Lower Utility Bills Without the Thermostat: 12 Fixes
Quick answer: Focus on what uses energy besides heating and cooling: your water heater, leaks, lights, appliances and your rate plan. Set the water heater to 120°F, fix running toilets, wash in cold water, and call your utility about free audits, budget billing and assistance programs.↗ Share on X
You can cut your monthly utility bills without touching the thermostat by going after everything else that uses energy and water in your home. The biggest targets are usually your water heater, hidden leaks, lights and appliances, and your rate plan. Many of these fixes cost little or nothing and take less than an hour. Below are 12 of them, grouped from easiest to more involved, plus how to check whether they are working.
A quick note: every home is different, and your savings depend on your local rates, your equipment and how you use it. This article gives practical steps, not a promise of a specific dollar amount. If you are behind on payments or facing a shutoff, call your utility right away and ask about help. Do not wait.
Where does the money on a utility bill actually go?

| Area | Examples | Why it matters |
|---|---|---|
| Water heating | Showers, laundry, dishwasher | Runs every day, all year |
| Appliances | Fridge, dryer, oven, freezer | Some run 24 hours a day |
| Electronics | TVs, consoles, chargers, routers | Many draw power on standby |
| Lighting | Ceiling lights, lamps, outdoor lights | Adds up across many bulbs |
| Water use | Toilets, faucets, outdoor watering | Leaks waste water around the clock |
| Your rate plan | Fixed, tiered, time-of-use | The same usage can cost different amounts |
Start with the areas that run all the time. Those are where small fixes add up month after month.

1. Lower the water heater to 120°F
Many water heaters come set higher than most homes need. The U.S. Department of Energy suggests 120°F for most households. Look for the dial on the tank. On gas models it is near the bottom. On electric models it may be behind a small panel, so turn off the power at the breaker before opening it. If anyone in your home has a weak immune system, ask a doctor before lowering it.
2. Wash clothes in cold water
Most of the energy a washing machine uses goes to heating water. Modern detergents clean well in cold water for everyday loads. Save hot water for very dirty items, towels or bedding when needed.
3. Clean the dryer lint screen every load
A clogged screen makes the dryer run longer. Clean it every time. Once or twice a year, also check the vent hose outside for lint buildup. That also lowers fire risk.
4. Find and stop standby power
Game consoles, cable boxes, printers, old chargers and TVs can draw power even when "off." Walk through your home and unplug devices you rarely use. For a cluster like a TV setup, a smart power strip can cut power to several devices at once.
5. Swap the bulbs you use most for LEDs
You do not need to replace every bulb at once. Start with the five or six lights that stay on the longest, like the kitchen, living room and porch. LED bulbs use much less electricity than old incandescent bulbs and last far longer.

6. Do the toilet dye test
1. Remove the lid from the toilet tank.
2. Add a few drops of food coloring to the tank water.
3. Wait 15 to 20 minutes without flushing.
4. If color shows up in the bowl, the flapper is leaking.
A new flapper is cheap at any hardware store and usually takes a few minutes to replace.
7. Read your water meter at night
1. Turn off every faucet, appliance and sprinkler.
2. Write down the meter reading before bed.
3. Check it again in the morning before anyone uses water.
4. If the number changed, you likely have a leak somewhere.
If the leak is hard to find, call your water utility. Some will help check for leaks.
8. Install a low-flow showerhead
Federal rules cap showerheads at 2.5 gallons per minute. Models with the EPA WaterSense label use 2.0 gallons per minute or less. Because less hot water flows, this cuts both your water and your water heating costs. Many screw on by hand.
Can my rate plan really change my bill?
Yes. The same amount of energy can cost different amounts depending on your plan. This is often the most overlooked fix.
9. Ask your utility about rate options
Call the number on your bill and ask:
- "What rate plans do you offer for my home?"
- "Is there a time-of-use plan?" That means electricity costs less at certain hours, often late at night. If you can run the dishwasher and laundry at those times, it may help.
- "Am I on the best plan for my usage?"
Be careful: time-of-use plans can cost more if you use a lot of power during peak hours. Ask for a comparison using your past 12 months of usage before you switch.
10. Check your bill for errors
Look for:
- An estimated reading instead of an actual one. If the estimate is high, ask for a real reading.
- Charges you do not recognize, like extra services.
- A meter number that does not match the one on your home.
If something looks wrong, call and ask. Billing mistakes happen.
11. Compare suppliers if your state allows it
In some states you can choose who supplies your electricity or gas, while your local utility still delivers it. Read offers carefully. Watch for teaser rates that jump after a few months, cancellation fees and automatic renewals. If you do not understand a contract, do not sign it.
What free help is available?
12. Get a free or low-cost energy audit and ask about programs
Many utilities offer free home energy checkups, rebates on efficient appliances, or free items like LED bulbs and weatherstripping. Ask your utility:
- "Do you offer a free home energy audit?"
- "Do you have rebates or free efficiency kits?"
- "Do you offer budget billing?" This spreads your yearly costs into similar monthly payments. You pay about the same total, but there are fewer surprise bills.
- "What payment plans or hardship programs do you have?"
If money is tight, ask about LIHEAP, the Low Income Home Energy Assistance Program. It is a federal program run through states that helps eligible households with energy bills. Some states also offer weatherization help for free. You can call your state or local energy assistance office to see if you qualify.
How do I know if these fixes are working?
Do not guess. Track it.
1. Pull your last 12 bills. Most utilities show them online. Write down the usage, not just the dollar amount. Electricity is shown in kilowatt-hours (kWh), gas in therms or CCF, and water in gallons or cubic feet.
2. Compare the same month from last year. Weather changes usage, so January should be compared with last January, not with June.
3. Make a few changes at a time. That way you can see what made a difference.
4. Check again in two or three months. If usage dropped, keep going. If not, move to the next fix on the list.
What should I avoid?
- "Energy saving boxes" sold online that plug into the wall and promise to cut your bill. Be very skeptical of these.
- Door-to-door sellers who ask to see your bill and push you to sign right away. Never share your account number with someone you did not call.
- Big purchases before small fixes. A new fridge may help eventually, but a leaking toilet and a hot water heater set too high cost you every single day.
Your next step
Tonight, do two things that take less than 30 minutes: check your water heater setting and do the toilet dye test on every toilet. Tomorrow, call your utility and ask three questions: whether they offer a free energy audit, whether there is a better rate plan for your usage, and what assistance programs exist. Write the answers down and add them to your monthly budget so you can see the difference on the next bill.
FAQ
What is the fastest way to lower my electric bill this month?
Check your water heater setting, unplug devices you rarely use, wash clothes in cold water, and call your utility to ask about a cheaper rate plan or a payment program. These take a day or less.
Does unplugging appliances really save money?
It can help with devices that stay on standby, like game consoles, cable boxes and old chargers. The savings vary by device. A smart power strip makes it easy to cut several at once.
Is budget billing a way to pay less?
No. Budget billing spreads your yearly cost into similar monthly payments. You pay about the same total, but it avoids big surprise bills in summer or winter, which helps with planning.
Where can I get help paying a utility bill that is past due?
Call your utility first and ask about payment plans and hardship programs. You can also ask about LIHEAP, a federal program that helps eligible households with energy bills, through your state or local agency.
