About British Gas and Good Energy
Who are British Gas?
British Gas is owned by Centrica and is one of the UK's oldest and largest domestic energy suppliers. It supplies gas and electricity alongside home services like boiler cover and Hive smart technology. A key difference is how it links its energy tariffs with Hive devices to give customers cheaper rates at certain times. It also runs a charity to help people in energy debt.
Who are Good Energy?
Founded in 1999, Good Energy is a smaller, independent supplier focused on renewable power. It supplies gas and electricity and installs solar panels, home batteries, heat pumps and electric vehicle chargers. What sets it apart is that it buys electricity directly from a network of independent UK generators rather than just buying certificates.

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.
