A reminder to everyone that Electricity(and gas) fixed term contracts only last for 12 months. You need to ring up and renew the contract to continue to receive discounts. If you don't you will move to the standard rates which can cost you an unnecessary 10-20% extra on electricity and gas adding up to €200-€300 per year to your bill.

I did not include the likes of pinergy or prepaypower as they are outrageously expensive and you cannot negotiate any discounts from them. Please stay away from these rip off merchants.
I renewed two weeks ago with Electric Ireland as they were the cheapest for me with a night rate at the time. Since then there have been two price decreases from other suppliers and I'm sure there will be more price changes over the coming months so you will need to do your own research depending on what type of meter you have.
If there's anything to take away from this it's to make sure you get your 10-20% discount and sign up for a fixed term and always remember that you have to keep renewing it every 12 months, otherwise you lose your discount.
