The online Cashh ISA is easy to use.

The online Cashh ISA is easy to use. I can add money or take money out through my online account. I simply transfer money to a current account to take money out and viceversa to put money in. I get interest to my account yearly. Reviewed on: 25th March 2026

Reassurance that my money is being used ethically

I normally prefer a bank that has a branch that I can go into, but for an on line bank it is very easy to use, when I have a problem it is easy to speak to an actual person and I very much like the fact that I know my savings are going to an ethical bank Reviewed on: 25th March 2026

Smooth user experience; clarity and ethics

the user experience has been very smooth, from set up to account management. I like the clarity of comms regarding investments. I feel good about banking ethically. In terms of climate change I recognise it's one of the biggest impacts I can have as a consumer. Reviewed on: 25th March 2026
