The First Utility iSave Fixed v10 tariff enables homeowners to sign up for fixed prices up until January 2016.
It's been earmarked as the cheapest tariff covering such a timescale, and homeowners could expect to pay £1,274 on average per year.
Speculation has been rife that the big six energy suppliers are planning to increase their prices - rises of between 5 per cent and 10 per cent have been predicted by industry experts, and could take effect in the next couple of months.
And for that reason the deal is expected to be a popular option amongst homeowners looking to fix their energy bills in the lead up to winter.
The big six energy suppliers are also taking part in the government's Green Deal initiative. It enables customers the opportunity to fund the costs of installing measures to improve the energy efficiency of their homes - such as an energy efficient boiler or loft and wall insulation.
However, rather than having to pay the costs back in one lump sum, the Green Deal enables them to pay for these measures as they would a loan, in smaller sums, paid as part of their monthly or quarterly energy bills.
