New bike fettling. What needs tightening etc?

markt.safc

Getting my first ever brand new bike tomorrow after only ever making do with 2nd hand and I was wondering if i need to check bolts etc after a ride or two. And if so, what needs checking?
Incidentally i will be putting my juicy's on (front and rear), my bars and stem and my seatpost and saddle.
I'm getting the bike online from a shop in London. I'm in the NE hence the question. Otherwise, the shop would have been doing it.

Check everything before you ride it the first , then just do a regular once over. I give it a visual check each ride, other things when I clean it (from every ride to once or twice a month depending on the weather).
Generally very little loosens by accident.
