Efficient and ethical

I have absolutely no complaints about Triodos Bank. I have been a happy customer for a number of years now and i would like to see ethical banking become more and more normal. Reviewed on: 26th February 2021

I know my savings are helping the world be a better place

I choose to save with the Triodos bank, because I know my money is only being used ethical projects. I love receiving their newsletter and reading about all the different projects that are being helped. It makes me feel there is hope and that at community level wonderful things are happening. That Triodos Bank also invests in renewable energy is also makes me feel positive. I wish all banks would think about their money goes as they could make such a difference to the future Reviewed on: 26th February 2021

Ethical ISA

The customer service I have received from Triodos has always good, and it feels so much better to know that my money is being used to invest in and support ethical businesses who are making a difference for good in the world. Reviewed on: 26th February 2021

Ethical savings

Good to know one’s retirement savings are as ethical as possible Reviewed on: 26th February 2021

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. Reviewed on: 26th February 2021

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! Reviewed on: 26th February 2021

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
