A pre-authorisation is a temporary hold placed on your credit or debit card to confirm it’s valid and has enough funds to start your EV charging session. If you have mobile banking, you may see this amount pop up. When you finish charging, we tell your bank the real amount you spent, they deduct it, and arrange to unreserve the pre-authorised amount. This process can take a few minutes to a few days depending on who you bank with.
Note: For EV charging via the Shell App, the pre-authorisation amount is £55.
