A Request for Service Requires a Credit Application

Protecting your personal information and credit is very important to us.

A credit application helps us determine if a deposit is needed from new customers. This also helps prevent unauthorized changes to an account. Federal Law (the Fair and Accurate Credit Transactions Act) requires us to use rigorous measures to identify, detect, and lessen the chance of identity theft.

Security Deposit Setup Fees

For Residential Customers

There is a $25.00 setup fee to open a residential account. A security deposit may be required when starting service. However, residential customers have a choice of a Pre-Pay account that requires no security deposit. Account deposits are credited back to the residential account after 12 months of excellent payment history.

For Commercial Customers

Commercial customers are charged $25.00 to open an account. They must provide a security deposit, which is applied when the account is finalized.

Security Deposits

Deposit amount may equal an estimate of two times the highest bill.
Check out the complete list of our fee and rate schedules.
