Top five cheapest energy deals revealed

Beat price rises by switching to a cheaper deal


With energy bills set to rise for many this winter, Which? reveals the five cheapest energy deals available right now. 

Several fixed-rate tariffs from four of the ‘Big Six’ energy suppliers – EDF Energy, Eon, Npower and Scottish Power – are due to end soon, and customers on those deals will be moved onto more expensive standard tariffs, so if you’re one of those customers, now’s the perfect time to look for an alternative.

The cheapest tariff currently available – based on the average usage for UK households – is the M&S Energy Fix & Save Tariff at £1,139 per year, which fixes your prices until September 2014.

The most accurate way to compare gas and electricity prices and is to visit Which? Switch – tell us your current tariff and how much energy you use and we’ll compare energy prices and find the cheapest deal for your specific needs.

Cheapest energy deals

After the M&S Energy deal, the next cheapest tariff for an average household is the First Utility iSave v16 (dual fuel), which is £1155.47 annually.

This is the cheapest non-fixed deal with no end date and therefore no charges if you decide to swap deals. It’s only available to online customers.

The rest of the top five deals are also online only:

  • Npower Energy Online, £1155.73 per year, fixed until October 2014
  • Scottish Power Online Energy Saver, £1169.52 per year
  • Sainsbury’s Energy, £1172.11 per year, fixed until October 2014
