Ethical banking

Friendly, knowledgeable and helpful staff - real people, not 'bots. Excellent and easy to use App. High street banks should be ashamed of their support of extractive and exploitative industries and Triodos proves that ethics and banking are not mutually exclusive. Reviewed on: 20th March 2026

A genuinely caring bank

I've been with Triodos for over 15 years. I was attracted to banking with them because of their fantastic ethics, helping fund projects that genuinely help less fortunate people. I love that my savings are being used to help people and projects that really need help. Their customer service is fantastic and I have recommended them to many of my friends and family.

I appreciate that Triodos leads with ethical messages.

I appreciate that Triodos leads with ethical messages. I don't want my money funding war, fossil fuels, fascism, climate change, or biodiversity loss, which most other banks actively or tacitly support. Reviewed on: 20th March 2026
