More Switching Tips

Tip: All households also use electricity – and you can usually get a better overall deal if you get both your gas and electricity from the same supplier.
See our page on Dual Fuel Bundles Compared

Be aware that the Irish energy comparison sites don’t all include cashback offers when calculating the total annual charges.  So, don’t assume that the supplier they show at the top of their list will actually be the best deal for you. You might need to add on any cashback offers to work out the total savings over 12 months. (We have done that for you in the table above)

12 months after switching your gas supplier you should always look at switching again to get the best deal. It only takes a few minutes .
