Ethical investment at its best

I love the transparency of knowing which ethical projects support my Isa investment. Lovely customer support as well Reviewed on: 21st April 2026

I have found banking with Triodos to be a rewarding and smooth experience but primarily I value them for their ethical values. Reviewed on: 21st April 2026

Honestly ethical

Being able to have all my investment needs met with such devoted ethicity and efficiency is very reassuring. We need integrity and trust when we need to save money. Knowing that it s not being used to fund any potentially harmful projects gives me hope for my grandchildren's futures. Being able to talk to a human being if necessary is also important to me and something I value if I m not sure of a process I have to undertake.Thanks Triodos! Reviewed on: 21st April 2026

Good telephone support

I needed help over the phone to transfer money to my account. The person I spoke with was helpful, knowledgeable, professional. Reviewed on: 21st April 2026

Triodos Bank is the most ethical!

Triodos Bank is excellent. It is very easy to get through to them on the phone and I like their approach which is less formal and much friendlier compared to other banks. It is a shame there are no high street branches, although I understand that would incur more costs and carbon emissions, less money to invest in positive, ethical projects. My main reason for choosing them is because they are the most ethical bank, both for what they do and do not invest in. In addition, you do earn a reasonable interest rate on your savings, Reviewed on: 21st April 2026

While not the highest interest rate sustaining life on the planet is not just about money but more about People and Planet and Triodos are firmly rooted in supporting this approach Reviewed on: 21st April 2026

Easy to use. Helpful staff.

The account is easy to access and funds can easily be transferred in and out. Contact using telephone or online chat is quick and helpful. Reviewed on: 21st April 2026

Excellent Account

Very easy to open account. Good information about the ethics of saving money with Tridos. Brilliant updates Reviewed on: 21st April 2026

Easy to setup, good response times and good transparency. Interest rates could be a little better if possible but the positive impact is more important. Reviewed on: 21st April 2026
