So Energy Rebrand & Brand Identity

So Energy is a UK renewable energy supplier that aims to be the ultimate challenger to the Big Six. Studio Blackburn's 2025 rebrand updates the identity the studio built in 2021, making a high-visibility yellow-green called Electric Yellow its signature on comparison sites and social, and redrawing its icons, all under the idea of outcome over utility. Energy is invisible and commoditized, and the brand needed more character and clarity so that switching feels worth the effort.
