Dear [tenant's name],
We are writing to inform you that, following the reduction of power supply which occurred last summer as a consequence of the late payments, the electric company (Enel) requires a new contract to be signed. This is a part of the standard reactivation procedure in such cases. Presently supply takes place under a temporary contract. The new contract must anyway be signed by us, after which we might put it in your name (e.g. if you would be interested in paying the bills by direct debit or by credit card). The charges, including a security deposit, are € , .
Besides, since [date] we are paying the telephone bills, as [tenant's friend] refuses to do so on the grounds that she is not using the telephone or internet. Of course, if you prefer, we may choose to terminate the contract with the telephone company (Wind), which is presently in our name.
We would appreciate your immediate attention to these matters.
Sincerely yours,
[landlord]
