Triodos Bank Cash ISA reviews (2679)

Ethical and transparent

I have had a cash ISA with Triodos for many years; although the interest rate is low at the moment it's better than some options. But more importantly Triodos keeps customers informed about exactly what they are doing with our money, and they invest ethically and sustainably in causes I am very happy to support.

Triodos will save us all!

It is such a relief for my conscience that Triodos can offer a more ethical banking solution. I think we desperately need to move away from an exploitative and violent investment paradigm and Triodos is leading the way to realising a world built on respect for all life. Thank you Triodos!

Easy to manage and feels a great choice for the future

When I wanted to open a savings account for my little boy there was no other choice than Triodos. I want him to know from an early age that money can be used for good. Reviewed on: 26th February 2021

Great Ethical Banks

Transparent and lend to sustainable companies - keep it up, a great bank! Reviewed on: 26th February 2021

I know my money is being put to good use

Easy to check on the account with online banking and regular updates about companies that the bank has funded. Much higher ethical credentials than other banks, even Co-op. Reviewed on: 26th February 2021

What our planet needs

Ethical banking when and where the world needs it most. Triodos is a bank that appreciates we all share the same planet, a bank that supports projects and business that supports us all. I appreciate transparency and human-sized values of Triodos. Reviewed on: 26th February 2021

Respectful

Easy to cask with, pragmatic but wish app possible Reviewed on: 26th February 2021

Go to prioritise ethical investment over profit

As well as being ethical, Triodos is also very collaborative, efficient in administering accounts and keep savers like me well informed. Reviewed on: 26th February 2021

Easy no fuss ISA with excellent customer service

Triodos always keeps its customers well informed and of course only invests in ethical projects. This feels like real people dealing with real people without the fuss of faceless nameless interactions. Reviewed on: 26th February 2021

Excellent information and research

The Bank provides excellent information to its customers about their ethical investments. They provide first hand accounts from their funded projects, which is informative, interesting and fun to read. Reviewed on: 26th February 2021
