A natural-gas hookup can raise upfront cost, but steady fuel pricing often lowers long-run spending.
You’re staring at two grills that look similar. One runs on a propane tank. The other plugs into your home’s gas line. The natural next question is price: will the natural-gas model cost more, and will it stay more expensive once you start cooking?
The honest answer depends on where you spend your money. Natural gas grills can cost more at purchase, and the gas-line setup can add real dollars. Still, many owners end up paying less per cookout because they skip tank swaps and usually pay a lower fuel cost per unit of heat. This article breaks the decision into numbers you can check, plus the everyday stuff that changes what you’ll actually pay.
Are Natural Gas Grills More Expensive? In Real-World Budgets
Natural gas grills tend to run a bit higher at the same build level. Manufacturers add a natural-gas hose, fittings, and a regulator setup that’s meant for a fixed supply line. On top of that, a lot of the natural-gas models sit in “built-in” or higher-BTU lineups, which can bump the price tag.
But the grill price is only one slice. A propane grill often looks cheaper because the fuel system is “outsourced” to the tank you buy or exchange. With natural gas, the fuel system is part of your home. That shift is where the math changes.
Costs That Decide The Total Price
Most shoppers compare sticker prices and stop. A better way is to list every cost that can show up in the first year, then list the ongoing costs that repeat. Once you lay it out, you can see where natural gas can be pricier, and where it can pull ahead.
Upfront Costs You Pay Once
- The grill itself: model price, sales tax, delivery.
- Gas hookup: quick-disconnect kit, shutoff valve, and a line run if there isn’t one near your patio.
- Labor: a licensed pro may be required by local rules and insurance terms.
- Permits: some cities require a permit for new fuel-gas piping or for adding an outdoor outlet.
Ongoing Costs That Repeat
- Fuel: propane refills or exchanges versus natural gas billed through your utility meter.
- Parts that wear: igniters, hoses, and regulators wear out on both types. Replacement cost is usually similar.
- Storage and handling: propane tanks need safe storage and periodic requalification. Natural gas skips that step.
What Fuel Prices Mean For A Weekend Cook
Fuel cost is where natural gas gets its strongest advantage. A propane tank feels cheap because you pay in chunks, but propane is usually more expensive per unit of heat than natural gas. Your local utility rate still matters, and rates vary by region and season.
If you want to ground this in a public data source, the U.S. Energy Information Administration explains how natural gas prices are set and why they vary by location. That’s useful because a “cheap” natural-gas grill in one state may cost more to run in another.
How Much Gas A Grill Actually Uses
Grills are usually rated in BTUs per hour. That number is like a speedometer: it tells you the burn rate at full blast. Real cooking is rarely full blast for a full hour, but BTUs help you estimate.
- A medium grill might be rated around 30,000 to 40,000 BTU per hour.
- A larger grill with a side burner can land around 50,000 to 70,000 BTU per hour.
To estimate fuel, pick a realistic burn pattern. Many cooks preheat for 10–15 minutes, then turn down for the rest. If you average half-power for an hour-long session, a 40,000 BTU grill might use about 20,000 BTUs for that hour.
Where Propane Fees Sneak In
Propane cost is not just the fuel. Exchanges can include convenience pricing, and some swaps give you less than a full 20-pound fill. Refilling at a propane station is often cheaper than exchange cages, but it takes a trip and sometimes a wait.
Natural gas flips this: you pay for what you use, measured at your meter. No runs to the store. No wondering if the tank is half empty.
Setup And Safety Costs That People Miss
The gas line is the number-one reason natural gas grills can feel more expensive. If you already have an outdoor gas stub with a shutoff valve, the hookup can be simple. If you don’t, costs can jump fast because trenching, wall penetrations, and longer pipe runs add labor.
Fuel-gas piping needs to be done correctly. The National Fire Protection Association describes NFPA 54 as a standard with minimum safety requirements for fuel-gas piping design and installation. See the NFPA overview of NFPA 54 (National Fuel Gas Code) for what the code covers, then follow local requirements and professional advice for your area.
Typical Hookup Scenarios
- Existing outdoor outlet: usually the lowest setup cost. You may only need a hose and quick-disconnect fitting rated for outdoor use.
- Line near the wall: moderate cost. A pro can tap an existing interior line and add a shutoff and outlet.
- Long run to a patio or deck: higher cost. More pipe, more labor, and sometimes a permit and inspection.
What To Ask Before You Buy
Before you hit “add to cart,” check three things at your home:
- Distance: how far is the nearest gas line from where the grill will sit?
