FUEL-1 (Fuel Tank Adjustment Acknowledgement) does one thing: it records that the parties agree there will be no adjustment on completion for unmetered fuel. It exists because the standard agreement otherwise contemplates apportioning items like taxes, utilities and fuel to the completion date, and unmetered fuel — oil in a basement tank, propane in a yard tank, a delivery of pellets — cannot be read off a meter the way hydro and natural gas can. Whether the clause helps your client depends entirely on how full the tank will be on closing day, which nobody knows when the offer is drafted. That is the whole problem.
The 3 p.m. email about a half-full tank
Closing day, mid-afternoon. The buyer’s lawyer emails the seller’s lawyer asking for the fuel adjustment. The seller’s lawyer has no invoice, no reading and no instruction. Somebody phones the listing agent, who phones the seller, who says the tank was filled in November and they are certainly not handing over several hundred litres of oil for free. Nobody wrote anything about fuel in the agreement, the funds are already ordered, and two lawyers now have to settle a few hundred dollars before the registration window closes.
That is the fuel tank argument. It is small money and it is the most reliably irritating item on a rural or oil-heated file, because it arrives at the worst possible hour and both clients feel cheated. FUEL-1 exists to end the argument in advance by agreeing there will be no adjustment at all. Used thoughtfully, it is a good clause. Used as a default, it is a quiet transfer of value from one of your clients to the other.
Unmetered fuel is not the same as a utility
Hydro and natural gas are metered. The utility reads the meter, bills to the date, and the adjustment either happens automatically or is handled cleanly between lawyers. Nobody argues about a meter reading.
Unmetered fuel is different because the commodity is already on the property and already paid for. Furnace oil sits in a tank in the basement or beside the house. Propane sits in a leased tank in the yard. Wood and pellets sit in a shed. The seller bought that fuel with their own money. If the transaction closes and nothing is said, the buyer takes possession of fuel they did not pay for, or the seller takes a credit for fuel nobody has measured. Either way somebody is going to feel the difference, and the amount is large enough to be worth an argument and small enough that no one wants to pay a lawyer to have it.
The short version
Metered means the utility settles it. Unmetered means you and the other agent settle it, at the front of the deal or on closing day. There is no third option where it takes care of itself.
What FUEL-1 actually decides, and who it favours
FUEL-1 is an acknowledgement, not a condition. Nobody investigates anything and nobody gets a way out. The parties simply agree that unmetered fuel will not be adjusted on completion. Pull the exact wording from your own OREA member copy — it is one of the shortest clauses in the book and it is worth reading in full before you use it, because the scope of the words matters more than the length suggests.
The side it favours is decided by the tank level on closing day, which is precisely the fact nobody knows when the offer is signed. A full tank at closing means FUEL-1 is a gift to the buyer. A near-empty tank means it is a gift to the seller, who avoids both the argument and any expectation that they will top it up.
Think about the calendar. An offer signed in October for a January closing on an oil-heated rural property is being signed at the point in the year when sellers fill tanks. An offer signed in March for a May closing is being signed at the point in the year when tanks run low. Same clause, opposite consequence. I have watched a buyer’s agent insert FUEL-1 in June to look efficient and hand their own buyer a bill in a year when the seller was on a budget plan and let the tank run down before closing.
| Fuel or energy source | Metered? | How it usually gets settled | What to put in the agreement |
|---|---|---|---|
| Natural gas | Yes | Utility bills to the reading date; lawyers handle any residue | Nothing special |
| Electricity | Yes | Utility bills to the reading date | Nothing special |
| Furnace oil | No | Either no adjustment (FUEL-1) or a fill and invoice before completion | Decide deliberately, and say which |
| Propane in a leased tank | No | Supplier account transfer, plus whatever the parties agree about the fuel in the tank | FUEL-1 or a measured adjustment, plus the rental contract in CHATT-8 / CHATT-9 |
| Propane in an owned tank | No | Tank is a fixture question; fuel is an adjustment question | Deal with tank ownership separately from fuel |
| Wood, pellets, coal | No | Almost always left alone unless the seller raises it | FUEL-1 covers the argument if you want it closed |
| Prepaid or budget-plan supplier accounts | No | Credits sit with the supplier, not with the property | Ask the seller for the account status before drafting |
Why the argument is predictable: nobody can prove the number
Even when the parties agree in principle to adjust, the adjustment is hard to compute, and that is the real reason FUEL-1 exists.
