About Fuse Energy

-Founded in 2022 by former Revolut executives, the company entered a post‑crisis UK market aiming to shake up energy supply. -They built an app‑first platform that guarantees the lowest electricity tariff, undercutting Ofgem’s price cap and refunding any difference. -Alongside retail supply, they invest in and manage solar and wind farms, and are pairing renewables with electrolyzers to explore green hydrogen. -Typical projects include tariff optimization, smart meter installation, vertical integration of renewables, and hydrogen pilot systems. -Their multi‑rate and Economy 7/10 tariffs complement rooftop installations, offering both peak/off‑peak benefits and behind‑the‑meter generation. -An unusual early move: launching with real‑time consumption tracking and renewables investment from day one, blending tech, green energy and finance.
