You would think so from everything you read so we decided to analyse the market to find out. At Zog we are committed to consistently low prices at rates that are considerably cheaper than the larger suppliers. Having checked our tariffs against other suppliers offering dual fuel discount and single fuel electricity prices we have proved that for average usage cheaper prices are still available if you use different suppliers for gas and electricity. Remember that if you have a dual fuel discount at present this will have already been included in the calculations when you input your usage details on the comparison sites. In most cases this will have shown a saving even after the dual fuel discount has been applied which shows how much cheaper we are! However as individual's circumstances vary we would always recommend customers review individual suppliers prices to ensure that you fully understand the impact on any dual fuel tariff you may currently be paying.
