There's never been a better time to change energy tariffs

Gareth Kloet, product director at Confused.com, the UK price comparison website, responds to npower's and Scottish Power's recent energy price rises, which will hit an estimated 11.8 million customers. These latest announcements follow price rises by Scottish and Southern, British Gas, EON, and EDF: "We are living in unusual times! Energy prices have risen by more than 40 per cent this year alone, as a result of unprecedented rises in the cost of wholesale energy and, consequently, double digit rises have become the norm.

"Despite the fact that all of the ‘Big Six' providers have now raised their prices, supplier prices are still in a state of continuous flux. In fact, it has never been more important to make informed decisions when it comes to changing energy tariffs, based on personal circumstances.

"While capped tariffs will offer insurance against future rises, it is important to note that customers will pay for this fixed-price assurance. This makes the cost 20% higher, on average, than that of uncapped deals. While uncapped deals, in the current climate, will result in the most significant savings, there is no guarantee that these prices will remain as competitive and attractive in the near future. It is important to also consider online deals and paying by direct debit, as companies often offer discounts to customers who elect to use these methods.

"There is scope for saving money if you act fast and change supplier or tariff as soon as possible; however, it may be best to stick to one of the ‘Big Six' suppliers, as volatile price fluctuations have forced smaller suppliers out of the market in the past."
