Energy watchdog Ofgem is looking into recent gas and electricity price rises, to see if more action is needed to protect consumers. It said that the net profit margin of £65 per typical customer in September was now £90, a 38% increase. "The energy retail market can only be fully effective if consumers have confidence that the market is transparent and easy to take part in," said Ofgem chief executive Alistair Buchanan. "So we will go beyond our usual quarterly reports on prices and do a comprehensive review of the retail market."
