I like what the bank does with my money

I only use it for my ISAs and i am confident that my money is being used in a positive way for the planet Reviewed on: 4th February 2020

Positively ethical, positively helpful

I put money into Triodos as it doesn't just avoid things I disapprove of, but actively supports things I would like to support, benefitting the environment and society. And as a company, its customer care is exemplary. That surely makes it the best of banks. Reviewed on: 4th February 2020

A better world is possible!!!!!!

Triodos is a bank that should be copied by every institution! Anything else should not be permitted to exist because of the great harm they inflict!!!! The money system as we know it is not fit for purpose and never has been as the results show. We cannot eat money. Reviewed on: 4th February 2020

A good choice of ISA

I decided to move an ISA to Triodos because I value the company's ethical stance. I had expected the process to be a bit tricky, having had not entirely happy experiences with other banks in the past, but everything worked like a dream. There were a couple of things I wasn't sure about but the Triodos staff member who answered my phone call understood exactly what I wanted to know and gave me very helpful answers, so the whole process was extremely quick and straightforward. The website works well and I can see how may savings are doing. the return is not bad but the more important thing for me is that I'm happy that my money is being used ethically.

Ethical banking

It is great to be able to bank with a company that works by our principles and uses our money for causes we believe in. Also when you phone they are human and friendly like no other bank I know. Reviewed on: 4th February 2020

Best bank in UK

Researched ethical savings in UK and decided that Triodos offers the best options. My Pioneer Fund ISAs have performed extremely well, and am pleased to invest in a bank which cares about sustainability and ethics. Reviewed on: 4th February 2020

I use Triodos for everything except instant transactions, and have done for several years.

good service, and nice to know where my money is going. Reviewed on: 4th February 2020

Refreshingly positive banking

The online interface is easy to use, but the best part is that there's always a new, refreshing story on the main website, about companies or initiatives that are supported by or that bank with Triodos, and that are doing good in the world. I feel confident that my money does not exploit our environment or other people, and indeed, it contributes, through Triodos, to a more positive world. Reviewed on: 4th February 2020
