David in order to answer your question accurately I would need your post code but as your consumption is very near the average for both Gas and Electricicy I suspect that the best dual fuel deal for you would be B Gas or Spark and you could probably save about £250 a year. You can also earn a £30 cashback from Moneysupermarket if you choose a product that you can apply for via our site. I suggest you use our comparison service to find the best available dual fuel deal. Enter your post code, your consumption levels, your current payment method and the results table will give you the answer that you are looking for. Our claculator takes account of all the various unit prices from all the suppliers. Good Luck Paul
