How monthly electricity cost is calculated
Monthly cost = monthly kWh × price per kWh + (daily standing charge × days)
Example: 225 kWh at 25p per kWh is £56.25. Adding a 50p daily standing charge over an average month (about £15.21) gives an estimated £71.46.
Finding your monthly usage
Your bill or online account normally shows the kWh used in each billing period. If your bill covers a different number of days, divide by those days and use the daily calculator instead.
