I love the ethos of Triodos, banks do not have a good reputation often investing in unethical ventures and abusing their position of financial strength. Triodos is the only international bank close to creating the opposite to this paradigm. Reviewed on: 24th April 2026

Every touch point with Triodos has been positive, from opening the ISAs to dealing with customer service via chat or phone. Reviewed on: 24th April 2026

It's a great bank and I love it a lot, but the interest rate isn't high enough I don't think. Not just that, the log in process and app still feels a little funny. I think you should use Monzo's app based user experience as a model. Reviewed on: 22nd April 2026
