Consumers have been warned the cost of new energy deals is creeping up, after Scottish Power became the second provider in a month to replace its online tariff with a more expensive offer.
The big six provider today withdrew its Online Fixed Price Energy July 2013 tariff, which costs £1,055 a year for a typical household. Its pricier replacement, Online Fixed Price Energy August 2013, costs an average £1,086 a year £31 more.
Npower pulled its cheapest online tariff, Go Fix 11, which had an average bill size of £1,033 last month. Its new plan, Go Fix 12, costs a typical £1,150 a year.
Comparison site uSwitch.com says online tariff costs have started to creep up, hitting an average £1,101 a year. However, these deals are nevertheless generally the cheapest available.
Rising wholesale costs the price energy firms pay for gas and electricity have been blamed for the hikes.
Emma Bush, energy expert at uSwitch.com, says: "While wholesale prices have increased, we don't know whether we are looking at a short-term blip or an ongoing trend."
