The most ethical bank

I really appreciate the ethical standards of Triodos Bank and their transparent communications. I feel my money is in good hands with them, and this is at least as important as interest rates. I find the online banking easy to use and their customer service has always been very responsive and helpful when I have contacted them. I would recommend Triodos Bank to anyone looking for an ethical bank and peace of mind knowing their money will do some good. Reviewed on: 23rd January 2026
