Welcome to the forum,
If you're on a fixed rate tariff, you'll pay a month in advance for your energy. If you're on our Simpler variable rate tariff, you can choose to pay on receipt of bill. You can edit the date and amount of this payment via your online account - more info in our guide here.
It sounds like there's been a Direct Debit check in on your account. If you can't afford the increase, we can try a lower amount - if you've got a debit balance the recommended amount will clear the debit balance in 3 months and leave you with a £0 balance at the end of your contract.
Don't forget you can make one off payments on your online account if you've got a debit balance!
