The UK government has agreed a deal with the country's major energy suppliers that could see consumers benefit from cheaper gas and electricity bills in the future.
Under the commitment from EDF, E.On, British Gas, Southern, Scottish Power and Npower, customers will be sent letters at least once a year informing them of the best tariff for their needs and how they can switch on to it.
More than 120 different tariffs are currently available, but seven out of ten householders are not on the best possible deal. Throughout 2010, three-quarters of people stuck with the same tariff.
Announcing the move, Deputy Prime Minister Nick Clegg said: "I know that many families are struggling with rising energy bills.
"We can't control volatile world energy prices, but we can still help people get their bills down."
The measures have been welcomed by Audrey Gallacher, director of energy at Consumer Focus, who described the plan as a "long-overdue step".
