AROUND 100,000 Scots customers of energy firm EDF were today hit by the news that the firm plans steep gas and electricity price rises.

The French-owned company, which blames "soaring" costs said it was upping gas prices by 12.9% and electricity by 7.9% from Friday.

Earlier this month rival Npower announced price hikes of 17.2% for gas and 12.7% for electricity, hitting more than four million households.

EDF's announcement will see the average annual cost for one of its dual fuel customers rise around £100 to £1007.

It also led to fears that Britain's biggest energy supplier, British Gas, could reveal price rises as soon as tomorrow.

The announcement happened on the day chancellor Alistair Darling was due to meet with energy regulator Ofgem to discuss the state of the energy market.

Energy consumer group energywatch said it was disappointed and chief executive Allan Asher also renewed his call to refer the big six' suppliers - British Gas, E.On, Scottish & Southern Energy, Npower, EDF and Scottish Power - to the Competition Commission.
