Review of the Triodos Bank, Cash ISA:

Best ethical British Bank!

Great bank with ethical principles towards financial savings, and good service through the App which is simple to use. Interesting emails about support given to community projects rather than just asking to buy more services like other banks. Reviewed on: 10th April 2025

Great Cash ISA

I have held a Cash ISA with Triodos for a number of years and I get regular updates via the website on how it is performing. I am not looking for significant returns as I am more interested in my money doing good, but I have still been impressed with returns. Reviewed on: 22nd April 2025

The Triodos cash ISA has had a consistently strong rate of interest for some time now and I have been happy to continue saving with an ethical bank. I would like to see an easier means of using the app: it is a bit overly securitised and I would question whether the face recognition setup is really necessary. Reviewed on: 22nd April 2025

Transparent, ethical banking is very important to me as a customer and Triodos lead the way with clear, strong principles and highly informative impact reports. Reviewed on: 22nd April 2025
