Yesterday I had my first Bulb payment taken by direct debit, my old supplier also took their monthly payment when I was told my final bill would be calculated in 6 weeks…is this correct?

Hi @Foxy sometimes a previous supplier may take their direct debit on the normal day of the month. Once the final bill is issued, which will be a maximum of 6 weeks from the switch, they’ll total up your consumption and your payments and settle any refund / final payment.
