650 PAYMENT

Hi my sister and I live together and each receive IR esa and Pip individually.
.The gas/electricity bill is in her name and I wondered if this means she and she alone will recive the 650 and not myself-i.e.is it one payment per household bill rather than a payment each?
Ditto with the 150 payment-does that just go to the bill holder?
Sorry if Ive posted this twice and Im asking the obvious,
Many Thanks.
