Higher bill? Find the cause before changing the house.
A bigger payment does not always mean more electricity use. Compare the billing period, daily use and effective price one at a time.
Check the calendar first
A five-day difference matters. Divide both bills by their billing days. Record cost per day and kWh per day; this separates a longer period from a change in household behaviour.
Look for a change in the home
Guests, working from home, an EV, electric heating, air conditioning, a pool or a new appliance can change consumption. Compare the same season when possible. A cold month is not a useful baseline for a mild one.
Check price and bill adjustments
Find any rate change, new fee, expired credit or estimated meter reading. Your effective rate includes non-energy charges, so a change in that rate is not proof that the advertised electricity price changed.
Turn the observation into a question
Use the bill increase detective to break the difference into period length, usage and effective-price effects. Keep both statements nearby. If something remains unexplained, ask your utility about the specific line item or meter reading.