- Measurement is approximate. A float gauge on an oil tank and a percentage dial on a propane tank are indicators, not instruments. Two people reading the same gauge on the same afternoon will not agree to the litre.
- Price is contested. The seller’s last invoice reflects the price on the day of that delivery, not the price on closing day, and fuel pricing moves. Whose number governs is a negotiation nobody had.
- Ownership of the tank and ownership of the fuel are different questions. A leased propane tank belongs to the supplier; the propane in it may or may not, depending on the contract.
- Timing is awkward. A pre-closing fill gives you an invoice and a known quantity, but it also means the seller spends money on a house they are leaving, which is a conversation to have before they agree to it.
None of this is legally complicated. It is operationally annoying, and operationally annoying is what produces closing-day emails between lawyers who are billing for their time.
The tank is worth far more than the fuel in it
Here is where the fuel tank file stops being small. The fuel is worth a few hundred dollars. The tank, and the ground under it, can be worth six figures if it has leaked, and that is the exposure that ends careers rather than closings.
OREA’s environmental clauses carry the real machinery. ENV-5 (Condition – Oil Tank – Aboveground or Underground) makes the deal conditional on the buyer obtaining, at their expense, a report from a fuel oil distributor registered under the Technical Standards and Safety Act confirming the tank system is in safe operating condition and complies with that legislation, with the seller agreeing to give the distributor access. ENV-12 (Underground Tank – Compliance Warranty) is the seller-warranty version, including provision of the registration number and documents before closing. ENV-13 covers a tank the seller has already removed, with evidence of removal, soil assessment and remediation from a registered contractor. ENV-14 is the version where the seller agrees to do that removal, assessment and restoration before closing, at their expense.
If you are writing FUEL-1 on an oil-heated property and you have not asked whether there is or ever was an underground tank, you have spent your attention on the cheapest item in the file. Whether a particular tank meets the applicable fuels safety requirements is a question for a registered distributor or contractor, not for you and not for the seller’s memory. And insurers commonly decline, surcharge or restrict coverage on older oil tank installations — that is industry practice as I see it on files, not a regulatory statement, and your buyer should be talking to their broker during the condition period rather than the week before closing. More on the whole family of these in my post on environmental clauses.
Propane brings a different problem: the tank is usually leased. CHATT-8 (Rental Items) and the CHATT-9 rental checklist, which lists a propane tank among the items to be identified, are where that belongs — the rental contract has to be identified, and its assumability confirmed, or your buyer inherits a supply agreement nobody read. See chattels and fixtures for how those clauses interact.
The short version
Ask the fuel question and the tank question in the same breath. Is it oil or propane, is the tank above or below ground, who owns it, was there ever another one, and is the supplier account transferable? The adjustment is the least important answer on that list.
Your exposure as the registrant who wrote it
The money is small, so agents assume the exposure is small. It is not, for two reasons.
The first is that a clause you inserted without instruction is a clause you chose. If you put FUEL-1 into an offer for your seller in November on a house with a freshly filled tank, you gave away your own client’s property without asking them. That is not a legal opinion, it is a service failure, and it is documented on the face of the agreement in a clause your client did not request. Ask, then draft, then note that you asked.
The second is the disclosure framework sitting underneath the tank. Patent defects are caveat emptor and actively concealing one removes that protection; latent defects that render a property unfit or dangerous must be disclosed, and where a seller’s agent knows of such a fact they must disclose it to every interested buyer, use best efforts to obtain an acknowledgement from each, and give each a copy. Those duties come from case law rather than the regulations under TRESA. Whether a decommissioned tank or a past spill falls into that category is a legal characterisation and belongs to the client’s lawyer — but “the seller mentioned there used to be a tank in the side yard” is information you cannot unhear, and burying it in an acknowledgement about fuel adjustments is not disclosure.
