New cheapest energy deal: what you need to know

Think twice before switching to Spark Energy

New cheap deal from Spark Energy

Spark Energy has launched the cheapest gas and electricity deal on the market – but price isn’t the only thing you need to consider when choosing an energy company.

The Spark Energy Spark Advance 2 costs £1116.41 for an average gas and electricity user – £23 less than the next cheapest deal, the M&S Energy Fix & Save at £1139.43.

However, energy regulator Ofgem is investigating Spark Energy because of complaints about billing issues, complaints handling and customer switching – so you may want to take more than the price into account when deciding whether or not to switch. 

To find out which gas and electricity suppliers customers are most satisfied with, see the results of our energy companies satisfaction survey. We don’t have a customer satisfaction score for Spark Energy yet, due to it’s small size.

The five cheapest dual fuel tariffs currently available for the average home are:

  • Spark Energy Spark Advance 2: £1116.41
  • M&S Energy Fix & Save: £1139.43

  • Sainsbury’s Energy Online October 2014: £1172.11
  • Npower Online Price Fix November 2014: £1182.03

None of these companies top our satisfaction survey.

The Spark Energy tariff is a variable price tariff with a minimum 12-month term, and cancellation fees of £60 for leaving before that.

Worried about gas and electricity prices?
