The cheapest energy tariff we've seen this year has launched today – and it could take an average household's annual bill down to under £1,000.

Prepaid energy customers will have more choice over getting a fixed gas and electricity tariff, as EDF has today announced it'll become the second of the big six energy suppliers to offer one.

Post Office customers with home phone and broadband bundles will see the price they pay fall from 14 April, but customers will lose their free evening calls and be hit by a £1/month line rental increase.

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.

Energy companies are charging their most loyal customers up to £90 more than those who have switched to them, according to new figures.

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

Update: 1 April 2014: Ovivo's website now says it will go offline completely on Thu 10 Apr – meaning it's unlikely you'll be able to request a PAC code (to keep your phone number) after then. We're still trying to get an explanation from Ovivo as to what's happened, so keep coming back here for updates.

Energy minnow First Utility has undercut its rivals by launching the market's cheapest tariff – but is it worth switching to?

If you've signed up to a fixed price energy tariff in the past few years, your bill could be about to soar as 15 deals are ending soon. But you can beat the hikes – if you act now.
