A further three energy retailers have ceased trading, leaving another 233,000 customers for the supplier of last resort (SoLR) process. The failures of Igloo, Symbio and Enstroga Energy take the total number of market exits so far this year to 12, exceeding the previous record of nine set in 2019. Igloo's founders said the market had become unsustainable and accused Ofgem of ignoring calls to reform a price cap methodology which "is designed to favour the largest suppliers".
