for ethical sustainability Reviewed on: 15th January 2022

The original genuine ethical investor

Triodos have a long proven track record in truly ethical banking - they were investing in ecologically sound and socially beneficial projects long before it was fashionable and have remained ahead of the field ever since. Reviewed on: 15th January 2022

A brilliant bank

I have some private banking with Triodos for a good number of years. I also live in a cohousing neighbourhood which was built with a loan with very reasonable rates 10 years ago. Reviewed on: 15th January 2022

Fair, creative, lifechanging

It’s actually exciting to see how my money is put to work for the good of others. Reviewed on: 15th January 2022

A diamond in the rough

We were horrified by the scale of unethical and harmful investments by the vast majority of banks and were delighted to discover Triodos, a bank with ethics at its heart. I like hearing the updates on the positive difference Triodos makes to our planet and people. I have recommended Triodos to everyone and feel they deserve this award and are a shining example for other banks to follow. Reviewed on: 15th January 2022

A bank to be proud of

Investing with Triodos has been a great experience - they are very clear about their principles, and they offer a simple opportunity to invest in worthwhile enterprises. It's really good to read about what they are doing in "The Colour of Money" newsletter, and really good to see a bank trying to make a positive difference in the world (and not just more money for themselves). Reviewed on: 15th January 2022
