Buying broadband for new house?

[Luke]

Considering the fact the Internet service providers take around 10 days to get a working broadband connection to your house, could I pay for a plan in advanced for the home I am moving into so it will be ready for when I officially move in. Bare in mind that this house is empty and has no electric going to it. It already has a phone line socket so I could simply purchase a plan for that address.

Please let me know if I'm forgetting anything that wouldn't allow me to do this. Thank you for your comments.
Just a side note, I am a first time buyer so there is no existing broadband plan in my name so whatever plan I choose with be brand new and I don't have to switch from my previous home.
