An expert website has advised consumers to switch gas and electricity companies to a fixed tariff provided by EDF.
According to LoveMoney.com, the EDF annual fix v2 offers a fixed rate until the end of March 2010 and customers subscribing to it will face bills no more than four per cent higher than competing tariffs.
The four per cent difference will be offset by the warm summer months when domestic usage drops to its lowest for the year and then customers will not be affected by any price rises when the autumn and winter beckon.
Although the fixed rate will lead to slightly higher summer bills, if prices rise by 15 per cent in the autumn and winter of this year then higher domestic energy use could result in fixed tariff customers paying 11 per cent less than those who stick with variable rates.
If prices increase by more than 15 per cent, the saving increases even more.
People considering a switch to a different energy supplier could also save money by installing cavity wall and loft insulation.
