Moving In

I have just signed up to bulb with the address I will be moving to in 2 week (currently exchanged contracts in a house and waiting for completion). How will the first bill work - am i going to be charged for energy bills from now until the 2 weeks? Switch is due on 16th and so is the first bill?

Please see here

@Tortor12 Your first payment will come out on the 16th (we take payments in advance) and the first bill will be produced on the 16th of sepetmber, after we have been supplying the property for a month. For the next 2 weeks, all energy used at the property is liable to be paid to the old supplier
