If you prefer to browse current prices yourself, we've already compared current electricity and gas prices to find you the cheapest packages available today.

Note that in this guide we use the Estimated Annual Bill (EAB) for an Urban 24-hour tariff to compare electricity and gas prices from each supplier.

What is the EAB?The EAB indicates an estimated cost of your energy using Ireland’s average household electricity and gas consumption. The CRU is the organisation responsible for establishing the EAB figures which each energy supplier needs to follow. The current amounts used are 4,200 kWh for electricity and 11,000 kWh for gas.

Calculate the prices with our complete energy provider pages

If you prefer, you can also get out your calculator and dive down into your current bill and compare it against other providers' offers. We have listed the complete details on each provider's tariffs, charges, reviews, and more so you can easily do it yourself.

To compare electricity and gas prices, there are a few things you’ll need to know and some items to have on hand to make the whole process easier. You’ll need:

  • A recent bill from your energy supplier (to see unit rates and standing charges).
  • A smartphone, tablet, or computer to check current unit rates and offers with other gas and electricity suppliers.
  • A calculator.

You can calculate your household consumption by looking at your bills over a yearly period and adding up your usage in kWh (kilowatt-hours). You can then use this figure to calculate your consumption costs.

We give you further step-by-step information on how to calculate your estimated bills so you may compare gas and electricity prices yourself.

How do I compare electricity prices?

If you want to compare electricity prices from different suppliers yourself to find the cheapest electricity rates, you will need to have the following five elements;

A green lightbulb
  1. Your yearly electricity usage
  2. Electricity unit rate
  3. Standing charge
  4. PSO levy
  5. VAT

We suggest you first calculate your annual electricity bill amount based on your current rates and tariff.

You can then use your current electricity prices as a guide to compare electricity prices against the various providers’ offers. This also applies to Pay As You Go (PAYG) customers.

Anyone with discounted hour rates should tally the day, night, and peak hour usage for the year to get an accurate price.

We look at each item in detail below in our easy six-step process to compare electricity prices.

Step 1 - Calculate your current electricity usage

Add up your electricity usage in kWh by looking at your bills over a yearly period (regardless of whether you switched suppliers in the same period).

If you are on any discounted rate according to time of day, your bills will show you the usage during the various time frames.

Use these figures to calculate your electricity consumption and therefore get an accurate price comparison.

If you do not have your electricity usage, you will need to use the national average consumption figures to compare. The current average consumption in Ireland is 4200 kWh.

Step 2 - Determine your electricity tariff

You then need to determine the type of tariff you have for your home. The choices are:

  • Urban 24 hour
  • Rural 24 hour
  • Urban Nightsaver
  • Rural Nightsaver
  • Smart Meter Tariff

If you are on a standard 24-hour tariff you will have just one unit rate on your bill.

You can determine if your home is considered urban or rural by looking at your electricity MPRN number on your bill. The letters ‘DG1’ indicate an urban rate designation whereas ‘DG2’ are rural rates.

If you are on a Nightsaver tariff, you will need to divide between the day and the night unit rates.

Smart meter tariffs have three rates (T1, T2, and T3) usually with the following time frames;

  • Day rate (8am to 5pm & 7pm to 11pm)
  • Night rate (11pm to 8am)
  • Peak rate (5pm to 7pm)

Step 3 - Divide your electricity usage

Once you know how much electricity you are using and the tariff that applies to your home, you are ready to start determining your yearly electricity cost.

Should you not have your household yearly usage and are using the national average consumption of 4200 Kwh to compare electricity prices, here is how you want to break up the electricity used to make the calculations:

  • For a standard 24-hour tariff, you will have just one unit rate on your bill and multiply it by the national average of 4200 kWh.
  • For Nightsaver rates, you will need to calculate your unit rate by multiplying your night unit rate by 1,050 (one-quarter of the average usage rate of 4200), and your day unit rate by 3,150 and add the two resulting figures.
  • For Smart meter rates, you will need to calculate your unit rate by multiplying your night unit rate by 1,007, your day unit rate by 2,658, your peak time rate by 535, and then add the three resulting figures.

