Simple, safe, ethical

Triados bank does everything I need it to, without cumbersom bells and whistles I don't want. Somewhere to keep and slowly grow my money safely with the peace of mind that it's being used in ethical ways. Reviewed on: 20th March 2026

The best ethical bank.

My wife and I have held cash ISAs with Triodos Bank for about 20 years because: They do not invest in fossil fuels; they invest their money ethically; there is instant access if we need to with draw money; their variable rate of interest is usually better than alternative ISAs in the market.

Ethical and sustainable

It’s really nice to have the opportunity to invest money with a bank that has environmental and ethical sustainability at its core. The app is easy to use and people I have spoken to on the phone have all been really lovely. I hope more people start using Triodos bank and thinking about where their money is going when investing Reviewed on: 20th March 2026

I've been with Triodos for years - recommended

I've had an ISA with Triodos for many years - I really appreciate their ethical stance and what they support, knowing my money is not contributing to things I do not stand for. The account is super easy to use, communication is good, rates are fair and I find the online and app banking to be really simple and intuitive. Reviewed on: 20th March 2026
