The average dual fuel bill from the supplier will increase by 8.6 per cent (£113) from 6 December.
Gas prices will rise by an average 8.5 per cent and electricity prices will increase by an average of 9 per cent.
Scottish Power blamed rises in the wholesale energy costs, increased transmission and distribution charges, and additional costs to meet the government’s environmental and social schemes.
Neil Clitheroe, chief executive at Scottish Power Reatil 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.
“We understand that these are difficult times for many families, and we have done what we can to hold our prices for as long as possible.”
Scottish Power will not be increasing the prices for customers on its Fresh Start social tariff until 1 March 2014 to “help these customers through the winter period”. These customers will be moved onto a standard tariff from March 2014.
The company will now write to the 2.2 million customers that will be affected by the price rise.
The move comes after SSE, British Gas, Npower and Co-op Energy have already announced their price rises for the winter months.
