There weren't live launch shows until the house moved to Elstree.

For series one the housemates had been living in the house for several days prior to the first episode airing.

That is fairly typical for the North American versions. They typically get a weeks worth of footage before the launch shows and the feeds turn on the evening of the launch. Bad side is sometime things happen the week of the move-in that we dont see.
I'm here to give you something to talk about!
