"Call the utility 30 days before you move." Half-true.
Two parallel countdowns run inside every US move, and almost every checklist conflates them. The first is the utility countdown: a single phone call at each end, legally capped at about 3 business days notice in most state PUC tariffs. The second is the supplier and household countdown: 30 days of comparison shopping, paperwork, credit checks and assistance-program transfers that the utility cannot do for you.
If you call your utility 30 days early, the agent will record the date and pull it up again on day T-3 when the system can actually act on it. The 30-day rule survives in checklists because it is roughly correct, not because the utility needs that much time. Knowing which countdown each task lives on saves a fortnight of unnecessary worry, and prevents the supplier compare from getting skipped at the end.
What 30 days actually buys you.
Three concrete tasks fill the gap between "ample notice" and "wasted time". Each one needs lead time the utility itself does not.
Compare suppliers in deregulated states
In 18 retail-choice states plus DC you choose the supplier separately from the utility. A reasonable compare across 2-3 fixed-rate plans takes about a week: pulling each Electricity Facts Label (REP in Texas, ESCO in NY, ARES in IL), checking the post-introductory rate, confirming the supplier is licensed at the new ZIP code. Skip this and you default to the utility-default rate, which is usually the worst rate available.
Request a deposit waiver via credit check
Most utilities will waive the security deposit (commonly $100 to $300) if your credit score clears their threshold. The check is fast in principle, but disputes, frozen files and identity-verification holds can take 7-10 days to resolve. Starting the credit-check request early means the waiver paperwork is on file before the move-in date instead of being settled after the first bill arrives.
Transfer LIHEAP, EAP or PIPP enrolment
Federal LIHEAP and state-mandated discount programs (EAP in NY, PIPP in Ohio, similar elsewhere) follow the household, not the address. The transfer requires written notice to the state office and the new utility within 30 days of the move. Miss the window and the benefit lapses, sometimes for the rest of the program year.
The 30-day countdown, side by side.
One row per checkpoint, three lanes: the utility call (short, legal), the supplier task (deregulated states only), and everything else (movers, internet, USPS, assistance). Read down the lane that matches your situation.
| When | Utility task | Supplier task (deregulated states) | Other |
|---|---|---|---|
| T-30 | Look up the delivery utility for the new address. Note customer-service line and outage line. | In deregulated states, shortlist 2 suppliers (REP / ESCO / ARES). Read each Electricity Facts Label. | Confirm closing or lease date. Request paid time off if the move is mid-week. |
| T-21 | Check whether a deposit will be required at the new address. Request a credit-check decision in writing. | Ask each shortlisted supplier whether they serve the new ZIP code and at what fixed rate. | Book the moving company. Renters: confirm landlord paperwork and proof-of-residence requirements. |
| T-14 | Open the new account by phone. Have full name, SSN, move-in date and service address ready. | Enrol with the chosen supplier so the contract starts on the move-in date, not the utility default. | File a USPS change-of-address. Schedule internet install and trash pickup at the new address. |
| T-7 | Notify LIHEAP / EAP / PIPP if you receive bill assistance. Benefits follow the household, not the meter. | Confirm the welcome packet and contract start date in writing. Save the email confirmation. | Update auto-pay billing on any account that follows you (insurance, banking, subscriptions). |
| T-3 | Call the outgoing utility to close service. This is the legal-minimum business-day window in most states. | Notify the outgoing supplier of the move-out date in writing. Request the move-out exemption on any early-termination fee. | Forward the final-bill mailing address to the closing utility. Renters: send the landlord written move-out notice. |
| T-1 | Confirm the close date and the open date by phone. Get a confirmation number for both. | Verify the new supplier contract is active for the move-in date and rate-locked at the quoted price. | Pack the camera or phone you will use for meter photos. Charge it. |
| Day 0 | Photograph both meters (old and new) with a clear timestamp. Note the kWh and therm readings. | Save the photo of the new address meter against the supplier contract start kWh. | Hand over keys, log final landlord walk-through, retain a signed copy. |
| T+5 | Review the final bill from the outgoing utility. Cross-check the meter read against your photo. | Confirm the first bill at the new address shows the contracted supply rate, not a default-service rate. | Update the address on driver licence, voter registration, banking and tax records. |
| T+30 | Claim the deposit refund if one was paid at the outgoing address. Confirm the LIHEAP transfer cleared. | Re-read the first full-month bill at the new address. Flag any introductory-rate clauses set to expire. | Cancel forwarded mail if no longer needed. File any moving-related receipts for tax records. |
T-N means "N business days before move day". T+N means "N days after". Day 0 is the move itself. Business days only on the utility lane, calendar days everywhere else.
