My flexible cash ISA is a good place to hold my savings

I have a flexible cash ISA with Triodos, which means that I can put back into the ISA, funds that I have taken out, in the same tax year, without affecting my ISA allowance. Withdrawals are paid into the linked bank account within 2 hours regardless of which day of the week of the week it is. The ISA gives a good rate of tax free interest.

Ethical investment

Excellent place to invest with a conscience Reviewed on: 21st April 2026

Ethical values

I like banking with Triodos because it is ethical Reviewed on: 21st April 2026

Ethical Banking Made Easy

I needed to set up a cash ISA at very short notice as the deadline was approaching. It was very easy to set up the account and pay into it within a day. I later decided to open a savings account, which was also very easy to open and pay into. The online Banking App recently had a redesign which makes it clearer and more aesthetically pleasing to use. The Bank regularly communicates via email about the impact of its ethical investments. Reviewed on: 21st April 2026

Ethical and straightforward.

Good to know your money is helping other people and the planet. Clear, easy to use mobile app too. Reviewed on: 21st April 2026

More Niche

More niche than the usual retail bank. I’d definitely recommend but only to those who would be aligned in their opinions with that of the bank. Reviewed on: 21st April 2026

Always Quick & Helpful

I've only had to contact Triodos a few times but they have always been very quick & helpful. Most of the time I have no issues at all, they just get on and do the job. If only all banks were more like them the world would be a better place. Reviewed on: 21st April 2026
