Which is correct: electric bill, electrical bill or electricity bill?
"Electric bill" implies that the bill runs on electricity. "Electric" is used to mean that something uses electricity, and therefore would be inapprorpiate in this context.
"Electrical bill" is a bill that is concerned with electricity, and so would be appropriate.
An "Electricity bill" is a bill paying for electricity, and I believe this is the best option, (as do most electricalelectricity companies.)
To sum up, "electrical" and "electricity" are both appropriate in this context, and personally, I think "electricity bill" is the best option.
