How long do front door panels take to arrive?

On saturday I got locked out and smashed a front door window panel in the process of trying to get in. A window man came today to reglaze the window, but told me it wasn't possible, and I have to get a new front door panel, (not a whole front door, and not the frame, it's a UPVC door). Does anyone know how long that part takes to arrive once ordered?How long do front door panels take to arrive?That would probably be a good question to ask the person you order it from.....
