A genuinely ethical bank

It's deeply refreshing to see a genuinely ethical bank in a marketplace dominated by funders of the least ethical business practices. I'm very glad to be a customer of Triodos. Reviewed on: 24th March 2026

Easy to use bank.

Easy to use bank. Doesn’t bother me with constant irrelevant advertising. Reviewed on: 24th March 2026

Honest, ethical and a good product

Triodos aligns very closely with my personal values by putting sustainability, transparency and positive impact at the centre of its decisions. Its rates are competitive and Triodos is very easy to deal with, although I have hardly had to do this in the many years I have been with Triodos. Reviewed on: 24th March 2026

Good job!

It’s been a pleasure to have Triodos as my bank and I especially respect their ethical values. Reviewed on: 24th March 2026

An investment that helps the world

It's great to know my cash ISA is making a contribution to tackling, rather than perpetuating many of the world's biggest problems. Furthermore, setting up a cash ISA was easy and I really like how Triodos keep me informed of deadlines for any further deposits. Reviewed on: 24th March 2026
