Missouri Cold Weather Rule: How to Stop a Winter Utility Shutoff (2026)
Revised July 13, 2026
What is the Missouri utility cold weather rule?
Missouri’s Cold Weather Rule blocks regulated electric and gas utilities from disconnecting your heat from November 1 to March 31 whenever the forecast predicts temperatures below 32°F within 72 hours. To stay protected, enter a payment agreement with your utility — and call before the disconnection date. It covers Ameren, Spire, Evergy, and Liberty.
Keep reading ↓It usually arrives on the coldest possible week. A shut-off notice with a date on it, and a pit in your stomach. Maybe you’re a grandmother in Overland who fell behind after a medical bill, or a family in Crystal City stretching one paycheck across two months of winter, or a worker in Washington whose hours got cut right when the furnace started running nonstop.
Here’s something Missouri utility companies don’t always volunteer: during the winter, they can’t just cut your heat off whenever they want. A state law called the Cold Weather Rule stands between you and a freezing house — but only if you know it exists and take the one step it requires. This guide explains exactly how it works, who it covers, and what to do the moment you’re worried about a disconnection, verified against Missouri’s current rule for the 2025–2026 winter.
Worried about a shut-off? Call your utility today and ask for a Cold Weather Rule payment agreement — before the disconnection date, not after.
What is the Missouri Cold Weather Rule?
The Cold Weather Rule is a Missouri regulation that limits when regulated electric and natural gas companies can disconnect your heat-related service during winter. It runs every year from November 1 through March 31. Its most important protection: a utility cannot shut off your service on any day the National Weather Service forecast predicts the temperature will drop below 32°F within the next 72 hours.
That 72-hour window is new. In 2025, Senate Bill 4 tripled it from the old 24-hour rule — so a single warm afternoon in the forecast no longer opens a window for disconnection. It’s a meaningful upgrade for families living paycheck to paycheck through a Missouri winter. The rule covers the service you use to heat your home — whether that’s natural gas or electricity — so both gas-heated and all-electric households are protected.
One thing the rule is not: it’s not free money and it’s not forgiveness. It delays disconnection and gives you a structured way to catch up — it doesn’t erase what you owe. Think of it as a legal timeout that keeps the heat on while you get back on your feet.
Which utilities does the Cold Weather Rule cover?
The rule applies to investor-owned electric and gas utilities regulated by the Missouri Public Service Commission (PSC). In the St. Louis area, that covers the big ones:
| Covered by the Cold Weather Rule | NOT covered |
|---|---|
| Ameren Missouri (electric & gas), Spire (gas), Evergy, Liberty — all investor-owned utilities under PSC jurisdiction | Municipal utilities (city-run), rural electric cooperatives, and propane delivered by truck — these are outside PSC jurisdiction |
If you’re served by a city utility, a co-op, or you heat with delivered propane, you’re not automatically covered — but don’t assume you’re out of luck. Many municipal utilities and co-ops adopt their own winter moratoriums voluntarily. Call your provider and ask directly what winter protections they offer.
What you must do to stay protected
The rule protects you, but it isn’t automatic — you have to act. To keep or restore service during the cold-weather months, you generally need to enter a Cold Weather Rule payment agreement with your utility. Here’s how it works:
- You agree to pay your current arrears spread over about 12 months, on top of your ongoing monthly bills.
- If you genuinely can’t afford that budget amount, you can ask for a longer term by mutual agreement — utilities are expected to work with you.
- Staying on the plan is what keeps the protection alive. Miss the agreed payments and you can lose it.
The single most important move is timing: call before the disconnection date. Once you’re on a payment agreement, the utility can’t disconnect you for the covered balance as long as you’re keeping up your end.
How to get reconnected if you’ve already been shut off
If your service is already off, the Cold Weather Rule still helps — you don’t have to pay the entire past-due balance to get the heat back on. Reconnection for less than the full amount owed is allowed under the rule.
The exact down payment depends on your history. If this is your first time needing help, entering a standard payment agreement is usually enough. If you previously defaulted on a Cold Weather Rule agreement, you’ll typically need to pay an initial amount — often 50% of the past-due balance or $500, whichever is less — and spread the rest over a new 12-month plan. Some utilities set higher down payments for repeat situations, so confirm the exact figure with Ameren, Spire, Evergy, or Liberty directly.
Once you make the required payment and enter the agreement, the utility must reconnect you promptly — and faster when temperatures are dangerous. One tip that saves people money: if you’ve applied for LIHEAP or a charity pledge, tell the utility. A pending pledge can count toward your reconnection and sometimes covers the down payment entirely, so ask whether it can be applied before you drain your own savings.
How to set up your payment agreement
When you call your utility, being specific and organized is the difference between a smooth agreement and a runaround:
- Say the words. Tell the representative you want to set up a Cold Weather Rule payment agreement. Naming it signals you know your rights.
- Know your numbers. Have your account number ready and a realistic sense of what you can pay each month on top of your regular bill.
- Get the terms in writing. Ask for the down payment, the monthly amount, and the length of the plan confirmed by email or mail.
