Big Six: profits by segmentEnergy generation accounts for the largest aggregate profits of large suppliers in the UK. In 2021, the segment generated profits of more than 515 million British pounds. SSE recorded the largest energy generation profits among the Big Six at almost 670 million pounds, while British Gas and EDF Energy recorded the lowest profits.
Meanwhile, the domestic and non-domestic supply segments have waned in recent years, with losses exceeding profits by several million British pounds. British Gas was the only large supplier to record profits in the domestic sector that year. In contrast, in the non-domestic energy supplier segment EDF Energy stood as the only profitable utility.
