How do the new energy bill proposals work?
The six big energy companies will write to people once a year (twice a year for the poorest) to inform them on what the best tariff is for their household.
The firms will also print barcodes on bills, allowing customers to scan the code onto their smart phone linking them to the best tariffs.

The Deputy Prime Minister claims his new proposals could save you £100 a year.
He says that 70% of households are paying more than they need to as they are not on the best rate.
