Great - no other words!

Easy and very quick to set-up. Competitive rates of interest and the knowledge that the money invested will also be used for projects and organisations making a difference to communities and helping to sustain our beautiful planet. Customer services at Triodos are second to none - there's no waiting for hours on the phone and every representative I have ever spoken have been knowledgeable, helpful and friendly. There is only one word for this bank - 'great'. Reviewed on: 23rd March 2023

Ethical human and planet-centred banking

Completely transparent in where the money goes, so I can sleep at night knowing my savings aren't causing harm and are in fact doing a great deal of good. Great customer service - always there on the end of a phone ready to help with whatever is needed for the time it takes. Reviewed on: 23rd March 2023

ISA with excellent ethics

I’m delighted to know my tax free savings have ethical and social value, thanks to the Triodos Bank commitment to ensure money saved has a purpose. With environmental and social projects benefiting from the investment my savings also share the interest by achieving valuable outcomes I support. The transparency means investments are known and I can see reports of what the projects my money supports are achieving means it’s just about the only way I can know what a bank is doing with my money - it’s an exceptional commitment by any bank to using money for positive purposes. I’d happily recommend people use Triodos as their bank if they care about society and the planet. Reviewed on: 8th February 2023

best in Britain

See title above. If there's a better British bank I'd like to know. Reviewed on: 5th February 2023

Piece of Mind for my Family

Having been with other banks who never offered me anything truly inspiring or radically different I decided, spurred on by starting a family, to do something about it. Putting my children’s savings into an ISA account with Triodos simply offered me piece of mind that through their transparency policy that our money was never used in investments other than for good. A no nonsense bank that offer simple ethical banking Reviewed on: 4th February 2023
