I’m just SO glad Triodos bank exists! Best decision I ever made was to bank and invest with them. With their help I am now able to more effectively vote for the change I want to see in finance -and in the world. Just love what they do, also great customer service -would absolutely and highly recommend! Reviewed on: 15th January 2022

Ethical is best

As good as any other bank bur ethical which is what counts most of all Reviewed on: 15th January 2022

Reliable and ethical

I've kept my savings with Triodos for several years. I was recommended by a friend who told me about the wonderful ethical projects my money would go to. I've found them particularly easy to reach and helpful on the phone. Reviewed on: 15th January 2022

A genuinely ethical bank

We get regular updates about the ethical businesses that our ISA supports. Now planning to switch my current account as well, since my old bank has made no effort to get out of fossil fuels. Reviewed on: 15th January 2022

Reliably ethical

Many companies now greenwash & flout their ethical credentials often when these are opaque or highly questionable. Triodos has always been reliably ethical as part of its raison d’etre. I wouldn’t trust any other bank on its ethical credibility as I do Triodos Reviewed on: 15th January 2022

Best bank ever!!!

My parents introduced me to Triodos and I couldn’t be happier to actually trust in my bank. So grateful for you. Reviewed on: 15th January 2022

Quick access - local connections

I was intrigued when I discovered that 2 local community enterprises 5 mins from my home had been funded by Triodos - a yoga centre and community veg shop. I knew them and used them and so knew exactly where the money was and how useful the investments were! Reviewed on: 15th January 2022

Ethical throughout

Investing through Triodos gives me the confidence that my money is being used to benefit charities, environmental causes and independent entrepreneurs; and is not being used in ways that are detrimental to our planet and its inhabitants. Reviewed on: 15th January 2022
