Corona Energy is a business gas and electricity supplier owned by Macquarie Group, based in Watford with a second office in Coventry. It says it supplies around 17,000 customers with over 84,000 meters, and has 14% of the UK industrial and commercial gas market. It serves businesses from micro to corporate, as well as the public sector.

Worth knowing: Corona Energy is still part of Macquarie. In 2025 Macquarie reorganised the companies that own the supplier, and the former holding company, Corona Energy Limited, is now in liquidation. The supplier itself, Corona Energy Retail 4 Limited, has been owned directly by Macquarie Corona Energy Holdings Limited since 7 July 2025.
