Caroline Flint MP, Labour’s Shadow Energy and Climate Change Secretary, commenting on analysis from Which? on energy wholesale costs and retail prices, said:

“This research adds to the growing body of evidence showing that energy companies do not pass on reductions in wholesale costs as quickly or as fully as increases. It shows why the Tories and Lib Dems made such a big mistake when they voted against giving the regulator the power to cut bills.

“The next Labour government is committed to making big changes in our energy market: freezing energy prices until 2017 so that bills can fall but not rise, reforming the energy market to make it more competitive and transparent, and giving the regulator the power to force energy companies to cut their prices when wholesale costs fall.”
