Is Switching Suppliers Worth It?
The CRU recommends customers switch their electricity and gas providers around once a year in order to get the cheapest energy provider and the best deal. By switching regularly, you can usually save up to €500 a year on your electricity bills just from taking advantage of discount and cashback offers for new customers.
How Do I Know When To Switch?
You should look to switch your energy suppliers when you come to the end of your current contract or discount. When you go back on the standard rates, your bill automatically becomes more expensive and you’ll usually be paying much higher than before. To avoid this, you can take out another discount with your supplier, but really switching is the best way to guarantee the best deal for your household.
How Long Will It Take To Switch?
Your switch will take approximately 15 days, including a 14-day cooling-off period. During these 14 days, you’re free to cancel without any penalties and stay with your current supplier if you change your mind. Changing providers should not take more than 28 days.
