Review of the Triodos Bank, Cash ISA:

Ethical banking

We feel very happy to bank with Triodos knowing that our money is going towards an ethical, environmentally friendly future. Reviewed on: 7th April 2023

Ethical ISA

I couldn't be happier with my experience with Triodos Reviewed on: 3rd March 2021

Money invested used for ethical investment

An excellent organisation which engages with customers and keeps them fully informed about its activities. A force for good in our society! Reviewed on: 3rd March 2021

Ethical Banking

If people knew what banks are spending their money on they would all switch to 'ethical' banking! I love knowing that the money I am saving is working for good. Reviewed on: 3rd March 2021

Truly ethical investment

Investing with Triodos brings me peace of mind because I can be confident that my investments will not harm nature and human rights, in fact they benefit them. The term 'ethical investment' is often used these days but when I've looked at the underlying investments in certain stewardship funds, I've found that they aren't at all aligned with my personal ethics. That Is why moved to Triodos Bank. Reviewed on: 3rd March 2021

Brilliant

The only way trios could be any better would be through becoming the benchmark other banks had to live up to Reviewed on: 3rd March 2021

Ease of use and peace of mind....

Both myself and my daughter have ethical cash isa’s. I wanted savings accounts which I felt were contributing to something bigger and better than the high street banks had to offer. In all my dealings with Triodus they have been amazing, the accounts are easy to use and I feel good about choosing them. Reviewed on: 2nd March 2021

How we use our money is everything.

I’m only interested in using companies that have their priorities in order, and Triodos fits that description. Reviewed on: 2nd March 2021

Transparency lets the light in...

We all know that we don't know what is really going on behind closed doors. Internet trolls hide through their anonymity. Triodos let you see what they are using your money for, leaving you in a position to support this or not. But just the fact that this is public information means that they take a principalled decision about what they are doing. Reviewed on: 2nd March 2021

Triodos meets my needs!

I am very happy to have a bank I can trust to deal ethically with the money I have saved with them. Triodos communicate updates to their service and changes to interest rates by email. I find their on line account very convenient and easy to manage 24/7. Reviewed on: 2nd March 2021

Ethical investment is vital to combat the Climat Crisis and support Fairtrade farmers

I've worked for a total of 8 years in 3 African countries and I've seen the great needs for access to capitalto enable self development. Reviewed on: 2nd March 2021
