Maxen Power is a business electricity and gas supplier based in Ilford, Essex, serving customers from SMEs to corporates. The company was set up in 2016 as Hawking Energy Supply Limited. Ofgem has taken enforcement action against it several times since 2024, and an Ofgem investigation was still open in September 2026.

Worth knowing: Maxen Power is still trading and holds its supply licence. On 13 March 2026 Ofgem proposed a £1.25m penalty over Maxen's communications about energy theft, and that investigation was still open when we checked in September 2026.
