Energy giant ScottishPower today announced it will increase gas prices by an average of 8.5 per cent and electricity bills by 9 per cent from December 6.
Spanish parent firm Iberdrola warned in third-quarter results yesterday that it had “no option” but to increase tariffs in the UK after claiming ScottishPower had been hit by the Government’s energy efficiency and environmental measures.
ScottishPower is the fourth of the “big six” suppliers to reveal energy price increases so far this month, following British Gas, SSE and npower.
Its bills blow also comes just days after ScottishPower agreed to fork out £8.5 million to customers following an investigation by regulator Ofgem, which uncovered mis-selling by its doorstep and telesales agents between 2009 and 2012.
ScottishPower said on average prices will rise by 8.6% across the board, but admitted customers in the South and South East will face average rises of 10.2%, while those in the Midlands will see tariffs increase by 9.3%.
Neil Clitheroe, ScottishPower’s chief executive of energy retail and generation, said: “The cost of purchasing and delivering energy to homes across Britain has risen significantly this year.
“With an increase in costs for delivering compulsory schemes to reduce carbon emissions and improving energy efficiency in homes, we unfortunately have no other option than to pass these on by increasing our prices for customers.”
Iberdrola yesterday said its UK retail and generation business suffered a £23 million operating loss in the first nine months of the year.
