They are similar (as there are certain things you have to say legally - but that tends to be the stuff they ask/prompt you) but with no mention of god. We were allowed to choose from several or write our own. They sent us a pack when we booked it with everything in.
Yes they did give us a 'kissing moment' but don't know if that's down to the superintendant registrar. They also read a fucking awful poem (at least it made me laugh) that we hadn't requested (we didn't want any readings).
The ceremony was extremely short - 15 mins max. But we'd gone for the shortest version of everything and no readings, no big bride's entrance etc.
