Review of the Triodos Bank, Cash ISA:

Excellent all round

Through Triodos my money helps small and local, and large and global, all ethically. Decent interest rates too. Customer service both via web and phone is excellent. Reviewed on: 7th March 2021

Thank you Triodos

I use both the ISA and current account as a safe place to keep money I don't immediately need or as a reception place where I know it will be well and ethically used. Whenever I have wanted to discuss a situation or ask advice I have found it easy to get in touch and the staff reassuringly understanding and helpful. Reviewed on: 30th January 2026

Excellent ethical financial services provider, with a good customer centric informative approach. Great to find out the impact our money has. Reviewed on: 30th January 2026

All banks should behave like this!

I love the bank’s ethical approach to looking after my money Reviewed on: 30th January 2026

Transparent Banking.

Triodos have provided dependable transparent banking. Reviewed on: 30th January 2026

Management fees

The management fees are substantially lower than somewhere like Quilter and yet about 25% of my investment fund with them is held in Triodos. This feels like jobs for the boys!! Reviewed on: 30th January 2026

Ethical banking

It is so good to feel confident that money is put to good use rather than supporting a range of unethical causes (like gas and oil investment, arms development, poor trade practice) as I think is likely in most major high street banks. Reviewed on: 30th January 2026

Never a worry

I have £50,000 invested with the Triodos Bank. I am confident they are using it responsibly, ethically and in support of sustainable projects Reviewed on: 30th January 2026

Win! Win! Win!

Excellent communications and service and I know my savings are supporting very worthy causes. Reviewed on: 30th January 2026