- Don’t over-promise. Agree to a monthly amount you can actually sustain — defaulting on the plan is exactly what costs people their protection.
- Keep every confirmation number and receipt. If there’s ever a dispute, that paper trail is your proof.
The call itself is usually short. The hard part is making it before the disconnection date — so put it at the top of today’s list.
What happens when the rule ends on March 31?
This is the trap that catches people every spring: the Cold Weather Rule’s disconnection protection ends on March 31, and utilities can begin shutting off past-due accounts again starting April 1. If you rode out the winter on the rule’s protection but never got onto a payment plan, that first warm week is when the shut-off notices go out.
Don’t let winter’s breathing room lull you. Before the end of March, make sure you’re either caught up or locked into a payment agreement that carries you past April 1. If you’re on a Cold Weather Rule plan and keeping up with it, you stay protected — the plan doesn’t expire just because the season does.
Lower the bill so this doesn’t happen again
A payment plan handles this winter; free weatherization handles every winter after. If you qualify for LIHEAP, you likely also qualify for Missouri’s Weatherization Assistance Program, which pays for free insulation, air sealing, and furnace repair or replacement that permanently cut your heating costs. The same Community Action Agencies — CAASTLC in St. Louis County, the Urban League in the City — handle it, and it’s worth the wait list. Also ask your utility about Budget Billing, which averages your yearly usage into a flat monthly amount so a brutal January doesn’t blindside you.
Extra protection for serious illness
Missouri’s utility rules provide added protection when a disconnection would endanger someone’s health. If a member of your household has a serious illness, a licensed medical professional can certify that losing service would be especially dangerous, which can extend your protection. Ask your utility how to register a medical certification on your account, and have your doctor’s office ready to provide it. This lives in Missouri’s formal regulation (20 CSR 4240-13.055), so it’s a right, not a favor.
The Cold Weather Rule buys time — use it
The rule is a shield, not a solution. The smartest thing you can do with the breathing room it gives you is line up real help to pay down the balance:
- Apply for LIHEAP (Missouri Energy Assistance) — the state program that pays your utility directly, up to $800 for a winter crisis.
- Reach out to Heat Up St. Louis for charity grants toward past-due heating bills.
- Ask your utility about its own help — Ameren’s Keeping Current bill credits or Spire’s DollarHelp.
Use the timeout to stack these up. That’s how a winter emergency turns into a manageable plan instead of a shut-off in February.
If your utility won’t work with you
Utilities are required to follow the Cold Weather Rule. If you believe yours is violating it — refusing a payment agreement you’re entitled to, or threatening a disconnection during a cold-weather window — you have somewhere to turn. Contact the Missouri Public Service Commission Consumer Services line at 1-800-392-4211, or file a complaint at psc.mo.gov. You have rights as a utility customer, and the PSC exists to enforce them.

Frequently Asked Questions
How does the cold weather rule work?
From November 1 to March 31, Missouri’s Cold Weather Rule blocks regulated electric and gas utilities from disconnecting your heat when the forecast predicts temperatures below 32°F within 72 hours. To stay protected, you enter a payment agreement to spread your past-due balance over about 12 months while keeping up with current bills.
What temperature stops a utility shutoff in Missouri?
Under the 2025 update (Senate Bill 4), a regulated utility cannot disconnect heat-related service on any day the National Weather Service forecasts the temperature will fall below 32°F within the next 72 hours. That expanded window — up from 24 hours — gives Missouri families more protection during cold stretches.
Can my electricity be shut off in winter in Missouri?
It can, but not freely. During the November 1–March 31 Cold Weather Rule period, regulated utilities can’t disconnect when it’s forecast below 32°F within 72 hours, and they must offer you a payment agreement first. Municipal utilities, co-ops, and propane aren’t covered, so check your provider’s own winter policy.
How do I get my utilities turned back on after a shutoff?
Call your utility and ask for a Cold Weather Rule payment agreement. You don’t have to pay the full past-due balance — reconnection for less is allowed. First-timers usually just enter a 12-month plan; if you defaulted before, expect to pay 50% of the balance or $500 (whichever is less) down. Apply for LIHEAP at the same time.
Does the Cold Weather Rule cover Ameren and Spire?
Yes. Ameren Missouri, Spire, Evergy, and Liberty are all investor-owned utilities regulated by the Missouri Public Service Commission, so the Cold Weather Rule applies to them. It does not cover municipal (city-run) utilities, rural electric cooperatives, or truck-delivered propane, which fall outside PSC jurisdiction.
When does the Missouri Cold Weather Rule end?
The rule’s protection runs through March 31, and utilities can resume disconnecting past-due accounts on April 1. If you got through winter on the rule’s protection but never set up a payment plan, that’s when a shut-off notice can arrive. Get caught up or locked into a payment agreement before the end of March.
Does the Cold Weather Rule help renters?
Yes, as long as the utility account is in your name and you’re responsible for the bill, you’re protected the same as a homeowner. If your landlord holds the account and lets it fall behind, that’s a different situation — call the Missouri PSC at 1-800-392-4211 for guidance, and dial 2-1-1 for tenant and emergency housing resources.
