Government welcomes Ofgem proposals

Energy regulator Ofgem has unveiled proposals to force suppliers to tell customers about the cheapest gas and electricity tariffs they have on offer.

Ofgem said the proposals, which the industry has described as "challenging", would make the market "simpler, clearer and fairer".

Energy Secretary Ed Davey welcomed the proposals but refused to explicitly back David Cameron's plan to force companies to put customers on their lowest tariffs.
