Believable

The first time I have trusted a bank. My first job in the 60’s was in banking in London and I soon learnt that none of them were trustworthy Reviewed on: 17th April 2021

long term client

I have had two ISA's with Triodos for many years. They don' t yield top dividends but I have them not so much for my own benefit as to contribute to the principals and projects of Truidos bank. Reviewed on: 17th April 2021

Use your savings to do good

Fabulous ethical & transparent banking. I love that Triodos is investing my savings in projects that put people & planet first, whilst offering comparable return on my savings. It’s great to hear about the projects they are supporting and ethical news articles. Reviewed on: 17th April 2021

A bank focused on changing the world

I was lucky enough to inherit some money when my uncle died and I really wanted to make sure the investments I made with it would do some good in the world. I have confidence Triodos has allowed me to do this. Plus their customer service is fab! Reviewed on: 17th April 2021

Great to invest ethically Ki

I have two ethical issues with Trimdon. As with all savings the returns are very poor at present. But I have the satisfaction of knowing my investment is used wisely for greater good. Reviewed on: 17th April 2021

Easy saving with a clear conscience

Very easy website, customer service is always really good, regular updates on the ethical investments and good returns. Reviewed on: 17th April 2021

All banks should adopt the ethical principles of Triodos - a true leader!

Very pleased with the transparency of knowing where my money is invested - and approving! Reviewed on: 17th April 2021
