Excellent app and ISA service

Excellent app and ISA service, I have paid money into my ISA and due to circumstance, had to withdraw too, this has been very easy to do and straightforward! A very clear and easy to use app! Reviewed on: 3rd February 2026

The banking model for the 21st century

The bank is professional, always helpful and simply the banking model for the 21st century. They also go that extra mile to provide information on how every penny of money invested in the bank is spent. That is heartwarming and rewarding in an era of impersonal machine like banking. Reviewed on: 3rd February 2026

Excellent Ethical Bank

At last I’ve found a bank that has similar principles to mine. A bank that wants to help people and the world not destroy it. Reviewed on: 2nd February 2026

Easy to set up and a great rate with a clear conscience

Easy to set up and transferred the funds from one ISA to a new one to get a better rate but still using ethical investment principles Reviewed on: 2nd February 2026

Most importantly aligned with my values.

Easy to use, friendly service, and most importantly aligned with my values. I care deeply about the environment, and living in a society that cares for it's most vulnerable members, and this is what Triodos does. Reviewed on: 2nd February 2026
