Short answer: set electricity, gas, and water to start service in your name on the day of closing (or the day before, if your lender or agent wants a buffer for a delayed close). Don't set them to start weeks early — you'll be paying to power a house you don't legally own yet — and don't wait until move-in day to even think about it, because some providers need a week or more lead time, and internet/cable can need a month. The actual calling and setting up should start about two to three weeks before closing; the actual service starting should not.

That gap — between "when you contact the provider" and "when the service actually kicks on" — is where almost everyone gets confused, and it's worth separating cleanly before you touch a single utility company's website.

The two dates that matter (and why people mix them up)

There are two different clocks running here:

  1. When you contact the provider and set things up. Do this early — 2 to 3 weeks before closing, per pretty much every moving guide out there (Zillow, LegalClarity). This is paperwork and scheduling, not service.
  2. When the service actually starts in your name. This should be the closing date itself, or the day before it if you want a cushion in case closing slips. Not two weeks before. Not the morning of move-in with zero buffer.

Confusing those two is how you end up either paying for a stranger's electric bill (you set the start date too early) or standing in a dark, waterless house you just spent your life savings on (you didn't set anything up in time at all). Both are avoidable, and both come from the same root mistake: treating "call the utility company" and "turn the utility on" as the same step.

Why starting utilities too early actually costs you money

Until you close, you don't own the house — the seller does, and legally, the seller's utility accounts should stay active and in their name through possession (Redfin). If you set your account to start a week or two before closing, a few things can happen, none of them good:

  • You're paying for electricity, gas, or water usage in a home you don't own, sometimes usage the seller or their movers are generating.
  • Closings slip. Financing hiccups, title issues, a home inspection re-negotiation, a seller who needs an extra few days — any of these can push your closing date, and if your utility start date doesn't move with it, you can end up with two accounts open on the same address, or a service that starts before the seller's has stopped, which some providers won't even allow.
  • Some providers won't let two customers have active accounts on the same meter at the same time, which means an early request from you can actually force their account to close prematurely — the exact "seller loses utilities before moving out" problem this whole article is trying to help you avoid, just aimed at the wrong party.

There's no upside to jumping the gun. The house isn't yours to power up yet.

Why starting them too late is worse

The opposite failure mode is more dramatic: you close on a Tuesday, show up with a moving truck, and there's no power, no water, and no working outlets for the fridge you just bought. This happens more than you'd think, mostly because people assume utilities are like flipping a light switch — request it, get it same day — when in reality:

  • Electric and gas transfers are usually fast (often same-day to a few business days) but still require you to have already contacted the provider with the account number or service address, sometimes a credit check, and occasionally a deposit if your credit's thin or you're new to the area (Zillow).
  • Water is frequently a municipal account, not a private company — meaning you can't shop around, you're dealing with city or county government hours (weekdays, business hours only), and setup often requires you to show up (in person or via an online portal) with a government ID, proof of ownership or your closing documents, and a forwarding address, plus a possible $25–$50 setup fee or a $100–$150 deposit if they can't verify your credit right away. Some municipalities also route this through the title company at closing for the seller's final balance, but you still have to personally open the new account — that part doesn't happen automatically (Utilities For My Home).
  • Internet and cable are the real wildcard. If the home is already wired for the provider you want, you might get same-day to 48-hour turnaround. If not, cable installs commonly run 7–14 days out, and fiber installs can take 2–4 weeks, especially during peak moving season (May–September) when appointment slots — particularly evenings and weekends — book up fast (CompareInternet). If you want internet live on move-in day, you basically have to schedule it during that same 2–3-week pre-closing window, even though the electric/gas call can wait a little longer.

Translation: internet is the one utility where "start it the week of closing" can genuinely mean "no internet for two weeks," so it's the one to book first, not last.

How to actually do it, utility by utility

Electricity and gas. Find your local provider (search your address if you don't already know it, since it's not always the same company as your old place). Call or use their online "start service" form, and you'll typically need: the service address, your move-in/closing date, your name and contact info, sometimes a Social Security number for a credit check, and either the seller's old account number (if your agent or the seller can provide it) or just the property address. Set the requested start date to your closing date. Most providers can flip this on same-day or next-day once the request is in, which is exactly why this one doesn't need to be first in line (Zillow).

Water (and often sewer/trash, bundled together). Check whether your city or county runs this, which is true in most areas. Go to the municipal utility or public works website, or call directly — this is one of the few utilities you genuinely can't do entirely online in a lot of places. Bring or upload proof of ownership (your closing paperwork works once you have it, though you may need to start the request before that with just the purchase agreement), a government ID, and be ready for a setup fee and possibly a deposit. Because this runs on government business hours, don't try to set this up on the Friday afternoon before a Monday closing — give it real lead time within your 2–3 week window (Utilities For My Home).

Internet and cable. Search your new address on the provider's site to confirm what's actually available there (don't assume — infrastructure varies block to block), then book the earliest install slot near your closing date. If the home is already wired for that provider, ask specifically whether a technician visit is even required or if it's a self-install kit you can activate the day you get keys — that can save you the multi-week wait entirely. Do this step first among all four utilities, not last, given the lead times above (CompareInternet).

How this connects to your final walkthrough

Utilities need to be on — not just theoretically transferring, but actually flowing — when you do your final walkthrough, because that's your last real chance to test everything before you own the place and the seller stops answering their phone. You can't confirm the outlets work, the water heater actually heats, or the HVAC kicks on if the power and water are off. If you haven't read it yet, the site has a full separate piece on exactly what to check during that walkthrough and what your options are if something's broken — this article is about the utility timing that makes that walkthrough possible in the first place, not a repeat of that checklist.

Practically, this means the seller keeping utilities active through your walkthrough and through closing matters as much as you getting your own service started on time — which brings us to the other half of this.

The seller's side: don't cut it off too soon either

If you're the one selling (or you're buying and want to understand what the seller on your deal should be doing), the mirror-image mistake is disconnecting too early. Sellers should keep every utility active through closing and into the next business day, not stop it the moment they hand over keys (Redfin). The reasons line up with everything above:

  • The buyer's final walkthrough needs working utilities, full stop.
  • A vacant house with no power or heat, even for a day or two, risks frozen pipes in cold climates, mold from humidity with no HVAC running, and general property damage that can become the seller's problem if it happens before the deal legally closes.
  • Unpaid utility bills can turn into liens on the property, which is a genuinely bad way to have your closing delayed at the last minute over a $60 electric bill.

The clean move for a seller: schedule the disconnect/transfer-out request for the day after closing, not the day of and definitely not the day before. It costs a few extra dollars in overlap. It's cheap insurance against a canceled or delayed closing.

The one-line version

Call to set everything up 2–3 weeks before closing (internet first, since it has the longest lead time), but set electric, gas, and water to actually start on your closing date or the day before — never weeks early. If you're the seller, keep everything running through closing and cancel it the next business day. That's it — that's the whole trick, and almost nobody explains that "when to call" and "when to start" are two different dates until they've already messed one of them up.
