A Bank I trust to do no harm

I love the fact that I can choose to save money with a Bank that uses my money, to invest, support, and grow, what I would if I were the CEO of the Bank. I love the fact that I feel 100% sure of Triodos Bank's integrity. I love the fact that my money is helping others to achieve their dreams. I love the way Triodos Bank engages with it's customers. I was invited on a Customer Experience day at Yeo Valley Farm, a business supported by Triodos, a business supported by me! It was the most thrilling experience. I'd never been invited by a Bank anywhere! Reviewed on: 26th February 2021
