The big six energy supplier will implement an average price hike of seven per cent. This rise will come into effect on December 3 (2012).
ScottishPower - an energy supplier partaking in the Warm Home Discount Scheme - has blamed the decision on increasing costs. It has stated the rise in prices reflected the rise in costs to transport both electricity and gas to the homes of its customers. The growing amounts of investment required in energy efficiency programmes have also been blamed.
With the hike a ScottishPower customer on a dual-fuel tariff could expect to pay, on average, around Â£1,271 a year.
Chief executive of retail and generation at ScottishPower, Neil Clitheroe, stated: "We work hard to protect our customers and we regret that we have to announce a price increase.
"We will be writing to all those affected customers over the coming weeks explaining what the price increase will mean for them.
"We understand that this is a difficult time for many people and we encourage our customers to contact us," Mr Clitheroe added.
Consumer Focus' director of energy, Adam Scorer, commented: "The volley of price hikes all coming during the winter period will fuel consumer concerns about the energy market.
"Every time this happens it makes it difficult for consumers to believe that price rises are driven by real supply and demand issues. It feels as if companies raise prices in a pack because they see safety in numbers.
"When half the market raises prices in just four days, consumers will question whether this in response to the volatile commodity costs or simple pack behaviour," he finished.
