Customers will see energy bills rise by £86 a year as supplier becomes third of the big six to raise prices
More than a million Scottish Power customers will see their energy bills rise by £86 a year after it became the third of the big six energy suppliers to announce a price hike.
But British Gas, the biggest energy supplier, announced on Friday that it would freeze prices until August, contrary to recent reports that it was planning a rise of up to 9%.
