This table shows the five cheapest gas and electricity tariffs available based on the national average consumption - according to the Commission for Regulation of Utilities (CRU), the average Irish household uses 11,000 kW/h of gas and 4,200 kW/h of electricity per year.

This can give you some indication as to who the cheapest energy supplier is, but you won’t know which is best for you, and how much you’ll pay, until you run a gas and electricity comparison based on your own consumption.

How do I choose the right dual fuel tariff?

The right dual fuel deal for you will depend on a few things, including the size of your household, and your energy consumption.

If you live in a household with high consumption, the plan with the biggest discount will probably work best for you, as a rate that’s heavily discounted will make a huge difference to your bills.

Meanwhile, if you live in a small household, with a lower-than-average consumption, you might find that opting for a plan with a smaller ongoing discount that offers cashback or other bonuses up-front is more valuable for you.

There is a wide variety of plans available, so carrying out a comparison using your actual consumption, and then carefully comparing plans to see which suits best is really important.

What is the benefit of a fixed price deal?

Although not common in Ireland, there are a couple of fixed-rate energy plans out there.

With fixed rate deals, your unit rate and standing charge are set for the period of your contract, so you won’t need to worry about rising energy costs.

Last winter, the majority of energy suppliers announced hikes, which would have impacted anyone on variable tariffs, while anyone on fixed-rate plans would have been protected from the hikes for the duration of their contracts.

Fixed-rate plans are not the cheapest on the market, but if you’re worried about rising energy costs, they could offer you some peace of mind.

Will switching to the cheapest gas and electricity supplier be complicated?

Switching energy supplier is actually really straightforward - the whole process will take you less than 10 minutes.

Once you compare energy deals using our gas and electricity comparison, take a look at the details of each supplier and plan, and then choose the option that suits you best. You’ll then need to provide some information - like your address, GPRN and MPRN, and a current meter reading - to complete the switch.

How else can I cut my energy bills?

Aside from switching, the next best way to cut down on your gas and electricity bills is to reduce your consumption.

There are lots of easy ways to conserve energy in the home, including sealing off draughts, closing the curtains to keep heat in, and closing doors between rooms to prevent heat escaping. You could also switch to energy-efficient lightbulbs, which use a fraction of the electricity that standard lightbulbs use.
