A kilowatt-hour (kWh) is a unit of measurement for electricity usage. It represents the amount of energy consumed when a 1,000-watt (1 kW) appliance runs for one hour.
For example:
A 100-watt light bulb running for 10 hours uses 1 kWh.
A 2,000-watt (2 kW) electric heater running for 30 minutes uses 1 kWh.
Your electricity bill is based on the number of kWh you use each month, along with other charges like the unit charge and standing charge. Reducing your energy consumption—for example, by using energy-efficient appliances or shifting usage to off-peak times—can help lower your electricity costs.
With a standard plan you pay one unit rate, during peak and off-peak times. With a smart meter, you can choose from a flat rate with the same cost at any hour of the day, or benefit from time-of-use pricing — meaning the rate you pay can vary throughout the day or on the weekend.
By shifting your usage to off-peak hours, you can significantly lower your energy bills.
Smart meters automatically send readings, so all bills are based on actual use, not estimates. Easy!
You’ll get loads of useful insights into your energy usage if you then switch to a smart plan. For more information on smart meters, see our smart meter guide.
If you have a Time of Day meter (also called a Day/Night Meter), you’ll be charged different rates during the day and night. During the day, you’ll be charged a higher rate between 8am and 11pm. You’ll be charged a lower rate at night between 11pm and 8am.
You’ll see the two different rates on your bill, listed as ‘day units’ and ‘night units’ in your bill breakdown.

Eligible customers will have had the second credit applied to their account by 9 January 2025.

It's more cost effective to drive an EV (electric vehicle) than a fuel-based car. The exact cost depends on your driving needs, car efficiency, and how many miles you drive.
On average, an EV owner charges their EV at home approximately 80% of the time which may add up to 3,000 kWh or more to your electricity bill. If you’re driving your EV 17,500 km per year and sign up to our Smart EV plan, it’ll cost you approximately €180 annually (excluding your household electricity bills), i.e. approximately €1 per 100kms.
