Two houses sign up

Hi there.
I’ve recently switched to bulb for my home but I want to also switch another house that I pay gas/elec for to bulb. Do I need to sign up again as another user or is there a way I can add another house to my account?
Also, are there any benefits or discounts that come with this?
Does the ‘refer a friend’ benefit apply if I open a seperate account for the other property?

Thanks for your help.

Hi Amy, sure, you can sign your other property up using

At the end of the ‘join journey’ the website will then note ‘It looks like you’ve tried to sign up already. Please login with the username and password you used last time.’

All you have to do is put in your usual password. That will be enough for it to know that it’s the same person (you) for each property.
