E.ON to cut electricity bills by 6%
The move will come into force from Monday February 27, shaving £31 off the average annual bill, but the group left gas prices unchanged.
It became the fifth of the big six suppliers to announce a cut in recent days after falls in wholesale prices, although none has yet cut both gas and electricity.
British Gas last week cut bills for more than five million customers by making an instant average cut of 5% in its standard electricity tariff.
Southern Electric and Swalec owner SSE said it would cut the price of household gas by 4.5% from March 26, while French-owned rival EDF cut gas prices by 5% from February 7. Other operators are expected to follow suit. Only Scottish Power has yet to announce a cut.
E.ON UK chief executive Tony Cocker said: "We understand that household bills are the most pressing concern for families across the country.
"Whilst we're pleased to pass on this recent slight fall in wholesale prices, most experts agree that global energy prices will continue their long-term rise."
