Triodos Bank Cash ISA reviews (2645)

Totally trustable bank.

Triodos bank always promptly informs me about important information and choice about my ethical cash ISA which gives me peace of mind but what I love best is that they also keep me up to date with news of the progress and success of the wonderful projects my money helps to support. Apart from being a genuinely interesting read their regular newspaper 'The Colour of Money' means for me that I can put my whole trust in this bank and know that I am helping to do real good for so many people and for the planet with no hidden agendas. I really love Triodos Bank. Reviewed on: 26th February 2021

Excellent personal service when needed.

Prompt and helpful personal service during Lockdown was excellent and helpful at a time when customers usually get the 'staff are working from home and so we can't............. Reviewed on: 26th February 2021

Easy ethical banking

I opened my ISA with Triodos in 2014 and now have other savings products too. I love their ethos - just choosing an account with them means your money is working for good (and in many other banks it really isn't...). You'll get a warm and fuzzy feeling reading in the Triodos magazine about the organisations they help. Easy online banking and good service on the phone. Reviewed on: 26th February 2021

Triodos are great

I have invested in several Triodos products and it feels good to know my money is being used to help ethical companies grow who care about the planet, over profit. My returns with Triodos have been better than with a Standard High St bank. Reviewed on: 26th February 2021

Excellent bank that allows me to align my money with my values

I've banked with Triodos for years and have really appreciated the ease of banking with them and the services they offer. More importantly, their transparency and ethos means I'm able to 'put my money where my values are' and make sure my savings are being used to finance projects that I support on an ethical basis. Their 'colour of money' publication and regular email updates really foster a sense of community and make me feel part of a progressive movement, rather than just a bank customer! Reviewed on: 26th February 2021

Knowing my money is doing good work

I've had a great experience with Triodos over a number of years. I love to know that my savings are being used to support sustainable technologies and ethical businesses. If more of us saved this way we could change the world. Reviewed on: 26th February 2021

Ethical, accessible, good value

Triodos maintains the highest standards for ethical banking, protecting the environment and promoting social justice. Customer service is strong, return on investment is also strong. A winner on all counts. Reviewed on: 26th February 2021

A truly ethical bank

I used to be in the Cooperative Bank for many years, but that has been lost to venture capitalists. Triodos bank has a green, ethical and local focus which is in tune with the times we live in. Though only small, it is an exmpe of what banks should be like - supporting small businesses, encouraging better ways of living and leading on responses to the Climate Emergency. Reviewed on: 26th February 2021

Great service and ethical banking

I've been with Triodos for over 5 years now and couldn't recommend it enough... Reviewed on: 26th February 2021

Creating a better world

Triodos' investments in ethical businesses, and their helpful staff and easy communications are a pleasure to deal with. Reviewed on: 26th February 2021
