Review of the Triodos Bank, Cash ISA:

A bank that doesn't invest in fossil fuels

I love that this bank doesn't invest in fossil fuels, what a powerful way of looking after the environment! Great app and customer service too Reviewed on: 15th April 2025

A great bank and a great way to save ethically

We chose Triodos for its ethical stance when we wanted to open a savings account for our first grandchild. We were impressed with the bank and have since opened our own account with them. Staff are efficient and friendly. Reviewed on: 28th February 2021

The future of investment, here and now

I can rest easy in the knowledge that my investment is doing more than no harm - it's actively ethical and sustainable. A no-brainer if you believe money is not the most important currency we humans have! Reviewed on: 28th February 2021

Great product, wonderful bank, amazing people

I can still remember clearly, even though it was over fifteen years ago, my first Triodos AGM. It was so inspiring. The combination of intellectual rigour, long term vision and compassion was so unlike any other banking/financial experience I had had. There are many banks with slick adverts that purport to be thinking sustainably but Triodos actually does, and has been doing it for decades. The customer service is awesome - speak to people who know and care. The products themselves are clearly laid out, do exactly what they say and offer reasonable returns - crucially amazing returns in terms of what the products do in the world. Best bank ever. Reviewed on: 28th February 2021

Triodos - excellence

First, reassurance, choice and peace of mind around what my funds are being used for. Second, very good service. Highly recommended. Reviewed on: 28th February 2021

Problem free ethical banking

Excellent service and easy to use with good information and back up Reviewed on: 28th February 2021

So glad I found them

I have looking for somewhere to invest ethically but never knew of such possibilities until I found Triodos. The paperwork is easy to understand and their customer service is first class (a lot of other banks could learn a thing or two). I only wish they did mortgages, as I would move ALL my savings to them for offsetting). Reviewed on: 28th February 2021

Excellent ethical products and good cusomer experience

Have had 2 sustainable Isas with Triodos for some years.. .They've performed well over this time. Good customer service. and 3-monthly valuations. Am relieved to know that my money is not being used to fund the arms trade, fossil fuels or deforestation. One of only a few banks that are reliably committed to ethical investment. .
