Good Energy sources its renewable electricity directly from more than 3,000 independent generators, with an 88% real-time match, and has SBTi-validated near-term targets. However, Scope 3 emissions increased in 2024 due to business expansion, fleet emissions spiked 70% in 2023, and biodiversity strategy is absent. In 2023 Ofgem found it had overcharged about 7,000 customers, and it made a £1.25 million redress payment.
