Review of the Triodos Bank, Cash ISA:

A bank that doesn't invest in fossil fuels

I love that this bank doesn't invest in fossil fuels, what a powerful way of looking after the environment! Great app and customer service too Reviewed on: 15th April 2025

I know that the money in my Cash ISA is being used for socially and environmentally important projects. This is more important to me than getting higher interest rates at the cost of ethical integrity - but the interest rates are quite competitive too. Reviewed on: 11th April 2025

There's always a real and helpful person at the end of the phone line, which is answered promptly. And it's an impressively ethical bank. Reviewed on: 11th April 2025
