My money is being used ethically. I'm so happy to know that my money is being used ethically. At my age, 78, it could be difficult to bank online but I've found it relatively easy. Reviewed on: 4th February 2026

Setting up and using a Cash Isa with Triodos Bank.

5
Setting up and using a Cash Isa with Triodos was easy. Staff were very helpful from the start, which helped me make the right decision about what sort of account I needed. Subsequent communication about rates of interest etc have always been clear and informative. Although it is an online account Triodos do not send any more emails than are necessary and overloading your inbox. I would thoroughly recommend them to anyone happy to do everything on line.

A good ethical way to save.

A good ethical way to save. Triodos keep me up to date with their investments and how it benefits small farmers and ethical businesses. Also tells me about other opportunities eg wind farms which I have invested in. Reviewed on: 22nd April 2025
