Big six urged to explain pricing

%VIRTUAL-SkimlinksPromo%Ofgem has called on the Big Six energy suppliers to explain to their customers what impact falling wholesale prices will have on bills, saying the cost of both gas and electricity has been dropping "significantly" in recent months.

In a letter to the large suppliers, the energy regulator said their failure to engage with consumers on wholesale prices risked undermining public confidence and trust in the market.
