Do you get the ceremony time when you "give notice"?

Sorry, no idea about any of this. We've found a venue we like and they said they can't raise the invoice until the ceremony time has been booked with the local council. Does that happen when we give notice?

Separately, is there a step-by-step guide on the bare bones of a wedding anywhere? We have found a lovely venue, will have about 60 people, and our friends will play instruments. Apart from that, we just need to know the minutiae of how to actually get the deed done. I have checked gov.uk but it only goes as far as 'giving notice'.
