It is whether measured kWh changed. If electricity use rose, investigate the apartment and equipment. If usage stayed similar but the total rose, investigate billing days, price components, fixed charges, fees and adjustments.
1. Confirm how the apartment is billed for electricity
- Direct utility account: the electric utility bills your dwelling unit and reports measured usage for the account.
- Property submeter: the property or billing company issues the statement but uses unit-level measured consumption.
- Allocation / RUBS: the property divides a larger utility expense using a disclosed weighting method instead of billing only your measured kWh.
- Unclear landlord-billed charge: the statement does not show enough meter or formula detail to reconstruct the amount yet.
2. Compare kWh and billing days before comparing dollars
Put the current statement beside a prior statement for the same account or unit. Compare service start/end dates, total billing days and kWh. A longer period can produce a higher total even when average daily use changed little.
- If kWh increased materially, move to the usage side: HVAC, water heating, appliances, equipment or an unusual occupancy pattern.
- If kWh stayed similar, move to the billing side: rate components, delivery/customer charges, taxes, fixed fees or adjustments.
- If the bill does not show kWh, confirm whether it is actually submetered or allocated before using an electricity-consumption explanation.
3. If kWh jumped, check heating and cooling first
For a measured electric bill, heating and cooling can change sharply with weather, thermostat settings, airflow and equipment operation. The U.S. Department of Energy publishes renter-focused guidance that includes heating/cooling, thermostat, air-leak, filter and appliance checks.
- Was the period much hotter or colder than the comparison period?
- Did thermostat settings or occupancy change?
- Was a filter clogged or airflow restricted?
- Did a portable heater, portable AC, dehumidifier or other high-use device run more often?
- Was HVAC or water-heating equipment malfunctioning or running continuously?

4. Check the meter reading and whether it was estimated or corrected
Read the meter section of the statement. If the utility identifies a reading as estimated, compare the next actual reading and any adjustment line. A later correction can produce a catch-up charge or credit that makes one bill look unusually high even though part of the amount belongs to an earlier period.
The sequence of reading dates, estimates, actual reads, credits and rebills is often more useful than the final total alone.
5. Separate energy charges from delivery, customer and other fixed charges
An electric statement can include more than a consumption charge. List each identifiable component separately: energy/supply, delivery or distribution, customer/basic charge, taxes or government charges, property billing fees, prior balances and adjustments.
This matters because the total can rise while kWh barely changes. A fixed or administrative fee is a different question from measured electricity use and may require a lease or state-rule review instead of an energy-efficiency diagnosis.
6. Do not treat a RUBS electric charge like a meter bill
If the property uses an allocation formula, your household may be paying a share of a property-level electric expense rather than only the kWh measured inside the apartment. In that case, the important records are the source expense, the resident allocation pool, the weighting formula and your household input.
Use the actual lease/addendum and state rule before assuming that a particular electric allocation method is permitted. Utility billing frameworks differ significantly by state and sometimes by utility type.
7. Treat the first bill after move-in separately
A first electric statement may contain a partial or unusually long service period, service-initiation charges, a deposit, an opening meter read or a delayed property billing cycle. Do not use it as a clean monthly baseline until those one-time and timing items are separated.
8. Preserve maintenance evidence when the apartment itself may be driving the usage
If measured kWh increased and you suspect malfunctioning HVAC, a water heater, refrigerator or another building-provided system, save maintenance requests, technician notes and the dates of any repair. Compare bills before and after the repair when possible.
The goal is not to prove the equipment caused the bill from one statement. It is to create a timeline that can be compared with the measured usage change.
9. Gather the billing evidence before asking for a correction
- Current and prior electric statements.
- Service dates and billing-day count.
- kWh and beginning/ending readings when shown.
- Actual/estimated reading status and any rebill history.
- Lease and utility addendum.
- Separate delivery, customer, admin and adjustment lines.
- Maintenance records for suspected HVAC/electrical problems.
- Any notice of rate, method or fee changes.
10. Match the remaining question to the exact state or provider rule
The federal renter-energy guidance helps diagnose measured consumption, but it does not decide whether a landlord or billing company may allocate electricity, add a fee or use a particular submetering arrangement. Those questions can depend on the state, utility type, lease and regulator.
RentBillCheck currently publishes 20 dedicated state utility source layers where an exact rule has been verified. If your state is not listed, use the document workflow without borrowing another state’s rule.
Frequently asked questions
Why is my apartment electric bill suddenly so high?
Start by separating measured electricity use from the dollar total. A higher bill can come from more kWh, a longer billing period, a rate or fixed-charge change, an estimated or corrected reading, an adjustment, or a landlord/third-party billing method. In an apartment, first confirm whether electricity is directly billed, submetered or allocated.
What should I compare first on two electric bills?
Compare service dates, billing days and kWh first. If kWh rose, investigate usage drivers such as heating, cooling or equipment. If kWh stayed similar while dollars rose, focus on rate components, delivery/customer charges, taxes, billing fees and adjustments.
Can air conditioning make an apartment electric bill jump?
Yes when the apartment is billed from measured electricity use. Heating and cooling are major controllable loads in many homes, so weather, thermostat settings, airflow, filters and HVAC operation can matter. Those factors do not explain a pure RUBS allocation or a separate billing fee by themselves.
What does estimated versus actual reading mean?
Some electric statements identify a meter reading as estimated or actual. An estimated period can later be corrected when a new actual reading is available, which can create a catch-up or credit. Save both the original and corrected statements and compare the reading dates.
Can an apartment use RUBS for electricity?
Some multifamily properties use allocation methods for utilities instead of unit-level direct utility accounts. The exact method and whether it is permitted or restricted depends on the lease, utility arrangement and applicable state or local rules. Do not assume one nationwide rule.
What records should I keep before disputing a high electric bill?
Keep the current and prior statements, service dates, kWh, meter or submeter readings if shown, the lease and utility addendum, separately stated fees, any estimate or adjustment history, and maintenance records for suspected HVAC or electrical problems.
