SmartestEnergy is an energy company serving business customers, with activity across buying, selling and trading power and supporting the UK’s transition to net zero. SmartestEnergy also works with independent generators through routes such as power purchase agreements and related renewable market products. SmartestEnergy sits within the SmartestEnergy Group, with corporate backing from Marubeni. The company operates across the UK, US and Australia and hires across trading, risk, operations, tech and corporate functions.

SmartestEnergy operates across the UK, US and Australia, with UK locations including London (Canary Wharf) plus operational sites such as Ipswich and Worthing. SmartestEnergy advertises many roles as hybrid, with some fully remote roles depending on team and location.

SmartestEnergy has clear early-career signals through a defined graduate trading scheme launching for September 2026 and visible apprenticeship activity across multiple business areas. SmartestEnergy also makes pay and benefits unusually legible for a mid-sized energy firm, including publishing salary for the graduate scheme and stating core benefits in public FAQs. The score is capped by limited public evidence on early-career outcomes like conversion rates, time-to-promotion, and retention by cohort.
