How do renter referrals work?
Karshare will reward users when they invite others to join the platform. You can earn rewards by sending your personal referral link to friends and family who are looking to rent with Karshare.
Once they’ve completed their rental we’ll add 20 Karshare Credits (worth £20) to your account OR we’ll add £20 to your owner balance if you have a car on the Karshare platform. You’ll receive your £20 reward once your friend has successfully completed their first rental.
Please note that if you have a car on the platform, the £20 added to your owner balance will (or may) be used to help pay off any outstanding negative balance. If you don’t have a negative balance, we’ll send the £20 reward straight to your chosen payout method.

What are Karshare Credits?
Karshare Credits can be used to receive discounts on rental bookings. They’re applied automatically at the checkout and will reduce the total rental cost. Each Karshare Credit is worth £1 in discounts, so if you have 20 Karshare Credits, you’ll receive £20 off your next rental.
Renters can earn Karshare Credits by inviting friends and family to use Karshare through our referral scheme.Learn more
How many Karshare Credits can I earn?
There is no limit to the amount of Karshare Credits you can earn through renting cars with us and referring friends. If you have accumulated £50 in Credits, and your next booking is worth £50, you will get that booking for free.
There is, however, an expiry date on Credits. Unused Karshare Credits will expire after 12 months from the date you earned the Credit. You can keep an eye on your Karshare Credits in your account information.
What happens if my booking is cancelled?
We treat our Karshare Credits just like regular money. If your booking is cancelled by the car owner and you made the booking using Credits, we’ll return them to your account with the original expiry date.
If you cancel your rental booking, you will receive a full, partial or no refund in Karshare Credits, according to our cancellation policy.
