Review of the Triodos Bank, Cash ISA:

most ethical!

i am really happy with triodos and wouldnt invest anywhere else as i find them the most ethical bank! 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

Great bank

Triodos is an ethical bank with great customer service Reviewed on: 26th February 2021

A truly ethical company

As the title says, with an excellent and user-friendly website, essential for an online bank, and very helpful and accessible staff if you have to contact them by phone. I hope it stays this way. Reviewed on: 26th February 2021

Ethical banking with easy access

I have had a Triodos Online Cash ISA for some years - I love their policy of investing in social enterprise, and it's easy to log on and check my balance, as well as to withdraw money occasionally. Reviewed on: 26th February 2021

Looking forward

The bank offer a set of opportunities for getting your banking services while dedicating the resources to support real people and projects with a social and environmental impact. This is not an approach to be fashionable. It has been their practice for many years in a consistent basis. Reviewed on: 26th February 2021

Feel good banking

I like being part of a bank that fully informs you of where money is invested. Reviewed on: 26th February 2021
