A new postcode survey created by energyhelpline contains a big shock: people in the North are actually paying higher energy prices than in the South, where living costs are traditionally higher. So where customers might think they have a good deal on their gas and electricity bills, they could be paying over the odds. Although it's not easy to change your postcode, it is easy to compare your bills and switch to a cheaper tariff with energyhelpline.

Energyhelpline pays affiliates commission for each switch, with added bonuses for higher numbers of switches.
