Energy Secretary Chris Huhne is expected to announce his intention to¬†“get tough” on energy companies¬†when he speaks at the Liberal Democrat conference today.

The “big six” energy companies have all increased their price tariff recently and Mr Huhne will say he wants everyone to have affordable energy.

Mr Huhne is expected to say, “It’s not fair that big energy companies can push their prices up for the vast majority of their consumers, who do not switch, while introducing cut-throat offers for new customers that stop small firms entering the market.
