The only truly ethical choice

The only truly ethical choice, full of information about investments and projects and how they make a positive impact. Customer service is great too. The best choice for anyone wanting to avoid contribution to environmental damage. Reviewed on: 16th January 2024

Triodos - the star of ethical bankinh

It's important to me to use the most ethical bank possible and Triodos tick all the boxes. They are top of their game and I recommend them all the time to friends and family. It is of the utmost importance that banks behave responsibly and only invest with respect for all people and the planet uppermost on the agenda. We have a choice with whom we bank so please check carefully what bankers are doing with your money. With Triodos I know my money is not invested in arms, war or anything contributing to climate breakdown. Green and clean, thank you Triodos! Reviewed on: 16th January 2024

The best socially responsible bank

High interest rates provide a good return every 6 months. The online app is easy to use and money can be transferred quickly to my current account with a different bank. I also love knowing that money money is helping socially responsible businesses. Reviewed on: 16th January 2024

Only ethical bank: Got to be a winner. There is so much more to consider than money. Reviewed on: 16th January 2024

A very safe & sound harbour in today's world.

Excellent customer service and very prompt transactions. Above all, Triodos Bank is ethically & environmentally very sound & committed. I would recommend them highly to my friends, families & colleagues. Reviewed on: 16th January 2024

Good banking in more ways than one

I was horrified when I discovered my old bank HSBC, and several others on the High Street are were funding climate devastation. I looked for an ethical alternative. Triodos more than fulfilled the remit. BTW, those other banks are now funding literal genocide, which puts our privileged concerns about customer service into stark perspective.

Informative and helpful.

Informative and helpful. Positives and risks of options explained. Ethical benefits clearly promoted. Reviewed on: 16th January 2024

Customer facing staff are lovely.

Customer facing staff are lovely. It's very easy to get through to them and they're very helpful. Great mobile app. Interest rates are not quite as high as elsewhere, but I see that as a small price to pay for not investing in planet killing companies Reviewed on: 16th January 2024
