Why choose to invest in a Stocks & Shares ISA ?

  • You don't pay tax on any growth or returns in your ISA.
  • You can start from £25 a month and invest up to £20,000 every tax year (under current rules) - tax free!
  • You understand that investing isn't guaranteed to make you money and your money can go up and down in value.

  • It's Ethical Consumer's 2022 Best Buy Stocks and Shares ISA.
  • Awarded Boring Money's Best for Sustainable Investing 2021 and 2022.

Why choose to have your account with The Big Exchange?

Investing on The Big Exchange gives you confidence that whatever fund you choose, it has been analysed and rated for its positive impact on the world. We are proud to give you more transparent investments, to show you we are running an ethical business model, and that we are avoiding greenwashing.


We provide an impact summary and a rating for every investment. You can read all this information before you make your choice.

We are also one of the only investment platforms in the UK that gives you full sight of all the companies that are held in your fund.


We are co-founded by The Big Issue, whose mission is to dismantle poverty by creating opportunity through self-help, social trading and business solutions.

As a mission driven business we also have social and environmental goals at our core.

No Greenwashing

We don't let funds onto The Big Exchange that cannot meet our criteria and go deeper than marketing.

We aim to call out any potential issues we find in a fund before you choose it. Whether its alcohol, intensive farming, nuclear power or more. We want you to know.
