How to compare gas & electricity prices in Ireland
Switching to a cheaper gas and electricity plan can cut costs. Here’s how to make a price comparison, find the cheapest plan and switch your supplier to save hundreds of euros.
Why compare suppliers?
If you haven’t changed your energy provider in the last 12 months, there’s a good chance you could save money by switching.
Many electricity and gas suppliers offer discounts to new customers for the first year, but when this discount period ends, you’ll pay the standard rate, which is often higher.
It doesn’t pay to be loyal to your energy supplier, so it’s worth comparing plans and switching to a better deal when your contract ends.
How much could you save?
The average electricity customer could save up to €455 a year by switching from a standard tariff to the cheapest deal on the market, and the average gas customer can currently save up to €343 by moving to the cheapest deal.
If you’ve not switched for over a year, you’ll be out of the discounted period and paying more than you need. You’ll save even more by switching gas and electric if you have a dual fuel tariff.

What is smart plan?
A smart tariff is an energy plan that charges different rates for electricity depending on the time of day, and sometimes the day of the week.
Unlike traditional plans with constant pricing, smart electricity tariffs offer time-of-use prices to reflect changes in demand and supply throughout the day.
To make use of a smart plan, you’ll need a smart meter installed on your property.
Are they cheaper?
To benefit from a smart tariff and cut your energy costs, you need to shift much of your energy use to cheaper off-peak hours.
Bear in mind that if you can’t shift usage due to family or work commitments, higher peak rates might make a smart tariff more expensive than a flat-rate plan and you might end up paying more.

How do you choose between offers?
The right energy plan for you depends on your household size and the amount of power you use. For example, if you live in a:
- Large household with high usage: A big discount may work best because it significantly reduces your bills over the discount period.
- Small household with a lower-than-average use: A smaller discount that offers cashback or a welcome bonus upfront could offer better value.

What information do you need to switch?
To switch your energy supplier you need:
- Your most recent gas or electricity bill
- Your Meter Point Reference Number (MPRN)
- Current meter readings
You’ll need a smart meter if you’re switching to a smart plan. You’ll also need adequate mobile reception, for meter connectivity and interval readings.
How long does it take to switch energy supplier?
It usually takes 7-14 days for your switch to be carried out. The exact time it takes for your switch to be completed depends on the supplier; however, it shouldn’t take any longer than 28 days.
What about switching to a smart plan?
If you’ve recently had your smart meter installed, it can take up to 30 days to connect and run half-hourly interval readings required for time-of-use plans, which offer discounted rates at certain times of the day.
Before switching, it’s a good idea to monitor your current energy usage first, so you can choose the best smart plan that suits your needs.
Remember, once you move to a smart plan, you can’t switch back.

Popular questions
What is a dual fuel plan?
A dual fuel tariff means you get your electricity and gas from the same energy supplier.
These plans are typically cheaper and more convenient because they’re from one energy supplier, so you’ll only get one bill.
You may get a discount when you sign up for gas and electricity together. Currently, if you have gas and electricity, you could save up to €776 by switching.
What is a fixed-term contract?
Most energy plans in Ireland are fixed-term contracts for 12 or 24 months. Suppliers usually offer an introductory discount for the same time as the fixed term.
You can revert to their standard tariff when your contract ends or switch to another supplier.
If you leave your contract early, you’ll normally have to pay an early exit fee of between €50 and €100.
Should I trust Switcher.ie to compare gas & electricity deals?
Yes, Switcher.ie is accredited by the Commission for Regulation of Utilities (CRU), which means we are endorsed as an independent, impartial and accurate source of information for energy customers.
How do I know when my discounted tariff is ending?
If you switched more than 12 months ago, you may have reverted to the standard rate.
Check your bill or online account to find the name of your current tariff. If you’re unsure, you can always contact your supplier to find out.
If you’ve been on the same tariff for three years or more, energy suppliers should give you 30 days’ notice before their discount ends and an annual prompt.
What is the average gas and electricity bill in Ireland?
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.
The average annual electricity bill for a customer on a standard tariff would be €1,752, while a gas customer on a standard tariff would pay €1,498.
So, if you live in a three-bedroom house, your electricity usage is likely to be similar to the national average, but if you live alone in a one-bedroom apartment, electricity costs will be lower.
Can you get a cheaper tariff with a smart meter?
Smart meters give you access to Time-of-use plans, which offer discounted energy at certain times of the day. However if you don’t shift your energy consumption to off-peak hours, you could end up paying more.
Before switching to a smart meter plan, it’s a good idea to get insights into your energy usage first, so you can monitor your habits and choose the best deal that suits your needs.
