The best bank ever!

I am absolutely delighted with Triodos. I have kept my children's savings there since they were born as well as any money I was able to save in a Cash ISA. They are great at communicating where my money goes, which is very important to me. I have rarely needed to contact them, but the app is fantastic and their team are always wonderful if I do need to call. Reviewed on: 20th April 2026
