Energy companies to write with best deals

Energy companies will write to customers every year telling them the best deal for their household, Nick Clegg will announce today.

Customers could save £100 a year by switching their tariff, but 70 per cent of households pay more than they need because they are not on the best rate.

The Deputy Prime Minister hopes a new agreement with Britain’s six biggest energy firms will offer customers the most efficient deal, driving down gas and electricity bills.

In a speech, Mr Clegg will say ministers “cannot control volatile world energy prices”, but will claim the government can help people cut their bills with this “landmark deal”.
