Triodos Bank Cash ISA reviews (2925)

My money doing good things

5
I am proud to have savings in a Triodos cash ISA because I know that it is invested in progressive activities that help to build a better and more sustainable world for generations to come. What Triodos invests in is clear and transparent and they communicate examples of projects and businesses that this investment is supporting. It is not just about making money - it is about a better life for people now and in the longer term. It is about creating lasting value for many. Reviewed on: 14th February 2021

Ethical Banking with substantial customer rewards

4
I am convinced that Triodos have the most ethical policies for banking. I use an ISA on-line savings account, which has an excellent interest rate for long-term investment. Although it is managed on-line, I have found the telephone banking customer services to be first rate. Reviewed on: 14th February 2021

Best for me, best for my children's future

5
I love the way Triodos puts ethics first, without compromising on value. The interest rates I get for my ISA are better than or comparable to the big banks, and I know that my money is being put toward a better future for my children, not a worse one. Now all we need is for the rest of the banking sector to follow this model. Reviewed on: 9th February 2020

This bank does good for all. How banks should have evolved . If they had then maybe the 2008 banking crisis wouldn't have happened? Reviewed on: 9th February 2020
