Triodos Bank Cash ISA reviews (3818)

You can trust Triodos

I have been an investor with Triodos for about twenty years. I am impressed by transparency in publicising where funds are invested; in the knowledge and understanding Triodos workers have of the projects funded; in the ethical choices for what is good and sustainable for people and for our planet. Reviewed on: 26th March 2022

The only bank you know what they do with your money

Easy to open the account and run it. Knowing the money is being used for the common good should matter to everyone and is sadly not the case with most financial institutions taking deposits. Great peace of mind that my small investment goes towards larger ethical investments. Thank you Reviewed on: 24th March 2022

A great ethical bank

I have been banking with Triodos for quite a few years and I have always been happy with their service. I have noticed quite a few improvements recently , for example the new website which things much easier. Reviewed on: 23rd March 2022

Very good bank

Good service and good ethics. Also very up to date with technology. Reviewed on: 21st March 2022

Great ethical bank which provides an excellent service

I am pleased to have been a Triodos customer for many years and can highly recommend it. Reviewed on: 20th March 2022

No worries about where my money is being used

I want my money to be used for good, but sneakily funding fracking or oil extraction. I can be sure that is so with Triodos Reviewed on: 20th March 2022

Great product

Allows me to have savings with ethics that don't keep me awake at night. Reviewed on: 17th March 2022

Thank you, Triodos!

I’m so proud to be banking with you. It’s a delight to read about all the green initiatives you’re involved in - and by extension I am too - all over the country… Reviewed on: 17th March 2022

very pleased with Triodos

Triodos feel like a company genuinely run to fulfil a purpose, to invest ethically and sustainably. Most other investment companies feel as though this is an add-on, and not core to their business goals. Reviewed on: 17th March 2022

Ethical banking made easy

I have been with Triodos since 2013 and find their accounts easy to access and their customer service is great. It's an easy way to invest your money ethically! Reviewed on: 17th March 2022