- Capacity: can your gas service handle one more appliance load?
- Routing: can the pipe run stay protected and out of foot traffic?
If any of these are unclear, a short site visit from a licensed plumber can save you from buying a grill that ends up parked in the garage.
Cost Breakdown By Category
The table below shows where the money usually goes. The ranges are broad on purpose because local labor rates and your yard layout can swing the number. Use it to build your own “best case” and “worst case” budget.
| Cost Area | Propane Grill | Natural Gas Grill |
|---|---|---|
| Grill purchase (mid-range) | $300–$900 | $350–$1,200 |
| Fuel setup at home | Tank deposit or purchase | Outdoor outlet, valve, quick-disconnect |
| First-year fuel spend | Varies with refill method | Varies with utility rate |
| Convenience costs | Trips for refills or exchanges | None for fuel supply |
| Unexpected “dead tank” moment | Common without a spare | Rare if the line is working |
| Seasonal storage | Tank storage rules apply | No tank storage |
| Resale and moving | Easy to take with you | May be harder if you move |
| Typical add-on cost | Spare tank, cover | Professional line run if needed |
When Natural Gas Costs More Over Time
Natural gas is not a win for everyone. There are cases where it stays more expensive, even after you cook on it for a year or two.
Short stays and rentals
If you expect to move soon, paying for a new line can be money you don’t recover. A propane grill comes with you. A fixed line outlet stays with the house.
High hookup cost for your layout
If the grill location is far from the meter, or the route needs trenching under hardscape, labor can dwarf the price difference between grills.
Low cooking frequency
If you grill once a month, fuel savings can’t offset a pricey hookup. In that case, the simpler setup can be the better buy.
When Natural Gas Can Save Money
If your home already has an outdoor gas outlet, the math shifts fast. The ongoing fuel price is usually lower, and the convenience is real. People grill more when they don’t have to plan around tank levels.
Frequent grilling and long cooks
Low-and-slow cooks, pizza stones, and long gatherings burn more fuel. When you cook for hours, the per-BTU price matters more than the sticker price.
Households that hate refills
If you’ve ever run out of propane mid-burger, you know the pain. Natural gas avoids that problem. You turn the knob and cook.
Built-in outdoor kitchens
If you’re already running a gas line for a built-in side burner or a fire feature, adding a grill outlet can be a smaller step than doing it later as a separate job.
Decision Table For Common Buyer Types
This table maps common situations to the option that usually fits best. It won’t replace a quote for a gas line, but it helps you spot your likely outcome before you spend.
| Your Situation | What Tends To Cost Less | Why |
|---|---|---|
| Outdoor gas outlet already exists | Natural gas | No major setup bill, then lower fuel cost per cook |
| You rent or expect to move soon | Propane | No money tied to a fixed line at one address |
| You grill 2–4 times a week | Natural gas | Fuel savings stack up across a full season |
| You grill once a month | Propane | Lower upfront spend wins when usage is low |
| Patio is far from the gas meter | Propane | Long pipe runs and trenching can raise setup cost |
| You want a built-in grill island | Natural gas | Many built-in units are sold as natural-gas ready |
Practical Ways To Cut The Total Cost
You can reduce the “natural gas costs more” risk with a few choices that don’t wreck the cooking experience.
Pick your grill tier first
Start by choosing the build level you actually want: size, burner count, and materials. Then compare propane and natural gas models inside that same tier. Comparing a bargain propane cart grill to a built-in natural gas unit will make natural gas look pricier than it is.
Get the hookup quote before you order
A line quote turns guesses into real numbers. Ask for the outlet location, shutoff valve details, and the type of quick-disconnect fitting. Get the parts list in writing.
Plan the grill location around the line
Even a small move can cut pipe length and labor. If you can place the grill closer to the wall line, you may save more than you’d get from a coupon.
Own your propane costs if you stick with tanks
If propane still fits you, buy a second tank and refill at a station rather than swapping. Two tanks reduce the odds of a dead cookout, and refills can beat exchange pricing.
What Most People End Up Paying
So, are natural gas grills more expensive? At the register, they often are. After setup, the story changes. If the hookup is simple or already in place, natural gas can be cheaper year after year. If the hookup is long and tricky, propane can win on total spend for a long time.
The clean way to decide is to get a hookup quote, estimate your grilling frequency, and compare both totals for the first year. Once you do that, the “mystery” disappears and you can buy with confidence.