One more, for completeness. If the other side is self-represented, you do not get to advise them on whether to accept FUEL-1. Confirm they intend to proceed unrepresented, deliver and explain the RECO Information Guide and the Information and Disclosure to Self-Represented Party form, state plainly that you act for your client, and make reasonable efforts to get written acknowledgement of that form. Telling an unrepresented seller that a no-adjustment clause is standard and harmless is advice on terms, and it is not yours to give.
How I handle fuel on an oil or propane file
- At the listing appointment, ask what heats the house, where the tank is, who owns it, and whether there was ever an underground tank. Record the answers.
- Get the supplier’s name and the account status. Prepaid credits, budget plans and lease-to-own tanks all change the conversation.
- Decide with the client, in advance, whether they want no adjustment or a measured one — and put the season and the closing date in front of them while they decide.
- If the buyer wants any comfort about the tank itself, that is ENV-5 with a realistic condition period, not a line about adjustments.
- If the parties want an adjustment, have it handled through the lawyers with a supplier document. The shape of the instruction is: seller arranges a fill or a supplier reading immediately before completion, the invoice or reading goes to both lawyers, and the value is carried into the statement of adjustments. Illustrative only, and my own description rather than OREA’s — have the lawyer draft the actual term.
- Confirm the supplier account transfer and, in heating season, a delivery date before the buyer takes possession.
- Write the client’s instruction in your file notes the day you receive it.
Ten minutes at the listing appointment. It removes the 3 p.m. email entirely, and more usefully, it is the conversation in which you find out there is a 1970s tank buried beside the garage.
Questions agents actually ask
What does FUEL-1 actually do?
It records the parties’ agreement that there will be no adjustment on completion for unmetered fuel — the oil, propane, wood or pellets already sitting on the property. It is an acknowledgement rather than a condition, so nobody investigates anything and nobody gains a way out of the deal. It settles the money question in advance instead of leaving it to the lawyers on closing day.
Does a fuel adjustment happen automatically if I say nothing?
Not cleanly. The standard agreement contemplates apportioning items to the completion date, which is why a clause exists to opt out, but unmetered fuel cannot be read off a meter. In practice, silence means the lawyers negotiate it on closing day with no measurement and no agreed price. That is the argument FUEL-1 is designed to prevent.
Who does a no-adjustment clause benefit?
Whichever side happens to be lucky on closing day. A full tank at completion means the buyer receives fuel they did not pay for. A near-empty tank means the seller avoids both the argument and any expectation of topping it up. Because the tank level is unknown when the offer is drafted, the season and the closing date are the best guide you have.
How do you adjust for oil or propane if you do not use FUEL-1?
Through a document rather than an estimate. The usual approach is for the seller to arrange a fill or a supplier reading immediately before completion, deliver the invoice or reading to both lawyers, and have the value carried into the statement of adjustments. Agree the mechanism before acceptance, and have the lawyer draft the term — gauge readings alone invite a dispute.
Is the fuel tank clause the same as an oil tank condition?
No, and the difference matters. FUEL-1 is about money for the fuel. ENV-5 is a buyer condition for a report from a registered fuel oil distributor about whether the tank system is safe and compliant, and ENV-12 through ENV-14 deal with warranties, removal, soil assessment and remediation. The fuel is worth a few hundred dollars; the tank can be worth vastly more.
What about a leased propane tank?
Treat the tank and the fuel as two separate items. A leased tank belongs to the supplier and the rental or lease-to-own contract has to be identified and its assumability confirmed, which is what CHATT-8 and the CHATT-9 rental checklist are for. Confirm with the supplier whether the account can be transferred and whether any charge applies before you promise your buyer anything.

Who reviews the small clauses on your rural files?
The fuel adjustment is the cheapest item on an oil-heated file and the one that starts the closing-day phone call. At my brokerage the small clauses get read too, because they are usually attached to a much larger question about the tank. If nobody is reading yours, let us talk.

This is professional commentary from a Broker of Record on Ontario drafting practice around fuel adjustments and fuel storage tanks, not legal advice. Whether a particular tank or past spill creates a disclosure obligation, and how any adjustment should be documented, are questions for the client’s lawyer and a registered contractor.
