When you use Apple or Google Pay we reserve £40 from your bank card as a holding fee. 

When you've finished charging we calculate the cost of the electricity you've used and then refund you the difference (so you only pay for what you've used). This normally shows up in your account the same day, but it can take up to 5-10 days. If the partial refund is not cleared within 10 days, please contact your bank directly.

If you still have any questions regarding billing then you can call us on 0800 086 9606 (Option 2).