What goes wrong in the middle two weeks.
T-14 to T-3 is the silent zone of the checklist. The utility call has been booked, the moving company is booked, and four costly tasks quietly slip.
Skipping the supplier compare
If you live in a deregulated state and never enrol with a competitive supplier, the utility puts you on default service. In Texas it is the Provider of Last Resort rate, in New York and Pennsylvania it is the utility-procured price-to-compare. Default service is rarely the best rate available, and households can pay 15-30% more than a comparable fixed-rate offer for a year before noticing.
Missing the deposit-waiver paperwork
A credit check that clears the utility threshold waives the deposit, but the waiver is documented in writing, often within a few days of the request. If the paperwork is not on file by move-in day, the deposit is added to the first bill. Reclaiming it later means a separate dispute and a wait for the utility to re-run the check.
Missing the LIHEAP transfer window
LIHEAP and most state-mandated discount programs require notification of a move within 30 days. Miss it and the benefit lapses until the next program year. Reapplying from scratch typically means a fresh income verification, a new household interview, and a wait of 4-8 weeks.
Not photographing the final meter read
Modern AMI smart meters close out remotely, but the handover between two accounts (your close, the next tenant's open) is a recurring source of misread bills. A timestamped photo of both kWh and therm displays at the moment you leave the keys behind is the only document that wins the dispute later.
The 3-day rule, explained.
The legal minimum is fixed by state PUC tariffs. Here is what changes when you call on T-30 versus T-3.
| What changes | Call on T-30 | Call on T-3 |
|---|---|---|
| Date the utility records | Your requested move-out date, held in the system | Your requested move-out date, scheduled for execution |
| Earliest the system can act | T-3 (it waits 27 days before doing anything) | T-3 (immediately scheduled) |
| Risk of needing to reschedule | Higher (lease and closing dates drift) | Lower (the move date is locked) |
| Risk of forgetting the call | Lower (done early) | Higher (one more last-minute task) |
| Final-meter-read mechanism | Same (AMI remote or technician visit) | Same (AMI remote or technician visit) |
Why utilities cannot pre-schedule beyond a few days
Most state PUC tariffs include a clause that limits how far in advance the utility can commit to a final meter read or service end date. The tariff treats every close as conditional on tariff rates and service terms that may change before the move date, so the utility wants the request inside a window short enough that those terms cannot shift materially.
The practical effect: an agent will happily record your move-out date in May for an August move, but the work order will not flow to the field or smart-meter system until a few business days before. That is the entire reason the "30-day rule" is a checklist convention, not a utility deadline.
Phone, paperwork, photo. What every utility asks for.
The close-of-service call is short, structured and identical across the country. Have four pieces of information ready and the call is under 10 minutes.
Full name + SSN
The Social Security Number is used for identity verification and to pull the credit check that decides the deposit waiver. No SSN? An ITIN or a state ID with a co-signer is the usual alternative.
Move date
Business days, not calendar days. Friday and Monday moves cost an extra weekend in the buffer. The agent will read it back to you, confirm it matches your lease or closing date.
Forwarding address
The final bill and any deposit refund check go here, not to the property you just left. Skipping this is the single most common reason deposit refunds never arrive.
Account / service address
Closing: the existing account number from any recent bill. Opening: the full service address with apartment or unit number, exactly as it appears on the lease or deed.
Write these down during the call
- The confirmation number for both the close and the open work orders;
- The name of the agent and the time of the call (the recording is keyed to both);
- The exact effective date and time the utility will close the account, in writing or in the post-call email.
Four things the checklists do not tell you.
Each one shows up in reader emails month after month. None of them appear on the utility's own move page.
Default-service rates are often the worst rate available
In every deregulated state, if you do nothing the utility puts you on a fallback rate: Provider of Last Resort in Texas, price-to-compare in PA and OH, default supply in NY and MA. These rates are calibrated to recover the utility's cost without losing money, not to compete with the open market. Households that land on default service typically pay 15-30% more than a comparable fixed-rate plan available the same week.
Vacancy billing can roll the meter onto the landlord
Once your close-of-service date passes, the utility needs an active account on the meter. In many states, if no incoming tenant opens one, billing reverts to the property owner under a vacancy-billing rule. Some landlords then back-bill the prior tenant under the lease. Your defence is the email confirmation of the close date, the final meter read figure, and the date the account zeroed out.
