Switch Over

Hi Bulb
It’s been 10m since I switched so can’t remember this detail…
My friend has just signed up with my link and email come to say will switch 18th Sept
She says the form did not ask for her current supplier name. How does she provide this or is there a central register for you to find out yourself?
What happens next

I cant remember if I was asked for previous supplier, however there is a national register as all readings have to be verified for both companies before the readings are used.
If Bulb have accepted the switch then you should not have to do anything else.

@LisaD as @scudo says you don’t need to do anything else, we can find out your previous supplier from your address.
