While you have the phone in your hand, why not use it to save a bucket load on your gas bill? While Bord Gais are far cheaper than ESB for electricity, for Gas they're positively extortionate.
If you switch to Flogas you can save up to 20 per cent on your natural gas, which could save you a whopping €160 on the bill for the average home over the space of a year. As with switching your electricity it can all be done simply and quickly over the phone.
Best: Flogas €640 per year
Avoid: Bord Gais €800 per year
