How is my energy bill calculated?

In the UK, your energy bill is directly based on the amount of energy you use, as measured by your energy meters. These record your usage in kWh, which is multiplied by your unit rate and then added to the daily standing charge of your tariff to calculate your total bill. 


When you begin your occupancy your regular payment amount will be set based on an estimate of how much energy you will use, but if your energy use is more than expected your payments will be increased. Similarly, if you use less energy than expected your payments will decrease. At the end of the year, you will have paid for your exact energy usage, and any overpayment will be credited back to you.
