Financial return with ethical assurance.

I have held a cash ISA with Triodos for several years. I could perhaps get slightly more income elsewhere but Triodos adds serious ethical dimension. Reviewed on: 16th January 2024

Fantastic bank with values, transparency and great customer service!! Reviewed on: 16th January 2024

Cash ISA transfer from another provider

Transferring my cash ISA from another provider to a Triodos Ethical Cash ISA was straightforward, with clear instructions on the Triodos Website, which was really helpful. Reviewed on: 16th January 2024

So user friendly

Always spoken to friendly helpful people, reasonably easy to use website and app. I am particularly encouraged that my savings are used ethically Reviewed on: 16th January 2024

Triodos supports people and planet

I love feeling that I am supporting projects that make the world a better place by banking with Triodos. It’s a great change to other banks who fund fossil fuels and other projects which damage the natural world. Triodos invest in people and planet, and that’s why I bank with them.

Triodos is great for Ethical investments & savings.

I use Triodos for Ethical investments & savings. Interest rates are good & I trust that my money is being put towards good causes. Access is easy as can be managed online, but customer service is great if you need to talk to a person. Reviewed on: 16th January 2024

Can't fault Triodos.

Can't fault Triodos. Staff are really friendly and helpful on the extremely rare occasion I need to deal with something that I can't purely by using the website on my own. Ethical practices are brilliant and customers are kept informed exactly where our money is being invested by occasional newsletters, which I actually read and find interesting! (Can't be said of some others I get sent.) Can't recommend highly enough. Reviewed on: 16th January 2024

The values of Triodos

The values of Triodos are similar to mine regarding its investment in companies with sound ESG. Reviewed on: 16th January 2024
