Triodos Bank Cash ISA reviews (2680)

investing in a better world

Triodos invest in many and varied small scale businesses with ethical values. It offers crowdfunding opportunities to invest in a better world. Reviewed on: 25th January 2022

Transparency and service

Very transparent with investments and quick to help whenever asked especially when phoning Reviewed on: 25th January 2022

The Bank for the Future

I have quite a bit of money in Triodos bank, and will leave it there for as long as possible. I would much rather have my money in a place that is helping climate change, and new cleaner projects, than in a bank that keeps its investments secret, because they are involved with fossil fuels, and other destructive projects. Reviewed on: 25th January 2022

Best place for ethically investing and for helpful service.

Gives plenty of information on where investment goes and why. Also have current account with Triodos and find it easy to use online with phone back up when necessary Reviewed on: 25th January 2022

Very good

I like the idea that my investments are part of a bigger sustainable future Reviewed on: 25th January 2022

Saving for my future - and the planet

There's no point saving or investing for my future if my bank is busily undermining it through its holdings and portfolio. I love the fact that with Triodos I know my money is going to support the kind of world I want to build. They are also excellent and transparent in their communications. Reviewed on: 25th January 2022

Trusted ethical bank

Good interest rate on my isa where possible. Fairly easy to use internet banking. Helpful and understanding helpline. The only consistently ethical bank I can use. Wouldn't be without it! Reviewed on: 25th January 2022

Aligned

It’s refreshing to find a bank that have values aligned with my values. Reviewed on: 25th January 2022

Triodos the true Green Banking option

The only bank to do what it says, invest in green sustainable projects Reviewed on: 25th January 2022

Triodos is the bank of now

Triodos has helpful people at the end of the phone line, they answer straight away, they solve problems and stay cheerful. And I know my money is going to support good, ethical causes. Reviewed on: 25th January 2022