Deposit interest is real and rarely volunteered
Most state PUCs set a minimum interest rate on a security deposit held by the utility, typically around the one-year Treasury rate. It accrues monthly and is refunded with the deposit on the final bill or after a clean 12-month payment record. The interest is small, but it is yours, and the line item is often skipped on the closing statement unless you ask.
A 30-mile move in the same state can still end your fixed-rate contract
Competitive suppliers are licensed to deliver in specific utility footprints, not entire states. A move across the line between, say, Con Edison and PSEG Long Island, or between Oncor and CenterPoint, ends the supply contract because the supplier is not licensed at the new utility. The move documentation triggers the early-termination-fee waiver under most state PUC rules, but you have to request the waiver in writing.
What to actually do, in order.
Six tasks. The utility call is task 6, not task 1. Everything else needs to happen first.
Find your delivery utility
The ZIP code decides this, not your choice. Use the utility directory by state to confirm who serves the new address.
Get a credit-check decision early
Request the credit check on T-21. A clean decision waives the deposit; a hold needs a week to resolve.
Pre-shortlist 2 suppliers
In deregulated states, read each Electricity Facts Label or Customer Disclosure Statement. Confirm the supplier is licensed at the new ZIP. Compare the post-introductory rate, not the teaser.
Notify LIHEAP / EAP / state assistance
Within 30 days of the move. The state office links your household ID to the new utility account. Call LIHEAP or dial 211.
Photograph both meters on Day 0
kWh and therm displays at both addresses, timestamp on. This is the only document that settles a disputed final bill.
Schedule the 5-day buffer call
Five business days before the move, call the outgoing utility to close and the incoming utility to open. Get a confirmation number for both.
Eight quick answers before you call.
The published minimum across most regulated state Public Utility Commission tariffs is 3 business days. New York (16 NYCRR Part 11), Pennsylvania (52 Pa.Code §56) and Massachusetts (220 CMR 25.00) all codify a 3-business-day floor for residential disconnections. Older non-smart meters that need a manual final read can push the window to 5 business days, which is why 5 days is the comfortable target. Calling earlier than 3 days never hurts; utilities record the close date you give them but cannot act on it sooner than their tariff allows.
Because the 30 days is for everything that is not the utility. In the 18 retail-choice states plus DC you need time to compare suppliers, read each Electricity Facts Label or Customer Disclosure Statement, and enrol so the new supplier contract starts on day 0. You also need lead time to request a deposit waiver via credit check, transfer LIHEAP or EAP enrolment, and align with the closing attorney or lease start date. The utility itself can be a 3-day phone call at the end of those 30 days.
Yes, but less. The supplier-comparison block disappears (no retail choice means the utility is the only seller). Everything else still applies: deposit waiver via credit check, LIHEAP or state-assistance transfer, meter photo on move day, and a forwarding address for the final bill. Use the 30-day window for those tasks instead.
Most state PUCs have a vacancy-billing rule that rolls service onto the landlord or the property owner once the prior tenant closes. The exact mechanics vary by state, but the universal rule is that whoever last had the account in their name is responsible until the next person opens one. Keep the email confirmation of your close date and the final meter-read figure; that is the proof if the utility tries to back-bill you for the post-move-out days.
It depends on whether the supplier is licensed at the new ZIP code. A move within the same state (and the supplier serves the new utility footprint) usually transfers the contract with the same rate and term. A move out of state ends the contract because retail suppliers are state-licensed. Either way, document the move with the supplier in writing; the move-out documentation triggers the early-termination-fee waiver under most state PUC rules.
According to the US Energy Information Administration Electric Power Monthly (Table 5.6.A, March 2026 year-to-date, released 21 May 2026), the residential all-sectors average is 18.83 ¢/kWh. State averages range from about 11 ¢/kWh in North Dakota to over 41 ¢/kWh in Hawaii. Use the state average, not the national one, when budgeting for the new address.
Not automatically, but you must report the move. LIHEAP attaches to the household, not the address. Call your state LIHEAP office or county social-services agency within 30 days of the move so the grant transfers to the new utility account. Most state-mandated discount programs (EAP in New York, PIPP in Ohio, etc.) restart automatically at the new address once enrolment is linked.
The photo is your only proof if the final-bill read is disputed later. Smart meters (AMI) close out remotely and accurately, but older drive-by meters and the changeover between two accounts can produce reads off by hundreds of kWh. A timestamped photo of both kWh and therm displays, taken at the moment of the lease or closing handover, settles every dispute.
