Review of the Triodos Bank, Cash ISA:

All round excellence from Triodos Bank.

The online system is straightforward and easy to use. When I have needed to speak to members of staff, they always have been exemplary. Efficient, helpful, gracious and knowledgable. Reviewed on: 30th January 2024

Triodos has always been very transparent with how the money is invested and what projects is supporting which aligns with my values. I'd rather put my money into somewhere that will make a positive impact in the world we all share. Reviewed on: 22nd April 2025

i consider triodos to be the most ethical

i consider triodos to be the most ethical and save with them - interest rates can be lower than other building societies, but thats not the point, they are the most ethical so i support them...its a pity there is a monthly charge for a current account, regardless of income or i would switch my current to triodos, but as i am on a small pension i bank elsewhere for current account Reviewed on: 22nd April 2025

Great ISA at Triodos - easy to switch

It was very easy and quick to move my ISA to Triodos last summer. It's been accumulating interest (better than my previous provider). The app is simple to use and keeps me informed. I can wholeheartedly recommend Triodos ISA. Reviewed on: 22nd April 2025

Whenever I have had a problem or question I have had personal and friendly and personal support on the phone or by email. Reviewed on: 22nd April 2025

Triodos goes the extra mile.

Triodos is the only bank I have used (the others are Lloyds; the Co-op; Nationwide), which gave me lots of information, up front, in the form of a special guide, about bank fraud and how to protect myslef against it, at a time when the other banks were not being at all proactive. I really valued it. I appreciate Triodos being transparent about how it invests our money. I haven't got a clue about how my money is invested with the other banks I use/have used.
