moving house

I moved house with you. My moving out day is 22/12/2018 and moving in to a new place on 23/12/2018. Bulb let me know you will start supplying me on 5/1/2019. What about days between?
thank you for your answer
kind regards

As I understand it when you move the old supplier continues to supply until the switch date in your case this would be Bulb and then Bulb.

@bostjan, you will need to pay the current supplier of the house for those 5 days.

You’ll need to take readings when you move in to send to the old supplier, and readings 5 days later to send to Bulb as your switch date readings.

The old supplier will then bill you for the difference.
