Are you on a fixed rate energy tariff? Check when it’s due to end - if you do nothing before the deadline, you’ll simply be put on your supplier’s standard rate, which is likely to be a lot more expensive.

For instance, anyone on Extra Energy’s Fresh Fixed Price Jan 2016 deal will end up paying £258.26 a year more for their gas and electricity if they don’t switch when the deal finishes at the end of this month.

In fact there are 24 fixed energy deals ending in January from seven different energy suppliers, reported uSwitch. As well as deals from Extra Energy, there a tariffs coming to an end from nPower, Scottish Power, Sainsbury’s Energy, Co-operative Energy, First Utility and M&S Energy.

Tom Lyon, energy expert at uSwitch.com, said: “Fixed energy tariffs are often hundreds of pounds cheaper than standard variable plans and protect consumers from price rises. However, when these deals end, customers can get a shock as prices usually jump when they're rolled over to their supplier's standard variable plan. If you're on a fixed energy plan which ends this month, shop around now for a better deal to avoid a shock price rise. It's worth noting that any early exit fees on your old plan no longer apply."
