What is the Average Electricity Bill in Ireland ?

When householders start looking into the high cost of electricity – it can be useful to compare their electricity to other households. But – what is the average electricity bill in Ireland in 2021 ?

We all use electricity in our homes – and electricity bills can make up a big part of annual household expenditure. Overall, electricity usage per appliance is dropping as modern appliances become more energy efficient. But the increasing number of electrical gadgets and appliances in our homes is also helping to keep the average electricity consumption high.

The most recent electricity usage figures for Ireland, produced by the Commission for Regulation of Utilities (CRU) ,  say that 4200kWh is now the “official” average annual electricity usage for households in Ireland. (Reference)

How Much is Electricity in Ireland ?

Based on “standard” charging rates from the biggest provider – Electric Ireland – the average usage of 4200 kWh electricity a year would result in an annual electricity bill of €1098

Electric Ireland charges 19.90c  per kWh,  including VAT. March 2021) .
(Urban 24 hour rates , Inclusive of VAT PSO and standing charges.)

This would work out at as : –

  • an average annual electricity bill of €1098 or
  • an average of €183  for each 2 monthly bill.
  • an average of €91.50 if you pay monthly by direct debit.

If you live in a rural area, you can expect to pay about €30 to €50 more per year than this for average usage.  See a comparison of Rural Electricity Charges here

How much does 1 Kwh of Electricity cost in Ireland?

One “unit” or one KwH of electricity costs about €0.26  (inclusive of taxes, PSO levy and standing charges).
This figure is based on the annual usage of 4200 units at Electric Ireland’s standard rates.

It’s interesting to see that a 100% increase in electricity usage from 2100 kWh to 4200 kWh results in overall electricity bills only increasing by 62%.  This anomaly is because a large part of the bill is made up of standing charges.

Which Appliances Use the Most Electricity?

A “unit” of electricity is 1kwh and costs about 20c.

One Kwh or “one unit” is the amount of energy you would use if you kept a 1,000 watt appliance running for an hour:

Here are some calculations of how long it would take for various appliances to use 1 kWh and cost you about 20c

  • Using a 10,000-watt electric shower for six minutes
  • Keeping an immersion heater (3,000 watts) on for 20 minutes
  • Cooking in a 2,000-watt oven for 30 minutes.
  • Tumble Dryer – running for 30 min (will vary – see Tumble Dryer Usage
  • Ironing with a 1,500 watt iron for 45 minutes.
  • Using a dishwasher for about an hour (1,000 – 1,500 watts)
  • Watching a plasma TV (280 – 450 watts) – about 3 hours
  • Keeping a fridge-freezer (200 – 400 watts) on for about three hours
  • Keeping an electric blanket (130 – 200 watts) on all night.
  • Using a laptop (20 – 50 watts) all day