Of course the more electricity usage you move to Nightsaver hours, the more you could save. This is why it is so important to know your household energy usage when you compare electricity prices.

As an example, someone working night shifts will have a much higher daytime electricity usage over night time when they are away from home. Such a Nightsaver rate may not be in their best interest.

On average, nightsaver or smart meter rates will start to be beneficial over 24 hour urban rates if you use at least 25% of your electricity at night time.

Step 4 - Calculate your electricity standing charges

Once your energy usage costs have been calculated, you still need to add the standing charges on top of these amounts.

The PSO levy is the Public Service Obligation levy. It is used to subsidise renewable and indigenous energy development in Ireland. Once a year, the government determines the PSO amount. It is currently €58.57 including VAT until October of 2022. This amount is the same for all suppliers in Ireland.

You will also need to add the provider's standing charges according to the tariff you will have.

Finally, you need to add the taxes. Like gas, VAT on electricity is set at 13.5%.

Step 5 - Count the various electricity costs

To simplify matters on how to count the total electricity costs, we use the following example below.

Let's take a standard urban 24-hour tariff with no discounts or welcome credit and an electricity unit rate of 17.39 cents per kWh. To determine your annual electricity cost, you would do the following calculations:

Electricity

Annual Amount

Unit rate

(€0.1739 x 4200) + 13.5% = €828.98

Standing charge

€147.75 + 13.5% = €167.70

PSO levy

€58.57

Total

€1055.25

To calculate how much your bill would be with discounts or credit offered by energy suppliers for new customers, repeat the above calculations but apply the discount to the unit rate and subtract any welcome credit from the total amount.

For example, a 20% discount and a 210 Euro cash back credit on the above standard 24-hour tariff would make for the following calculations:

Electricity

Annual Amount

Unit rate

(€0.1739 x (100-20%) x 4200) + 13.5% = €663.19

Standing charge

€147.75 + 13.5% = €167.70

PSO levy

€58.57

Total

€889.46 - €210 cashback = €679.46

Step 6 - Repeat step 5 to compare electricity prices

Once you have determined your current annual electricity cost with the above 5 steps, you simply need to repeat the last step with the pricing of the new provider you are looking to compare electricity prices.

Whichever has the lowest annual cost is your cheapest electricity provider for your home.

How do I compare gas prices?

Similar to electricity, you will need to have the following five elements to compare gas prices from different suppliers and find the cheapest gas prices in Ireland;

A gas flame in a transparent box
  1. Your yearly gas usage
  2. Gas unit rate
  3. Standing charge
  4. Carbon tax
  5. VAT

We suggest you first calculate your annual gas bill amount based on your current gas rates and tariff.

You can then use your current gas prices as a guide to compare gas prices against the various providers’ offerings. This also applies to Pay As You Go (PAYG) customers.

Unlike electricity, gas does not usually come with discounted hourly rates. This makes gas prices much easier to calculate in comparison to calculating electricity prices.

We look at each item in detail below in our easy five-step process to compare gas prices.

Step 1 - Calculate your current gas usage

You can calculate your gas consumption by looking at your bills over a yearly period and adding up your usage in kWh (kilowatt-hours).

Use these figures to calculate your gas consumption and therefore get an accurate price comparison.

If you do not have your gas usage, you will need to use the national average consumption figures to compare. The current average consumption in Ireland is 11,000 kWh.

Step 2 - Determine your gas tariff

You then need to determine the type of tariff you have for your home. Gas is different from electricity as the price is not dependent on your geographical location or time of day.

The majority of homes will have the one gas rate to use to calculate its yearly cost.

To know your current gas tariff, look at your most recent gas bill and see the unit rates used per kWh.

Then, you simply need to multiply the unit rate by the amount of gas you use in a year (step 1).

Step 3 - Calculate your gas standing charges

Once you have calculated your gas usage costs, you still need to add the standing charges on top of these amounts.

