Green banking with best customer service

Always prompt responses to any queries, easy to switch Children's ISAs too. Ethical - on every level Reviewed on: 20th March 2026

Great values-based decision; can make improvements

I chose Triodos Bank after moving to the UK because of its commitment with sustainability - an important value for me, personally. I am happy to pay a monthly fee and know that while I may be sacrificing a bit of an interest rate, I am also contributing to build a world I’d like to be a part of. The application works well, although I would like to receive more constant notifications (e.g. every time I make a purchase) and have spending pockets in it to help my budgeting. As someone who frequently travels internationally and needs cash, I would love to be able to deposit cash directly into my Triodos accounts. Other than that, the experience has been great.
