Propane contracts often look identical until you actually need service—then hidden fees, minimum purchase requirements, and automatic renewal clauses bite you. Before signing, you need to know what you're committing to, what it costs, and what happens if you want out. This guide walks you through the key terms and red flags every propane customer should spot.
Price Terms and Rate Structures
Your propane contract will specify pricing in one of three ways: fixed-rate, variable-rate, or tiered pricing. A fixed-rate locks your price per gallon for a set period (often one heating season), so you're protected if market rates spike. Variable-rate contracts adjust monthly based on wholesale costs, meaning your bill swings with market conditions—typically ranging from $2.50 to $4.50 per gallon depending on region and season.
Check whether pricing includes delivery fees. Many contracts bundle a flat delivery charge ($50–$150 per delivery) or a per-gallon rate. Others charge separately for each fill-up, which adds up fast if you need frequent small deliveries. Always ask your propane supplier to break down the total cost per gallon including all fees.
Minimum Purchase and Delivery Obligations
This is where customers often get surprised. Many contracts require a minimum annual purchase (typically 500–1,000 gallons per year) or a minimum per-delivery amount (often 100 gallons). If you don't use that volume, you may pay a penalty or true-up fee at contract end.
Similarly, some agreements lock in a minimum number of deliveries per year. If you're on a shared delivery route and your supplier services your area only once monthly, you could face charges if you schedule fewer stops. Read the fine print on what happens if you fall short.
Auto-Delivery and Tank Ownership
Most propane companies offer automatic delivery, where they monitor your tank and refill it before it empties. This prevents outages but also means ongoing charges. Confirm:
- Does the supplier own your tank, or do you?
- Who pays for tank maintenance and inspections?
- Can you switch suppliers while they own the tank?
If the company owns the tank, you may be locked into their service unless you buy out the tank (usually $300–$800) or wait until the contract ends. Owned tanks give you freedom to shop around.
Contract Duration and Early Termination
Standard propane contracts run one to three years. Before signing, look for:
- Early termination clauses – What's the penalty if you need to stop service early? Typical early exit fees range from $150 to $500 plus any outstanding balance.
- Renewal language – Does the contract auto-renew unless you give notice? Some require 30–60 days' written notice before expiration, or you're locked in another year.
- Price lock duration – How long is your rate guaranteed? A year? Just winter? Knowing when rates reset helps you plan.
Automatic Renewal and Cancellation
This is the biggest gotcha. Most propane contracts auto-renew silently at the anniversary date. You miss the deadline, and suddenly you're locked in for another year—often at a new, higher rate that wasn't shown upfront.
Add a calendar reminder 90 days before contract end. Call your supplier in writing (email counts, but certified mail is safer) to confirm you're canceling or renegotiating. Ask exactly what notice period they require.
Service Level and Delivery Guarantees
Check what happens if the supplier fails to deliver. Does the contract guarantee 24/7 emergency service during winter? Is there a service level agreement (SLA) with response times? Some contracts waive their obligation during extreme weather, so you're on your own during the coldest days—exactly when you need propane most.
Comparing Terms Across Suppliers
Don't just compare price per gallon. Create a side-by-side table listing:
- Price per gallon (all-in)
- Minimum annual purchase
- Delivery fees and frequency
- Tank ownership
- Cancellation penalty
- Auto-renewal notice period
- Rate lock duration

Frequently Asked Questions
Q: Can I lock in a fixed rate for multiple years? Yes, some suppliers offer 2–3 year fixed rates, but the per-gallon price is usually higher than a 1-year rate to offset their risk. Compare the total cost over the contract life, not just the rate.
Q: What if I move or no longer need propane before my contract ends? You'll likely owe an early termination fee ($150–$500) plus any remaining balance, unless the company serves your new location and allows contract transfer. Always ask about relocation terms before signing.
Q: Are there contracts with no minimum purchase requirements? Some smaller regional suppliers offer flexible, month-to-month agreements with no minimums, but expect to pay a higher per-gallon rate to offset their risk. It's a fair trade-off if you value flexibility.