Gas standing charges are divided into three categories: an annual fee from your provider, a carbon tax per kWh of gas used, and finally, the VAT.

For homes with a gas PAYG meter, the process for calculating their annual bill is the same except they will also have to add in the annual PAYG service charge.

The carbon tax is set by the government and is usually updated yearly. It is currently at 0.00688 cents, including VAT, per kWh.

The VAT is then added at a rate of 13.5%.

Step 4 - Count the various gas costs

To explain how to count the total gas costs, we use the following example below.

Using a standard gas tariff with no discounts or welcome credit, with a gas unit rate of 5.75c excluding VAT, the calculation would be as follows:

Gas

Annual Amount

Unit rate

(€0.0575 x 11000) + 13.5% = €717.89

Standing charge

€90 + 13.5% = €102.15

Carbon tax

0.00688 x 11000 = €75.68

Total

€895.72

The total above represents a standard tariff with no discounts or free credit for switching.

Discounts are usually only against the standard unit rate, not the entire amount billed. If you’ve been with your supplier for over a year then chances are you have defaulted to a standard rate tariff.

To calculate how much your bill would be with discounts or credit offered by gas suppliers for new customers, repeat the above calculations and apply the discount to the unit rate as well as subtract any welcome credit from the total amount.

For example; a 15% discount and a 120 Euro cashback credit on the above standard gas tariff would make for the following calculations:

Gas

Annual Amount

Unit rate

(€0.0575 x (100-15%) x 11000) + 13.5% = €610.20

Standing charge

€90 + 13.5% = €102.15

Carbon tax

0.00688 x 11000 = €75.68

Total

€788.03 - €120 cashback = €668.03

Step 5 - Repeat step 4 to compare gas prices

Once you have determined your current annual gas cost with the above four steps, just repeat the last step with the pricing of the new provider you want to compare gas prices with.

Whichever has the lowest annual cost is the cheapest gas provider for your home.

How do I compare electricity and gas prices (dual fuel)?

To compare both electricity and gas prices, known as dual fuel tariffs, you can calculate your current rates for electricity and gas as shown above.

The only difference with calculating a dual fuel offer is that you will need to verify whether any discounted unit rates apply to both fuels or just against one of the two.

Even though you may prefer to deal with just one provider, sometimes a better deal can be had by splitting your electricity and gas between two different providers. Therefore, it is important to check all these factors when you compare electricity prices.

If you have any further doubts about reading your utility bill or are confused by the terminology, we recommend you check out our guide to understanding your utility bill.

Did you know? Comparing your current tariffs to other electricity and gas suppliers every 12 months is the best way to save money and keep your energy bills down. In fact, the CRU recommends switching energy providers every 12 months.

Changing energy suppliers; is it worth it?

Now that you know your estimated annual bill with your current supplier, you can calculate the savings you could make by changing suppliers.

In most cases, if you have defaulted onto a standard tariff and are switching to a discounted one, you can usually save more.

With the above examples, we can see that you could save over €500 per year just by switching suppliers. With such savings, it’s no wonder the CRU recommends doing this every 12 months!

Before changing though, there are other factors you should consider apart from pricing. See our recommendations on how to switch providers for complete details.

How do I change energy suppliers?

An electricity lightbulb and gas flame in a moving box

So you’ve compared gas and electricity prices and are ready to switch suppliers. We have good news for you.

While years ago switching energy providers would have resulted in a mountain of paperwork, switching nowadays is relatively painless. You can either call the provider's customer service line or switch directly online. In some cases, you may receive a physical paper contract to sign and that’s it!

If you like the sound of one of our exclusive tariffs here at Selectra, we will handle the switch for you and set you up with a switching date. Your new energy provider will take care of the rest for you. There will be no need to contact your old provider and cancel your contract.

Warning If you are still in contract with your current provider, you may be charged an exit fee for switching. Do check the fine print of your contract or you could receive a nasty surprise with your final bill.

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.
