Do You Charge More for Going on Location?

Most of the time i go on location, it's within central london. Most of my stuff is ready to go in the studio all times. I've got t pack everything down, put it into cases, then when i get there, set it up and then do the whole thing in reverse at the end of the day. And so this extra time and effort involved from a practical point of view. Ad that you wouldn't have to do if you were in your studio where you know where everything is,. It brings me back to the days when i would shoot weddings.
