What is the average gas and electricity bill in Ireland?

If you want cheaper gas and electricity bills, it’s helpful to understand how bills are calculated and how your energy use compares. Here’s all you need to know about energy bills in Ireland.


In May 2024, the carbon tax increased by €7.50 to €56 per tonne of C02. That means the average household will pay an extra €17 per year on their gas bill and it will now total around €122 (inc. VAT) for the average Irish household.

The carbon tax is intended to reduce carbon dioxide emissions so households using heating oil, coal, and gas to heat their homes pay the levy.

Energy suppliers in Ireland are obliged to add the charge to all customers’ bills.

How much energy does the average household use?

The Commission for Regulation of Utilities (CRU) states that the average Irish household uses 4,200 kW/h of electricity and 11,000 kW/h of gas per year.

However, other factors may mean your usage is quite different, such as:

  • The size of your home
  • How energy efficient it is
  • How many people live with you
  • When the house is occupied
  • The type & frequency of appliance use

How your energy bill is calculated

Your energy bills may look complicated, but here are the basics:

  • Energy usage is measured in kilowatt-hours (kWhs)
  • Each kWh is called a unit. The number of units you use in the billing period is shown as ‘consumption’ or ‘usage’
  • The unit rate is the cost you pay per kWh
  • The amount you pay is calculated by multiplying your usage by the unit rate

Other factors like the standing charge, levies and VAT are added to your bill to make up the total amount you must pay.

What you need to know

Here’s some of the jargon you may find on your bills with a simple explanation of what the terms mean.

  • Tariff: This is the name of your electricity, gas or dual fuel plan
  • MPRN & GPRN: The Meter Point Reference Number is the unique number assigned to your electricity or gas connection
  • Unit usage: This shows how many kWh you have used
  • Unit rate: This shows the price per kWh unit
  • Meter reading: This shows your current reading and previous reading. A = actual, E= estimated and C= customer read
  • Amount due: The total number of units used in your billing period multiplied by the price per unit
  • Standing charge: A fixed charge for providing and maintaining your energy supply and servicing your account
  • VAT: This is charged at 13.5% of your total bill and added to the final amount
  • PSO Levy: All suppliers must collect this levy from customers. It supports the generation of electricity from renewable sources.
  • Carbon emissions: This shows the kilograms of CO2 produced as a result of your energy usage
  • Carbon tax: The charge is linked to your consumption, so you’ll see the carbon tax rate on your bill as 0.01013 €/kWh (ex. VAT).
  • Conversion factor: This is the measurement that energy suppliers use to convert your gas usage into kWh.

Are your gas or electricity bills too high?

An average electricity user on the best deal in the market would pay €1,249, while a gas customer on the best deal would pay €1,189.

To get a more accurate picture of your household’s consumption, check the kWh usage from previous bills and multiple by the unit rate. This will give you a better idea of your usage and how much you can expect to pay.

How much could you save by switching?

If you haven’t switched recently, then consider changing your supplier or energy tariff.

Here’s an example of the money you could save:

  • Electricity: A user on a typical standard tariff can save up to €505 by switching to the cheapest electricity deal, and those with higher usage stand to save even more.
  • Gas: A user on a standard tariff can save up to €292 if you’re an average user and even more if you live in a large household.

This amounts to a potential saving of up to €779 if you switch from a standard tariff to the cheapest deal on the market.
