Energy Secretary Ed Davey has welcomed Ofgem's proposals to force energy companies to inform customers of their cheapest tariffs.
The Energy Secretary said: "These are the sort of measures I have been urging for some time."
"I want an energy market where the suppliers have to work hard to win your business, and then work hard to keep it. Making bills simpler and easier."
The regulator proposed that suppliers should offer four core tariffs to cut the "baffling" array of tariffs currently on the market.
The plans come after Prime Minister David Cameron backtracked on a commitment to require energy firms to give households the cheapest deals, rather than simply inform consumers what is available, as unveiled by the regulator on Friday.
