What is investing on The Big Exchange?

We don't just let any investment on The Big Exchange. Whether it aims to have an: ethical, sustainable, responsible, or impact strategy, every one that you see must prove its positive contribution to people and/or the planet. If it doesn't, you won't see it.

Rated investments

We rate all investments against our unique impact methodology.

Every investment needs to pass this test so that you can see the positive impact it could have on people and the planet.

Expert investors

We work with some of the biggest and most trusted names in sustainable investing.

But having a big name doesn't change the rules. All funds are tested equally to get their rating.


Our charges are some of the lowest you'll find.

For a service that rates the investments before they're put in front of you, we're proud to do more for less.

Investing is not guaranteed to make you money. Your capital is at risk. Please remember that tax treatment depends on the individual circumstances of each customer and may be subject to change in the future.
