Can I manually add a top-up?
What happens if payment for my top-up fails?
If a top-up is required for your plan, we'll automatically attempt to charge the payment method linked to your account. If payment fails, the top up will not be added and we'll notify you with instructions on how to correct the payment, so you can avoid being charged the higher off-plan rate.
If a top-up is not successfully added before your next renewal date, any usage accrued from the time you exceeded your kWh allowance will be charged on the off-plan rate.
