The fixed supply change is not included. Electrical appliance costs are based on watts or kilowatts of electricity consumed. (One unit = 1 kWh - 1,000 watts operating for 1 hour). If the appliance has a temperature controller or thermostat, then the setting of that control also affects the running costs.

Your household energy consumption will vary depending on the type, size, age and use of appliances, the size, insulation and layout of the home and the number of people living in the home. This means the actual amount shown may vary from household to household.
