Triodos Bank Cash ISA reviews (2932)

A truly ethical bank

5
Prompt customer service, but mainly it's about its genuine ethical standpoint. Reviewed on: 27th February 2021

Excellent service linked with ethical use of funds

5
It is great to know that my invested money is being used for positive change rather than risking it being used to support harmful causes such as the arms trade and destruction of the planet. Trios is also transparent in where money is invested, produces regular informative reports which stress the support of small businesses and innovative projects. They provide a reliable and efficient service which feels genuinely personal even though face to face contact is not possible. Reviewed on: 27th February 2021

Ethical banking

Triodos offer convenient online banking but it is their ethical and environmental policies which make them a stand out bank for me. If this was the template for the majority of banking the world would be a very much better place. Reviewed on: 27th February 2021

It's not got the highest interest rate out there but I like knowing that my savings are having a positive impact on the world which far outweighs that. Reviewed on: 27th February 2021

Just, not greedy, returns for using your cash to support initiatives which benefit social enterprise, entrepreneurship, ecology, in short a just and working society. Reviewed on: 27th February 2021

Outstanding - clarity and social purpose

Wonderful to know that my money is being used for good, ethical purposes. Excellent communication - and it all builds confidence that my hard-won savings are safe as well as well used in a Triodos account. Have wholeheartedly recommended it to friends. Reviewed on: 27th February 2021

Ethical investments

With Triodos you know that you’re money is being used for worthwhile investments. They are clear about what they invest in - I don’t know any other banks that are as transparent. And the rates aren’t much lower than less ethical banks. Reviewed on: 27th February 2021
