Philip Cullum, consumer partner at Ofgem, said: "Small businesses are an engine of growth in our economy and it is crucial they get a fair deal in the energy market. Many brokers play an important role in helping firms compare the market. However we want powers to take action against intermediaries that mis-sell."
He added: "This move sits alongside other measures we have proposed, including enforceable standards of conduct for how suppliers should treat businesses and developing a Code of Practice for brokers. We are also scrutinising the use by suppliers of rollover contracts for businesses."
