Europcar prices missing fuel at 2.5 times the pump

What does Europcar charge if you return the car not full?

Europcar UK charges you for every litre needed to refill the tank, and prices each litre at the pump price multiplied by 2.5. The formula sits in two live documents read on 17 September 2026, the UK Tariff Guide updated 1 June 2026 (reference 453B1-24-06-26) and the fuel question on the UK FAQ, which writes it out as Missing Fuel Cost = (Pump price per litre x 2.5) x Number of litres required to refill. Both add that an estimate of the price factor is printed on your rental agreement.

There is no separate refuelling fee on top in the current Tariff Guide. The multiplier is the fee. That matters because most pages about hire car fuel say the company charges above pump price and stop there. Europcar publishes the number, so the arithmetic can be done before you skip the petrol station on the way back.

The rule applies to the standard full to full option, where the car is handed over full and you agree to bring it back full. If you bought the Full Tank Option at pick-up, a different rule applies, covered further down.

How much is that in pounds?

Europcar does not publish which pump price it uses, and the estimate on the rental agreement is the figure that will actually be billed. As a stand-in, the UK government's weekly road fuel price series gives a national average of 168.14p per litre for petrol and 190.72p for diesel in the week beginning 14 September 2026. Multiply by 2.5 and a missing litre of petrol is priced at about £4.20, a litre of diesel at about £4.77.

The table works through a 50-litre petrol tank at that price. The pump column is what the same fuel costs you at a forecourt, the last column is what Europcar bills for it.

Why the gap is the point

Half a tank you could have bought for about £42 costs about £105 if Europcar refills it, a difference of roughly £63 for skipping one stop. Diesel is worse, the same 25 litres comes to about £119 against about £48 at the pump. Tank sizes vary, so scale the table to the car. The multiplier does not change.

The FAQ also explains how the litres are counted, and it depends on whether you are there. If you are present at check-in, staff read the gauge and convert the reading to litres using the tank capacity. If you are not present, Europcar refills the car and charges the exact number of litres the pump takes. Either way those litres are then priced at 2.5 times the pump price.

The older UK terms of hire, a PDF dated 8 July 2019 still served on europcar.co.uk on 17 September 2026, describe rounding to the nearest eighth of a tank, with a needle exactly halfway rounded in your favour, and say a car returned at seven eighths or more is not charged. The current FAQ does not repeat the eighths rule, so treat it as history rather than a promise. Returning in person still matters, because an absent return is charged on whatever the pump says, with no rounding.

What did the old terms say, and which version applies?

Europcar's UK documents disagree with each other. The PDF terms of hire dated 8 July 2019, still live on 17 September 2026, price missing fuel at 30p per litre above the cost of each litre, add a one-off refuelling surcharge of £18 when more than seven litres are missing, and waive the surcharge at seven litres or less. The Tariff Guide updated 1 June 2026 replaces all of that with the flat 2.5 multiplier and mentions neither a seven-litre threshold nor an £18 fee. The seven-litre rule gets its own post, seven litres before the fuel surcharge.

• Which rule binds you is written on the rental agreement you sign at the desk. The Tariff Guide says the estimated fuel charge is printed there, and the FAQ says the same.
• Read that line before you sign and photograph it. If the number does not match what you were quoted, ask at the counter, not after the invoice arrives.
• The 2019 PDF priced the Full Tank Option at 6p or 12p per litre below Europcar's average fuel price, depending on where the rental starts. The 2026 Tariff Guide says the option is priced at the average fuel price and mentions no discount.

Is the Full Tank Option cheaper than being charged?

The Full Tank Option is a pre-authorisation for a full tank taken at pick-up. Return the car full and the pre-authorisation is not processed. Return it anything short of full and Europcar processes the whole tank, regardless of the fuel gauge level, in the FAQ's own words. So it is a bet that you will bring the car back close to empty.

At the 2026 Tariff Guide price the option costs roughly what the fuel costs at the pump, about £84 for a 50-litre tank of petrol at 168.14p. Bring the car back a quarter full and you have paid for 12.5 litres you did not use, about £21. Bring it back half full and the wasted fuel is about £42. Set that against the 2.5 times charge, where half a tank missing costs about £105, and the option wins whenever you would otherwise return the car with more than a few litres missing and cannot stop at a pump.

The cheapest outcome is still the boring one. Fill up within a few miles of the branch, keep the receipt, and pay the pump price once. Under the 2019 terms a receipt from a station within 15 miles of the branch and 24 hours of return was the accepted proof of a full tank on rentals of 60 miles or less, and a receipt still settles arguments about a needle a width under full. Refuelling charges are a contract term you agreed to, not an insured loss, so they do not appear among the things a policy pays in the guide to what travel insurance covers.

What to do before you hand the keys back

Five checks, in the order they come up.

• Find the estimated fuel charge line on the rental agreement at pick-up and photograph it. That number, not the FAQ, is what will be billed.
• Check the gauge reads full when you collect the car. The 2019 terms tell you to do this before signing, and a car handed over at seven eighths is your problem at return if you did not note it.
• Fill up as close to the branch as you can and keep the receipt with the time and address on it.
• Return in person if you can. Absent returns are charged on the litres the pump takes, with no gauge reading and no discussion.
• If the invoice shows a fuel charge you dispute, ask for the litres and the price per litre used. The formula has only two inputs, so the challenge is short.

What else can the desk add?

Fuel is one of several lines a hire desk can add. Tolls, extra drivers, congestion charges and deposits each have published figures, read the same way in Hertz's toll fee, the additional driver fee cap, the London congestion charge on a hire car and Portugal's 3,000 euro hire car deposit. If the car was only ever for the airport run, the airport transfers versus taxi guide compares the fixed-price alternatives with no tank to fill.

Every figure on this page was read from the named document on the date shown, and the pump price is the government's weekly average for that week, not a forecast. The methodology sets out how figures are read and rechecked.
