Use the same method you used to initiate the session, so either tap your contactless or RFID car or re-open your WebPay or App charging session.
If you're struggling to end your session, call our 24/7 helpdesk, who will be able to give you instructions over the phone.
Please don't worry...even if you're still plugged in, you'll only get charged for the amount of electricity you've actually used. Once your battery is fully charged, it can't take on any more power, and you won't have to pay any extra.
If you need to get in touch, you can find our contact details here. We're available to help 24/7.
