Several energy efficient bulbs lit up on a table

New average energy consumption values will be used from Tuesday

The new values will be used when calculating savings or annual bills for average consumers.

From next Tuesday (1 August), the consumption values used to calculate the average electricity and gas bills will change on - and across energy supplier and other price comparison websites.

In addition to this, if you carry out a gas or electricity price comparison and don’t know your actual consumption, these average values can be used to give you an idea of the savings an average household could make by switching.

The new values are:

  • 4,200 kW/h for electricity; and
  • 11,000 kW/h for gas.

This is a decrease of about 20% for both fuels, and corresponds with a drop in consumption that the CER is seeing in its market monitoring data.

Energy consumption has fallen since the financial crisis - potentially due to customers making energy-saving measures at home, and the more widespread use of energy-efficient appliances.

Research from earlier this year showed that seven in 10 people in Irish households went without heating at some point over the winter to keep energy costs down.

How will this impact me as an energy customer?

In terms of the actual cost of energy, this change will have absolutely no impact on you. However, if you compare deals using the national average consumption or look at sample bills based on national average consumption, the potential savings and annual costs you see will be lower than before.

The only way to get a truly accurate reflection of your annual bill costs - or savings you could make from switching - is to use your actual consumption data when comparing deals.

When you compare deals on, you can use the national average figures, actual consumption information from your bills in kWhs, or the amount you spend on electricity or gas in euro - so it’s really easy to see the savings you could make.

Where can I find my actual gas or electricity consumption?

Your gas and electricity consumption is outlined on your bills. If there is an ‘E’ beside this, your usage has been estimated and is not an accurate reflection of your actual usage.

Meanwhile if your meter was read, your bill will say so - you will either see an ‘a’ beside the reading, or the bill will simply state ‘Your meter was read.’

As most energy bills are for 2 months, you will need to add up the consumption or euro amount on your last 6 bills, or multiply the consumption or euro amount for one bill by 6 in order to get an idea of your annual usage or spend.
