Customers have a brief lifeline to escape soaring gas and electricity prices thanks to a new mega-cheap fixed tariff from ScottishPower.

Despite already having raised their standard rates, the new Online Fixed Saver Dec 2012 tariff is not only the cheapest fixed tariff, but also the cheapest tariff around!

However, ScottishPower has previously withdrawn cheap tariffs after only a few weeks on the market, so this tariff could be pulled at any moment.

There are only a few cheap tariffs left, and with more suppliers introducing price rises, customers need to act fast to stop their bills going up by hundreds of pounds.
