Ethical banking

Money has a real impact and I am so glad I'm now able to save with confidence that it is a force for good! Reviewed on: 17th January 2023

Ethical bank providing a highly professional service

I chose Triodos originally because of its ethical values but they also provide an excellent professional service Reviewed on: 17th January 2023

Great Bank!

So nice to be involved with a business that has ethics. Innovative, efficient, kind and on the right track. Reviewed on: 17th January 2023

What a bank should be.

I've been with Triodos for quite a long time, more than 20 years. In all that time, every interaction I have had with them has been efficient, friendly, helpful and quick. They do what they say, and they're seriously interested in meeting your needs. Reviewed on: 17th January 2023

Ethical and reliable

Easy and ethical, great to have my savings put to excellent use. Reviewed on: 17th January 2023

Pleased

I'm pleased to have my savings helping what I consider to be useful projects for humanity. No issues with service so far, and feel I'm kept well informed as to what the bank is doing. Reviewed on: 17th January 2023

Conscientious Savings

Triodos has been a fantastic bank to entrust our savings with. We have 2 cash ISAs for our 2 kids, and I feel that our money is helping fund positive things for the planet while it is in Triodos’ hands. As a Geography teacher I have been very impressed with the good work that Triodos does, and I feel that our money is in the best place it could be, both for us, and for the projects we help to support. Reviewed on: 17th January 2023

Banking and not harming the world

Great cash ISA rate from many years ago. No fuss, just pay in online. Knowing your money is not being used to harm the climate or the world. Reviewed on: 17th January 2023

An ethical bank that is actually easy to use.

I have had an ethical cash ISA for many years with Triodos, after previously having had a current account with them, and now that everything is accessible online it is really easy to manage and I am happy that my money is invested in good ethical businesses Reviewed on: 17th January 2023

MIght as well have an ISA with the Good Guys

I currently only have an ISA with these guys, but plan to move more of my banking in the future. It's great to be able to deal with a bank that chooses its investments with more than profit in mind. Reviewed on: 17th January 2023
