What is a unit of electricity?

One ‘Unit’ of electricity, also known as a kilowatt hour (KWh), is 1000 watts of electricity used for one hour. Your energy supplier will show how many units of electricity you have used on your bill, but our electricity calculator also works this out based on your meter readings.

What is a Daily Standing Charge?

The daily standing charge is the price you pay per day to receive your electricity from your supplier. This is like a connection fee or landline monthly line rental and is separate from the price you pay for your actual electricity usage.
