Best Buys 2021: Best for Sustainable Investors - ISA

By Mike Narouei, Content Producer at Boring Money

24 Feb, 2021

The best investment platforms and robo advisers for sustainable ISA investors. Based on customer reviews and expert analysis of 30 test accounts.

We wanted to identify providers who have tried to help investors identify sustainable funds or portfolios to invest in. We looked at the supporting product range and availability of curated fund lists as well as supporting research and information – it's depth, accessibility and how often it is refreshed. We considered the associated costs of sustainable investment options in conjunction with the associated platform or administration fee.
