Generally, meters are read monthly for electric, natural gas and water services, and monthly bills are generated for phone services. Bills generally must include the date on which the current bill becomes delinquent.
The meter readings for gas, electric and water services are used to determine usage for the billing period. For electric, natural gas and water service, bills must generally show the meter readings at the beginning and end of the billing period, the date of the meter readings, the amount of electricity, gas or water used, and any other information used to compute the bill. Sometimes an estimated bill will be sent to a customer if circumstances prevent the company from reading a utility meter. Any estimated reading will be clearly noted on the bill and will be adjusted the next time the meter is able to be read.
For telephone service, bills must include the amount due, first and last days of the billing period, and any other information used to compute the bill.
