Scottish Power energy prices
Following the fall in wholesale energy prices, on 20 January 2015 Scottish Power announced a 4.8% price cut with effect from 20 February. The cut is equivalent to a £33 reduction to the average annual gas bill.
Scottish Power raised gas prices by 8.5% and electricity prices by 9% in December 2013.
It was the fourth energy company to announce price rises in October 2012, introducing average increases of 7% for both gas and electricity prices. Back in January 2012, it was the last of the ‘big six’ suppliers to announce it would lower gas prices by 5%.

Scottish Power in the news
In September 2015, Scottish Power came last in a Which? survey of 100 best and worst brands for customer service, with a customer service score of 59%.
On 4 March 2015, Scottish Power was hit with a 12-days sales ban after failing to resolve customer complaints, and missing Ofgem's targets to sort them by the end of November. Scottish Power was also warned to improve the speed of answering customer calls and reduce the amount of late bills.
On 22 October 2013 Scottish Power was fined £8.5m by the regulator Ofgem for providing misleading information through its doorstep and telesales agents between October 2009 and January 2012. If you think you might have been affected, you could claim compensation by calling Scottish Power on 0800 074 0362.
Only two days later, it announced an average price rise of 8.6%, effective from 6 December.
Scottish Power had the joint lowest number of complaints received per 1,000 customers in the final quarter of 2012 of the big six, according to data published in February 2013. It had an average of 14, along with competitor SSE. However, 68% of its complaints were resolved the same day or the next working day, compared with 75% of SSE’s. All of the big six suppliers published the comparable data following changes made by Ofgem, after Which? campaigning.
In 2012, Which? praised Scottish Power for helping customers compare prices more easily by giving them better access to their up-to-date energy usage history. Customers with an online account can use Scottish Power's website to request the data, which they receive in a spreadsheet.
We were pleased to hear that Scottish Power decided not to pursue the development of its venue sales - where energy advisers use supermarkets or shops to sign up new customers - following discussions with Which?. We have concerns about how some of these sales are taking place and have asked all energy suppliers to review their practices. Scottish Power responded very positively.
In May 2014, Scottish Power had to pay £750,000 following an investigation by the regulator Ofgem which found that the supplier did not have a robust process in place to assess the cost of different payment types. This means that some customers might have been overcharged for paying with a certain payment method.
Scottish Power has had a hard year. It came last in our call waiting investigation, with an average waiting time of 30 minutes for customer service, but only a minute for its sales line. It was told by Ofgem to improve the way it treats customers and reduce the number of outstanding bills it hadn’t sent, or face a sales ban. And the number of complaints it receives is steadily going up.
However, it offers one of the cheapest fixed deals on the market.
Pros: Competitive fixed deal, no exit fees
Cons: Poor customer service
