The best way to invest your money 'greenly'

4
As someone looking to invest in a cash ISA but also wanting to avoid putting my money somewhere that might invest in areas I don't want to support (fossil fuels, arms, tobacco, etc.), Triodos was by some distance the best choice. I'm very happy to have done this. Reviewed on: 26th February 2021

It is possible to invest in a way that helps others. That's important.

I feel confident that not only is my money not doing harm, but that it is doing good. I don't have a lot of money, but what I do have, I want to make sure is being used as a force for good. I think that should be the minimum requirement for all investment, and hope for a future when that is the norm, and not unusual. In the meantime, Triodos is leading the way, and in a small way, it helps create a feeling of connection to others. Reviewed on: 26th February 2021

Ethical, informative, local and no problem. Worth the minute difference in interest rates compared with those of bigger banks. Reviewed on: 26th February 2021

Triodos Cash ISA

If you want somewhere to store your money more responsibly for yourself, Triodos' ISA is the place to go. Such a good product and I'm so glad I have one to save for my future whilst being reassured that Triodos are investing my money safely, ethically, and with community and environmental impetus.
