The biggest fine for an energy company goes beyond the company itself.
According to Ofgem, SSE was not just misleading customers under its own brand, but also under one of the biggest and most respected in the country: Marks and Spencer.
SSE salespeople were mis-selling energy deals on Marks and Spencer shop floors under the brand name M&S Energy. They still, as things stand, operate this contract for one of our biggest high street names.
It is not unusual for energy companies to run deals under other brands - Tesco and Sainsbury's both offer deals on gas and electricity tariffs, for example.
But being dragged into a mis-selling row is hardly helpful for companies who are trying to offer their existing customers extra services.
