Energy companies will begin writing to customers every year telling them the best deal for their households, Nick Clegg will announce today.
The Deputy Prime Minister hopes a new agreement with Britain's six biggest energy firms will drive down gas and electricity bills for customers, giving them the most efficient deal.
- Customers could save £100 a year by switching their tariff.
- 70% of households pay more than they need because they are not on the best rate.
In a speech later today, Mr Clegg will say ministers "cannot control volatile world energy prices", but will claim the Government can help people cut their bills.
Mr Clegg is also expected to announce a new scheme where energy companies will print barcodes on bills, allowing customers to scan the code onto their mobile phones, linking them to the best tariffs.
