Triodos is a really impressive ethical bank

Triodos is a really impressive ethical bank whose values I admire. But also their products are easy to access and use (their app is great) and their customer service is excellent. You can always get through to someone directly and they are very helpful. I would never bank with anyone else now. Reviewed on: 4th March 2025

Great ethos and good returns

My cash ISA earns good interest and it’s good to know that my funds are being wisely invested in environmentally and climate friendly projects, NOT fossil fuel companies Reviewed on: 4th March 2025

Good principles and excellent service.

I have been with Triodos for about 30 years and they have consistently shown the value of a bank with great ethical principles - which make me even more keen to invest my money with them - and they combine this with excellent service. Triodos is also very keen to enhance security and so I trust this bank fully. Reviewed on: 4th March 2025

The customer service is so easy to access and the staff are always kind and clear when explaining any questions I have. I transferred my ISA to Triodos because I want to start thinking about ethical banking. Reviewed on: 4th March 2025
