Energy prices: should I fix?

1 September 2011

The final gas and energy price increases are due to come into effect next month, forcing customers to question the merits of fixed deals. Nathalie Bonney looks at whether you should be looking to fix your energy tariff.

E.on's prices went up on 13 September by 11.4% for electricity and 18.1% more for gas. Scottish and Southern Energy customers will pay 11% more for their electricity and 18% more for gas.

NPower have introduced its 7.2% and 15.7% increases for electricity and gas respectively.

British Gas and Scottish Power both introduced higher prices in August and EDF Energy were the last of the 'Big Six' to hike prices - 5.4% for electricity and 15.4% for gas - which will come into effect in November.

Strain on households

In spite of the drop in wholesale prices, Ann Robinson, director of consumer policy at uSwitch still foresees that the coming winter will put "significant strain" on households. She adds: "It's too soon to say whether the fall in wholesale prices is a blip or an ongoing trend so I would urge consumers to focus on reducing their winter bills now rather than hoping for good news any time soon.

"Those who are particularly worried about the impact of future price hikes on their household budget should still look at fixed price plans. Some of these offer good value and security until 2014 – you just have to be aware that if prices do go down again you may not benefit."

Outside of the Big Six…

Ovo Energy has two simple tariffs, its New Energy Plan and Green Energy Plan. Both promise  not to alter energy costs during customers' one-year fixed-rate contracts.
