How to rebel against energy price rises

December's cold weather will add around £50 to the average energy bill. On top of that, suppliers are hitting customers with price rises. But you don't have to accept them, says Ruth Jackson. Here, she explains how to avoid the increases - and why switching supplier is a good idea.

It's freezing outside. So what we all want to do is curl up inside by a nice hot radiator and forget about the cold. But if the energy firms have their way we'll soon be shivering indoors as well as out. npower is the latest provider to put its prices up. Its customers will see their bills rise by 5.1% from 4 January. That will add around £60 to the average annual dual fuel bill. npower is the fourth of the 'Big Six' energy companies to up its prices in recent months. Scottish Power, Scottish & Southern and British Gas have all pushed up their tariffs. That leaves just Eon and EDF still offering lower prices. EDF have promised not to introduce any increases before March but Eon are now expected to put their prices up in the New Year.

With this month's arctic conditions expected to add around £50 to people's energy bills for the month the last thing we all need is a price rise on top. So what can you do to minimise the financial hit of this cold snap?

You can avoid the price rises for much of the rest of winter by using a little known regulatory rule, says Miles Brignall in The Guardian. Under the rule customers are allowed to reject price rises while they are in the process of switching supplier. You can reject the price rise up to 20 working days after receiving the letter informing them of the rise. Respond within that time and reject and you will enjoy the pre-rise prices until your switch to another supplier is complete. You then have 15 working days to find a new supplier and then the switch itself usually takes around six weeks. So time it all right and you can stay on a lower price until the worst of your winter heating usage is over.

Even if you aren't wanting to reject your provider's latest price rises you probably should still switch to a different energy firm. If you have never switched before you could save as much as £370 a year by moving to a cheaper deal. And if you have switched before you should consider moving again. Prices have been rising fast the average energy bill has doubled in the last five years so if you haven't moved provider in the last two years you could save money by switching again. To get the lowest possible bills you should switch supplier every one to two years says Mark Todd, the managing director of Energyhelplineon Thisismoney.co.uk.

The downside to a fixed deal is that if prices were to drop highly unlikely but you never know and you wanted to break your deal to switch to a cheaper deal you would have to pay an exit penalty. The penalties are usually around £20-£50. But given that when wholesale prices dropped by 40% last year the energy firms only dropped rates by 10% it's almost impossible to conceive of a situation where they would drop far enough to make a fixed deal worth breaking.
