My money is being used ethically. I'm so happy to know that my money is being used ethically. At my age, 78, it could be difficult to bank online but I've found it relatively easy. Reviewed on: 4th February 2026

I'm very happy with the Triodos product and service.

I'm very happy with the Triodos product and service. Although the Cash ISA doesn't offer the highest interest rate on the market, it offers the sort of investment I want to make: responsible, ethical and sustainable. I want my investment to help towards a fairer and more sustainable world, a better environment for my children and grandchildren. Reviewed on: 22nd April 2025

THE Ethical Choice for your money

I'm a long term customer - and advocate, of Triodos Bank. Triodos has great clarity for its customers, you know your money will be honestly invested in green projects.Communication & troubleshooting (online or with the app is first class.Triodos may not have the highest rates of returns or interest available, but you can be certain on how your cash will be used while you use Triodos services. They do however closely match comparable accounts from other banks. Reviewed on: 22nd April 2025

Ethical banking that earns me good interest.

I'm very happy with Triodos' value for money in a seemingly otherwise dire landscape. The added bonus is that I know my money is being invested in ethical businesses and ventures - something I can't say for other banks. Reviewed on: 22nd April 2025
