GB Energy Supply offers the cheapest dual fuel deal on the market in August

Each month we scour the energy market to bring you the top five cheapest energy deals. For August, we've uncovered two deals available to all for less than £900 a year, as well as a selection of new localised energy deals that offer competitive prices only to those living in certain areas.

The cheapest widely available deal on the market, the Premium Energy Saver tariff from GB Energy Supply, comes in at £870 a year. That's nearly £300 cheaper than Npower's standard tariff.

Which? Recommended Provider Ovo Energy is still competitively priced at £918 a year for its Better Energy (online only and paperless) deal.

Ovo is the only Which? Recommended Provider for energy companies - this means that it meets our criteria according to our thorough policy, practice and pricing analysis.

Current standard tariffs from the Big Six

Most households are still on a ‘default’ standard variable tariff. These are generally a lot more expensive than cheaper fixed deals. If you're on one of these tariffs, you are paying too much.
