Open the booking, click the cancel button at the bottom of the drawer and choose a refund for each player. Full refund is pre-selected for every player who can be refunded, so check each player's choice before you confirm.
Steps
Go to Calendar → Schedule and click the booking.
Click the cancel button at the bottom of the drawer. It's named after the booking type, for example Cancel court booking, Cancel public match or Cancel bespoke booking.
For each player, choose Full refund, Partial refund (enter the amount) or No refund.
Check every player's choice.
Click the Cancel … button in the dialog to confirm. Click Close to go back without cancelling.
What players get back
Full refund goes back to the original payment method. If the payment was only held and not yet charged, the hold is released and nothing is charged.
Partial refund can be up to the amount still refundable. If the payment was only held, the part you keep is charged.
Refund remaining appears instead of Full refund if the payment was already partly refunded.
If your club has Refund to Club Wallet switched on, the options read "(Club wallet)": the card is charged and the refund is given as club wallet credit.
Unpaid payments are cancelled automatically.
Marked as paid and Free of charge payments show "No refund available for this payment".
The Nettla booking fee isn't refunded once a payment has been charged.
Your cancellation rules don't apply
When you cancel, the refund percentages on Settings → Rules & Limits → Cancellations aren't used. You decide each player's refund.
Special cases
Recurring bookings: you can only give club wallet credit or no refund. See "How do I cancel a recurring booking or refund cancelled sessions?"
Linked activity sessions (courses): later sessions show Cancel single session, with only No refund or Refund to wallet. Cancelling the first session of a linked series cancels the whole series.
Unavailable blocks: Cancel unavailable deletes the block.
Good to know
You can't refund a player without cancelling the booking or removing them. To refund one player, remove them instead: see "How do I add or remove a player on a booking?"
All cancelled bookings are listed under Calendar → Cancellations.
