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.

How much can save with a smart meter plan?
A typical household using mostly energy during off-peak hours (at night, and outside of 5pm-7pm) could save up to €587 a year if they switched from a standard, non-smart plan to the cheapest smart tariff on the market.
If you own a smart meter, smart meter plans offer discounted energy at certain times of the day and night, rewarding households who can shift their energy use to off-peak periods, when electricity is in less demand.
Although smart tariffs can offer big savings, they could also cost you more if you don’t change your consumption habits. Once you move to a smart plan, you can’t revert to a standard plan.
