Short answer:

If you need to fill up during a trip, pay for fuel yourself and ask for a tax invoice. Upload a clear photo of the receipt through the app. This amount will be credited towards the final cost of your trip and any extra refunded.


You must return the car with at least 1/4 of a tank of fuel. If it is left with less, there is a fee applicable (see Inconvenience and admin fees.)

Getting fuel instructions

Make sure you check what type of fuel the car takes before filling up. You'll find this information in your trip instructions in the app during your trip.

  1. Open the app and go to Trips
  2. Select your in progress trip
  3. Tap 'Refuel'
  4. Read the instructions to see what kind of fuel the car takes
  5. Fill up and pay using your own money
  6. Ask for a tax invoice - make sure it details:
  • type of fuel purchased
  • how many litres you purchased
  • how much you paid in total
  • time and date of purchase

Submitting a receipt for reimbursement

  1. Tap 'Refuel' in the app
  2. Tap 'Add receipt'
  3. Tap 'Add photo' to take or upload a photo of the tax invoice - make sure the entire invoice is clear and readable in the photo
  4. Enter the total cost of the fuel and the number of litres purchased - you can see this information on the tax invoice
  5. Tap 'Upload receipt'

You can also upload the receipt after your trip through the app or website.

We'll credit the amount you spent on fuel towards the final cost for this trip. If you spent more on fuel than the final trip cost, we'll refund the balance to your Car Next Door account. It will then be refunded to your card within a few days, or you can withdraw it back to your credit or debit card anytime.

Always check if the car takes petrol or diesel before filling up!

Make sure you check the kind of fuel the owner has specified should go into the car. If the car takes unleaded petrol, the instructions will also specify whether you should use 91 (regular), or 95 or 98 (premium).

 Put the wrong fuel in the car?

If you've put petrol in a diesel car or vice-versa, don't start the car. If you already have, stop driving and switch off the engine ASAP. Read these instructions for what to do next.

  • In my opinion, this is a terrible initiative. One of the key reasons of me using CND was the ease and availability of the fuel cards & that it is already paid for in the kms run by the vehicle. Now that, fuel has to be paid upfront and a receipt uploaded & having to wait for the money to get refunded, is an addition of an extra layer & in my opinion just making the whole process a lot longer!

  • I agree with @Mishel. This is a terrible idea and probably the only reasons I will not be using Car Next Door anymore. If I spent more on fuel I would not want this in my CND account either, I would want my outstanding money back not locked into CND.

  • Also, having gone through this process before because a fuel card was not working I know how tedious this is. Bad idea.

  • We've improved the fuel refund process to make it quick and easy to upload a photo of your receipt in the app, and quicker for our team to review and approve refunds. You won't be out of pocket because the amount you spend on fuel will be deducted from your distance cost before we charge you. If the fuel costs more than your trip, you can withdraw the extra back to your card - you don't have to leave it in your Car Next Door account. If you're keeping track of how far you've driven, you can also choose to only fill up with as much as you think your trip will cost so there isn't any extra for us to refund to you.

  • The new fuel system works well for me. I think it's a good initiative. Don't have to fill up every time either, just sometimes and just small amounts. Worth the small inconvenience in my opinion. You're getting someone elses car, there's gotta be some processes involved. Keep up the good work CND.
