Previous supplier

How do you know who my previous supplier is? There hasn’t been a question pertaining to it and the help centre just says you’ll handle the switch, but how do you know who it is?

Thanks

Kim

Hi @kim413 - you don’t need to worry about that. All suppliers pull information from two national databases - one for electricity and one for gas.

Your property is listed on those databases with your two meter supply numbers - an MPAN for electricity and an MPRN for gas.

Those numbers allow any supplier to see who currently supplies you.

Suppliers communicate to each other via third parties called data collectors using communications called dataflows. When you sign up to Bulb, we get your MPAN and MPRN numbers and automatically send a dataflow off to the supplier associated with it.

Hope that clears things up :slight_smile:
