Switching to Bulb

I just switched to bulb today. Was surprised they didn’t ask for my current supplier details and account info. How do they know who to contact?

I assume you mean you joined Bulb today, the switch from your old supplier to Bulb takes place 21 days after joining Bulb (assuming no problems).

There is a national database of meters and Bulb hence can find out your current supplier from your home address.
