Paying your final bill
Once the switch is underway, your supplier will ask for meter readings, so they can have a starting point for your supply — if you've been switched to a new supplier, these readings are also sent to your original supplier to calculate the final bill so you won't be paying two companies for the same energy.
When your switch is complete, your former supplier will generate a final bill for you based on your current meter readings (your new supplier will send these to your original supplier as part of the switch process).
Claiming money you're owed
If your account is in credit when the final payment is taken, your former supplier will refund the money straight to your bank account.
Sometimes suppliers can be a little slow in processing refunds, so if you're ever worried about the state of play, it's worth getting in touch with them to chase things up — we can't usually do this unless we have named authority on your account.
Cancelling your direct debit
As the switch process can take up to 5 weeks, and can be stopped or reversed, your original supplier will bill you as normal during the switch period and then refund any credit balance remaining after they generate your final bill.
Sometimes, a former supplier will continue taking direct debit payments to clear a debit balance that remains on a closed account.
Once the switch process is underway, if you'd prefer, you can cancel your direct debit facility for your former supplier with your bank, and the company will send you a final bill to pay as a lump sum.
