How does EV Optimise billing work?

Two smartphone screens showing EV Optimise charging history and cost savings. The left screen lists charging sessions from April and March 2024 with dates, times, and costs. The right screen displays a session summary with energy delivered, session duration, total cost of £3.72, and a message stating £5.55 was saved through smart charging.

You will be charged at your normal electricity unit rate for charging your EV. The difference between your normal tariff rate and the smart charge rate of 9p per kWh will be credited back to your account. This credit will be shown as a separate line item on your bill, making it easy to see your total savings for each billing period.

The credits for your previous month smart charging sessions are applied by our billing team on the first week of every month. These credits will appear on your next generated bill.

You can get a detailed breakdown of your smart charging cost and savings anytime via the EV Optimise dashboard on the ScottishPower app:

Tap ‘Session Overview’ for cost and savings after each charge.
Tap ‘View all history’ for a monthly breakdown of your last 20 sessions.

The smart charging credit you receive from EV Optimise won’t affect your Direct Debit amount. The EV Optimise credits will accumulate in your online account balance. You may choose to change your Direct Debit amount or request a refund in your online account.

Frequently asked questions

Check when credits are applied: Smart charging credits for the previous month are applied by our billing team during the first week of each month. They will appear on your next bill after that.
Make sure you’ve been smart charging: Open the ScottishPower app and go to the EV Optimise dashboard. Check the “Charging history” section to confirm you have completed smart charging sessions during your last billing cycle. If you can’t see the “Charging history” section at all, you most likely have not been smart charging and are not eligible for smart charging credit. Please see our smart charging support article for help getting started.
If you have smart charging sessions but still no credit: If your charging history shows one or more smart charging sessions during your previous billing cycle and you still don’t see any credit on your bill, please contact our Support team for assistance.

There may be differences between the charging cost information you see in the ScottishPower App and your car or charger manufacturer apps. This can be due to assumptions made by third parties about your tariff, energy losses, and other factors. ScottishPower is not responsible for the accuracy of data supplied by other parties. Any discrepancies should be addressed with them.

Your smart charging savings are shown in the EV Optimise dashboard and match the credit applied to your bill. These savings are not currently reflected in the Energy Usage or Energy Insights graphs.

If you believe your credit is incorrect, please contact our Support team for assistance.
