Top marks to Triodos

I've only dealt with Triodos online. It's always been easy to open accounts & move money. The website is clear & simple to use. I bank with Triodos because of its ethical stance, which from what I've read is amongst the best in the banking sector. It's products also have very competitive rates. Reviewed on: 20th March 2026
