About Octopus Energy and Good Energy
Who are Octopus Energy?
Octopus Energy started in 2015. It is owned by Octopus Energy Group and backed by investors such as Generation Investment Management, Origin Energy, Tokyo Gas, and CPP Investments. Through its own growth and taking on customers from failed suppliers, it is now the UK's largest domestic energy supplier. It runs its billing and customer service on its own tech platform, Kraken. Its key difference is a wide range of smart tariffs that reward customers with cheaper rates for shifting their energy use away from peak times.
Who are Good Energy?
Good Energy started in 1999, making it one of the UK's oldest renewable electricity suppliers. Esyasoft, a Dubai-based smart-grid technology firm, completed its acquisition of Good Energy in April 2025, taking the company private. It remains one of the UK's most recognised green energy suppliers. It focuses on supplying green power and helping homes generate their own, standing out by buying electricity directly from over 2,500 independent UK renewable generators.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
