Green the world

Saving with Triodos Bank means that I help support businesses and organisations who are improving the world in a green and organic way. Reviewed on: 19th January 2022

Benefits for a better, greener society

I opened an ISA with Triodos because I wanted my money invested in ethical and environmental organisations; where there is real benefit to society and it is not just a box ticking exercise. Triodos are very transparent in where they are investing, and how those businesses are doing; I am very happy that I am involved in growing such businesses. The communications on investments are authentic, rather than being 'show-offy'. I was pleasantly surprised to find out that they offered one of the higher interest rates compared to equivalent products from big name banks. Reviewed on: 18th January 2022
