I chose Triodos for my fixed rate 2yr ISA because of their ethics. Really they are the best bank for ethical banking and I love the range of impact stories they have. Saving might have lower interest rates but for me that is in effect part of my charitable giving. I get less (maybe 1% lower than other banks) but know I am supporting ethical works - Reviewed on: 21st February 2026
