Getting your banns read

I don't think it matters, as long as you check your post there (as they will probably send you stuff), it shouldn't be a problem.

If you don't officially live with your partner then yes you have done the right thing.

I assume your post etc goes to your parents? And that that's where you're on the electoral role? Then yep, you've said the right address.

Yes all my post goes to my parents and im registered on the electoral role there.

Glad ive done the right thing :-)
