Which appliances use the most electricity?

The average Irish household uses 5,300 kWhs of electricity per year, amounting to a bill of €1,206 (based on Electric Ireland’s Standard 24 hours tariff, including taxes). It can be hard to tell how this consumption is spread across appliances and difficult to know how to make savings. A good rule of thumb is: if it makes things hot, it costs a lot.


How is electricity measured?

Electricity is measured in units known as kilo watt hours (kWh). Electricity meters record each household’s consumption and are read by ESB Networks to determine exactly how much your bill will be.

ESB Networks strives to read your electricity meter four times a year but, if this doesn’t happen (due to nobody being home, for example), an estimate based on the national average for your size of house will be used. If there’s a big ‘E’ beside the final figure on your bill, that’s how you know your consumption has been estimated.

If you think that ESB Networks’ estimate is higher than your actual consumption, you can give them a call on 1850 333 7777 to request to be billed at your actual level.


Which appliances cost the most to run?

So, how can you keep your consumption – and bills – as low as possible? Step one is knowing which appliances use the most electricity. Step two is being smart about when and how often you use them.

A good rule of thumb is: if it makes things hot, it costs a lot. Think kettles, hair dryers and electric showers – they all have a ferocious appetite for electricity.

Here’s what average Irish households of various sizes spend on a daily and annual basis:
