Savings with a conscience

I've had my ISAs at Triodos for a few years now, and I have to say that I feel better keeping my savings someplace that is ethical, and they are transparent about where the investments go and the people and orgnanisations that benefit. Reviewed on: 26th February 2021

Great all rounder

Easy to open account. When I opened it it had a great interest rate (obviously now, as with all banks, that interest rate has plummeted). Love where they invest their money Reviewed on: 26th February 2021
