Ofgem

Energy customers will be able to switch suppliers in three weeks under a shake-up planned by regulator Ofgem.

The big six energy companies could face a full-scale investigation into whether they are preventing competition in the market and making excess profits, reglator Ofgem has announced.

Big six energy supplier Scottish and Southern Energy (SSE) is to freeze household gas and electricity prices until at least January 2016.

Gas and electricity provider Economy Energy has been told it must clean up its act or risk having its licence taken away.

If you've switched energy provider in the last six years, you could be owed a slice of £200 million after energy regulator Ofgem found the big six suppliers guilty of failing to return money to millions of former customers.

The big six energy suppliers will be fined if they fail to meet new rules aimed at helping smaller firms break into the market, the energy regulator says.

Energy Secretary Ed Davey wants the energy regulator to look into the profits the big six energy companies make on gas bills.

If you're thinking of switching energy provider, be aware that energy prices haven't dropped this year – even though firms are now listing lower annual costs on websites.
