Triodos Bank Cash ISA reviews (2841)

My review

5
I only save with ethical banks and building societies. I won't lodge my savings with banks who work for shareholders instead of customers, who don't lend money to those who can't repay, who don't spend Government bail out money giving big bonuses to directors who didn't do their jobs with necessary due diligence & are delighted to pocket their big bonuses. We have those awful greedy people to thank for low interest rates on UK ISAs while horrid lenders charge the poor huge high rates. I'm relieved Triodos doesn't do that.

I want my savings to earn me some interest but I want to know that my money is working for forward thinking, imaginative and ethical projects in a safe and sustainable way in the meanwhile. Reviewed on: 26th February 2021

Totally trustable bank.

Triodos bank always promptly informs me about important information and choice about my ethical cash ISA which gives me peace of mind but what I love best is that they also keep me up to date with news of the progress and success of the wonderful projects my money helps to support. Apart from being a genuinely interesting read their regular newspaper 'The Colour of Money' means for me that I can put my whole trust in this bank and know that I am helping to do real good for so many people and for the planet with no hidden agendas. I really love Triodos Bank. Reviewed on: 26th February 2021

Excellent personal service when needed.

Prompt and helpful personal service during Lockdown was excellent and helpful at a time when customers usually get the 'staff are working from home and so we can't............. Reviewed on: 26th February 2021

Easy ethical banking

5
I opened my ISA with Triodos in 2014 and now have other savings products too. I love their ethos - just choosing an account with them means your money is working for good (and in many other banks it really isn't...). You'll get a warm and fuzzy feeling reading in the Triodos magazine about the organisations they help. Easy online banking and good service on the phone. Reviewed on: 26th February 2021

Triodos are great

I have invested in several Triodos products and it feels good to know my money is being used to help ethical companies grow who care about the planet, over profit. My returns with Triodos have been better than with a Standard High St bank. Reviewed on: 26th February 2021
